How do I merge a contractor.

It's good to know you've followed the steps provided by my colleagues above, @mconnex. I'm here to ensure you can merge a contractor in QuickBooks Online (QBO).

Upon checking our database, we have an ongoing investigation of the error "Another Vendor is already using this name. Please use a different name" when merging a vendor. This means that other users are experiencing the same issue on their end. Please know that the product engineering team is already aware and working on finding a permanent fix as soon as possible. 

For now, I suggest contacting our Phone Support team so you'll be added to the list of affected users. This way, you'll receive an email once there's a resolution. Here's how you can contact them:

1. Go to the Help icon in the top right-hand corner.
2. Select Search, then press the Contact Us button.
3. Enter your question in the box and hit Continue.
4. Please choose the best way you'll want to reach out to us.

Be sure to review their support hours so you'll know when agents are available.

Moreover, you can run several reports to view vendor lists. You can also customize it to focus on the information that matters most to you.

If there's anything else that I can help you with managing vendors in QuickBooks, never hesitate to leave a reply. The Community team is always around to help.
