How do I fix the "The name _____ of the list element is already in use" sync error?

This error is fairly common and easy to fix. Take these steps to resolve it.

If you receive the following synchronization error is in the synchronization log file:

Error Customer SubmitCustomerBatch: error while creating customer Mike Smith {640437EF-BB94-42AC-A59F-92EA45881892}: The name “Mike Smith” of the list element is already in use.

This message is received due to creating a customer in Acctivate with a name that already exists in QuickBooks as an existing customer, vendor, employee or other name.

You can resolve this be following the steps below:

  1. Locate the duplicate name in QuickBooks in the following lists:
    1. Customer Center
    2. Vendor Center
    3. Employee Center
    4. Other Name List
  2. Rename the duplicate name in QuickBooks
  3. If Mike Smith already exists as a vendor, change the existing vendor to Mike Smith (Vendor). This will not affect the name that prints on checks.
  4. Run another Synchronization

QuickBooks treats “Mike Smith” and “Smith, Mike”as duplicates. Please be sure there are no variations of the same name.
