Buying AI: The Procurement Playbook

AI is reshaping SaaS pricing models faster than procurement teams can adjust - here’s how to keep up.

Introduction

The less-obvious AI disruption: SaaS contracts

As vendors rapidly embed AI capabilities into their platforms, the inadvertent result has been that they have gained a stronger position in negotiations - leaving procurement and finance teams playing catch-up at a pace they can’t match.

We've had hundreds of conversations with companies across the globe on this topic, and the same questions have always appeared:

How are SaaS vendors restructuring pricing to monetize AI?
What new negotiation tactics and evaluation criteria should be applied?
How to spot ‘AI washing’?
What new security and compliance risks do AI features or ‘AI native’ tools introduce?

This report provides these answers, plus actionable insights and guidance to help avoid overspending, and secure maximum value from your AI investments.

The new world

AI and the 4 new economic principles of SaaS pricing

The core of all of this disruption is that traditional flat-fee or per-user pricing models fail to reflect the variable compute requirements and dynamic value of AI-driven functionality. 

Vendors have been quick to pivot, replacing legacy pricing frameworks with models that better align with their costs.

Outcome-based pricing

One of the most notable shifts is the rise of outcome-based pricing. In these models, charges are tied to specific business outcomes - such as successful customer support resolutions or qualified lead generation.

This structure can lower adoption barriers, removing limits on users or data input, and brings some security to those inexperienced in investing in AI.

However, in these structures, costs will inherently become variable. And strategic outcomes may shift, creating a risk of the contract's goals becoming redundant - putting additional SRM onus on procurement teams.

Negotiation Options
Set caps and floors

Establish maximum spend limits and minimum performance thresholds to control costs and ensure value.

Use blended pricing

Combine a base subscription with a lower cost-per-outcome fee.

Define outcome calculations

Demand transparency into how outcomes are calculated and redefine to what is valuable to you as necessary.

Include attribution clauses

Ensure costs are appropriately allocated and ratioed if humans play a role in generating outcomes.

Establish outcome timeframes

Agree on when outcomes are evaluated and when price adjustments apply.

AI as an upsell - and a lock-in risk

Vendors are increasingly offering AI features as premium add-ons, or embedding them into higher-tier subscriptions. 

While this adds the desired functionality, it often comes without guaranteed ROI given the relative infancy of AI features.

Bundling AI tools into existing ecosystems can also lead to Vendor Lock-In, particularly when time has been spent training AI tools to your needs, or when your data becomes tightly integrated into a single platform.

Negotiation Options
Secure bundling discounts

Negotiate favorable pricing for upsells or future add-ons.

Include data extraction clauses

Ensure Service Level Agreements (SLAs) are in place for data portability and platform exits.

New AI contract clauses

Vendors are frequently adding new clauses to their contracts - designed to enhance monetization and platform stickiness while limiting liability.

Data use obscurity

Vendors protect their IP by limiting visibility into how their AI models and features operate, and deliberately use vague, broad contractual terminology when outlining how customer data will be exactly used.

Intellectual Property (IP) rights

Vendors often claim ownership of AI-generated content - even if it's based on customer data. 

While customers view their data as their own IP, vendors are using this for ‘free’ to continuously train and improve their own model, boosting their product's value, attracting new customers and supporting renewals - meaning the vendor potentially stands to gain far more than the customer.

Broad performance metrics

Definitions of "performance" are shifting from specific guarantees to ambiguous outcome-based metrics.

This makes it far trickier for customers to nail down specific performance warranties and SLAs, and gives the vendor more leeway with performance-based financial uplifts and penalties.

Liability limitations

Contracts frequently include protections and indemnities for vendors against hallucinated (output that is presented as fact but is fabricated, incorrect or nonsensical) or harmful AI outputs. 

If built or deployed without suitable safeguards, this puts all the risk of using an inherently creative and independent ‘black box’ technology on the customer.

Negotiation Options
Request ‘Black Box’ clarity

Amend / define relevant contract clauses to gain sufficient transparency into how your data will be used for model training and evolution.

Ensure anonymity and confidentiality

Gain assurances that where your data is ingested by the tool, it will be anonymised and not disclosed to any other customers.

Define IP rights

Data ownership (vendor, customer, or both), and how data is used for model training, should be clearly outlined - with opt-out clauses for training.

Specify AI performance SLAs

Fulfilment metrics should be based around the exact outcomes you want to achieve.

Include data handling requirements

These should cover storage, deletion, and access.

The enterprise SaaS AI "moat strategy"

Large vendors are increasingly building integrated AI ecosystems - designed to lock customers into their platforms.

Take Salesforce, for example. Having acquired the popular comms tool Slack in 2021, they’re now repositioning it as the front-end for a suite of AI agents branded as Agentforce:

  • Slack AI: unified natural language search across Slack, Salesforce, and third-party tools
  • Canvas: shared whiteboards embedded directly into Slack channels
  • Salesforce Channels: CRM-native threads that bring opportunity data directly into Slack
  • Workflow automation: trigger Salesforce flows from inside Slack
  • Slack Enterprise+: a top-tier Stock Keeping Unit (SKU) now bundled with Agentforce

This seems compelling - strong features and capabilities that could offer substantial productivity and performance benefits. 

