Good day. I am implementing a CRM for fleet management on NestJS with access rights management, accounting for vehicles, drivers, rentals, payments, finances, and a complete history of changes. I will separately implement a Telegram AI Assistant through OpenAI Function Calling, so that text commands are automatically converted into API calls without using regular expressions. I am ready to start immediately. I would appreciate the opportunity to collaborate.
Budget: 27000 UAH Deadline: 90 days
Alexandre, you have a complex but very interesting CRM project: fleet management, finance, roles, change history, and most importantly — a Telegram AI assistant. I have 6+ years in PHP/Laravel and CRM development, so I can immediately design a reliable architecture, access rights, modules for vehicles/drivers/rentals/payments, and change auditing. For the AI assistant, I will implement structured outputs and function calling without regex, with clarifications and calling the necessary actions. I am ready to discuss the stages and priorities.
Budget: 25000 UAH Deadline: 8 days
Good day. I can build the system step by step: authorization and roles, dashboard, modules for cars/drivers/rentals/payments/repairs, change history, and notification architecture. I am also separately considering a Telegram AI Assistant with Function Calling and structured responses. I have 8 years of experience in web development and implementing complex turnkey systems — I can discuss the first stage.
Budget: 27000 UAH Deadline: 21 days
Alexander, I see here not just a CRM, but a complex system with roles, finances, change history, and an AI assistant. I can design the architecture so that the modules for cars, drivers, rentals, payments, and repairs work together seamlessly, while Telegram/built-in AI correctly processes requests and clarifications through function calling. I work with PHP, MySQL, JavaScript, and Telegram bots, so I can assemble this step by step and without chaos. Shall we discuss the start?
Budget: 23750 UAH Deadline: 14 days
Good day, I have over 5 years of experience in development, having worked extensively with SaaS platforms, AI integrations, and complex admin panels.
My own product Throngwatch: SaaS analytics for Discord communities, created by myself. I have attached an example, please take a look.
I will deliver a turnkey solution: authorization with roles, a functional dashboard, cards for cars and drivers, accounting, change history, integration of a Telegram bot with an AI assistant, and Function Calling via OpenAI. For the first stage (core system and basic bot integration), I estimate 2-3 weeks; I will provide the exact cost after a few clarifications.
What features of the Telegram bot are critical at the start (booking or analytics)? Is it necessary to support multilingualism for different roles?
I look forward to your message in private!
Budget: 27000 UAH Deadline: 12 days
Good day! The project has a well-thought-out structure, and we are ready to implement such a platform "turnkey."
Our team has deep expertise in developing complex web systems with multi-level roles and access rights. We also regularly integrate AI assistants of any complexity - in particular, based on OpenAI for both Telegram and AI assistants.
For such large-scale projects, we recommend starting with the Discovery Phase. Within this phase, we will:
1. Prepare a detailed technical specification (TS).
2. Create an interactive clickable prototype of the interface logic and AI interaction.
3. Select the optimal technology stack for your loads.
4. Provide the most accurate and adequate estimate of costs and development timelines.
To better understand the context and scope of the project, please let us know:
Preferred stack: Do you have a dedicated preference for technologies (e.g., React/Next.js, Node.js, Python/Django), or can we propose our stack for your tasks?
Budget: What is the approximate budget you are aiming for to implement the entire system (or MVP)? This will help us select the right scope of solutions within your resources.
We are ready to discuss the details and answer all questions. We look forward to collaborating!

Hello Alexander!
I have reviewed the project description. The task is interesting, and in my opinion, this is not just about a CRM, but a full-fledged fleet management and rental system with financial accounting, change history, and an AI interface.
I can implement the project using Laravel + Vue 3/Inertia.js with PostgreSQL. I suggest building the system modularly, so that in the future we can easily add GPS, push notifications, a mobile application, and other integrations.
I would like to pay special attention to the AI Assistant. I would implement it through OpenAI Function Calling / Structured Outputs with a separate API layer: the assistant determines intent and entities, requests clarification if necessary, and then calls strictly defined backend functions of the CRM. This will allow safe operations with rentals, payments, cars, and repairs, rather than just interpreting text.
