PRS Essential Reference > Invoices

When an invoice is created it is assigned to one of any number of configurable invoice types. Many companies just use a single invoice type, others use multiple invoice types to satisfy administrative or legal requirements.

Invoice types can be created, edited or deleted from the Invoice Types dialog (accessed using the Tools->Setup->Invoice Types menu command).

Printed Invoice customisation can be achieved using invoice template files (see the PRS Administration guide for a detailed description of Report Templates).

Invoice Type Parameter	Description
Last Invoice Number	The next invoice number is determined by finding the first unused invoice number greater than this number. The last invoice number is updated when a new invoice is first saved. Initialise this value to one less than the first invoice number you wish to use. Multiple invoice types can share the same number range, just initialise them to have the same Last Invoice Number. Setting the last invoice number to zero will disable the further use of the invoice type (the invoice type will be excluded from invoice type drop-down lists).
Tax number	The alphanumeric tax number to be display on printed invoices.
Edit invoice templates	Pressing the Goto button at the left hand margin of the Invoice Types dialog activates this option. If an Invoice Report Template file for the selected Invoice Type exists then it will be opened in Microsoft Word for editing, if it does not exist you will be asked if you want to create a new Invoice Template file based on default PRS invoice template.
