If you need to set up a new sender address (induction point for FedEx account) Techship has the checkbox at the Client level accounts:
For FedEx account: "override sender address", can be used also as an induction point
For UPS account: "override shipper address", cannot be used as an induction point
Account for UPS is always linked to some specific territory.
1. Ship from CA with CA account and bill any other third party registered in any country
2. Ship from US with US account and bill any other third party registered in any country
3. Ship from CA with US account regardless of location of third party billing account
4. Ship from US with CA account regardless of location of third party billing account
Adding new carrier with a new address is the same as override ship from on client level. Also, adding new carrier will be the case manifest discrepancy, so since the closing of one manifest will close both of the carriers.
Also, please see the following Techship option - Checkbox "Enable TPL Billing Override (for DHL, FedEx, Loomis, Purolator, Sameday)"
