Verona POS helps you to build your data customer correctly. You can use that data for marketing purposes creating email marketing, loyalty programs, rewards and promos, post service, etc.
We know it may seem strange to talk about post-service in a restaurant, but that is possible if you manage your loyalty program correctly. Make sure each customer has shared their contact details and date of birth with you or your team, with this information on your POS system you can create marketing strategies that allow you to retain customers and they will recommend you more and more. To do it you just need a design person who reviews the historical visits and send them emails of thanks for their visit including future promos and special discounts.
Remember that people need to feel like they received good value for their money.
