Change invoice numbers
Description

When you first start using Sage Accounting, you'll begin with document Number 1.

If you previously used another accounting system, and you want to start from the last number you used. 

We also add a prefix to help you identify each type of sales document, such as invoices, credit notes, quotes, etc.

NOTE:

You can't reuse an invoice or credit note number ensuring a full audit trail. However, you can reuse quote and estimate numbers.
