In The Bike Company, now that the goods issue has been posted, billing needs to be performed. Billing a sales order is the twelfth and last step in the overall MTO process.
In this step, you invoice a customer for products or services that you have sold and delivered, and you request payment for these products or services.

When a sales order is billed, one or several billing documents are created. A billing document is always created with reference to a preceding document, such as a sales order or a delivery document. Data from the reference document is then copied to the billing document’s header and items.
Note
Settings in the implementation activities of your SAP S/4HANA Public Cloud system control what data is copied from a reference document to a billing document and how it is copied.
In general, a billing document is structured into billing header and billing items. The billing header contains general data that is valid for the entire billing document, including, for example, the document number, the billing date, the net value of the entire billing document, price elements, or terms of payment and incoterms. An item contains, for example, the material, the billing quantity, the net value of the individual item, and price elements relevant for the individual items.
From the reference document, the billing type can be copied into the billing document header. The billing type dictates what type of billing document is created, defines the entire billing document, and controls how the system processes it. In The Bike Company, the billing type F2 (delivery-related or sales-order-related invoice), which is entered in sales order item creation, is used. As a result, an invoice with reference to a sales order can be created.
Note
When activated in the billing settings, as soon as an invoice is created, the billing data is automatically posted in financial accounting, where a corresponding journal entry is created. In that journal entry, the customer receivables account is debited and the revenue account and output tax account are credited. The posted revenues are assigned to the respective profitability segment in margin analysis.

After billing the sales order, its process flow diagram is updated. The process flow diagram can be accessed, for example, from the Track Sales Order app.

A billing document can be created in the Create Billing Documents app. Additionally, in this app, a process flow for the created billing document is displayed. From the process flow, you can navigate, for example, to the created accounting document.
