Development of a web application for automating Viber dialogues with clients + SalesDrive + AI

Budget: 27000 UAH Deadline: 30 days

Greetings. The architecture of the task requires reliable processing of webhooks from TurboSMS, bidirectional synchronization with the SalesDrive API, and integration of LLM for strict RAG parsing of client text according to the article dictionary.

I will assemble an MVP web panel on React + Python (FastAPI) in 3-4 weeks (starting from $1200). I have experience with cascading integrations and state synchronization: I developed the backend for a trading MAM terminal with complex request management through the broker's API and a notification system. For AI text recognition, I will use the OpenAI API with output strictly limited to a structured JSON format, matching the request only with product IDs from the sent flyer. How is your product database for advertising flyers currently implemented in SalesDrive — is it a standard catalog with articles or dedicated custom entities?

Hello Valentina, I see here not just a chat-bot, but a complete chain: SalesDrive, Viber, webhook processing, and AI text recognition with error control. I have already integrated CRM/API, built PHP/Laravel modules, control panels, and dialogue state preservation scripts. For the MVP, the timeframe is 2–4 weeks; after reviewing the technical specifications, I will provide a more precise estimate. I also have experience with AI/LLM APIs. If you want, I can briefly describe the architecture and risks by stages.

Budget: 1000 UAH Deadline: 1 day

Valentina, I see here not just a Viber broadcast, but a complete scenario with SalesDrive, webhooks, dialogue states, and AI text recognition. I can design the MVP so that the manager handles orders, postcards, and scenarios, while the system automatically guides the client to confirmation and updates the CRM. I have experience with API/webhook integrations and AI/LLM for text processing. After the technical specifications, I will provide an accurate estimate of timelines and scope, as well as show relevant cases.

Budget: 10000 UAH Deadline: 14 days

Hello! I have done CRM integrations into messengers with transactional messages and response buttons. A practical question right away: Viber Business Messages only works through a connected business account with an API token — do you already have it set up, or is that also on me? This affects the start. I will create a web panel for the manager with order selection from SalesDrive and scenarios turnkey.

Budget: 14000 UAH Deadline: 10 days

Good day. Straight to the point of your list: the combination of SalesDrive + Viber dialogue + AI text recognition is exactly my area of expertise. I created a bot for an online store where customers write orders in free text, AI matches the items with the catalog and sends them via API — this aligns almost one-to-one with your steps 4–7. Plus, CRM with an admin panel and Telegram notification bots.
Three points regarding Viber through TurboSMS that determine the feasibility of the scenario — I’ll mention them right away to avoid surprises:

The Viber Business chat session lasts 24 hours from the first customer response (or up to 60 outgoing messages). Your scenario fits within this window, but if the customer is silent for a day — re-entry is only possible with a new transactional message. This is built into the logic.
For two-way chats with webhook, an active own Viber sender on TurboSMS is needed (a separate paid plan). Is it already connected and paid for? This affects whether we can test the incoming flow.
Buttons (“Yes, continue” etc.) — have you confirmed that clicks come back to the webhook as postback? Sometimes interactivity has to be built through a separate Viber bot — it’s solvable, but it affects the architecture.

How I propose to work (I don’t have reviews here yet, so — transparently and in stages): the first stage MVP — panel + orders from SalesDrive + one end-to-end Viber dialogue with AI recognition for one leaflet, working end-to-end. You confirm that the core works — we continue with the rest. I will specify exact timelines and costs after a detailed technical specification; for such a volume, a blind figure would be unfair. The core of the first stage can realistically be done in about 1–1.5 weeks.
Regarding your points: experience with CRM/API/webhook — yes; experience with LLM API for recognizing customer text — yes, this is my area of expertise; I will show similar projects in private messages.

Budget: 8000 UAH Deadline: 7 days

Good afternoon. I will implement integration with the SalesDrive API for retrieving and updating orders on Nest.js, and I will set up the processing of free text from the client through the OpenAI API for matching products with flyers. I suggest discussing the price and deadlines in private messages. I am ready to discuss the details and start working. I look forward to collaborating.

