Customers are not able to come to your stores. Your hours are changing. You are interacting with your customers almost exclusively over the phone and internet.
Knowing how important it is for retailers to keep in touch with their customers – and to not miss a phone message – Numa is giving its app away for free for 60 days to assist businesses during COVID-19. They can use the app to give automatic messages to callers (easily changed from anywhere), manage all phone and text communication from outside the store, ask customers to opt-in for mass updates for re-opening, text others for orders, coordinate curbside, and a lot more.
