You manage Microsoft 365 licences and cost by matching licences to what people actually need, removing unused seats, reviewing regularly, and choosing the right plans for different roles. Across a whole company, this often saves real money without anyone losing the tools they use. Microsoft 365 is easy to over-buy and under-review, so a bit of attention pays off.

Licence cost creeps up quietly as a firm grows. Here’s how to keep it sensible.

1. Match licences to roles

Not everyone needs the same plan. Matching the licence to what each role actually uses means you pay for the tools people need and not for ones they do not, which can make a real difference at scale.

2. Remove unused seats

Licences for people who have left, or seats sitting idle, are pure waste. Reviewing and removing them is one of the quickest ways to cut cost, especially when offboarding has been patchy.

3. Review regularly

Your needs change as you grow and as Microsoft changes its plans. A regular review keeps your licensing aligned with both, so you are not stuck on an arrangement that no longer fits or paying for more than you use.

4. Get the security you need included

Some plans include security features you would otherwise pay extra for. We help you choose plans that cover the protection you need, so you get good security and good value together.

A real example: licensing kept tidy

We supported a software company serving financial trading firms where we managed Microsoft 365 licensing across global offices, reviewing what was needed and keeping it tidy as people joined and left, so the firm paid for what it used rather than for forgotten seats.

For a software, technology or financial trading firm, this is part of managed IT and security that usually costs about £45 to £100 per user per month, scaling with your headcount, your security needs and how much uptime the business depends on.