But in the process, Salesforce is also restricting third-party integrations - limiting which tools can and cannot access, store or index certain data (most notably Glean). This creates a closed-loop system designed to retain control and increase stickiness.

“These AI investments are more than just a tool purchase - they’re a bet on your strategic AI operating system for the next decade.

You can try to remain agnostic, but big players are aggressively locking down who can also access ‘their’ customers by controlling the data.”

Take back control from the start

The 6 new evaluation criteria for buying SaaS AI
"Do we have a clear objective and use case?"

AI investment has surged - enterprise spending grew 394% year-on-year. But without clear use cases, there's a high risk of wasted spend - already at epidemic levels for businesses.

Avoid adopting AI tools simply due to hype, or because a competitor has it. The primary focus should be the outcome, efficacy, performance and ROI. Ensure there are crystal clear reasons for their implementation - both on a departmental and wider company level.

“Can it deliver high performance and high ROI? What are the outcomes? What is this new AI tool going to replace? What’s it going to specifically do that isn’t being done already?

Ask probing questions, even if they are almost ‘anti-AI’. It’s about nailing the business case. If you're not clear, you're just buying into hype.”

Tom Mills
"Is our data up to scratch?"

AI is only as good as the data it’s fed. Common issues include:

Incomplete or inconsistent data
Siloed data sets
Duplicate records
Human bias in written content 

We all know the phrase 'junk in, junk out'.

Make sure that the data your new AI investment is going to rely on is fit for purpose before signing the contract. AI models will amplify flawed inputs, so make sure you have live-tested the proposed SaaS tool on your own data so you can see how suitable it is before committing fully.

"Are we ready?"

A poll in a recent Vertice webinar - attended by over 100 finance and procurement leaders - found that only 32% of organizations are actively implementing AI on a company-wide level.

This speaks to the number of barriers to AI adoption.

Does your preferred tool integrate with all your data platforms? Does the vendor's AI roadmap match your likely future needs? And the biggest barrier of all, are your teams prepared to use and trust it? 

We have seen AI SaaS contracts fail for all these reasons, and more.

"Are the teams willing and able to use AI?"

AI adoption isn’t just technical - it’s cultural. Without adequate training and change management, teams may underuse tools or seek unsanctioned alternatives.

Proper onboarding processes are instrumental in highlighting where and when AI can be best used, and where it shouldn't.

All the usual principles of change management and skills development will apply - finding champions, tackling resistance, being prepared to move slowly etc - especially as AI is arguably the most dramatic change to their day to day roles that most users will have seen.

“AI can do a lot, but without the right change management, internal alignment and the right documentation, it won’t do what’s intended. It still has to be powered, used and questioned by humans.”

"Are our security & compliance requirements suitable for AI?

Because AI tools integrate and learn from internal systems, they introduce new compliance and security risks that other technologies have never created.

Mitigation options include using anonymized, aggregated or ringfenced data; regular audits of tool integration and data access; and including AI-specific policies in your internal compliance frameworks.

"Is what we are buying really AI?"

Many vendors market basic automation or data analytics as AI, using the market hype to charge a premium.

Procurement teams must therefore be cynical, and certain that the new feature is worth the 'AI tax'.

“Vendors know AI is a buzzword.

We need to be careful, stay skeptical and look under the hood of any AI solution we encounter.”

Questions to ask:

How does your AI actually work?
What specific data is it trained on?
Can you provide a specific customer use case of your AI in action?
What were the results in terms of output and ROI?
What's the tangible value of your AI over a non-AI approach?

Getting ahead

Building AI-buying strategies into procurement workflows
Centralize intake

A user-friendly, customized and flexible single point of entry into the procurement process enables full control of all purchasing requests. 

This prevents shadow AI adoption - a potentially ruinous scenario for finances and security thanks to AI’s long integration tentacles - and enables the automation of low-risk approvals.

Companies like CloudHesive incorporated security compliance steps, including checks for SOC 2 Type 2 and ISO 27001 certifications, into their workflows through a centralized intake system.

Update workflows

Procurement processes can be orchestrated automatically based on pre-set criteria. This enables the company AI strategy to be baked into everyday procurement actions.

Workflows should be adapted for AI buying, especially:

AI specific benchmarks and pricing approvals - even more important given vendors’ new pricing models
Document scanning for AI contract clauses
New approval routing as new stakeholders may be required to confirm an AI tool’s suitability
Dedicated security and privacy steps

With AI requiring wholesale changes in data security and privacy, you need to ensure your workflows contain the following:

Updated compliance and security reviews and steps in the workflow to accommodate the new risks
Data privacy questionnaire for vendors should be updated to include how data is used for AI model training
Updated automated risk reviews with AI regulations
New requirements for legal approval, such as performance
SLAs, data protection and data opt-outs
