Hello,
As some others have said as well, i have both customers and suppliers, there should be an option to tick where a business is both. As most of the information is the same, there could just be an extra tab or two to incorporate the differences and away you go. Alternatively it would be good use the Spend Money to create an EFT payment file to be processed thru the ABA upload to the bank.
Cheers
