We have three options for mapping to product's in Shipstation.
It would be useful to some client's if we could use the product's Part Number value to map to a Product SKU in Shipstation.
Agree, we have several sites and they can't all have a product call Business card but they do. If that is too much work at least have a prefix for each site that is added to the front of the product name and used as the SKU. like ABC-Business card that way all my product/sku on ship station are unique.
