Microsoft 365 Renewal: What Small Businesses Should Check

A software renewal can look like a routine expense. The team knows the system, documents are already stored there and changing anything feels like another job nobody has time to manage.

But before renewing Microsoft 365 or adding more AI subscriptions, it is worth asking what your business actually uses, what it depends on and what the full commitment will cost.

Staying with the same supplier can be the right decision. It should be a decision you have assessed, rather than one made by a renewal date passing unnoticed.

What the CMA announcement means

On 16 October 2026, the Competition and Markets Authority proposed designating Microsoft with strategic market status in its business software ecosystem. The CMA says those products serve over one million UK businesses and public sector organisations, with around 20 million monthly users. Those figures cover organisations collectively, not small businesses alone.

The accompanying roadmap identifies further work on cloud licensing, AI functionality, communication and collaboration applications, and security software. It makes clear that the proposed designation does not establish or assume wrongdoing.

This remains a proposal. The consultation closes at 5pm on 13 November 2026, with a final designation decision due by 13 February 2027. Possible interventions would require further assessment and consultation.

According to Reuters’ reporting, Microsoft disputes the CMA’s assessment and says its products can operate alongside competing services.

Your current agreement still matters

The announcement does not introduce an immediate price reduction or a new right to cancel your subscription. It is a reason to understand your purchasing decisions, rather than assume your current terms have changed.

Check the agreement you actually have. If you buy through a reseller or IT provider, establish who manages the renewal and what notice is required. Ask them to explain the commitment period, billing arrangements and any restrictions on changing licence numbers.

A monthly payment is not enough information to tell you how long you are committed. Record the contractual details before comparing options.

Start with one subscription register

Create a single record of the software your business pays for. For each product, note:

• The person responsible for the account and renewal.
• The number of paid licences and who uses them.
• The renewal date and any notice deadline.
• The price and total commitment over the contract period.
• The business tasks it supports.
• Any connected systems that rely on it.

Include separate subscriptions that overlap with features in your main package. A business might pay for document storage, meeting software and an AI assistant through different accounts without ever reviewing the combined arrangement.

Overlap is a prompt to investigate, not proof that one service should be cancelled. A separate tool may serve a specific customer requirement or work better for a particular task.

Find out what the team actually uses

Ask people to explain how they complete essential work: handling enquiries, preparing proposals, delivering services, recording information and sending invoices.

Which tools help? Where is information copied manually? Which features are rarely opened? Where does work stop because only one person understands the system?

This is where a review of business processes becomes useful. The aim is to connect spending with the way work gets done.

Usage alone does not tell the whole story. A security or recovery function may be essential even if staff never open it. Check with the person responsible for IT before removing licences, permissions or services that protect information or support other systems.

Compare the complete cost of staying or switching

A cheaper subscription can become expensive if it creates extra administration. A familiar package can also be poor value when the business keeps paying for unused capacity.

Compare three realistic choices: keep the current arrangement, simplify it, or change selected tools. Include setup, staff training, data migration, support and potential disruption alongside the subscription price.

Ask what would happen to shared files, customer communications, templates and connected applications. If moving a tool means rebuilding several processes, that work belongs in the comparison.

Integrated software can offer genuine benefits through consistent access, familiar interfaces and fewer systems to administer. Several separate products may give you more choice while creating more responsibility for connecting and maintaining them. Neither approach is automatically better.

As with any small business investment decision, the useful measure is whether the change improves the operation enough to justify its full cost.

Test AI spending against a specific task

Before adding AI subscriptions across the team, choose one repeatable task and define what a useful result would look like.

For example, you could test drafting a standard internal document using approved information. Compare the time taken to produce, check and correct the result with the existing process. Include checking time in the assessment: a fast first draft is not the same as a finished piece of work.

Record whether quality improves, stays consistent or becomes harder to control. Use information permitted by your organisation’s data handling arrangements, and check the tool’s suitability before entering confidential material.

A small, controlled trial gives you a better purchasing basis than assuming an additional feature will automatically make everyone more productive.

Understand how essential information can move

Ask your IT provider to explain which information you can export, the formats available and what would be needed to use it elsewhere. Establish who controls administrator access, how permissions are managed and how important records would be recovered.

A successful file download does not prove that an entire workflow can move intact. Shared links, access permissions, automations and integrations may need separate attention.

Use a controlled test with suitable sample information. Do not disrupt a live customer process simply to find out whether an alternative works.

Choose what to renew, simplify or investigate

Give the review a named owner and complete it before the relevant notice deadline. Keep a short written record of the decision, the reasons and what will be reviewed next time.

Before committing to another year of software, understand which parts your business depends on and what value they deliver. You do not need to change suppliers to demonstrate good management. You need to know why the arrangement you choose makes sense.

The most useful outcome may be fewer licences, a better process, a limited trial or a confident decision to renew. The important part is that the business has made that choice deliberately.
