We highly recommend resolving syncs with a Failed/Canceled status to make sure all your transactions are recorded in your books. When you encounter a sync with a Failed/Canceled status, always click the ‘Explain’ link to get more information.
In some cases, you might see the following error message when you scroll down to the Sync log section:
Line.SalesItemLineDetail.ItemRef: Invalid Reference Id : Line.SalesItemLineDetail.ItemRef.
This error is related to a temporary issue on the QuickBooks Online side. Synder has automations in place that periodically resync these failed transactions, so they should be eventually resolved.
Alternatively, you can simply click the ‘Sync again’ button to push it to your books.
Reach out to Synder Team via online support chat, phone, or email with any questions you have – we are always happy to help you!
