More is required than a db schema; the double entry would have to be in app logic, permission model, aging, etc. Reports are nice, but in my experience I have always had to provide additional reporting on top of what is provided by an accounting system because the business had its own requirements. I see this being useful where you are trying to avoid a traditional accounting system because you willing to provide more customization.

You put it better than I can, voidmain0001! I've so often been frustrated by being unable to extend an accounting system to suit my needs.
