Fulfillment for Allegro sellers
Selling on Allegro, and packing is eating the time you should spend on your listings and your customers? We take over warehousing, picking, packing, shipping and returns for your Allegro orders. Orders from your own store and other channels ship from the same warehouse in Łódź.

How does Allegro fulfillment work?
An order placed on Allegro flows straight into our WMS. The warehouse picks the products, packs them by robot or by hand, prints the shipping label and hands the parcel to the courier. Order statuses and stock levels flow back to your sales panel, so your Allegro listings only show what is actually on the shelf.
You handle sales, pricing and talking to buyers. We make sure the parcel ships on time, arrives well protected and reaches the right address.
From an Allegro order to a parcel at the door
Account integration
We connect your Allegro account to our warehouse through the Base integration or our API. Our IT team helps with setup and testing before go-live.
Goods receipt
You book in a delivery and we receive the goods into stock in the WMS. From then on you see stock levels in real time.
Picking and packing
We take shipping orders until 8 PM. The robot cuts each box to the size of the product, and kits and fragile items are packed by hand.
Shipping and returns
The parcel goes to the courier with a tracking number. We receive returns from buyers, check them and put the product back into stock when it can be sold again.
What you gain as an Allegro seller
Orders until 8 PM
Evening orders ship on the agreed schedule, with no after-hours packing on your side.
One warehouse for every channel
Allegro, your own store and other platforms draw on one stock pool, so you never split inventory between locations.
A box that fits the product
The robot cuts each box to the size of the order, and our packers handle anything that needs protecting by hand.
Returns handled by us
We receive returns, check the product's condition and put it back on sale. Your system is updated automatically.
Integration through Base and API
Completio is listed in the Base integration catalog, so you can connect your Allegro account to our warehouse without building a connection of your own. If you also sell in your own store, we have ready-made integrations with Shopify, WooCommerce and PrestaShop, plus an open REST API with a sandbox.
Our own IT team maintains the integrations, with no third-party contractor in between. Technical details are on the WMS integration page.
