Centralized vs Decentralized Systems

We currently have a completely decentralized distribution network and have been looking at the idea of centralizing. Currently our distribution centers have local customers that they bill as well as corporate customers being billed by the headquarters. It is of my opinion that a distributed system with a central data warehouse is the way to go. This would allow corporate customer information to be send down to the distribution centers data subset and allow the distribution centers information to be consolidated at the corporate headquarters for sales reporting purposes.
Does anyone have an opinion, comment, or concern to share on this topic?
