We need to get our client's Magento store to handle Drop-ShipShipper Origin Zipcodes so that each Supplier / Drop-shipper has a designated unique zipcode. Magento only offers one origin zipcode currently. Ideally we would like a contractor who has done this before.
This is the scenario we need help with. We handle clients who use a few large drop-shippers with 4-5 distribution points each around the USA. We would like to be able to be extremely accurate when we charge for shipping and have the UPS shipping calculator give proper shipping fees for orders taking into account the closest distribution point (ship from address) to the buyer (ship to address).
So, I am assuming the key variables to be used in shipping fee calculations are A) Which drop-shippers is associated with which products and B) The Closet Distribution Pt (zipcode) for that drop-shipper then C) The ship to zipcode of buyer.
