To route your orders from your non-Amazon sales channel to FBA, you will need to ensure that one of those two steps has been taken:
- You use the same SKUs across all sales channels.
- This means if your SKU in FBA is 123, then in your non-Amazon sales channel, the product will also have to have SKU 123
- If your Amazon FBA SKU does not match your non-Amazon SKU, then you will need to assign the FBA SKU as the a supplier sku to those items.
- See this support article on where do I edit my Supplier SKU for dropshipped products for instructions
If the SKU numbers in your non-Amazon sales channel don’t match what FBA has stored or the FBA sku has not been set as the supplier sku, then a dropship request to FBA will fail and FBA will return an error message.
