This error occurs when the connection between Sage 50 and the SyncTool is interrupted during a sync.
To re-authorize the SyncTool with Sage 50, please follow the below steps.
Log into Sage 50 US and go to "Options" -> "Global" and under the "General" tab, choose to Reset.
Please re-export the invoice from Beanworks and run another sync. Once the SyncTool indicates it's received the file (as shown in green text below), click back into Sage 50 US and the pop up will appear again.
Choose "Remember this setting" and choose "Yes".
The sync will complete, and you should see your invoices in Sage.
If the error persists after you have followed these steps, please contact our support team at email@example.com.
