Fumbling over the phone, bad reception, long waiting for food and the pressure of a long line can result in your customers spending less overall.
While more quick-service and pizzeria customers order in person or over the phone right now, that may not be the case for much longer. Time being, restaurants have experienced a great success with online food ordering systems. So that the customer can take their time to clarify their order, and be precise.
Restaurants opting to use in-house online ordering software through their point of sale system - like eat24/grubhub/talabad - see many advantages compared to those exclusively using a third-party service. These perks include higher profits, insights on individual customers, a customizable user experience, and more.
So it's better to adopt an online food ordering system in your restaurant - especially one that's integrated with your point of sale to improve efficiency.
