sunday transforms the way full-service restaurants operate by making payments invisible and loyalty effortless. Guests scan a QR code, pay in seconds, leave bigger tips, and automatically join your loyalty program—no apps, no friction. Operators benefit from faster table turns, happier staff, and smarter data. Already trusted by leading US groups like Lettuce Entertain You and Parched Hospitality, sunday is built by restaurateurs, for restaurateurs. Whether you’re scaling a group or streamlining a flagship, sunday helps you serve more guests, more profitably.
