Which purchases does the December 1 change cover?
Microsoft says usage-based billing will be enabled by default for eligible new Microsoft 365 Copilot Business purchases through the Cloud Solution Provider (CSP) channel from December 1, 2026. The announcement covers standalone offers and bundles, with a default spending limit of 4,000 Copilot Credits per user per month, adjustable by administrators.
The change begins rolling out in supported markets. Charges depend on actual usage of eligible services. Enabling billing does not itself mean that credits have been consumed.

Before placing an order, ask your reseller how the announced change applies to the purchase and to your existing tenant configuration. Confirm the treatment of new subscriptions, renewals and seat adjustments separately.
Does 4,000 credits mean an automatic US$40 charge?
No. The charge depends on credits consumed and the pricing arrangements that apply. Microsoft's Copilot Cowork pricing announcement publishes a PayGo rate of US$0.01 per Copilot Credit. This is a stated Cowork rate, not a universal price or spending ceiling for every Microsoft service. At that rate, consuming 4,000 credits would cost US$40. The examples below show the arithmetic if each listed user consumed 4,000 credits in the month.

| Users in the example | Credits consumed per user | Illustrative usage charge |
|---|---|---|
| 10 | 4,000 | US$400 |
| 25 | 4,000 | US$1,000 |
| 50 | 4,000 | US$2,000 |
Calculation: users × 4,000 credits × US$0.01. These examples are calculations, not forecasts of consumption, invoices or a guaranteed maximum for all spending in a tenant. They exclude subscription charges, taxes and other services. Actual charges depend on consumption, contract pricing, prepaid credits and the policies that apply.
Microsoft documents separate limits for additional spending policies. Review the full configuration before treating any one displayed limit as the ceiling for the organization.

Can every spending policy be set to zero?
Do not assume a universal zero-credit option. Microsoft's management documentation describes controls for service access, user and group scope, spending limits and notifications. The documented spending-policy flow currently specifies a minimum of 2,000 credits per user per month. Confirm the options and requirements shown in your tenant.
Also review whether a policy automatically includes newly supported services. Microsoft documents this setting as enabled by default. An administrator can review the setting and determine whether future services should be added automatically.

A separate December 1 change to the base-subscription requirement
Microsoft also announced new Copilot and Copilot Business offers for December 1, 2026 without a qualifying Microsoft 365 base-subscription purchase prerequisite. Current add-on offers still have their present eligibility requirements. Available features continue to depend on the Microsoft apps and services the user is licensed to use.
Record the exact offer and purchase date. Ask the provider whether an order uses the current add-on, a bundle or a new December offer before applying a base-license assumption.

A purchase review for a professional-service firm
Use the following questions to prepare the discussion with the person who administers your Microsoft environment.
- Purchase: What exactly are we buying, through which channel, and on which billing account?
- Scope: Which users, groups, subscriptions and services will the change affect?
- Budget: What level of consumption is approved, and which available settings will implement that decision?
- Ownership: Who reviews usage, receives alerts and authorizes a change to the limit?
- Evidence: Where will we keep the purchase details, approved limits, configuration record and next review date?
Keep the agreed answers beside the subscription record. A written budget decision and a configured vendor policy are separate tasks; confirm that both have been completed.
