does some accounting stuff also.

Actually, they do much more than that. It's actually pretty impressive the
"modules" they provided. They've a nice download into Quicken (which is
great for billing hourly time), a "maintenance" module that seems pretty
flexible, support for various scheduling rules, and so on.

My club uses this, and they keep adding features we like. They take input
from us, and likely from all their other customers, and use it well.

I expect that this is overkill for a partnership, though. For our club
(flyingclub.org), it's terrific.
