Development of a turnkey e-commerce platform for auto parts CarLeo (OpenCart)

Budget: 27000 UAH Deadline: 10 days

30 days and 40,000 UAH for the entire technical specification is not a realistic estimate. For that money, I wouldn't promise a complete platform with 5 suppliers, Redis or Elasticsearch, VIN, PRRO, Order API, B2B, ATS, CRM modules, and warranty support. Overall, it's reasonable to start with this budget, but as an engineering phase - API audit, architecture, data schema, prototype of the key scenario, and release plan.

My rate here is 27,000 UAH for the first phase over 10 days. The result will be technical architecture, breakdown into releases, verification of supplier APIs, a prototype for searching by article with normalization, a decision on Redis or Elasticsearch, a map of integrations for Nova Poshta, payment, PRRO, notifications, and CRM. After this, we can calculate development more accurately and not gamble with a million-item catalog.

There is an important nuance regarding OpenCart. The technical specification correctly states that transit goods cannot be written in oc_product. For such a catalog, I would create a separate layer for indexing and caching, while leaving the storefront, orders, customers, payments, and management in OpenCart. Otherwise, the site will crash just when the advertising starts working =/

Questions that make it risky to calculate more accurately:
> Are there already test accesses or documentation for the APIs of Elit, Omega-Autopostavka, Avtonova-D, Inter Cars, Vladislav, including Order API?
> Which modules should be included in the first working release - just the storefront, search, cart, payment, Nova Poshta, and 1-2 suppliers, or also the B2B cabinet, PRRO, ATS, and notifications?

If we proceed further within the marketplace, I would start with brief design and technical prototyping. Measure seven times - cut once; here, it's not wisdom for a poster, but a budget-saving strategy. Expand

Hello! I am ready to take on the project and support. Opencart is 100% suitable.
Message me privately to discuss the details!
Have a great day!

Budget: 27000 UAH Deadline: 30 days

Good day!

Thank you for the detailed specifications; I have read all 15 points. The scope is impressive, but I must be honest: the described functionality (5 supplier APIs with Redis/Elasticsearch caching, Laximo/AutoXP catalogs, AI VIN decoder, PRRO, Nova Poshta with auto dropshipping, cloud PBX, full-fledged CRM, B2B cabinet, brand/mascot development, SEO infrastructure) represents the scope of an enterprise project, which realistically requires several months of team work, not just one developer in 30 days. The budget of 40,000 UAH for 2 stages, unfortunately, does not correspond to the stated scope even approximately; it is more like the cost of an MVP version with very limited functionality.

I would like to draw attention to point 4.3: integration with the "API of the Ministry of Internal Affairs of Ukraine databases" for identifying vehicles by registration number; as far as I know, such a public/commercial API does not exist.

I propose two options for further action:
A realistic assessment of the full scope, if the budget is negotiable, I am ready to provide an honest estimate of the cost and timelines for the entire specifications.

MVP under the stated budget, we determine the priority minimum (for example: catalog + search by article + integration of 1-2 suppliers + cart + payment + basic admin panel), and the rest of the functionality (VIN/AI decoder, CRM, PBX, B2B cabinet, branding) is moved to subsequent stages with a separate budget. I am ready to discuss which option is closer to you.

Budget: 27000 UAH Deadline: 10 days

Hello!

I have carefully reviewed the description of CarLeo. It is not just a standard store on OpenCart, but a full-fledged e-commerce system with a large catalog, online pricing, supplier integrations, a B2B cabinet, and automation for managers.

My main focus is on developing complex web systems, CRMs, API integrations, and server infrastructure. I work with Python, Django, REST API, PostgreSQL, Redis, Docker, search engines, and external services. I have implemented over 30 projects, including CRM solutions for medical and retail businesses, platforms for automating internal processes, and AI integrations.

For your project, I would suggest not overloading OpenCart directly with all the complex logic. The optimal architecture would be:

— OpenCart as CMS, storefront, cart, orders, and administrative part;
— a separate integration module for working with supplier APIs;
— queues and caching for updating prices and stock without blocking the site;
— Redis for caching and Elasticsearch/OpenSearch for fast searching through a million-item catalog;
— centralized normalization of articles, analogs, and cross-references;
— logging of API errors and automatic retries;
— separate pricing rules for B2C, service stations, and other B2B clients.

I would pay special attention to search. Articles, names, VINs, and license plates should not be processed with a single primitive SQL query. Different search scenarios are needed, normalization of input, removal of spaces and special characters, handling of cross-references, and clear ranking of results.

I can also implement and combine:

— supplier APIs and stock synchronization;
— Nova Poshta, automatic creation of shipping documents, and dropshipping;
— LiqPay, WayForPay, or MonoPay;
— Checkbox or Vchysno;
— Telegram, Viber, SMS, and email notifications;
— B2B cabinet for service stations;
— CRM interface for managers;
— multilingual support UA/RU/EN;
— responsive Mobile-First interface;
— server deployment, backup, monitoring, and protection.

I want to be upfront: my main stack is Python/Django, not exclusively OpenCart. However, for such a project, a strong separate backend architecture is an advantage, as critical integrations, search, and online pricing are risky to build solely on standard CMS modules.

Before starting work, I suggest separately checking the API documentation of each supplier, request limits, cross-reference formats, stock update frequency, and the availability of VIN/license plate services. After that, a reliable architecture can be established without dependence on unstable third-party modules.

I am ready to discuss the technical task in detail. Expand

Budget: 27000 UAH Deadline: 5 days

Real-time stocks and leftovers from Elit and Avtonova-D, without cache (Redis), each search hits suppliers directly and the site will slow down under load.

In the first stage, I will create the OpenCart structure, a Mobile-First layout with bottom navigation, search by article and VIN with ISO 3779 validation, connect the stock of one supplier, Nova Poshta, and LiqPay.

Is it realistic to raise all 5 suppliers at once under 27,000, or should I start with 1-2 and expand in the second stage? The first cut is ready to show in 5 days.

Budget: 27000 UAH Deadline: 14 days

Hello. I am suitable for this project as an OpenCart specialist, with practical experience in launching large B2C/B2B stores and providing ongoing technical support.

A critical point for the correct functioning of the catalog is the normalization of articles and strict validation of VIN according to ISO 3779 standards, which affects the substitution of cross-references and online assessment.

Can you provide test access or examples of supplier API responses and an export of the catalog with the expected number of articles? After that, I will send examples of completed OpenCart projects with a brief description of my role in them and propose the first specific steps. I am ready for long-term support.

Budget: 27000 UAH Deadline: 16 days

I have experience in developing large online stores on OpenCart with supplier integrations and B2B cabinets. It is critical to ensure correct normalization of articles and strict validation of VIN according to ISO 3779, as this directly affects the accuracy of matching and cross-matching. I am ready to review your technical specifications, clarify access to supplier APIs, and after that, send relevant examples of my work. I am interested in long-term technical support for the project. Is it convenient to discuss access to the technical specifications and the list of suppliers in a brief correspondence or call?

Budget: 27000 UAH Deadline: 30 days

Good day, I have been developing and maintaining websites on OpenCart for over 15 years. I am ready to carry out your tasks.
