To create a new product type with its own custom pricing logic, you need to consider the following developments:
Content of the etc/product_types.xml file. This file will define the name, label, modelInstance, and priceModel of the new product type. The modelInstance will specify the custom type model that extends from the abstract Product Type model. The priceModel will specify the new price model that extends \Magento\Catalog\Model\Product\Type\Price.
Custom type model extended from the abstract Product Type model. This model will implement the logic and behavior of the new product type, such as how to prepare product for cart, how to process buy request, how to check product options, etc.
New price model extended \Magento\Catalog\Model\Product\Type\Price. This model will implement the custom pricing logic for the new product type, such as how to calculate final price, tier price, minimal price, etc.
