If you’re running a small business on Microsoft 365, there’s a good chance you’re spending more than you need to. After a decade of managing M365 environments, I see the same licensing mistakes over and over again.
Here are the five most common signs your business is overpaying — and what you can do about each one.
1. You Have Licenses Assigned to People Who Left
This is the most common issue I see. An employee leaves, their account gets disabled, but their license stays assigned. At $12–22 per user per month, a handful of forgotten licenses adds up fast.
Quick fix: Run a report of all licensed users and compare it to your current employee roster. Reclaim any licenses assigned to inactive accounts.
2. Everyone Has the Same License Tier
Not every employee needs the same M365 plan. Your front-desk receptionist probably doesn’t need the same E3 license as your project manager who lives in SharePoint and Teams all day.
Quick fix: Audit actual usage by user. Microsoft’s usage reports in the admin center will show you who’s using what. Downgrade users who only need email to a cheaper plan.
3. You’re Paying Monthly Instead of Annual
Microsoft offers a significant discount for annual commitment pricing versus month-to-month. If your team has been stable for a while, you’re leaving money on the table.
Quick fix: Check your billing cycle in the admin center. If your headcount is stable, switch to annual billing on your next renewal.
4. You Have Trial Licenses That Expired (But You’re Still Paying)
Many businesses start trials of add-on products like Power BI Pro or Project Plan, forget about them, and end up on a paid plan they never actually use.
Quick fix: Check for any add-on subscriptions in your billing dashboard. Cancel anything your team isn’t actively using.
5. You’re Buying Third-Party Tools for Things M365 Already Does
This one is subtle. I’ve seen businesses paying separately for survey tools when they have Microsoft Forms, file sharing platforms when they have SharePoint, or project management tools when they have Planner — all included in their existing M365 plan.
Quick fix: List out every SaaS tool your business pays for, then check whether M365 has a built-in equivalent. You might be surprised.
The Bottom Line
Most small businesses I assess are overpaying by $200–500 per month on licensing alone. That’s $2,400–6,000 per year that could go somewhere more useful.
