The AI tier you did not ask for is the biggest line on your 2026 renewal

The number that describes 2026

Software spend rose nearly 8% in a single year while the number of applications organisations run stayed flat, at an average of 305. Those two facts together are the year in one line. Nobody bought materially more software. The software they already had got more expensive.

Set that against the budget: IT budget growth is projected at 2.8%. A portfolio inflating at 8% inside a budget growing at 2.8% is not a procurement problem to be solved by sharper negotiation, it is a structural gap that has to come out of something. 61% of organisations report cutting projects because of unplanned SaaS cost increases, which is what closing that gap looks like in practice.

The prevalence is the part worth sitting with. 79% of IT leaders met a price increase at renewal in the past twelve months. This is not a handful of aggressive vendors; it is the normal condition of the market.

The mechanism, which is not really a price rise

A straightforward price rise is easy to see and easy to argue about. What happened through 2026 is subtler and harder to refuse: the tier you are on stops being sold.

The pattern runs like this. A vendor introduces an AI-enhanced tier above the one you bought. For a renewal cycle or two it is optional, priced at a premium, and adoption is modest. Then the tier below it is quietly retired for new business, and at your renewal the AI tier is presented as the natural continuation of your existing agreement. Declining means moving to a legacy plan with no roadmap, or moving vendor.

The published figures around this are consistent. ServiceNow's annual uplift is reported in the 5 to 10% range, with AI add-ons priced at 30 to 45% on top. Atlassian's Data Center increases, covering Jira and Confluence, have been reported between 15 and 40%. Enterprise software prices overall are rising around 8.4% in 2026. Gartner put the 2025 increases from several large vendors between 10% and 20%.

What separates this from ordinary inflation is that the buyer is paying for capability rather than for the same thing at a higher price, and the capability was not requested. That distinction matters at renewal, because it is the only ground on which the increase can be argued.

The charges that arrive after the contract

78% of IT leaders reported unexpected charges tied to consumption or AI features in the past year. That figure deserves more attention than the headline price rises, because it describes money that was never on the quote anybody approved.

AI features are metered in a way seats are not. A seat is predictable: you know how many people you employ. Tokens, documents processed, agent runs and generated assets are a function of how enthusiastically your staff use a feature the vendor is actively encouraging them to use. 42% of companies now monetise AI through usage-based or hybrid models, and Gartner projects 70% of leading SaaS vendors will offer consumption-based pricing by 2027.

The governance problem is that the people generating the spend are not the people who signed the contract, and the meter is on the vendor's side. Before agreeing to any consumption component, the questions worth settling in writing are: what exactly is metered, what the unit is in plain terms, whether there is a hard cap or only an alert, who receives the alert, and what happens when the cap is reached. A vendor unwilling to put a hard cap in the agreement is telling you something about how they expect the meter to run.

September 2026, in dates

Microsoft is not the worst offender here, but it is the most legible, because it publishes dates and prices where most vendors negotiate them privately. Three of them landed in the space of a fortnight, and together they are a useful worked example of how the pattern reaches a real invoice.

30 September 2026. Twelve promotional offers ended, including Microsoft 365 E5 discounts, the E3 three-year offer, Copilot discounts and the 20% Windows 365 Enterprise promotion. No price changed. The discount that had been holding the price down simply stopped, which produces an identical effect on the invoice and is much harder to contest, because nothing was increased.

1 October 2026. A 5% cost-of-capital uplift applies to annual-term subscriptions billed monthly, at renewal. This is a charge for paying monthly rather than annually. Worth modelling against your own cost of capital, because for many organisations paying annually now costs less than the 5%.

13 and 14 October 2026. Windows 10 Extended Security Updates Year 1 ends on 13 October, and Year 2 runs from 14 October 2026 to 12 October 2027 at €97.01 per device, roughly double Year 1. Organisations managing devices through Microsoft Intune or Windows Autopatch pay a discounted €71.82, about 26% less. Windows Server 2016 support also ends on 13 October, so the client and server deadlines land on the same day.

The ESU escalation is the honest version of what every vendor is doing less visibly. The price doubles annually by design, because the product is not meant to be bought twice.

Why every vendor moved at once

It is tempting to read a coordinated squeeze into this. The simpler explanation is that every vendor is facing the same arithmetic at the same time, and it is arithmetic they cannot avoid.

Traditional SaaS has near-zero marginal cost: one more user on an existing plan costs the vendor almost nothing, which is what made per-seat pricing work for twenty years. AI features break that. Every generated summary, every agent run, every document processed costs the vendor real money in inference, and that cost scales with usage rather than with headcount. A vendor who bundles AI into a flat per-seat plan is selling an uncapped liability at a fixed price.

So the pricing changes are not primarily opportunism. They are a margin structure being rebuilt in public, which is why they arrived across the market within a few quarters of one another and why they lean towards consumption. Global software spending is projected at $1.43 trillion in 2026, growing 15.1% year on year, and a meaningful part of that growth is cost being passed through rather than value being added.

