Why the Sync Error occurs
This error occurs when a PO is attempting to sync to Bill.com from Sage Intacct, but the amount on the PO in Sage Intacct is outside of the allowed amount in Bill.com.
How to Fix the Sync Error
In Sage Intacct, edit the PO so the amount is between $0 to $99999999. We do not currently support negative PO amounts, and if the amount needs to be over $99999999, you will need to split the amount in multiple POs in order to sync them.
