The business process starts with the customer creating the order request.
The system checks the database for item availability. If the item is not available, the
customer is given the choice of whether they want to buy a similar item or cancel
the order. If the item is in stock, the customer gets the review of the order. Then
they can proceed to payment or cancel the order within 1 hour; otherwise, the order
will be canceled automatically. In the next step, the customer pays for the order,
and the payment is being verified. In case of failure, the customer is given a
chance to retry the payment. If the payment is successful, the system generates
the printed bill, and the e-shop employee prepares the order for sending. Then the
order and the invoice are given to the parcel service for delivery.
