Why was it suspended? What country were you selling in?
You'll have to be more specific about your "invoice" issue. Why was the invoice asked? Was it before or after the suspension?
Were you using FBA or using a third party fulfillment warehouse?
I was selling Headphones through FBA and listed my product on someone else listing, he made IP complaint against me, I had bought those headphones from some other site and gave Amazon Invoice, I was doing Online Arbitrage. This Complaint was made in March, after several discussion with Amazon, Amazon closed my account.
So you were selling branded headphones where you didn't have the rights to do so? This lead to an IP complaint which got you shuttered?
Opening a new account is a hassle, as amazon is very smart when it comes to receivables. Were you using Payoneer for receiving?
Your best bet would be to open a new company with a different registered office address and then utilize Amazon Cross Border Payments. And then the usual, clean IP, different ISP, clean cache etc.
Yes Branded Headphones, I was not using Payoneer, Amazon was depositing directly to my Bank Account
