Timing Your Microsoft 365 License Optimization: When to Act in the Renewal Cycle
Why Timing Is Critical in M365 Optimization
Timing can make or break your Microsoft 365 (M365) cost optimization efforts. Microsoft’s renewal cycle is a well-oiled sales engine designed to maximize revenue.
As soon as one contract is signed, Microsoft’s account team begins planning how to upsell and expand your spend for the next renewal. If you wait passively, you’re following Microsoft’s timeline instead of your own.
This often means missing the optimal window to trim unused licenses, right-size your subscriptions, and push back on price increases. Read our ultimate guide to M365 licensing and negotiations.
Leaving optimization too late erodes potential savings. Many enterprises make the mistake of starting cost-cutting exercises only a month or two before renewal.
By then, the opportunity to identify and eliminate waste (like inactive “shelfware” licenses) has largely passed — you’ve paid for those excess licenses all along, and Microsoft has likely baked them into your renewal quote.
Last-minute efforts also undermine negotiation leverage. When time is short, Microsoft knows you’re up against a deadline and can pressure you into accepting the status quo or a rushed deal.

The 12-Month Window — Early Preparation Advantage
Nine to twelve months before renewal is the ideal time to kick off your M365 optimization. At roughly a year out, you have the luxury of time to do things properly.
Start with a comprehensive internal license audit of all Microsoft 365 services.
This early preparation window allows you to gather detailed usage data across the organization: Which licenses are heavily used? Which premium features (such as those in E5 plans) remain untouched by certain user groups? Where do you have unused licenses sitting idle? With 9–12 months to go, you can afford to dig deep and involve stakeholders without the pressure of an imminent deadline.
Starting this early also gives you time to reset your license baseline before Microsoft even sends a renewal proposal. For example, if your analysis at month 12 finds that 200 out of 1,000 Microsoft 365 E5 licenses are unassigned or inactive, you have ample time to plan their removal.
By the time Microsoft’s sales team begins crafting your renewal quote (often around 3–6 months before expiration), those 200 licenses can be off the books or downgraded. In effect, you’re ensuring Microsoft’s proposal is based on a leaner, optimized footprint rather than an inflated one.
The 12-month preparation window also lets you set clear cost-saving targets (e.g., “reduce overall M365 spend by 15%”) and begin socializing them internally.
You can engage IT, finance, and department heads to build consensus on changes, such as removing certain add-ons or moving some users to more affordable license tiers.
In short, acting a year ahead gives you breathing room to audit, plan, and execute optimizations methodically — and this early groundwork directly translates into savings and stronger negotiating power.

Mid-Term License Audits — Capturing Waste Early
Don’t wait until the contract year ends to start trimming fat. Mid-term license audits (for instance, at the midpoint of your agreement or annually during a multi-year term) are a strategic way to capture waste early.
Over a year, organizations change: employees join or leave, projects ramp up or wind down, and usage patterns shift.
By running an audit mid-term, you can spot unused or underutilized licenses well before the renewal crunch.
It’s common for companies to find that 10–30% of their M365 licenses are assigned to users who no longer need them or aren’t using the services to their full extent. Identifying these now means you can take action instead of carrying that cost for the rest of the term.
Mid-cycle audits often reveal hidden overspend from incremental changes. Perhaps you’ve been adding licenses for new hires or projects without reclaiming any when roles change. These true-ups and add-ons can quietly inflate your license count beyond what’s required. A mid-term audit shines a light on this.
For example, you might discover that dozens of users have an expensive Power BI or Phone System add-on that they haven’t used in months, or that multiple departments bought extra Teams telephony licenses that overlap.
Correcting these mid-term — by reallocating or removing licenses — has immediate benefits. In subscription models, you can reduce license quantities in the next billing cycle to realize savings immediately.
In enterprise agreements where reductions must be implemented at renewal, a mid-term audit ensures you enter the renewal process with a plan: you know exactly which licenses will be dropped and which users can be downgraded. This prevents a frantic scramble later.
