Statement of cash flows is time period sensitive. For the included dates if there are entered, unpaid bills they MUST be included in the A/P adjustment to adjust net cash provided by operations downward. If you do not want A/P in the report then :
1. DO not enter any vendor bills but instead wait and just enter checks - then the numbers will appear in top line of Net Income.
2. Wait to run report AFTER bills are paid
Do not consider making your own adjustment to the numbers. An unpaid bill is an unpaid bill. Period.
