UPSAE

Hello all,

I am a UPS Account Manager. One of my accounts, a large fullfillment house uses MOM. They are telling me that they need a unique UPS shipper number for each of their customers, because MOM gives an error when they attempt to use their one and only UPS shipper numbers for multiple companies. I believe they are trying to seperate each of their customers, possibly for accounting purposes, by using a uniqe UPS shipper number for each customer. Has anyone heard of this situation? How would you use one UPS shipper number and keep the clients of the fullfillment house seperate? I did open up a new UPS shipper number for them as a test and it worked. However, they are now wanting to add 30 additional UPS shipper numbers. Any ideas?
