We have enhanced our system to allow you to add bill 3rd party FedEx / UPS accounts to your shipping profile. Sometimes a marketplace will require you to ship using accounts provided by them as "bill 3rd party" account. Now Teapplix allows you to preset such account into Teapplix and anytime you print using such profile, it will be automatically bill 3rd party.
Details of the setting is here:

Other Profile Enhancements
If you use our Chinapost ePacket Service, you an also link multiple ePacket accounts based on shipping profiles.
