Download the Settlement Detail Report for the target settlement date from Adyen's Report API or the Customer Area; the report is a CSV with one row per transaction in the batch
Parse mandatory columns: Merchant Reference, PSP Reference, Gross Currency, Gross Debit/Credit, Net Debit/Credit, Commission, Markup, Interchange, and Modification Reference
Group rows by your internal order ID (matched via Merchant Reference) and compute net settlement per transaction as gross amount minus interchange minus markup minus commission
Compare each net settlement amount to your internal expected payout computed at transaction time; flag variances above a defined threshold for manual review
Reconcile the batch total net credit against the actual bank deposit amount for that settlement cycle; timing differences of 1–2 business days are normal for non-EUR settlements
Known gotchas
Interchange and scheme fees are estimated at authorization and finalized at settlement; your internal estimate may differ from the final amounts in the report
Refunds and chargebacks in the same batch appear as debit rows with a Modification Reference linking them to the original transaction; failing to link them inflates gross volume
Adyen can split a single merchant account's settlement across multiple bank transfers if accounts are multi-currency; ensure you match each report row to the correct currency ledger account
