Prefixed Invoice Numbers are displayed with the financial year preceding the invoice number. If your firm intends to reuse its invoice numbering each financial year, then Prefixed Invoice Numbering is preferred. This can be set before any invoices are posted under Options, Invoice/Receipt Numbers.
Important: The style of invoice numbering cannot be altered once an invoice exists in Time+Billing.
Example:
Invoice number 552856 was issued on 1/7/2020. As a Prefixed Invoice Number, it would be displayed as invoice number 2020-552856. As a Standard Invoice Number, it would appear as invoice number 552856.
Time+Billing enables you to specify the invoice number to be assigned to each invoice. You are able to manually enter invoice numbers.
Alternatively, Time+Billing can be set up to automatically assign invoice numbers. You can specify manual or automatic invoice numbering as follows:
Log in to Time+Billing.
Go to Options, Invoice/Receipt Numbers.
On the Invoice/Receipt Number Options window, under Invoice, select the required check box.
Click OK to close the window.
