Greetings, and this is my first post with you.
When it comes to SKU (Stock keeping Unit), what should I enter if the wholesaler I'm dropshipping from did not specify the SKU, and how could it match one that I placed on my store?
For instance, I have placed in my store a product with a random 9-digit SKU number, and the wholesaler did not. When an order is placed, how can I detect it for such reason?
