An Amazon settlement report is the itemized statement behind each disbursement — the detailed record of every transaction Amazon rolled into the money it sent you. Amazon disburses on a recurring settlement cycle rather than per order, so each report covers a closed period and nets to exactly one deposit. That report, not the bank line, is where the reconciliation starts.
The reason reconciliation takes real work is the number of distinct line types packed into one settlement. A single report typically carries product sales (what buyers paid for your items), referral fees (Amazon's per-sale commission, which varies by category), FBA fulfillment fees (the per-unit charge to pick, pack, and ship, which varies by size and weight), FBA storage fees (the ongoing charge to warehouse inventory), refunds returned to buyers, reimbursements Amazon credits back for lost or damaged units, and a reserve Amazon may hold or release. We name these categories factually and do not quote fee rates, because they differ by product and change over time — what is constant is that each type has to land in its own account. The deposit is simply the arithmetic of all of them: sales, minus every fee and refund, plus or minus the reserve movement, equals the net Amazon wired.
