🧱 Database Tables

🧩 Making a Model Stockable

Use the Stockable trait on any Eloquent model.

use VivekMistry\InventoryCore\Traits\Stockable;

class Product extends Model
{
    use Stockable;
}

That’s it 🎉

🧮 Basic Usage

Add Stock

$product->addStock(100);

With warehouse

$product->addStock(50, ['reason' => 'Initial stock'], warehouseId: 1);

➖ Reduce Stock

$product->reduceStock(5);

🔒 Reserve Stock (Cart / Order)

Prevents overselling.

$product->reserveStock(2);

With warehouse:

$product->reserveStock(2, warehouseId: 1);

🔓 Release Reserved Stock

$product->releaseStock(2);

📊 Stock Helpers

$product->availableStock(); // quantity - reserved
$product->reservedStock();

🏬 Warehouses

Warehouses are optional but recommended.

InventoryWarehouse::create([
    'name' => 'Main Warehouse',
    'code' => 'MAIN',
    'is_default' => true,
]);

If no warehouse is provided, the default warehouse is used.

🚨 Low Stock Detection Triggered automatically when stock falls below threshold.

'low_stock_threshold' => 5,

Listen to the event:

use InventoryCore\Events\LowStockDetected;

Event::listen(LowStockDetected::class, function ($event) {
    // Send email, Slack, notification, etc.
});

## 🧪 Example Flow (Real-World)
$product->addStock(100);
$product->reserveStock(10);   // Cart
$product->availableStock();   // 90
$product->releaseStock(5);    // Cart cancelled
$product->reduceStock(5);
