I've been searching net for quite some time now, but I can't seem to find what I'm looking for, which is simple software where I can add my clients and track who has payed his bill, who hasn't and who will soon have to .

I know that microsoft had something like this, but I think they stopped this software.

Is there something like this or do I need to use excel ??

Thank you
