Methods, systems, and apparatus, including computer program products, for implementing a software architecture design for a software application implementing self-service procurement used to procure goods and services 'ad hoc' by requests from within an organization. The application is structured as multiple process components interacting with each other through service interfaces, and multiple service interface operations, each being implemented for a respective process component. The process components include an Accounting process component, an Internal Request Processing process component, a Purchase Request Processing process component, a Purchase Order Processing process component, a Goods and Service Acknowledgement process component, a Supplier Invoice Processing process component, a Payment Processing process component, an RFQ Processing process component, and a Due Item Processing process component.
