Reactivating your Amazon USA account after it's been deactivated due to a "Product inauthenticity complaint" can be challenging without valid invoices. Here are some steps to consider:
1. **Contact Amazon Seller Support**: Reach out to Amazon Seller Support through your Seller Central account. Explain the situation and inquire about the specific reason for the inauthenticity complaint.
2. **Provide Any Documentation**: While you may not have invoices, gather any supporting documentation you do have, such as purchase receipts, communication with your eBay seller, or any other proof of authenticity for the products.
3. **Review Your Product Sources**: Ensure that your sourcing channels are reliable and that you can provide valid invoices for future sales.
4. **Plan for Prevention**: Create a plan to prevent future inauthenticity complaints. This may involve stricter quality control, improved sourcing practices, and enhanced product descriptions.
5. **Appeal Process**: If Amazon provides an option to appeal the deactivation, follow their instructions closely. Be honest and clear in your communication, providing any information that might help your case.
6. **Alternative Supplier**: Consider finding alternative suppliers for the product in question if you can't resolve the issue with your current source.
7. **Comply with Amazon Policies**: Ensure that you're fully compliant with Amazon's policies, including those related to product authenticity, and make sure your listings accurately represent your products.
8. **Monitor Your Account**: Keep a close eye on your account and customer feedback to address any issues promptly.
Reactivating your Amazon account can be a complex process, and success may vary depending on the circumstances. It's essential to maintain open communication with Amazon Seller Support and work diligently to resolve the issue.