I would also provide a complete system of roles and permissions, financial accounting for each vehicle, an audit log of all changes, and a unified API for further integration with Telegram, notifications, and other channels.
I am ready to propose a phased development, starting with the MVP of the main modules, after which we can gradually add the AI Assistant and additional features.
Based on preliminary estimates, the full implementation of the described functionality significantly exceeds the budget of a standard CRM and requires phased development. I am ready to review your complete technical specifications and propose an optimal architecture, timeline, and budget.
Budget: 27000 UAH Deadline: 20 days
Good day! The task is clear — a unified system for a fleet: rentals, payments, debt accounting, repairs, maintenance, with built-in accounting and a Telegram AI assistant. The project is right in my zone.
Why close: I develop and manage a commercial SaaS with multi-role functionality, rights segregation, and financial accounting — the core of such systems (roles, backend rights, logging, money) is daily practice for me.
Stack: Next.js (React) + TypeScript, backend NestJS + PostgreSQL — structured code for long-term development, rights segregation (Owner / admin / manager / driver / accountant) at the server level and scalability without rework.
What I lay down from day one:
Change history — architecturally, not "feature at the end": who, when, what changed, old → new, across all entities.
Finance and cash — accounting of money on the server with logging, amounts in Decimal (not float), profit for each vehicle.
Statuses and connections — creating a rental changes the vehicle's status, creates a debt, writes to history; closing a repair updates expenses. A single model of transitions, not disparate actions.
GPS and notifications — I will prepare the architecture for connections (push / Telegram / Email), without implementation in the MVP.
Telegram AI assistant — what I am actively working on. I will implement it correctly: messages → OpenAI with Function Calling / Structured Outputs → intent and entity recognition (vehicle, driver, amounts, dates) → if necessary, a clarifying question → API method call → result. No regex parsing — only structured calls, so the assistant executes commands ("book Aveo 3661 for Sergey from Monday") and provides analytics ("which car is the most profitable"). It can also be embedded in the CRM as an operator assistant.
The project is phased — I suggest breaking it down into logical stages (core+roles → vehicles+drivers → rentals+payments → repairs+finances → history → AI assistant) with separate evaluation and acceptance of each.
Clarification before evaluation: is full-fledged accounting needed (transactions, reporting) or just accounting of income/expenses/debts by vehicle and cash? This greatly affects the scope.
Examples of work: https://hashtech.dev/, https://services-helper.com/ru, https://zapys24.com/, https://dev-market.enez.com.ua/, https://www.vbk-partner.com/
I will show my own SaaS with an admin panel and roles in the dialogue. I can start after agreement.

Hello
Currently, there is a CRM/ERP system for driving schools (it can possibly be adjusted for your car rental business), as the accounting system is already in place, just needs some adjustments. We are also integrating AI.
So we might be able to reduce the project's cost and shorten the implementation timeline.
In your description, the text is slightly off.
Budget: 27000 UAH Deadline: 30 days
Hello!
I can take on the development of such a web platform in stages because what is needed here is not just an accounting cabinet, but a full-fledged CRM system for a fleet with roles, rentals, payments, repairs, finances, change history, and a solid foundation for scaling. In such projects, it is especially important to properly think through the architecture, access rights, relationships between modules, and status logic from the start, so that the system does not fall apart after the first real processes are launched.
I have experience in developing complex web systems on Laravel with authorization, user roles, CRM logic, change auditing, API integrations, and financial modules. I am particularly interested in the block with the Telegram AI Assistant because it can be made truly functional through Function Calling, with intent recognition, entities, clarifications, and triggering the necessary actions in the system, rather than through fragile text parsing.
I can help break the project down into manageable stages, so that we can first build a reliable core of the system and then calmly develop AI, notifications, GPS, and other modules without chaos in the logic.
Please write in private messages, and we will discuss the details, timelines, costs, and the phased start format.
