Kick your customer service up a notch with automatic e-mail order confirmation for your phone and delivery orders! Your cashiers will be prompted to ask the customer for their e-mail at the time of the order (just the first timethen it's saved). Then the system will automatically send a copy of the receipt after the order is complete.
You can also have the system send a confirmation at the time the order is assigned to the driver, letting your customers know the order is on its way. What's more, all this helps to collect e-mail addresses which you can use for future marketing promotions!
