An Amazon settlement report is a ledger of everything that happened to a seller’s account over a fixed period, and the deposit at the end of it is a residual, not a revenue figure. Five misreadings account for most of the bookkeeping damage: treating the deposit as sales, ignoring the period boundary, misunderstanding reserves, netting reimbursements into revenue, and reading account level charges as though they were per order fees.
Each one produces a specific wrong number, and each is fixable without new software.
1. The deposit is read as revenue
A $41,300 deposit arrives and gets recorded as $41,300 of sales. The bank reconciles. Every other number in the file is now wrong.
That deposit is gross sales, minus referral fees, minus fulfillment fees, minus storage, minus advertising charged to the account, minus refunds issued, plus reimbursements, plus or minus reserve movement. Gross sales in the same period might have been $58,000. A seller recording the net has no fee expense anywhere in their books, understates revenue by nearly thirty percent, and cannot answer what their fee load is as a percentage of sales, which is the single most useful channel metric they have.
The fees themselves are substantial and category dependent. Amazon’s published seller pricing shows referral fees charged as a percentage of total price or a minimum amount, whichever is greater, ranging up to 45 percent for device accessories with a $0.30 floor, alongside a $39.99 monthly Professional selling plan fee. A gross to net difference of that size is not a rounding item to absorb into one revenue line.
2. The settlement period is treated as a month
Settlement periods run on their own cycle and do not respect calendar month ends. A period beginning on the 26th of September and closing on the 9th of October contains two months of activity, and the deposit lands in October.
Sellers handle this in one of three ways. Some post the whole settlement to the month the money arrived, which shifts revenue between periods and makes month over month comparison unreliable. Some split by settlement date rather than transaction date, which is the same error in a more careful costume. The correct approach is to allocate each line to the month of the underlying transaction, holding the rest in a clearing account until the following period closes it out.
The effect compounds at year end. A December close that dumps a straddling settlement into either December or January moves revenue across a tax year boundary, and that is the version of this error that gets expensive.
3. Reserves are read as lost money
Amazon holds a portion of a seller’s balance as a reserve against returns and chargebacks, and that reserve moves between settlement periods. Amazon documents the components of the report and how the account balance is built in its Seller Central payments reference.
A reserve increase reduces the deposit without reducing sales. Treated as an expense, it creates a phantom cost in one month and a phantom gain in the next when the reserve releases. Treated correctly, it is a receivable: money earned, not yet paid over, sitting as an asset until it settles.
This one shows up most often after a seller’s first inventory ramp or their first suspension scare, when reserve levels move and the books report a loss nobody can explain from the sales side.
4. Reimbursements are netted into revenue
When a marketplace loses or damages a unit, it reimburses the seller, generally at a value derived from selling price rather than from the seller’s cost. Those amounts arrive inside the settlement alongside ordinary sales.
Two problems follow from folding them into revenue. The first is that reimbursement revenue is not sales revenue, and mixing them distorts conversion and average selling price analysis. The second is the inventory side: the unit is gone, so its cost has to come out of inventory and into cost of goods sold, or the balance sheet keeps carrying a unit that no longer exists.
Booked properly, a reimbursement is other income, with a matching cost of goods entry for the unit. Booked as revenue with no inventory adjustment, it inflates both sales and the inventory asset at once, which is the combination most likely to surface awkwardly during diligence.
5. Account level charges are read as order level fees
Settlement reports mix two kinds of charges. Order level items, referral and fulfillment fees, attach to a specific sale and belong in channel cost of sales. Account level items, advertising, storage, the monthly plan fee, long term storage surcharges, coupon redemption fees, attach to the account and belong in operating expenses.
Flattening both into one “Amazon fees” account produces a fee ratio that moves for reasons a seller cannot diagnose. Advertising spend rising ten percent looks identical to a referral rate change looks identical to a storage bill from aging inventory. All three call for different responses, and the aggregated line cannot distinguish them.
The fix is unglamorous: separate accounts for referral, fulfillment, storage, advertising, refunds, and reimbursements, each mapped from the settlement’s own transaction types. It takes an afternoon to set up and it turns the settlement report from an obstacle into the most informative document the business produces monthly.
A worked reconciliation
One settlement period, simplified:
- Product sales: $58,400
- Refunds: $2,310
- Referral fees: $8,760
- Fulfillment fees: $6,140
- Storage: $890
- Advertising: $3,420
- Reimbursements: $310
- Reserve increase: $1,890
- Monthly plan fee: $39.99
Net deposit: $35,260. Every one of those lines exists in the books as its own figure, the reserve sits as a receivable, and the deposit ties to the bank. Revenue for the period is $58,400, not $35,260, and fee load is 27.1 percent of gross sales, which is the number worth tracking month over month.
Doing it at volume
The arithmetic above is straightforward for one settlement and unmanageable by hand at forty settlements a month across five channels. Most sellers past a certain volume move to tooling that maps settlement transaction types into the ledger automatically, which is what ConnectBooks and similar ecommerce accounting products are built to do, each with its own approach to how much detail survives the trip. A2X, for one comparison point, is built around summarized settlement journals, a design that suits practices closing many clients efficiently and gives up some transaction level granularity in exchange.
Whichever route a seller takes, the test is the same. Ask for gross sales, total fees by type, and net deposit for one period, and check that the three reconcile. Books that cannot produce that in under a minute are not reading the settlement report; they are reading the bank.
For the general recordkeeping standard underneath this, the Small Business Administration’s guidance on managing business finances covers what records a business is expected to retain. Marketplace settlements are source documents in that sense, and they deserve the same treatment as a stack of supplier invoices.
