Keep the customer message and payment records in agreement.

Confirm the offer and actual account

Your business approves the seller, service, customers, price, invoices and refunds. Confirm eligibility, supported methods, settlement and authorised testing with the intended provider.

Make currencies and status clear

Agree where PLN appears and check formatting and rounding. Distinguish display, charge, settlement and accounting currencies. Explain pending, confirmed, failed and refunded outcomes accurately.

Handle delayed and repeated actions

A second click or repeated notification should not create extra fulfilment. Keep references and an investigation route for staff when records disagree.

Reconcile the transaction

Connect order, provider, invoice, refund and finance records. Your qualified advisers determine applicable tax and invoicing requirements.

Review the NBP and tax starting points, data handling or discuss an approved integration.
