How It Works
(for Allegro Integration)
Step 1
Connect Allegro
Connect your Allegro seller environment to our WMS, map warehouses and locations, and sync orders, stock, and returns in real time so we can test and verify flows quickly.
Step 2
Configure rules
Set your shipping and handling rules once—then our WMS routes Allegro orders, selects carriers by destination, and enforces your performance and service levels automatically.
Step 3
Inbound & SKU prep
Send products by truck, pallet, parcel, or container. We receive and inspect goods, scan and relabel SKUs if needed, and prepare stock so it is ready for fast marketplace picking.
Step 4
Storage & visibility
We allocate SKUs to optimal locations and give you real-time visibility on Allegro-ready stock, low-stock alerts, available-to-sell quantities, and full item history.
Step 5
Pick, Pack, Ship & tracking
We pick and pack orders to your SOPs, use approved packaging, follow your shipping setup, ship same-day before the cut-off (eligible orders), and push tracking updates back into Allegro automatically.
Step 6
Returns & reverse logistics
We process returns across Europe and the UK by receiving parcels, inspecting items, restocking what can be sold again, and consolidating remaining goods back to you or your suppliers.
Allegro is one of Europe’s largest marketplaces and a leading e-commerce platform in Central Europe. Sellers list products, manage offers, pricing, promotions, and logistics requirements through Allegro’s seller tools—making it a core channel for brands expanding into Poland and neighboring EU markets. The platform’s "list once, sell everywhere" model allows merchants to seamlessly scale their reach across Czechia, Slovakia, and Hungary using a single unified account.
Furthermore, participation in the Allegro Smart! loyalty program is vital for success, as it provides millions of customers with free shipping and significantly increases repeat purchase rates. By integrating with the One Fulfillment logistics network and offering Allegro Pay for deferred payments, the marketplace removes operational friction and accelerates the transition from local player to regional leader.
