We just started using the POS software here at our restaurant about 3 months ago and we wow, it is freaking impressive, we have 9,532 unique customers and we have the order history of every single one of them! We previously had no way to do this. They told me they will build an automatic profile for every customer who visits the restaurant automatically but I was skeptic until i saw a live demo! They actually used my credit card and sold me a drink for $2.99 and yes my profile was created.
I look forward to deploying this to all of our sites and to start using their marketing automation in order to get our existing customers to spend more money while welcoming new users and etc. I highly recommend it for any fellow restaurant owner.
