quittio/core

Country-neutral core of Quittio: EN 16931 data model, calculation, profiles, CII and UBL writers and readers, ZUGFeRD/Factur-X PDF/A-3 and validation. Usable without Laravel: it runs in any PHP 8.3 application, with Symfony, another framework or none.

With the core you create ZUGFeRD / Factur-X invoices (PDF/A-3 with embedded CII XML), Peppol BIS Billing 3.0 and plain UBL or CII XML, validate them against the rules of EN 16931 and read incoming e-invoices. For XRechnung and the German VAT rules, add the country pack Germany:

composer require quittio/core quittio/country-de

Most applications install everything at once with composer require quittio/quittio (core, Laravel integration and the country pack Germany).
