The SaaS subscription model built the modern software industry. It gave vendors predictable revenue and gave businesses seemingly manageable costs. For a while, it worked brilliantly for both sides. But in 2026, the cracks are impossible to ignore. CFOs across the UK are staring at software bills that have ballooned far beyond original projections, and many are asking a blunt question: what exactly are we paying for?
The backlash has been building for several years. Gartner research has consistently flagged SaaS sprawl as a top concern for IT leaders, with the average mid-sized enterprise now running well over 100 software subscriptions simultaneously. Renewal cycles arrive with price increases baked in, usage data shows swathes of licences sitting idle, and vendor lock-in makes switching painful enough that many businesses simply absorb the cost. That dynamic is finally shifting.
Why the Traditional SaaS Subscription Model Is Losing Its Grip
The core problem is misalignment. Subscription pricing charges you for capacity rather than outcomes. A team of 50 might pay for 50 seats of a project management tool and use 30 of them actively. The vendor wins; the customer loses. When budgets were loose and growth was the only metric that mattered, this was tolerable. In a tighter macroeconomic environment, it is not.
There is also the AI variable. As vendors rush to embed AI features into every tier of their platforms, they have used it as justification for another round of price hikes. Microsoft 365 Copilot, Salesforce Einstein, and similar offerings are bundled at a premium, regardless of whether individual users will ever touch them. Paying for AI capability you neither want nor use has become a genuine frustration at the procurement level.
Consumption-Based Pricing: Paying for What You Actually Use
The most credible challenger to the flat-subscription model is consumption-based pricing, sometimes called usage-based pricing. Instead of a fixed monthly fee, you pay based on API calls, data processed, transactions completed, or active users in a given period. Snowflake pioneered this approach in data infrastructure and demonstrated that enterprise customers would embrace it if the transparency was genuine.
For IT decision-makers, consumption-based models offer something subscriptions rarely do: cost that scales directly with value received. When business slows, software spend contracts automatically. When it grows, expansion happens without a renegotiation. The downside is financial unpredictability, which is why many vendors now offer hybrid structures: a committed base tier with consumption overage above a threshold. It is a reasonable middle ground, and procurement teams are increasingly insisting on it during contract negotiations.
Outcome-Based Models: The Boldest Shift in B2B Software
More radical still is outcome-based pricing, where the vendor charges only when measurable business results are delivered. An accounts receivable automation platform might charge a percentage of cash collected faster than baseline. A fraud detection tool might take a cut of losses prevented. This model puts vendor and customer incentives in genuine alignment, which is why it generates significant interest despite being harder to implement at scale.
Several UK-based fintech and RegTech firms have moved in this direction, particularly in areas like compliance automation and revenue recovery. For a CFO, outcome-based pricing is conceptually appealing because the ROI calculation is embedded in the contract itself. The practical complexity lies in agreeing on measurement methodologies and baseline metrics before go-live, which requires a more rigorous procurement process than signing a standard SaaS order form.
Embedded AI Pricing: The New Variable CFOs Need to Understand
A third disruption is reshaping the stack from a different angle. Rather than replacing subscription logic entirely, embedded AI models are changing what software does per pound spent. Platforms that once required multiple human operators can now run leaner teams, which shifts the ROI calculus even when the subscription cost stays flat or rises modestly.
The smarter vendors are pricing AI capability as a separate consumption layer, charged per interaction or per task completed. This is actually fairer than bundling, because businesses that derive real value from AI features pay proportionately, while those that do not are not cross-subsidising heavy users. IT leaders evaluating new contracts in 2026 should be asking vendors precisely how AI usage is metered and billed, before signing anything.
Interestingly, the pressure to rethink software spend has also nudged some businesses towards more local, modular tooling. Just as consumers have started to find local products as an alternative to large platform ecosystems, some SMEs are building leaner software stacks from specialist tools rather than relying on one bloated suite that does everything adequately but nothing brilliantly.
What This Means for CFOs and IT Decision-Makers Right Now
The immediate practical implication is that passive renewal is no longer acceptable strategy. Every SaaS contract coming up for renewal deserves a genuine usage audit. Which licences are active? Which features are actually used? What would a consumption-based alternative cost at current usage levels? These are questions that finance and IT teams should be answering together, not separately.
Negotiating leverage exists that many businesses fail to use. Vendors facing churn pressure are often willing to restructure contracts, introduce usage-based tiers, or offer outcome-linked pilots if the alternative is losing the account entirely. UK businesses in particular have found that citing competitive alternatives, even in early evaluation, shifts the dynamic meaningfully.
The SaaS subscription model is not disappearing overnight. The installed base is enormous, the switching costs are real, and plenty of tools still justify a flat fee when adoption is genuinely high. But the era of uncritical renewal, of paying for shelfware because renegotiating felt like too much work, is over. The businesses that treat software spend with the same rigour they apply to any other operational cost will be the ones that extract genuine competitive advantage from the next generation of pricing models. The vendors that fail to adapt will find that patience among CFOs has worn very thin indeed.
Frequently Asked Questions
What is consumption-based SaaS pricing and how does it differ from subscriptions?
Consumption-based pricing charges businesses based on actual usage, such as API calls, data volume, or active users in a period, rather than a fixed monthly or annual fee. Unlike the traditional SaaS subscription model, costs scale up or down with real demand, which gives finance teams greater control and makes the relationship between spend and value much clearer.
Are SaaS vendors actually moving away from flat-rate subscriptions?
Many are, particularly in infrastructure, data, and AI tooling. Vendors like Snowflake and AWS have demonstrated that enterprise customers will accept usage-based models, and a growing number of application-layer SaaS companies are introducing hybrid structures that blend a committed base fee with consumption overage. The shift is gradual but accelerating as customer pressure increases.
How should a CFO approach a SaaS contract renewal in 2026?
Start with a usage audit: establish which licences are active, which features are genuinely used, and what idle capacity is costing the business. Use that data as negotiating leverage, and actively ask vendors whether consumption-based or outcome-linked pricing options exist. Many vendors will offer restructured terms rather than risk losing the account, especially in a competitive market.
What is outcome-based SaaS pricing and which industries use it?
Outcome-based pricing ties software costs to measurable business results, such as revenue recovered, fraud prevented, or processing time saved, rather than to usage or seats. It is most common in fintech, RegTech, accounts receivable automation, and revenue intelligence platforms. The model requires clear baseline metrics and agreed measurement methods before implementation, making procurement more complex but ROI more transparent.
Is SaaS sprawl still a major problem for UK businesses?
Yes. Most mid-sized UK enterprises are running well over 100 software subscriptions, many of which overlap in functionality or sit largely unused. SaaS sprawl inflates IT budgets, creates security surface area, and makes it difficult to enforce data governance. Regular software audits, centralised procurement oversight, and stricter renewal criteria are the most effective tools for managing it.
