What do I do with the part of the invoice or bill that I usually mail back to the Payee with my payment? Doesnt the vendor need that to process my payment?
No. The vendor does not need the payment stub that accompanies your bill. As a precautionary measure you may wish to keep the payment stub until payment of your bill shows up on your account on SMART Web or until you receive your statement that displays the transaction. You may also wish to keep the stub and bill for reference purposes, however, this is not required and once the bill has been paid you may discard the payment stub.
