Installation

$ composer require sander-van-hooft/laravel-invoicable

You can publish the migration with:

$ php artisan vendor:publish --provider="SanderVanHooft\Invoicable\InvoicableServiceProvider" --tag="migrations"

After the migration has been published you can create the invoices and invoice_lines tables by running the migrations:

$ php artisan migrate

Optionally, you can also publish the invoicable.php config file with:

$ php artisan vendor:publish --provider="SanderVanHooft\Invoicable\InvoicableServiceProvider" --tag="config"

This is what the default config file looks like:

return [
    'default_currency' => 'EUR',
    'default_status' => 'concept',
    'locale' => 'nl_NL',
];

If you’d like to override the design of the invoice blade view and pdf, publish the view:

$ php artisan vendor:publish --provider="SanderVanHooft\Invoicable\InvoicableServiceProvider" --tag="views"

You can now edit receipt.blade.php in <project_root>/resources/views/invoicable/receipt.blade.php to match your style.

Usage

Money figures are in cents!

Add the invoicable trait to the Eloquent model which needs to be invoiced (typically an Order model):

use Illuminate\Database\Eloquent\Model;
use SanderVanHooft\Invoicable\IsInvoicable\IsInvoicableTrait;

class Order extends Model
{
    use IsInvoicableTrait; // enables the ->invoices() Eloquent relationship
}

Now you can create invoices for an Order:

$order = Order::first();
$invoice = $order->invoices()->create([]);

// To add a line to the invoice, use these example parameters:
//  Amount:
//      121 (€1,21) incl tax
//      100 (€1,00) excl tax
//  Description: 'Some description'
//  Tax percentage: 0.21 (21%)
$invoice = $invoice->addAmountInclTax(121, 'Some description', 0.21);
$invoice = $invoice->addAmountExclTax(100, 'Some description', 0.21);

// Invoice totals are now updated
echo $invoice->total; // 242
echo $invoice->tax; // 42

// Set additional information (optional)
$invoice->currency; // defaults to 'EUR' (see config file)
$invoice->status; // defaults to 'concept' (see config file)
$invoice->receiver_info; // defaults to null
$invoice->sender_info; // defaults to null
$invoice->payment_info; // defaults to null
$invoice->note; // defaults to null

// access individual invoice lines using Eloquent relationship
$invoice->lines;
$invoice->lines();

// Access as pdf
$invoice->download(); // download as pdf (returns http response)
$invoice->pdf(); // or just grab the pdf (raw bytes)

// Handling discounts
// By adding a line with a negative amount.
$invoice = $invoice->addAmountInclTax(-121, 'A nice discount', 0.21);

// Or by applying the discount and discribing the discount manually
$invoice = $invoice->addAmountInclTax(121 * (1 - 0.30), 'Product XYZ incl 30% discount', 0.21);

// Convenience methods
Invoice::findByReference($reference);
Invoice::findByReferenceOrFail($reference);
$invoice->invoicable() // Access the related model
