  1. Hover over the Gear icon and click Settings
  2. Click "Chart of Accounts" from the Accounting section
  3. Click Merge Duplicates
    • This will displays the chart of accounts table with a selector column
  4. Check the checkboxes for the two accounts that need to be merged
    • Note: Only two duplicates can be merged at a time. Multiple records require multiple merge steps.
  5. After selecting the accounts, a comparison table is displayed with the record information to choose which data (name, address, etc) to retain.
  6. Clicking merge will merge all payment information into one account preserving the selected information

After completing the merge, run the sync and the error should be resolved. If not, please contact Customer Support.

  1. In QuickBooks, place an asterisk (*) in the account name
  2. Initiate a sync to pull the account in to
