Technical specification for the refinement of the OpenCart website

Budget: 10000 UAH Deadline: 10 days

Good day, I am interested in your proposal. I would be happy to collaborate. Cost calculations and timelines will be discussed after the details are clarified.

Good day.
I have experience in developing additional functionality for OpenCart. I can implement all the functionality you need with the help of module development and adding modifiers.
The cost for all the work will be 1700 USD. It can be divided into stages, and each functionality can be paid for separately.

Hello!

I looked at the technical specifications — the task is clear: 1C (clients, personal prices), calculator, stock from several suppliers and TecDoc.

I have worked with OpenCart + 1C, exchange through CommerceML and REST. I have implemented personal prices based on client login. I have also aggregated stock from several suppliers — it is critical to correctly set up the cache and cron to avoid hitting the API on every user request.

Before giving an exact estimate, a couple of questions:

What version of OpenCart is being used, and what configuration of 1C (UT, UNF, other)?
Is there already access to the TecDoc API, or does it need to be obtained?
How many suppliers are there and in what format do they provide data (XML / JSON / SOAP)?
Approximately — 3–4 weeks in stages with testing. After receiving the answers, I will provide an exact price and timeline. Expand

Why I will perform this task best:
I work with OpenCart not as a template CMS, but as a platform for building a stable eCommerce solution. In this project, it is important not just to "connect 1C or API," but to ensure that everything works as a single system without conflicts and overload. I immediately consider the risks: data duplication, synchronization delays, incorrect prices, caching issues, and load problems. My approach is clean code without hacks, extensible logic, and clear separation of modules. I make integrations so that they can be maintained and scaled, rather than rewritten in a month. I pay special attention to personal pricing and authorization logic — this is critical for B2B clients. I also implement the handling of stock from multiple sources correctly, so that the user sees the real picture and can choose a supplier without errors. As a result, you get not a "finished website," but a stable sales tool that is ready for load and development.
Work plan:
Audit of the current state of the website and code:
Designing the architecture of integrations:
Implementation of integration with 1C and synchronization:
Binding clients and logic of personal pricing:
Development of a dynamic calculator:
Integration of supplier APIs:
Combining stock and display logic:
Implementation of supplier selection:
Optimization of updates via cron:
Integration of the TecDoc catalog:
Search by car and binding of products:
Performance optimization:
Testing all scenarios:
Fixing and stabilization:
Final deployment: Expand

Hello.

The project is clear: 1C (clients + personal prices), calculator, integrations with suppliers and TecDoc. Such tasks are better to build as a system right away (API + cron + proper data structure), without "patches" - so that it doesn't break later.

I can handle everything in stages (1C - calculator - stock - TecDoc) with proper synchronization and load. I have experience with OpenCart and integrations, including custom prices and external APIs.

Hello, ready to discuss all the details of the project, we can engage in implementation both from the OpenCart side and from the 1C side. The final cost will be clarified later.

Budget: 27000 UAH Deadline: 20 days

Hello. I have extensive experience with OpenCart. I am ready to collaborate. Please contact me.

Good day
My name is Dmytro
I have reviewed the technical specifications — this is not "just finishing the website," but a proper comprehensive project with integrations, and I can deliver it turnkey
Regarding the approach
I do not create "workarounds," but a stable system: API + cron + proper synchronization logic
It is important that 1C, suppliers, and the website work as a single system without failures
What I will implement
— integration with 1C: clients, personal prices, discounts, automatic synchronization
— account linking and loading individual prices upon login
— price calculator:
dynamic recalculation (client discounts + categories) directly on the product page
— supplier API integration:
stock levels, prices, delivery times
merging warehouses (your + partners)
the ability to choose a supplier before purchase
— TecDoc:
connecting the catalog
search by car / filters / integration with OpenCart products
Important
I will do this with minimal load on the website
with a proper structure for further development
Regarding timelines
3–6 weeks (in stages, as per the technical specifications)
We can work in stages:
1C → calculator → API → TecDoc → testing
I have experience with OpenCart, API, and complex integrations — I will send examples in private messages
I am ready to look at the current website and provide a more accurate estimate
I would be happy to collaborate Expand

Please let me know: do you already have access to 1C (which configuration) and TecDoc, as well as a list of suppliers with their API? And are the discount rules (individual and by categories) approved so that we can immediately lay down the logic of the calculator?

We are a JS+Python team (4 years). We have worked on marketplaces and admin panels with personalized pricing, synchronizations via API/cron, dynamic calculators, and warehouse consolidation. For your OpenCart, we will take: integration of 1C (clients, price types, auto-sync), calculator for individual/category discounts, connection of partner stocks with supplier selection, integration of TecDoc with correct linking to the catalog.

We work in stages (1C → calculator → stocks → TecDoc) with testing at each step. We are ready to start; let’s agree on the details in a short call.
