I created a selling account this week. I’ve filled out some selling request applications and keep getting denied despite working directly with the Manufacturer

Amazon’s application process just requests an invoice to prove my products are official. I buy directly from the manufacturer on these items I’m applying for. I’m part of the manufacturer’s wholesale team. In some cases I even have my own agent that I work with in case of any issues. I’ve mentioned this in the comments section of my application. Amazon isn’t giving me actual reasons for denial. All they say is “We evaluated the information you provided, but it did not pass our inspection”. Crazy that an actual wholesale invoice directly from the company isn’t a qualifying invoice for them. Am I supposed to speak with my wholesale agent and request a custom invoice typed up specifically for Amazon? Like I said, only some of my brands I work with have me speaking with an agent. Others I’m less involved with and just get discounted pricing so I seriously doubt they’d type up a custom document for me.
