What is a ghost seat in SaaS?
A ghost seat is a paid software license assigned to a user who no longer actively uses the tool — either because they left the company, changed roles, or simply stopped logging in.
Details
Ghost seats accumulate silently because vendors bill per assigned license, not per active user. A typical SaaS stack has 20–35% of its seats in a ghost state within 18 months of purchase — that spend renews automatically unless someone reviews it.
The three most common causes are incomplete offboarding (the person left but IT never revoked the license), role change (a former sales rep still holds their Salesforce seat), and free-trial creep (someone tried the tool once and never used it again).
Ghost seats are the single largest source of recoverable SaaS spend for companies under 500 employees. They are safe to reclaim because usage evidence is deterministic — either a login exists in the last N days or it does not.
