SaaS Pricing Models Explained: Per Seat, Usage-Based, Tiered, and More

Pricing is one of the most important decisions for a SaaS business, and it affects how the product must be built. Here are the common models and what each means for you and your customers.

Flat rate

One price for everything. Simple to explain and build, but it leaves money on the table with large customers and may be too expensive for small ones.

Tiered plans

Several plans, such as Starter, Growth, and Business, with increasing features or limits. This is the most common model because it serves different customer sizes.

Per seat

Customers pay for each user. Revenue grows as customers' teams grow, but it can discourage them from inviting colleagues.

Usage-based

Customers pay for what they use: messages sent, documents processed, or API calls. This aligns price with value, but revenue is less predictable and customers need clear visibility into usage.

Freemium and free trials

• Freemium: a permanently free plan with limits, designed to convert some users to paid plans.
• Free trial: full access for a limited time, then payment is required.

Hybrid models

Many products combine approaches, such as tiered plans with included usage and charges for extra usage. Hybrid models are flexible but require careful billing logic and clear communication.

What pricing means for your software

• Plans and entitlements must be modelled explicitly, so features can be switched on or off per plan.
• Usage must be measured accurately if you charge for it.
• Customers need billing pages, invoices, and upgrade paths.
• Changes to pricing should not require changes to feature code.

Build pricing as configuration, not code, so you can experiment without a rebuild.

Start simple

Early on, choose a simple model you can explain in one sentence, and design the system so you can change it later. MOKRIN builds SaaS billing with flexible plans and entitlements, so pricing can evolve as you learn.
