Landed Cost provide a per-listing cost breakdown for each SKU, combining all major cost components into a single view. You can find Landed Cost in the SKUs table in Inventory section.
Manage Landed Cost
Click on the Landed Cost in the product row. The Cost Breakdown panel shows per-listing (one pack you sell on Amazon) costs, including:
Unit cost (per listing)
PO expenses (per listing)
Prep Cost
FBA Inbound Cost
FBM postage
Merchant-fulfilled orders only. Not part of landed cost; it is deducted as its own P&L line. Enter your average postage per unit: the carrier cost you pay. The shipping charge the buyer pays is a separate amount read from Amazon. It is added to the buyer total for profit and for price comparison, and it is not subtracted from postage. While this is unknown, profit for this SKU cannot be calculated.
The cost components are calculated for one sellable unit, which is one pack that you sell on Amazon. For example, if a Purchase order item has the Amazon Pack Qty of 6, the Unit Cost is the cost of one unit multiplied by 6. If the item has the Case price type, the cost of one unit is the case price divided by the Case Quantity. Purchase Order Expenses (shipping, tax and miscellaneous) are divided by the number of units on the order, then multiplied by the Package Quantity of the listing. This is the same share that purchase order profit uses.
Each component is labeled by its source:
SKU is linked to a product in a Purchase order
Weighted average cost, if SKU was linked to a product in a Purchase order
Manually entered values
From Cost Settings for Price List Analyzer
You can modify any cost component. To restore the calculated value, reset the field.

To bring in costs for many SKUs at once, use the SKU import page. Open it from SKUs (Import from file) or from any Import costs button. It replaces the old Import from Sellerboard button.
Choose file: upload a Sellerboard export, a Seller Assistant template, or any CSV or XLSX file, up to 20 MB, with no row limit. Old .xls files are not accepted. In an XLSX file, Seller Assistant picks the first sheet that has a SKU column in its header. You can switch to another sheet before the rows are saved. This helps with Apple Numbers files, which can put a summary sheet first.
Review: every row is shown under All, Will change, Errors, and Skipped. Two choices set how the rows are saved: When a SKU has a value (Replace it or Keep it), and Blank cells (Keep the value or Clear the value).
Apply: saves the rows that change. Undo asks first and puts the old values back. History keeps your past imports, with Undo on each one.
What the file can set:
Unit cost, FBM postage, minimum price, and maximum price. The file does not set MAP and cannot mark a cost as unknown.
Blank cells: choose Keep the value to leave the current cost when a cell is blank, or Clear the value to remove it. A cost of 0 and a postage of 0 are saved as real values. A minimum or maximum of 0 clears that limit.
Rows match on SKU and marketplace. A Sellerboard row has no marketplace, so its cost is written to every SKU with that code, in each marketplace (deleted SKUs are skipped). Postage, minimum, and maximum need a marketplace in the file.
When a SKU has a value: choose Replace it to write the value from the file, or Keep it to fill only empty values.
Any change to a cost or postage recalculates the costs on your existing orders. This includes applying or undoing an import, Edit prices and costs in Repricer, the cost editor, the API and MCP.
Automatic Updates and Cost Behavior:
Costs update when a Purchase Order is completed or its expenses change. For a SKU linked to a Purchase order item, they also update when the cost, Amazon Pack Qty, Price Type or Case Quantity of the item changes
Unit cost is taken from the latest linked PO or calculated as a weighted average. The weighted average is the total cost of the completed Purchase Orders divided by the number of sellable units in them
If no PO data exists, values remain empty until entered manually
FBA inbound costs locked for closed shipments and updated on each sync for open shipments
