You can view the details of your client's order by heading to the main menu and clicking Selling » Orders.
When you first visit the order screen you will see a list of your currently open ("new" or "ordered") orders. To view previously fulfilled or canceled orders, or to simply filter the open orders by name or order number, click the box next to "Showing Data For:" and change the filter/search details. Once you've selected the filters of your choice, click Apply to view the filtered results.
