Open a client with an existing Payment Schedule.

From the Billing tab, click Lump Sum Payment. The Lump Sum Payment window displays.

Select the Payment Method.

Select a Date.

Tick Brought Forward if the Next Scheduled Date should be changed and select the date it for the next payment due.

Note: If making a lump sum payment causes a partial payment, the partial payment is scheduled for the date of the most current payment due. The following payment due will have the new Brought Forward date.

Enter the Amount.

Click OK.

The Payment Schedule now has a new payment due date.
