It is normal that the total profit and loss do not match the profit. Profit and loss should be gross profit. Generally speaking, it depends on the business situation, either the daily turnover or the daily gross profit. The daily net profit is ugly, because it is difficult to calculate the daily rent, water and electricity by hand, which is not convenient to calculate. Generally, month, quarter and year are used as the calculation cycle of net profit. So your profit and loss don't match your net profit.
