Bill splitting is useful in Bar/Restaurant. Customers can split their bill using this option. Odoo 13 has this feature in its POS module.
To activate bill splitting users have to configure the option for bill splitting in settings of Bar. We have to check the option Bill Splitting in the settings and save it. By starting the new session, we can see the floors and we can select the order for a particular table. If one person in that table order a product and another person ordered another product, we can use bill splitting in the order window to split the bill. By clicking the Split button a new window is opened here we can see the complete products in that order.
