Fund Flow
Funds are normally used in the following order:
Primary Account Top-up → Transfer to Sub Account → Allocate Budget Limit → Create virtual Card → Card Authorization → Transaction Clearing → Review transaction details
Budget allocation does not transfer funds into a new funding account. It places part of the Sub Account Available Balance under Budget control.
After a Budget release, Refund, or transaction reversal, the related limits are restored according to the actual processing result.
