Do you really know what software your company has installed? Here's how you can find out

The company's software inventory is something that few IT managers could accurately recite from memory. Try this: Ask them how many tools the company is currently using—it's rare for the answer to be exact.

Each department purchases its own tools. Every new employee adds to the total number of leave days. Every project brings with it new subscriptions that, months later, no one can remember why they were signed up for. The result is an inventory of software that exists but that no one has actually mapped out.

Why this is a problem (even though it may seem harmless)

Not knowing what software you have installed isn't just a matter of organization. It has very specific consequences:

- Direct cost overrun. You're paying for tool licenses that no one uses anymore, or that renew automatically because the person who purchased them is no longer with the company.

Security risk. Software that is not updated or monitored is one of the most common entry points for vulnerabilities.

Compliance risk. If you don't know what you have, you can't prove that you comply with licenses, contracts, or regulations such as NIS2 or the National Security Framework.

Decisions Made in the Dark. Without real visibility, any technology renewal plan is based on assumptions, not data.

How to Find Out What Software Your Company Has Installed

The good news is that this doesn't require checking each computer individually or relying on each employee to fill out a form. There are three ways to approach this, ranked from least to most reliable:

1. Manual review (quick, but limited)

Ask each department what tools it uses. It's useful for getting an initial overview, but it always falls short: no one remembers everything they've signed up for, and shadow IT (applications signed up for without going through IT) is, by definition, left out.

2. Review of Expenses and Billing

Cross-check recurring charges on corporate credit cards and bank accounts against the known inventory. It's a good way to detect shadow IT, but it's reactive: you discover the spending, not the actual usage.

3. Automated discovery (the reliable option)

IT asset management (ITAM) software continuously scans the network and devices—with or without the need to install an agent—and generates a constantly updated inventory: what is installed, on which device, since when, and at what level of actual usage. This eliminates the most dangerous blind spot: the one that nobody knew existed.

What you should be able to answer at any time

A well-managed software inventory allows you to answer questions such as the following without having to search or ask:

- How many licenses do we have for each tool, and how many are actually being used?

Which software is about to expire or be renewed?

Are there any apps installed that shouldn't be there?

Can we demonstrate, right now, what we have installed if an audit requires us to do so?

If the answer to any of these questions is “I’m not sure,” that’s a clear sign that the current inventory isn’t fulfilling its purpose.

From Visibility to Control

Knowing what software you have is the first step, but the real value lies in what you do with that information: eliminating duplicates, canceling unused subscriptions, planning for renewals, and having the documentation ready before an audit requests it.

An ITAM platform integrated with IT service management doesn't just give you the inventory—it gives you context: who uses each tool, what incidents it has generated, and whether its cost is justified by its actual use.
