In the paper we investigate what impact the deployment of wireless technologies can have on a supplier who manufactures a product and customizes it according to the individual wishes of his customers and how mobile solutions affect the supplier's inventory and transportation decisions. We derive several mathematical models for a special case when the supplier's representative visits each customer to approve his order and then sends all the adjustments of the order via his mobile device to the corporate back-end system. Only after modifications are saved the supplier can start the fulfillment of the customer's order while the agent can visit the next customer. The deployment of mobile solutions allows overlapping the process of visiting the customers and the production or transportation process what improves service quality and increases customer satisfaction.
