Ke Ruyun's cashier software is relatively cheap. If calculated on a monthly basis, the mobile version only needs 20 yuan, and the PC version is divided into three levels from basic to flagship, namely 200/500/800 yuan. Seeing that the price of lobbyists downstairs is more expensive than that of some peers, I think you get what you pay for! Different prices can enjoy different functions. Some relatives who do catering are using their products, and personally feel good.
