How to Issue
The types of cash receipt can be distinguished between the “cash receipt for transaction approval” type, that is issued for either income deduction usage or proof of purchase usage and “cash receipt for revocation” to cancel the partial or total amount of a transaction.
On principle, a cash receipt needs to be issued on the same-day as the occurrence date of a transaction. But for exceptional cases including a delayed payment, it can be issued within 5 days from the occurrence date including the very date of trade.

2. Cash Receipt for Revocation
This type indicates when a cash receipt is issued for a partial or total amount of a transaction. The total amount of the cancelled cash receipt cannot exceed the amount of the original approved cash receipt.
Process of Cancelled Issuance
If a seller wants to cancel the total amount of a cash receipt that is already issued, it can be proceeded by using ‘date of trade’ and ‘NTS confirmation number’ of the original approved cash receipt. For a partial amount cancellation, add ‘amount for cancellation’ in addition to the values mentioned above.
