Per user pricing

Per user pricing charges customers based on the number of individuals who have access to a service. This model is prevalent in software and online tools, where each user has their own login and account. It's a straightforward way to scale pricing based on the number of users.

Example: Slack offers a user-based pricing model. They charge a certain amount per user, giving businesses the flexibility to pay based on their size and specific communication and collaboration needs.

While per user pricing is a common model in software and online tools, it can become more nuanced when there are different types of users to consider. For example, Figma offers both free viewer roles and paid editor roles, which can make pricing more nuanced depending on the specific needs of the business.
