I understand the importance of resolving this issue, Mark.

I know you've contacted Melio's customer service about the bill payment your vendors never received. The best way to investigate and resolve this is to contact Melio Customer Support again. Their representative can track those payments and conduct additional research to determine the root cause.

You can get their phone number by following this link and going to the Contact page below the App information: Melio.

If you need help managing your vendors and transactions, you can always refer to our Income and Expenses article. This guide contains resources to help you manage your expenses in QBO.

I'll be around if you have any further questions. Have a great day.
