Short answer: To sell in a gated category or brand, Amazon usually asks for an invoice from a manufacturer or authorised distributor that proves you bought the product as a business. The invoice has to match your seller account exactly. How recent it must be and how many units it must show differ by category and brand, so always read the requirements shown in your own Seller Central application before you buy anything.
Two different approvals
"Ungating" can mean two separate things, and an invoice only solves the first:
- Amazon's approval to sell in a restricted category or a restricted brand. This is where Amazon asks for invoices.
- The brand owner's permission. Some brands only allow authorised resellers. Even with an approved invoice, the brand can still act against listings it has not authorised.
Some brands do not allow third-party sellers at all. Check before you place a large order.
Where to find your exact requirements
Open the product in Seller Central (Catalog → Add a Product → search the ASIN) and select the option to apply to sell. The application tells you what that specific category or brand requires. Amazon's Seller Central Help also has pages on products that require approval and on invoice requirements when you apply to sell; read them inside your account, because they are kept up to date there.
Requirements we see in practice vary widely: the accepted age of the invoice, the minimum number of units, and whether several invoices can be combined all differ from one category or brand to another. Do not rely on a number from a forum post.
What the invoice has to show
The details that matter in almost every case:
- The supplier's full name, address and contact details. It must be a manufacturer or an authorised distributor, not a retailer.
- Your business name and address, exactly as on your seller account. A different spelling, an old address or a personal name instead of the company name is a common reason for rejection.
- Item descriptions that match the products you apply for, ideally with a UPC or model number.
- Quantities and prices that show a real wholesale purchase.
- An invoice date within the window your application asks for.
- A real invoice, not a quote, a pro-forma invoice or an order confirmation.
Submit a clear, complete copy. Do not edit it in any way: altered documents can put the whole seller account at risk, not just the application.
Why requests get rejected
- Retail receipts. Receipts from a store or a retail website are not accepted as proof of supply.
- Name or address mismatch between the invoice and the seller account.
- The invoice is too old for the window in your application.
- Too few units for that category or brand.
- The supplier cannot be verified. Amazon may contact the supplier; make sure its website, phone and address are real and current.
- The brand restricts sellers, whatever the invoice shows.
Letters of authorisation
For brands that restrict resellers, a letter of authorisation (LOA) from the brand owner can support your application. Only the brand owner can issue it, not a distributor. A distributor's invoice proves where you bought the stock; it does not mean the brand has approved you.
A safer way to build a wholesale catalog
- Check restrictions before you buy. Search each ASIN in Seller Central and note whether approval is required.
- Open accounts with authorised distributors that issue proper invoices in your business name.
- Start with ungated products while you build history and supplier relationships.
- Apply for approvals one at a time, with invoices that match exactly.
- Keep every invoice organised by supplier and date. Amazon can ask for them later, for example in an authenticity complaint.
