I can't seem to find a way to create unique invoice numbers. It is just numeric which means with multiple sites will end up using the same numbers plus I want to be able to look at the invoice number and know where it came from. So a way to add some text characters in front of the invoice number would work.
From what I can tell the invoice number field is just a sequential numeric value and so I was thinking that editing the invoice template to add some unique characters on the invoice number line would work but can't figure out how to do that. Any ideas or knowledge of ways to do this that I have missed?
