I think that's kinda "how they getcha"....nobody really wants to switch software if they like it, so they pull you in with lower prices, then steadily increase the cost, people are more likely to just raise their client prices 5-10% (which we should be doing anyhow!) to keep up with their software price increase rather then switch software.

A several hundred dollar price increase each year is only adding 1 more client to your practice and that should cover it, doesnt seem too unreasonable.

Demo some of the ones out there, see if you can find something you like better, now's the time to do it!
