This error message indicates the account has been closed to editing on the Quickbooks side. This is often done by accountants after they have gone over and reconciled a period so that no further changes can be made to that period. To resolve this, the User should speak to the person that did this in order to clarify why.


1. Go to the Home tab in Quickbooks
2. Click on the Gear icon in the top right and select Company Settings
3. Click the Advanced tab
4. In the Accounting Section, there is an item that says "Close the Books" This date needs to be changed in order for Syngency to sync any items before that date. The Syngency user will want to consult the accountant or whomever set the date.
