PrestaShop to Allegro: Publish Your Shop Catalogue as Allegro Offers
For PrestaShop shops in Poland and Central Europe: what Allegro asks of business sellers, how to connect, and which sales FLUF Connect can see.
7 days for £1, then from £9/month.
- Allegro had 20.9 million active buyers at the end of June 2026, 15.6 million of them in Poland.
- You need an Allegro business account to publish offers. A private account will connect but cannot list.
- FLUF Connect reads your PrestaShop catalogue, combinations included, and publishes it as Allegro offers.
- FLUF does not see Allegro sales. When an order comes in on Allegro, mark the item sold in FLUF and it ends the other listings.
This guide is for businesses in Poland, Czechia, Slovakia or Hungary that run a PrestaShop web shop and want their stock on Allegro too. If you sell in Poland, Allegro is where most of your buyers already search, so the question is usually how to run both without double work. If you sell outside Central Europe, Allegro will not move the needle and eBay or Amazon are the better match.
Why Allegro, from a PrestaShop shop
Allegro’s Q2 2026 report puts active buyers at 20.9 million: 15.6 million in its Polish operations and 5.3 million in its international segment. A shop’s own site rarely gets close to that traffic.
The international reach keeps growing. Allegro opened allegro.cz in 2023 and, in a press release of 19 March 2024, announced allegro.sk “niespełna rok po ekspansji na rynek czeski” (less than a year after expanding into Czechia), presenting it as new opportunities for Polish sellers.
What Allegro asks of a business seller
- A business account. FLUF can only publish offers to an Allegro business account. Register it before you connect.
- Product codes. Allegro’s own seller article says GTIN (EAN) is a required parameter in half of its product categories. If your PrestaShop products carry EAN-13 codes, fill them in before listing.
- Free delivery thresholds. Since 2 March 2026, Allegro Smart! gives buyers free delivery on orders of 49,90 zł or more from one seller, whether the parcel goes to a locker, a pickup point or by courier. Price low-value items with that line in mind.
- Returns. Consumers can return goods within 14 days without giving a reason. Allegro’s help page notes a seller can refuse a return when the buyer bought as a company for its business.
Allegro also charges a sales commission that depends on the category. Check the current rates for your categories in your Allegro seller account before you set prices, since they decide whether the same price works on both sites.
A pricing example
Say your PrestaShop shop sells a phone case for 39 zł. On Allegro, a buyer adding it alone stays under the 49,90 zł Smart! line, so they pay for delivery, and you compete with sellers whose cases sit above it. Bundling two cases at 69 zł takes the order over the threshold and gives buyers free delivery. FLUF lets you set a different Allegro price for the same product, so the shop price can stay at 39 zł.
Connecting PrestaShop and Allegro in FLUF Connect
- In your PrestaShop back office, create an access key for FLUF. No module or browser extension is needed.
- In FLUF Connect, open the Channels screen and enter your shop address and that key. FLUF brings in your catalogue, including combinations and their stock.
- Choose Allegro in FLUF and approve the connection on Allegro’s own screen, signed in to your business account.
- Select products, check category parameters and EAN codes, and publish.
What stays in sync
| Situation | What FLUF Connect does |
|---|---|
| Item sells on your PrestaShop shop | Sees the order and ends the Allegro offer and other listings |
| Item sells on another marketplace | Ends the Allegro offer and lowers PrestaShop stock |
| Item sells on Allegro | Not detected. Mark it sold in FLUF, and FLUF ends the item’s other listings and updates PrestaShop. |
| Relisting or offer management on Allegro | Not available |
The Allegro gap is the one to plan around. If you sell the same single item on both, check Allegro orders often and mark them sold straight away. For stock you hold in quantity, the risk is small.
