Why the Sync Error occurs
This error occurs when a bill, invoice, or payment is attempting to sync from Bill.com to QuickBooks Online (QBO), but the accounting period is closed in QBO.
How to Fix the Sync Error
There are three options to fix this error:
- Change the date of the transaction on the bill or invoice in Bill.com to a date in an open period in QBO
- If the transaction is a payment, you will not be able to edit the payment date in Bill.com; proceed to the next 2 solution options
- Record the transaction/update in QBO manually and contact Customer Support to clear the error
- Open the books in QBO to allow the transaction to sync, but this option is not recommended as we cannot control if other transactions in Bill.com may sync in to the newly opened period
