Adding seats
A seat is a paid user licence on your Core plan. Admins can add seats themselves from Plan & Billing; reductions apply at renewal.
⚠️ Requires org role Admin.
Seats, members and buyers
- Seats purchased — what you're billed for (the N of M used bar on the plan card).
- Members — people with a Katalyz account in your workspace. Every member with an org role occupies a seat. Removing a member frees their seat for someone else; it doesn't lower the purchased count.
- Buyers — external people you share rooms with. Unlimited and free. See Members vs. buyers.
Core runs from 5 to 30 seats. Above 30, your account manager moves you to Enterprise.
Adding seats yourself
- Go to Settings → Workspace → Plan & Billing.
- On the plan card, click Add seats.
- Enter Seats to add. The dialog shows the per-seat price (Seats are billed at €60 / user / month.), the prorated amount for the months left in your term, the new seat count and the new annual total.
- Confirm.
What happens next depends on your billing:
Situation | Effect |
|---|---|
Subscription not active yet | Seats fold into your pending order, no separate invoice. If you had already signed, you re-sign the updated order. |
Annual (prepaid) term | An immediate prorated invoice for the remaining months; the new seats end with your current term. |
Monthly billing | The seats are added to your next invoice. |
Order without a mid-term expansion clause | The addition needs a signed addendum: review, Review & sign addendum, and the seats plus their invoice apply on signing. |
Every change is recorded in the Seat history log under the plan card — who added how many seats, when, and for how much.
Reducing seats
Seats are committed for the term. To reduce them at renewal, tell your account manager before your notice period starts (shown on your contract). See Cancelling your subscription.
Free licences
Some licence types are granted on top of paid seats and never count toward them (for example admin-viewer licences agreed in your contract). They appear on your order; ask your account manager if you need more.
Unlimited seats
Some contracts have uncapped seats: usage isn't limited, and the plan card reads "N active · M billed (uncapped)". Billing stays based on the purchased seats.
