Why the sync error occurs
This error occurs when a payment on an invoice is trying to sync from Bill.com to QuickBooks Online, but the related invoice or account has been deleted in QuickBooks Online, or the sync connection has been broken.
How to fix the sync error
You'll need to verify that the account on the payment, and the related invoice are both active in QuickBooks Online.
In QuickBooks Online:
- Hover over Sales and select Invoices
- Locate the invoice related to the payment with the error and make sure it's active
- Hover over Accounting and select Chart of Accounts
- Locate the account related to the payment with the error and make sure it's active
Once you've verified both the account and invoice are active, sync again.
If the error persists, or if you need to resync the invoice or account to QuickBooks Online because they are missing, please contact Customer Support.
