Why Copilot Licensing Confusion Is Expensive
Microsoft 365 Copilot at $30 per user per month, GitHub Copilot Business at $19 per user per month, and Copilot Studio at $0.01 per message are three separate purchasing decisions — not one. No single Copilot licence covers all three environments. Organisations that conflate them typically discover the mismatch after an annual subscription commitment has been made, by which point the cancellation window has passed and the overspend is locked in.
The commercial consequence of treating Copilot as a single product is overspending: organisations that purchase Microsoft 365 Copilot for developers expecting code completion assistance, or that buy GitHub Copilot expecting meeting summaries in Teams, discover the mismatch after the annual commitment is made. The reverse problem — assuming one Copilot licence covers multiple use cases — is equally common and equally expensive when it leads to a compliance gap or a second-round procurement to address the missing capability.
This guide provides the decision-making clarity that prevents both failure modes.
Microsoft 365 Copilot: The Productivity AI for Knowledge Workers
What It Is and What It Does
Microsoft 365 Copilot is the AI assistant embedded within the standard Microsoft 365 application set: Word, Excel, PowerPoint, Outlook, Teams, and OneNote. Its defining characteristic is contextual grounding — it accesses the organisation's Microsoft Graph data (emails, documents, calendar entries, Teams conversations, SharePoint content) to provide AI assistance that is specific to the user's actual work context rather than generic AI responses.
Practical use cases include drafting an email that references the user's recent project correspondence, summarising a Teams meeting transcript and identifying action items, generating a PowerPoint from a one-page brief, performing natural language data analysis in Excel, and creating a first-draft Word document from notes. The quality of these outputs depends heavily on the organisation's Microsoft Graph data hygiene — users with well-organised SharePoint permissions and active Teams usage get significantly more accurate contextual responses than users in poorly governed M365 environments.
Licensing Structure
Microsoft 365 Copilot is a per-user add-on licence, priced at $30 per user per month at enterprise list. It requires a qualifying base licence: Microsoft 365 E3, E5, E7 (from May 2026 GA), Business Standard, or Business Premium. Users on F1 or F3 frontline SKUs do not qualify without a base licence upgrade. The add-on is committed on an annual term under NCE, with no mid-term reduction available. Monthly-term options exist at a 20 percent premium. The add-on must be assigned to individual named users — it cannot be shared or used on a shared workstation basis.
Since late 2025, the M365 Copilot add-on includes access to Copilot Studio features for internal agents, role-based Copilots (Copilot for Sales, Service, Finance), and Copilot Pages at no additional charge for licensed users. This consolidation has meaningfully increased the per-licence value.
Who Needs It
Microsoft 365 Copilot is appropriate for knowledge workers whose primary tools are the Microsoft 365 application suite — executives, managers, analysts, legal professionals, finance teams, HR, marketing, and operations roles that rely heavily on email, documents, meetings, and data analysis. It is not the right product for developers (who need GitHub Copilot), frontline workers with primarily mobile-only Microsoft interactions (who may not need the full add-on), or process automation builders (who need Copilot Studio's agent capabilities).
Copilot Studio: The Agent and Automation Builder
What It Is and What It Does
Copilot Studio is Microsoft's low-code platform for building custom AI agents. An agent in this context is an automated AI workflow that can: respond to natural language queries by connecting to a specific data source (an HR policy database, a CRM, a ticketing system), execute multi-step business processes (creating a support ticket, routing an approval request, generating a report from query parameters), and integrate with external APIs or data connectors. Copilot Studio agents can be surfaced through Teams, web chat interfaces, SharePoint sites, or any channel that supports Microsoft's bot framework.
The distinction from Microsoft 365 Copilot is fundamental: M365 Copilot assists individual users within their M365 applications; Copilot Studio builds organisation-wide agents that operate as automated processes. An IT helpdesk agent built in Copilot Studio handles incoming employee requests, queries the knowledge base, and creates tickets without individual Copilot seat licences for each employee who interacts with the agent.
Licensing Structure
Copilot Studio operates on a consumption billing model through Copilot Credits for use cases beyond the included allocation. As of late 2025, standard M365 Copilot licence holders receive Copilot Studio access for building and running agents for internal licensed users at no additional per-session cost. Advanced use cases — external-facing agents serving users who do not hold M365 Copilot licences, high-volume automated workflows, and enterprise-scale integrations — consume Copilot Credits, which are purchased in packs through the Microsoft Azure marketplace or direct agreements.
The important licensing distinction is this: building a Copilot Studio agent for internal use by employees who already hold M365 Copilot licences costs nothing additional. Building an external customer-facing agent, or running agents for employees who do not hold M365 Copilot licences, incurs consumption costs. Organisations must carefully map their Copilot Studio use case to the appropriate billing model before deployment.

What It Is and What It Does
GitHub Copilot is a completely separate product from Microsoft 365 Copilot. It is an AI coding assistant that operates inside developers' integrated development environments — VS Code, Visual Studio, JetBrains IDEs, Neovim, and others. It provides code completion as developers type, generates entire functions from natural language comments or function signatures, assists with unit test writing, helps with code documentation, and can explain existing code sections. GitHub Copilot has no connection to Microsoft 365 applications, no access to the M365 Graph, and no overlap with the M365 Copilot licence.
A developer who holds an M365 Copilot licence gets no GitHub Copilot capability from that licence. A developer who holds a GitHub Copilot licence gets no Teams meeting summaries or Outlook email drafting assistance from that licence. The two products are parallel, not overlapping.
