Invoice sent, invoice paid: settled.
Quittio comes from the German “Quittung” (receipt) and “quitt sein” (to be settled). We want e-invoices in Laravel to be as natural as sending mail.
How we work
Specification before code
Every rule is described and backed by a source before it is built.
Official validators
KoSIT and veraPDF decide whether an invoice is valid, not us.
Tax review
Legal texts and defaults are reviewed by a tax adviser. Open questions are listed publicly in the README.
Open core
Creating and validating is free. Managed funds the ongoing maintenance of the rules.
Who is behind it
Quittio is developed and run by Niklas Forst (Niklas Forst – Softwareentwicklung, Ettinghausen, Germany; see the imprint). Questions about using Quittio belong on GitHub; everything else goes to [email protected].
