Your next Microsoft 365 Copilot licence arrives with the meter already running

On July 1 Microsoft bundled Copilot into Microsoft 365 Business Standard and Premium and told every small business to pick a plan. That was the visible change. There is a quieter one arriving now, and it does not change the seat price at all — which is exactly why it is easy to miss. If you are still deciding whether to adopt it, our Microsoft 365 Copilot guide for SMBs covers what it does and what it costs.

Start here: if you buy a new Microsoft 365 Copilot Business licence on or after October 19, 2026 directly from Microsoft, or on or after December 1, 2026 through a reseller (Microsoft moved this date from November 2 on October 1), that licence comes with usage-based billing already switched on. You did not choose it. Nobody ticks a box. The meter is simply there, attached to an Azure subscription Microsoft creates for you, with a monthly spending limit that you also did not set.

That is not a price rise. It is something more annoying: a fixed bill turning into a fixed bill plus a variable one, by default, for the smallest businesses. The change is small enough to be handled by one person in twenty minutes — as long as that person reads the notice before the purchase, not after the invoice.

What actually changed, in one paragraph

Microsoft 365 Copilot Business is the add-on for organisations of up to 300 users, sold on top of Business Basic, Standard or Premium. Until now, the AI features that run on its own meter — Copilot Cowork, the Work IQ APIs, GitHub Copilot Harness — stayed locked until an administrator deliberately connected an Azure subscription and wrote a spending policy. Nobody could spend a cent by accident, because nobody could spend anything at all.

From the two dates above, that gate is open when you buy a new licence. Microsoft's partner announcement of September 16, 2026 says pay-as-you-go is now the default billing configuration for eligible new Copilot Business purchases, and that Microsoft will create the required Azure resources and apply a spending policy automatically. In plain terms: the switch that used to be off ships on.

Existing licences are not affected. If you already own Copilot Business, nothing changes for you on those two dates — the gate stays shut until someone opens it. The announcement only covers new standalone and bundled purchases.

What a Copilot Credit actually costs

Microsoft charges AI consumption in Copilot Credits, and on pay-as-you-go a credit costs one cent. That sounds harmless until you remember what a credit buys. A credit is not a message. It is metered work: the model used, how long the agent ran, how much context it pulled in, how many steps it took. Cowork-style agents that run for minutes at a time are the expensive kind, and they are exactly the kind the default flip unlocks.

Two payment routes exist, and they behave differently at the end of the year:

Prepaid credits are always consumed first, so the pay-as-you-go meter only starts after they run dry — which is the trap with intermittent use. A small business buys a year of credits for the discount, uses a fifth of them, and watches the rest expire while the meter quietly leans on the card.

For a two-person or ten-person business the numbers are small either way, in absolute terms. That is the honest answer. Ten dollars a month is not going to break anyone. But ten dollars per user per month across fifteen users, added to a licence you bought expecting a fixed price, is the kind of line item that only gets noticed in February when somebody finally reads a bank statement.

The two dates, and why they differ

Microsoft did not turn this on everywhere at once. The change rolls out in two waves, and the wave you are in depends on how you buy Microsoft, not on the size of your business.

If you buy directly from Microsoft — through the Microsoft website or the Microsoft 365 admin centre — the change applies to eligible new purchases from October 19, 2026 (a date from Microsoft's Message Center notice as relayed by partners; the public pages we could read give only the CSP date). That is the wave most owner-operators fall into, because buying a licence directly with a card is what a small business without an IT partner usually does.

If you buy through a Cloud Solution Provider — a reseller, an IT provider, the person who set up your tenant — the change applies from December 1, 2026. Microsoft first announced November 2 and moved the date on October 1, 2026 (Partner Center announcements, October 2026), because the reseller gets the notice through Partner Center and Microsoft gives partners room to explain it to their customers first.

Microsoft also says the change will initially not be available in Australia, Belgium, Brazil, France, Germany, India, Italy, Korea, the Netherlands, Poland and Spain. If your tenant is in one of those markets, the default flip does not apply yet.

The practical consequence of the split: if you are two weeks from signing a new Copilot Business licence through your reseller, the default is still off when you sign and on if you wait until mid-November. That is not a reason to rush. It is a reason to know which date is yours.