Budget: 27000 UAH Deadline: 19 days
If scalability is built in from the very beginning, it will be possible to integrate GPS, a mobile application, new payment services, analytics, or additional AI features in the future without costly rework.
We are particularly interested in the block with the Telegram AI Assistant. Recently, we developed an AI assistant for one of the largest private clinics in Dnipro, where it automates user interactions and business processes. Therefore, we understand well how to build similar solutions through OpenAI Function Calling / Structured Outputs, so that the AI not only responds to messages but operates as a full-fledged operator: analyzing requests, asking clarifying questions, and performing actions via API.
We recommend starting with a technical audit and designing the architecture, after which the system can be implemented in stages. This will help avoid unnecessary costs and make the platform ready for scaling.
Our portfolio: https://winbixai.com/uk. The website does not showcase all implemented projects, as some of them are under NDA. If interested, we would be happy to send additional CRM, AI solution, and business automation system cases in private messages and provide more details about the implemented AI assistant.
Budget: 23500 UAH Deadline: 15 days
Alexandre, the critical moment here is not the number of modules, but that the chat assistant creates rentals and moves money. If OpenAI confuses "Sergiy" with "Sergiyko" or inserts the wrong amount into the driver's debt, the system will not pay for this mistake. Therefore, I must structure the output of Function Calling before calling the API: the model returns parsed fields, the bot searches for a real driver and car in the Postgres database, shows the operation card, and waits for confirmation. Without this step, there will be no record in finances.
I write the change log at the service layer level of Laravel, so the assistant's actions are automatically logged with a source tag. I will gather the dashboard, repairs, and complete accounting according to your list after the end-to-end "rental-debt-payment" process works with real data.
How many cars are in the fleet now?
Budget: 999 UAH Deadline: 1 day
Good day, Oleksandr.
Your fleet is currently scattered between OLX, paper contracts, and spreadsheets — and the Telegram assistant should become the single interface through which the manager says "book the Aveo for Serhiy from Monday" and the system automatically creates the rental, calculates the debt, and changes the car's status. For this to work safely, Function Calling must rely on a reliable API with validation for each action — otherwise, a model error in amounts or car numbers will turn into real financial losses. That is why the core CRM with roles, finances, and audit changes is being built first, while the AI layer is applied over the ready, verified endpoints.

Budget: 27000 UAH Deadline: 30 days
Good day.
The project as a whole spans more than one month, so it needs to be divided into stages:
1. Database schema, authorization, roles and access rights, change history mechanism, vehicle module.
2. Drivers, rentals with statuses and debt accumulation, payments and cash register.
3. Repairs, expenses, finances for each vehicle, reports.
4. Dashboard, calendar, notifications (push, Telegram, Email).
5. AI assistant in Telegram and within the CRM.
$27,000 and 30 days in the rate is for the first stage.
The order is not random. The dashboard is not first: it is a showcase over data that does not yet exist. The assistant is last for the same reason - it calls functions of your API, and as long as the functions "create rental" and "accept payment" do not exist, there is nothing to call. Change history, on the contrary, is in the first stage: it does not appear retroactively, it has to be rewritten along with half of the code.
Regarding the assistant: Function Calling and Structured Outputs, entity search with clarifying questions in case of ambiguity, mandatory confirmation for everything that moves money and statuses. "Sergey paid 4500" should not silently deduct debt from the wrong Sergey.
Stack: NestJS/TypeScript, PostgreSQL, Redis, Angular + PrimeNG, S3-compatible storage for documents and photos, a separate service for the Telegram bot.
I have worked with the OpenAI API: text parsing and extraction of structured data about orders. The domain is close; I developed a system for freight transportation, where there are the same statuses for equipment, debts, and calculations for each vehicle.
The rate is $15/hour, and I will evaluate further stages in the same way by hours.
Before starting, we need to discuss business rules: how debt is calculated during extensions, how a deposit differs from a pledge, what happens to the debt in case of an accident.
