Usage

Invoices

use SimpleParkBv\Invoices\Models\Invoice;
use SimpleParkBv\Invoices\Models\InvoiceItem;
use SimpleParkBv\Invoices\Models\Buyer;

$invoice = Invoice::make()
    ->series('2024')
    ->sequence(1)
    ->date('2024-01-15')
    ->language('nl')
    ->buyer([
        'name' => 'John Doe',
        'email' => 'john@example.com',
        'address' => '123 Main St',
        'city' => 'Amsterdam',
        'postal_code' => '1000 AA',
    ])
    ->items([
        InvoiceItem::make([
            'title' => 'Product Name',
            'description' => 'Product description',
            'quantity' => 2,
            'unit_price' => 50.00,
            'tax_percentage' => 21.0,
        ]),
    ]);

return $invoice->download(); // or ->stream() for browser preview

Invoice Numbers: Combine series() and sequence() to generate formatted invoice numbers (e.g., "2024.00000123").

Discounts: Use negative unit_price values for discount items (quantities must be positive).

Expected Totals: Set an expected total with expectedTotal(100.00) for validation. When the invoice is rendered, if the expected total differs from the calculated total, an error will be logged.

Usage Receipts

use SimpleParkBv\Invoices\Models\UsageReceipt;
use SimpleParkBv\Invoices\Models\UsageReceiptItem;
use SimpleParkBv\Invoices\Models\Buyer;

$receipt = UsageReceipt::make()
    ->date('2024-01-15')
    ->language('nl')
    ->title('Custom Title') // optional, falls back to translation
    ->documentId('DOC-12345')
    ->userId('USER-001')
    ->buyer([
        'name' => 'John Doe',
        'email' => 'john@example.com',
    ])
    ->items([
        UsageReceiptItem::make([
            'user' => 'John Doe',
            'identifier' => 'ABC123',
            'start_date' => '2024-01-15 10:00:00',
            'end_date' => '2024-01-15 12:00:00',
            'category' => 'Premium',
            'price' => 12.50,
        ]),
    ])
    ->note('Optional note for the receipt');

return $receipt->download(); // filename is locale-aware

Locale-Aware Filenames: The package generates filenames based on the selected language (e.g., gebruiksbevestiging-2026-01-19-14-30-00.pdf for Dutch).

Common Features

Both Invoice and UsageReceipt support:

• Fluent interface and array-based creation
• Data arrays: Invoice::make($data) or UsageReceipt::make($data)
• Serialization: ->toArray() for JSON/API responses
• Validation: Automatic validation before rendering, or manual with ->validate()
• Output: ->download(?string $filename) or ->stream(?string $filename)
• Custom templates: ->template('custom.template')
• Custom logos: ->logo('/path/to/logo.png')
• Date parsing: Accepts Carbon instances or strings (parsed with Carbon::parse())

Creating from Arrays

$invoice = Invoice::make([
    'buyer' => ['name' => 'John Doe', 'email' => 'john@example.com'],
    'date' => '2024-01-15',
    'series' => '2024',
    'sequence' => 1,
    'items' => [
        ['title' => 'Product', 'quantity' => 1, 'unit_price' => 100.00, 'tax_percentage' => 21.0],
    ],
]);

$receipt = UsageReceipt::make([
    'buyer' => ['name' => 'Jane Doe'],
    'date' => '2024-01-15',
    'document_id' => 'DOC-001',
    'user_id' => 'USER-001',
    'items' => [
        ['user' => 'Jane Doe', 'identifier' => 'XYZ', 'start_date' => '2024-01-15 10:00', 'end_date' => '2024-01-15 12:00', 'category' => 'Basic', 'price' => 10.00],
    ],
]);

Validation Requirements

Invoices must have:

• A buyer with at least a name
• At least one item with: non-empty title, quantity > 0, unit price, tax percentage (0-100 or null)

Usage Receipts must have:

• A buyer with at least a name
• At least one item with: user, identifier, start date, end date, category, and price

Development

composer install
./vendor/bin/sail up -d
./vendor/bin/sail phpunit
./vendor/bin/phpstan analyse
./vendor/bin/pint

Troubleshooting

Validation fails: Ensure buyer and items meet requirements above.

PDF generation fails: Verify translations exist for the selected language and logo path is valid.

Language not supported: Supported languages are detected from resources/lang/. Add custom translations by publishing the language files.
