We're looking at migrating to PM and this thread has been very helpful.

John, can you tell me how you decided to handle patients with outstanding balances in your old system. My account associate at AC tells me that there is no way to enter a "balance forward" amount in ACPM. This means we'll be running two systems for a number of months until we either collect or write off all balances from our old PM.

If this is the case, I'm not seeing much of an advantage to switching, since I'll be paying licenses for two PM software systems for at least six months.