I can start with the database schema and decomposition of the first stage into tasks.
Budget: 20000 UAH Deadline: 20 days
Hello!
Regarding the assistant and accounting, there are four things that will define the architecture.
Assistant: the model only provides a structured function call, while "Aveo 3661" and "Sergey" are resolved by searching the database, because guessing the model ID is not allowed. If there are two matches for "Sergey," the assistant asks a clarifying question instead of making a random choice.
Second, and this is more important: the assistant handles money and debts. Therefore, before executing, it shows the operation card ("Extend the rental of Aveo 3661 to Sergey, 4500 UAH, for a week") and waits for confirmation. One misunderstood phrase can quietly disrupt the driver's balance, and correcting it later is more expensive than confirming with one tap.
The history of changes is recorded at the service layer level, not in each handler. This way, the assistant's actions are logged automatically, marked as having gone through it. Otherwise, the AI will be outside of the audit, which is precisely where transparency is needed.
I account for events (rental, payment, repair) rather than storing separate editable numbers. Profit for each vehicle is calculated, so the figures on the dashboard and in the vehicle card do not diverge.
I will implement the other modules on your list as described, and I will architecturally include GPS and notifications without implementation in the first stage.
I propose a phased approach: the core accounting (authorization with roles, vehicles, drivers, rentals, payments) in 3 weeks, then finances, repairs, history, and dashboard, followed by the Telegram assistant.
I am ready to start. I look forward to collaborating.
Budget: 18000 UAH Deadline: 14 days
Good day. It is critical to first build the core CRM and API, and only then connect the AI assistant on top of it. Function Calling makes no sense if there are no reliable functions for creating rentals, accepting payments, extending contracts, and changing vehicle status.
I would start with the first end-to-end flow: roles - vehicle - driver - rental - debt - payment - change log. For financial and critical actions, the assistant will first display the recognized data and wait for confirmation, so that one erroneous amount or vehicle number does not alter someone else's record.
In the first stage, I will prepare the architecture, database, API, main modules, and a working proof of Telegram commands through Structured Outputs and Function Calling. After that, we can separately assess repairs, full accounting, notifications, GPS, and the analytical assistant.
Budget: 27000 UAH Deadline: 15 days
The key here is not the CRM, but that the assistant writes in the database from the chat: "Book Aveo 3661 for Serhiy" must fall into the same rental table as the form. Therefore, before recording, the bot shows a breakdown — car, driver, dates, amount — and waits for "yes," otherwise one misunderstood number will be assigned to someone else's car.
I take Python and Postgres: authorization with roles from owner to accountant, car cards with VIN, maintenance, and insurance, driver cards with debt and deposit, rentals, payments, repairs, finances for each car. Every change is logged with the old and new values. The assistant operates on Function Calling: intent and entities come with ready fields, a separate API function for each action, so the question "who pays today" reads from the same database. The working outline of car-driver-rental-payment with your data will be opened on the 10th day.
I redesigned the AI assistant for the CHARACTER fleet after the unsuccessful bot of previous performers, while the change accounting bot for Profline Group manages roles and operation logs. There are currently zero reviews in the profile — this is visible next to the rate, so we work with a Safe: funds remain frozen until you accept the stage. I am laying GPS and notifications as connection points, without tying to a specific tracker.
27,000 UAH, working version in 10 days, stabilization up to 15. Just tell me one thing: how many cars are in the fleet now — up to 20 or more than a hundred. I will see the answer — I will return the breakdown of stages with what is included in the first launch.
Budget: 27000 UAH Deadline: 45 days
Hello, Alexander!
The technical specification is written by the person who runs this business — it's evident from the fact that it includes driver debts and overdue payments, not just a pretty dashboard. So let's get straight to the point.
The main factor that determines the fate of such systems is not the functions, but whether the manager will use them instead of the usual notebook or spreadsheet. If issuing a car takes longer than writing it down on paper, the system will quietly die within a month. Therefore, frequent actions — issuing, returning, accepting payments — should be done in two to three clicks from a phone, not through a form with twenty fields.
