I need to show that a vendor invoice has been paid by electronic banking. How do I set up the vendor with EFT functions?

Here is a link to the ShowMeHow video on our website to Set up EFT in Adagio Payables. There is another video to Use EFT in Adagio Payables.

Hope these help.

I think you're looking for something different. If you have paid a vendor externally, record a manual cheque in a check batch to the vendor and turn off the option to print a check for the payment. You;ll need to make up a check number for the payment. Often the confirmation number makes a good one.
