Monthly close Function

There are two accounting equations
Static equations: Assets = Liabilities + owner equity
Dynamic equality: profit = income-cost
The two can be combined into one
Assets = Liabilities + owner benefits + income-cost
Foreign software mostly adopts the TABLE statement method, that is to say, when the report is generated, the current year's profit is calculated dynamically based on the income and cost, and no creden are generated. Domestic software adopts the statement, generate the following two creden:
1. carry-over income
DR: various sales revenue
Cr: current year's profit
Sales return
2. Carry-over fees
DR: current year's profit
Cr: sales cost
Business Management, financial periods, fees
Income tax fees, etc.
In this way, the sum of the monthly settlement income accounts is zero.
