When importing orders in the Order Fulfillment App, why do I get an error message for the product saying “Invalid SKU”?

When importing an order into Pending Order within the Order Fulfillment App, if you get a message that says Invalid SKU, this means the SKU used for the product in your store (Etsy, Shopify, Squarespace, etc) has an SKU that is not tied directly to FinerWorks (your virtual inventory or a valid FinerWorks product code). You will need to correct this on the  store’s platform for future orders to avoid this error.