Second — money. Accounting for debts and bookkeeping is not "just another module," but the most risky part. If a payment is recorded twice or lost, you will hear about it from the driver, not from the report. I include a history of changes for each operation: it shows who, when, and what was changed, and any figure can be traced back to the original entry.
Regarding the AI assistant, I will be honest: it only makes sense after the data has already accumulated in the system. On an empty database, it will produce vague phrases instead of being useful. Therefore, in the first stage, I will incorporate it into the architecture but connect it later — this way, you won't pay for a function that currently has nothing to work with.
I propose the following order of work:
1. Authorization, roles and permissions, "Cars" module, issuing and returning, basic dashboard.
2. Payments, debts, contracts, maintenance, and insurance.
3. Accounting, reports, AI assistant.
After the first stage, you will already have a working system into which you can enter cars and issuances, rather than half of everything at once. And you will see my work before you invest in the full scope.
Stack: Python (FastAPI) on the backend, React and TypeScript on the frontend.
Two questions to avoid guessing. How many cars are currently in the fleet and how many people will be working in the system simultaneously? And is contract signing the generation of a document for signature on-site or a full-fledged electronic signature (Diia, KEP)? This significantly affects the scope of the second stage.
Budget: 27000 UAH Deadline: 20 days
Hello.
The project is interesting, especially the fact that you are immediately laying the architecture for scalability, rather than just a CRM.
I have experience in developing complex web systems with user roles, analytics, REST/API, integrations, and AI. I understand that it is important here not only to implement functionality but also to build the architecture correctly so that new modules can be added without problems in the future.
I would suggest breaking the project into stages:
designing the architecture and database;
developing the main CRM modules (authorization, vehicles, drivers, rentals, payments, repairs, finances);
a change history and notification system;
integration of Telegram AI Assistant;
testing and preparation for further scaling.
I fully support your approach to AI. I would use Function Calling / Structured Outputs instead of text parsing so that the assistant can correctly understand requests, ask clarifying questions when necessary, and call the required API methods.
I would also immediately lay the architecture for:
Telegram, Email, and Push notifications;
GPS integration;
electronic signing of contracts;
accounting and reports;
further expansion of functionality.
For such a project, I would use the stack:
Frontend: React / Next.js
Backend: Node.js (NestJS) or FastAPI
PostgreSQL
Redis
Docker
OpenAI API
WebSocket for real-time updates.
This is not a project that should be done "head-on." First, the system needs to be designed correctly, and this will save a lot of time and resources in the future.
Budget: 27000 UAH Deadline: 30 days
Good day!
Your project looks interesting, especially considering the future scaling and integration of an AI assistant.
I have experience in developing CRM systems and mobile applications, so I understand well how to build such solutions with future development in mind.
In private messages, I can show you the CRM system for managing parking that I have already implemented. My profile also has a portfolio with other projects.
It would be good to discuss a few details: is there already a ready design (Figma), technical specifications, and API, or will all of this also need to be designed?
If everything is satisfactory, I would be happy to discuss the project in more detail and propose an optimal implementation plan.
Budget: 27000 UAH Deadline: 25 days
Hello! The project is described very clearly. I have extensive experience in developing complex CRM systems with financial accounting, access roles, audit logs, and artificial intelligence integration.
Recommended technology stack:
- Language and environment: PHP 8.2 - 8.4
- Framework (of choice): Laravel (versions 10.x - 13.x) or Symfony (versions 6.4 LTS - 7.x)
- Database: PostgreSQL / MySQL
- AI Integration: OpenAI API (GPT-4o / GPT-4o-mini) via Structured Outputs and Function Calling
- Frontend: Blade/Twig + Tailwind CSS + Alpine.js (fast, lightweight server-side UI)
How I propose to implement the architecture:
1. CRM and backend:
- Flexible role and permission system (RBAC).
- Financial module: cash register, debts, profitability calculation for each vehicle.
- Auditing module: automatic recording of old and new values for any changes in the system (Audit Trail).
