One of the strengths of CheckBook Tracker is it's ability to store a
list of upcoming withdrawals and project them in the balance forecast
under "Cash Flow".
From the "Bills" tab, you can configure new scheduled withdrawals such
as utilities, groceries, mortgage, etc.
Choose "New Withdrawal".
Enter a start date, a repeating schedule (such as weekly or monthly)
and details about the transaction to be entered.
These transactions will show in the CashFlow graph, projecting how much
(or little) money you will have over time.
