Open-source licences
Last updated: 16 October 2026
InvoiceFlow is proprietary software built on open-source components. We comply with their licences and credit them here.
Summary
The production build uses 658 open-source packages (inventory generated 2026-10-16). Nearly all are under permissive licences (MIT, Apache-2.0, ISC, BSD) that allow commercial, closed-source use with attribution. None are under a strong copyleft licence (GPL/AGPL) that would require us to publish our own source code.
