My wish list is for a Note line on an Accounts Payable check where we users can enter such information as vendor account number, loan number, bank credit card number, Property tax id number, etc.
 
Currently, I use the last line of the remit to address, but sometimes this is not a good practice, especially when it displays the credit card number.  The window envelope for the AP check then reveals this number in its clear window.
 
How does anyone else handle this?   ???

It would be better, IMHO, if it were a field in AP-A so that it would automatically be put on every check (assuming you added it to the check RTM).
 
BTW, I agree with the concept. One of the few things I missed when we converted from Peachtree a few millenia ago.
