Hello, I am an individual seller from Malta, and I intend to sell prints on Amazon, my US seller portal is ok as I can sell on it but in the EU like UK or Italy I need to submit my LOA before I can start selling, and after I contacted Amazon seller they told me that the letter of authorization is not the document they are after, they want me to submit a business document like a VAT certificate for a sole proprietor, or a Certificate of Incorporation for a limited business. I filled the LOA using a template they provided but it seems useless. What do I need to do? I don't have a VAT certificate, as I have never even sold anything on Amazon yet. Thanks!
