How to change field label in checkout

We need to implement a payment plan and propose to use the coupon feature to calculate deferred payment, but instead of showing "Discount" in checkout page and invoice we want to show "Deferred" how can this be achieved?

Hello Tobin,

We will get this checked and look for a workaround. We will get back to you ASAP.

Thanks for your patience in advance.
