Pricing model is one of the highest-leverage decisions in B2B SaaS. It determines your sales motion, CAC, NRR, and the size of company you can sell to. OpenView's 2024 SaaS Benchmarks study provides the most comprehensive data.
The Four Primary Models
1. Per-Seat (User-Based)
How it works: Price based on number of users. $50/user/month, for example.
Examples: Salesforce, HubSpot, Monday.com, Slack
Growth metrics (OpenView 2024):
- Median ARR growth: 35%
- Median NRR: 108%
- Median gross margin: 73%
Best for: Collaboration tools, CRM, project management — anything where value scales with users.
Challenge: Sales ceiling at "we only need 10 seats." Expansion tied to hiring, not business growth.
2. Usage-Based (Consumption Model)
How it works: Price based on what customers use — API calls, transactions, data volume, minutes.
Examples: Twilio, Stripe, AWS, Snowflake, OpenAI
Growth metrics:
- Median ARR growth: 48%
- Median NRR: 104% (lower than seat-based despite growth)
- Median gross margin: 68%
Best for: Infrastructure, APIs, communications, AI — usage expands with customer success.
Challenge: Revenue uncertainty (hard to forecast), NRR pressure when usage declines.
3. Flat Rate (Subscription)
How it works: Fixed price regardless of users or usage.
Examples: Basecamp ($99/month for everything), Notion (old model)
Growth metrics:
- Median ARR growth: 28%
- Median NRR: 100-103%
- Median gross margin: 71%
Best for: Simple tools targeting small businesses; early-stage to simplify sales.
Challenge: Revenue ceiling per customer. Power users generate the same revenue as light users.
4. Tiered/Feature-Based
How it works: Price tiers unlocking features. Starter/Pro/Enterprise.
Examples: Most modern SaaS companies use this as the default model
Growth metrics:
- Median ARR growth: 38%
- Median NRR: 112%
- Median gross margin: 75%
Best for: Wide range of customer segments; natural upgrade path to higher tiers.
Choosing Your Model: The Decision Framework
| Question | Per-seat | Usage-based | Tiered |
|---|---|---|---|
| Value tied to # users? | ✓ | ✓ | |
| Value tied to volume/usage? | ✓ | ||
| Wide range of customer sizes? | ✓ | ||
| Enterprise sales motion? | ✓ | ✓ | |
| Self-serve/PLG motion? | ✓ | ✓ | |
| High gross margins (>75%)? | ✓ | ||
| Infrastructure/API product? | ✓ |
Pricing Level: The "Value Metric" Framework
Regardless of model, the pricing metric should align with how customers derive value:
| Product | Wrong metric | Right metric |
|---|---|---|
| Zoom | Per meeting | Per host seat |
| Stripe | Per developer | Per transaction |
| HubSpot | Per feature | Per marketing contact |
| Snowflake | Per database | Per compute unit |
Test: As a customer grows and gets more value from your product, does your revenue increase proportionally? If yes, you have the right metric.
The Enterprise vs. SMB Pricing Difference
| Dimension | SMB pricing | Enterprise pricing |
|---|---|---|
| Published pricing | Yes (website) | No (negotiate) |
| Typical ACV | $1K-$15K | $30K-$500K+ |
| Contract length | Monthly/annual | Annual/multi-year |
| Primary value driver | Features | Security, SLAs, support |
| Price sensitivity | High | Lower |
| Decision maker | Practitioner | Procurement/C-suite |
Most SaaS companies need both motions. The tiers can serve both:
- Starter/Pro → Self-serve SMB (price published)
- Enterprise → Negotiated (custom contract, MSA, SOC 2, SLAs)
NRR by Model (The Real Story)
NRR (net revenue retention) is the ultimate efficiency metric:
| Pricing model | Top-quartile NRR | Median NRR |
|---|---|---|
| Tiered feature | 130%+ | 112% |
| Per-seat | 120%+ | 108% |
| Usage-based | 140%+ | 104% |
The usage-based paradox: Top-quartile usage-based companies have the highest NRR (usage expands rapidly with success). But the median is lowest because usage can also decline. Usage-based has higher variance — it amplifies both success and failure.
Freemium as a Pricing Strategy
Freemium is not a pricing model — it's a distribution strategy. Adding a free tier to any pricing model:
- Increases trial volume by 100-500%
- Reduces direct sales cost
- Requires conversion rates to compensate (see freemium conversion rate data)
Freemium math check: If 3% of free users convert to $50/month paid, and free user infrastructure costs $1/user/month, you need 1,667 free users per $2,500 revenue. Is that feasible with your CAC for free users?
