Seller Assistant supports direct integration with prep centers. The Prep centers tab on the Integrations page lists the prep centers you can connect. Once connected, warehouses sync automatically and Purchase Orders can be sent as inbound shipments directly from the Purchase order view.
Connecting Prep Center
Open Integrations and go to the Prep centers tab. Only the team owner sees this tab.
Search by name, country, state or city, or click a country and then a state. Your prep centers come first, then Featured prep centers (when there are any) and All prep centers.
Click a prep center, then click Connect in the details pane. On smaller screens the details open in a window.
Enter the API token. If the token has access to several merchant accounts, pick the one to connect.
On successful validation, warehouses sync automatically and appear in the Warehouses table with a synced badge.
If your prep center isn't listed, click Request a prep center under the list to request it on the Seller Assistant feedback roadmap.
Sending Purchase Orders to Prep
Sending to prep – open a PO assigned to a synced warehouse. A "Send to prep" button appears in the PO header. Clicking it opens a review dialog. It lists each PO line with its matched, suggested or new prep item and the SKU it is sent with. Each line is sent with its own SKU or a suggested SKU. Click Send: Seller Assistant creates the missing prep items and the shipment, and a successful send moves the PO from Draft to Ordered. After sending, the PO header shows shipment status and a direct link to the shipment in the prep center portal.
Changing the warehouse – the warehouse field in the PO header is now an inline dropdown. Click the warehouse name to see all team warehouses with provider logos and addresses. If a shipment is already linked, the dropdown is disabled until the shipment is unlinked.
Unlinking a shipment – available via the PO's action menu. Unlinking removes the connection between the PO and the prep center shipment and deletes the draft shipment in the prep center. After unlinking, "Send to prep" reappears and a new shipment can be created.
Prep Tab and Receiving Gaps
When a PO has a prep shipment, the PO shows a Prep tab. For each line, it shows how many units the prep center received, how many are damaged and how many are missing. The data syncs from the prep center about every 30 minutes.
If units are damaged or missing, you can decide what to do with the gap for each line:
Claim from the supplier, the prep center or the carrier
Accept the loss
Mark the units as still expected
Each save adds one note to the PO with your decisions.
