SaaS Subscription Audit: Cut Unused Software and Close Security Gaps (2026)

Ask a small business owner how many software subscriptions they have and the answer is usually a guess. Ten? Twenty? In practice it is closer to double that, because every team, trial, and "just for this project" sign-up adds one.

That sprawl costs money, and it also creates risk. Every forgotten account is a login that can be stolen and a place where company data can leak. A SaaS subscription audit fixes both problems in an afternoon.

1. Find every subscription you are paying for

You cannot manage what you cannot see. Start by gathering evidence from several places, because no single source has the full picture:

• Bank and credit card statements. Search the last 12 months for recurring monthly and annual charges.
• Your identity admin console. In Microsoft 365 or Google Workspace, review the third-party apps people connected with "Sign in with Microsoft" or "Sign in with Google."
• Your team. Ask each lead what they use daily. This catches free tools that hold real data but never show up on a bill.

Put everything into one spreadsheet with columns for app, owner, monthly cost, number of seats, data it holds, and whether MFA is on. This is the same idea as our IT asset inventory, applied to software. It also exposes shadow IT your team adopted without asking.

2. Cut what you do not use

Now compare seats paid for against seats actually used. Most admin dashboards show the last sign-in date for each user.

• Unused seats. Anyone who has not signed in for 60 to 90 days is a candidate to remove.
• Former employees. Their accounts should be gone already. If they are not, your offboarding checklist has a gap.
• Duplicate tools. Two apps that do the same job, such as file sharing or video calls, rarely both deserve a budget line.
• Over-sized plans. Drop to a lower tier if nobody touches the premium features.

Before you cancel, export anything you need to keep, such as invoices, client records, or project files. Then remove the users, cancel the plan, and delete the account if the vendor allows it. Keep a short note of what you removed and why.

3. Secure the subscriptions that stay

The apps that survive the audit are the ones holding your real data, so make them hard to break into:

• Turn on MFA everywhere. Start with email, accounting, and anything that stores customer information. See our guide to multi-factor authentication.
• Use single sign-on where you can. One managed login is easier to protect and to shut off. We explain how in our SSO guide.
• Store passwords in a team password manager. No sticky notes and no shared spreadsheets. Our password manager guide covers the options.
• Review connected apps. Revoke third-party access you do not recognize, a common tactic in OAuth app phishing.
• Set a renewal reminder. Put each annual renewal on the calendar 30 days ahead so nothing auto-renews unnoticed.

The takeaway

A SaaS audit is not a big project. List every subscription, cut what is unused, and secure what remains. Most businesses save money in the first pass and shrink their attack surface at the same time. Repeat it twice a year, and after every departure, and software stops being something that quietly drifts out of control.

Frequently asked questions

What is a SaaS subscription audit?

A SaaS subscription audit is a review of every cloud app your business pays for or signs in to. You list each one, who owns it, who uses it, what data it holds, and what it costs, then cancel or secure whatever does not earn its place.

How often should a small business audit its software subscriptions?

Twice a year is a good rhythm, plus a quick check whenever someone leaves the company. A short review each quarter is even better if you have more than 20 apps.

How do I find software subscriptions nobody told me about?

Check credit card and bank statements for recurring charges, review the apps connected to your Microsoft 365 or Google Workspace accounts, and ask each team lead what they sign in to. Expense reports and browser password managers also reveal forgotten tools.

Are unused software accounts a security risk?

Yes. An abandoned account often keeps a weak or reused password, no multi-factor authentication, and access to company data. Attackers target exactly these forgotten logins.

What should I do with an app I no longer need?

Export the data you must keep, remove all users, cancel the subscription, then delete the account if the vendor allows it. Record the date and the reason so you have proof for insurance or compliance reviews.