Mid-term corrections also ease renewal negotiations; you won’t be negotiating under the pressure of unexamined bloat, because you’ve already done a lot of cleanup in advance.
In summary, regular mid-term audits serve as a “health check” that keeps your Microsoft 365 environment lean and avoids unpleasant surprises when the renewal date approaches.
Last-Minute Optimization — Risks and Limits
What if you wait until the last minute (say, within 90 days of renewal) to optimize?
In short: expect limited gains and higher risks. Auditing your licenses just a few weeks or even a couple of months before renewal is too late to capture the full value of optimization.
By this point, Microsoft is likely to have your renewal quote in the works or already delivered. That quote will assume your current (possibly bloated) usage as the baseline. Trying to shed licenses at the eleventh hour can be a daunting task.
Microsoft’s team may resist or question sudden drops in quantity, especially if you’re in an Enterprise Agreement where reductions typically occur only at renewal.
In theory, you can still choose not to renew certain licenses, but in practice, if you haven’t signaled those changes earlier, the negotiations can become contentious.
Microsoft might argue you needed those licenses all along (since you carried them until now), and you may find them less willing to offer large discounts on a sharply reduced volume with so little notice.
Operationally, last-minute audits also pose challenges. Your internal team has minimal time to validate findings or implement changes. Imagine discovering one month out that 20% of your users could be on cheaper plans — you’d then have to scramble to communicate and execute those downgrades or removals.
Often, organizations end up abandoning late-found savings because there’s simply no time to enact them properly before renewal paperwork must be finalized.
Moreover, delaying optimization squeezes your negotiation timeline. With the clock ticking, Microsoft holds the advantage.
They know you can’t afford to let the contract lapse, so you’re less likely to push back on pricing or terms. You also lack the leverage that comes from having done thorough homework; without an internal audit completed months earlier, you’re negotiating with hazy data and no alternative plan, which Microsoft’s reps certainly recognize.
Finally, in recent years, Microsoft has taken steps to discourage last-minute deal-making. They often offer better pricing incentives for early renewals and may have internal policies that penalize deals signed past a certain date.
All of this means that by waiting too long, you risk being locked into inflated quantities and possibly even higher prices. The bottom line: trying to optimize in the final 90 days is a high-risk, low-reward strategy. It’s far safer and more effective to start much earlier.
Aligning Optimization with Microsoft’s Sales Calendar
When planning when to optimize M365 costs, savvy customers consider Microsoft’s calendar. Microsoft’s fiscal year ends on June 30, and this timing can significantly impact your negotiation leverage.
The months of April–June (Microsoft’s Q4) are typically a frenzied sales period. Account teams are under intense pressure to hit year-end quotas, which means they’re often more willing to offer concessions, discounts, or special deals to close renewals in that window.
If your renewal naturally falls in Microsoft’s Q4, you’re in a strong position to capitalize on their fiscal year urgency. By entering serious negotiations in April or May, you can often extract a sweeter deal — the sales reps know that if they miss booking your renewal by June 30, it hurts their numbers.
They have every incentive to get your signature in Q4, even if it means sweetening the pot with extra cost savings or favorable terms.
But what if your renewal isn’t in the middle of the year?
Microsoft also works on a quarterly rhythm. Quarter-ends (September 30, December 31, March 31) are mini-deadlines when regional sales targets peak. A strategy we’ve used with clients is to align key negotiation milestones with these quarter-end dates.
For example, if your M365 renewal is due in October (Q2 of Microsoft’s fiscal year), you might time your final pricing discussions for late September. The goal is to catch Microsoft when hitting the quarterly number is top of mind.
By doing so, you increase the chances that your requests for discounts or flexible terms will get approved by Microsoft’s deal desk — because the account team is eager to secure your deal in the current quarter.
Using timing to your advantage sometimes requires creativity.
Some enterprises will extend an existing agreement by a month or two (via a short-term bridging agreement) specifically to land their renewal in a more opportune quarter.
