Microsoft 365 License Audit: How to Stop Overpaying and Protect Against Price Increases

Most business owners don't realize they're throwing thousands of kroner away each month on Microsoft 365 licenses. They sign up, add users, and then... nothing. No review. No optimization. Just bills that keep coming, sometimes with licenses nobody even uses.

This is exactly where a Microsoft 365 license audit becomes your best friend. It's not about being cheap. It's about getting clarity on what you're actually paying for, stopping the waste, and protecting your business against surprise price increases. I've worked with dozens of Danish companies that discovered they were paying for licenses that weren't even deployed, or that had people on expensive plans when basic licenses would have worked fine.

Why Microsoft 365 License Auditing Matters for Your Bottom Line

Let's say you run a consulting firm with 25 employees in Copenhagen. You've got Microsoft 365 Business Premium licenses for everyone, which cost around 200 DKK per user per month. That's 5,000 DKK monthly, or 60,000 DKK annually. Sounds reasonable, right?

But here's what happens in most companies: Five people have left in the past year, but their licenses are still active. Three people only use email and Office documents, not the security features you're paying for. One person is using a competing tool that handles their core workflow. And two people have duplicate licenses because they were migrated twice during the last system change.

In this scenario, you might be overpaying by 15,000 DKK to 25,000 DKK every single year. That's money you could use for other priorities. That's where Microsoft 365 license audit cost optimization comes in. It gives you actual visibility into what you're buying, who's using it, and where you're bleeding money.

What Actually Happens During a License Audit

A proper Microsoft 365 license audit isn't complicated, but it does require you to look at your situation systematically.

Inventory Your Current Licenses

First, you need to know exactly what you have. How many Business Basic licenses? How many Business Premium? Are you using Microsoft 365 for Business, Microsoft 365 for Enterprise, or a combination? Most companies can't answer this off the top of their head because licenses are often managed across different departments or purchased at different times.

This is step one: getting an actual list. Your Microsoft 365 admin portal will show you this information, though it might require some digging through the billing section.

Match Licenses to Actual Users

Now comes the important part. You need to compare your licensed users against who's actually in your organization. Are there licenses assigned to people who've left? Are there inactive accounts that are still consuming licenses? Are there users with licenses they don't need?

A small marketing agency I worked with discovered they had 12 active licenses for a 10-person team. Two licenses belonged to people who'd been gone for 14 months. They were keeping them "just in case" someone returned. At 180 DKK per user monthly, that's 3,000 DKK wasted every single month, or 36,000 DKK per year.

Check Usage Patterns

Not every license is used equally. Some people use everything Microsoft 365 offers. Others just need email and OneDrive. Your audit should examine what features each user is actually accessing. If someone hasn't opened Teams in six months or doesn't use Power BI, they probably don't need an Enterprise plan.

Identifying Where You're Overpaying

Overpayment happens in specific, predictable ways. Once you know what to look for, you'll find thousands of DKK in unnecessary spending.

Unused Premium Features

Many companies buy Business Premium licenses when Business Basic would work perfectly. The difference? Business Premium includes desktop versions of Microsoft 365 apps, advanced security features, and business-class email. If your team mostly works through the web browser and doesn't need that extra security layer, you could cut your license cost by 30-40% per user.

Zombie Licenses

People leave your company. They go on long-term leave. They move departments. Licenses don't automatically disappear, though. They sit there, eating your budget. I've seen companies paying for licenses assigned to people who haven't logged in for over a year. That's pure waste.

Duplicate Licenses

This happens more often than you'd think, especially during system migrations or when multiple people manage different parts of your IT infrastructure. Someone gets a license in one system, then gets assigned another as a backup. Nobody realizes it until you look.

Overprovisioning for Roles

Not everyone in your company needs the same level of Microsoft 365. Your receptionists might just need email and basic Office access. Your developers might need enterprise-grade tools. Your finance team might need Power BI and advanced analytics. When everyone gets the same plan, you overpay for the roles that don't need it.

How to Lock in Predictable Costs and Avoid Price Surprises

Beyond just cutting waste, one of the smartest moves in a Microsoft 365 license audit is protecting yourself against future price increases. Microsoft has raised prices multiple times over the past few years, and they'll likely do it again.

Multi-Year Commitment Terms

If you're paying month-to-month for Microsoft 365 licenses, you're at the mercy of whatever price Microsoft charges next. With a multi-year commitment, you lock in today's price for 1, 2, or 3 years. This gives you budget certainty and protection.

Here's the math: If you're paying 60,000 DKK annually for your 25-person team today, and Microsoft increases prices by 8% next year, suddenly you're at 64,800 DKK. With a three-year commitment at today's price, you stay at 60,000 DKK for all three years. If they raise prices again, you don't care—your rate is locked. Over three years, that could save you 10,000 to 15,000 DKK depending on the increase schedule.

Volume Licensing Agreements

If you have 50 or more licenses, volume licensing often gives you better rates than monthly cloud subscriptions. A Microsoft representative can walk you through the options, but generally, if you're committing to multiple licenses over multiple years, you'll get a discount compared to standard pricing.

Using License Management Tools to Stay on Track

The audit is great, but staying optimized requires ongoing tracking. Without it, you'll fall back into the same patterns within 18 months.

Built-In Microsoft 365 Admin Portal

Your Microsoft 365 subscription comes with admin tools built in. The admin portal lets you see license assignments, monitor usage, and identify inactive accounts. It's not fancy, but it's free and it works. You can see which users have licenses, which licenses are assigned to which users, and generate reports on login activity.

