Keep the payment and service records connected.

Confirm the commercial arrangement

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

Distinguish the currency roles

Agree where VND is displayed and check formatting and rounding. Keep display, charge, settlement, refund and accounting currencies explicit.

Handle uncertainty without duplicate work

Test pending, failed, delayed, refunded and partially fulfilled outcomes. A retry or repeated notification should not create extra fulfilment. Give staff the references and information needed to investigate a mismatch.

Join the records

Connect orders, provider references, receipts, refunds and finance records. Qualified advisers determine applicable tax, invoicing and other professional requirements.

Review the official banking and tax starting points, data handling or discuss an approved transaction.
