2 of our independent contractors are being hired as employees on 01/04/2021 One was accepted by QB Payroll, the other gave me an ERROR - The name supplied exists

Hello, @accounting453.

I want to make you're able to record the vendor's name in QuickBooks Online without any error. 

Let's change the  Display name format or adding symbols in recording the vendor. This way, you can get rid of the error.

 Let me guide you how: 

1. Go to the Expenses, then choose Vendors.
2. Locate and hit the vendor name, then click Edit. 
3. Under the Display name as a drop-down arrow, choose the other one. 
4. Tap Save. 

For more information, visit this article: Error: The name supplied already exists. Another customer, vendor, or employee is already using this....
