Would you always fight to prove your innocence with invoices, etc., or just click “acknowledge” and not be able to sell that ASIN again?
Don’t ever acknowledge the case because it will complicate the case and you won’t be able to proof yourself. Do you have the necessary documents for the product inauthenticity case
Always fight never acknowledge in my opinion. If you are going to acknowledge it means you are wrong.
The best approach depends on the specifics of the situation, but in general, it’s wise to fight authenticity complaints if you have valid invoices from a legitimate supplier that meet Amazon’s requirements—especially if the ASIN is profitable or part of your long-term catalog. Providing clear documentation (invoices with matching business details, proof of payment, supplier contact info, and sometimes product photos) can help clear the complaint and protect your account’s long-term health. Simply clicking “acknowledge” and letting the ASIN go might be a safer short-term move if you’re unsure about your documentation or the product’s sourcing, but it won’t clear the complaint and may hurt your account health if you accumulate more of them. The key is to prevent repeat complaints by reviewing your sourcing practices and being extra careful with gated or brand-sensitive products.
