I disagree with the poor reviews for lack of support on nBill Lite...as with Joomla, the very best way to get support for nBill Lite is via the forums, which a) likely have answers already and b) are quickly reviewed and responded to by the author of the program. I had an issue with the PayPal gateway that after poking around myself and not finding answers, I had to post my own quesiton, and it was answered clearly and with useful information within an hour. The product itself is a wonderful addition to my business, which includes a very thorough billing system including customer interaction (view invoices, graceful payment options, etc.), reporting, proactive monitoring, callback payment notifications, income projections, and much much more. I would like to add, that nBill is the *only* component of this commercial caliber which has a non-commercial option (Lite).
