Payments · Serbia
Keep the order and payment clear when something goes wrong.
A checkout needs more than a working button. Customers need an understandable result, and staff need a record they can match with the payment provider.
Confirm the business and provider
Agree the seller, customer locations, currency display, price, invoice details and refunds. Confirm that the chosen provider supports the actual business, account and transaction before building around it.
Handle pending and repeated actions
Keep pending, confirmed, failed and refunded outcomes distinct. A second click or delayed provider message should not create a second order or fulfilment. Show the customer how to get help.
Make records easy to reconcile
Match the order, provider reference, customer receipt and staff view. Give a named person a way to follow up on an unmatched payment, dispute or refund.
Agree the professional requirements
Your organisation and qualified advisers decide tax, provider eligibility and any regulated financial requirements. The technical work implements the approved arrangement.
Use the NBS instant-payment starting point and payment-institution pages with your responsible reviewers. See data planning or discuss the transaction.
