The Product Order Capture and Validation component addresses the means of capturing what a customer wants to order, based on the CSP Product Catalog. This component permits to choose the configuration of the product offerings and products desired, to provide a quote, to check the eligibility of the customer order, and to complete it with information needed such as the related parties or associated the billing account and the delivery appointment if needed. This component is globally in charge of these quote management, order capture and validation steps, using dedicated components (e.g., Offering Configurator, Service Qualification, Party Mgt) when needed. After the delivery of the customer product order items, this component is also in charge of the commercial closure of the order. It includes update of the Product Inventory (status and starting/end date of tariffs and discounts) and potential commercial rules control (e.g., receipt of the contract document signed by the customer)
