This is the admin application that can be used by the delivery company owners and their courier employees.
Admin can see all of the orders, can decide to accept, reject or change the status of the order to anything they want. Admin can also assign orders to any employee they work with.
Couriers can see the orders assigned to them and orders that are unassigned at all. They can also take on the unassigned orders and change the status of orders that are assigned on them.
