What does Westsoft's AR account mean?

AR account: it is financial accounts receivable.

This is easy to understand. For example, Customer A is an employee of China Bank. He stayed in the hotel for one day and spent a total of 888 yuan when he checked out. Guest a doesn't pay for it himself right away, but asks to call it into the corresponding account of their company! The premise is that guest A will show the relevant documents and signature handwriting, and the hotel will confirm it. That's probably what it means. You got it?
