Some wholesale sellers on Alibaba say that their gin invoices are not accepted on Amazon. However, the sellers who are assured by Alibaba (Verified) say that they can even provide sales authorization certificates and that there will be no problem with the invoice. Based on our experience, I ask if such a situation exists. Would it be okay for me to buy products from wholesalers and manufacturers who provide Alibaba's Verified invoice and sales authorization certificates? ? So, in such a situation, what should I do, how should I behave and what questions should I ask?
