Change/Reset Invoice Numbers
Invoice numbers are auto-incremental. The CRM increases the invoice ID by one digit, every time a new invoice is created.
You can manually change the next invoice ID via the steps shown below.
The number that you specify is what will be used to create the next invoice ID.
In the event that you want to reset or start over from invoice ID: 0001, you must first delete all invoices in the CRM and then change the number shown in the steps below, to 1.
