Your asset list is probably already wrong
I want to start with a fact that most IT teams already know but hate admitting. Your software asset inventory is almost certainly out of date right now. Not by a little, either. Most companies we talk to at LicenseTrim have asset lists that are missing 15 to 30 percent of the software actually running in their environment. That number gets worse every month you go without a proper review.
The thing is, nobody sets out to have a bad inventory. It starts clean. Someone spends a week documenting every tool, every license, every subscription. It goes into a spreadsheet or maybe an IT asset managment tool. And for about two weeks, it looks great.
Then someone signs up for a new project management tool on their credit card. Another team starts a trial of some analytics platform. An employee leaves and nobody thinks to check what licenses they had. Slowly, the list drifts from reality. Six months later, you're making decisions based on fiction.
What happens when your inventory goes stale
The most obvious problem is money. When you don't know what software you actually have, you can't know what you're paying for but not using. We've seen companies paying for dozens of Zendesk agent seats where the people assigned to those seats haven't logged in for months. That pattern repeats across every SaaS tool in your stack.
But the financial waste isn't even the scariest part. Security is. When you don't have an accurate picture of what software is running in your organization, you have blind spots. Shadow IT, unapproved tools with access to company data, integrations that were set up by someone who left two years ago. These are real attack surfaces that your security team can't protect if they don't know about them.
There's a compliance angle too. If you go through a SOC 2 audit or any kind of regulatory review, one of the first things auditors want to see is an accurate software inventory. Showing up with a spreadsheet that hasn't been touched since last April is not a great look.
Monthly reviews actually work
I know "do a monthly review" sounds tedious. But here's why it works better than quarterly or annual audits. Changes to your software environment happen continuously. People join. People leave. Teams adopt new tools constantly. If you wait three months to catch up, you're dealing with a pile of changes that takes hours to sort through. If you do it monthly, it's a 30-minute task.
We recommend picking a specific day. First Tuesday of the month, whatever works for your team. Pull your latest billing statements from your major SaaS vendors. Cross-reference against your asset list. Look for new subscriptions that appeared and old ones where usage dropped to zero.
The key is making it a habit, not a project. Projects have deadlines and end dates. This doesn't end. Your software environment will keep changing as long as your company exists, and your inventory needs to change with it.
Assign owners or nothing happens
Every tool in your stack should have one person who is responsible for it. Not responsible for using it. Responsible for knowing who uses it, what it costs, and whether the company still needs it. Without that ownership, tools become orphans. Nobody checks on them, nobody questions the renewal, and teh bill keeps getting paid quarter after quarter.
This doesn't mean one person owns everything. Spread it out. The head of sales owns the CRM. The support lead owns the helpdesk tool. Engineering leadership owns the dev tools. When renewal time comes, those owners should be able to answer a simple question: are we getting value from this?
If the owner leaves the company, reassign their tools immediately. This is one of those things that should be on your offboarding checklist right next to revoking access. The tool doesn't stop costing money just because the person who managed it is gone.
Automate the boring parts
Manual tracking will always be part of the picture, but you can take a lot of the pain out of it with some basic automation. Most identity providers can give you a feed of what SaaS apps your employees are signing into. That's a goldmine for catching shadow IT early.
Usage monitoring is the other big one. Instead of asking people "do you still use this tool?" and getting vague answers, just look at the login data. If someone hasn't touched a tool in 60 days, that's a strong signal their license can be reclaimed. That's exactly what we built LicenseTrim to do for Zendesk, and the savings are real.
Some companies try to build all of this in-house with scripts and API calls. That can work if you have the engineering bandwidth, but for most teams it makes more sense to use purpose-built tools. The goal is to spend your time making decisions, not gathering data.
Start small and be honest
If your current inventory is a mess, don't try to fix everything at once. Pick your five most expensive software tools. Get those right first. Know exactly who has licenses, who's actually using them, and what you're paying. Then expand from there.
The companies that do this well share one trait. They're honest about the fact that their inventory will never be perfect. It's a living document, not a finished product. The goal isn't perfection. It's staying close enough to reality that you can make smart decisions about what to keep, what to cut, and what to renegotiate.
That mindset shift, from "we need to build the perfect asset list" to "we need a process that keeps our list useful," is honestly the most important thing I can tell you. Get the process right, and the accuracy follows.
