The engagement
I was recently engaged to review Microsoft 365 licensing as part of a billing and cost optimization effort. The goal was straightforward: identify unnecessary licensing, reduce waste where possible, and make sure the organization was not carrying costs for users or workloads that no longer needed them.
The important discovery was not simply that some licenses could be reduced. The important discovery was that the timing mattered. Several Microsoft 365 Copilot licenses were tied to annual upfront commitments, and the renewal date was close enough that action needed to happen quickly. By reviewing the subscription renewal timing before the renewal event, the organization was able to reduce the Copilot user count in time for planned offboarding activity.
Lesson learned: In the New Commerce Experience, the most valuable licensing review is often the one completed before renewal. Once a subscription renews into another committed term, the opportunity to reduce unnecessary seats may be gone until the next term boundary.
Why NCE changes the conversation
Before NCE, many organizations treated Microsoft 365 licensing as something that could be adjusted reactively. A user left, a license was removed, and the assumption was that billing would naturally follow. Under the New Commerce Experience, that assumption can be dangerous.
NCE places greater emphasis on subscription term duration, billing frequency, commitment windows, renewal behavior, and scheduled changes. Microsoft documentation states that license-based subscriptions have a prorated refund window within seven calendar days of purchase, and that the cancellation window does not reopen until the subscription renews into a new term. Microsoft also documents that scheduled changes can be configured to take effect at renewal, including increasing or decreasing license quantity, modifying the billing term and frequency, or upgrading the SKU.
That means the subscription renewal date becomes an operational control point. If a team knows the renewal date, it can make informed decisions before the commitment resets. If the renewal date is unknown or ignored, the organization may keep paying for seats that no longer map to active users, active work, or actual business value.
The Copilot example
Microsoft 365 Copilot is a strong example because it is typically licensed per user, carries a meaningful per-user cost, and is often introduced during a period of experimentation, executive interest, or departmental pilot activity. Microsoft lists Microsoft 365 Copilot for enterprise at $30.00 per user/month, paid yearly, with an annual subscription that auto-renews.
That price may be appropriate for users who receive regular value from Copilot across Outlook, Teams, Word, Excel, PowerPoint, OneNote, and the Microsoft 365 Copilot app. But it can become wasteful if licenses remain assigned to users who are leaving, users who never adopted the tool, or users who only needed temporary access during a pilot.
The hidden risk: Removing a license assignment from a user is not the same thing as reducing the subscription quantity or avoiding renewal. A billing review must inspect both assigned usage and subscription commitment details.
License assignment is not the same as subscription management
This is one of the most common gaps I see in Microsoft 365 billing reviews. Administrators often know how many licenses are assigned. Finance may know the invoice amount. Procurement may know the vendor relationship. But nobody may have a complete view of the subscription term, billing frequency, renewal date, auto-renew behavior, and whether changes must be scheduled in advance.
That separation creates risk. A tenant may look clean because unused licenses have been removed from users, but the subscription quantity may still renew at the old count. From an administrative view, the license is no longer assigned. From a billing view, the organization may still be committed.
This is why a Microsoft 365 license review should not stop at the license assignment page. It should include the commercial terms attached to each subscription.
What should be reviewed before renewal?
A good renewal review should connect technical inventory, user lifecycle data, and billing terms. The following areas are especially important:
- Current assigned licenses: Which users currently have each SKU?
- Unassigned license inventory: Are paid licenses sitting unused?
- Upcoming offboarding: Are any users scheduled to leave before or near renewal?
- Recent offboarding: Were departed users removed from license assignment but not reflected in subscription quantity?
- Subscription term: Is the subscription monthly, annual, or multi-year?
- Billing frequency: Is the annual term billed monthly or paid upfront?
- Renewal date: When does the next term begin?
- Auto-renew behavior: Will the subscription renew automatically if no action is taken?
- Scheduled renewal changes: Has the desired future quantity or billing change already been scheduled?
- Adoption data: For high-cost workloads such as Copilot, are users actually using the capability enough to justify renewal?
Practical recommendation: Maintain a renewal calendar for every material Microsoft 365 subscription. Review high-cost or high-volatility SKUs at least 60 to 90 days before renewal so there is enough time to coordinate IT, finance, procurement, HR, and business stakeholders.
Annual upfront can be useful, but it requires discipline
Annual upfront licensing is not automatically bad. For stable, well-understood workloads, it can provide budget predictability and may align well with annual planning. The issue is not the annual commitment itself. The issue is committing to the wrong quantity because no one reviewed the environment before renewal.
Annual upfront commitments work best when the organization has confidence in the user population, confidence in adoption, and a process to validate renewal quantities before the renewal date. Without that process, an annual subscription can silently turn yesterday's headcount into tomorrow's invoice.
Where monthly licensing still has value
Monthly term subscriptions usually cost more than annual commitments, but they can be useful for variable populations. Contractors, seasonal employees, pilot users, project-based teams, temporary departments, and uncertain Copilot adoption groups may be better candidates for more flexible licensing until usage patterns are proven.
The decision should not be annual versus monthly as a blanket rule. The better question is: which users are stable enough for commitment, and which users require flexibility?
A balanced model: Keep a stable baseline of known long-term users on annual commitments, then use monthly subscriptions for variable users, pilot groups, or departments still proving value. This gives the organization a way to control cost without sacrificing needed flexibility.
The 90-day NCE renewal checklist
For organizations operating under NCE, I recommend treating renewal dates as part of Microsoft 365 governance. A simple checklist can prevent expensive surprises:
- Export current subscriptions with SKU, quantity, term, billing frequency, renewal date, and auto-renew status.
- Compare subscription quantity to assigned users and identify unassigned paid inventory.
- Review HR and offboarding plans for users leaving before or shortly after renewal.
- Review adoption data for premium workloads such as Copilot, Teams Premium, Power BI, add-ons, and security suites.
- Meet with stakeholders to confirm which users still need each workload.
- Decide the future-state quantity before the renewal event.
- Schedule renewal changes where supported so the subscription renews at the intended count, term, and billing frequency.
- Document the decision so finance, IT, and leadership understand why quantities changed.
- Set the next review date immediately after completing the current renewal cycle.
What this means for consultants and MSPs
For consultants and MSPs, NCE renewal visibility should be part of every onboarding, tenant assessment, and billing review. It is not enough to ask, "How many licenses do you have?" The better questions are:
- Are these licenses direct, CSP, MCA, or another purchasing motion?
- Which subscriptions are annual, monthly, or multi-year?
- Which subscriptions are billed monthly versus annually upfront?
- What are the renewal dates?
- Which subscriptions are set to auto-renew?
- Which quantities can be reduced at renewal?
- Which licenses are assigned to users who are leaving, inactive, or underutilizing the service?
Those questions turn a basic billing review into a real advisory conversation. They also help clients avoid the frustration of discovering that a license could have been reduced yesterday but is now committed for another term.
Final thoughts
The most important takeaway from this engagement was simple: renewal dates are not administrative trivia. Under the New Commerce Experience, renewal dates are financial control points.
In this case, timely review made it possible to reduce unnecessary Copilot licensing before the annual upfront renewal created another commitment. That is the kind of practical governance that saves real money without reducing security, productivity, or business capability.
License optimization is not just about finding waste. It is about finding it early enough to act.
