UK Business Software Competition: Could Businesses Get More Choice?

UK business software competition is under closer scrutiny after the Competition and Markets Authority proposed designating Microsoft as having Strategic Market Status in its business software ecosystem. The CMA is examining whether Microsoft’s position across productivity software, operating systems, databases, security tools and related services gives it substantial influence over how UK businesses choose and combine software. The regulator is particularly interested in whether practices involving software bundling, licensing, interoperability, default settings and artificial intelligence can make it harder for customers to switch providers or use competing products alongside Microsoft software. No final Strategic Market Status decision has yet been made. However, the review raises an important practical question for businesses: how dependent is your organisation on one software supplier, and how difficult would it be to switch if prices, features or business needs changed?

What Is the CMA Microsoft Investigation UK?

The CMA Microsoft investigation UK is being carried out under the UK’s digital markets competition regime. The Competition and Markets Authority launched the investigation in May 2026 to determine whether Microsoft’s business software ecosystem should be designated as having Strategic Market Status, commonly shortened to SMS. The investigation covers a broad range of Microsoft business software, including:

• Productivity Software
• PC Operating Systems
• Server Operating Systems
• Database Management Systems
• Security Software
• Software Used Alongside Cloud Services
• AI-Enabled Business Software

The CMA is considering whether Microsoft’s position in these areas gives it substantial and entrenched market power and a position of strategic significance.

What Has the CMA Decided So Far?

The CMA has not yet made its final decision. However, on 16 October 2026, it published a proposed decision stating that its provisional view is that Microsoft meets the legal conditions for Strategic Market Status in relation to its business software ecosystem. The consultation on that proposed decision closes on: 13 November 2026 The CMA is expected to make its final decision by: 13 February 2027 This means businesses should distinguish between:

• A proposed Strategic Market Status designation
• A final Strategic Market Status designation
• Any future competition requirements imposed after designation

Microsoft has not yet been finally designated under this investigation.

What Is Microsoft Strategic Market Status UK?

Microsoft strategic market status UK would be a regulatory designation under the Digital Markets, Competition and Consumers Act 2024. Strategic Market Status does not mean that a company has broken competition law. Instead, it identifies a business that the CMA considers to have substantial and entrenched market power and a position of strategic significance in a particular digital activity. If Microsoft receives a final SMS designation, the CMA could then consider targeted rules intended to improve competition and customer choice. These measures could potentially address issues involving:

• Switching
• Interoperability
• Bundling
• Licensing
• Default Software Settings
• Access for Rival Products
• AI Integration

Any future intervention would require its own regulatory process.

Why Is the CMA Investigating Business Software?

Modern businesses often depend on interconnected software systems for everyday operations. These can include:

• Email
• Documents
• Spreadsheets
• Video Meetings
• Accounting
• Customer Relationship Management
• Cybersecurity
• Data Storage
• Cloud Computing
• Artificial Intelligence

Integration can make these tools more convenient. However, a tightly integrated software ecosystem can also make switching difficult. For example, a business may discover that replacing one application affects:

• User Accounts
• File Formats
• Security Systems
• Data Storage
• Staff Training
• Automated Workflows
• Cloud Services
• Other Connected Software

The CMA is examining whether some of these barriers unnecessarily limit customer choice.

What Are Microsoft Software Bundling Competition Concerns?

Microsoft software bundling competition concerns relate to the practice of offering several products together as part of one licence, package or subscription. Bundling can benefit customers by providing:

• Simpler Purchasing
• Integrated Software
• One Supplier Relationship
• Consistent User Management
• Easier Administration

However, competition concerns can arise if customers effectively need to buy a larger package to access particular features or if bundled products make competing software less attractive. For businesses, the practical issue is whether a bundle genuinely provides value or whether the organisation is paying for products that it does not need.

What Is Software Interoperability?

Interoperability refers to the ability of different software products and systems to communicate and work effectively together. For example, a business may want:

• One Supplier for Email
• Another Supplier for Accounting
• A Different CRM Platform
• A Separate AI Tool
• Another Cloud Provider

Strong interoperability makes this easier. Poor interoperability can create additional work, duplicated data or technical problems. The CMA is examining whether limitations in interoperability make it harder for businesses to combine software from competing providers. Businesses exploring cloud accounting Wimbledon services can assess how well their accounting platforms integrate with banking systems, reporting tools and other business software.

Why Does Interoperability Matter to Businesses?

Poor interoperability can create hidden costs. A cheaper competing application may appear attractive until the business discovers that moving to it requires:

• Custom Integrations
• Manual Data Transfer
• New Security Processes
• Employee Retraining
• Changes to Existing Workflows
• Additional Software Connectors

These costs can discourage businesses from switching even where a competing product offers better functionality or pricing. Businesses should therefore evaluate both the subscription price and the total cost of switching.

What Is Software Vendor Lock-In?