Budget: 10000 UAH Deadline: 12 days

Hello, Valentin! The scenario is clear, I see the key points as follows:
1. Dialogue as a finite state machine (FSM) — each order remembers its step, when passed to the manager, the scenario stops cleanly, without duplicates.
2. AI-matching without "inventing" products — only a structured list of IDs/articles from the selected flyers is passed to the prompt, the model works strictly as an entity parser (product + quantity), no more. This is a principle I have already used in similar AI sales agents (ShopAgent AI — Telegram/Instagram, catalog + strict retrieval).
3. A nuance with the Viber session through TurboSMS: steps 8-9-10 in the technical specification go automatically in sequence without buttons — if the session closes (message limit or 24 hours since the last client response), part of the tail may not reach. I will lay down the logic of combining/triggers based on client action, rather than blind batch sending.
Stack: FastAPI + PostgreSQL, webhooks SalesDrive/TurboSMS, LLM (Claude/OpenAI API) for matching, web panel for the manager (orders/scenarios/flyers/history/statistics).
Please clarify: is the Viber Business account in TurboSMS already verified, and is there access to the SalesDrive API for writing (updating amount/status)?

Budget: 15000 UAH Deadline: 18 days

I read the task completely. The scenario is clear: the manager selects an order(s) in SalesDrive → a confirmation of the order is sent to the client via Viber → upsell through advertising leaflets → AI recognizes the client's free text and matches it with the products in the leaflets → the upsell is added to the SalesDrive order → then status messages (timelines, inspection upon receipt, contacts).

Similar integrations have been done — examples: https://guardlabs.online/demo/crm-recruiting/ (form → Make → NetHunt CRM), https://guardlabs.online/demo/olx-monitor/ (automation on external API + notifications), https://guardlabs.online/demo/kava/ (bot with a dialog scenario).

Technical questions before starting:
1. Viber Business Messages — is the account already verified? Verification usually takes 1–3 weeks and directly affects the start time. Is there a Service ID and token?
2. SalesDrive API — is access confirmed for reading orders with products + updating amounts/adding items + setting tags?
3. The description cuts off at step 9 (“...about the necessity of inspection”) — please send the full text of the technical specification to consider all branches of the scenario in the assessment.

What is included in the price: web panel for the manager (orders/scenarios/leaflets), integration of SalesDrive API, Viber Business Messages API (webhook, dialog status, buttons), AI text recognition of the client and matching with the products in the leaflets, admin panel for leaflets/catalog, deployment on your server.

Cost: 15,000 UAH, duration 3 weeks — after confirmation of access and final technical specification. Payment through Safe. Expand

Hello!
We are the Business Atlas team, official partners of n8n. The task of automating confirmations and AI upselling via Viber for SalesDrive is very familiar to us — we know how to create such systems to automatically increase the average check and free up managers' time.
The essence of your project relies on three critical nodes:
The first — a two-way low-code integration. Building a workflow based on n8n/Make to combine the SalesDrive API, TurboSMS API, and Viber chat sessions. This will ensure stable data exchange, history tracking, and system operation without overpaying for expensive code.
The second — AI text parsing and CRM update. Connecting OpenAI/Claude API for analyzing the client's free text. The neural network will accurately match requests with items from the sent flyers, autonomously adding positions in SalesDrive and recalculating the amount.
The third — web panel and "Stop-bot" logic. Setting up a user-friendly interface for order selection and flyer management, as well as instant transfer of the dialogue to the manager in any non-standard situations (voice, photo, operator request, or AI error).
My experience as a project manager and my team's experience are focused specifically on low-code architecture and data automation. We have implemented over 50 projects in the UA/EU markets. We have direct relevant experience: we implemented SalesDrive for a cosmetics store, created WhatsApp AI managers for full application management with upselling, and set up transactional mailings. As n8n partners, we deploy self-hosted solutions on your VPS, ensuring maximum speed for processing webhooks from TurboSMS and system operation without monthly subscription fees for limits.
Conditions and answers to questions:
1. Experience with CRM/API/webhooks and AI: Yes, this is our main specialization (we have ready cases of AI agents and integrations with SalesDrive).
2. MVP timelines: Approximately 3–5 weeks of work.
3. Cost: A fixed estimate will be provided immediately after expert diagnostics and studying your detailed specifications to guarantee results without hidden payments.
4. Support: The cost includes 2 weeks of free warranty support for bug fixes.
Message me privately — send the complete specifications, and we will agree on a time for a short call! Expand

Good day, I see that this is not just a chatbot, but a complex chain: SalesDrive, Viber, webhooks, dialogue states, and AI text recognition. I can design an MVP so that the scenarios are managed from the admin panel, and non-standard cases are correctly passed to the manager. I have 8 years in web development and experience with API/webhook integrations. To assess the exact architecture and timelines, please send the technical specifications — I will quickly prepare an implementation plan.

