How to Create Invoice Programmatically in Magento 2 [2024]

In Magento 2, apart from creating product and customer programmatically, you can also create invoice programmatically with ease when following the given guides in the Magento 2 create invoice programmatically topic.

Why do Magento 2 stores need to set up the program for creating the invoice? As you know, each time an invoice is created, that means an order is placed successfully and at the same time, Magento will notify you have earned the amount of money from the customer. However, by such a normal way, you will get mass notifications from the Magento 2 system as well as create the equivalent number of the invoices if your customer implements partial payment within the order. Therefore, the great solution is to form the invoice while there is no dependency on the total payment of order.

This post is a helpful guide to help you use this solution at its best. You will only have to go through two simple steps to solve the problem right away. Let’s get started!

Mageplaza brings you a step-by-step tutorial for that and here you are!

        parent::__construct($context);
    }

        $orderId = $this->_request->getParam('order_id');
        $order   = $this->_orderRepository->get($orderId);
        if ($order->canInvoice()) {
            $invoice = $this->_invoiceService->prepareInvoice($order);
            $invoice->register();
            $invoice->save();
            $transactionSave = $this->_transaction->addObject(
                $invoice
            )->addObject(
                $invoice->getOrder()
            );
            $transactionSave->save();
            $this->_invoiceSender->send($invoice);
    
            //send notification code
            $order->addCommentToStatusHistory(
                __('Notified customer about invoice #%1.', $invoice->getId())
            )
                ->setIsCustomerNotified(true)
                ->save();
}
}