Others start renewal talks early but plan to finalize them during Microsoft’s Q4, even if their term expires in August or September.
Of course, there’s a balance: you want Microsoft feeling deadline pressure, but you don’t want to cut it so close that the paperwork can’t be processed or that you’re risking a lapse in coverage.
The key is to plan and build in a buffer, so you can use Microsoft’s fiscal calendar without being trapped by it.
In summary, timing your renewal activities to coincide with Microsoft’s sales cycle, especially their fiscal year-end, can significantly improve your negotiation outcome. It turns the vendor’s internal deadlines into your leverage.
Just be mindful that Microsoft is also aware of this game; in fact, they often encourage early renewals to avoid quarter-end logjams.
So, use the calendar to your advantage, but maintain control over your timeline to avoid being pressured into a premature or suboptimal deal.
Building a Year-Round Optimization Cycle
The most effective organizations view Microsoft 365 license optimization as a continuous, year-round process, rather than a one-time event.
This involves establishing a consistent cadence of monitoring and adjusting your license usage throughout the entire contract cycle.
A best practice is to combine mid-term audits with pre-renewal audits into a unified strategy. For instance, conduct a lighter “health check” audit every 6 or 12 months, and then a deep-dive audit in the 9–12 months pre-renewal window.
By doing this, you create a feedback loop: the findings from your mid-term review inform immediate adjustments (such as cleaning up inactive accounts or consolidating redundant applications), while also feeding into your next renewal preparation.
Then, the pre-renewal audit refines the picture with fresh data and sets the stage for negotiation. This dual approach ensures that optimization isn’t something you scramble to do at the end — it’s baked into your operational rhythm.
A year-round cycle also involves ongoing monitoring of seat usage and product overlap. Modern M365 admin centers and third-party tools can provide usage dashboards. Assign someone (or a team) to regularly review these metrics.
Are there spikes in unassigned licenses? Did a department purchase a few Power BI Pro licenses that duplicate functionality you already have elsewhere?
Is a certain security add-on being assigned universally, but only half of the users utilize it? By catching such issues in real-time, you can make incremental fixes (such as re-harvesting licenses when an employee leaves or pausing new license purchases in areas of low adoption) instead of letting inefficiencies accumulate.
This continuous vigilance significantly reduces renewal stress. When renewal time comes, you’re not starting from zero with a massive clean-up project.
Instead, you have up-to-date records, a well-groomed license environment, and perhaps only minor fine-tuning needed. Moreover, a culture of continuous optimization sends a message to Microsoft as well: your organization is always on top of its license usage and spend.
Vendors are less likely to push frivolous add-ons or excessive upgrades if they know you’re scrutinizing every license for value.
In essence, year-round optimization makes cost management a business-as-usual activity, leading to smaller, more manageable adjustments at renewal rather than seismic overhauls.
Practical Roadmap for Timing M365 Optimization
To translate these concepts into action, here’s a practical timeline for when and how to act in the renewal cycle:
- Month 12: Kick off a pre-renewal internal audit. Form your core project team (IT, procurement, finance) and gather baseline data on license counts and usage. Start identifying obvious surplus (e.g., unused subscriptions, duplicate tools) and flag them for potential removal.
- Month 9–6: Using audit data, model an optimized license baseline. Determine the target state for renewal — how many of each license should you have if you eliminate waste and right-size your resources? Engage department leaders to validate these assumptions. By 6 months out, communicate to Microsoft (or your reseller) that you are conducting a thorough review. This sets the expectation that you will come to the table with a deliberate plan (and not simply accept their numbers).
- Month 6–3: Prepare your negotiation case using the data collected. Lock down the list of licenses to drop or reduce, and quantify the cost savings. Also, forecast any new needs (so you can negotiate pricing for additions or changes). Begin preliminary talks with Microsoft’s team, sharing high-level findings without revealing your final walk-away points. By 3 months out, you should be in active negotiation, backed by clear usage evidence and a solid business case for any reductions or discounts you’re requesting.
