eBill Postfinance Stock

This module extends the Postfinance eBill integration to include stock-related information on invoices. When an invoice is sent through Postfinance eBill, the system can now include details about the delivery, such as the products shipped and their quantities, directly in the eBill message.

The module works automatically once installed, as it is set to auto-install when both the eBill Postfinance and Sales Stock modules are present. It adds a new template for invoice lines that includes stock information, which is used when generating the eBill payload. This means that the eBill sent to customers will contain the stock-related details from the delivery.

No new menus or screens are added; the change is in the background when preparing the eBill message. The module touches the ebill.postfinance.invoice.message model, specifically the methods that prepare the Jinja environment and the payload parameters for Yellowbill (the eBill format). The stock information is pulled from the sales order's delivery, ensuring that the eBill reflects what was actually shipped.

This is useful for businesses that want to provide transparent delivery information to their customers through the eBill system, reducing disputes and improving customer service.
