One of the best ways you can increase sales is to review each customer's spending history each time they make a purchase.
Why? Because you never want to undersell a customer. A quick review of their spending history will make sure you don't.
For example, let's say you see that you are dealing with a customer who spends $85 on average. You don't want to let them spend any less! DO NOT suggest that they take advantage of your current $19.95 special. This customer is comfortable in the $85 range and that is where you want to keep them.
The FloristWare POS system shows you the spending history for a customer each time they make a sale. It appears right after you have confirmed their contact information.
