How do you offer a payment option of a big ticket item?

Hi there,
I have a product that is a one-time payment of $999, which I can easily code with the Stripe API - “Charge the current customer user.”

I want to offer a payment plan, for example, three equal monthly payments of $333. I’ve set up a Plan in Stripe, but there doesn’t seem to have an option to provide three equal payments.

It seems that I would have to take account of the billing and charge the customer equal payments. Or would I have to set up an Invoice through Stripe?

Does anyone have any experience or insight on how to implement this?
