Invoicing Integration Overview
Siebel invoice integration is designed for companies that rely on back-office billing and accounting applications to generate invoices for products sold and services rendered. The invoice retrieval business process assumes that the billable source data (billable time, expenses, and materials) has been sent from the Siebel application to a billing application for invoice processing.
After generating a final customer invoice, the third-party invoicing application can publish the invoice data as an XML file. This XML file is then passed to the Siebel application, which updates the Invoice business object, populates the base tables with the invoice data, and then displays the invoice in the Invoices views.
This functionality assists Siebel users with answering inquiries from customers about their invoices. An end user can view a customer invoice in the Siebel application, without needing to access the third-party invoicing application.
To integrate with an invoicing application, you use the Siebel Invoice business service, of type Data Synchronization, and the prebuilt Siebel Invoice Application Services Interface (ASI).
For more information about how to configure, use, and modify integrations based on ASIs, see Application Services Interface Reference.
