Hello there, @atrbsg.

Let me share some information about merging multiple vendors in one go.

QuickBooks Online (QBO) only allows you to merge vendors in pairs to avoid errors. I understand that merging them at once will save you time. However, this option is currently unavailable in QBO.

For now, I encourage submitting feedback directly to our product engineers. They may look into this suggestion and consider adding the option in the future update. To submit feedback, you can go to the Gear icon and select Feedback. Then, enter your suggestion and click Submit.

You might also want to view the status of your vendor's transactions. You can go to the Expenses menu and select Vendor.

We're always here to listen if you have concerns regarding other features. You're welcome to post again or leave a reply below, @atrbsg. Wishing you all the best!
