Been trying to find an open source accounting software that also handles purchase orders and invoices. The ones I've found are full-on slopified.

I took a 2nd look at GnuCash which doesn't explicitly support POs or invoices.

Well, their first LLM commit was this past April, making their latest release v5.16 slop.

GnuCash is my best option so I'm going to fork v5.15 (latest clean release) to add PO/Invoice support. Will manually handle POs and invoices in the short term.