Budget: 8000 UAH Deadline: 10 days

Hello! At BotCraft Group, we are currently working on such automations — Viber/Telegram bots with CRM integration and free text recognition through AI, so your scenario is close to our turnkey solution.

Here’s how I see the implementation:
- Web manager panel: selection of orders from SalesDrive, selection of scenarios and postcards, launching the processing.
- Viber Business Messages: transactional message with order data + buttons, the entire step-by-step flow of confirmations (items 2-10) with editable admin templates.
- AI module: analyzes the client's free text and matches positions only with products from the sent postcards (based on the saved list of IDs/articles), forms a list for confirmation.
- Two-way integration with SalesDrive: additional orders are added to the existing order, the amount and status are updated, and a "quick dispatch" mark is saved.
- Non-standard cases — for the manager.

I suggest starting with a working MVP of the main flow (confirmation + SalesDrive), then connecting AI recognition of postcards — this way you can see the results step by step.

The price is 8000 UAH — I am taking it at the starting rate, gathering initial reviews on Freelancehunt, so I am offering a good deal. The working MVP timeline is approximately 7-10 days.

One clarification: do you already have Viber Business connected (official account for Business Messages) and is there access to the SalesDrive API for order recording? This affects the start of the integration.

There are live demo bots — I am ready to show the flow in the chat right away, so you can try it yourself.

Good day! I develop in Python, React/Node.js. I have extensive experience in the field and am ready for collaboration.

Budget: 27000 UAH Deadline: 18 days

Hello! The project is formulated extremely competently and logically. I have extensive experience in developing custom web applications, integrating CRM systems, APIs/Webhooks, and implementing LLM (AI) for data structuring.

I am ready to implement this web application for you on the stack of Laravel + FilamentPHP + PostgreSQL/MySQL.

Here’s how the architecture of the solution will be built:

1. State Machine and scenario processing:
- Each Viber chat will have a clearly defined state. In the event of non-standard situations, unknown attachments, or recognition errors, the scenario will immediately stop and transfer control to the manager.

2. Working with AI (LLM API):
- To recognize the client's text, we will use a model with the Structured Outputs (JSON Schema) parameter. The AI will receive context only from the currently selected postcards, which eliminates hallucinations and guarantees accurate matching by ID/articles.

3. Integrations (SalesDrive & TurboSMS):
- Asynchronous processing of webhooks from TurboSMS through queues to avoid message loss during peak loads.
- Bidirectional exchange with SalesDrive API: reading orders, updating stock/amount, adding comments, and changing statuses.

4. Manager web panel on FilamentPHP:
- Fast and modern UI with convenient bulk actions for selecting orders and linking postcards.
- User-friendly modal windows with a complete log of the Viber dialogue and statistics widgets.

Answers to your questions:
1. Estimated cost of MVP: $1,200 - $1,500 (depending on the final details of the specifications).
2. Estimated timeframe: 14-18 working days.
3. Experience with CRM/API/webhook integrations: regular development of API modules, working with SalesDrive, TurboSMS, REST API.
4. Experience with AI/LLM API: developing prompt scenarios and parsers of free text into fixed JSON structures via Gemini/OpenAI API.
5. Examples of similar backend systems and integrations can be provided during the discussion.

Hello!

This is an interesting task involving business process automation using CRM, Viber Business Messages, and AI. I have experience in developing complex web applications using Node.js and React, integrating third-party APIs, webhooks, payment and CRM systems, as well as implementing services using LLM for processing user data.

For implementation, I propose the following stack:
Backend: Node.js (NestJS), TypeScript;
Frontend: React/Next.js;
Database: PostgreSQL;
Task queues: Redis + BullMQ;
AI: OpenAI API or another LLM with the ability to switch providers;
Deployment: Docker.

I can implement:
* a web manager panel with order selection, scenarios, and promotional messages;
* integration with SalesDrive API;
* integration with TurboSMS HTTP API and webhook for Viber Business Messages;
* storage of dialogue states and message history;
* automatic status changes and order composition in CRM;
* handling of non-standard situations with order transfer to the manager;
* an administrative panel for managing scenarios, messages, products, and message templates;
* basic analytics and order processing logs.

