Vendor Preferred method of payment

Vendor Preferred method of payment

Some of our vendors prefer to get paid via ACH or Check or Paypal. How are people tracking how a vendor likes to get paid?

We are using a custom field right now to track it, but when creating a bill, that information doesn't show up on the create bill page. I've resorted to adding the data to the PDF of the bill (underneath their address). That seems to be ok, but wondering if there is a better alternative.
