Customizing E-Invoices in Sales Pack

[yuri]

1. Create a file custom/Espo/Custom/Binding.php:

<?php
namespace Espo\Custom;

use Espo\Core\Binding\BindingProcessor;
use Espo\Core\Binding\Binder;
use Espo\Custom\EInvoice\MyPreparator;
use Espo\Modules\Sales\Tools\Invoice\EInvoice\Preparator;

class Binding implements BindingProcessor
{
    public function process(Binder $binder): void
    {
        $binder->bindImplementation(Preparator::class, MyPreparator::class);
    }
}

2. Create a file custom/Espo/Custom/EInvoice/MyPreparator.php:

<?php
namespace Espo\Custom\EInvoice;

use Einvoicing\Invoice as EInvoice;
use Einvoicing\Payments\Payment;
use Einvoicing\Payments\Card;

use Espo\Modules\Sales\Entities\Invoice;
use Espo\Modules\Sales\Tools\Invoice\EInvoice\Preparator;
use Espo\Modules\Sales\Tools\Invoice\EInvoice\DefaultPreparator;

class MyPreparator implements Preparator
{
    public function __construct(
        private DefaultPreparator $defaultPreparator,
    ) {}


    public function prepare(Invoice $invoice, string $format): EInvoice
    {
        $eInvoice = $this->defaultPreparator->prepare($invoice, $format);

        // Below, we set more fields to the prepared E-Invoice.
        // Everything below is just an example.

        /**
         * We assume that your Invoice entity type has the custom fields:
         * Payment Id, Payment MeansCode, etc.
         *
         * We use https://github.com/josemmo/einvoicing/ library.
         */

        $payment = new Payment();

        $payment->setId($invoice->get('cPaymentId'));
        $payment->setMeansCode($invoice->get('cPaymentMeansCode'));
        $payment->setMeansText($invoice->get('cPaymentMeansText'));

        $card = new Card();

        $card->setHolder($invoice->get('cPaymentCardHolder'));
        $card->setNetwork($invoice->get('cPaymentCardNetwork'));

        if ($invoice->get('cPaymentCardPan')) {
            $card->setPan($invoice->get('cPaymentCardPan'));
        }

        $payment->setCard($card);

        $eInvoice->setPayment($payment);

        return $eInvoice;
    }
