Vendors showed up that I did not add

Welcome to the Community space, 

I am here to provide insights about the vendors that showed in your vendor list that you didn't add in QuickBooks Online (QBO).

 When downloading bank data, enabling the Remember category selection and Show suggested rules options can cause vendors from your bank to sync with QuickBooks. To disable this feature, follow these steps:

1. 1. Click Banking on the left side menu.
   2. Choose Banking.
   3. Tick the Gear icon on the right side menu.
   4. Uncheck Remember category selection and Show suggested rules from the Transaction details section.

Also, your invited user may add a new vendor to your QBO. I suggest reviewing your Audit log to check if any changes have been made to your vendor list.

Moreover, I'm adding this helpful article as your reference in managing your expenses in QBO: Enter and manage expenses in QuickBooks Online.

Return to this post if you have more questions about your vendor list in QBO. The Community is always here to help.
