The hospitality industry has a wide range of sectors and types of business. Operational needs and processes differ vastly between each type of business and also from restaurant to restaurant - even two businesses selling the exact same menu can demand a different technology solution.
In comparison to Retail technology, Hospitality is very much focused on a business' working procedures, stock management and the overall size of the business. Dependent on the requirements of your business the overall solution could have the need to track stock levels of liquids, recipe ingredients, handle complex billing methods and also feature room billing or integrate with hotel management software.
