Whether a tenant's auto-pay adjusts to the actual balance on their lease depends on how the auto-pay was set up.
Auto-Pay Options
Entire Balance — The auto-pay charges the full current balance on the lease each cycle, regardless of amount changes
Set a Maximum Amount — The auto-pay charges up to the set maximum; if the balance is lower, it charges the actual balance
Fixed Amount — The auto-pay always charges the same fixed amount, regardless of what the actual balance is
If a tenant's auto-pay is not adjusting as expected, have them check which option they selected and update it if needed.
