Overview
The bulk update feature lets you update product cost data for many SKUs at once using a copy-paste import flow (no file upload required). This is ideal for:
- Large catalogs
- Quarterly/seasonal cost refreshes
- First-time setup after connecting to Analytics
- Syncing cost data from accounting/ERP sources
Step 1: Open Analytics
Navigate to Analytics from the main menu.

Step 2: Go to Trends Overview

Select Trends Overview from the Analytics navigation.
Step 3: Enter the Product Cost Area
Click Update Product Cost

Step 4: Start bulk import
Click Bulk Update Cost

Step 5: Use the import dialog
- The Import Product Costs dialog opens.

- Select the Store Scope you want to update.
- Set the Effective Date (defaults to today; you can use past/future dates).
- Paste ASIN, AKU and Cost data to Paste Data section
Step 6: Preview and confirm
- Click Preview Import to validate what will be updated.

- Click Confirm Import to apply changes.

- Analytics immediately recalculates profit-related metrics using the new costs.
Best Practices
- Use the Product Cost page’s date-aware view (Time Machine button) to check if a cost already exists for the date you want to update.
- Copy ASIN + SKU pairs directly from the Product Cost page, paste them into the import editor, then add/edit the cost values.
- Test with a small subset first before importing the full catalog.
