How can I set up payment plans on Weebly Business?

[JacintaVW]

Hi, I am in need of offering customers different payment plans for a program I'm offering. I've looked into Square, and Paypal but nothing seems to allow, for a limited time, this option (Square allows but I don't see where it allows me to put an end date). Can you help? Thanks!

Square offers Afterpay however, the option for you to set payment terms does not appear to be a feature but, you do get paid the full amount upfront.
