What is one of the main advantages of using an information system for order fulfillment?

Using an information system for order fulfillment is particularly advantageous because it organizes information about customers efficiently. This efficient organization enables businesses to track customer preferences, order histories, and behavior patterns. Such insights facilitate personalized marketing strategies, improved customer service, and can streamline repeat order processes. By having instant access to accurate customer data, retailers can anticipate needs, ultimately enhancing the overall shopping experience and fostering loyalty.

The other options, while they may involve aspects of business operations, do not encapsulate the primary advantage of an information system in the context of order fulfillment. For instance, reducing shipping costs or increasing the number of suppliers pertains more to logistics and supply chain management, while eliminating customer service roles could diminish the quality of customer interaction and support, which is contrary to the aim of improving order fulfillment efficiency.
