Quittio

E-invoicing for Laravel. Quittio creates, validates, reads and renders electronic invoices based on the European standard EN 16931 – ZUGFeRD/Factur-X, XRechnung, UBL and Peppol BIS from one data model.

Get started Formats and profiles

---

Germany is the first market; everything country-specific lives in country packs, so the core stays country-neutral.

Status: version 0.1.0 in preparation. Not released yet; APIs may still change, and the legal wording of the country packs must be confirmed by a tax adviser.

Packages

Package	Purpose
quittio/core	Country-neutral core: EN 16931 data model, calculation, profiles, CII and UBL writers/readers, ZUGFeRD/Factur-X PDF/A-3, validation. Usable without Laravel.

quittio/country-de	Country pack for Germany: UStG mandatory fields, tax presets, XRechnung profiles and BR-DE rules, DIN 5008 letter layouts.