When working with AI, the architecture will be designed in such a way that the model can be replaced without reworking the entire system. Structured prompts and result validation will be used for text recognition before making changes to orders, which will help reduce errors and make the system's operation more predictable.

Preliminary estimate:
MVP: from 2,000 USD (after reviewing the full technical specification, I will provide an accurate estimate);
Development time: 4-6 weeks.

I have experience in:
* integrating REST APIs, webhooks, and third-party services;
* developing business process automation systems;
* integrating AI/LLM APIs for processing user text and automating scenarios.

I look forward to reviewing the complete technical task, after which I will prepare a detailed implementation plan, break the project into stages, and provide an accurate cost and timeline estimate. Expand

Budget: 20000 UAH Deadline: 21 days

Hello! The task is clear: we need to connect SalesDrive, Viber Business Messages, and AI analysis into a single scenario with a web panel for managers.

I have 3.5 years of commercial experience in fullstack development (TypeScript, NestJS, Vue/Nuxt, PostgreSQL). I have worked on B2B products with similar logic: data exchange between external APIs, automation of order processing, real-time status and amount updates. All of this fits perfectly with your case.

In terms of architecture, I see it like this: a NestJS backend with webhooks from Viber, integration with the SalesDrive API for reading and updating orders, and LLM for matching free text from the client with products from brochures. A web interface on Vue/Nuxt for managers with real-time dialogue monitoring.

I am ready to discuss the details and timelines.

Budget: 26000 UAH Deadline: 20 days

Hello, Valentin!

1. I understand that the maximum budget for the project is 27,000 UAH. Considering the scope (webhook integration, dialogue state, AI matching, admin panel), it is realistic to cover the main scenario (items 1-9) within this amount without part of the statistics/UI polishing - I suggest discussing the exact set after the technical specifications. I set the budget at 26,000 UAH.

2. Deadline: about 20 days from the moment of receiving the full technical specifications.

3. Experience with CRM/API/webhook: I built an event-driven pipeline with queues/workers and async processing (edrsr-ai-server), webhook alerts via Telegram Bot API in a travel aggregator with full CI/CD (fasttravel), FastAPI backend wrapping the external marketplace API (Prom.ua) with batch processing, queue, and progress statuses (promAI). I do not have direct experience with SalesDrive and Viber Business Messages, but the working model (webhook → dialogue state → CRM update) is the same as I have already implemented on other APIs.

4. Experience with AI/LLM for free text: promAI uses Gemini API with structured outputs and result validation - exactly the pattern needed for matching client messages with the product list of the flyer. Additionally, there is a RAG bot (youtube_helper) with hybrid vector+keyword retrieval and MMR selection of context for matching text with the database.

5. Examples (public repositories): github.com/slonce70/promAI, github.com/slonce70/youtube_helper, github.com/slonce70/fasttravel. I can show private repositories during a call. Expand

Budget: 10000 UAH Deadline: 7 days

Ready to take on the development of a web application for automating order confirmations and upselling through Viber with integration of SalesDrive, TurboSMS (Viber Business Messages), and AI for parsing free text from the client.

1. Estimated cost for MVP: $4,500 – $7,000 (fixed after reviewing the full technical specification and access to SalesDrive / TurboSMS API). In the MVP: web manager panel, selection of orders/scenarios/flyers, complete scenario 1–11, FSM dialogue, admin panel for flyers and contacts, logs/history, basic statistics, transfer of non-standard cases to the manager.

2. Timeline: 4–6 weeks until a working MVP on staging + assistance with the first launch. 1–2 days for auditing the technical specification and API → integrations and FSM → manager panel → AI recognition based on the flyer catalog → scenario tests and handoff to the manager.

3. Experience with CRM/API/webhook: yes. Integrated external CRMs and messenger gateways via REST/HTTP API, webhook for incoming responses, idempotency, retries on failures, storage of dialogue state and order statuses. I include SalesDrive and TurboSMS in the same manner: a separate adapter for each API, the core of the scenario is independent of the channel.

