Customers pick **one plan**, which includes a set of features. ```typescript Products: ├── Pro Plan │ ├── Price: $29/month │ └── Price: $290/year ├── Enterprise Plan │ ├── Price: $99/month │ └── Price: $990/year ``` ## Unit-based pricing Charge a fixed amount per unit, optionally with included units or add-ons. ```typescript Product: Team Seats Base: 5 seats included, $50/month Extra seats: $10 per seat Customer orders 7 seats: Total = $50 + (2 × $10) = $70/month ``` > Charge a fixed price for each unit of a product or service.
