Keep customers informed when the payment result is uncertain.

Confirm the actual provider account

Your business approves the seller, offer, customers, prices and refunds. Confirm eligibility, supported methods, authentication, settlement and authorised test access with the intended provider or platform.

Review the visible details

Agree KRW display, rounding, fees, invoice information and cancellation wording where relevant. Have the appointed language reviewer check instructions, confirmations and errors.

Test delays and retries

Include abandoned authentication, duplicate notifications, timeouts, delayed results and refunded outcomes. Avoid duplicate fulfilment and give staff a clear route to investigate uncertainty.

Reconcile the records

Connect order and provider references, settlement, refunds and accounting. Your qualified advisers determine applicable tax and invoicing requirements.