The check to run before you buy

This is not a reason to avoid Copilot Business. It is a reason to spend twenty minutes in the admin centre before you press buy, rather than discovering the setup afterwards. Everything below lives in one place: the Microsoft 365 admin centre, under Copilot, then Cost management.

1. Set your own monthly limit. The default policy arrives with a preset spending limit. Microsoft's Partner Center notice of October 1, 2026 sets the default at 4,000 Copilot Credits per user per month, adjustable by admins (about $40 if the $0.01 rate holds); earlier reseller write-ups that said $10 are superseded. Check the number that is actually on your policy. If it is not a figure your budget can absorb, change it. A limit of zero is legitimate: it keeps the experience off while leaving the licence in place.
2. Decide about "auto-apply new services". This setting is on by default, and it does exactly what it says: any future Microsoft agent or service that becomes eligible for metered billing joins your spending policy automatically, without anyone approving it. If you want to see each new line item before it can spend, turn it off. This is the single most-skipped setting in the whole dashboard.
3. Set a threshold alert below the cap. Alerts exist specifically so the first warning is not the invoice. Put the alert at a level you would still consider cheap, not one you would consider painful.
4. Count who can reach it. Cowork-style agents are available to licensed users, and people can install them themselves. If twenty people have a licence and two people will ever use an agent, the per-user limit is the lever that matters, not the organisation-wide one.
5. Write down the date. If you are buying within a month of October 19 (direct) or December 1 (CSP), the default posture changed under your feet. Put the two dates next to your renewal date so the next purchase is a decision instead of a surprise.

None of this needs a consultant. It needs one person with admin rights, the Cost management screen open, and fifteen minutes.

A fixed price that becomes a default meter is not a price rise. It is a decision that got made for you while nobody was looking at the screen.

Why defaults matter more than prices

Who can safely ignore this

Plenty of businesses can read this and move on, and it is worth saying so plainly rather than manufacturing urgency.

If you do not own Microsoft 365 Copilot Business and have no plan to buy it, this affects you in no way. Copilot Chat — the basic assistant included with eligible Microsoft 365 plans — is a different thing, at no extra cost, and is not what this change touches. If your business runs entirely on Google Workspace, or on no suite at all, the only takeaway is the general one: subscription vendors are steadily converting flat AI add-ons into metered ones, and "flat price" is a promise with an expiry date.

If you already hold Copilot Business licences, the announcement does not reach you. Microsoft's notice covers new purchases only, and it says nothing about retrofitting the default onto existing seats. Your meter is still off until someone turns it on — which is its own small piece of good news, and also a reminder that you may want to check whether anyone already did.

The businesses that should act are narrower than the headline suggests: those buying a new Copilot Business licence, or renewing into one, in the next six to eight weeks. For everyone else this is background knowledge and a diary note.

Frequently asked questions

Is this a Microsoft 365 price increase?

No. The Copilot Business seat price is unchanged, and Microsoft's partner notice is about billing configuration, not rates. What changes is that a new licence arrives with usage-based billing already enabled, so a variable charge can now appear next to the fixed one. Existing licences keep whatever configuration they have.

How much can the meter actually cost?

On pay-as-you-go, Copilot Credits cost $0.01 each, and consumption is capped by the monthly limit on your spending policy. Microsoft's Partner Center notice of October 1, 2026 sets the default limit at 4,000 Copilot Credits per user per month, which admins can change; verify the real figure on your own policy. Prepaid credits under a pre-purchase plan use up first and expire after a year.

Which features sit behind the meter?

Microsoft names Copilot Cowork, the Work IQ APIs and GitHub Copilot Harness as the initial eligible experiences, and says more will be added. Everyday Copilot work in Word, Excel, Outlook and Teams stays covered by the fixed licence and does not consume credits.

Do I need to buy an Azure subscription?

No. Microsoft creates the required Azure resources and attaches the spending policy as part of the new purchase. That is the point of the change — less setup — and also why it happens without you noticing. Your job is to review the limits it comes with, in Copilot > Cost management in the Microsoft 365 admin centre.

Can I simply turn usage-based billing off?

Yes, and Microsoft documents the consequence: disabling usage-based billing also removes access to the experiences that need it. If Cowork-style agents were the reason you wanted Copilot Business, switching the meter off removes the capability you paid for. The middle path is the usual one — leave it on with a limit you chose.