- Mid-Term (Annually): Separately from the renewal countdown, run a “health check” audit every year (for multi-year agreements) or at the midpoint of your contract. Treat it as a mini-optimization project: clean up inactive users, verify that license assignments still match roles, and check that new initiatives haven’t introduced unplanned license creep. Use these findings to make adjustments immediately (where possible) and to inform your next renewal strategy well in advance.
Following this roadmap ensures that timing is on your side. You’ll have addressed most issues by the time renewal discussions heat up, and you’ll use the remaining months to drive home the value of your optimizations in negotiations.
Common Pitfalls in Timing Microsoft 365 Optimization
Even with the best intentions, some timing missteps can derail your Microsoft 365 cost optimization.
Watch out for these common pitfalls:
- Waiting until Microsoft presents a proposal: If you only start your optimization effort when Microsoft hands you a renewal quote, you’re already behind. That proposal usually arrives just a few months (or even weeks) before expiration, leaving little room to validate or challenge its assumptions. By then, Microsoft had set the narrative (and the numbers). Avoid this trap by starting your analysis well before Microsoft releases theirs. Ideally, you want to influence the quote (through earlier license reductions and signals to the account team about your plans) rather than just react to it.
- Relying solely on Microsoft-provided reports: Microsoft will provide usage reports and recommendations through their portals or offer a Software Asset Management engagement. While useful as a data point, don’t rely solely on vendor-provided insights. These reports might not highlight all optimization opportunities — after all, Microsoft isn’t incentivized to point out where you can cut licenses. Additionally, Microsoft’s view might overlook contextual factors (e.g., a license is marked as “used” because an account is active, but the user left last month and no one updated the system). Always cross-check with your records and, if possible, use independent tools or advisors to obtain an objective assessment of your environment.
- Skipping mid-term audits in dynamic user environments: In organizations with stable headcount and little change, one big pre-renewal audit might suffice. But that’s rarely the reality. If your environment is dynamic — frequent hires and exits, reorganizations, new projects — skipping a mid-term audit is a mistake. You risk accumulating a mountain of unnecessary licenses and missing the chance to correct course early. We’ve seen fast-growing companies overpay massively at renewal because, over a year or two, they over-provisioned licenses during growth spurts and never revisited those allocations. Regular check-ups ensure you’re not paying for last year’s exuberance or covering licenses for employees who left months ago. Don’t let a dynamic environment become an excuse for waste; make mid-term reviews a standard practice.

FAQ
When is the best time to optimize Microsoft 365 costs?
9–12 months before renewal, combined with annual mid-term audits. Starting early gives you time to identify and address inefficiencies, while mid-term check-ups help keep your usage on track throughout the contract.
Is a mid-term license audit worthwhile?
Yes — it identifies unused seats and oversubscribed services long before renewal. Mid-term audits prevent costly surprises by catching shelfware early, so you’re not stuck paying for a year’s worth of unused licenses.
What happens if I optimize too late?
If you wait until the last 1–2 months, Microsoft locks in your renewal quantities based on the status quo, and you lose leverage. Last-minute changes are hard to execute, and you may end up accepting a higher-cost deal with little room to negotiate or adjust licenses.
Should I align my audit with Microsoft’s fiscal year?
Yes — timing audits and negotiations to Microsoft’s sales calendar can improve your leverage. For example, having your proposal ready by Microsoft’s Q4 (end of June) or another quarter-end can push their team to offer better concessions to close your deal within their target period.
Do I need both mid-term and pre-renewal audits?
Yes — they serve different purposes. Mid-term audits reduce waste during the contract (so you stop bleeding cash on unused licenses), and pre-renewal audits maximize leverage by ensuring you go into renewal discussions with the cleanest, lowest-cost baseline. Both are essential to avoid last-minute scrambling and to achieve the best overall savings on Microsoft 365.
