I am looking for a small business acctg pkg for use with a volunteer
organization.  The finance officer tells me that they operate under the
cash vs accrual method of accounting. First, let me say that I've had the
obligatory 6hrs college acctg, but some years ago.  I thumbed through an
old issue of PC Computing recently, and noticed that some pkgs were listed
as being able to use one/theother/both systems, but at that time, I wasn't
trying to solve this riddle, so of course, that copy is now history.  

My questions are, 1) what is the difference in procedures, methodologies,
etc., between cash, and accrual, and how does it affect using the software?
2) What pkg(s) can you recommend.  Since we're going to have to buy 50+
copies, I'd like to be able to keep the cost down to <$250 per.  Any
recommendations?  Thanx!!
