The products you import will have AliExpress/Tmall SKUs. However, if the AliExpress/Tmall SKU is too long, it may not be suitable for every business model. You can turn on a button in DSers to optimize the product SKUs.
Turn on in the "Use the supplier ID as product SKU" section.
After you turn on the button, the product SKU will be replaced with "supplier product ID-variants name" the next time you import a product to DSers Import List.
