Pricing is the highest-leverage decision in SaaS. A 20% price increase has a larger impact on margin than a 20% reduction in CAC. Most founders underprice because they are afraid of churn — and then work twice as hard to acquire customers who were never willing to pay full value.

Why Pricing Is a Product Decision, Not a Finance Decision

Most founders treat pricing as something to figure out after the product is built. This is backwards.

Pricing shapes who buys your product, how they use it, and what success looks like for them. A product priced at €29/month attracts a different customer than the same product at €299/month — and those customers have different support requirements, different churn profiles, and different growth potential. Building a product without knowing what segment it is priced for means building without knowing who you are building for.

Pricing also determines your go-to-market motion. A product at €29/month cannot afford a sales team — it has to grow through self-serve acquisition. A product at €2,900/month can afford sales, and might require it. The pricing model determines the economics of growth.

Get pricing directionally right before you build. It will not be perfect — pricing is always iterative — but “we have not thought about this yet” at the launch stage is a strategy problem, not a temporary gap.

Flat-Rate Pricing

Flat-rate pricing means one product, one price, for all customers. Basecamp is the most cited example: $99/month for unlimited users and projects.

The appeal is simplicity. One price to communicate, one plan to support, no upgrade conversations, no per-seat tracking. Customers know exactly what they will pay.

The problem is that flat-rate pricing leaves money on the table from customers who would have paid more, and it charges too much for customers who would otherwise be a good fit at a lower price. You optimise for one segment by definition.

Flat-rate works well when your product is genuinely one-size-fits-all and your target customer is clearly defined. It works poorly when you serve multiple segments with meaningfully different willingness to pay.

For early-stage products, flat-rate’s simplicity is an asset. You can move to more complex pricing once you understand your segments well enough to design tiers that reflect real value differences.

Per-Seat Pricing

Per-seat pricing is the default for most B2B SaaS, and for good reason: it is easy to explain, it scales naturally with the customer’s team size, and it creates a direct relationship between customer growth and your revenue.

The pricing mechanic is simple: €X per user per month. The execution complexity is moderate: you need user tracking, seat counts in your billing system, and a process for handling overages and additions.

The main critique of per-seat pricing is that it creates an adversarial dynamic around user accounts. When adding a user costs money, teams share logins, managers resist onboarding new employees, and adoption suffers. This is a real problem, and it is more severe in price-sensitive markets or where your product does not deliver daily active value to every user.

The antidote is pricing high enough that the per-seat cost is justified by the per-user value. If your product saves each user two hours per week, and an employee’s time is worth €50/hour, the ROI conversation is easy at €30/seat/month. At €5/seat/month, the conversation still works but customers are less likely to have it — they will just pay and forget.

Usage-Based Pricing

Usage-based (or consumption-based) pricing means customers pay based on how much they use — API calls, transactions, rows processed, emails sent, GB stored.

The appeal is alignment: customers pay for what they use, which reduces the barrier to adoption and creates a natural expansion motion as usage grows. Stripe, Twilio, and AWS built enormous businesses on this model.

The challenge is revenue predictability. Usage-based revenue is inherently variable, which complicates financial planning and makes it harder to manage cash flow. It also requires more sophisticated billing infrastructure — you need to meter usage accurately, handle billing for partial periods, and communicate clearly about what triggers charges.

Usage-based pricing works best when:

• Usage is a reliable proxy for value (you are billing for transactions completed, not just sessions started)
• Usage varies significantly between customers (flat-rate would either undercharge heavy users or block light users)
• The cost to deliver the product scales with usage (infrastructure, compute, AI inference)

For most early-stage SaaS products, pure usage-based pricing is the wrong starting point. The billing complexity is not worth the sophistication until you have proven that usage correlates with value for your specific product.

Tiered Pricing

Tiered pricing is the most common model for growth-stage SaaS. It means different plans at different price points, with different features or limits in each tier.

A typical three-tier structure:

• Starter: Core features, limited usage, self-serve support — priced for small teams or individuals
• Growth: Full features, moderate limits, email support — priced for growing companies
• Enterprise: Unlimited or custom limits, dedicated support, SSO, compliance features — priced for large organisations

The tiers should reflect genuine differences in how different customers use and value the product — not artificial feature locks designed to push customers into higher tiers. Customers notice when a missing feature feels like a ransom rather than a legitimate product differentiation.

Pricing your tiers is where most founders get into trouble. The tendency is to price Starter too low (making it the only viable option for most customers), Growth in the middle without clear differentiation, and Enterprise with a “contact us” that nobody clicks.

Price Starter at the level where a serious, paying customer would not feel over-charged. If Starter customers are churning because the product is not valuable enough to justify even a low price, the problem is value, not pricing. If Starter customers are churning because they quickly outgrow it, that is a good problem — it means your tier boundaries are in the right place.

Freemium

Freemium is not a pricing model. It is a customer acquisition strategy.

A freemium product has a permanently free tier and a paid tier. Free users get real value from the product; paid users get more. The free tier exists to generate awareness, word-of-mouth, and organic growth — not to generate revenue directly.

Freemium only works when:

• The cost of serving free users is low enough to be subsidised by paid conversion
• Free users create value for the business beyond their own potential conversion (virality, referrals, marketplace liquidity)
• The conversion path from free to paid is clear and activated by real product usage

Freemium fails when free users consume significant support, infrastructure, or operational cost without converting at a rate that covers that cost. Many SaaS products have tried freemium and found that it produces a large base of active free users and a small paid conversion rate — net result is negative unit economics.

The question to ask before implementing freemium: “If 95% of free users never pay, does the business still benefit from having them?” If the answer is no, freemium is not the right acquisition strategy.

How to Choose

For most B2B SaaS products in the €10K–€100K ACV range, tiered pricing with per-seat elements in each tier is the right model. It is flexible enough to serve multiple segments, clear enough to communicate in sales conversations, and complex enough to capture value across customer sizes.

Start simpler than you think you need. A product with one clear pricing structure that customers understand will convert better than a sophisticated model that requires a 10-minute explanation. You can add complexity as you understand your customers better.

The biggest pricing mistake is underpricing because you are afraid of rejection. Price represents positioning. A product that costs €29/month signals something different than a product that costs €299/month, regardless of what the features actually are. Charge what your product is worth to the customers who value it most, and build everything else — positioning, sales motion, support model — around that choice.

If you are building a SaaS product and want to think through pricing as part of the overall product architecture, we are worth talking to. Understanding how a product will be monetised shapes decisions about the product itself — it is not a question to defer until after launch.
