From room upgrades at check-in to choosing upsells like late check-out during the stay, anything can be incorporated into the app. Add your food & beverage menu, spa treatments, room service, and items from the gift shop.
Do you have an extended stay property? Charge for additional housekeeping in between regularly scheduled cleanings.
You can even add off-site food & beverage and other services, and the property receives a percentage of those sales.
