Map inflows and due dates
A monthly budget can look balanced while one week still has more bills due than cash available.
Use weekly spending limits carefully
A weekly number is only useful if it still leaves enough for bills that occur later in the month.
Track irregular weeks
Travel, holidays, school events and seasonal costs can make one week unlike another.
Reconcile with the monthly plan
Weekly cash flow and monthly budgeting should describe the same money, not create two separate sets of assumptions.
