Customer information need be typed in only once. An 'Add Customer' button produces a pop-up, easy to fill in customer form. If customer information changes an 'Edit' button pops up the customer information for changing. Once a customer has been entered he can be selected from a drop down list and all of his information appears on the screen. Since they have many repeat customers this saves a tremendous amount of time. Calculations are automatic--another big time saver.
When a past order needs to be looked up, it can be found in a few seconds by simply typing the reference number.
