QuickBooks Online Sync Error: The name supplied already exists: Another product or service is already using this name. Please use a different name

Why the Sync Error occurs

This error occurs when there is a duplicate Item (product or service) in Bill.com.

Verify that the new Item created is needed in Bill.com
- If it is not needed, delete it
If the Item is needed, edit to update the name to something unique
If the Item is not a duplicate, contact Customer Service to link the Item between Bill.com and QBO
