Website Sale Invoice Address

In standard Odoo 16, an e-Commerce order forces the order contact to also be the invoice address. This module brings back the previous behaviour: when a customer checks out in the online shop, the invoice address is automatically taken from the invoicing address configured on the customer record, just like it works in the backend.

What changes for users:

• During checkout, the address shown as the invoice address is the customer's invoicing address, not necessarily the order contact.
• The "same as shipping" logic on the payment step now compares the shipping address with the invoice address, so the checkbox behaves correctly.
• The checkout summary displays the invoice address of the order.

Behind the scenes, the module adjusts how the online shop prepares and updates sale orders: when an order is created or updated from the website, the invoice address is recalculated from the customer's invoicing address. It touches the sale.order and website models and overrides two website templates (the payment step and the checkout page). No new menus or screens are added; the change is visible directly in the standard checkout flow.
