A self-hosted invoicing and hour registration system for freelancers and small businesses.
Own your data - All data is stored as human-readable TOML files on your filesystem. No database lock-in, no proprietary formats. If something breaks, you can read and edit your invoices with any text editor.
Built-in audit trail - Every change is automatically committed to a local Git repository. Full version history, easy rollback, and optional sync to remote Git for backups.
Works offline - Runs entirely on your machine. No internet required, no cloud dependency, no subscription fees.
Fast - Pages load instantly. No waiting for cloud servers.
- Hour registration with conversion to invoices
- PDF invoice generation with UBL XML export
- Multi-entity support (manage multiple companies)
- CAMT053 bank statement import for payment matching
- VAT handling for NL, EU (reverse charge), and international exports
- Quarterly tax summaries
