Odoo does not automatically include shipping costs in sales orders, but it does provide features that allow you to set up and manage shipping costs for your sales orders.

To set up shipping costs in Odoo, you can follow these steps:

1. Go to the Sales module and click on the "Configuration" menu option.
2. Select the "Shipping Methods" option.
3. Click on the "Create" button to create a new shipping method.
4. Give your shipping method a name and select the delivery carrier that you want to use.
5. Under "Pricing," set the pricing rules for the shipping method, such as a fixed price, a price based on weight, or a price based on destination.
6. Save your changes.

Once you have set up your shipping methods, you can assign them to your sales orders. To assign a shipping method to a sales order, follow these steps:

1. Create a new sales order or open an existing one.
2. Click on the "Delivery" button in the top right corner of the page.
3. Select the shipping method that you want to use from the list of available methods.
4. Enter any additional delivery information, such as the shipping address and delivery date.
5. Save your changes.

Now, when you confirm the sales order, the shipping costs will be automatically calculated and added to the total cost of the order. You can also view and manage your shipping costs in the "Delivery Orders" menu under the Sales module.