- REST API for communication with the Telegram bot and services.
2. AI Assistant (OpenAI Function Calling):
- Using OpenAI API with strict schema validation via Structured Outputs (JSON Schema).
- The bot converts user language into DTO and calls CRM API methods (creating bookings, changing status, analytics requests).
- Bidirectional communication: the bot can clarify details if mandatory parameters are missing in the message.
Implementation stages:
Stage 1: Database architecture, authorization, basic modules (Vehicles, Drivers, Rentals, Finance).
Stage 2: Dashboard, audit log, notifications.
Stage 3: Integration of Telegram AI Assistant with Function Calling.
Cost and timelines:
- Budget for the first stage (basic backend + CRM): 65,000 UAH.
- Total budget for the complete package: 130,000 - 150,000 UAH.
- Deadline for the first phase: 20-25 days.
I am ready to discuss the details of the first stage and agree on the final estimate!
Budget: 18000 UAH Deadline: 7 days
Alexandre, this is not just one CRM screen, but a system with a financial contour, change auditing, and an operator that must securely execute commands via API. I propose a paid first stage: within 7 days, I will design roles/permissions and a data model, describe the API for cars, drivers, rentals, payments, and repairs, prepare a prototype of key screens, and a working proof of the Telegram bot through Structured Outputs/Function Calling with confirmation of dangerous actions. The result will be a database schema, OpenAPI, prototype, test scenario, and an assessment of the next milestones. The cost is 18,000 UAH through Safe; full implementation is priced separately. Are you ready to start with one end-to-end scenario "booking → debt → payment"?
Budget: 20000 UAH Deadline: 90 days
I already have a practically ready similar solution - it can be quickly adapted and launched.
I suggest discussing the details now here on the marketplace, I am available (:
At the start, do you need a full accounting system with entries and regulated reporting, or management accounting for cash, debts, income, and expenses?
Should the actions of the AI assistant be performed after user confirmation, or can safe operations be conducted automatically?

Hello!
The key task here is not just to create a CRM for a fleet, but to integrate rentals, vehicles, drivers, payments, repairs, and finances into one system with clear business logic and the possibility of further scaling. I would build the platform modularly so that each stage can be launched and tested separately without having to redo the architecture later.
I have relevant Full Stack development experience:
* React / Next.js + Node.js / Express
* PostgreSQL, MongoDB, Supabase, Prisma
* booking and order management systems
* business dashboards, roles, and access control
* payment and financial logic
* integrations with OpenAI API and Function Calling
In particular, I developed a yacht charter booking platform with booking management and business logic, as well as business dashboards and SaaS services.
The Telegram AI Assistant can also be implemented correctly here through Structured Outputs / Function Calling: AI determines the user's intent and calls strictly defined backend functions, rather than directly modifying data.
I suggest first defining the MVP and breaking the development into stages: Core CRM → rentals/finances → analytics → AI Assistant.
I am ready to discuss the architecture and propose a specific implementation plan by modules.
Budget: 27000 UAH Deadline: 30 days
Good day.
I have done something similar for the US market (except without AI). I can do it on Laravel.
It looks like a long-term project; I estimate about 4 months or 250 hours (it’s unlikely to be faster, let’s be realistic).
Hourly rate is $10. It can be done in stages.
(The cost and timeline are indicated conditionally, as the system does not allow entering more than 27 thousand.)

Hello, I have reviewed the project and am ready to implement it. Please reach out so we can discuss all the details, choose the necessary technologies, and outline all the functionality!
Budget: 15000 UAH Deadline: 20 days
Hello, Oleksandr!
Here’s how I propose to implement your project (step by step):
Step 1: Database Architecture and MVP (Authorization + Cars + Drivers + Rentals). The secret to a reliable CRM for a fleet is the correct logic of relationships. We create a flexible database (PostgreSQL), where the status of the car (“Rented”, “Maintenance”, “Repair”) automatically changes depending on triggers. We implement a role model (owner, manager, accountant, etc.)
