If you sell on Amazon, you will eventually hit a gate: a category or brand that needs approval before you can list. Approval nearly always comes down to one thing, the quality of your supplier invoices. Having helped a lot of trade customers through ungating, here is what actually matters.
What Amazon looks for on an invoice
Reviewers check invoices against a short list: your name and address matching your Seller Central account exactly, the supplier's name, address, phone number and website, an invoice date within the last 180 days, at least 10 units of the product you are applying for, and no obvious edits. Pro-forma invoices and order confirmations are routinely rejected; it needs to be a real VAT invoice for a completed purchase.
Why the supplier you buy from decides the outcome
Amazon can and does verify suppliers. An invoice from a distributor with a verifiable trading address, a registered company number, a working phone line and a real web presence passes checks that a marketplace receipt or a cash-and-carry till slip cannot. Invoices from authorised distributors, meaning distributors whose stock comes from the brand owner with paperwork to prove it, carry the most weight, because they answer the question Amazon is actually asking: is this stock genuine?
Practical steps that improve your odds
Match your details before you buy. The name and address on your trade account should be identical to your Seller Central legal entity. Fix this before ordering, not after rejection.
Buy the units in one order. Ten or more units of the specific product, on one invoice, is cleaner than quantities spread across orders.
Ask your supplier for ungating-ready invoices. A distributor who supplies marketplace sellers regularly will know exactly what the document needs to show. Ours do, and if an application is rejected we will look at the rejection reason with you and reissue documentation where something on our side can be improved.
Keep the chain of custody. Keep invoices filed by brand. Future applications, and any authenticity complaint Amazon raises later, are answered with the same paperwork.
Gated categories exist because Amazon is trying to keep counterfeit stock out. Source from a supplier who can prove where stock came from and the gates mostly open on the first attempt.
