What happened when the turnover statistics of Wan Wei Hotel Management System were negative one day?

I haven't used your software, and I don't know which part of the turnover in your system is included.

I use the x8 hotel management system. There are two versions. One is the income and expenditure statement, which records all cash inflows and outflows. There may be a negative number in this statement, because there may be more check-out and deposit refund today, so the cash flow may be negative.

One is the consumption business table, which is all the closed consumption records and cannot be negative.
