Auto Gratuity and Service Fees are additional charges to your customers' bill. Each option will have different reports found in the management console.
Auto Gratuity is a mandatory charge relating to tip to your customers' bill. This is useful when your business automatically charges a mandatory tip percentage, for parties of 6 or more. Enable this feature in Settings > Enable Auto Gratuity in the management console.
Service Fees allow either a percentage charge or flat fee to be added to an order. A service fee can be added manually or automatically applied, based on dining type, guest count, payment type, or time slot. For example, you can setup an service fee to automatic apply for delivery orders.
