Pricing metric is the most important part of your pricing structure in SaaS. It represents the amount of value your customers receive from your products.
You can see this from two different angles: from the user's perspective and from the business' perspective.
From the user's perspective: The more value the product provides, the more they are willing to pay.
From business perective, the more value the product provides, the more revenue can be derived.
Becasuse of this relationship, when pricing metrics go up or down, so does the revenue.
