A user interface for a computerized complex order processing system presents a list of products and services associated with an account, a list of quotes associated with the account, a list of orders associated with the account, and several user-selectable options. The options allow the user to transfer a service profile by defaulting the existing services at an old location to a new location; add, modify, and disconnect products and services the service profile, quotes, and orders associated with a selected account. The options further allow the user to accept a quote, convert the quote to a sales order, update the amount of revenue to be generated by a quote, approve an order, and submit the order for provisioning.
