HOW IT WORKS

Status, cost, and history — in one SKU table

One table. Updated as you list, order, and ship.

Why it matters

Incomplete SKU data is an invisible cost

Landed cost gaps, missing SKU history, and inactive listings all affect what you actually make per unit. None of them surface unless you look.

Cost accuracy

Actual cost from your own data

Landed cost comes from the purchase orders behind each SKU.

SKU history

Full SKU history, one tab away

One product can accumulate multiple SKUs over time. Open any product record and the SKUs tab shows every seller SKU attached to it — status, landed cost, and creation date.

Frequently Asked Questions

Visit Help Center
What is the SKUs database?
The SKUs database is a central table of all your seller SKUs — synced automatically from Amazon and created through Lister. It shows listing status, channel, and landed cost for every SKU in one place.
How are SKUs synced from Amazon?
SKUs sync automatically from your connected Amazon account. Any SKU created through Seller Assistant's Lister also appears immediately. No manual import required.
How is landed cost calculated?
Landed cost is pulled from the purchase order the SKU was created from, including unit cost and order-level expenses. If a SKU appeared in multiple purchase orders, cost is calculated as a weighted average. FBA inbound fees from linked shipments are added automatically. You can filter the table by cost source to see SKUs whose cost comes from a purchase order, a weighted average, or a manual override.
Can I override landed cost manually?
Yes. You can manually adjust any component of the landed cost — unit cost, PO expenses, prep fees, or inbound costs — directly from the cost breakdown panel.
How do I see all SKUs for a product?
Open any product record and click the SKUs tab. It shows every seller SKU attached to that product — including status, landed cost, and creation date.
What listing statuses are shown?
The SKUs table shows Active, Inactive, Pending, Draft, and Error statuses. For error-status SKUs, hovering over the row shows the failure reason so you can diagnose and fix it.
How does Seller Assistant suggest a SKU on a purchase order?
A line without a SKU gets one suggestion. Seller Assistant looks for an existing SKU of that product in the PO marketplace and offers it first, including an unlisted draft. If none exists, or the team creates a new SKU for each order, the suggestion uses the format in Settings > SKUs & listings: supplier code plus item number, supplier code plus UPC, ASIN plus condition, batch, or random. One click links the existing SKU or creates the new one. Send to prep uses that same SKU on the prep item, so the prep center and the Amazon listing stay aligned. Reusing that SKU keeps its cost history.

Your SKU data is already there
