Amazon suspended my seller account - $47K in funds held, won't tell me why

EDIT: added more context below. Woke up this morning to an email saying my Amazon seller account has been suspended for "violation of Amazon policies." No specifics. No warning. Just suspended.

I've been selling on Amazon for 3 years. Mostly private label home goods. Account health was at 99.8%. Zero IP complaints. Less than 1% order defect rate.

They're holding $47,000 in my account - orders that already shipped and were delivered. I can't access Seller Central. Can't contact my buyers. Can't respond to messages.

The email says I can "appeal" but gives zero information about what I supposedly violated. How am I supposed to appeal when I don't even know what the problem is?

Is this normal? Do I need a lawyer? This is literally my entire business income.

Real talk: just wanted to add my experience since I went through something very similar last fall. My account was suspended for related account violations, which turned out to be because my bookkeeper had logged into Seller Central from her home office where her husband also runs an Amazon account. Amazon flagged the shared IP address and suspended both accounts.

I spent three weeks trying to figure out the reason before discovering the IP overlap. My Plan of Action had to include a detailed explanation, proof that the two businesses were unrelated, and a commitment to use a dedicated connection for Seller Central access going forward fwiw.

The lesson: Amazon related account detection is extremely aggressive. If anyone in your household, office, or even the same WiFi network has another seller account, you can get flagged. Under Section 3 of the Business Solutions Agreement, Amazon reserves the right to withhold funds from any account they suspect is related to a suspended account.

For anyone dealing with this specific issue, the INFORM Consumers Act of 2023 requires Amazon to provide certain information about why they are taking action against high-volume sellers. If you have over $5,000 in annual sales, you may be able to invoke this to get more specific information about your suspension reason.
