Microsoft 365 License Optimization Service

Our Microsoft 365 license optimization service right sizes the single largest line item in most software budgets. We map every user to the tier they actually use, clear inactive seats, and strip add on overlap, so you pay for the Microsoft 365 capability your people rely on and nothing more.

Microsoft 365 is usually the biggest software cost a mid market company carries, and it is also where the most waste hides. Premium tiers get assigned by default. Add ons stack up. Seats stay live long after people leave. Our Microsoft 365 license optimization service finds all of it and recovers the spend, without removing anything your active users depend on.

We are independent and buyer side. We take no vendor commission and are paid only by the buyer, so the recommendations follow your usage and your interests, never a reseller margin.

What the Microsoft 365 license optimization service covers

The work targets the specific places Microsoft 365 spend leaks in mid market estates.

E3 and E5 tier fit

The classic overspend is paying for E5 where E3 would do. E5 bundles advanced security, compliance and analytics that many users never touch. We measure which premium features are actually used and downgrade the seats that do not need them. As of June 2026, Microsoft publishes its Microsoft 365 enterprise plan lineup and feature comparison on its official plans page, and tiers and inclusions change often, so we anchor every recommendation to the current published plan and an as of date.

Add on overlap

Standalone add ons frequently duplicate capability already inside a tier the user holds. We map the add ons against the base plan and remove the ones that pay twice for the same function.

Inactive and duplicate seats

We pull sign in and activity data to find seats with no meaningful use, then reclaim them. Leavers, duplicate accounts and never adopted licenses are the fastest recovery in the estate.

Frontline and mixed plans

Not every worker needs a full knowledge worker license. Frontline F1 and F3 plans fit deskless and shift staff at a lower cost. We mix plans to the workforce rather than buying one tier for everyone.

How the service works

Assess

We build a true usage picture across the tenant: who holds what license, at which tier, with which add ons, and how each is actually used.

Right size

We quantify the recoverable spend from downgrades, reclamation and add on removal, then sequence the changes to land at the right contract moments rather than getting trapped behind commitment terms.

Govern

We put a joiner and leaver process and periodic license reviews in place so the savings hold through the next true up rather than creeping back.

Where this fits in the wider stack

Microsoft 365 is the largest single opportunity, but the real prize is the whole estate. This service feeds directly into the flagship digital workplace cost optimization program, which looks at every vendor at once. Go deeper with the Microsoft 365 optimization pillar, and pair this work with our license right sizing and reclamation service for the same discipline applied across the rest of your tools.

When the renewal lands, our SaaS renewal negotiation method turns the lower seat count into a permanently lower contract.

Frequently asked questions

How much can a Microsoft 365 license optimization service save?

It depends on your tenant, but E5 to E3 downgrades, add on removal and inactive seat reclamation are common sources of recovery in mid market estates. We size the saving against your own usage data before any change.

Will downgrading E5 to E3 remove features people use?

No. We only downgrade seats where the E5 premium features show no meaningful use. Users who rely on advanced security, compliance or analytics keep E5. The point is to stop paying premium for capability nobody touches.

How do you decide which add ons to remove?

We map each add on against the base plan the user already holds and against actual usage. Add ons that duplicate included capability or sit unused are candidates for removal.

Is this service independent of Microsoft?

Yes. We are buyer side only, take no vendor commission and are paid only by the buyer. We are not a reseller, so there is no margin steering the advice.

Do you handle the Enterprise Agreement true up?

Yes. We time right sizing around the EA true up and renewal so the lower baseline locks in rather than being clawed back. For contract interpretation we recommend you also use your own counsel.

How does this connect to the rest of our software spend?

Microsoft 365 is usually the largest line item, so it is the natural starting point, but it links up into a full stack engagement that rationalizes collaboration tools, content platforms and renewals across the whole digital workplace.
