Advance balance
A top-up is an advance for future services, not a separate delivered service. Usage is recorded when a document is created or a plan is purchased. Live payment methods require payment service connection
Billing errors
Report duplicate or incorrect charges with date, amount and operation ID. Do not send card details, passwords or private signature keys
Unused advances
Refund requests are assessed against the unused balance, delivered services and mandatory law. Refunds go to the original payer.
Closing documents
Completion certificates are prepared for delivered services, not counted again for each top-up. Electronic invoice registration is shown only after confirmation by the government system
