Is anyone trying to work with Practice Perfect data for Physiotherapists?

Hi, 

I have a physiotherapy clinic as a client and they use Practice Perfect as their POS / Medical Billing/ appointment and client tracking.  This is the second year end that I have completed with them and we are not able to balance our deposits and sales at the end of the year.  They told us to use the reports monthly based on date of applied payment but come the end of the year there are differences.  They say that the system is a fluid system and there is no way to look up adjustments or run a report based on adjustments by months.  

My main question is...If anyone else is using this system and integrating it with Sage 50 Canadian, do you have any tips for me and can we talk via phone so I can pick your brain in person.

Thanks in advance,

Krystal
