SaaS pricing models explained

Per-seat pricing

You pay a fixed price for each user who has access. Slack, Asana, and most CRMs use this model. It is simple to understand: $12 per user per month means a team of 10 costs $120.

When it works well: Teams where every user actively uses the tool daily. If you have 10 seats and all 10 people log in regularly, per-seat is fair.

When it hurts: Teams where some users only need occasional access. Paying $12/mo for someone who logs in once a quarter is a waste. Watch for tools that count "viewers" or "read-only" users differently — some charge full price, others offer reduced viewer seats.

Budget tip: Multiply the per-seat price by your expected headcount in 12 months. If you plan to hire aggressively, per-seat costs can balloon. Negotiate volume discounts above 25 seats.

Usage-based pricing

You pay based on consumption: API calls, emails sent, data stored, or events tracked. Twilio, Snowflake, and most analytics platforms use this approach.

When it works well: Early-stage companies with low volume. You start small and only pay more as you grow. The cost scales with revenue, which feels fair.

When it hurts: When usage spikes unexpectedly. A viral blog post, a marketing campaign, or an engineering bug can cause usage to 10x overnight — and so does your bill. Always set up billing alerts and understand the overage structure.

Budget tip: Ask for committed-use discounts. Most usage-based vendors offer 20-40% off if you commit to a minimum monthly spend. This gives you predictability without losing the benefits of the model.

Flat-rate pricing

One price, unlimited users (or very generous limits). Basecamp is the classic example. You pay $49/mo and your whole team uses it — whether that is 5 people or 50.

When it works well: Growing teams who want cost predictability. No nasty surprises when you add your 20th user.

When it hurts: Solo users or very small teams. Paying $49/mo when you are the only user is expensive compared to a per-seat tool at $12/mo. The flat-rate model only becomes economical once you have enough users to bring the per-head cost below alternatives.

Freemium

A free tier with limited features, plus paid plans that unlock more. Notion, HubSpot, and Figma all follow this model. The free tier is the product demo — you experience the tool before paying.

When it works well: Always worth testing. The free tier lets you validate fit without risk. Some free tiers are genuinely useful long-term — see our free tools guide for the best ones.

When it hurts: When the free tier is deliberately crippled to frustrate you into upgrading. If you hit the limits within the first week, the free plan is marketing, not a product.

Contact sales / custom pricing

No public pricing. You fill in a form, talk to a sales rep, and get a custom quote. Enterprise tools like Salesforce Enterprise, Workday, and Veeva use this approach.

The reality: This almost always means annual contracts, minimum commitments, and a price that depends on how well you negotiate. Come prepared with competitor pricing, your team size, and a clear budget ceiling. Do not let the sales process drag beyond two weeks.

Which model is best?

The best pricing model is the one that aligns cost with value. If you are paying more as your team grows and gets more value — that is fair. If you are paying more because a vendor designed pricing to punish growth — that is a sign to look at alternatives.
