After a customer has placed an order, you will receive an email notification about it. If you are using the mobile app, you will get a notification on your mobile phone. To find the details of the order, you can log into your admin site, navigate to the Cogwheel Icon and then select E-Commerce.
In the E-Commerce area, there is a tab called Orders. Under this tab, you will find the order details, such as order date, customer name, order amount and there is a checkbox called Delivered. This is for your order management and you can check this box after the order has been delivered.
The delivery address and the order receipt can be found after you clicked on the order.
