FAQ

Quick answers

Short answers for the questions that usually come up first.

Why include an installment fee?

Because some payment plans carry a financing or administrative fee that changes the real collected total.

Can I use this for zero-fee installments?

Yes. Leave the installment fee at zero and the total is simply split evenly across the installment count.