Licensing Structure
GitHub Copilot is licensed at three tiers in 2026. Individual tier at $10 per user per month targets individual developers and very small teams. It provides core code completion and generation with no organisational management features. Business tier at $19 per user per month is the standard enterprise choice, adding organisation-wide policy controls (blocking Copilot suggestions for specific file types or code patterns), audit logging, and the ability to exclude files from Copilot's training context for IP protection. Enterprise tier at $39 per user per month adds GitHub Copilot Knowledge Bases — the ability to connect internal repositories, documentation, and codebases as additional context for Copilot suggestions — plus pull request summaries, fine-tuned models, and GitHub.com integration features.
GitHub Copilot is purchased through the GitHub commercial channel, not through standard M365 procurement. Organisations with GitHub Enterprise licences can consolidate GitHub Copilot into that agreement. Organisations without a GitHub Enterprise relationship manage GitHub Copilot as a separate vendor subscription, with billing through GitHub rather than the Microsoft EA or MCA-E structure.
Who Needs It
GitHub Copilot is exclusively for professional developers who write code as a primary work activity. Software engineering teams, DevOps engineers, data engineers, and platform engineers benefit from GitHub Copilot. IT administrators, business analysts, and non-coding knowledge workers receive zero value from a GitHub Copilot licence and should not be included in GitHub Copilot seat counts.
Copilot Chat: The Free Tier
What It Is and What It Does
Copilot Chat is the no-additional-cost AI capability available to all Microsoft Entra account holders with an eligible M365 subscription. It provides conversational AI assistance via a chat interface accessible through the Microsoft 365 web portal, Teams, and the Microsoft Edge sidebar. Copilot Chat can answer general knowledge questions, assist with document creation from scratch, summarise content the user provides directly, and access some web-grounded content in Microsoft Edge.
Copilot Chat does not access the user's Microsoft Graph data within applications. It does not provide in-application assistance — it does not summarise the meeting the user is currently attending, draft an email based on recent project correspondence, or analyse a spreadsheet in Excel. These capabilities are exclusive to the paid M365 Copilot add-on.
Licensing Structure
No separate licence is required. Copilot Chat is included in eligible M365 subscriptions at no additional cost. It does not count against any M365 Copilot seat allocation. It is a zero-cost AI entry point for employees who do not hold M365 Copilot licences, and it provides basic AI assistance that may reduce the number of M365 Copilot licences an organisation needs if the use case population includes users who would benefit from general AI assistance but do not require deep M365 application integration.
The Interaction Rules: What Changes When You Have Multiple Products
Organisations deploying multiple Copilot products need to understand how the licensing interactions work in practice.
M365 Copilot and Copilot Studio Together
An M365 Copilot licence includes Copilot Studio access for building agents used internally by other M365 Copilot licence holders. If an organisation has 500 M365 Copilot licences and wants to build a Copilot Studio agent for those 500 users, no additional licence is required. If the organisation wants to extend the agent to 5,000 employees who do not hold M365 Copilot licences, those interactions consume Copilot Credits. The boundary between included and charged use is the M365 Copilot licence: licensed users get Copilot Studio interaction at no added cost; all others consume credits.
M365 Copilot and GitHub Copilot Together
These are completely parallel licences with no interaction. An organisation deploying both maintains two separate licence counts: M365 Copilot per-user licences for knowledge workers through the M365 commercial channel, and GitHub Copilot Business or Enterprise per-user licences for developers through GitHub. There is no bundled pricing for purchasing both, no shared entitlement, and no cost reduction from holding both. Development organisations that also hold M365 Copilot licences must purchase and manage both products independently.
The E7 Exception: Where Copilot Becomes Part of the Base SKU
Microsoft 365 E7, with general availability expected May 2026, changes the bundling dynamics for organisations already on M365 E5. At $99 per user per month, E7 includes M365 Copilot within the base SKU rather than as a separate add-on. For E5 customers ($57 per user per month) planning full-fleet Copilot deployment ($30 per user per month, totalling $87), E7 is $12 per user per month more and delivers additional security and identity capabilities through the bundled Entra Suite.
E7 does not include GitHub Copilot. An organisation that upgrades to E7 still requires a separate GitHub Copilot licence for its development team. E7 also does not eliminate Copilot Studio consumption costs for external-facing agents. E7 addresses the M365 Copilot add-on pricing specifically; the other Copilot products remain separate regardless of the M365 base SKU tier. The M365 SKU stack runs E1 through E7, with E7 as the current highest tier. E5 is not the top SKU, and buyers should not plan their licensing architecture on the assumption that E5 represents the most comprehensive available tier.
Decision Guide: Which Copilot Products Does Your Organisation Need?
For knowledge workers in Microsoft 365 applications: M365 Copilot add-on at $30 per user per month (or included in E7). Requires E3, E5, E7, Business Standard, or Business Premium base licence.
For software developers writing code: GitHub Copilot Business at $19 per user per month (standard enterprise) or Enterprise at $39 per user per month (with knowledge bases and fine-tuned models). Purchased separately through GitHub.
For building automated AI agents and workflows: Copilot Studio, included with M365 Copilot for internal licensed users. Copilot Credits required for external-facing agents or high-volume consumption beyond the included allocation.
For employees who need basic AI chat assistance without deep M365 integration: Copilot Chat, included at no cost in eligible M365 subscriptions. No separate licence required.
Most enterprise organisations end up needing a combination: M365 Copilot for their knowledge worker population, GitHub Copilot for their development team, and Copilot Chat for the broader employee base. The total Copilot cost picture requires independent modelling across all three product lines, not a single per-user estimate. Our Microsoft EA negotiation specialists provide comprehensive Copilot licensing assessments that map each product to the right user population and identify the most cost-effective acquisition structure for each component.
