Only 5.0% of US IT providers name Microsoft 365 as a service.
Microsoft 365 sits on more small-business desktops than any other platform, yet 1,973 of 39,722 US providers name it. The ones that do carry double the reviews of the typical provider.
of 39,722 US providers name Microsoft 365 among the services they offer
n = 39,722 published US providers, of which 1,973 name Microsoft 365, Office 365, M365 or O365 among the services they offer. Services are on file for 35,759 of the 39,722, so an unknown counts against the share and 5.0% is a floor. Shares labeled "of the Microsoft 365 group" are against those 1,973.

The published statistic behind this
Microsoft platforms dominate the IT provider vendor stack: 5,642 firms name Microsoft 365 and 3,982 name Azure.
n = 19,044 providers with a vendor stack on file · measured 2026-09-17. The figures on this page are frozen at their own measurement date and are not recomputed from that table.
Vendor stack prevalence ▸The most common platform is one of the least advertised services
1,973 of 39,722 published US providers name Microsoft 365 among their services — 5.0%. Services are on file for 35,759 firms, so this is not a coverage artifact: among providers whose service list we can read at all, 94.5% never name the platform their clients open every morning.
A further 313 providers name Azure, SharePoint, Intune or Dynamics 365 without naming Microsoft 365 itself, which brings the wider Microsoft-naming group to 2,286 firms, or 5.8% of the directory.
The likely explanation is that Microsoft 365 administration is treated as table stakes rather than a service line — something bundled inside "managed IT" and never itemized. That is a marketing choice with a search consequence: a buyer typing the platform name into Google is not shown the 37,749 providers who do the work but never say so.
The firms that do name it are more visible than average
The median Microsoft 365 provider that has any Google rating carries 14 reviews, against a directory median of 7. That is double, and it is the widest review gap of any service group measured on this site.
They are also more likely to be found at all: 1,142 of the 1,973, or 57.9%, show a Google rating, against 43.8% directory-wide. Headcount barely moves — a median of 10 staff over the 1,518 that publish one, against a directory median of 9 — so this is not a size effect. It is a visibility effect.
Naming the platform travels with naming everything else. 1,446 of the group, or 73.3%, also name a security service, and 1,155, or 58.5%, name backup or disaster recovery. Providers that itemize one service tend to itemize the rest.
Credentials are the weak point
444 of the 1,973 show a certification of any kind — 22.5%, better than the directory's 15.6% and still a minority. 1,529 providers who advertise Microsoft 365 management show a buyer no third-party credential at all.
No Microsoft partner designation or Microsoft certification appears anywhere in the credentials recorded on this site, for any provider in the directory. That is a limit of what this site collects rather than a finding about the market, and it is the reason the certification share above is a general one and not a Microsoft-specific one.
750 of the group, or 38.0%, also name healthcare among their verticals, the largest vertical overlap in the set. Only 42 of the 1,973 publish a per-user, per-month rate, at 2.1% of the group — too few to give a Microsoft 365 pricing benchmark, so none is given here.
What this number can't tell you
- ·This measures what providers publish about themselves, not what they operate. A provider administering Microsoft 365 for every client who never names it is counted in the 95.0%.
- ·Services are on file for 35,759 of the 39,722 published firms, so 5.0% is a floor and an unknown counts against it.
- ·Service tags are matched as stored tokens, not as free text. The group is every firm carrying a tag containing microsoft_365, office_365, m365 or o365. A provider describing the work only in prose on its own site is not counted.
- ·The wider Microsoft group adds Azure, SharePoint, Intune, Dynamics 365 and hosted Exchange tags. Tags for office relocation, office setup, virtual office and back-office work are excluded by name, because a plain match on "office" pulls them in.
- ·No Microsoft certification or partner tier is recorded for any provider in this directory. The 22.5% certification share counts credentials of any kind, not Microsoft ones, and no Microsoft-specific credential claim can be made from this data.
- ·Median headcount is over the 1,518 firms in the group that publish one, and self-published headcounts are not audited.
- ·Review medians are over rated firms only. Rating values themselves are not plotted: google_rating bunches at the top of its range and a percentile of it would mislead.
- ·State counts are provider headquarters, not service areas.
- ·No pricing figure is given: only 42 firms in this group publish a per-user, per-month rate, and a median over 42 firms would describe those 42 rather than the group.
What to do about it
- ▸Buying: naming Microsoft 365 is a weak signal of capability but a strong signal of transparency — the 5.0% who itemize it also itemize security and backup far more often than the rest. Ask any provider who does not name it whether tenant administration, license management and Entra configuration are inside the monthly fee or billed as projects.
- ▸Selling: this is the widest open gap in the directory. 94.5% of providers whose services we can read never name the platform, and the ones who do carry twice the reviews of the typical firm. Itemizing Microsoft 365 as a named service line costs nothing and puts a provider in a field of under two thousand rather than forty thousand.
