Amazon Seller Central shows you revenue. TrueMargin shows you what you actually keep — after every fee, ad dollar, and return.
Most sellers think they're profitable. Then they run the real math.
Fulfillment fees, storage charges, and referral commissions add up fast. Most sellers don't know their true cost-per-unit until it's too late.
Amazon's ACOS only measures ad revenue. True ACOS measures ad spend against ALL your revenue — and it tells a very different story.
A losing product buried in your catalog can offset all your winners. You won't see it until you break down profit per SKU.
TrueMargin connects to Amazon's official API and calculates what you actually make on every sale.
Revenue minus COGS, FBA fees, referral fees, storage, ad spend, and returns. Finally, the real number.
See your True ACOS across all revenue — not just what Amazon shows. Know exactly when ads are actually working.
Get notified when margins drop below threshold, ACOS spikes, or returns spike on any SKU.
