Building a custom CRM system for e-commerce

Good day.

20 years of development experience, including Web FullStack.
Also, I have been working with marketplaces for 8 years: Rozetka (I also sell there), Prom, Kasta, etc.
Various automation, exports, synchronizations.
Therefore, I know all the nuances of Rozetka, Prom, etc., all the pain points of sellers on these platforms.
I also have experience in developing CRM/ERP systems.

Of course, I have experience with API/webhooks integrations, experience with AI integration, telephony, other services with different exchange formats, and much more.
…
I also suggest not to strictly tie it only to Rozetka.
We can create a multi-platform for marketplaces and then gradually integrate others.
That is, statuses from different marketplaces will be taken into account, and triggers will work correctly.

I will do everything based on Laravel.
Any integrations via API, statuses, triggers, creating tasks for the manager to call back, etc.
That is, auto-creation of tasks for the manager based on a trigger - this will be a very important feature for convenience and efficiency.
Configurator for triggers.
In general, there are many ideas; we need to discuss what to do for the MVP and what can be left for later.

An important section is Suppliers, Warehouse.
That is, the source of offers from which we form product cards.
Automation for suppliers, processing different formats, etc.
There is a lot here; I have been closely involved in this for 8 years, so I have a lot of developments and experience.
And then the Production module will also be needed. I have such a powerful module currently in development. I will tell you more about it.

I also have experience in building high-load systems so that hundreds of thousands of products can easily "rotate" in the system and everything works quickly and smoothly.
Database design and optimized queries from the UI.

I will show my CRM/ERP in private messages.
I am also considering a long-term partnership.

Evaluation.
1) Discussion of the technical specifications, clarification of wishes, recommendations.
2) Architecture.
3) MVP.
Price starting from $1500.

"Not taken for 3 days → reminder" - reminder where? Just in Viber or creating a task for the manager with deadlines and performance control?

In the response, the price for point 1 from the Evaluation, so it is convenient to immediately accept the response and start the discussion.

Hello!

I will create a custom CRM system for your marketplace Rozetka from scratch using Laravel + Vue.js: order automation, reduction of unclaimed parcels, communication via Viber, personalization for products, multi-accounts for scaling to other sellers, integration with Rozetka API, Nova Poshta, and Viber Business API, AI module for automatic responses, admin panel with roles, and speed of 95+.

Laravel + Vue.js is better than any ready-made CRM: full control over data and code, zero monthly payments, maximum flexibility for your processes, faster implementation of AI and automation, easy scaling for SaaS without limitations.

We have extensive experience in developing web interfaces and design, so you will receive a stable, user-friendly, and scalable system.

Please write in private messages for details on pricing and timelines!
…
Best regards, Mykola

Hello!
We have relevant experience in developing CRM/ERP systems, particularly with integrations through API, webhooks, order status logic, and communication automation. We also have our own custom CRM system (built on Angular).

It is worth noting that we create AI assistants for specific business processes: automatic responses, trigger messages, communication personalization, response control and confirmation — all within a secure and managed logic.

We take a systematic approach to such projects:
- we start with architecture and design,
- we clearly define the MVP,
- we lay the groundwork for scalability to a SaaS model,
… - we work with our own server / VPS and full data control.

We suggest discussing the details first (integrations with Rozetka, Viber, Nova Poshta, SKU volume, AI logic), after which we can:
- propose the optimal technical stack,
- describe how we envision the MVP,
- formulate a realistic budget by stages and explain what exactly is included in it.

We would be happy to discuss the project in more detail.

Hello! Very well-written project brief.

As a Senior Backend Developer (10+ years of experience, PHP/Laravel + Python), I specialize in creating complex CRM and SaaS systems. I have experience working with the APIs of Rozetka, Nova Poshta, and the architecture of high-load systems.

Regarding the budget and deadlines: $5000 (200,000 UAH) and 60 days. This estimate includes the full implementation of Stage 0 (Architecture) and Stage 1 (MVP CRM). The estimation for the subsequent stages (AI module and Scaling) will be conducted separately after the launch and testing of the MVP.

Technical solution for the MVP:
Stack: Laravel 11 + FilamentPHP. This will save up to 40% of the budget on frontend development of the admin panel while providing a modern, responsive UI and powerful tables/filters "out of the box."
Architecture (SaaS-ready): From the start, I will lay the database structure for Multi-Tenancy. This will allow for the painless integration of other vendors in Stage 3 without rewriting the core of the system.
… Reliability of integrations: Working with APIs (Rozetka, Nova Poshta) will be implemented through queues (Redis). This guarantees that the CRM will not "hang" if the postal API takes a long time to respond, and no order status will be lost.
Triggers: Implementation of a flexible event system (Events). For example: "NP Status 'In the department' for more than 3 days" -> "Automatic sending via Viber."

Why me:
I understand the business logic of e-commerce (non-deliveries, margins, statuses).
I have experience with Python, which will be a critical advantage in Stage 2 when implementing the AI module.
I provide code with complete documentation for further support.
I am ready to start designing the architecture (Stage 0) today.

Good evening!
We can develop a CRM for you, but first please write down the specific functionality of the CRM. The description only mentions AI integration and Viber notifications.
This is necessary for assessment and building the correct architecture.
Feel free to reach out, we will be happy to help.
