Had our friend over to look at the books tonight. Just about every operation we attempted in GNUCash (mostly reports, exports, etceteras) failed, either just did nothing or produced reports with $0.00 everywhere. We wound up having to give her screenshots to work with! Given that Ledger SMB is still a work-in-process I'm thinking I'll just have to give in to proprietary-land and buy a copy of Quickbooks to run for the company.
