How to backdate a document

Legally, you cannot issue documents of the same type and sets with dates earlier than the last document issued (even if it has been cancelled).

If you wish to generate a document of the same type (Invoice, Receipt, Credit Note) with a date prior to the last document issued, the solution is to create a new document sets or use a sets that has not been used recently.

Follow these steps:

1. In this example, the last invoice in document set A was issued on 17/02/2026.

If you attempt to issue a new invoice in that sets with an earlier date, a warning will appear indicating that the date must be equal to or later than the date of last invoice, which in this case is 17/02/2026.

2. The solution is to create a new sets and issue the documents with the desired date, or use a sets that has not been used recently. To learn how to create a sets, please consult this guide.
