Can users pay a deposit now and rest of payment later?

Is there a way to set up a form so that people can pay a deposit now and then come back to that form and pay the balance later?

Thanks for reaching out to us. Unfortunately, there's no option to add a partial amount or deposit to your product.  You can, always try some workaround allowing your clients to pay a certain percentage of the price through your form. You can do that by setting radio buttons for products and partial payment options, add form calculation that will calculate the partial amount, then set that price from form calculation field is passed to the payment field.
