Any administrator level user with access to Settings & Defaults can modify the default invoicing by navigating to Options > Settings & Defaults > Default invoicing. The default address, fine print, logo, invoice number and taxation can be modified. Intervals supports dual taxation if needed.
To edit an invoice, click on the “Edit default invoicing” button:
If you use QuickBooks or other accounting software the invoice number in Intervals can be changed to line up with your existing invoices. New invoices will be auto-populated with the terms, tax, and second tax (if enabled).
