Revenue Doesn't Matter if Amazon Is Quietly Eating Your Margin
Find the leaks, fix the biggest ones, then watch them every month
Most sellers can tell you last month's revenue instantly and cannot tell you what was left. The gap between those two numbers is made of fees, ad waste, aged inventory, returns and listings that stopped selling without anyone noticing. We find it, rank it by size, and keep watching it.
The leaks are small, constant, and individually forgettable
None of these is dramatic enough to trigger an alarm. That is exactly the problem — they compound quietly for months, and Seller Central is not designed to put them in one place and rank them by what they cost you.
- ✗Advertising spend on search terms that have not converted in months
- ✗FBA fulfillment and referral fees that changed on a product whose price never did
- ✗Long-term storage surcharges on units that have sat since last season
- ✗Stranded and suppressed listings still costing storage while selling nothing
- ✗Buy Box share lost to a reseller, so ad clicks arrive and buy from someone else
- ✗Returns at a rate that quietly moved a profitable SKU under water
- ✗Inbound shipments where fewer units were received than you sent
- ✗Stock-outs on your best SKU that also cost you the rank you had built
The compounding effect is what makes this worth doing. A fee change worth a few hundred dollars a month is easy to ignore once and expensive to ignore twelve times, and the ad waste tends to be the largest single line — it is the one cost that grows automatically while you are not looking.
What We Analyse
The monthly view an owner can actually read
Money in, money out, money left — then the things costing you the most, biggest first. Every line is tagged so you always know which numbers came from Amazon and which ones we worked out.
Money in
- Product sales$184,200Known
- Promotional rebates−$2,140Known
Net revenue$182,060
Money out
- Referral fees$27,630Known
- FBA fulfillment fees$31,410Known
- Storage & aged-inventory surcharge$4,870Known
- Advertising spend$22,300Known
- Refunds & returns$9,120Known
- Landed product cost$61,800Estimate
Total cost$157,130
Money left
$24,930
Estimated contribution profit · 13.7% margin
Marked as an estimate because landed product cost is not in Amazon's data — it comes from you. Give us real COGS and this line becomes known; give us nothing and we will say so rather than invent it.
What needs attention
- 1PPC waste — 41 search terms, no conversions in 60 days$3,180 / monthEstimate
Spend is known from the ad report. The saving assumes those terms are negated and the budget is not simply redeployed.
- 2Aged inventory — 640 units past 271 days$1,240 / month surchargeKnown
The surcharge is charged on the invoice. What the units eventually recover is not knowable in advance.
- 3Suppressed listing — main image fails the size requirementNot estimatedEstimate
The listing is suppressed, which is a fact. What it would have sold is a guess, so we do not put a dollar figure on it.
- 4Reimbursement opportunity — 18 inbound units never received$820 claimableKnown
Unit count and cost basis both come from your shipment records.
Sample data, shown to illustrate the format. These are not a client's results and not a projection of yours. Where cost data is unavailable in a real report, the line says so instead of showing a number.
How Profit Watch Runs
One full audit pass
We go through fees, ads, inventory, listings, returns and reimbursements once, thoroughly, and come back with a ranked list — biggest cost first, with the reasoning shown so you can check the arithmetic yourself.
Work the top of the list
Negatives and bid work on the ad waste, inventory actions on the aged units, listing and Buy Box fixes, reimbursement cases filed. We start where the money is, not where the work is easiest.
Watch it monthly
The leaks come back — fees change, terms drift, a new SKU strands. Monthly you get money in, money out, money left, and what needs attention now, in language you can act on without opening Seller Central.
Audit, Fix, Then Watch
The audit is a real deliverable in its own right. Plenty of sellers take the findings and work the list themselves — the monthly service exists because the leaks come back.

Reported figures depend on the data your Amazon account exposes. Where cost data is unavailable, contribution profit is presented as an estimate with its assumptions stated, and any figure that cannot be estimated honestly is reported as unavailable rather than filled in.
