Amazon profit reporting rebuilds sales into net margin per ASIN after FBA fees, advertising, returns, storage and refunds — so decisions about price, spend and range rest on the number that actually matters.
Every product resolved to a contribution figure after all Amazon costs, which is routinely the first time the loss-making SKUs become visible.
TACoS alongside ACoS, so ad spend is judged against total revenue rather than only against the sales it directly attributed.
FBA fees, dimensional changes, long-term storage, removals and return rates tracked, because these move without announcement and quietly erode margin.
Profit grouped by product line so the range decisions — what to push, what to reprice, what to discontinue — rest on evidence.
Monthly and quarterly trend so a soft month can be read against seasonality rather than triggering a panic response.
A short written monthly summary in plain language, not a dashboard login you have to interpret alone.
Seller Central reports revenue clearly and profit almost not at all. Fees sit in one place, advertising in another, returns and storage somewhere else again, and none of it resolves to a per-product number. The result is that decisions get made on revenue — push the bestseller, cut the slow mover — when the bestseller may be the thinnest-margin item in the catalogue and the slow mover the most profitable.
Rebuilding this properly changes what gets optimised. On one private-label account, monthly revenue grew from $3,488 to $23,668 while net profit went from $1,369 to $8,256 — a 503% increase. Tracking both mattered, because there was a quarter where revenue rose and profit fell 12% as ad spend increased 139%. Without the profit view that quarter would have read as a straightforward win.
Amazon profit reporting is the reconstruction of Seller Central and advertising data into actual net margin: gross sales minus referral and FBA fees, advertising spend, returns and refunds, storage and removal costs, and cost of goods. It resolves to a contribution figure per ASIN rather than a revenue total.
It matters because every meaningful decision depends on it. Target ACoS is only definable against a known margin. Price changes, range rationalisation and inventory bets are all guesses without it. Sellers operating on revenue alone frequently scale a product that loses money on every unit, and the faster it sells the worse the outcome.
Settlement reports, advertising data, FBA fee previews, returns and storage records, plus your cost of goods, are pulled into one model. The rules here change regularly, so the current position is always checked against Amazon’s Seller Central help hub rather than assumed.
Costs are assigned to the products that incurred them, including the shared costs sellers usually leave unallocated because it is inconvenient.
Each ASIN and product line resolves to a net contribution figure, with the assumptions stated so you can challenge them.
A short written summary each month: what moved, why it moved, and what it implies for pricing, spend and range.
The audit rebuilds your revenue into net profit per ASIN, which is usually the first time the loss-making products in a catalogue become visible.
So the audit is tailored to what actually moves your business.
It helps and it is what is normally used, but it is not essential — the same reconstruction can be built from Seller Central settlement and advertising reports. If you already run a profit tool, that gets used rather than duplicated.
Cost of goods per unit, and inbound shipping and duty if you want landed cost rather than ex-works. Everything else comes out of Amazon. Without COGS the reporting stops at contribution before product cost, which is still useful but less decisive.
Seller Central reports each cost category separately and never resolves them per product. The work here is the allocation — assigning fees, ad spend, returns and storage back to the ASINs that caused them so a real per-product margin exists.
It will tell you what each product currently earns and how margin responds to a price change. What price to actually set is a commercial decision that depends on your positioning and volume tolerance, and it stays yours.
Monthly performance reporting is in every plan. Full per-ASIN profit reconstruction is included from Growth at $999 a month.
The free audit rebuilds revenue into net contribution per ASIN. Most sellers are surprised by at least one result.
