Archived Contact Records in Xero

"The contact with the specified contact details has been archived. The contact must be un-archived before creating new invoices or credit notes"

The above error occurs on posting an invoice to Xero, where the contact record in Xero, the invoice is being posted to, has either been archived or merged with another contact record. Typically, this occurs where you are using a single generic customer record in Xero to post invoices against.

The solution is to either unarchive the Xero contact record in Xero or create a new contact record in Xero and point Tradebox at that new Contact. To do this, go into the Channel Record in Tradebox, click on the XERO tab and then select the Contacts tab. Select the new Xero contact from the "Default Contact" drop down list and then choose Save.
