Most businesses we audit are on the wrong Microsoft 365 tier — some paying for features nobody uses, others missing security they assume they have.
Microsoft 365 plan names are unhelpful. Business Basic, Business Standard and Business Premium do not describe what separates them, and the difference matters more than the price gap suggests.
The short version
Business Basic — web and mobile Office apps only, no desktop installs. Suits staff who work in a browser.
Business Standard — adds desktop Office apps. This is where most businesses should start.
Business Premium — adds device management and advanced security. This is the one most businesses need and do not have.
The gap that catches people out
Business Standard gives you email, Office and Teams. It does not give you conditional access, device management, or the ability to wipe company data from a lost phone.
That gap becomes visible the first time an employee leaves with a personal device holding company mail, or a laptop goes missing. On Standard, your options are limited. On Premium, you can remove access remotely.
For any business handling client or personal data under India's DPDP Act 2023, that difference is not a convenience feature. It is part of being able to say you took reasonable security measures.
What businesses commonly overpay for
The opposite error is just as common. We regularly find licences assigned to staff who left months ago, users on Premium who only need email, and duplicate subscriptions bought by different departments.
A licence review usually finds enough unused seats to offset a meaningful part of an upgrade for the people who genuinely need Premium. That is a reallocation rather than new spend.
Mixed assignment is allowed and underused
You do not have to put everyone on the same plan. A common sensible pattern is Premium for anyone handling sensitive data or working on mobile devices, Standard for office-based staff, and Basic for shift or shop-floor staff who only need email.
Microsoft permits mixing tiers within one tenant, and for a fifty-person business the saving against uniform Premium is substantial.
Before you renew
Pull the sign-in activity report before your next renewal date. Any account that has not signed in for ninety days is either a leaver nobody removed or a licence nobody needs. Both are billing you monthly.

Plan choice is worth revisiting annually, because headcount and roles move faster than subscriptions do. Our Microsoft 365 service for businesses in India and Kerala covers selection and setup, and software licensing covers the wider estate if Microsoft is not your only subscription.
