"I sincerally hope that your team can show a way to do this. I have trying for weeks and i have not be able to find any information about how to do it. I pay my team depending of my net earning and every week is a headache do it manual."

Another thought:

If you're on cash basis for tax purposes, you can use your cash basis P&L for tax purposes and your accrual basis P&L for internal use.  If you date Invoice A in Feb. and Invoice B in Jan., QB will show $5K in Jan. income and $2K in Feb. income on accrual basis.
