@WayneSchulz This is what Epicor just switched to. You no longer get maintenance payments. The first X$ can be applied toward marketing & selling (i.e. salespeople), and only after a certain threshold, then it can be used against new product purchases and never cash and it expires.
Seriously sucks, but fortunately or unfortunately, we don't have many epicor customers in that situation. The other crappy thing about epicor is if you pick up an orphan and they were sold by epicor direct (85% of the customers in the US), you will never get any maintenance credit or be able to sell them any additional epicor software for a margin. They will give you a commission (lower percentage) if you sell more software.
That being said, their direct implementation group is so crappy, that the amount of actual service revenue falling out of the sky thanks to our strong SEO and video resource sites, is actually quite good and there are far fewer VAR competitors.
