Welcome to the Community. It would be my pleasure to help provide some information about paying vendors in QuickBooks Desktop.
For you to pay the vendors using the Direct Deposit feature, you may need to sign up for a Payroll and Direct Deposit service. Using Online Bill Pay only allows you to pay bills through Online Bank Payment.
For additional insight into the direct deposit for vendors, and how you can sign up for the services, I'm adding the articles that I recommend:
- Manage direct deposit for independent contractors in QuickBooks Desktop Payroll.
In case you want to know more about the Bill Pay feature as well, please check this out:
Thanks for coming to the Community. If ever you have additional questions regarding paying the vendors, I'll keep an eye out for your response.