Software vendor lock-in occurs when switching away from a supplier becomes unusually difficult, expensive or disruptive. A business might experience vendor lock-in because:

• Data Is Difficult to Export
• File Formats Are Proprietary
• Other Systems Depend on the Supplier
• Staff Are Heavily Trained on One Platform
• Integrations Are Difficult to Replace
• Long Contracts Apply
• Discounts Depend on Bundled Products

Vendor lock-in does not necessarily mean the original software choice was poor. Integrated platforms can provide significant benefits. The risk arises when the business loses practical flexibility.

How Can Businesses Measure Software Dependence?

Businesses should periodically map which software systems are essential to their operations. A useful review can ask:

1. Which Systems Are Business-Critical?
2. Which Supplier Provides Each System?
3. What Data Does Each Platform Hold?
4. Can That Data Be Exported?
5. Which Other Systems Depend on It?
6. How Long Would Migration Take?
7. What Would Switching Cost?
8. Are Staff Skills Tied to One Platform?
9. Are Contracts Easy to Exit?
10. Are Viable Alternatives Available?

This helps management understand whether convenience has gradually developed into dependency.

Why Is AI Part of the CMA Investigation?

Artificial intelligence is becoming increasingly embedded in mainstream business software. AI tools can now appear within:

• Email Platforms
• Office Software
• CRM Systems
• Data Analytics
• Security Software
• Cloud Platforms
• Communication Tools

The CMA is interested in whether competing AI products can integrate fairly with major business software ecosystems. This matters because the way AI is integrated today could influence which providers businesses are able to use in future. If one software ecosystem becomes the default route through which businesses access AI tools, switching barriers could become even more important.

Could AI Bundling Reduce Customer Choice?

Potentially. AI features included automatically in larger software packages may be convenient, but businesses should still consider whether those tools provide the best value. Questions to ask include:

• Is the AI Feature Actually Being Used?
• Is It Included or Charged Separately?
• Can Competing AI Tools Access the Same Business Data?
• Can Employees Use Alternative AI Products?
• Does Switching Require Moving Other Software?
• Are Security and Data Controls Different?

The objective is not necessarily to avoid integrated AI. It is to understand whether integration is creating unnecessary long-term dependency.

Could Strategic Market Status Reduce Software Lock-In?

Potentially, but no specific outcome is guaranteed. If Microsoft receives final Strategic Market Status, the CMA could consider targeted interventions intended to improve customer choice. Possible areas identified for further investigation include:

• Easier Switching
• Better Interoperability
• Licensing Changes
• Bundling Practices
• Default Settings
• Rival AI Access

The precise measures would depend on further evidence and consultation. Businesses should therefore not assume that a final designation would immediately change their software contracts or licence terms.

Is the CMA Investigating Microsoft Cloud Licensing?

Microsoft’s software licensing has also been part of wider UK competition concerns involving cloud services. Previous CMA work identified concerns that licensing arrangements for major Microsoft software products could influence customers’ ability to use competing cloud infrastructure providers. The CMA has been working separately with Microsoft and Amazon Web Services on cloud competition issues. The business software investigation creates another regulatory route through which software licensing and customer choice can be considered.

What Does This Mean for Small Businesses?

Small businesses may be particularly exposed to software dependency because they often have limited internal IT resources. A small company may gradually build its operations around one provider because it is easier to manage. Over time, that ecosystem might include:

• Email
• Documents
• File Storage
• Meetings
• Security
• CRM
• Reporting
• AI Tools

Switching several systems at once can then become expensive. Small businesses should therefore consider software flexibility before dependency becomes difficult to reverse.

Should Businesses Stop Using Integrated Software Suites?

No. Integrated software can offer substantial benefits. These can include:

• Easier Administration
• Faster Staff Onboarding
• Better Data Sharing
• Centralised Security
• Fewer Compatibility Problems
• Lower IT Support Costs
• Simplified Billing

The issue is not whether integrated software is inherently bad. The better question is whether the business remains able to change supplier if circumstances change.

How Can Businesses Reduce Software Lock-In?

Businesses can take several practical steps.

Check Data Portability

Make sure important business data can be exported in commonly usable formats.

Review Integrations

Identify which systems depend on each other and whether alternative applications could connect to them.

Avoid Unnecessary Bundling

Check whether the business is paying for bundled software that employees rarely use.

Review Contracts

Understand:

• Renewal Dates
• Notice Periods
• Minimum Contract Lengths
• Price Increase Clauses
• Data Export Terms

Maintain Independent Backups

Critical business data should not rely entirely on access to one software platform.

Test Alternatives

Businesses do not need to migrate immediately, but understanding available alternatives can improve negotiating power. Businesses seeking digital accounting Fulham services can review whether their current accounting software supports data portability, integration with other platforms and flexibility when changing providers.

How Often Should Businesses Review Software Costs?

