Methods, systems, and apparatus, including computer program products, for implementing a software architecture design for a software application implementing ad-hoc goods movement. The application is structured as multiple process components interacting with each other through service interfaces, and multiple service operations, each being implemented for a respective process component. The process components include an Accounting process component that records the relevant business transactions for valuation and profitability analysis; an Inventory Processing process component that handles the management of inventory and the recording of inventory changes and may provide services to maintain current stock, handling unit content, logistics operating unit content, and allocation content; a Site Logistics Processing process component that handles the preparation, physical execution, and confirmation of logistics processes within a site; and a Supply and Demand Matching process component that combines the tasks necessary to ensure that sufficient material receipt elements exist to cover material demand while taking available capacity into account.
