Error When Syncing > Failed to validate signature

Applies to: ConnectWise Manage, Xero


How can this happen?

If you receive the above error it's because of an invalid character in either the Vendor Invoice or Purchase Order. 

Common examples include

  1. There is an # in the Vendor Invoice Number
  2. There are leading or trailing spaces in the PO Number


  1. Open the Purchase Order that has failed to batch, and edit the vendor invoice number so that the # or any other invalid characters are not present.

  2. Open the Purchase Order and remove any leading or trailing spaces in the PO Number.


Partners using the "Alternate Vendor Invoice Date Source" will need to ensure that the invoice is updated at the correct location, based on the setting selected.
