What Is a Software Audit and Why Does Your Business Need One?

Most businesses accumulate software the way offices accumulate stationery, gradually, inconsistently, and with little record of where it all went. A tool purchased for one project stays installed long after the project ends. A subscription renews quietly each month. A free download from three years ago sits on a company device with no one quite sure what it does.

None of this feels urgent - until it is. A software audit is how businesses get clear on exactly what they have, what they are paying for, and what risks are sitting quietly in the background.

What Is a Software Audit?

A software audit is a systematic review of all software installed and in use across an organisation's devices and systems. It examines what software is present, whether it is properly licensed, whether it is up to date, and whether it aligns with the organisation's current security and operational requirements.

The term covers two related but distinct scenarios:

• An internal audit - conducted proactively by your business or an external IT partner, designed to give you visibility and control over your software environment.
• A vendor or publisher audit - initiated by a software vendor (such as Microsoft, Adobe, or Oracle) to verify that your organisation's usage complies with the terms of your licensing agreements.

Both matter, but the internal audit is the one entirely within your control - and the one that prepares you for everything else.

According to ISACA, a global association for IT governance professionals, software audits fall under the broader discipline of IT asset management (ITAM), which is the process of ensuring an organisation's assets - including software - are accounted for, deployed correctly, maintained, and disposed of when no longer needed. The international standard governing this discipline is ISO/IEC 19770, which sets the benchmark for software asset management worldwide.

What Does a Software Audit Actually Involve?

A thorough software audit typically covers the following areas:

1. Software Discovery and Inventory

Every piece of software installed across company devices - including laptops, desktops, servers, and mobile devices - is identified and recorded. This includes operating systems, productivity suites, industry-specific applications, plugins, and browser extensions.

2. License Verification

Each application is checked against your organisation's purchasing records to confirm that valid, current licenses are in place. This includes checking license types (per user, per device, concurrent, subscription) and ensuring usage does not exceed what has been purchased.

3. Security and Patch Status Review

Software that is outdated or no longer supported by its vendor represents a security vulnerability. The audit identifies applications that have not received security updates, as well as software that has reached end-of-life status.

4. Redundancy and Overlap Review

Businesses often pay for multiple tools that perform the same function. An audit surfaces this overlap, creating opportunities to consolidate and reduce costs.

5. Compliance Assessment

The findings are reviewed against relevant licensing agreements, internal IT policies, and applicable regulatory requirements to identify any areas of non-compliance or risk.

Why Does Your Business Need One?

Licensing Compliance Is a Legal and Financial Obligation

Using software beyond the terms of its license agreement is a breach of contract and, in many jurisdictions, a breach of copyright law. The BSA | The Software Alliance, which represents major software publishers globally, conducts compliance programmes in various markets and has consistently reported that software asset management gaps are widespread across businesses of all sizes. Enforcement actions, where they occur, can result in significant financial penalties and reputational damage.

An internal audit conducted before a vendor approaches you is a far more controlled and cost-effective position to be in.

Unused Software Is a Budget Problem

Software subscriptions that renew automatically, licenses purchased for employees who have since left, and tools that were trialled but never formally cancelled all represent direct, unnecessary expenditure. For organisations managing dozens or hundreds of applications, this waste can be substantial. A software audit gives finance and operations leadership the data needed to make informed decisions about renewals and consolidation.

Outdated Software Is a Security Risk

NIST (the US National Institute of Standards and Technology) identifies unpatched and unsupported software as a significant attack surface in its cybersecurity guidance. Software that no longer receives security updates from its vendor cannot be defended against newly discovered vulnerabilities. An audit makes these exposures visible so they can be addressed before they become incidents.

It Supports Broader IT and Business Governance

For businesses operating under regulatory frameworks - whether that is data protection legislation, industry-specific compliance requirements, or internal governance standards - a documented software audit provides evidence of due diligence. It demonstrates that the organisation understands and manages its technology environment responsibly.

How Often Should a Software Audit Be Conducted?

There is no universal answer, but ISACA and ISO/IEC 19770 both support the position that software asset management should be an ongoing discipline rather than a one-time event. For most businesses, an annual audit provides a practical baseline, supplemented by reviews whenever significant changes occur - such as organisational growth, mergers, cloud migrations, or major software deployments.

The first audit is often the most revealing. Many businesses discover discrepancies between what they believed they had and what is actually installed and running across their environment.

What Happens After the Audit?

A software audit is only valuable if its findings are acted upon. The output should include a clear inventory, a summary of compliance gaps and security risks, recommendations for license optimisation, and a prioritised remediation plan.

Working with an experienced IT consultancy ensures that the audit findings translate into practical next steps - not just a report that sits in a folder.

Getting Started

If your business has never conducted a formal software audit, or if your last review was more than a year ago, it is worth understanding where you currently stand. The risks associated with non-compliance, security vulnerabilities, and unnecessary spend are real - and avoidable.
