Fulfillment is inventory activity that happens in a fulfillment center or warehouse, including picking, packing, and shipping. Picking is the selection of products in one or more releases from a fulfillment center, packing is putting these products into shipping containers, and shipping is sending them to customers. A number of people work in a fulfillment center at one time, each with a different task or tasks to perform. The WebSphere Commerce Accelerator divides the most common tasks into roles, and these roles are assigned to users.

Products are configured for fulfillment in the Product wizard and the Product notebook. It includes options to track inventory, allow backorder, force backorder, release separately, and specify that the product is not returnable.
