Why Most Companies Have No Idea How Many SaaS Tools They Actually Use
What it looks like from the vendor side when a company's own inventory of its SaaS stack is wrong, and nobody there realizes it yet.
I spent years on the vendor side of enterprise software, selling into companies that, in almost every case, underestimated how many SaaS tools they were actually running. Not by a little. Often by a lot.
I remember pitching into an account where the buyer told us, confidently, that they had "maybe fifteen or twenty tools" across the company. We asked, as part of the sales process, whether they'd done a card statement audit recently. They hadn't. When finance eventually pulled corporate card and expense data as part of an unrelated review, they found closer to sixty active SaaS subscriptions, many purchased directly by individual teams with a company card, entirely outside whatever procurement process existed on paper. Some were duplicates of tools finance already thought they owned centrally.
Counting the stack
Tools we think we have
40
From memory, in a meeting
Tools the card statement has
100+
From the actual ledger
The gap is not made of big platforms. It is made of small subscriptions nobody thought worth mentioning.
Why the real number is always higher than the assumed number
This isn't a one-off surprise, it's close to the default state for any company past a certain size:
- SaaS tools can be purchased by any team with a card, without going through IT or procurement
- Free trials convert to paid plans automatically, and the resulting charge doesn't always get flagged as a new tool
- Tools adopted for a specific project often outlive the project, quietly renewing long after anyone remembers why they were bought
- There's no single source of truth unless someone actively builds and maintains one, and that maintenance rarely survives more than a year without a dedicated owner
Ask a finance or IT leader how many SaaS tools the company runs, and the honest answer is almost always "more than I think," because there's no default mechanism that keeps the number visible.
Why this matters beyond tidiness
Every one of those undiscovered tools is also an undiscovered renewal, with its own notice period and its own auto-renewal clause, sitting outside whatever renewal calendar the company thinks it's tracking. A vendor doesn't need to hide anything for this to work in their favor. If the customer doesn't know the tool exists in their own portfolio, it renews by default, every time, with nobody positioned to ask a single question.
What actually fixes this
A one-time audit helps, but it decays the moment it's finished, because new tools get purchased the same way the old ones were. The companies that stay ahead of this build a living inventory tied to actual billing and contract data, not a spreadsheet from last year's audit that nobody updates.
