Xero Sync Error: This payment may have been already recorded manually in Xero (AR Payment) – Support

Why the Sync Error occurs

This error occurs when a receivables payment cannot sync to Xero because a payment has been recorded manually in Xero.

To allow the payment to sync, delete the payment in Xero, then sync again.
If choosing not to delete the payment in Xero, select I've updated this Bill in Xero; remove this error and sync future updates
- If selecting to retain the manually recorded payment in Xero, for receivable payments that were made via Bill.com the payment account should be Money In Clearing Account
- If selecting the GL for the bank account, the Money In Clearing Account and the bank account in Xero will be out of balance
Offline payments should not be posted to the Money In Clearing Account as there would be no funds transfer to offset it.
