The first thing depends on what kind of hotel you are. Hotels with more than four stars are relatively rich in funds, all of which are soft in the middle and soft in the west. Of course, the cost in this respect is quite high. My hotel has more than 100 rooms, using the software of Golden Swan, which has quite complete functions, including catering and warehouse. It's very simple to use. I am a newly-opened hotel, and most of them are novices. When I bought the software, it took the staff only one afternoon to operate the software. Basically no problem. I chose Golden Swan at the beginning, mainly because I took a fancy to their anti-leak function, controlled personnel authority, printed business cards for door locks, cleared card lists and made financial statements very clear. You can go to Golden Swan to learn about it. ~~
