Resetting Invoice Numbers

If you need to start invoicing at a specific invoice number, void the preceding invoice number.

For instance, you might be using only one (numeric) invoice sequence for every customer, and the last invoice printed was 1234. Now you want to restart your invoice sequence starting with 2000. In the Voided Invoices, Debit and Credit Memos form, enter invoice number 1999 as voided. This updates the Last Invoice Number on the Invoice, Debit and Credit Memo Sequences form. Then, when you generate your next invoice, it will be numbered 2000.
