Hi there, @bmillener-rotags.

Thanks for reaching out. I hope you're having a wonderful day so far. 

I'm happy to lend a hand with canceling your vendor payment. I'm including some steps below to walk you through the process. 

1. Sign in to your QuickBooks Online company file.
2. Select Expenses, then Bills.
3. Click on Show Bill Pay payments.
4. Choose the scheduled bill payment from the list, then tap on View details.
5. Select Cancel this payment.

For additional details about this process, check out Learn about QuickBooks Bill Pay. 

I'm also including our guide to set up payments for vendors, in case you may need it in the future: Pay a vendor. 

Please don't hesitate to let me know if there is anything else I can assist you with. Take care!
