hm maybe just do different sublocations for each UPS account?

thats a great idea. Currently wwe dont haev sublocations setup. So i could create a custumizations to auto pick the location based on the shipping method selected WHICH WILL BASICALLY DETERMINE THE UPS ACCOUNT. one quick ques on that though is if i create 2 sub locations under each location will that create a big mess in terms of inventory tracking at sub locations and the whole 9 yards? or can i have sub locations as sort of dummy/phantom locations?

Yea I think it could get messy pretty easily. One method of simplification might be to have things sit at the parent location then kick off an Inventory Transfer to whichever child location is designated at the time of shipping. Doesn't seem very elegant tho. There might be a better way
