What sort of things are you wanting to integrate? I ran the accounting for my church for six months. I absolutely HATED their accounting system (almost gave them Sage100) to make my life easier but decided to leave the position instead. And while I did hate the PR, AP, BR and General ledger, I did appreciate the membership database. Had I stuck with it, I feel Sage would have worked very nicely. I would have posted the contributions to the membership database, then simply rekeyed the JE (less than 10 lines each week) for these amounts into Sage. Church software is just like any other vertical. The vertical (membership database) is great, everything else suffers.
