GnuCash vs SolidInvoice
A side-by-side editorial comparison of GnuCash and SolidInvoice — release velocity, themes, recent moves, and the top alternatives to consider.
GnuCash vs SolidInvoice: at a glance
What is GnuCash?
GnuCash 5.17 is another bugfix list, with a real capital-gains fix tucked inside.
GnuCash 5.17 continues the 5.x stable series, and the announcement again leads with numbered bug reports closed since the previous release. The notable work sits further down: the Show Lots dialog now handles stock splits so capital gains use the correct basis, transactions voided without a reason can now be unvoided, and charts gain global preferences and clearer tooltips. AqBanking import can also bring in pending transactions.
What is SolidInvoice?
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.

GnuCash 5.17 is another bugfix list, with a real capital-gains fix tucked inside.
◆ Current state
GnuCash 5.17 continues the 5.x stable series, and the announcement again leads with numbered bug reports closed since the previous release. The notable work sits further down: the Show Lots dialog now handles stock splits so capital gains use the correct basis, transactions voided without a reason can now be unvoided, and charts gain global preferences and clearer tooltips. AqBanking import can also bring in pending transactions.
◆ Where it's heading
The rhythm holds at about one release per quarter, and improvements continue to arrive inside bugfix lists rather than as announced features. Chart interaction has become the most active area in this release, with several preferences added at once. Nothing here points to a 6.x line. This is a mature application working through its backlog steadily.
◆ Prediction
Expect 5.18 around the end of the year, following the quarterly pattern and last December's release. The entries give no sign of a major version.
SolidInvoice
5.0FINANCE
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
◆ Current state
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.
◆ Where it's heading
After the large 3.0 release in June, work has moved to hardening: upgrade paths, packaging (Snap, static PHP builds) and correctness in payments and reporting. The mention of MCP payments shows AI-agent access is already wired into billing, though the entries don't detail it.
◆ Prediction
Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
