Microsoft Copilot billing is going metered by default. What to set before Dec. 1

What Microsoft reported on Oct. 28

Microsoft reported its first quarter of fiscal 2027 on Oct. 28. Revenue was $92.3 billion, up 19%, and Microsoft Cloud revenue was $63.9 billion, up 30%. The press release didn't mention Copilot at all. The details came on the call.

On the earnings call, CEO Satya Nadella said Copilot daily users were up nearly 50% from the prior quarter and more than 5 times from a year ago. He said the number of customers with more than 50,000 Copilot seats grew more than 8 times in a year. And he said the number of Copilot customers paying for credits through usage-based billing grew more than 75% in the quarter. Those are Microsoft's own numbers, and none of them is a count of paying seats.

That gap got noticed. When an analyst asked about seats, CFO Amy Hood said Microsoft did not disclose an update on the Copilot number this quarter. She also said results were partly offset by weaker sales of Microsoft 365 E3 and stand-alone products.

As reported by UC Today, Microsoft first gave a paid-seat count of 15 million in January, more than 20 million in April and over 30 million in July. Forrester analyst J.P. Gownder called the January number "disappointing uptake of the tool," according to Computerworld via UC Today. Since then, Microsoft has talked more about usage and less about seats.

The part that reaches your office: metered billing by default

The bigger change for a mid-size company is in a quieter place. In its October Partner Center announcements, Microsoft told its resellers that starting Dec. 1, 2026, usage-based billing will be on by default for new Microsoft 365 Copilot Business licenses bought through the Cloud Solution Provider (CSP) program. CSP is the reseller channel. If your IT provider or managed service provider bills you for Microsoft 365, you're probably buying through it.

Here is what the notice says:

• Pay-as-you-go is the default. It covers what Microsoft calls usage-based experiences, including Copilot Cowork, Work IQ APIs and GitHub Copilot Harness.
• The default limit is 4,000 Copilot Credits per user per month. Admins can change it. Microsoft's own example: a company with 100 Copilot Business users could use up to 400,000 credits a month under the default limit, billed on actual use.
• It starts in some countries first. It won't be available at first in 11 markets, including France, Germany and Spain. The U.S. is not on that list.
• Existing licenses don't change. The notice says no action is required for existing subscriptions. The old "(add-on)" offers stop being sold through CSP on Dec. 1, but Microsoft says end of sale isn't end of life: current customers can renew and change seat counts.

From the same date, new Copilot offers no longer need a base Microsoft 365 subscription, and Microsoft says they're priced the same as the current offers.

A default limit is a decision someone at Microsoft made for you. Make it yourself.

Why this matters more than the seat count

For years, software budgets at a 100-person company were simple. You paid per seat and the bill was the same every month. Metered billing works more like your electric bill. That's fair when the work is real: an agent that drafts 300 order confirmations should cost more than one that drafts three. But it makes the bill harder to predict, and the person who sees the bill is usually not the person who turned the feature on.

Microsoft already has rules like this for custom agents built in Copilot Studio. Its billing page says that under prepaid capacity, custom agents are disabled when a company reaches 125% of what it bought. Admins can set monthly limits for each agent in the Power Platform admin center. That's a useful brake, but an agent your team relies on can also stop mid-month if no one is watching.

Lane Shelton of Directions on Microsoft made a related point about Microsoft's top bundle, E7. As quoted by UC Today, he wrote that the $99 seat price is "only the down payment" on running E7 at scale, because meters like Copilot Studio credits aren't included.

Where Microsoft has a point

To be fair, metered billing isn't a trick. It lets a company try the agent features without buying a bigger plan for everyone. The limit can be changed. Existing subscriptions are untouched. And Nadella's argument on the call is reasonable: when agents do higher-value work, paying for what they actually do ties the cost to the value. Microsoft is also running promotions through Dec. 31, 2026 on Copilot Business through resellers, which may make this a good time to buy if you've already decided you want it.

The issue isn't the meter. It's buying without knowing it's there.

What to do this month

1. Ask your IT provider one question: "Are we buying any new Copilot Business licenses after Dec. 1, and will usage-based billing be on?" If you buy through a reseller, the answer is likely yes.
2. Decide who needs the metered features. Most people who use Copilot to draft emails and summarize meetings may not need agent features like Cowork. Set the limit by group, not one number for everyone.
3. Set a company-wide monthly alert before the first bill, and name the person who reads it.
4. If you run custom agents in Copilot Studio, set a monthly limit per agent and know what happens at 125%. An order-entry or AP agent that shuts off on the 20th is its own kind of problem.
5. Measure the work, not the usage. Credits used tells you cost. It doesn't tell you whether orders got entered faster. Track minutes per item before and after, like we describe in our guide to measuring the ROI of office automation.

None of this means you should avoid Copilot. For everyday writing and summarizing, a general tool can be the right choice, as we cover in ChatGPT vs. custom AI. It means the AI line on your budget is turning into a meter, and meters need someone watching them.
