How a 20 person accounting firm cut roughly 2,000 dollars a year of wasted Microsoft 365 licenses

In a single 15 minute review, we found the licenses this firm was paying for but nobody used. We removed them with sign off, so the savings showed up on the very next bill.

The Challenge

Quietly overpaying Microsoft every month, and nobody had noticed

This 20 person accounting firm was paying more to Microsoft than it should, and the invoice never gave it away. Each line item looked small, so for years it simply got paid. The bill kept going out and the work kept getting done. The waste sat there in plain sight.

The owner sensed the Microsoft 365 spend was high but had no easy way to prove it. There was no clear map of who used what, and no time to dig through the admin center line by line. They wanted a straight answer, not a sales pitch.

Paying for people who had leftPaid licenses were still assigned to employees gone for months.
Full licenses on shared inboxesinfo@ and sales@ were licensed accounts that need no license at all.
Premium plans nobody neededHigher tiers were in place where a smaller plan covered the work.
Two ecosystems doing one jobThe firm was funding two overlapping platforms for the same work.

The waste was never hiding. It was just never questioned. Each small line item kept getting paid because no one had the time to add them up.

What They Needed

  • A clear picture of what they pay now versus what they should pay

Our Approach

Counted the licenses against real people, live and on screen

Free 15 minute review, on screen with them

We opened the Microsoft 365 admin center together and counted paid licenses against actual people. The waste showed up live while they watched. No long audit required.

Found the dead accounts

Paid licenses were still assigned to employees who had left months earlier. Money was going out every month for people who were gone.

Fixed the shared mailboxes

Full paid licenses were sitting on shared mailboxes like info@ and sales@. Those mailboxes need no license at all to keep working.

Right sized the plans

Premium plans were in place where a smaller plan covered everything the team used. We matched each plan to real usage.

Called out the double paying, then executed with sign off

The firm was paying for two ecosystems doing one job. We gave an honest recommendation to consolidate, even though it meant a smaller project for us. Nothing was removed without their approval. We cleaned up only what they confirmed.

The savings on screen

The bill before, the right sized plan after

Same firm, same people doing the same work. The only change is that every paid license now maps to someone who needs it. The waste came off, and the things the team relies on stayed exactly where they were. The lower number landed on the next invoice.

Most tenants carry waste like this. We are 100 percent Microsoft native and make money on expertise, not on reselling licenses. Our only incentive is your bill going down.

What We Delivered

A spend that finally makes sense, in plain language

A license map

Every paid license matched to a named person, so the spend finally made sense at a glance.

A short written summary

What they pay now, what they should pay, and the difference per year, in plain language they could act on.

Shared mailboxes done right

info@ and sales@ converted to their free, unlicensed form, so the addresses kept working at no cost.

An honest recommendation

No upsell, no jargon. Just the move that lowers the bill, including the consolidation to a single platform.

Common Questions

What people ask about this kind of project

How can you find savings in just 15 minutes?

We open your admin center with you and count paid licenses against real people. Dead accounts, licensed shared mailboxes, and oversized plans show up fast, often live while you watch.

Will removing licenses break anything or lose data?

No. Nothing is removed without your sign off. Shared mailboxes keep working in their free form, and we never touch a license until you confirm the person no longer needs it.

We pay for both Google and Microsoft. Can you help us pick one?

Yes. We give you an honest recommendation on consolidating to one platform, even when the honest answer means a smaller project for us. The goal is a lower bill, not a bigger sale.

Keeping It Clean

One review now, and the waste stays off

License waste creeps back. People leave, plans change, and new line items quietly appear. With an ongoing Microsoft 365 managed support retainer, we watch the tenant month to month. The spend you just cleaned up will not slowly fill back up. One honest review now, and a steady hand on it after.
