External Accounting Error - Cannot Post to Xero

Error - ‘Cannot Post to Xero: Xero API Error: Payments can only be made against Authorised Documents'

This error will appear when there is something stopping the receipt from posting to Xero. This would normally be if a receipt was manually created in Xero against the relevant invoice.

This would cause the invoice to be ‘paid’ already in Xero and so the receipt from Wise Owl cannot post across.

To fix this, go into Xero and find the invoice that the receipt is for. Check for receipts that were created manually in Xero (hint - check the history for if it came by Wise Owl API or if it was created by a user).

Remove the receipt from Xero and then resolve the error against the receipt in Wise Owl.

The receipt will then post and you can match this in your bank feeds.
