Open source
We are big on open source
Financica is built on open standards, so we build in the open too. The e-invoicing and accounting plumbing we needed did not exist as reusable libraries, so we wrote it and released it. Everything below is free to use under a permissive licence, maintained by our team, and lives on GitHub.
