I’ve applied more than 20 times for approval to sell the Frontier Co-op brand. Every application has been denied, even though I submit invoices issued directly by Frontier Co-op.
To be clear: Frontier Co-op is the manufacturer of Frontier Co-op branded products, and they also act as their own distributor. My invoices include supplier name, address, phone, website, invoice numbers, dates (within 180 days), my matching business information, UPCs, quantities, totals, and fulfilled transactions with tracking. They also show shipment directly to my business address.
The error message I receive is: “Your application included materials that don't meet our verification standards for demonstrating valid supply chain relationships. You can provide updated documentation that fulfills the criteria listed in this message.”
That typo in the beginning of the error message makes me feel like no human is reviewing these cases, just an automated system kicking them back. I am also providing proof of a valid supply chain relationship by submitting invoices from the manufacturer/distributor of the brand itself in which I hold a wholesale account with.
I need this escalated for manual review. Not too sure what to do at this point other than just keep trying. Has anyone gotten past this loop with Frontier Co-op or other brands where the manufacturer is also the distributor?
Edit: I had Amazon Support review the invoice, and they said it meets the requirements (if thats worth anything).
From my experience, this kind of endless rejection loop happens often when Amazon’s ungating system misinterprets manufacturer-issued invoices, especially from brands like Frontier Co-op that act as both supplier and distributor.
The automated system often flags them because it expects to see a “third-party distributor” name rather than the brand itself. Even though your invoices meet every requirement, the verification process is mostly handled by automation unless it’s specifically escalated.
The best thing you can do now is open a case under “Products and Inventory → Brand or Category Approval → Other Issue,” reference your previous application IDs, and ask for “manual verification by the Category Compliance team.”
You should attach your Frontier Co-op wholesale account confirmation email, business registration, and a screenshot from the Frontier Co-op website showing that they sell wholesale directly to retailers, that combination often forces a manual review.
You can also try submitting the invoice again but adding a brief cover note explaining that Frontier Co-op is both the manufacturer and authorized distributor, with your wholesale account number clearly listed.
Some sellers have reported success by faxing invoices via the “Upload Documents” link and requesting escalation through Account Health Support, which sometimes triggers human review. It’s tedious, but persistence and clarity about the manufacturer-distributor relationship usually get it approved after multiple rounds.
