If your QuickBooks Online upload/download is failing:
Click the Sync icon (Two horizontal arrows pointing in opposite directions) in the top right corner to force the manual sync.
Open Synchronization Log: click the Bell icon in the top right corner and select View all Messages.
In the appeared Synchronization Log page select either 'show only errors and warnings' or 'show all messages' and find the failed transaction/entity and the specific error message. In most cases the error message is clear and it can be fixed manually by updating some information in HandiFox entity.
- If the error message is unclear, contact support@handifox.com with the error message and detailed description of the problem.
Note: Please do not try to disconnect and then connect HandiFox to QuickBooks Online to resolve the synchronization issues. Disconnecting and then connecting to QuickBooks Online will archive all HandiFox specific info from your account (barcodes, sales orders, serial/lot numbers).
