A start date should be set only when migrating an ongoing business to Manager. The purpose of a start date is to allow closing balances from the previous accounting system to be entered as starting balances in Manager. When Manager is used from the beginning of business activities, a start date is not necessary.
Go to the Settings tab and click Starting Balances:
Click on Set Date:
Enter the desired
Start Date and click Update:
Transactions dated prior to the start date will be ignored by Manager, except those used to establish starting balances.
