In Short: Copilot Business Now Ships With the Meter Running

Microsoft is switching on Copilot Business usage-based billing by default. New Microsoft 365 Copilot Business licences will arrive with pay-as-you-go billing already configured, the Azure plumbing created for you, and a default spending limit of 4,000 Copilot Credits per user per month. Microsoft's Partner Center announcement, dated 1 October 2026, says the point is to give customers access to credit-billed experiences "including Copilot Cowork, Work IQ APIs, and GitHub Copilot Harness, with less billing setup".

That is good news for adoption and a real risk for budgets. Until now, a small business had to set up usage-based billing deliberately before any credit-billed feature could run. From the rollout date, a new licence does that setup for you. This post covers the dates, what is in scope, what the default limit means in money, and the settings I would check on day one. For the wider pricing model, read our explainer on Microsoft Copilot pricing, licences and Copilot Credits.

The Dates: 19 October Direct, 1 December Through CSP

There are two channels and two dates, and only one of them is on a Microsoft page I could open.

CSP purchases: 1 December 2026. Microsoft's Partner Center October 2026 announcements say usage-based billing "will be enabled by default for new Microsoft 365 Copilot Business licenses purchased in Cloud Solution Provider (CSP)" from 1 December, "previously communicated as November 2, 2026". Partner Center sandbox environments for testing are due on 2 November.
Direct purchases: 19 October 2026. This date comes from Message Center notice MC1476200. Message Center sits behind the admin sign-in, so I am relying on third-party sites that reproduce the notice word for word, and they agree on 19 October. If you buy direct, open MC1476200 in your own admin center and confirm the date there.

As I write on 8 October, the change is announced but has not started rolling out in either channel.

It will not reach everyone at once. Microsoft says it will "initially not be available in Australia, Belgium, Brazil, France, Germany, India, Italy, Korea, the Netherlands, Poland, and Spain". The UK, the US and South Africa are not on that list, so most of our clients are in the first wave.

What Is Actually Switched On

The change applies to new purchases of Microsoft 365 Copilot Business, "including standalone offers and bundles". Copilot Business is the add-on for organisations of up to 300 users. On 8 October 2026 Microsoft's business pricing page listed it at $21 per user per month, with a promotional $18.

According to Partner Center, a new licence now includes "the Azure subscription setup needed for usage-based billing", with pay-as-you-go as the default billing method. The MC1476200 text, as reproduced by third parties, says Microsoft will "automatically create the required Azure resources and apply a spending policy", and that existing subscription benefits and payment terms do not change. One reproduction also says buying extra seats can bring usage-based billing to the tenant. I could not confirm that on a Microsoft page, so read your own notice before you add seats.

Credits pay for work you hand off rather than work you do alongside Copilot. Microsoft Learn lists the services currently managed through usage-based billing as Cowork, advanced work in SharePoint and OneDrive, the Work IQ API, Copilot Managed Runtime and Teams Phone Agent. The everyday Copilot features in Word, Excel, Outlook and Teams stay on the per-user licence. If Cowork is new to you, we set out the case in what Copilot Cowork means for enterprise AI, and our guide to the new Copilot with Home, Code and Autopilot covers the experiences that are on their way to credits.

What 4,000 Credits Means in Money

The default limit is "4,000 Copilot Credits per user per month, which can be adjusted by admins". Microsoft's own example: a customer with 100 Copilot Business users "could consume up to 400,000 Copilot Credits per month under the default spending limit, with UBB charges based on actual usage".

It is a ceiling, not a bill. Nobody pays for 4,000 credits up front, and most users will consume far fewer. But it helps to translate the ceiling into money. Microsoft's Learn page on the Copilot Credit pre-purchase plan works its example at a pay-as-you-go rate of $0.01 per credit. At that rate, 4,000 credits is $40 per user per month, which is nearly double the $21 list price of the licence itself. For 100 users, the default ceiling is $4,000 a month.

