EPC Group Publishes a 12-Step Spending-Policy Playbook as Microsoft 365 Copilot Usage-Based Billing Turns On by Default for New Copilot Business Purchases

HOUSTON, October 7, 2026 — EPC Group, a Houston-based Microsoft consulting firm founded in 1997, today published an updated 12-step spending-policy playbook for IT and finance teams ahead of a change Microsoft is making to how Microsoft 365 Copilot is billed: starting October 19, 2026, for direct Microsoft purchases, and December 1, 2026, for purchases through the Cloud Solution Provider channel, new Microsoft 365 Copilot Business subscriptions will arrive with usage-based billing switched on by default, an Azure billing resource created automatically, and a default spending policy applied. The playbook is at the Copilot usage-based billing spending-policy playbook.

What Microsoft has published

Microsoft announced the change in Message Center post MC1476200 on September 21, 2026. On October 1, 2026, Microsoft's Partner Center announcements moved the Cloud Solution Provider effective date from November 2 to December 1, 2026, and set the default spending limit at 4,000 Copilot Credits per user per month, adjustable by administrators. Microsoft's example: a customer with 100 Microsoft 365 Copilot Business users could consume up to 400,000 Copilot Credits per month under the default limit, with charges based on actual usage. The change applies to new purchases of Copilot Business licenses, including standalone offers and bundles; existing subscriptions do not change. Microsoft states the CSP rollout will initially not be available in Australia, Belgium, Brazil, France, Germany, India, Italy, Korea, the Netherlands, Poland and Spain.

Copilot Credits are the currency for the usage-billed experiences Microsoft manages in the Microsoft 365 admin center. Microsoft's documentation lists Cowork, Advanced work in SharePoint, Advanced work in OneDrive, the Work IQ API for custom apps and agents, the Copilot Managed Runtime and Teams Phone Agent, and states that more agents and services will be added over time. The same documentation notes that the “Auto-apply new services” setting is enabled by default for spending policies, so a policy created today can extend to future services unless an administrator turns that setting off.

“The important word in Microsoft's announcement is default,” said Errin O'Connor, Founder and Chief AI Architect of EPC Group. “Nothing is being charged that an administrator cannot see and cap. But a Copilot seat that used to be a fixed line item now has a variable tail, and the policy that governs that tail is created for you unless you create your own first. The playbook exists so that the first metered task runs under a limit the organization chose.”

Two meters, governed in two places

EPC Group's playbook separates the two usage-billing systems Microsoft runs for Copilot, because they are governed in different admin surfaces and are often confused. Copilot Credits are managed under Copilot, then Cost management, in the Microsoft 365 admin center, where administrators configure spending policies, control which users and groups can consume credits, apply organization-level and user-level limits, set alerts and thresholds, route credit requests and review consumption by policy, user, group, agent and service. Copilot Studio pay-as-you-go is billed and governed separately. Microsoft's documentation also describes reader-based roles that let finance, licensing and governance stakeholders review consumption without permission to change policies.

The twelve controls, in four groups

The playbook's twelve controls fall into four groups. Decide: which billing method the organization will use — the Copilot Credit Pre-purchase Plan, pay-as-you-go, or existing prepaid capacity packs — and who owns the connected Azure subscription. Scope: create the organization's own spending policy before October 19, assign it by group rather than to everyone, and make a deliberate choice on “Auto-apply new services” for each policy. Watch: set administrator alerts and user-level threshold notifications, grant finance the reader role, and put a monthly consumption review on the calendar. Record: reconcile Copilot Studio pay-as-you-go separately, and enter the policy, its owner and its limits into the tenant's AI governance register.

That register is the eighth surface of EPC Group's 8-Surface Tenant AI Readiness Standard, the open standard the firm published in September 2026 for assessing a Microsoft 365 tenant before and during Copilot deployment. EPC Group delivers it as a fixed-scope Tenant AI Readiness Assessment while running Copilot Studio agent governance — the agents, their owners, their permitted scopes and their cost — as a standing practice.

Where EPC Group fits

EPC Group has led 300+ Microsoft Copilot initiatives (rollouts and readiness assessments) and 11,000+ enterprise engagements since 1997, figures the firm reports from its own records, and holds all six Microsoft Solutions Partner designations. Its Virtual Chief AI Officer practice runs a standing Agent Governance Office inside the client's Microsoft tenant for organizations that cannot justify a full-time AI executive; its monthly work product includes the spending-policy review the playbook describes.

Four questions IT and finance teams are asking

The full playbook is at epcgroup.net/blog/copilot-usage-based-billing-default-october-2026-spending-policy-playbook. The companion tool, the Copilot Credits spending-limit calculator, turns an expected monthly mix into credits per user and the position against the 4,000-credit default, using Microsoft's published rates.
