If I have a sales guy, will this track his conversions, so that I know what to pay him and when?
EG: Month 1, Mr Smith signes up at $1000/month, and my sales guy gets $200.
Month 2, Mr. Jones and Mr. Green sign up at the same rate, and Mr. Smith renews, so he get's $600
Month 3, Mr. Jones drops, but Mr. Green and Mr. Smith still pay, so he get's $400.

Make it do that and I'll buy instantly.
