README

Modern, fully typed invoicing toolkit for Laravel applications with discount, tax, currency and PDF engines that work together out of the box.

Highlights

• Value-object based models and enums for rock-solid invoice data.
• Dedicated pricing, tax, discount and numbering engines with sensible defaults.
• Built-in DomPDF integration with publishable Blade templates.
• Currency formatter, units and helpers that keep calculations precise.
• Batteries-included facade: Invoice::make(), Invoice::calculate(), Invoice::stream() and more.

Requirements

• PHP 8.2+
• Laravel 10.x, 11.x or 12.x
• barryvdh/laravel-dompdf (installed automatically)

Install

composer require dgtlinf/invoice

Publish the configuration or default PDF view if you need to customise them:

php artisan vendor:publish --tag="invoice-config"
php artisan vendor:publish --tag="invoice-views"

Quick usage

use Dgtlinf\Invoice\Facades\Invoice;
use Dgtlinf\Invoice\Models\{LineItem, Party, PaymentDetails, Tax, Quantity, Money};
use Dgtlinf\Invoice\Support\{Currency, UnitType, InvoiceType};

Route::get('/invoice', function () {
    $currency = Currency::fromConfig();

    $seller = new Party(name: 'DEMO COMPANY ACME LTD', address: 'Main Street 123456', taxId: '123456789');
    $buyer = new Party(name: 'Acme, Inc.', address: '1234 Goto street', taxId: '11-2222222');

    $items = [
        new LineItem(
            description: 'Monthly retainer fee',
            quantity: Quantity::from(1),
            unitPrice: Money::from(15000, $currency),
            tax: new Tax('VAT', 0, Money::from(0, $currency)),
            unit: UnitType::MONTH
        ),
        // ...more items, discounts, etc.
    ];

    $items = Invoice::applyItemDiscounts($items);

    $payment = new PaymentDetails(
        bankName: 'GREAT BANK OF WORLD, London, UK',
        accountNumber: '000-000000000-11',
        iban: 'UK000000000000000'
    );

    $invoice = Invoice::make([
        'number' => 'INV0001',
        'type' => InvoiceType::INVOICE,
        'seller' => $seller,
        'buyer' => $buyer,
        'items' => $items,
        'amountPaid' => Money::from(0, $currency),
        'paymentDetails' => $payment,
        'note' => 'The VAT calculation date is the date of supply.',
        'dueAt' => now()->addDays(7),
    ]);

    return Invoice::stream(Invoice::calculate($invoice));
});
