Moulk delivery app is an application for IOS and Android, developed with JS, and React Native. It is intended for the use of couriers, who work for Moulk store. The application is intended for couriers of the Moulk system, the courier has a separate section in the Moulk system, and when an order is received in the Moulk system, after being processed by the operator, it is transferred(forwarded) to the appropriate courier. The warehouseman then gathers and sorts the products needed for the orders, once completed, the system indicates that they are ready for delivery and waiting for the courier. The courier, observing that the orders are ready for delivery, picks up the goods from the warehouse, confirms the received orders by the system, and takes them to the address indicated. It is possible to change the status of orders (accepted, rejected, or requested to change). All information about the delivery, rejection, or refund of orders is notified through the application. When the status changes, other members get notified about the status update. Real-time delivery tracking is also available, so operators and warehousemen can track the order and know where it is. The application allows the courier to work more efficiently and systematically. Courier can classify orders at his discretion. The accumulated amount from orders is automatically calculated by the system and then reported on a daily or monthly basis.
