Copilot Business metering from Dec 1: up to $8,000/month at 200 seats

Microsoft will switch on usage-based billing by default when customers buy new Microsoft 365 Copilot Business licenses through its Cloud Solution Provider (CSP) program, starting December 1, 2026. It updated its Partner Center notice on October 14, moving the start from November 2. New licenses come with a default spending limit of 4,000 Copilot Credits per user per month, and the metered charges appear on the invoice separately from the seat fee.

The same week, Microsoft said that from December 1 both Copilot plans can be bought without a Microsoft 365 base subscription, at the same price. From October 16, the current plans carry "(add-on)" in their names.

For a small or midsize company, the seat price is no longer the whole Copilot cost. Agent work in Copilot Cowork, calls to the Work IQ APIs and the GitHub Copilot Harness are now metered, and once an admin turns those agents on, the default limits let that meter run well past the seat price before anything stops it.

What the default cap allows

Witivio, TIKR and Quisitive all give the pay-as-you-go list price as $0.01 per credit. Witivio says the charge lands on an Azure subscription, billed each month after use. On that price, the 4,000-credit default works out to $40 per user per month. Copilot Business launched at $21 per user per month list, Office Watch reported, so the default metered ceiling is about 1.9 times the launch seat price.

These figures are ceilings, not forecasts. A user who runs no metered agents costs nothing extra. But nothing in the default setup stops a busy team from reaching the cap every month.

Microsoft's Partner Center guide also sets a default tenant limit of 1,200,000 credits. That is exactly 300 users times 4,000 credits, and Copilot Business stops at 300 seats, according to Office Watch and Schneider IT Management. So under the defaults, at any size Copilot Business allows, the tenant limit does not cut in before the per-user limits do. A company with 2,000 staff cannot put them all on Copilot Business; above 300 seats, Microsoft points customers to Microsoft 365 Copilot, which the guide says is out of scope for this change.

What 4,000 credits buys

Cowork has no fixed price per task, Witivio says. Quisitive puts a medium task, such as building a project board from email, at about 400 to 700 credits, and a light task such as message triage at 100 to 300. By those ranges, the default limit covers roughly five to 10 medium Cowork tasks per user per month. A user who hits the limit loses access to the metered agents until the first of the next month, unless more credits are granted, Witivio says.

Credits are cheaper in bulk. Witivio lists Copilot Studio capacity packs at $200 a month for 25,000 credits, or $0.008 a credit, and a pre-purchase plan with discounts from 5% to 20%. Prepaid credits are used before pay-as-you-go, Schneider notes.

Who it applies to

The default applies to new purchases: a new subscription, seats added in the Partner Center portal, and a trial that converts to a paid license. Microsoft says nothing switches on without a purchase event, so an existing subscription changes only when seats are added that way. For a customer with no Azure account, the purchase creates an Azure subscription and resource group to carry the charges.

Microsoft excludes 11 markets at launch: Australia, Belgium, Brazil, France, Germany and India, plus Italy, Korea, the Netherlands, Poland and Spain. Education, nonprofit and GCC Low government tenants are out of scope. Witivio, citing Microsoft message MC1476200, says the same default reaches direct purchases from Microsoft on October 19, ahead of the CSP date.

The Partner Center guide also says usage-based billing "can't be fully turned off once configured." The way to stop spend is to set the limit to zero or delete the spending policy, and the tenant still pays for usage before that.

The name change

Message center post MC1508148 renames Microsoft 365 Copilot and Copilot Business to "Microsoft 365 Copilot (add-on)" and "Microsoft 365 Copilot Business (add-on)" from October 16. CSP partners stop selling the add-on versions on December 1. That is not end of life: existing customers can renew and change seat counts. The new standalone versions get new product and SKU IDs, which Microsoft's Partner Center notice says will be shared before its November 1 price list preview.

Pricing, rights and renewals on existing subscriptions do not change. Scripts that find licenses by product name may break, though, which is why the post asked admins to switch them to product or SKU IDs by October 16.

Microsoft CEO Satya Nadella has described the direction as moving past pure per-seat pricing to "per seat plus consumption," TIKR reports.
