Why it matters

Listing on Amazon was always the bottleneck

Category templates, flat files, upload errors, processing queues. A separate job that had nothing to do with sourcing. Lister removes the entire step.

Frequently Asked Questions

Visit Help Center
Can I list products without a Purchase Order?
Yes. You can select products directly from your Product Database or search by title, ASIN, or UPC.
What fulfillment types does Lister support?
Both FBA and FBM. You set the fulfillment type for the batch when configuring the listing.
Can I track listing errors?
Yes. Failed submissions appear in your Listings tab with the reason for each error so you can fix and resubmit.
What happens to listing status after submission?
Status updates in real time: Pending, Active, Inactive, Draft or Error. Visible in the Listings page.
Can I deactivate listings without Seller Central?
Yes. You can activate and deactivate any listing directly from Seller Assistant.
How are SKUs handled?
On a purchase order, each line without a SKU gets a suggestion. Seller Assistant reuses an existing SKU first. One click links it or creates it. Lister opens from that PO with those SKUs, the PO marketplace, and the condition and fulfillment defaults from Settings > SKUs & listings. You can still assign another SKU or edit the suggestion before submit.
Where do SKU format and listing defaults come from?
Teams set them under Settings > SKUs & listings. The SKU format can be supplier code plus item number, supplier code plus UPC, ASIN plus condition, batch, or random. When Lister opens from a purchase order, the PO marketplace and those defaults are already selected, and each new SKU uses the team format. The prep item uses the same SKU.
