Is there any easy way to merge multiple duplicate vendors?

Thanks for reaching back out to the Community, @DonnaSanchez. I'm here to help you merge the duplicated vendors.

At the moment, merging duplicate vendors would need to be done individually.

Here's how:

1. Select Expenses, then Vendors.
2. Choose the name of one of the duplicate vendors, then select Edit.
3. Change the Title, First name, Middle name, Last name, and Suffix to make it identical to the vendor you're merging with. Ensure that the Display Name is also the same.
4. Click Save, then Yes to confirm that you'd like to merge the two vendors.
5. Repeat this process for the remaining duplicated vendors.

I'm only a reply away should you have any other QuickBooks questions. Have a great day!

is there a way to do so in one go for many vendors without having to open every one?

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!
