How It Works

(for eBay Integration)

Step 1

Connect eBay

Connect your eBay account, map locations to our warehouses, and sync orders, inventory, and returns in real time so we can test and validate flows quickly.

Step 2

Configure rules

Define shipping and handling rules once, then let our WMS route orders, apply carrier choices by country, and enforce your tags, priorities, and service levels automatically.

Step 3

Inbound & SKU prep

Send products by truck, pallet, parcel, or container. We receive and check goods, scan and relabel SKUs, and build kits or bundles so stock is shelf-ready for marketplace picking.

Step 4

Storage & visibility

We place each SKU in the right storage location and give you real-time visibility on stock by site, available-to-sell quantities, and movement history for every eBay-listed item.

Step 5

Pick, Pack, Ship & tracking

We pick and pack orders to your SOPs, use your packaging and inserts, follow your carrier rules, ship same-day before cut-off (eligible orders), and push tracking updates back into eBay automatically.

Step 6

Returns & reverse logistics

We handle returns across the EU and the UK by receiving parcels, grading items, restocking what can be resold, and consolidating remaining goods back to you or your suppliers.

eBay is a global online marketplace where private sellers, brands, and retailers list products, manage offers, and reach buyers in multiple countries. With fixed-price listings, promotions, and reputation signals, eBay remains a key channel for merchants who want to diversify beyond a webstore and other marketplaces.

Sellers benefit from the platform's robust Seller Hub, which provides detailed analytics and tools to optimize listings for better search visibility. While originally known for its auction format, the site has evolved to support sophisticated multi-channel strategies through seamless integrations with third-party inventory software. Its emphasis on buyer protection and feedback systems ensures a level of trust that allows sellers to build a loyal customer base across highly diverse product categories.

Can you handle returns across Europe and the UK?

Yes. We can receive returns into our EU/UK network, process them according to your policy, and share results back to you for customer service follow-up.
