1)Automatic Inventory Control
Inventory control is carefully built in as the core of eCommerce System. Just set the inventory balance for each of your products and your shop will automatically manage the inventory for you.
Customers will not be able to purchase a product when inventory is at zero. Telling your customers 'Sorry, we are out of stocks, here is a refund' will be a thing of the past.
2)Automatic Cart Expiry
All products added to customer's shopping cart has an expiry date. If the product is not purchased within a certain period, it will be automatically removed and the added back to the inventory. So you do not need to worry about inventory running out because it is stuck in abandoned shopping carts.
