Wait until the end of the period! Close Period is for reconciling after all bills are paid and spending has occurred. Mid-period, your bank balance will be higher than Living Money because projected expenses haven't happened yet.
Reconcile this period by entering your actual bank balance at the end of the period.
Projected Living Money: $792.00
If your actual balance differs, a reconciliation adjustment will be created.
After closing, click Sync All on the Runway page to cascade the corrected balance to future periods.
