Microsoft 365 Licensing: Are You Paying for the Right Licence?

For many businesses, Microsoft 365 has become as essential as electricity and internet connectivity. Employees rely on it every day to send emails, collaborate through Microsoft Teams, store files in OneDrive and SharePoint and run critical business applications.

But despite its importance, Microsoft 365 licensing is often something that’s set up once and then forgotten about.

A business purchases licences when it first adopts Microsoft 365, employees are assigned licences as they join the company and years later nobody has stopped to ask whether those licences are still the right fit.

The result? Many organisations either pay for functionality they don’t use, miss out on valuable features they could benefit from or find themselves operating with licences that no longer reflect how the business works today.

In this guide, our experts will explain the different Microsoft 365 business licences, highlight common licensing mistakes and show how a licensing review can help your organisation improve security, productivity and value.

Why Microsoft 365 Licensing Isn't as Simple as It Seems

Most people assume Microsoft licensing is straightforward.
If employees can send emails, access Word and Excel, join Teams meetings and share files, everything must be working correctly.

Unfortunately, that’s not always the case.

Over the years, we’ve worked with businesses that were paying for advanced functionality nobody was using. We’ve also seen organisations operating with licences that lacked important security features, leaving them unnecessarily exposed to cyber threats.

The challenge is that Microsoft 365 has evolved significantly. What may have been the right licence three years ago may no longer be the best fit today.

As businesses grow, adopt hybrid working, strengthen cybersecurity measures or introduce new compliance requirements, their licensing needs often change too.

Common Microsoft 365 Licensing Mistakes

Many licensing issues go unnoticed until a business reviews its costs, security settings or user requirements.

Some of the most common problems include:

Paying for Features Nobody Uses

Many organisations purchase premium licences across the entire workforce, despite only a small percentage of employees needing the advanced functionality included.

Without regular reviews, businesses can end up paying for services that deliver little real value.

Choosing Licences Based on Cost Alone

While controlling costs is important, selecting the cheapest licence isn’t always the most cost-effective decision.

Lower-priced plans may lack essential security controls, compliance tools, device management capabilities and productivity features that could save time, reduce risk and improve operational efficiency.

Using Consumer Licences in Business Environments

We’ve encountered organisations using Microsoft 365 Personal or Family subscriptions for business purposes. These plans lack the management, security and administrative controls required in a professional environment.

Failing to Review Licensing as the Business Evolves

Businesses change constantly. Staffing levels fluctuate, working practices evolve and security requirements increase.

What was once the perfect licensing setup may no longer support the organisation’s current needs.

Understanding the Different Microsoft 365 Business Licences

Microsoft offers several business-focused licensing options, each providing different levels of functionality, security and management capabilities.

What Do You Actually Get with Microsoft 365?

Many businesses still view Microsoft 365 as simply Word, Excel and Outlook.

In reality, it offers much more.

Depending on your licence, Microsoft 365 can include:

Microsoft Teams collaboration
OneDrive cloud storage
SharePoint document management
Email security and threat protection
Device management through Intune
Identity and access controls
Compliance and governance tools
Secure remote working capabilities
Webinar and productivity solutions

These tools can help businesses improve productivity, strengthen security and support hybrid working environments.

Understanding How Your Employees Actually Work

One of the most effective ways to assess Microsoft licensing is to understand how employees use the platform day to day.

Some users spend most of their time in Outlook and Teams. Others rely heavily on desktop applications such as Excel, Word and PowerPoint. Certain employees may require advanced security protections because of the data they handle, while others simply need access to email and shared files.

This is why assigning the same licence to every employee isn’t always the most effective approach.

By reviewing user requirements, application usage and security needs, businesses can often create a licensing strategy that delivers better value while improving functionality.

Choosing the Right Commercial Model

Selecting the right Microsoft licence is only part of the equation.

Businesses should also consider how those licences are purchased.

