Budget: 25000 EUR Deadline: 21 days

We can approach this as the !!first technical stage!! - Shopify - Allegro, inventory, currencies, language fields, Allegro's requirements for product cards, and preparation of the scheme for the next European marketplaces =)

Regarding the timeline - approximately 21 days for catalog audit, exchange scheme, launching the first stable export, and checking inventory updates. The estimate for the first stage is 65,000 UAH, and further regular participation should be calculated separately after the volume of the catalog and the number of manual exceptions become clear.

We have worked with e-commerce, product processes, integrations, and admin panels, where not only product cards are important, but also data stability, money, and responsibility for errors. At the start, I would not reduce this to manual product transfer - a proper category model, attribute mapping, translations, currency control, error log, and a clear process for the warehouse in Slovakia are needed. This is necessary to ensure that regular work does not turn into an endless manual routine.

> What is the volume of the catalog - the number of products, variations, and whether there are different warehouses?
> Is it necessary to add the Polish language in Shopify, or is a separate prepared feed for Allegro sufficient?

Launching a Shopify store on the Polish Allegro with inventory synchronization, adding the Polish language, and setting up currencies is a task that requires knowledge of both platforms and an understanding of the middleware between them. I have over 8 years of experience with e-commerce integrations, including marketplace connections, catalog synchronization, multilingual support, and multi-currency — exactly the stack of tasks you have.

Here’s how I see the implementation:

Shopify → Allegro Integration: There is no official integration in the Shopify App Store; the connection requires a third-party tool. The optimal option is BaseLinker or Koongo:
BaseLinker allows you to integrate Shopify with Allegro, Amazon, eBay, and other marketplaces so that products appear simultaneously on different sales channels. This covers catalog, inventory, order, and price synchronization. An alternative — Koongo synchronizes product, inventory, and price data automatically on each connected marketplace.
Polish Language: I will add Polish translation in Shopify (Shopify Markets / Translate & Adapt or Weglot), and for Allegro — translation of listings through BaseLinker or a separate workflow.
Currencies: Setting up PLN through Shopify Markets + correct display of prices in zlotys on Allegro.
Inventory: When a customer purchases a product on Allegro, the integration system automatically reduces the stock quantity in Shopify and vice versa — this prevents overselling.
Scaling: The architecture through BaseLinker/Koongo will allow connecting other European marketplaces (Amazon DE/PL, eBay, Kaufland) without reworking.

Hello. The main thing here is not just to "export to Google Sheets," but to ensure that the data can be trusted: schedule, clear fields, protection against duplicates, and proper error diagnostics.

Here’s how I would approach it:
1. First, I will fix the structure of the indicators: which KPIs, where we take them from 1C/BAS, and into which cells/sheets we place them.
2. I will create a separate layer for data exchange with the Google Sheets API: scheduled updates, checking for empty/broken data, logging.
3. If two-way exchange is needed, I will separately secure the script for writing back to avoid accidentally corrupting the data in the database.
4. In the end, I will leave clear instructions: where to change the schedule, how to check the last run, what to do in case of an error.

I have experience with automation/API pipelines and systems where business data must reliably flow into Telegram/tables/CRM without manual hassle.
Regarding timelines: the target is 7 days. As for the budget: 18,000 — after a brief clarification of the technical specifications, I will confirm, but that’s the range.

Good day, Oleksandr!

I can help with the integration of the Shopify store with Allegro and further scaling to other European marketplaces.

I work with Shopify, API integrations, and ecommerce automation, so I can take on both the technical setup and the operational part of synchronizing products, stock, currencies, and localization.

What I can implement:
— Shopify ↔ Allegro integration
— Stock and price synchronization
— Proper functioning of currencies and languages
