Packages and Custom Order Post Type

1. I have a prepaid package system : In which suppose if the customer pays me 999/- I offer them a service worth 1200/-, so 1200/- rupees shall be added to the wallet on payment of 999/- . How could I achieve this.

2. By default WooCommerce create a shop-order post type for the orders page which is then posted via checkout, I was contemplating, since I do not have a typical checkout page only a booking page, is it possible to create a custom order post type and post the wallet order on those post type using the checkout page.
