Best Way to Add an Automatic Invoice Generation Feature in Magento?

[packagingsb43b]

I run a custom packaging business called Packaging San Diego, where we offer a variety of custom food packaging, cardboard boxes, retail boxes, rigid boxes, kraft boxes, paper shopping bags, wrapping paper, and labels. Our customers range from small bakeries to large retail brands, and many of them request payment invoices for their bulk orders.

Right now, we manually send invoices through email, but I’d love to add an automatic invoice generation feature to our Magento store. The idea is to let customers generate and download invoices instantly from their order history with just one click.

I’ve explored a few options like:

Magento Invoice Extensions: Some offer useful features but come with a learning curve or high costs.
Payment Gateway Integrations (Stripe, PayPal, etc.): Good for online payments but not ideal for offline transactions.
Custom PDF Invoice Generation (MPDF, TCPDF, domPDF): Might be a good solution but requires development effort.

Ideally, the solution should:
Auto-fill customer details and order information.
Generate a clean PDF invoice with branding.
Provide a "Download Invoice" button in the customer account section.
Work seamlessly with Magento's order management system.

For those who have implemented something similar, what’s the best approach? Would you recommend a specific Magento extension or a custom-built solution? Any advice would be greatly appreciated!

Best Way to Add an Automatic Invoice Generation Feature in Magento

Hi packagingsb43b,

Since you're running a custom packaging business and dealing with bulk orders, automating invoice generation in Magento is a great step toward efficiency. Based on your requirements, here are the best approaches you can consider:

1. Magento Invoice Extensions

There are several Magento 2 extensions that offer automatic PDF invoice generation, allowing customers to download invoices from their account. Some of the best options include:

• Mageplaza PDF Invoice – Customizable invoice templates, automatic generation, and branding options.
• Fooman PDF Customizer – Great for adding logos and custom invoice designs.
• Amasty PDF Customizer – Advanced branding and invoice customization.

These extensions integrate well with Magento’s order management system and provide the "Download Invoice" button in the customer dashboard.

2. Custom PDF Invoice Generation

If you prefer a more tailored approach, you can develop a custom module using MPDF, TCPDF, or domPDF to generate invoices dynamically. This requires development effort but gives you complete control over branding, design, and invoice fields. You can:

• Use Magento’s built-in invoice system and override the default template.
• Add a "Download Invoice" button to the customer order history page.
• Auto-generate and email invoices upon order completion.

3. Payment Gateway Integrations

Since you also deal with offline transactions, relying on Stripe/PayPal invoices isn’t the best standalone solution. However, if you process online payments, enabling automatic invoice generation through these gateways could complement your existing system.

Recommendation

If you want a quick and cost-effective solution, a Magento extension like Mageplaza PDF Invoice is your best bet. However, if you need full customization and control, a custom-built solution using TCPDF or MPDF would be ideal.

Let me know if you need guidance on implementation!

Best,

In magento or most ecommerce, invoice is usually generated after order and payment have been confirmed. 

If you use an offline payment method like 'check/money order', you can set the payment instruction in admin, the instruction will be displayed on checkout page, and attached to the order email. After customers sent out payment following the instruction, you can then generate invoice on the order to mark payment has been completed.

Obviously every business runs on it's own way and maybe your customers requires invoice before the payment, if you need custom built solution, just send me a message, I'm happy to help!

Adding an automatic invoice generation feature in Magento can streamline your order processing and improve efficiency. Here are the best ways to implement it:

---

1. Use Magento’s Built-in Settings (Limited)

Magento allows you to manually generate invoices, but automation requires additional customization or extensions.

Steps to Manually Enable Invoice Generation

1. Go to Stores > Configuration > Sales > Sales Emails.

2. Enable Invoice Emails to notify customers after an invoice is generated.

3. You still need to manually generate invoices in Sales > Orders.

   🔹 Limitation: This doesn’t automate invoice creation, only notifications.

   ---

   2. Use a Magento Extension (Easiest Way)

   Several Magento extensions can automate invoice generation. Some popular ones:

   • Amasty Automatic Invoice

   • Mageplaza Auto Invoice & Shipment

   • Fooman PDF Customizer

     Steps to Install an Extension

     1. Purchase and install the extension via Composer or Magento Marketplace.

     2. Configure settings in Stores > Configuration > Sales.

     3. Set rules for automatic invoicing (e.g., payment status, order total).

        🔹 Pros: Quick setup, advanced features, and customization.
        🔹 Cons: Some extensions require a paid license.

        ---

        3. Custom Magento Module (For Full Control)

        If you want a tailored solution, you can create a custom module.

        Steps to Develop a Custom Auto-Invoice Module

        1. Create a new module in app/code/YourVendor/AutoInvoice.

        2. Use an event observer to trigger invoice creation when an order is placed.

           • Listen to the sales_order_place_after or sales_order_payment_pay event.

           • Generate an invoice programmatically:

             public function execute(\Magento\Framework\Event\Observer $observer)
             {
             $order = $observer->getEvent()->getOrder();
             if ($order->canInvoice()) {
             $invoice = $order->prepareInvoice();
             $invoice->setRequestedCaptureCase(\Magento\Sales\Model\Order\Invoice::CAPTURE_ONLINE);
             $invoice->register();
             $invoice->save();
             $order->addStatusHistoryComment('Invoice created automatically.');
             $order->save();
             }
             }

             4. Automate via Magento API (For Integration)

             If you're using an external system, you can use the Magento API to generate invoices.

             Example API Call (REST)

             sh

             CopyEdit

             curl -X POST "https://yourstore.com/rest/V1/invoices" \ -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \ -H "Content...

             🔹 Pros: Best for third-party ERP or accounting integration.
             🔹 Cons: Requires API setup and authentication.

             Which Method Should You Choose?

             ✅ For a quick solution → Install an extension.
             ✅ For a custom approach → Develop a module.
             ✅ For integration with external tools → Use Magento’s API.
