Simple Invoices - Forum

I had a similar requirement ie. to use custom invoice numbers and not the auto generated ids. As per suggestion from a different post, I use custom_field1 from the invoice table (via settings) and in the UI enter a invoice number as per my choice. Also modified the template to use that number instead of the ID. Max of 10 minutes is all it takes and it should be done!

Validating would imply writing some code, you could maybe think of writing an extension and integrating it into your code.
