The short version
- Microsoft moved the start of default usage-based billing for new Microsoft 365 Copilot Business subscriptions bought through CSP. It was set for December 1, 2026. Rollout now begins during Microsoft's FY27 Q3, which runs January to March 2027.
- Microsoft hasn't named the exact date yet. It says it will announce one in advance.
- Once rollout starts, new Copilot Business purchases, including bundles, turn on usage-based billing by default. A new purchase also turns it on for the Copilot Business licenses already in that tenant.
- The default spending limit is 4,000 Copilot Credits per user per month. Admins can change it, down to Microsoft's minimum of 2,000.
- Use the extra time to decide who gets the usage-based features, set limits that fit your budget, and name the person who reviews usage each month.
What did Microsoft change?
On November 3, 2026, Microsoft updated its Partner Center announcement on usage-based billing for Copilot Business. The default-on date of December 1, 2026 is gone. Rollout is now planned for Microsoft's FY27 Q3, January to March 2027, and Microsoft says it's "adjusting the effective dates to give you extra time to prepare."
The timing moved. The billing model is still coming.
What's usage-based billing for Copilot Business?
The Copilot Business license is a per-user seat that covers everyday Copilot features. Some newer AI experiences bill separately, by usage, in Copilot Credits. Microsoft names Copilot Cowork, Work IQ APIs and GitHub Copilot Harness as examples. Our October 2026 licensing update covers what a Cowork task can cost.
When usage-based billing is on by default, Microsoft creates the Azure resources it needs, sets pay-as-you-go as the billing method, and applies a default spending limit. That removes setup work. It also means usage can start billing without anyone deciding a budget first.
Who does it apply to?
New purchases of Microsoft 365 Copilot Business in CSP, both the standalone license and the bundles. Copilot Business is the version for organizations with up to 300 users.
One detail is easy to miss. Microsoft says a new purchase also turns on usage-based billing by default for the existing Copilot Business licenses in the same tenant. If you already own Copilot Business and add seats after rollout begins, plan for the whole tenant to move to the new setup.
What does the default limit mean in dollars?
The default is 4,000 Copilot Credits per user per month, applied to every user in the organization. Microsoft's example: a customer with 100 Copilot Business users could consume up to 400,000 Copilot Credits a month under the default.
Microsoft's own Copilot Credit examples assume $0.01 per credit on pay-as-you-go. At that rate the default ceiling is $40 per user per month, or $4,000 a month for 100 users. That's the ceiling. You're billed for what people use. Still, a limit you set on purpose beats one you inherit by default.
Can you turn it off?
Admins can adjust spending limits in Partner Center and in the Cost management dashboard in the Microsoft 365 admin center. That's also where you set limits by user, configure policy alerts and turn on user-level threshold notifications.
Microsoft notes that disabling usage-based billing might limit access to some AI experiences. For most organizations the better lever is a lower limit for most users and a higher one for a pilot group. Microsoft's minimum per user is 2,000 credits a month.
What should you do with the extra time?
- Decide who needs the usage-based features. Many users only need the seat. Start a small pilot group on Cowork or agents.
- Set limits before rollout. The default is 4,000 credits per user per month and the minimum is 2,000. Pick a number your budget can absorb. A user who hits the limit loses access to those features until credits reset on the first of the month.
- Turn on alerts and name an owner. Someone on your team should review consumption every month and know when a user hits a threshold.
- Time your seat purchases. If you're adding Copilot Business seats early next year, remember that a purchase after rollout moves the whole tenant to the new default.
- Hold off on prepaying. Get a few months of pay-as-you-go data before you commit to a pre-purchase plan. Our guide to Copilot Credit P3 vs Microsoft Agent P3 covers how to size one.
Plan your Copilot Business budget now
Copilot cost now has two parts: the seat and the credits. Our licensing team maps each user to the right Copilot license, models a realistic credit budget for your pilot group, and sets the spending policies before the default arrives. A Microsoft licensing assessment is a good place to start.
