Does anybody have a comprehensive billing|payment module for sale?

The default Dolibarr one isn’t fit for purpose to me:

  1. I can’t reference the payment orders my clients return to me on the invoice I send back.
  2. There is no way to issue payment reference numbers.

Does anybody have a module I could buy that addresses these things and updates the billing|payments module?

Why can’t you just simply use the invoice id or reference?

Another thing you could do would be to use a Complementary attribute and perhaps even let some code automatically calculate a payment reference for you.

Update on request:

All I need to be done for the time being is a line to be added in the payment terms section which reads: Please reference the invoice number when making your payment.

Hello, you should look at the setup of the invoice module where you can add free text that will be printed before the footer of your pdf.