4. Experience with AI/LLM: yes. Parsed free text through LLM API (function calling / structured output): matching client formulations with a closed list of products and IDs/articles, output JSON "product + quantity," repetition in case of ambiguity, no invented items outside the flyer catalog. I do not process voice/photos/files — only text, as specified in the technical specification.

5. Similar projects: AI assistants and bots with FSM scenarios, user data confirmation, and recording results in an external system; automation of dialogues in messengers (Telegram/Viber-like webhook streams); admin panels for operators with entity selection, chat history, and escalation to the manager. Details and screenshots available upon request after NDA / during a call.

Architecturally: backend (Python FastAPI or Node.js) + PostgreSQL + Docker; FSM by scenario steps; adapters for SalesDrive / TurboSMS / LLM; web manager panel. Non-standard cases stop the auto-scenario and transfer the order to the manager with the dialogue history.

For an accurate estimate, a complete technical specification, test access to SalesDrive and TurboSMS, and examples of flyers with product structure are needed. I can start with a technical plan and dialogue state diagram. Expand

Hello! I have experience in web programming and automating dialogues with clients. I would be happy to help you.

Budget: 25000 UAH Deadline: 30 days

Hello!
I see that you need not just a Viber bot, but a fully managed order confirmation process with AI text recognition, integration with SalesDrive, and automatic upselling without burdening the managers. The key here is reliable management of dialogue states so that the script works correctly even with multiple messages from the client.

I specialize in developing AI automations and integrations through API, CRM, and webhook. I have created systems that combine CRM, AI, and automated communication scripts, as well as implemented AI for analyzing user messages and automating business processes. My experience includes Make.com, ChatGPT, Claude, Voiceflow, CRM integrations, and building multi-step workflows.

I would suggest building the system as a separate backend with a manager web panel, a SalesDrive integration module, TurboSMS/Viber, an AI service for product recognition, and a separate module for managing dialogue states. Such architecture will significantly simplify scaling and adding new scenarios in the future.

Preliminary:
• MVP — from $1,500–2,500 depending on the details of the technical specification.

Hello! The categories are indicated absolutely correctly — the project requires deep development of both server logic (for managing dialog states) and a web interface for managers. I have reviewed the specifications, and the task is very clear, logical, and interesting. I have extensive experience in developing asynchronous backend systems, integrating third-party APIs, and automating business processes.

Here are specific answers to your questions:
1. Estimated cost of developing the MVP:
35,000 – 45,000 UAH. We will finalize the exact figure after reviewing the full specifications and agreeing on the architecture (for example, choosing a specific LLM model).
2. Estimated development time:
14–20 days (considering the stages of thorough testing of edge-case situations: when the client writes nonsense, sends empty messages, or tries to break the calculator).
3. Experience in integrating with CRM / API / webhooks:
Expert. I regularly design systems that operate on asynchronous webhooks under high load. I can implement integrations with SalesDrive API and TurboSMS HTTP API without issues, with clear logging of requests to ensure no order or status is lost.
4. Experience in integrating AI / LLM API for text processing:
I have successful experience working with OpenAI API (GPT-4o / GPT-4o-mini) and Anthropic. For your task (point 5), the Function Calling (Structured Outputs) technology is ideal. We feed the AI a prompt, the current text from the client, and a structured array of products from the selected card, and we are guaranteed to receive a clean JSON object with the product ID and quantity, minimizing the hallucinations of the neural network.
5. Examples of similar projects:
I have developed custom administrative web panels (Dashboards) for data monitoring, asynchronous dialog systems with complex state preservation (FSM) in the database, as well as automated scripts for business.

How I see the architecture of the MVP:
Backend/Web panel: Python (FastAPI or Django) + PostgreSQL for storing dialog states, history, and administration. The platform is ideal for fast and stable processing of webhooks and AI.
Deployment: I fully containerize the project in Docker for stable operation on your VPS.

I am ready to review the detailed specifications, discuss the architecture in chat, and start working through a secure Safe. Looking forward to hearing from you! Expand

LLM for analyzing customer text with a fallback to a manager in case of uncertainty. I will separately work on the scenario where recognition is limited only to products from sent postcards and quantity validation is needed. If you are ready, please send the technical specifications and examples of postcards or test access to SalesDrive, then I will return specific questions and an accurate estimate. API and webhook in online store projects, as well as AI integrations. Good day. I can take on the implementation of this web application and already see key risks in the process. The main thing for you is a reliable binding of the Viber session to a specific order in SalesDrive and correct processing of the webhook with a guarantee of idempotency of messages. I will provide an approximate cost for the MVP and timelines after reviewing the detailed technical task. I have practical experience in CRM integrations.

