How do you process my order information?
Are orders processed automatically or do they have to be done manually? This is a strong indication of a potential fulfillment provider's technology capabilities. Fulfillment providers who specialize in eCommerce order fulfillment and built themselves from the ground up with online capability in mind will almost certainly have this feature, while traditional warehouse companies won't. Good technology is one of the most important parts of fulfillment, make sure to ask your potential fulfillment partner how they process order information.
