## TL;DR
New hires cannot be onboarded because every paid seat is taken: the invite or seat assignment fails with a license limit error. The fix has two parts. Right now: find inactive seats and free them, or buy more seats. Going forward: put seat assignment behind a check that warns before the limit, and automate deprovisioning so departed employees stop holding seats.

## The error
```text
Seat assignment failed: license limit reached
"Your plan includes 50 seats; all 50 are assigned."
```

## Steps
1. Confirm the count. Open the admin billing page and compare assigned seats to the plan limit. Expected output: assigned equals the limit, no seats free.
2. Find reclaimable seats. List assigned seats sorted by last activity and flag accounts for people who left or never activated. Expected output: a short list of seats safe to free.
3. Free or buy. Deactivate the departed accounts, or purchase additional seats if the team is genuinely growing. Expected output: at least one free seat, and the next invite succeeds.
4. Retry the onboarding invite. Expected output: the new hire's seat assigns without the limit error.
5. Add a guard. Warn admins at 90 percent of seats and auto-suspend accounts inactive for 90 days. Expected output: the next crunch triggers a warning, not a failed onboarding.

## When to use
- Invites or seat assignments fail with a license limit message
- Onboarding stalls specifically for new hires while existing users are fine
- The team grew quickly and nobody watched seat counts

## When not to use
- The invite fails with an SSO or directory error: identity problem, not licensing
- The user cannot log in after being assigned: authentication problem
- Billing shows the wrong plan: fix the subscription first

## Tool compatibility
Any per-seat SaaS licensing: identity providers with seat counts, SaaS admin consoles, and HRIS-driven provisioning tools. The reclaim-then-guard pattern works regardless of vendor.

## Variant phrasings
### license limit reached onboarding
Free inactive seats or buy more before retrying.
### cannot assign seat plan full
Same fix: reclaim, purchase, then guard.
### seat assignment failed new hire
Check seat counts before debugging identity.
### out of licenses saas invite
An admin billing problem wearing an onboarding costume.

## Why it happens
Seats are invisible until they run out. Offboarding rarely deprovisions the SaaS seat: the person leaves, the account lingers, and the seat stays assigned forever. Meanwhile onboarding assumes a free seat exists. The two processes are owned by different people (IT vs HR), so the leak compounds silently until a new hire's first day collides with a full plan. It is a process gap, not a software bug, which is why the durable fix is automation on both ends.

## Edge cases
- Guest or external seats count differently: check whether guests consume paid seats in your plan before freeing the wrong accounts.
- Deactivating breaks shared resources: check for docs, dashboards, or API tokens owned by the departing account and transfer ownership first.
- Annual plan with monthly true-ups: buying seats mid-cycle may bill immediately. Confirm with finance, not just IT.
- The count disagrees with the dashboard: pending invites often hold seats. Cancel stale invites to free them.
