#e-invoicing
Best open-source e-invoicing apps and tools (2026)
These apps create, send and archive invoices, and many also cover quotes, payment records and expense tracking. When choosing one, check which e-invoicing formats it produces, such as Factur-X, FatturaPA, UBL 2.1 or Peppol, since that decides whether it meets the rules where you work. InvoiceShelf is a self-hosted invoicing app for freelancers, covering invoices, payments and expenses. Invio is a slim app that generates Factur-X, FatturaPA and UBL 2.1 e-invoices. TimeTracker combines timers, projects and PDF invoices with Peppol e-invoicing.
