If you're referring to Installment Plan button, the grand total can't be changed to exceed more than what is set up in the plan originally.
| Installment Plan | Up to four interest-free fixed payments | Signs buyers up for installment plans that collect the first installment on checkout, with up to three additional installments or defers the first installment, with up to four future installment payments. The Installment Plan button also enables buyers to pay the full amount up front so you do not need an additional Buy Now button on your web page. All payments must be collected within one year of checkout. |
You can allow a customer to:
- pay in full
- pay equal payments at regular intervals
- pay a variable payment at irregular intervals
Installment Plans can be managed on the Recurring Payments Dashboard:

Installment plan details page
Displays the shipping address, an Installment details list, and the billing details for the selected installment plan. This page allows you to:
- Cancel the installment plan.
- Suspend the installment plan.
- Reactivate a suspended installment plan.
- View the installment plan's history.
- Modify installment plan details, except for the payment amount and the billing cycle, which were agreed upon with the customer when the plan was initiated.
A new installment plan will have to be agreed upon if they want to pay more or you want to charge more.
Kudos & Solved are greatly appreciated. 🙂
