How are invoices numbered?
Invoices are allocated a 6 character reference number by the system, according to the following format:
Character 1: First initial of customer
Characters 2-6: Consecutive numbering of invoices, system-wide
If you want to match a numbering convention from a prior system or give your invoice a bespoke reference, we suggest you use the invoice title field.
Note: when an invoice is copied from a prior invoice, but the customer has changed for the copied invoice, the new invoice will retain the first character of the reference number from the original invoice.
