Every AI subscription your company pays for renews on schedule, whether anyone used it or not. Seats are the clearest example: a fixed price per person, per month, per tool. They accumulate quietly, and they almost never get cleaned up.
Where idle seats come from
- Trials that became subscriptions. Someone tested a tool with five seats. Two people use it. The other three renew monthly.
- People who left. Offboarding checklists cover email and laptops. AI tools rarely make the list.
- Tool hoppers. A team switched from one assistant to another. The old seats were never cancelled.
- Just-in-case seats. Bought for a project that ended, kept for a project that never started.
The math is not small
AI seats run $20-60 per month each. Six idle seats at $40 is $2,880 a year - for nothing. In a 100-person company using three or four AI tools, finding 10-20% of seats idle is completely normal. This is usually the fastest 5-15% anyone cuts from an AI bill, because it requires no behavior change at all.
How to find them
Every major AI tool has an admin page with per-seat activity. Look for last-active dates. The manual routine:
- Once a month, list every seat across every AI tool you pay for.
- Flag anything inactive for 30+ days.
- Ask the owner one question: keep it or lose it?
- Reassign before you cancel - someone else may be paying for a personal subscription out of pocket.
Or let the software nag you
The reason idle seats survive is that nobody owns the monthly check. Optimize watches seat activity across all your tools and flags idle ones automatically, with the dollar amount attached. The awkward cleanup conversation becomes a one-click approval.