Budget: 27000 UAH Deadline: 21 days

Hello! Yes, implementing this scenario is absolutely feasible. This is a classic state machine task (dialogue state management) with integration of external APIs and LLM through Tool Calling (Function Calling) for structuring text in JSON. I have extensive experience in developing autonomous AI agents, complex integrations, and micro-SaaS systems. The ideal stack for this project would be: Python (FastAPI) for resilient webhook and queue processing + React/Next.js for the manager's web panel.

Answers to your questions:
Experience with CRM/API/webhooks: I constantly work with REST APIs, webhooks, and integration of third-party systems. I will quickly deploy a webhook endpoint for TurboSMS that will instantly capture customer responses, identify their user_id, and match it with the current order status in SalesDrive.

Experience with AI/LLM API: This is my main profile. For product matching, I use structured output (Structured Outputs / JSON Mode) through model APIs (for example, OpenAI GPT-4o-mini or Claude 3.5 Haiku). The AI will receive a strictly limited array of products from the selected leaflet (ID and names) and free text from the customer. As a result, we will guarantee a clean JSON output like [{product_id: 123, quantity: 2}].

MVP logic: We will implement a reliable state machine based on Redis/PostgreSQL. If the customer clicks "Contact Manager" or the AI shows low confidence (confidence score) during recognition, the script will instantly stop, and an alert will be sent to the manager in SalesDrive and the web panel.

Commercial proposal (MVP):
Estimated cost: $1,800 – $2,400 USD (depends on the final specifications and the number of scenarios).
Estimated timeframe: 3–4 weeks.
What’s included: Manager's web panel (management of leaflets/products, order selection), backend automation, integration of SalesDrive API, TurboSMS (Viber Business), linking LLM for text parsing, and logic for transferring the dialogue to a human.

Example of similar experience: I have developed complex multi-step AI assistants with integration of messengers, CRM, and external APIs, where it is critically important to maintain the context of the conversation, handle timeouts, and automate follow-up scenarios.

You can familiarize yourself with my engineering approach on the website: https://mcarrow.online. I am ready to review your detailed specifications, discuss the nuances of the SalesDrive and TurboSMS APIs, and start the project architecture!

Good day, Valentyn.

Your system will automatically confirm orders and suggest additional products via Viber, reducing the workload on managers. Integration with SalesDrive through API will allow real-time order updates, and AI will accurately recognize the customer's choice from postcards. Using TurboSMS for Viber Business Messages will ensure reliable message delivery. The web panel on React will enable management of scenarios, postcards, and tracking statistics. The solution will be deployed in Docker for easy scaling. All non-standard situations will be automatically forwarded to the manager, preserving the complete dialogue history.

Hello, Valentin! I carefully studied the description of your business process for automating Viber dialogues. The task is fully feasible. I am ready to develop a stable MVP for you in Python 3.12 with integration of SalesDrive, TurboSMS, and an AI model for recognizing upsells.

I have extensive experience working with APIs, webhooks, and LLM for parsing free text. Here’s how I will implement the key nodes of your system:

1. State machine script engine (FSM): Each dialogue will remember its step. If the client clicks "Contact the manager" or the AI cannot recognize the text, the bot will instantly stop the automation and transfer the order to a human, avoiding sending unnecessary messages.
2. AI matching without hallucinations: It is not necessary to pass the entire catalog to the AI. Only a structured list of IDs/articles from the selected flyers will be strictly passed to the system prompt for the OpenAI/Claude API. The model will act as a strict parser (extracting entities: product + quantity) and will verify them against the data array.
3. Optimization of Viber sessions: There is a nuance in Viber Business Messages — the automatic sending of several messages in a row (steps 8, 9, 10) may hit session limits if the client does not respond for a long time. I will combine informational blocks or set up logical triggers to ensure messages are delivered and do not expire.
4. Manager web panel: I will create a lightweight, fast, and responsive web interface for selecting orders from SalesDrive, linking articles to flyers, and viewing dialogue history.

The entire architecture will be deployed on reliable Railway hosting with secure storage of tokens in .env files.

