QuickBooks Online sync error: Another customer, vendor, employee, or donor is already using this name in QBO. Please use a different name or ensure that there are no duplicates in Bill.com
Why the sync error occurs
This error occurs when a contact (customer, vendor, or employee) is trying to sync to Quickbooks Online from Key CashFlow, but a contact of the same name already exists in Quickbooks Online. All contacts must have unique names in Quickbooks Online, regardless of contact type.
How to fix the sync error
Edit the name of the customer, vendor, or employee in Key CashFlow so it is different than the existing contacts in Quickbooks Online, and sync again.
Note: We pay vendors using the Pay To field, so you can edit the vendor name field and it won't impact the payments.
If you have duplicate records that you need to merge, please contact Customer Support. We can help you merge the duplicates properly, and avoid additional sync errors.