Third-Party License Management Portals

If you want more sophisticated tracking, several free and paid platforms consolidate license visibility across your entire business. These tools pull data from your Microsoft 365 environment and present it in an easy-to-read dashboard. They'll alert you when licenses are unused, flag potential redundancies, and sometimes even recommend optimization opportunities.

Many of these tools are free for basic features. They're especially useful if you have multiple Microsoft 365 subscriptions or if your IT team is managing licenses manually across different systems.

Automatic Headcount Tracking

The best protection against accidentally overpaying is automating your license tracking to match your actual headcount. When someone joins, their license assignment happens automatically based on their role. When someone leaves, their license is deprovisioned automatically. This prevents zombie licenses and duplicate assignments from piling up.

Set this up through your identity management system (like Azure AD) and configure automatic licensing policies. Yes, it requires some initial setup, but once it's running, it saves you constant manual management and catches errors before they cost you money.

Creating Your Microsoft 365 License Audit Roadmap

If you haven't done an audit yet, here's how to approach it without overcomplicating things:

Step 1: Get Your Current State Pull a report from your Microsoft 365 admin portal showing all assigned licenses and users. Spend a few hours comparing this list to your actual employee roster. Create a simple spreadsheet showing licenses, users, and any mismatches.

Step 2: Map Actual Usage Look at login activity and feature usage for the past three months. This tells you who's active and what they're actually using. You can get detailed reports from the Microsoft 365 admin portal.

Step 3: Identify Savings Opportunities Based on your comparison, list where you can optimize: unused licenses to remove, downgrades available, or better license tiers for specific roles.

Step 4: Calculate the Impact How much would you save if you removed inactive licenses? How much if you downgrades users who don't need premium features? This calculation shows your stakeholders why this matters.

Step 5: Plan Your Commitment Strategy Decide whether multi-year commitments make sense for your business. Consider your growth trajectory, budget stability, and how much price protection matters to you.

Step 6: Implement and Monitor Make the changes. Set up automated license management if possible. Schedule a quarterly review to keep things on track.

Real Example: A Danish IT Services Company

One of my clients was an IT services company in Aarhus with about 40 employees. They'd been paying 8,000 DKK monthly for Microsoft 365 licenses without ever auditing what they actually needed.

The audit revealed three major issues: First, they had 42 assigned licenses for 40 employees (two people who'd left still had active accounts). Second, they were buying Business Premium for everyone, including receptionists who only needed email. Third, they weren't locked into any pricing, so they'd been hit with two price increases in the past 18 months.

Here's what we did: Removed the two inactive licenses. Downgraded their administrative staff and receptionists to Business Basic. For their technical team, we kept Business Premium but negotiated a multi-year commitment at a locked-in price.

The result? They went from 8,000 DKK monthly to 5,600 DKK monthly. That's 28,800 DKK saved annually. The multi-year commitment protected them from the next price increase cycle, which came six months later. In three years, their total savings would be around 86,000 DKK.

Common Mistakes to Avoid During Your Audit

Don't assume everyone who has a license needs the license they have. Verify. Don't leave inactive accounts on your list thinking they'll come back. Remove them and reassign licenses if people return. Don't ignore smaller license types thinking the savings won't matter. Small waste multiplied across your team adds up fast. Don't forget about all your subscription locations. Sometimes licenses are scattered across different billing accounts or subscription agreements. Find them all.

Frequently Asked Questions

How often should I audit my Microsoft 365 licenses?

At minimum, once a year. But quarterly is better if you have high employee turnover or frequent role changes. Even a quick 30-minute review each quarter prevents major buildup of unused licenses. Many companies that do monthly tracking notice they save 5-10% just from catching small issues early.

Can I do a license audit myself, or do I need help?

You can definitely do a basic audit yourself using the Microsoft 365 admin portal. It takes a few hours, but it's free and gives you valuable insight. For more detailed analysis or if you have complex licensing across multiple subscriptions, professional help from an IT management company can be worth the investment. They'll often find optimization opportunities that pay for their service within the first few months.

What if we're not sure which license plan is right for each person?

Most companies have three categories: people who just need email and basic Office (Business Basic), people who need the full desktop apps and collaboration features (Business Premium), and specialized teams who might need Enterprise plans. Start with that framework. Your IT team or Microsoft representative can help you match specific roles to the right licenses.

Do multi-year commitments actually protect me from price increases?

Yes, absolutely. When you sign a multi-year agreement with a locked-in price, Microsoft cannot raise your rate during that commitment period. However, the commitment does mean you're locked in for that duration. Make sure your license forecast is accurate before committing to three years. A conservative estimate is safer than overcommitting.

What happens to my licenses if I reduce them after an audit?

You simply assign the licenses to the users who need them and let the unused licenses go unused until your billing cycle. You stop being charged for licenses that aren't assigned. If you purchased through a monthly subscription, unused licenses stop incurring charges immediately. If you're on a multi-year commitment, the cost is already locked in for the total quantity, but you can reassign licenses within your organization as needs change.

Conclusion

A Microsoft 365 license audit cost optimization is one of the easiest, highest-return projects most businesses can do. You're not cutting corners or reducing functionality. You're simply making sure every kroner you spend is actually delivering value to your organization.

Most Danish companies find 20-30% in optimization opportunities during their first audit. That might mean removing unused licenses, downgrades people who don't need premium features, or locking in multi-year commitments at better rates. The savings add up to thousands of DKK annually.

Start with a simple inventory of what you currently have. Spend a few hours comparing licenses to your actual employee list. Look for usage patterns and mismatches. Then make the easy wins: remove inactive accounts, downgrade licenses where appropriate, and lock in stable pricing.

Your Microsoft 365 investment should work for you, not drain your budget. An audit ensures that's exactly what happens.
