I don't know I can answer this FOR you, however I don't push my software on clients and I've never turned a client away due to software or geographical reason.. its too competitive out there to do that. I've worked on many PM softwares so I have not come across one I either didn't know or couldn't learn on. Today's clients need their billing companies to be diversified and that means we need to be ready to work with whatever setup they have going on. IMHO conversions are messy and rarely full proof. The only time I will try and sell a provider is if they are on an outdated software or things are just such a mess where I can do a "manual'' conversion, and even still if they want to stick with what they have setup, I'll get on board with it most times.
