When you are connected to your vendor's Bill.com account for ePayments, your vendor has the option to mark their bill as paid in their account, but this does not create a live payment.
Your vendor may choose to do this if you paid them via credit card, check, or any other method outside of Bill.com.
To make sure you don't also send a live payment through Bill.com and overpay the bill, when your connected vendor marks their bill as paid in their account, we will also mark the bill as paid in your account, and let you know we have done so with a banner on the payment record and a tool tip on the Payments Out page.
If you believe your vendor marked the bill as paid by mistake, we suggest reaching out to them to confirm before voiding the payment.
