Enforce Payment Upfront

Hi all,

With most of our customers we require payment upfront. Is there any way to enforce this in the system? Ideally we would set it as the company credit limit so that it’s used by default with more lenient terms being set on a per customer basis. Unfortunately setting a credit limit of zero simply disables credit limits instead of requiring an upfront payment, and we would like to do it more cleanly than setting an arbitrary limit of $0.01.
