In this article, I will guide you on, how to add VAT and Company Number in invoice and shipment PDF in Magento 2?

Follow the below steps:

You need to override two models in custom extension.

I assume you know about how to override model.

Step 1

Create di.xml file in your module’s etc folder and put below code in it

<?xml version="1.0"?>
 
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <preference for="MagentoSalesModelOrderPdfInvoice" type="[vendername][modulename]ModelOrderPdfinvoice" />
 <preference for="MagentoSalesModelOrderPdfShipment" type="[vendername][modulename]OrderPdfshipment" />
</config>

Step 2

Create new model file Pdfinvoice.php in your Model/Order folder and put below code in it.

<?php
namespace [vendername][modulename]ModelOrder;
class Pdfinvoice extends MagentoSalesModelOrderPdfInvoice
{
 /**
 * Return PDF document
 *
 * @param array|Collection $invoices
 * @return Zend_Pdf
 */
 public function getPdf($invoices = [])
 {
 $this->_beforeGetPdf();
 $this->_initRenderer('invoice');

 $pdf = new Zend_Pdf();
 $this->_setPdf($pdf);
 $style = new Zend_Pdf_Style();
 $this->_setFontBold($style, 10);

 foreach ($invoices as $invoice) {
 if ($invoice->getStoreId()) {
 $this->_localeResolver->emulate($invoice->getStoreId());
 $this->_storeManager->setCurrentStore($invoice->getStoreId());
 }
 $page = $this->newPage();
 $order = $invoice->getOrder();
 /* Add image */
 $this->insertLogo($page, $invoice->getStore());
 /* Add address */
 $this->insertAddress($page, $invoice->getStore());
 /* Add head */
 $this->insertOrder(
 $page,
 $order,
 $this->_scopeConfig->isSetFlag(
 self::XML_PATH_SALES_PDF_INVOICE_PUT_ORDER_ID,
 MagentoStoreModelScopeInterface::SCOPE_STORE,
 $order->getStoreId()
 )
 );
 
 /* Add document text and number */
 $this->insertDocumentNumber($page, __('Invoice # ') . $invoice->getIncrementId());
 /* Add table */
 $this->_drawHeader($page);
 /* Add body */
 foreach ($invoice->getAllItems() as $item) {
 if ($item->getOrderItem()->getParentItem()) {
 continue;
 }
 /* Draw item */
 $this->_drawItem($item, $page, $order);
 $page = end($pdf->pages);
 }
 /* Add totals */
 $this->insertTotals($page, $invoice);
 if ($invoice->getStoreId()) {
 $this->_localeResolver->revert();
 }
 $this->_drawFooter($page);
 }
 $this->_afterGetPdf();
 return $pdf;
 }

 protected function _drawFooter(Zend_Pdf_Page $page)
 {
 $this->y = 50; 
 $page->setFillColor(new Zend_Pdf_Color_RGB(1, 1, 1));
 $page->setLineColor(new Zend_Pdf_Color_GrayScale(0.5));
 $page->drawRectangle(25, $this->y, 570, $this->y -30);
 $page->setLineWidth(0.5);

 $page->setFillColor(new Zend_Pdf_Color_RGB(0.1, 0.1, 0.1));
 $this->_setFontRegular($page, 10);
 $this->y -=16;
 $page->drawText(__('VAT # xxxxxxxx'), 220, $this->y, 'UTF-8');
 $page->drawText(__('Company # xxxxxxxxx'), 320, $this->y, 'UTF-8');

 } 
}

Step 3

Create another new model file Pdfshipment.php in your Model/Order folder and put below code in it.

<?php
namespace [vendername][modulename]ModelOrder;
class Pdfshipment extends MagentoSalesModelOrderPdfShipment
{
 /**
 * Return PDF document
 *
 * @param MagentoSalesModelOrderShipment[] $shipments
 * @return Zend_Pdf
 */
 public function getPdf($shipments = [])
 {
 $this->_beforeGetPdf();
 $this->_initRenderer('shipment');

 $pdf = new Zend_Pdf();
 $this->_setPdf($pdf);
 $style = new Zend_Pdf_Style();
 $this->_setFontBold($style, 10);
 foreach ($shipments as $shipment) {
 if ($shipment->getStoreId()) {
 $this->_localeResolver->emulate($shipment->getStoreId());
 $this->_storeManager->setCurrentStore($shipment->getStoreId());
 }
 $page = $this->newPage();
 $order = $shipment->getOrder();
 /* Add image */
 $this->insertLogo($page, $shipment->getStore());
 /* Add address */
 $this->insertAddress($page, $shipment->getStore());
 /* Add head */
 $this->insertOrder(
 $page,
 $shipment,
 $this->_scopeConfig->isSetFlag(
 self::XML_PATH_SALES_PDF_SHIPMENT_PUT_ORDER_ID,
 MagentoStoreModelScopeInterface::SCOPE_STORE,
 $order->getStoreId()
 )
 );
 /* Add document text and number */
 $this->insertDocumentNumber($page, __('Packing Slip # ') . $shipment->getIncrementId());
 /* Add table */
 $this->_drawHeader($page);
 /* Add body */
 foreach ($shipment->getAllItems() as $item) {
 if ($item->getOrderItem()->getParentItem()) {
 continue;
 }
 /* Draw item */
 $this->_drawItem($item, $page, $order);
 $page = end($pdf->pages);
 }
 if ($shipment->getStoreId()) {
 $this->_localeResolver->revert();
 }
 $this->_drawFooter($page);
 }
 $this->_afterGetPdf();
 return $pdf;
 }

 protected function _drawFooter(Zend_Pdf_Page $page)
 {
 $this->y = 50; 
 $page->setFillColor(new Zend_Pdf_Color_RGB(1, 1, 1));
 $page->setLineColor(new Zend_Pdf_Color_GrayScale(0.5));
 $page->drawRectangle(25, $this->y, 570, $this->y -30);
 $page->setLineWidth(0.5);

 $page->setFillColor(new Zend_Pdf_Color_RGB(0.1, 0.1, 0.1));
 $this->_setFontRegular($page, 10);
 $this->y -=16;
 $page->drawText(__('VAT # xxxxxxxxx'), 220, $this->y, 'UTF-8');
 $page->drawText(__('Company # xxxxxxxxx'), 320, $this->y, 'UTF-8');

 }
}
