Hi Russell,
Yer I understand about the till paid bit and agree with you. The problem obviously as a result is that no customer would know how to pay until they got the invoice, so its a vicious circle

I also understand about dev time on 2.0 having priority. I personally cannot wait for 2.0 as it bring so many things with it that I already need lol, and then most of all, the 1.5 support without the need for legacy (so native id assume?).
Well if we have any talented php coders out there who dont mind doing the nbill community a favour.

A simple Offline Payment gateway would be awesome

Regards,
Tom.
