How are invoices numbered?
This article explains the invoice numbering system that's used when you create invoices in ExpensePlus.
When you create an invoice, the system allocates a 6-character reference number to the invoice. For example:
S00007
where
character 1 is the first letter of the customer name
characters 2-6 are consecutive invoice numbers, system-wide.
This might result in the following sequence of invoice numbers:
S00001, B00002, B00003, J00004, etc.
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: Where an invoice has been created using 'Copy existing invoice', but the existing and newly created invoices are for different customers, the new invoice will retain the first character of the reference number from the original invoice.
