README

A modern PHP 8.1+ library for creating Factur-X electronic invoices, compatible with Chorus Pro. Uses mPDF to generate PDF/A-3 documents.

• Create a Factur-X document
• Validate against official XSD schemas
• Read a Factur-X document (coming soon)

Installation

composer require stann/factur-x

Usage

Create a Factur-X document

Using the builder (recommended):

<?php

use Stann\FacturX\AppendixParts\ExchangedDocument;
use Stann\FacturX\AppendixParts\MonetarySummation;
use Stann\FacturX\AppendixParts\TradeParty;
use Stann\FacturX\AppendixParts\TypeCode;
use Stann\FacturX\CrossIndustryInvoiceBuilder;
use Stann\FacturX\FacturX;
use Stann\FacturX\ValueObjects\CountryCode;
use Stann\FacturX\ValueObjects\VATNumber;

$invoice = CrossIndustryInvoiceBuilder::minimum()
    ->withDocument(new ExchangedDocument('F0003', TypeCode::INVOICE, new DateTimeImmutable()))
    ->withSeller(new TradeParty('Stann', '34261828837536', CountryCode::FRANCE, new VATNumber('FR520000000')))
    ->withBuyer(new TradeParty('Mairie de Toulouse', '10881392400937', CountryCode::FRANCE, new VATNumber('FR980000000')))
    ->withAmounts(new MonetarySummation('EUR', 100.00, 120.00, 120.00))
    ->withBuyerReference('1004')        // Optional, for Chorus Pro "Service Exécutant"
    ->withBuyerOrderReference('BDC001') // Optional, for Chorus Pro "Engagement Juridique"
    ->build();

$facturX = (new FacturX())->createFile(
    fopen(__DIR__ . '/assets/facture.pdf', 'rb'),
    $invoice,
);

Or using the constructor directly:

$invoice = new CrossIndustryInvoice(
    document: new ExchangedDocument('F0003', TypeCode::INVOICE, new DateTimeImmutable()),
    sellerTradeParty: new TradeParty('Stann', '34261828837536', CountryCode::FRANCE, new VATNumber('FR520000000')),
    buyerTradeParty: new TradeParty('Mairie de Toulouse', '10881392400937', CountryCode::FRANCE, new VATNumber('FR980000000')),
    monetarySummation: new MonetarySummation('EUR', 100.00, 120.00, 120.00),
    buyerReference: '1004',
    buyerOrderReference: 'BDC001',
);

Available profiles

The builder provides factory methods for each Factur-X profile:

CrossIndustryInvoiceBuilder::minimum();   // Simplest profile
CrossIndustryInvoiceBuilder::basicWL();   // Basic Without Lines
CrossIndustryInvoiceBuilder::basic();     // With invoice lines
CrossIndustryInvoiceBuilder::en16931();   // European standard
CrossIndustryInvoiceBuilder::extended();  // Full features

Note: withBuyerContractReference() is only available for BASIC_WL and higher profiles.

Validation

Validate your document against official XSD schemas:

<?php

use Stann\FacturX\FacturX;
use Stann\FacturX\Schema;

$facturX = new FacturX();

// Throws InvalidXMLSchema with LibXMLError[] on failure
$facturX->validate($invoice->toXml(), Schema::MINIMUM);

// Returns boolean
$facturX->isValid($invoice->toXml(), Schema::MINIMUM);

// Returns LibXMLError[]
$errors = $facturX->getValidationErrors($invoice->toXml(), Schema::MINIMUM);

Available schemas

• Schema::MINIMUM
• Schema::BASIC_WL
• Schema::BASIC
• Schema::EN16931
• Schema::EXTENDED
