Using a booking system

A friend of mine is running a hotel. He's shown me the importance of having a hotel booking system when you're running a hotel. That system is the software that keeps everything in place and in order. You can see information about you customers and what room they're in. All that stuff can be kind of hard to memorze in your head. I think no one can, well, almost no one. But the easier way is to use this booking software. I know I'm gonna use it when I start my hotel!
