?Hi, Mr. Jan.
I've never used QuickBooks, but in my opinion, Quicken is not suitable for any third-party accounting situation.
By "third-party" situation, I mean one like your treasurer's job. In my mind, when we keep books for ourselves, that's a first-party situation and the accuracy and integrity of the accounting is nobody's business but our own. Second-party accounting would for a situation such as managing the finances of a close family member, where mutual trust is an essential part of the equation.
But as treasurer for your association, your accounting and reports. will be subject to scrutiny by officers and members of the association, plus probably lenders and other outsiders. In any such situation, accounting integrity should be guaranteed as much as possible by a system of internal controls, such as splitting responsibility for writing checks from the duty of recording those expenditures. Quicken's program offers absolutely no "internal controls" to assure that all transactions are recorded and reported properly. For beginners, any entry in Quicken can be deleted without a trace at any time. Anybody with access to the computer can make, change or delete any entry at any time for any reason, with no record of who did it or when or why. If any discrepancy ever arises in your association's accounting, you and the bookkeeper may be pointing fingers at each other, and even at other people; you will want a clear "audit trail" that will show who did what, when - and maybe why.
In olden pen-and-ink days, when I studied accounting and auditing, we learned to always use permanent ink so that erasures or changes would be evident. When necessary, we would "draw a single non-obliterating line through the incorrect entry, make the correct entry alongside, and initial the change". There's no way to create such a permanent record of corrections or other changes in Quicken. Even today, I could go back and change the payee on a 2008 entry in my system and there would be no evidence that the entry had not always read as it would now.
In my own books, this is not much of a problem. But if some third party were keeping books for MY company, I would want a more-secure accounting system than Quicken!
Since I'm not familiar with QuickBooks, I can't comment on your question about compatibility.
