Sell your Shopify products on Poland's largest marketplace — 20M+ active buyers, automated syncing
Allegro is the undisputed leader of Polish e-commerce, commanding over 35% of the market and serving more than 20 million active buyers — a scale that dwarfs Amazon's presence in the country. For Shopify merchants looking to expand into Central and Eastern Europe, Allegro is not just an option, it is the channel that defines online shopping in Poland. This page walks through exactly how to connect Shopify to Allegro, what selling in Poland requires, and how Marqetir removes the two biggest barriers cross-border sellers face: Polish-language listings and Allegro's category-specific commission structure. For broader market context, see our complete Allegro seller guide.
The connection itself is straightforward on the Shopify side. You install the Marqetir app from the Shopify App Store and authorise it via OAuth to read your products and orders — no API keys to copy, no developer setup. On the Allegro side, you link your seller account through a secure OAuth flow. From there, Marqetir pushes your Shopify catalog into Allegro, mapping each product to the correct Allegro category and required attributes. Because Allegro's taxonomy and attribute requirements differ sharply from a typical Shopify store, this mapping step is where most manual integrations stall — and where Marqetir's AI category mapper does the heavy lifting automatically.
Language is the decisive factor on Allegro. Listings must be in Polish, and Polish buyers can tell machine translation from native copy instantly — poor translations tank both conversion and search ranking. Marqetir generates native-quality Polish titles and descriptions optimised for how Polish shoppers actually search, which differs meaningfully from Western search behaviour. This is the difference between a listing that surfaces in Allegro's results and one that never gets seen. The integration also handles the financial side: your Shopify prices convert to Polish złoty (PLN) automatically, with configurable margin rules so currency conversion never silently erodes your profit.
Allegro's fee model is genuinely seller-friendly, which is part of why it rewards getting on the platform early. There is no monthly subscription — you pay only when you sell. Commission (prowizja) is charged by category, ranging from about 5.54% for electronics up to roughly 14% for jewellery, with most categories landing between 9% and 13%. On top of that sits a flat 1.3% payment processing fee through Allegro Pay. That is the whole cost structure — no hidden per-item fees. Because electronics carry the lowest commission, high-value tech can be very profitable here; model your specific categories against the numbers on our Allegro fees page before you list.
Once you are live, Marqetir keeps Shopify as your operational hub. Inventory syncs in real time, so a sale on either platform updates stock on both within seconds and prevents overselling. Allegro orders import automatically into your Shopify admin as new orders, so your team fulfils them through the exact workflow they already know, and tracking numbers sync back to Allegro automatically. If you participate in Allegro Smart! — Allegro's free-delivery loyalty programme that can lift conversion by up to 30% — Marqetir supports the fulfilment requirements while you keep managing everything from one Shopify dashboard.
