Stripe, Adyen, and PayPal merchant clearing reconciliation workbooks — "Undetected merchant fee rate increases draining 40 basis points of gross margin"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
Gateway settlement reports from each processor are downloaded and reconciled to bank deposits and invoices in separate workbooks, netting fees by hand from whatever rate the analyst assumed.
Processor fee schedule changes go unnoticed because fees are derived rather than read, so margin erodes quietly while the workbooks still appear to balance to the deposit.
Gateway telemetry ingestion that pulls settlement, fee, and dispute records from each processor API and a netting pipeline that matches gross receipts, fees, and deposits line by line against the contracted schedule.
Fee assertion: each settlement batch must reconcile gross receipts minus itemized fees to the bank deposit exactly, and any fee line that differs from the contracted rate card is flagged before the batch posts.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
Settlement reports reconciled to deposits with fees netted by assumption.
Fee increases pass unnoticed because the reconciliation derives fees instead of reading them.
Processor APIs supply itemized fees that reconcile to deposits and the rate card.
Every batch nets exactly to its deposit and any fee off the contracted rate card is flagged first.
