I'm Treasurer of our PTA and we use Quickbooks. We have used QB as long as I have been involved (6 years). We also have a pretty tight process in place with a paper trail for every check written and deposit made...so there are rarely errors. When I reconcile QB each month, I run profit-and-loss reports that we present to the PTA at each meeting. QB makes this very simple. We also have a line item in our annual budget for PTA Treasurer administration....which pays for things like Quickbooks, checks, deposit slips, etc.
Is that helpful?
