You may want to Hold an invoice. This is where all future payments are paused until you activate the invoice again. When the invoice is reactivated it will automatically alter the Payment Schedule. 

To hold payments, locate the Payment Schedule and then click on the Hold icon.

The status on the Payment Schedule will change from Active to Hold.

Once a payment schedule is on Hold you can return its status to Active. To action this, click on the Release Payment Schedule icon. This will also change the Payment Schedule to reflect the schedules previous status i.e., on Hold.
