Copilot usage billing moved to early 2027. Set your spending limit before you buy.

Microsoft now says new Microsoft 365 Copilot Business purchases through resellers will switch on usage-based billing by default in January to March 2027, not December 1. The default is 4,000 Copilot Credits per user per month, it applies across the tenant, and it can be capped at zero but not turned off.

Microsoft has moved the date when new Microsoft 365 Copilot Business purchases through resellers switch on usage-based billing by default. In a Partner Center announcement dated November 3, 2026, it said the change now arrives during its fiscal 2027 third quarter, January to March 2027, instead of December 1, 2026.

The date moved. The design did not. When it lands, a new Copilot Business purchase through the Cloud Solution Provider (CSP) program will set up usage billing for the whole tenant, with a default limit of 4,000 Copilot Credits per user per month. If you buy Microsoft 365 through a reseller, the useful step this quarter is to agree, in writing, what that limit should be before anyone adds a seat.

What happened

Microsoft’s November 3 update says usage-based billing “is now enabled by default for new Microsoft 365 Copilot Business subscriptions purchased in Cloud Solution Provider (CSP) during Microsoft’s FY27 Q3 (January-March 2027), instead of December 1, 2026, as previously announced.” Microsoft says it heard partner feedback and wanted to give partners extra time to prepare. The same update moved a Partner Center sandbox date that had been set for November 2. Microsoft says it will announce a new sandbox date, and that sandbox testing will be available for at least 30 days before general availability.

The rest of the announcement is unchanged in substance:

  • Scope. New purchases of Microsoft 365 Copilot Business licenses in CSP, including standalone offers and bundles.
  • Whole tenant. “New purchases enable usage-based billing by default for existing Microsoft 365 Copilot Business licenses in the tenant.” One new purchase turns it on for the Copilot Business users you already have.
  • Default limit. 4,000 Copilot Credits per user per month, which admins can adjust. Microsoft’s own example: a customer with 100 Copilot Business users could consume up to 400,000 credits a month under the default.
  • Billing. Pay-as-you-go is the default configuration. Microsoft names Copilot Cowork, Work IQ APIs and GitHub Copilot Harness as eligible usage-based experiences.
  • Markets. The updated timelines apply in all markets, including several, such as Australia, Brazil, France, Germany and India, where Microsoft had not expected these capabilities to be available at first.

How the switch works

Microsoft’s Partner Center documentation for the feature fills in detail that matters to a buyer. It covers Copilot Business only. Microsoft 365 Copilot for enterprise is out of scope, and so are education, nonprofit and GCC low tenants. The page also says some of what it describes is not yet released and that API details may change before general availability.

  • No separate opt-in. The reseller uses the same add-to-cart flow as today. Partner Center creates the Azure resources and a default spending policy at checkout.
  • What triggers it. A new subscription purchase, adding seats to an existing Copilot Business subscription through the Partner Center portal, or a Copilot trial converting to a paid license.
  • Existing policies win. Partner Center creates the default policy only if the tenant has no spending or billing policy from any channel or partner.
  • It can be capped, not removed. “Usage-based billing can’t be fully turned off once configured.” Partners set the spending limit to zero, which stops further spend while leaving the policy in place. Microsoft also warns that disabling usage-based billing might limit access to some AI experiences.
  • Two limits. When a partner creates a policy by hand, the documented defaults are 1,200,000 credits for the tenant and 4,000 per user.

A worked example

Take an illustrative ten-person firm that buys Copilot Business for all ten staff through its reseller in February 2027. These are example inputs, not a real customer.

  • Seat cost. Microsoft’s public pricing page lists the Copilot Business add-on at $21.00 per user per month, shown as $18.00 under a promotion that runs from July 1 to December 31, 2026, applies to the first year only and requires an annual commitment. A February 2027 purchase falls after that window, so budget at list unless your reseller confirms otherwise, and note that a reseller’s price can differ from Microsoft’s own page: 10 × $21.00 = $210 a month, or $2,520 a year.
  • Usage ceiling under the default. 10 users × 4,000 credits = 40,000 Copilot Credits a month that the firm could consume before the limit stops it. That is a ceiling, not a forecast. Actual charges depend on actual usage.
  • The dollar value of that ceiling. We have not found a per-credit price on a Microsoft page we could verify, so we are not putting a dollar figure on 40,000 credits. Ask your reseller to show the per-credit rate on the quote.

The limitation is the point: the seat price is fixed and published, the usage side is not, and the default is set by Microsoft, not by you.

What it means for owners and CFOs

For a small business, this turns Copilot from a fixed per-seat line into a fixed line plus a metered one. The metered part starts with a ceiling you did not choose, applies to staff you licensed before the change, and cannot be switched off afterward, only capped. None of that is a reason to avoid Copilot. It is a reason to treat the spending limit as a purchasing decision, like a seat count.

The other change on the calendar is earlier. Microsoft’s October Partner Center announcements say that from December 1, 2026, new Microsoft 365 Copilot and Copilot Business offers can be bought without a qualifying Microsoft 365 base subscription, and the current add-on offers reach end of sale in CSP that day. Existing customers can keep renewing them. Expect your reseller’s quote to change names around then, so check that the line items match what you agreed.

What to do this week

  1. Ask your reseller one written question. “If we buy or add Copilot Business seats after usage billing turns on by default, what spending limit will you set, per user and for the tenant, and will you set it before checkout?”
  2. Pick a number. Zero is a valid answer if you do not plan to use metered features yet. If you do, set a per-user limit you can explain and a tenant limit you can afford in a bad month.
  3. Name an owner. Someone should check the usage view in Partner Center or the Microsoft 365 admin center monthly, and the reseller should tell you if it changes a limit.
  4. Check your renewal date. If your Microsoft 365 renewal falls between now and March 2027, read Your Microsoft 365 renewal price, line by line first. It covers the July 1 list prices with 10- and 25-seat examples.

What to watch next

  • A firm date. “January to March 2027” is a plan. Microsoft has said it will announce the sandbox date in advance. Watch the Partner Center announcements page for the general availability date.
  • A published per-credit price. Until it is on a Microsoft page, any dollar ceiling on the 4,000-credit default is an estimate.
  • December 1 offer changes. The base-subscription requirement goes away for new offers that day. Confirm your quote uses the offer and promotion you expect.
