We need the ability to manipulate rates or show no rates for each user. Both UPS and FedEx have this feature in ups.com CampusShip and fedex.com ShipAdmin. We have many users and / or third party vendors that use our accounts and we charge them additionally or public rates when using our UPS/FedEx account. We need to be able add handling charges as a percentage or fixed amounts on top of base shipping charges. For some users, weâd like to hide the rates completely. This is common practice in shipping industry and weâre surprised you donât have that configuration option available.
