AI Operating System for Companies

What an AI operating system costs a 200-person company

Per-seat, per-action and per-company pricing produce very different bills for the same headcount. We worked through each model with published list prices.

At two hundred people, the per-seat line on an AI budget is the easiest to read and the least complete.

A finance team asked to budget for "an AI operating system" will find three incompatible price lists: per user, per action and per company. For a 200-person company the difference between them is large enough to change the decision, so the arithmetic is worth doing before the vendor meetings.

Why the bill is hard to forecast

Zylo's 2026 index reports that 78% of IT leaders faced unexpected charges tied to AI features or consumption-based pricing, and that 61% cut projects because of unplanned SaaS cost increases⁠1. The cause is structural: AI is increasingly sold by consumption, and consumption depends on how much work the AI ends up doing, which no one knows in advance.

Three pricing models, worked for 200 people

The figures below are our arithmetic on list prices published by each vendor on the access date. They exclude tax, discounts and implementation.

Per user: an AI layer on the suite. Microsoft 365 Copilot Business is $21 per user a month, paid yearly, for organisations of up to 300 users⁠23. For 200 users that is $50,400 a year, on top of the Microsoft 365 licences. Bundled with Business Standard it is $35 per user a month from 1 July 2026, or $84,000 a year including the suite⁠2. Agents that use work data and Copilot Cowork are billed by usage in addition⁠4.

Per action: metered agents. Salesforce sells Flex Credits at $500 per 100,000 and charges 20 credits for a standard agent action, which works out at about $0.10 per action⁠5. A company whose agents perform 50,000 actions a month would spend about $5,000 a month, or $60,000 a year, before Salesforce licences. The alternative, $2 per customer conversation, costs $120,000 a year at 5,000 conversations a month⁠5.

Per company: an owned platform. OpenLazarus prices the platform rather than seats: managed hosting from $150 a month, engineering support from $4,500 a month for 10 engineering credits, and a 5.5% fee on AI credits used⁠6. Those are starting prices. Its own ROI calculator, run with its default inputs for a 100-person company, shows annual costs of $346,800, of which $324,000 is engineering support (60 engineering credits), $12,000 AI credits and $10,800 hosting⁠7. A 200-person company should expect a quote rather than the starting figures, and the AI-Architect engagement that OpenLazarus recommends above 100 people is priced per engagement⁠6.

Comparing like with like

The table cannot be read as a league table. A per-user layer adds a cost and removes none; a platform that replaces tools removes some subscriptions and part of the outsourced work. OpenLazarus says its architects cut paid SaaS seats "from most of your employees to a few"⁠11, and its calculator offsets costs against cancelled software, insourced work and staff time⁠7. Those savings are the vendor's model, not measured results, and a finance team should test them against its own subscription list.

The costs vendors leave off the page

  • Security and compliance add-ons. Microsoft lists its Purview Suite at $10 per user a month and the Defender and Purview bundle at $15⁠2. At 200 users the bundle is $36,000 a year.
  • Usage above allowances. Copilot Studio enforces purchased capacity monthly; unused credits do not carry over, and exceeding capacity can lead to service denial⁠12. Salesforce Flex Credits do not roll over into later terms⁠5.
  • Implementation and people. Designing permission models, connecting systems and supervising agents takes staff time that rarely appears in a vendor quote.
  • The cost of a governance failure. IBM puts the global average cost of a data breach at $4.44 million, with $670,000 more for organisations with high levels of shadow AI⁠13.

Building the budget

  1. List current subscriptions and seats for the functions in scope, with renewal dates.
  2. Estimate volume, not only headcount: conversations, documents and agent actions per month.
  3. Price at least two models from the table, including usage and governance add-ons.
  4. Subtract only what will actually be cancelled, at its renewal date.
  5. Add a contingency for usage, and set budget caps or alerts where the platform supports them.

The end state is a budget the board can follow: one line per platform, the usage assumptions written down, the subscriptions to be retired named with their dates, and a quarterly check of actual usage against the plan. The main comparison shows which platforms publish enough to make that budget possible.

Questions buyers ask

How much does Microsoft 365 Copilot cost for 200 employees?

At the published list price for Copilot Business of $21 per user a month, paid yearly, 200 users cost $50,400 a year, on top of an eligible Microsoft 365 plan. Usage-based agents and Cowork are billed separately.

Why do enterprise AI vendors not publish prices?

Most price by negotiated contract, by usage or by the scope of an implementation. Of the seven platforms in our comparison, Glean, Gemini Enterprise and Palantir AIP showed no price on the pages we read, and WRITER showed plan structure without figures.

What hidden costs should a 200-person company budget for?

Implementation and integration, internal staff time to design and supervise agents, security and compliance add-ons, usage above included allowances, and the cost of running old and new tools side by side during the transition.
