Adyen rewards scale and punishes the administration for it. The bank shows one batch payout. Behind it sit card payments, wallets and local methods, each with their own fee structure, a few refunds, a chargeback or two and possibly more than one currency. The settlement report holds the detail, the statement holds a total, and connecting the two by hand becomes a recurring spreadsheet exercise that grows with your volume.
Nance closes that gap permanently. It reads every settlement batch from Adyen, ties each transaction to the payout it arrived in, splits fees per payment method, traces refunds and chargebacks back to their source and posts clean entries into your accounting system. Reconciliation becomes something you check, not something you do.
