Automatically Add a Core Charge when Selling a Product that Requires a Core in Odoo Sales

In heavy duty diesel parts and auto parts industries, many parts need to include a core charge when invoicing the customer.
It is ideal to have the core charage added automatically when prepring the quote or sales order, to minimize human error, and to streamline the order writing process. ...We have built a custom automation in Odoo to accomplish this. 😁
Not to mention making it easirer on sales staff, since they won't need to be continually asking themselves if each part they're selling should have a core charge included or not.

Hi there. We added the core functionality by building a custom module.