Microsoft offers several commitment models designed to balance flexibility and cost:

Annual Commitment (Paid Upfront)

Often provides the best commercial value for organisations with stable staffing levels and predictable growth.

Annual Commitment (Monthly Billing)

Allows businesses to spread costs throughout the year while still benefiting from competitive pricing.

Monthly Commitment

Ideal for organisations that rely on temporary workers, contractors or seasonal staff, allowing licence quantities to scale up or down as requirements change.

Choosing the right purchasing model can be just as important as selecting the right licence itself.

Why Regular Licensing Reviews Matter

It isn’t uncommon for organisations to continue using the same Microsoft 365 licences year after year without reviewing whether they remain suitable.

However, business requirements rarely stand still.

A licensing review can help identify:

Unused licences and wasted expenditure
Security gaps and compliance risks
Opportunities to improve productivity
More suitable licence options
Better commercial purchasing models

In many cases, businesses discover they can either reduce costs, improve security or unlock functionality they didn’t realise they already owned.

Not Sure if Your Licensing Is Right?

If your Microsoft 365 licensing hasn’t been reviewed in the last 12 months, there’s a good chance your business requirements have changed.

A licensing review can provide clarity, helping you understand whether your current setup remains fit for purpose and whether there are opportunities to improve value.

FAQs

How do I know if I have the right Microsoft 365 licence?

The best way to find out is through a Microsoft 365 licensing review. Many businesses continue using the same licences for years without checking whether they still meet their needs. A review can identify unused features, security gaps and opportunities to reduce costs.

What is the most commonly used Microsoft 365 licence for businesses?

Microsoft 365 Business Standard is one of the most popular licences because it combines professional email, Microsoft Teams, OneDrive, SharePoint and the desktop Office applications. However, the most suitable licence depends on how your employees work and what security features your organisation requires.

What is the difference between Microsoft 365 Business Basic and Business Standard?

Microsoft 365 Business Basic includes business email, Teams, OneDrive, SharePoint and web-based Office applications. Business Standard includes everything in Business Basic, plus the desktop versions of Word, Excel, Outlook and PowerPoint.

Is Microsoft 365 Business Premium worth the extra cost?

For many organisations, yes. Business Premium includes advanced cybersecurity, device management and identity protection features that can significantly improve your security posture. However, not every user requires these capabilities, which is why a licensing review is important.

Can I use different Microsoft 365 licences for different employees?

Yes. Many businesses use a mix of Microsoft 365 licences across their organisation. For example, some employees may only require Business Basic, while others benefit from Business Premium because of their role, responsibilities or security requirements.

Can a Microsoft 365 licensing review save money?

Absolutely. It is common for businesses to discover they are paying for licences with features that are never used, or that they are using higher-tier licences where a lower-cost alternative would be more suitable.

How often should Microsoft 365 licences be reviewed?

We recommend reviewing Microsoft 365 licensing at least once a year. It’s also worth carrying out a review after significant business changes such as growth, acquisitions, staffing changes or the introduction of new security requirements.

What happens if my business grows during a Microsoft 365 commitment period?

Additional licences can usually be added at any time. The options available will depend on your chosen commitment model and billing arrangement. Birmingham Telecom can help ensure you remain on the most suitable commercial plan as your business evolves.

Which Microsoft 365 commitment option is best?

There is no single answer. Businesses with stable staffing levels often benefit from annual commitments, while organisations that employ contractors or experience seasonal fluctuations may prefer the flexibility of monthly licensing. The right option depends on your commercial and operational requirements.

Can Birmingham Telecom manage our Microsoft 365 licences?

Yes. Birmingham Telecom can help review, procure, manage and optimise Microsoft 365 licences whilst providing ongoing support, security guidance and advice as your business grows.

Do Birmingham Telecom charge for a Microsoft 365 licensing review?

We offer a no-obligation Microsoft 365 licensing review, helping businesses understand whether they are correctly licensed and whether there are opportunities to improve security, productivity or reduce costs.