A software review can be carried out at least annually and before major contract renewals. The review should consider:

• Monthly Subscription Costs
• Annual Subscription Costs
• Number of Active Users
• Unused Licences
• Duplicate Software
• Recent Price Increases
• Alternative Suppliers
• Migration Costs
• Integration Costs

Software costs can gradually increase because subscriptions are often spread across departments and paid automatically. A central software register can help management identify unnecessary expenditure. Businesses reviewing software subscriptions and digital systems may benefit from professional digital accounting services in Wimbledon  when assessing accounting software costs, integrations, reporting processes and the financial impact of changing platforms.

What Is a Software Audit?

A software audit is a structured review of the applications and subscriptions used by a business. A basic audit can record:

Area	What to Review
Software	Product and provider
Users	Number of active licences
Cost	Monthly or annual charge
Purpose	Business function
Data	Information stored
Integration	Systems connected
Contract	Renewal and termination terms
Alternative	Other suitable providers
Dependency	Difficulty of switching

The objective is to understand both software cost and operational dependence.

How Can Software Choice Affect Business Costs?

Software competition affects businesses financially in several ways. Costs can include:

• Subscription Fees
• Licence Fees
• Implementation
• Training
• Integration
• Migration
• Consulting
• Data Storage
• Security
• Support

A low headline subscription price can therefore be misleading if switching or integration costs are high. Businesses should consider total software cost over several years rather than only the monthly licence price. A digital transformation accounting approach can help businesses evaluate the financial impact of adopting new software, improving integrations and reducing unnecessary technology expenditure.

Could Better Software Competition Help UK Businesses?

Potentially. Stronger competition can give businesses more options over pricing, functionality and suppliers. Potential benefits can include:

• More Product Choice
• Greater Pricing Pressure
• Better Interoperability
• Easier Switching
• More Innovation
• Better Access to Competing AI Tools

However, any practical benefits from the CMA investigation will depend on the final Strategic Market Status decision and whether future regulatory measures are introduced.

What Should Businesses Do Before Software Contracts Renew?

Businesses approaching a renewal should consider:

1. Review Current Usage
2. Remove Unused Licences
3. Compare Alternative Providers
4. Check Data Export Options
5. Review Integration Dependencies
6. Calculate Migration Costs
7. Check Contract Notice Periods
8. Review Security Requirements
9. Compare AI Features
10. Negotiate Before Renewing

Renewal is often the best time to reconsider whether the current software structure still suits the business.

Review Software Dependence Before It Becomes a Business Risk

The UK business software competition review highlights a wider issue for businesses that extends beyond Microsoft. Integrated software can make operations easier, but it can also create dependency. Businesses should understand:

• Which Supplier Controls Critical Systems
• Whether Business Data Can Be Exported
• Whether Alternative Software Can Integrate
• How Much Switching Would Cost
• Whether Bundled Products Are Actually Used
• How Contract Terms Affect Flexibility
• Whether AI Tools Can Be Changed Independently

The CMA’s proposed Microsoft strategic market status UK decision could eventually lead to measures designed to increase customer choice. Businesses do not need to wait for the regulatory process to finish before reviewing their own software position. Regular software audits, better control of subscriptions and clear data-export arrangements can help businesses manage costs and preserve flexibility as technology continues to change. CIGMA Accounting can help businesses assess software costs, digital accounting systems, technology-related operating expenses and the financial impact of changing business software. As a tech-forward accounting firm, CIGMA Accounting can help businesses assess cloud accounting solutions, software compatibility and the financial implications of adopting alternative digital platforms.

CASE STUDY: UK Business Software Competition and Reducing Software Vendor Lock-In

Daniel, a small business owner, visited our Farringdon office while reviewing his company’s software subscriptions ahead of their annual renewal. His business relied on one software provider for email, document management, cloud storage and communication tools, but increasing licence costs had prompted him to consider alternatives. Daniel was particularly interested in the CMA Microsoft investigation UK and whether proposed changes to UK business software competition could provide businesses with greater flexibility. We explained that the Competition and Markets Authority had proposed giving Microsoft Strategic Market Status, but no final decision had been made. Any future changes to software bundling, licensing or interoperability would require further regulatory action. During the review, we examined the company’s software expenditure:

• Annual software subscription costs: £18,000
• Unused and duplicated licences: £3,000
• Potential annual saving from removing unnecessary licences: £3,000

We also discussed software vendor lock-in, including the potential costs of migrating business data, retraining employees and replacing existing integrations. Because Daniel used separate accounting and reporting software, we considered how software interoperability could affect financial reporting, bookkeeping efficiency and future digital accounting requirements. Daniel decided to remove unused licences, review contract renewal terms and assess data-export options before switching providers. He left understanding that improving software choice is not simply about finding cheaper subscriptions. Managing total software costs, maintaining data portability and reducing unnecessary supplier dependency are equally important.
