I am a new treasurer (new to QB) trying to set up QB Non-Profit to work with our church. We have 3 separate accounts (which could be considered different funds - operating, building, special mission), with the operating account having a special poor fund under it.

I'm trying to figure out how to set up QB for this. I see there are Classes, and there's an Item List. To me they look about the same, and I can't figure out what the difference is between them. I suppose I'm looking more for the concept - trying to see what the best way is to set up what I think would be called "Fund Accounting"?

No, I'm not an accountant or anything close, but a volunteer currently trying to decipher how to set this up. So when you answer, I would really appreciate an entry level explanation.
