This application allows the shop owner to track the whereabouts of the courier who is delivering the package to the customer's address. This system is expected to minimize the possibility of parcels not arriving at their destination due to naughty couriers and features to store customer data whose address coordinates are automatically updated when the courier completes the customer's order. For prospective buyers who place fictitious orders (PHP), this system will record the behavior and then share it with other shop owners as a warning of the existence of a fictitious order that the person is doing. Store owners can review transaction history and see the location of their sales distribution. In the future, various features will still be added according to the needs of shop owners and couriers in the field.
