We have started to pay vendors via ACH which is awesome, thanks!! We're finding that it's difficult to retrain our AP users to click the Pay By drop-down for ACH and then for checks. I'm thinking a checkbox in 4-4 or ACH tab in 7-1 that says something like "Pay with ACH Only" or "Pay Vendors ACH Only" so that they can't get a paper check if the ACH is set to a status of 3-Active would work to prevent a vendor from getting a paper check by mistake. I know there are other ways of preventing this but it might be useful for those random times when it happens.
