Your customer has asked you to do direct shipments to *their* customers and to make it appear as if it is coming from them, not you - so this means their logos, their customer ID's and some other key information that gets duplicated.
You can set up a different sales order type, add the new or duplicate fields as needed to the sales order object, create a custom report with their logos and make sure the right information gets captured.
Is anyone doing this - have any tips or tricks to share?
