Bulk Setting Cost Prices (CSV)

Product Management PIM Cost Price Gross Margin CSV Bulk Setting

You can set product cost prices in bulk using a CSV file. Registering cost prices lets you check gross profit and gross margin in per-product sales analysis, and use that data for profit-focused analysis and AI advice.

Where to open Bulk Set Cost Prices from the menu on the product management screen

Open Bulk Set Cost Prices from product management

Select "Bulk Set Cost Prices" from the menu at the top right of the product management screen. If you only want to update cost prices for multiple products in one go, this screen is more efficient than the bulk product CSV upload.

You can generate a template based on your existing product list, which reduces input mistakes with ProductId or product names.

Where to get the template and upload a CSV for preview on the Bulk Set Cost Prices screen

Enter the new cost prices into the template

Click "Download Template" to get a CSV containing your current product list. Enter the new cost price in the CSV's CostPrice column and save it.

Select the CSV file and run "Upload and Preview" to check the contents before anything is applied. Product data is not updated yet at this point.

Where to check CSV columns, matching method, and warning conditions on the Bulk Set Cost Prices screen

Check the matching rules and warnings

The CSV matches products by ProductId first. If ProductId is blank or doesn't match, it matches by the product name in the Name column. Rows with a blank cost price are excluded from the update.

A cost price below 0 is an error. A cost price higher than the tax-excluded selling price is shown as a warning. Warnings can still be applied after you've reviewed them.

What to check in the preview

The confirmation screen after uploading shows the number of rows to be updated, unchanged, not applicable, warnings, and errors. Check that products are matched to the intended rows and that the CostPrice values are correct.

If there are errors, fix the CSV and upload it again. If there are warnings, check whether it's acceptable for the cost price to exceed the selling price for that product.

Checking after applying

Once you confirm, the products' cost prices are updated and reflected in per-product sales analysis and gross margin calculations. Open a representative product afterward and check that the cost price and profit margin are what you expect.
