If transactions have been processed as Authorise-only, they will be settled only when the order has been manually invoiced. 

Submitting a Manual Invoice

To manually invoice an order, you need to:

  1. Locate and open the order
  2. Select  Invoice from the top right

On the New Invoice page, ensure that the Capture Online option is selected from the Amount dropdown menu, then click the Submit Invoice button.

This will then initiate a FULFIL transaction to MasterCard Payment Gateway Services.
