Hello, I have done some searches, and come up with very little on the subject of checkbooks. My reason has to do with a small business (publishing and mailing a periodical) I run, previously having done the checkbook in an old MS application called works. I maintain my mailing list in Filemaker. I have moved to a G4 mac from an older machine, and fortunately, I suppose, can no longer run works and have moved to MS Office. I have always wanted to do all of my business record keeping in Filemaker, as I felt I could integrate mailing list, revenue, and expense functions in one application that could greatly automate my tax preparation challenge. I do not find much on checkbooks here, which surprises me. Does that mean you are purchasing something that you think works better than Filemaker?
