Copilot Business Usage-Based Billing Turns On by Default December 1, 2026: What CSP Customers Need to Know About the 4,000-Credit Cap

The Change: Usage-Based Billing Becomes the Default for CSP Copilot Business

Starting December 1, 2026, usage-based billing will be enabled by default for new Microsoft 365 Copilot Business licenses purchased through the Cloud Solution Provider (CSP) program. That includes both standalone offers and bundles.

The date has reportedly moved. Microsoft had earlier planned to make the default take effect on November 2, then pushed it back to December 1.

This reverses how things worked before. Previously, an administrator had to deliberately activate usage-based billing and set up a spending policy before anyone in the organization could use Copilot Cowork. Under the new default, that opt-in step is no longer required for new CSP licenses.

Which Products and Scenarios Are Affected

The change covers Microsoft 365 Copilot Business and the Business suites that bundle Copilot:

• Microsoft 365 Copilot Business
• Microsoft 365 Business Premium with Copilot
• Microsoft 365 Business Standard with Copilot
• Microsoft 365 Business Basic with Copilot

New purchases are not the only trigger. Usage-based billing will also be enabled when customers:

• Add Copilot Business seats to an existing subscription
• Upgrade to a Copilot Business SKU
• Receive a new subscription through a partner-to-partner transfer

The 4,000-Credit Default Spending Cap

The default spending policy is capped at 4,000 Copilot Credits per user per month, which works out to approximately $40 USD per user per month.

The cap works as a firm ceiling. Usage can go above it only if an administrator changes the policy. Organizations that leave the default alone will have per-user consumption limited to that amount.

How Billing Works Behind the Scenes

Microsoft will automatically set up an Azure subscription configured with the default spending policy, so customers don't need to provision the billing setup themselves.

Billing is pay-as-you-go, meaning customers are charged for their actual usage rather than a fixed amount. The 4,000-credit cap sets the most that can be spent per user unless an administrator raises it.

What Usage-Based Billing Pays For

Usage-based billing covers a specific set of eligible experiences. These include:

• Copilot Cowork, which until now required an administrator to switch on usage-based billing and a spending policy before anyone could use it
• Work IQ APIs
• GitHub Copilot Harness

Key Dates for CSP Partners and Customers

• November 2, 2026: Partner Center sandbox environments open so partners can test the usage-based billing flow.
• December 1, 2026: Usage-based billing turns on by default for new CSP Copilot Business licenses.
• December 31, 2026: Last day to start Copilot in 30 trials.

What CSP Customers and Partners Should Do Now

With the default arriving December 1, here is where partners and customers can focus:

• Test in the sandbox. Partners can use the Partner Center sandbox environments, which open November 2, to try out the usage-based billing flow before the default takes effect.
• Review the default cap. Administrators should decide whether the 4,000-credit (about $40) per-user monthly limit suits their organization. Usage can exceed it only if an administrator changes the policy.
• Plan for subscription changes. Customers who add seats, upgrade to a Copilot Business SKU, or move subscriptions through a partner-to-partner transfer should expect usage-based billing to be enabled.
• Note the trial deadline. Organizations interested in Copilot in 30 trials need to start them by December 31, 2026.