The number of credits a task uses depends on the model, runtime, context and tools involved, so there is no fixed cost per task. Microsoft publishes a Copilot Credit estimator for Cowork. If you are modelling agents more broadly, our breakdown of the real cost of AI agents is a useful companion.

The Settings to Check on Day One

Everything below lives in the Microsoft 365 admin center under Copilot, then Cost management. Global administrators and Billing administrators can change billing methods. AI administrators and License administrators can edit spending policies, limits and alerts but cannot create policies. Reader roles such as AI Reader can see the dashboards without changing anything, which suits finance.

Policy limit. Decide whether the default policy should have a monthly limit for the organisation as a whole. Learn notes that activating the default policy sets the tenant-level limit for all users, and each extra policy has its own independent limit.
Per-user limit. Set one. Microsoft's own guidance is to use it "to prevent runaway spending of Copilot Credits by one individual user". When users hit a limit, they lose access to credit-billed services until credits reset on the first of the month.
Alerts. Add admin alerts at a credit or percentage threshold, and user notifications so people know they are approaching their limit. Alert emails repeat daily once the threshold is reached.
Auto-apply new services. This is on by default, so the policy will cover future Copilot services and agents you have not reviewed yet. Turn it off if you want to approve each new service first.
Scope. The default setup "targets your entire organization and all users". Narrow it to security groups with a real use case.
Model profiles. For Cowork, you can limit which models a policy can use. Learn says this is currently available only for Cowork.

Credit requests let users ask for access or a higher limit, so a tight starting point does not block anyone permanently.

How I Would Handle It

For a new Copilot Business tenant, I would start with every user on a modest per-user limit, put Cowork and the other credit-billed services behind one pilot group, turn off Auto-apply new services, and review consumption weekly for the first month. Then raise limits for the people whose usage is producing results. That is the same pilot-with-a-cap approach we recommend in our Microsoft Copilot licensing guide, just with the meter arriving pre-installed.

Cost is only half of the readiness work. Credit-billed experiences like Cowork can reach a lot of content in one go, so it is worth tidying what Copilot can see at the same time. Our guide to keeping stale and sensitive content away from Copilot covers the Purview side.

Where Solv Systems Comes In

We help small and mid-sized organisations set up Copilot so the first invoice holds no surprises: spending policies and user limits sized from real usage, a pilot group with a clear use case, and agents built where the numbers justify them. Read more about our AI automation and agent services.

Frequently asked

New Copilot Business licences come with usage-based billing switched on by default. Microsoft says pay-as-you-go will be the default billing configuration, the Azure setup needed for billing is included, and a default spending limit of 4,000 Copilot Credits per user per month applies. This opens experiences billed in credits, such as Copilot Cowork, the Work IQ APIs and the GitHub Copilot harness, without separate billing setup.

Microsoft's Partner Center announcement of 1 October 2026 gives 1 December 2026 for new licences bought through CSP, moved from 2 November. Message Center notice MC1476200, as reproduced by third-party sites, gives 19 October 2026 for direct purchases from Microsoft. Check MC1476200 in your own admin center for the date that applies to you.

The change applies to new purchases. The MC1476200 text, as reproduced by third parties, says existing Copilot Business subscription benefits and payment terms do not change. One reproduction also says that buying additional seats can bring usage-based billing to the tenant, so check the exact wording in your Message Center before adding licences.

It is a default spending limit, not an allowance you pay for in advance. Charges are based on actual usage. Microsoft's own example is a customer with 100 Copilot Business users, who could consume up to 400,000 Copilot Credits a month under the default limit. Admins can adjust it.

Microsoft says the change will initially not be available in Australia, Belgium, Brazil, France, Germany, India, Italy, Korea, the Netherlands, Poland and Spain, and that it will share more as availability expands. The UK, the US and South Africa are not on that list.

Open Copilot then Cost management in the Microsoft 365 admin center, review the default spending policy, set a policy-level and per-user monthly limit that matches your budget, add alerts, decide whether Auto-apply new services should stay on, and scope access to the groups that have a real use case.
