We recommend using Revel Systems. That said, most classic fast food restaurants like McDonald’s or Burger King use older POS systems they have had partnerships with for a long time. Franchise-level POS systems are often not the best for small businesses. That’s why we brought up Revel Systems. It’s a POS system that caters to small businesses and has drive-thru management tools, so you can make that perfect fast food restaurant without spending a fortune on POS.
