Order Total Must Not Be Negative - Webgility Desktop
Reason:
This happens when the order total is negative. The most common reason is the refund is not set up properly in Webgility.
Troubleshooting:
1). In Webgility navigate to Integrations> Stores> Settings> Download Settings, Download Options. Enable “Get refund and record in" then select a discount or non-inventory type item from Quickbooks then Save & Continue.
2). Now go to the Order and redownload it. After you re-download the order try to post it again. It should post successfully.
