Choosing the right Microsoft 365 licence is not always straightforward. Many businesses start with Microsoft 365 Business Basic because it looks like the cheapest option, then later discover they need desktop Office apps, stronger security, better device management or more control over company data.
Microsoft 365 Business Basic, Business Standard and Business Premium are all designed for small and medium-sized businesses, but they are not interchangeable. The right choice depends on how your users work, what devices they use, how much security you need and whether the business wants Microsoft 365 to be actively managed rather than simply licensed.
This guide explains the differences in plain English.
Quick comparison: Business Basic, Standard and Premium
The simplest way to think about the three main Microsoft 365 business plans is this:
- Business Basic is mainly for email, cloud storage, Teams and web/mobile Office apps.
- Business Standard adds the full desktop Office apps for users who need Word, Excel, Outlook and PowerPoint installed on their PC or Mac.
- Business Premium includes the productivity features of Standard, plus stronger security, identity protection and device management tools.
All three can be useful, but they suit different types of user.
Microsoft 365 Business Basic: best for simple cloud users
Microsoft 365 Business Basic is the entry-level business plan. It gives users business email, Microsoft Teams, OneDrive cloud storage, SharePoint and web and mobile versions of Office apps such as Word, Excel, PowerPoint and Outlook.
It is usually suitable for users who mainly work in a browser, use email, attend Teams meetings and need access to files in OneDrive or SharePoint.
Business Basic can work well for:
- Light users
- Shared or occasional users
- Users who mainly work through a web browser
- Businesses that do not need desktop Office apps
- Staff who only need email, Teams and cloud file access
However, Business Basic has an important limitation: it does not include the full installed desktop Office apps. Users can use Office apps online, but they do not get the full desktop versions of Word, Excel, Outlook and PowerPoint installed on their computer.
This can become frustrating for users who work heavily in Excel, manage large documents, rely on Outlook desktop, or need offline access to Office apps.
Microsoft 365 Business Standard: best for users who need desktop Office apps
Microsoft 365 Business Standard includes the main services in Business Basic, but adds the desktop Office apps. This means users can install Word, Excel, PowerPoint, Outlook and other Microsoft 365 apps on their PC or Mac, subject to Microsoft’s licensing terms.
Business Standard is often the right fit for office-based users who need the full Office experience.
It can work well for:
- Office staff
- Finance and accounts users
- Users who work heavily in Excel
- Users who prefer Outlook desktop
- Managers creating documents, reports and presentations
- Businesses that want familiar Office apps installed locally
For many businesses, Business Standard feels like the “normal” Microsoft 365 licence because it includes the desktop apps most people expect.
However, Business Standard is still primarily a productivity licence. It gives users the tools to work, communicate and collaborate, but it does not include the same level of advanced security and device management capability as Business Premium.
Microsoft 365 Business Premium: best for managed and security-conscious businesses
Microsoft 365 Business Premium includes the productivity tools businesses expect from Business Standard, but adds stronger security and management features. This is why it is often the better choice for businesses that want Microsoft 365 to be properly secured and managed.
Business Premium includes capabilities that can help with identity protection, endpoint security, mobile and computer management, data protection and access control.
It is often the right fit for:
- Businesses that want stronger Microsoft 365 security
- Users handling sensitive company or client data
- Businesses with laptops used outside the office
- Organisations with remote or hybrid working
- Businesses that need Conditional Access and better identity control
- Companies that want device management through Microsoft Intune
- Businesses that want a stronger foundation for cyber insurance and compliance
Business Premium is not just about having more Microsoft features. It gives the business more control over how users sign in, how devices are managed and how company data is protected.
This is why KES often recommends Microsoft 365 Business Premium for managed business users, especially where security, remote working and device control matter.
When Business Basic is enough
Business Basic can be enough for some users, especially where the requirement is simple.
It may be suitable when a user only needs:
- Business email
- Microsoft Teams
- OneDrive access
- SharePoint access
- Web-based Word, Excel and PowerPoint
- Basic collaboration tools
For example, a part-time user, warehouse user, field-based user or light admin user may not need the full desktop Office apps.
The risk is choosing Business Basic for everyone just because it is cheaper. That can create frustration later when users need proper Outlook desktop, advanced Excel features, offline work or better security controls.
