What Counts as a Valid Ungating Invoice

Short answer

Amazon wants an invoice from the brand itself or one of its authorized distributors, not from a retailer. It needs to match your Seller Central business information exactly, be dated within roughly 180 days, show the minimum unit count Amazon lists for that brand, and ideally show proof it was actually paid. A Costco or Sam's Club receipt fails the first requirement outright: Costco and Sam's Club are retailers, not authorized distributors, no matter how genuine the products are.

I get this question constantly, usually from someone who already has an invoice in hand and just wants to know if it will hold up before they upload it. The honest answer is that "valid" comes down to who the invoice is from, not just whether the purchase was real. A lot of rejected sellers bought something completely legitimate, they just bought it from the wrong kind of source.

What Amazon actually requires in an invoice

The source. It has to come from the brand's manufacturer or an authorized distributor for that specific brand. Being authorized to sell one brand does not automatically make a distributor authorized for another, so check with the brand directly if you are unsure.
Matching information. Your business name, address, and email on the invoice have to match your Seller Central Legal Entity information exactly. One shortened business name or a slightly different suite number is enough to get it rejected.
Recency. Generally no older than 180 days. Amazon lists the exact cutoff on the specific requirements page for the brand you are applying for, so always read it before you upload anything.
Minimum quantity. Amazon specifies a minimum number of units the invoice needs to show, usually at least 10, sometimes more depending on the brand.
Proof of payment. An invoice that just shows a bill, not a completed transaction, is weaker proof than one that shows the amount was actually paid.

All five of these have to line up. Getting four out of five right is still a rejection, which is why paperwork that looks fine to you on a first read still bounces back.

Why a Costco or Sam's Club receipt usually does not work

Costco, Sam's Club, Walmart, and Target are retailers. They sell to the public, including to you and me, but that is a different relationship than being an authorized distributor for a brand. Amazon's stated requirement is specifically about sourcing through the brand's actual distribution chain, and a retail receipt does not prove that, even when the product on it is completely real.

I will be straight with you about something I have seen with my own eyes, because it is more useful than pretending it never happens. I know someone who applied for ungating using an invoice from Target, a plain retailer, not an authorized distributor for anything. It worked roughly 80% of the time, often approved automatically within seconds, no human review at all. Amazon's automated review system is not perfect, and it does not catch every case it should.

⚠

This is not a strategy, it is a gap in Amazon's system. A retailer invoice slipping through does not make it a valid invoice, and it does not give you a real distributor relationship behind that product. If the brand or Amazon ever audits the account later, there is nothing real to point to. Build the business on authorized distributors, not on the odds that a broken review process waves you through.

If you are sourcing correctly, working with the brand directly or with a distributor the brand actually recognizes, this whole question mostly disappears. Finding and verifying a real distributor is the part worth spending your time on, not finding a retailer receipt that might sneak through.

The proof-of-payment detail that actually moves approval odds

Amazon does not just want to see that a transaction happened, it wants to see that it was paid. I have found over the years that an invoice with something like a stamp saying "paid," or a balance showing "$0 owed," gets approved at a noticeably higher rate than a plain, unpaid invoice. Sometimes Amazon will explicitly reject an invoice as a receipt, not proof of payment, which is exactly the distinction this fixes.

Ask your distributor for a copy with a paid stamp if theirs does not already include one. If that is not possible, a matching bank statement showing the same amount leaving your account on roughly the same date works as backup proof. I know someone who did exactly this: downloaded the bank transaction showing the payment, matched it to the invoice total, and used both together.

Watch: what to do when a real invoice still gets rejected

If a valid invoice still gets rejected

This happens constantly, even with a real authorized-distributor invoice, and it does not mean anything is wrong with your sourcing. I do not expect approval on the first try anymore, and I know sellers doing eight figures a year who still get rejected on brands they are perfectly entitled to sell.

Reply to the same case, do not open a new one. Click the case number, not the reply button on the right, then use the blue reply button at the top of that page.
Rename the file every time you resubmit. Keep the word "invoice" in the filename with a different number or suffix each time, since Amazon can treat an identically named reupload as a duplicate.
Alternate the format. If you submitted a PDF, try a photograph of the printed invoice as an image next time. A different format goes through a different review path.
Highlight the specific product on the invoice. This sometimes gets flagged as an altered document, but it often works, and it is worth trying since it makes the reviewer's job easier.
Double-check your Legal Entity information first. Go to Account Settings, Business Information, Legal Entity, and confirm everything matches the invoice before you resubmit anything.

Sales history on the account also plays a real role here, even though it is not part of the invoice itself. I have tested this directly: an invoice got rejected five times in a row, then I focused purely on driving sales for two months, resubmitted the exact same invoice unchanged, and it was approved on the first try. Amazon trusts accounts more as they show real activity, which is worth keeping in mind if you are stuck on a brand and the invoice itself checks every box.

The full resubmission process, including what each specific rejection message actually means, is covered in how to get ungated on Amazon. And if the brand itself is the actual obstacle, not Amazon's paperwork check, that is a different problem covered in how to get brands to approve you as a reseller.

Quick tip

If you do not have an authorized-distributor invoice yet, the fix is upstream of ungating entirely. Going brand direct or working through the right paperwork from the start means you show up to the ungating step with a real invoice already, instead of trying to make a retailer receipt work.

Common questions

Does a Costco or Sam's Club receipt count as a valid ungating invoice? ›

No, not officially. Amazon's requirement is an invoice from the brand itself or one of its authorized distributors, and Costco and Sam's Club are retailers, not authorized distributors. Some sellers have gotten a retailer receipt through anyway because Amazon's review system doesn't catch every case, but that isn't something to build a sourcing strategy around. If it gets flagged later, you have no real distributor relationship behind the account.

Does an invoice from Walmart or Target work? ›

Same answer as Costco and Sam's Club. Walmart and Target are retailers, not manufacturers or authorized distributors, so their receipts don't meet Amazon's stated requirement even though the products themselves are genuine. I've personally seen a Target invoice slip through Amazon's automated review more than once, but that's a gap in Amazon's system, not a reliable path. Treat it as a backup, never as a plan.

How recent does the invoice need to be? ›

Amazon generally wants an invoice no older than 180 days. Check the specific requirements page for the brand you're applying for, since Amazon lists the exact cutoff and minimum unit count right there before you upload anything.

What if my invoice doesn't show proof that it was paid? ›

Amazon treats an unpaid or proforma invoice as weak proof and will often reject it, even from a real authorized distributor. Ask your distributor for a copy with a paid stamp or a zero balance notation, or keep a matching bank statement showing the payment as backup. That single detail changes approval odds more than people expect.

Do I need units already purchased, or can I apply before I've bought anything? ›

Amazon wants to see a real purchase, generally at least the minimum unit count listed on that brand's specific requirements page. You need to have actually bought the inventory from an authorized source before you apply, not just have an agreement in place.

My invoice is from a real authorized distributor and it still got rejected. What now? ›

That's normal, not a sign something is wrong with your invoice. Check that your business name, address, and email match your Seller Central account exactly, since a small mismatch is the most common cause. Then reply to the same case with a renamed file rather than opening a new one.
