How do I correct an issued tax invoice?
Returns, discounts and wrong amounts take a credit note; extra charges a debit note.
- 1In Sales docs, open the tax invoice and tap 'Credit note' or 'Debit note'.
- 2Put only the difference in the lines and write the reason in Thai. The original and correct values are worked out for you.
- 3Issue it: it gets a CN / DN number and goes into the month's VAT and the books by itself.
