E-invoicing for PHP and Laravel. Quittio creates, validates, reads and archives electronic invoices according to EN 16931, in any PHP 8.3 project and with a dedicated Laravel integration. ZUGFeRD, XRechnung and Peppol from one data model, checked with the official validators.

Valid e-invoices out. Quittio calculates totals and VAT, checks every invoice on seven levels against the official rules and renders the format your customer needs. *Laravel apps, other PHP frameworks and plain PHP pass invoice data to Quittio. Quittio calculates, validates on seven levels with the KoSIT validator and veraPDF, and outputs ZUGFeRD, XRechnung 3.0 and Peppol BIS 3.0 as well as PDF, HTML and JSON.* - ### Compliant Mandatory fields under German VAT law, tax presets for reverse charge, small businesses and intra-community supplies. A guard makes sure PDF and XML show the same data. - ### Validated Seven validation levels from data structure to PDF/A-3b. The official rules run in the KoSIT validator and veraPDF, locally and in your CI. - ### Developer-friendly A fluent API with sensible defaults, in plain PHP and in Laravel, there with fakes and assertions for Pest. A few lines instead of an XML project. **How it works** ## Create, output, validate, read. Real examples from the documentation. No hand-written XML, no rounding errors.

Only Quittio Managed, the invoice management in your database, is paid. ### **Which formats does Quittio support?** ZUGFeRD/Factur-X, XRechnung 3.0 (CII and UBL), Peppol BIS Billing 3.0, CII and UBL 2.1, plus PDF, HTML and JSON. ### **Does Quittio replace my accounting or tax adviser?** No. Quittio creates and validates invoices.

The API may still change until 1.0.0, and the legal texts of the country pack are being reviewed by a tax adviser. ### **What is the difference between Quittio and Quittio Managed?** Quittio creates the files.
