📚 Usage

Creating an Invoice

use Turahe\Ledger\Models\Invoice;
use Turahe\Ledger\Services\LedgerService;

// Using the model directly
$invoice = Invoice::create([
    'model_id' => $user->id,
    'model_type' => User::class,
    'code' => 'INV-001',
    'total_invoice' => 1000.00,
    'due_date' => now()->addDays(30),
    'status' => 'pending',
    'currency' => 'IDR'
]);

// Using the service layer
$ledgerService = app(LedgerService::class);
$invoice = $ledgerService->createInvoice([
    'model_id' => $user->id,
    'model_type' => User::class,
    'code' => 'INV-001',
    'total_invoice' => 1000.00,
    'due_date' => now()->addDays(30)
]);

Adding Invoice Items

use Turahe\Ledger\Models\Invoice\Item;

$item = $invoice->items()->create([
    'name' => 'Product Name',
    'quantity' => 2,
    'unit_price' => 500.00,
    'total_price' => 1000.00,
    'description' => 'Product description'
]);

// Business logic methods
$subtotal = $item->getSubtotal();
$totalAmount = $item->getTotalAmount();
$discountPercentage = $item->getDiscountPercentage();

Processing Payments

use Turahe\Ledger\Models\Invoice\Payment;
use Turahe\Ledger\Enums\PaymentMethods;

$payment = $invoice->payments()->create([
    'amount' => 500.00,
    'payment_method' => PaymentMethods::E_WALLET_GOPAY,
    'payment_date' => now(),
    'status' => 'completed'
]);

// Check payment status
if ($payment->isCompleted()) {
    echo "Payment processed successfully";
}

Managing Vouchers

use Turahe\Ledger\Models\Voucher;

$voucher = Voucher::create([
    'model_id' => $user->id,
    'model_type' => User::class,
    'code' => 'VOUCHER-001',
    'total_value' => 500.00,
    'due_date' => now()->addDays(15),
    'status' => 'active',
    'currency' => 'IDR'
]);

// Business logic methods
if ($voucher->isExpired()) {
    echo "Voucher has expired";
}

$daysUntilExpiry = $voucher->getDaysUntilExpiry();
$formattedValue = $voucher->getTotalValueFormatted();

Using Query Scopes

use Turahe\Ledger\Models\Invoice;

// Find by code
$invoice = Invoice::byCode('INV-001')->first();

// Find by date range
$recentInvoices = Invoice::byDateRange(
    now()->subDays(30), 
    now()
)->get();

// Find by status
$pendingInvoices = Invoice::byStatus('pending')->get();

// Find by model
$userInvoices = Invoice::byModelType(User::class)
    ->byModelId($user->id)
    ->get();

Payment Methods

use Turahe\Ledger\Enums\PaymentMethods;

// Get methods by category
$qrisMethods = PaymentMethods::getByCategory('qris');
$eWalletMethods = PaymentMethods::getByCategory('e_wallet');

// Check method properties
if (PaymentMethods::E_WALLET_GOPAY->isDigital()) {
    echo "This is a digital payment method";
}

if (PaymentMethods::CASH->isInstant()) {
    echo "This is an instant payment method";
}
