Problem statement

Every time you place an order at a store, have you ever wondered about the process behind the final delivery? Your order may arrive very quickly, sometimes before the estimated delivery date. How does the business handle all orders and payments? How can they efficiently meet the needs of so many customers, from orders to doorstep delivery? This process is called order management, and it basically tracks customer orders and manages the steps taken to fulfill them.

Tracking orders may be relatively easy at the start. The best thing at the time was taking orders. But as the business grows, as sales increase, channels increase, products are added to the inventory, and the customer base grows, potential roadblocks can arise.

Providing customers with accurate shipping information and tracking updates is crucial to customer retention. It is a powerful way to improve the customer’s shopping experience.