Please let me know if you already have a verified Viber Business Messages account in TurboSMS and if access to the SalesDrive API for writing and updating positions in orders has been obtained? Expand

Good day!

I carefully studied the description - the task is clear.
1. I have experience with CRM/API/webhook integrations - I worked with SalesDrive, various APIs, and webhooks.

2. I have experience integrating AI/LLM APIs - I worked with OpenAI and Claude API for recognizing user free text.

3. I have experience developing similar automation scenarios with multi-step dialogues and state storage through a database.

I am ready to review the detailed technical specifications and discuss the details.

Hello!

The project is clear and looks interesting. I have experience in developing CRM integrations, working with REST APIs, webhooks, processing queues, as well as integrating AI/LLM for analyzing user text and automating business processes.

For such a project, I would suggest a stack of Laravel 12 + MySQL + Redis (queues) + AI model API (OpenAI or another LLM) + a separate admin web panel. This architecture will allow for easy scaling of the system, adding new scenarios, and connecting other CRMs or communication channels if necessary.

Preliminary MVP estimate:

Cost: approximately 3,500–6,000 USD (I can provide a precise estimate after reviewing the full specifications).
Timeline: 6–10 weeks, depending on the volume of scenarios and integration details.

Experience:
✅ Integrations with CRMs, REST APIs, webhooks, payment systems, and third-party services.
✅ Development of systems with queue processing and asynchronous processes.
✅ Integration of AI/LLM APIs for analyzing free text, classification, and automating data processing.
I can provide examples of similar projects and integrations in personal correspondence.

I would like to clarify a few questions:
1) Is support for multiple managers with access rights differentiation planned?
2) Should the system handle several thousand active Viber dialogues simultaneously, or is a lower load expected for the MVP?
3) Is a log of all actions (audit) needed, and is there a possibility to restart a scenario for an order?
4) Have you already decided on the AI provider (OpenAI, Claude, Gemini, etc.), or can the solution be chosen during the development process?

I would be happy to review the full specifications and propose an optimal project architecture considering future scaling. Expand

Hello! The key point here is the connection between AI and flyers: to ensure that the model doesn't invent products, I perform recognition with a strict tie to your list of items, first matching by ID and name, and the model only processes free text and quantities. I assemble the dialogue as a finite state machine, where each order remembers its current step, so after handing it over to the manager, the script is clean, without duplicate messages. I also keep in mind the Viber session window in TurboSMS: if the client is silent and it closes, I catch that instead of sending into the void. I will outline the stages and potential pitfalls for free in private. I look forward to collaborating.

Valentin, the scenario has gone through the steps, and under Viber Business Messages via TurboSMS, there is a moment that is not yet in the technical specification.

In one chat session, Viber cuts off the sixth message in a row without a client response, with a limit of five. Your steps 8, 9, and 10 (sending deadlines, package inspection, contacts) go automatically one after another without buttons, and there are also leaflets before them. In a long scenario, the tail simply won't reach, and part of the messages will silently burn with an error. This means the auto-sequence needs to be cut, and part should be tied to the client's action, rather than sending in bulk. Plus, the session lasts 24 hours from the last client message: if a person confirmed and left, but adds products the next day, gathering text (steps 4-6) in the same session can no longer continue. This is a separate state in point 11, do not confuse it with refusal.

The second point is financial, just so you can budget before starting: leaflets with additional products are advertising traffic, for which a separate Viber sender is needed in TurboSMS, and this starts from ~8400 UAH/month minimum. Transactional confirmations are cheaper with a general sender.

I have experience with CRM/API/webhook integrations and connecting LLM for parsing free text. I will assemble an MVP: synchronous SalesDrive, scenario engine based on states, matching client text with leaflet products by articles, manager panel, history, statistics. Approximately 15-18k for the MVP and about two weeks after the full technical specification and access, I will provide an exact range when I review the technical specification. The profile here is new, so the bids are lower: I am currently more interested in the first review. We work through Safe.

Is your own Viber sender in TurboSMS already set up, or should we also include it in the scope and budget?

The logic is clear: SalesDrive API — order synchronization, TurboSMS webhook — receiving/sending Viber messages, AI matches the client's text with the list of products in the flyer by ID/articles. I have experience with CRM/webhook integrations and LLM text processing, I will show similar cases. Cost and timeline — in the bid, approximately 4 days for the prototype.
