The app ships via FBA the Shopify SKUs that have a matching SKU on Amazon FBA. When the SKUs on Shopify and Amazon do not match the app does not ship via FBA automatically.
If you have different SKUs on Shopify and Amazon then you can use the SKU mapping service to link the different SKUs so that the app can ship via FBA even if the SKUs don't match.
Consider, you have an item with SKU 1056752CS on Shopify. The same item has the SKU test-US on Amazon FBA US.
To bulk map the SKUs follow the steps below:
1) Go to settings >> SKU Map >> Bulk SKU Map using CSV >> upload the CSV file.
2) Click "next" and map the columns correctly.
3) Verify the data and click "submit"
4) check the Mapped SKUs
Thats it !!