When Business Standard makes sense
Business Standard makes sense when users need the full installed Office apps but the business is not yet ready to move to the stronger security and management features in Business Premium.
It is often a good fit for traditional office users who need:
- Desktop Outlook
- Desktop Word
- Desktop Excel
- Desktop PowerPoint
- Teams meetings and chat
- OneDrive and SharePoint file access
For many businesses, Business Standard is a practical productivity licence. It gives users the familiar Office tools they need every day.
However, if the business also needs stronger security, better control over laptops, Conditional Access, endpoint protection or more structured management, Business Premium is usually worth reviewing.
When Business Premium is the better choice
Business Premium is usually the better choice where Microsoft 365 is business-critical and needs to be properly secured.
It is especially relevant if:
- Staff use laptops away from the office
- Users access Microsoft 365 from multiple locations
- The business handles sensitive client or financial data
- There are cyber insurance requirements
- The business wants Conditional Access policies
- Devices need to be managed centrally
- The company wants stronger protection against compromised accounts
- The business wants a better security foundation for remote and hybrid work
For managed service customers, Business Premium often gives the right foundation because it supports a more complete security and support model. It allows Microsoft 365 to be managed as part of the wider IT environment, rather than treated as a standalone email subscription.
This is also why Business Premium fits well with the KES Business User Pack, where Microsoft 365, support, security, backup and monitoring are considered together.
The cheapest licence is not always the cheapest option
It is easy to compare Microsoft 365 plans by monthly licence cost alone. That can be misleading.
A cheaper licence may save money on the Microsoft bill, but it may also increase support time, create security gaps or require extra third-party tools to cover missing features.
For example:
- A user on Business Basic may later need desktop Office apps.
- A user on Business Standard may still need stronger security controls.
- A business using mixed licences may lose visibility of who has what.
- Old users and unused licences may continue being billed.
- Security tools may be added separately when Business Premium could have provided a better base.
The best licence is not always the lowest-cost licence. The best licence is the one that gives the user what they need while supporting the business’s security and management requirements.
Do all users need the same Microsoft 365 licence?
No. Many businesses use a mixture of Microsoft 365 licences.
For example:
- Light users may only need Business Basic.
- Office users may need Business Standard.
- Managers, finance users and laptop users may be better on Business Premium.
- Shared mailboxes may not need a paid licence at all, depending on how they are used.
- Leavers should be reviewed so licences are not wasted.
A mixed licence setup can be sensible, but it needs to be managed carefully. If it grows without review, it can become confusing and inefficient.
KES can help review Microsoft 365 licensing to check whether users are on the right plans and whether licences are being wasted.
What about Microsoft 365 backup?
Microsoft 365 licensing and Microsoft 365 backup are separate issues.
Even if your business has the right Microsoft 365 plan, you still need to consider how Exchange, OneDrive, SharePoint and Teams data is protected. Microsoft 365 includes retention and recovery features, but businesses should still make deliberate decisions about backup and monitoring.
We explain this in more detail in our guide: Why Microsoft 365 Still Needs Backup and Monitoring.
What should a business review before choosing a licence?
Before choosing or changing Microsoft 365 licences, it is worth asking:
- Does the user need desktop Office apps?
- Does the user work remotely or on a laptop?
- Does the user handle sensitive data?
- Does the business need stronger sign-in protection?
- Are devices managed properly?
- Are users already paying for overlapping third-party tools?
- Are old licences still active?
- Are shared mailboxes and leavers being handled correctly?
- Does the business need Microsoft 365 backup?
- Would a compromised account be spotted quickly?
These questions usually reveal whether the business simply needs email and Office apps, or whether it needs a more managed and secure Microsoft 365 setup.
Which Microsoft 365 plan should you choose?
As a general guide:
- Choose Business Basic for light users who mainly need email, Teams, OneDrive and web-based Office apps.
- Choose Business Standard for users who need the full desktop Office apps but do not require the extra security and device management features of Business Premium.
- Choose Business Premium for users and businesses that need stronger security, better identity protection, device management and a more complete managed Microsoft 365 setup.
For many established businesses, Business Premium is the licence that gives the best long-term foundation. It may cost more than Basic or Standard, but it can reduce risk and provide better tools for managing users, devices and data.
