];You can store an Invoice in your database using the Eloquent Model: Finller\Invoice\Invoice.
Note
Don't forget to publish and run the migrations
Here is a full example:
use Finller\Invoice\Invoice;
use Finller\Invoice\InvoiceState;
use Finller\Invoice\InvoiceType;
// Let's say your app edit invoices for your users
$customer = User::find(1);
// Let's imagine that your users have purchased something in your app
$order = Order::find(2);
$invoice = new Invoice([
'type' => InvoiceType::Invoice,
'state' => InvoiceState::Draft,
'description' => 'A description for my invoice',
'seller_information' => config('invoices.default_seller'),
'buyer_information' => [
'name' => 'John Doe',
'address' => [
'street' => '8405 Old James St.Rochester',
'city' => 'New York',
'postal_code' => '14609',
'state' => 'New York (NY)',
'country' => 'United States',
],
'email' => 'john.doe@example.com',
'tax_number' => "FR123456789",
],
// ...
]);
$invoice->buyer()->associate($customer); // optionnally associate the invoice to any model
$invoice->invoiceable()->associate($order); // optionnally associate the invoice to any model
$invoice->save();
$invoice->items()->saveMany([
new InvoiceItem([
'unit_price' => Money::of(100, 'USD'),
'unit_tax' => Money::of(20, 'USD'),
'currency' => 'USD',
'quantity' => 1,
'label' => 'A label for my item',
'description' => 'A description for my item',
]),
]);This package provides a simple and reliable way to generate serial numbers automatically, such as "INV240001."
You can configure the format of your serial numbers in the configuration file. The default format is PPYYCCCC, where each letter has a specific meaning (see the config file for details).
When invoices.serial_number.auto_generate is set to true, a unique serial number is assigned to each new invoice automatically.
Serial numbers are generated sequentially, with each new serial number based on the latest available one. To define what qualifies as the previous serial number, you can extend the Finller\Invoice\Invoice class and override the getPreviousInvoice method.
By default, the previous invoice is determined based on criteria such as prefix, series, year, and month for accurate, scoped numbering.
In more complex applications, you may need to use different prefixes and/or series for your invoices.
For instance, you might want to define a unique series for each user, creating serial numbers that look like: INV0001-2400X, where 0001 represents the user’s ID, 24 the year and X the index of the invoice.
Note
When using IDs for series, it's recommended to plan for future growth to avoid overflow. Even if you have a limited number of users now, ensure that the ID can accommodate the maximum number of digits allowed by the serial number format.
When creating an invoice, you can dynamically specify the prefix and series as follows:
use Finller\Invoice\Invoice;
$invoice = new Invoice();
$invoice->configureSerialNumber(
prefix: "ORG",
serie: $buyer_id,
);In most cases, the format of your serial numbers should remain consistent, so it's recommended to set it in the configuration file.
The format you choose will determine the types of information you need to provide to configureSerialNumber.
Below is an example of the most complex serial number format you can create with this package:
$invoice = new Invoice();
$invoice->configureSerialNumber(
format: "PP-SSSSSS-YYMMCCCC",
prefix: "IN",
serie: 100,
year: now()->format('Y'),
month: now()->format('m')
);
$invoice->save();
$invoice->serial_number; // IN-000100-2410-0001The Invoice model has a toPdfInvoice() that return a PdfInvoice class.
You can stream the pdfInvoice instance as a response, or download it:
namespace App\Http\Controllers;
use App\Models\Invoice;
use Illuminate\Http\Request;
class InvoiceController extends Controller
{
public function show(Request $request, string $serial)
{
/** @var Invoice $invoice */
$invoice = Invoice::where('serial_number', $serial)->firstOrFail();
$this->authorize('view', $invoice);
return $invoice->toPdfInvoice()->stream();
}
public function download(Request $request, string $serial)
{
/** @var Invoice $invoice */
$invoice = Invoice::where('serial_number', $serial)->firstOrFail();
$this->authorize('view', $invoice);
return $invoice->toPdfInvoice()->download();
}
}The Invoice model provide a toMailAttachment method making it easy to use with Mailable
namespace App\Mail;
use App\Models\Invoice;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
class PaymentInvoice extends Mailable
{
use Queueable, SerializesModels;
/**
* Create a new message instance.
*/
public function __construct(
protected Invoice $invoice,
) {}
public function attachments(): array
{
return [
$this->invoice->toMailAttachment()
];
}