Step 2: Finance, Cash Register, and Change History. We integrate the logic for debt accrual, payment acceptance (cash/card), and automatic recalculation of net profit for each car considering repair costs. We set up logging (old/new value) so you can see every action of the managers.
Step 3: Telegram AI Assistant + CRM API. We develop an AI assistant. We write clear system prompts and function descriptions (tools) for OpenAI, so that the phrase “Sergiy paid and extended the rental for 4500 per week” instantly triggers the function extend_rental_and_pay(driver_id, amount, duration) in your CRM.
My tech stack for your task:
Backend: Python (FastAPI is perfect for AI integrations and high API speed).
Frontend: React.js / Next.js (fast, modern, and user-friendly interface for the admin panel).
Database & Cache: PostgreSQL + Redis (for queues and Telegram bot).
AI: OpenAI API (GPT-4o / GPT-4o-mini) + Native implementation of Structured Outputs.
Budget: 25000 UAH Deadline: 7 days
Good day.
My name is Denis, and I specialize in developing CRM systems on Laravel. I can offer a quality implementation of your web platform for fleet management.
I have extensive experience in developing similar accounting systems, role models, and finance. I have also worked closely with the OpenAI API (including Function Calling) and Telegram bots, so implementing a smart AI Assistant for managing rentals and repairs via text will be an interesting and quite feasible task.
Could you please let me know if you already have a ready design/mockups for the CRM, or can the interface be built on the basis of ready-made solutions (for example, Filament) to significantly speed up development?
Let's discuss the details, and I will be able to guide you on timelines and costs. Sounds good 🙂
Best regards, Denis

Good day.
I can implement this project comprehensively, starting with the design of the CRM architecture and ending with the implementation of the AI assistant and the launch of the system into operation.
I develop similar systems with a focus on scalability, security, and automation of business processes, so that in the future it will be easy to add new modules, integrations, and functionalities.
As part of the project, I can implement:
the design of the CRM architecture and database;
a system for authorization, user roles, and access rights management;
a Dashboard with key indicators for the fleet, finances, tasks, and statistics;
modules for vehicles, drivers, rentals, payments, repairs, and finances;
automatic accounting of income, expenses, profit, debts, and the history of each vehicle;
a log of all changes with user, time, and edits recorded;
preparation of architecture for Telegram, Email, and Push notifications;
integration of a Telegram AI assistant based on OpenAI using Function Calling / Structured Outputs without parsing with regular expressions;
the ability to work with AI not only through Telegram but also directly within the CRM as a personal assistant;
integration with other services via API and preparation of the system for further scaling.
The AI assistant will be able to create bookings, process rentals, extend contracts, accept payments, change vehicle statuses, answer analytical questions, find necessary data, and perform other actions in natural language without the need to manually work with the CRM.
Upon completion, you will receive a fully ready system with a clean architecture, all source codes, documentation, and the possibility of further development without being tied to a single contractor.
I would be happy to discuss the development stages in detail, propose an optimal technology stack, estimated timelines, and budget after reviewing all the project details.

Hello! I am ready to take on the development of the platform in stages — from architecture design and MVP to the financial block and AI assistant.
For implementation, I propose the stack Next.js + NestJS/Django, PostgreSQL, Redis, object document storage, and a separate API for the Telegram bot. I will immediately lay down roles and access rights, change logs, financial accounting for each vehicle, and the possibility of further integration of GPS, payments, and notifications.
The AI assistant will be implemented through OpenAI Function Calling and Structured Outputs: the system will recognize intent, find a vehicle or driver, request missing data, and perform actions only through secure API functions. For financial and critical operations, we will add mandatory user confirmation.
I suggest breaking the work into stages:
1. Authorization, roles, vehicles, drivers, and Dashboard.
2. Rentals, payments, debts, repairs, and documents.
3. Finances, reports, calendar, notifications, and action audit.
4. Telegram/CRM AI Assistant.
5. Testing, documentation, and deployment.
Approximately MVP — 2–3 months. Full first version — 4–6 months depending on the detail of accounting and integrations. Rate — $15/hour, I can prepare an exact estimate after discussing scenarios and priorities for the first stage.

