Shelfware

Software a company has paid for but isn't using — licenses that sit on the metaphorical shelf, billed monthly, generating zero value.

Also known as: unused licenses, dormant seats, wasted seats

Shelfware was originally a 1990s term for boxed enterprise software that companies bought, shelved, and forgot. In the SaaS era it's the same problem in a recurring-revenue wrapper: seats provisioned in a burst (new hire onboarding, a re-org, a big rollout) and never actually used.

The hidden cost isn't only the dollars on the invoice — it's the renewal math. Vendors size next year's contract on this year's committed seats. Every shelfware seat at renewal locks in another year of waste.

Audits typically find 30–40% shelfware ratios in mid-market SaaS stacks. SeatMap flags every shelfware seat in your stack with the exact dollar amount tied to it.
