BidBeacon Bid on profit, not ACoS.
Are your Amazon ads making money?
BidBeacon works out how much you really keep from each product sale and compares it with what you spend on ads in every campaign and marketplace. You see where advertising pays off and where it burns your margin – and you get a ready file with bid changes.
For Vendors (Vendor Central) and FBA Sellers. European marketplaces: DE, FR, IT, ES, NL, BE, PL, SE, UK.

Example result for four marketplaces
The light band is the range in which advertising pays off. It ends at the break-even point calculated from your product margins. The marker is the actual ACOS of the marketplace.
In ES, every euro spent on ads above the threshold is a loss: break-even is only 9%, because products in this marketplace have a low margin after FBA fees.
From Amazon reports to a file of changes
No account access or integration needed. You upload reports you can already download from Amazon, and you apply the changes yourself through Bulk operations.
Upload your reports
Three Amazon Ads reports per marketplace, sales for the same period and your product costs.
We calculate margin and break-even
For every product and marketplace: what is left after all costs. That is the highest ACOS at which advertising still does not lose money.
You approve the changes
A list of recommendations: lower a bid, raise it, pause, add a negative keyword. Each one shows the reason, and you decide.
Upload the file to Amazon
You get a Bulk operations file with the approved changes and a check sheet to review.
Two ways of selling, one way of calculating
Break-even ACOS depends on what you keep from a sale, and that is calculated differently for Vendors and Sellers. Everything after that is the same for both.
Vendor
You sell wholesale to Amazon through Vendor Central.
- Sales
- Retail and Business reports from Vendor Central, Manufacturing view.
- Prices
- Your Amazon price list and the cost of each product.
- Fees
- DMG, MDF and freight deductions as a percentage of price, promotions and vendor funding.
The margin is calculated from the retail price, because that is what Amazon uses for ACOS. Using the wholesale margin as the threshold usually doubles it.
Seller FBA
You sell yourself through Seller Central with Fulfilment by Amazon.
- Sales
- The orders report – the price and VAT charged on every order, including sales to other EU countries.
- Fees
- The transaction report: actual referral fee, FBA fee, storage and returns. Without it, FBA fees from Amazon's July 2026 rate card, based on product dimensions.
- Costs
- Purchase or production cost and shipping to Amazon's warehouse.
Profit per unit = gross price − VAT − referral fee − FBA fee − storage − product cost.
What you get from every analysis
Results on screen and in Excel files you can pass on.
- Ad profit in eurosHow much you made or lost on ads after all costs, by marketplace and by product.
- Break-even ACOS per productA separate one for every ASIN and marketplace, not a single rule of thumb for the whole account.
- TACoSAd spend as a share of total sales – when the report periods match. If they do not, the field stays empty instead of being wrong.
- Loss-making productsProducts that lose money even before advertising. Every campaign on them adds to the loss.
- Terms to excludeSearch terms that cost money and sell nothing.
- Where to add budgetProfitable keywords with low top-of-search visibility.