This matters for negotiation, because it tells you which parts of an increase are movable. A vendor can discount a seat indefinitely; the marginal cost is near zero. A vendor cannot discount inference below what it costs them. If the uplift is a flat AI tier, there is usually room. If it is metered consumption, the floor is real and the negotiation should be about caps and visibility instead of about rate.

The multi-year commitment, which is worth less than it looks

The standard vendor answer to an AI uplift is a longer commitment in exchange for a better rate. Multi-year agreements rose from 23% to 38% of SaaS contracts, so the offer is clearly being accepted.

The data does not support it. Average savings at renewal run to 16.8%, and they break down by term in the opposite direction to the sales pitch: 12-month contracts average 16.4% savings, 24-month 14%, and 36-month 13%. Longer terms save less.

That looks backwards until you consider what the vendor is buying. The discount is not payment for volume, it is payment for removing your ability to leave. A buyer who can walk in twelve months has leverage every twelve months; a buyer locked for three years has leverage once. In a market where the product is changing this fast, the three-year price also locks you to a capability set that will look dated well before the term ends.

There are good reasons to sign multi-year, chiefly budget predictability and the cost of running a procurement cycle. Getting the best price is not among them.

What this looks like from a catalogue

One observation from maintaining pricing data across several thousand products, offered as a pattern rather than a statistic.

The published price is becoming less informative. Three changes, all visible in vendor pricing pages over the last year: a growing share of products show no price at all and route to a sales contact; the cheapest advertised tier increasingly excludes the feature the product is now marketed on; and the gap between the entry tier and the tier a business would actually need has widened.

The practical effect for a buyer is that comparing advertised prices compares the wrong thing. Two products at the same headline figure can differ by a multiple once the tier that includes AI, SSO and an API is priced. Any comparison worth acting on has to be made at the tier you would genuinely buy, with the consumption component modelled at your expected volume, and that is more work than a pricing page is designed to require of you.

It is also why "contact sales" is spreading. A published price is a commitment that constrains a vendor rebuilding its margin structure. Removing it restores the flexibility to price each customer differently, which is better for the vendor and worse for everyone trying to make an informed comparison.

What actually reduces the bill

Negotiation is the obvious lever and the weakest one. Two numbers point somewhere better.

Organisations use 54% of the SaaS licences they pay for, and licence waste averages $19.8M a year. Against a 10% uplift on a tool where half the seats are dormant, reclaiming the seats beats any discount you could negotiate, and it does not require the vendor's agreement. The uncomfortable part is that this is unglamorous internal work rather than a meeting where somebody wins.

Three things worth doing before the next renewal:

• Measure actual use per seat, not licences assigned. Assignment is an administrative fact; the last login is the one that determines whether a seat is worth renewing. Do it ninety days out, so there is time to act on what it says.
• Price the AI tier as a separate purchase. If it were sold standalone at the uplift amount, would you buy it? If the answer is no, the fact that it arrives attached to something you do want does not change the answer, and that is the argument to make at renewal.
• Find out what is expiring rather than rising. September's twelve Microsoft offers are the model: the most common cause of a jump is a discount ending, not a price changing. Discounts have end dates and those dates are in your paperwork. Nobody is going to remind you.

And the structural point underneath all of it: 3.67% of SaaS spend happens through expense channels, outside procurement entirely. Some proportion of the increase people are attributing to vendor aggression is software the organisation bought without noticing.

Questions people ask

Why did our SaaS costs rise when we did not add any tools?

Because the portfolio, not the count, got more expensive. Spend rose nearly 8% in a year while application counts stayed flat at around 305. The main drivers are AI-enhanced tiers replacing the plan you were on, consumption charges on AI features, and promotional discounts reaching their end dates.

Can we refuse the AI tier at renewal?

Sometimes, and it depends on whether the previous tier is still sold. Where it is, staying costs a conversation. Where it has been retired for new business, the options are a legacy plan with no roadmap, the higher tier, or a different vendor. Ask specifically whether your current tier remains available for renewal, and get the answer in writing before you negotiate anything else.

Are multi-year contracts cheaper?

Less than the pitch suggests. Average renewal savings run 16.8% overall, but 12-month agreements average 16.4% against 13% for 36-month ones. Longer terms save less, because the discount is payment for removing your ability to leave rather than for volume.

What is the 5% CSP uplift?

A cost-of-capital charge Microsoft applies from 1 October 2026 to annual-term subscriptions billed monthly, applied at renewal. It is a charge for spreading payment rather than paying annually, so it is worth comparing against your own cost of capital before accepting it.

How much is Windows 10 ESU Year 2?

€97.01 per device for standard coverage from 14 October 2026 to 12 October 2027, roughly double Year 1. Organisations managing devices through Intune or Windows Autopatch pay €71.82, about 26% less. Year 1 ends on 13 October 2026, the same day Windows Server 2016 support ends.

What is the fastest way to reduce software spend?

Reclaiming unused licences, in most cases. Organisations use 54% of the licences they pay for and waste averages $19.8M a year, so on a tool where half the seats are dormant, removing them beats any discount available by negotiation and does not require the vendor to agree.
