Your own warehouse, a third-party one, a marketplace holding stock on your behalf and whatever handles what comes back each keep part of your inventory and each report it in their own way. These are the fulfillment systems that connect.
A fulfillment connection carries an instruction one way and facts the other. Out goes what has to ship, to whom and from where. Back comes what actually shipped, the tracking the buyer will ask about, what is still on the shelf at that location, and what has come back through returns. The return leg is the one that keeps the sellable number honest, which is why a connection that only pushes orders out leaves the harder half to a person with a spreadsheet.
This page is the fulfillment lane, covering warehouses and warehouse systems, third-party logistics providers, marketplace programmes that hold stock on your behalf, returns platforms and the workflow tools that sit between them. The full integration directory covers sales channels, shipping and ERP or accounting as well. If you are still deciding who should hold the stock, start with 3PL versus in-house fulfillment; if the question is how much of the handoff should run without anyone touching it, see fulfillment automation.

View integrationTwo directions. Out goes the instruction: which order, which items, which location ships it and how. Back comes confirmation of what shipped, the tracking number, the stock still held at that location and anything returned. The inbound half is the part people underestimate, because it is what stops the number your channels are selling against from drifting away from what is on the shelf.
Stock has to be held per location rather than as one pooled figure, and every order needs a location attached to it before anyone picks. Without those two things a second warehouse or a store that ships is just a second set of numbers to reconcile by hand. The connections in this lane are what make each location report its own position.
Try the search box first, since a provider is often listed under the name it trades under rather than the one on your invoices. If it is genuinely not here, select any card marked Request, or use the band below, and the request reaches the team with the provider name attached.
Yes. A return is a fulfillment event in reverse, and until the unit is inspected and put back it is neither sold nor sellable. Returns platforms sit in this lane because the thing they have to tell you is the same thing a warehouse has to tell you: what is on the shelf now.
On the full directory at /integrations, which lists every lane. This page is the fulfillment lane only, so the count in the results bar is the number of fulfillment integrations rather than the number of integrations overall.
