Microsoft 365 is rarely an expensive service in itself. What makes it expensive is the way companies manage it, or rather the lack of management. Licences are bought ad hoc, plans are chosen with too much margin, and the accounts of people who have left stay active for months. After a year or two the bill can be several dozen per cent higher than real needs would justify. The good news is that most of this money can be recovered without giving up anything that is actually being used.

Where the budget most often leaks

Before you start optimising, it is worth knowing where the biggest leaks usually are.

  • Accounts of former employees. An active, paid licence for someone who left six months ago is pure waste, and a security risk on top of that.
  • Over-specified plans. The whole company on the most expensive plan, even though only a handful of people use its features.
  • Duplicated tools. A separate subscription for a messenger, file storage or video conferencing, even though the same features are already in the Microsoft 365 plan.
  • Licences bought and not assigned. Paid seats that simply sit unused in the admin panel.

In licence reviews we regularly find somewhere between a dozen and several dozen per cent of costs to recover. Usually it is not about any major change, just switching off what the company pays for with no reason.

Understand what you are paying for

Microsoft 365 for business is built on several plans, and the difference between them is mainly the set of security and management features, not the Office apps themselves.

  • Cheaper plans give email, apps and basic cloud services.
  • More expensive ones add advanced security, device management through Intune and Defender protection.
  • There are also plans exclusively for frontline workers, who mainly need email and simple tools rather than the full suite.

The key is matching the plan to the role, not buying one, most convenient variant for everyone.

Mixed licensing, or paying for roles

Not everyone in the company needs the same thing. A warehouse worker who uses email and one application does not need the same plan as an accountant working all day in Excel and many cloud services. Splitting the team by role and choosing plans separately for each group is the simplest way to pay for real needs.

Such a mixed model takes a moment to analyse, but it usually delivers the biggest saving, because it eliminates the most expensive mistake: everyone on a single, high plan.

A rhythm instead of a one-off exercise

Optimising costs once a year is not enough, because the company changes all the time. It is worth setting a simple rhythm.

  1. Every month, check whether there are licences assigned to inactive accounts.
  2. Build licence release into the offboarding process, just like blocking the account.
  3. Once a quarter, review whether the plans still match how people actually work.
  4. Before buying a new tool, check whether that feature is not already in your plan.

These four habits keep the bill from quietly starting to grow again.

Beware of false savings

Cutting costs makes sense only when it does not take away what genuinely protects the company.

  • Do not give up a plan with security features just to lower the bill, if those features are actually turned on and used.
  • Do not delete a departing employee’s account straight away, because you may lose data you need. Secure it first, then release the licence.
  • Remember that an independent Microsoft 365 backup is not an unnecessary cost, but a condition for recovering data after a failure or a mistake.

Good optimisation means paying for what is genuinely needed, not cutting blindly.

Summary

Most companies pay more for Microsoft 365 than they have to, and usually not because of expensive features, but because of a lack of order in licensing. Reviewing accounts, matching plans to roles and a simple control rhythm can lower the bill with no loss to the work. If you want to check how much can be recovered in your company, we help bring order to software licensing and to the whole Microsoft 365 deployment so that payments match real needs. A good start is a short review of how many accounts and which plans you pay for today.
