Build a Fully Working IRB e-Invoice Integration in 10 Days

Malaysia’s Inland Revenue Board (IRB) now requires businesses to submit e-Invoices using the MyInvois platform. Over the next 10 days, you’ll build a fully working IRB e-invoice integration in Laravel — from generating UBL-compliant XML to digitally signing and submitting to IRBM.

Today’s Goal: Project Setup + Base Structure

To prepare for UBL generation and API submission, we’ll:

🎯 Create a clean Laravel project
📁 Create folder structure for IRB-related classes
🔐 Store IRB certificate and private key
⚙️ Add base config to .env and config/certs.php

Step 1: Create a New Laravel Project


composer create-project laravel/laravel irb-einvoice
cd irb-einvoice

Or use your existing Laravel app.

Step 2: Create Base Folders for IRB Integration


mkdir -p app/Services/IRB
mkdir -p storage/certs

Step 3: Add IRB Certificate and Private Key

Put your IRBM client certificate and private key here:


storage/certs/
├── irb_client_cert.pem
├── irb_client_key.pem

Tip: Use SSLShopper to convert .p12 files into .pem format.

Step 4: Create Basic Cert Config

Create config/certs.php:

return [
    'irb_client_cert' => storage_path('certs/irb_client_cert.pem'),
    'irb_client_key' => storage_path('certs/irb_client_key.pem'),
    'irb_client_key_passphrase' => env('IRB_CLIENT_KEY_PASSPHRASE', ''),
];

Update your .env file:


IRB_CLIENT_KEY_PASSPHRASE=""

Step 5: Create Your First IRB Service Class

Create app/Services/IRB/IRBXmlSignatureService.php:


namespace App\Services\IRB;

use Exception;

class IRBXmlSignatureService
{
    private string $certPem;
    private string $pkeyPem;
    private ?string $pkeyPassphrase;

    public function __construct()
    {
        $this->certPem = file_get_contents(config('certs.irb_client_cert'));
        $this->pkeyPem = file_get_contents(config('certs.irb_client_key'));
        $this->pkeyPassphrase = config('certs.irb_client_key_passphrase');

        if (!$this->certPem || !$this->pkeyPem) {
            throw new Exception('IRB certificate or key not found.');
        }
    }

    // Signature method will be added later
}

Up Next: Generate UBL 2.1-Compliant Invoice XML

In Day 2: Generate UBL XML Structure for IRB, we’ll build a generator that creates IRB-compliant invoice XML using namespaces, strict node ordering, and invoice details.
