If you are wanting to use Despatch Bay as a carrier, you may also want to use Parcelforce Express 48 as a service. This is possible to do without having to set up Parcelforce as a separate carrier. It is titled "Economy (Parcelfore)" under the services tab.
Navigate to wherever it is you would like to insert a Carrier and a Service. Select "Despatch Bay" as the carrier, then under service locate and select "Economy (Parcelforce)" as shown below.
Note There are multiple Economy/Parcelforce services, if you are wanting to use Express 48, use the exact one shown above.
