Cococart allows you manage your inventory to avoid issues of overselling. Once an order is placed by a customer, inventory is reserved for that order while waiting for their payment.
If the customer does not complete payment, you may reject their order and the inventory will be released for other customers to order. Customers will receive a notification that their order has been rejected.
With the exception of automated payment methods in certain countries (like Automated PayNow), sellers will have to manually approve or reject orders by themselves.