You need a unified system instead of OLX, paper records, and scattered spreadsheets. Lead search, contracts, vehicle issuance, payments, and debt control should be in one place. I am ready to build a web platform with roles and permission segregation, with modules for vehicles, drivers, rentals, payments, repairs, and finance, plus a dashboard with vehicle statuses and charts. Separately, I will create a Telegram assistant: it understands text requests, determines intent and entities through Function Calling and Structured Outputs, clarifies details if necessary, and calls the required API functions instead of parsing text with regular expressions. I will lay the architecture for notifications, change history, and scalability. Let's discuss the stages and start developing the platform for your fleet.

Good day.
Regarding the AI assistant, the main point is that it cannot appear before the API that will be called. Function Calling is when the model triggers your functions. If the functions "create rental" and "accept payment" are not yet available, there’s nothing to trigger. Therefore, first the core with the API, then the assistant on top — otherwise, it will end up being the very parsing with regular expressions that you are refusing.
Stack: Django + DRF + PostgreSQL, Telegram on aiogram, front-end on React. Roles, permissions, and change history are established from day one — the audit log cannot be added later; it is rewritten.
Function Calling is not my focus. I wrote a desktop application where four families of LLM provider protocols are integrated under one interface, and a native tool-calling loop operates. Plus, bots on aiogram in production and payment tracking with charts on React/Recharts.
The project as a whole will take several months, and I won’t say otherwise. I suggest starting with the first phase: authorization and roles, cars, drivers, rentals, payments, change history. This is already enough to move away from paper and OLX. Next — finances, repairs, dashboard, notifications, and assistant.
I am ready to call and break down the phases by deadlines.

Good day!
I have reviewed the task. The project is extensive and essentially includes a CRM/ERP for a fleet, financial accounting, rentals, repairs, a change log, and an AI assistant. To avoid creating an unstable system, I suggest implementing it in phases.
In the first phase, we can launch an MVP: authorization and roles, vehicle and driver modules, rental creation, payment and debt management, repairs, a basic Dashboard, change history, and a Telegram AI assistant with Function Calling and Structured Outputs.
Estimated stack: FastAPI/Django, React or Next.js, PostgreSQL, Redis, Docker, Telegram Bot API, and OpenAI.
Before starting, I suggest separately agreeing on the business logic for debts, rental extensions, payments, and access rights, after which we can prepare the database structure, phases, and a precise estimate. I will be waiting for your response.

Alexander, I see before me the task of transitioning from disparate tools to a unified fleet management ecosystem that not only keeps records but also becomes the decision-making center for the business. I understand that the key challenge here is the logic of interaction between the modules of rental, service maintenance, and built-in accounting, in order to minimize errors in debt calculations.
I propose to start with designing the data architecture that will allow scaling the system from a few vehicles to a large fleet. After that, we will create a prototype with a functional dashboard that will display the status of vehicles and driver debts in real time, and we will implement an AI assistant for automating routine responses and reporting.
At what stage are the regulations for drivers and the financial documentation that you plan to automate first?

I propose to implement a CRM for a fleet with an AI assistant in Telegram. I have 5+ years of experience in Python, C#, REST API development, FastAPI, Django, Telegram bots, asynchronous systems, and AI integration. I understand your requirements: authorization modules, dashboard, cars, drivers, rentals, payments, repairs, finances, change history, notifications, and a key Telegram AI assistant with Function Calling. I suggest a phased development: first the core with authorization and basic modules, then finances and history, followed by the AI assistant. I will use FastAPI for the backend, React for the frontend, PostgreSQL for the database, and OpenAI with Function Calling for the assistant. I will ensure scalability and code cleanliness. The estimated price for the entire project is 3000 USD, with a timeline of 60 days. I am ready to start immediately and provide a detailed plan.
