Invoicing tools have to cover a practical mix of client records, invoice creation, payments, recurring billing, and sometimes time tracking or quotes. This June 2026 view uses ToolVitals data on health score, shipping score, ToolVitals score, GitHub stars, licensing, and openness to compare open/source-visible invoicing options without treating popularity alone as quality.
The ranking includes only open/source-visible tools and sorts by ToolVitals score first, with GitHub stars used as a secondary popularity signal when scores are tied. Every listed tool is labeled OSI-approved OSS, and the license labels are shown exactly as reported in the data.
