Hello @Seller_u4GgUdqPWx3Ly,

Michelle at Amazon here. It sounds like you are new, so welcome to Amazon! We are happy you are here. Wholesale listings are products that you buy from an authorized distributor and then resell them on Amazon for a profit.

@Seller_4zBzdtgCyS9EI has provided some great information here in this thread that discusses what is required for invoices as well as other great information you will want to learn before listing.

You will want to go to Seller University before you start to list on Amazon. You may also be interested in joining the New Seller Community Forum group, where new sellers like you are there to support each other.

I hope you find this information helpful and wish you the best in your online sales!

Michelle
