They register interest
A guest who opens a full event sees a friendly "this event is full" screen and can leave their name and a way to reach them — no spot taken, no headcount touched.
Room control
Event capacity and waitlist, without the scramble.
Set an event capacity limit for the number your venue or budget can hold, and keep a private event waitlist when the room fills. New RSVPs close at your attendance cap; guests can leave their name and contact details so you can invite them when there's room. This venue limit is separate from the guest allowance on your purchased plan.
- A hard headcount cap
- RSVPs auto-close when full
- A real, private waitlist
The cap
A limit that minds the door.
Set the total you can host and a live bar tracks it — 38 of 50 spots filled — counting every yes and every plus-one they bring. Hit the number and new RSVPs close on their own, so you never wake up to more guests than chairs. It's separate from your billing plan: this is the real-world ceiling your room, your budget or your caterer set.
- One number, counted for you
- A live "spots filled" bar
- Plus-ones count toward the total
- RSVPs close automatically at the limit
Nobody left at a dead end
A waitlist for the next opening.
When the room fills, the story doesn't stop — it moves to the waitlist.
You watch demand build
Every sign-up lands under "Interested · event full," newest first, and pings you in the app and by email — so you know exactly how much room you wish you had.
Room for another guest
Make room, then reach out to the waitlisted guests you'd like to invite. If a plan upgrade opens seats, InviteBird emails them automatically; they still need to RSVP to take a spot.
Confirmed guests stay put
Nobody who already said yes is ever bumped, and they can still change their reply. The limit can't drop below the people already in, and if a manual add ever takes you over it, only new RSVPs stay closed.
An overbooked party is a scramble. A full one with a waitlist is a room that runs itself — and a list of people who'd still love to come.
Never pushed over the line
Full means full.
The cap holds even under pressure. If two guests are replying as the last seat goes, the party in progress is trimmed to whatever room is left — never below one — so you're never nudged past your number. And a guest trying to switch back to yes after you've filled up meets the same full screen, so a late change can't overbook you either.
- Late replies trimmed to the room that's left
- Switch-backs re-checked against the cap
- Reopen anytime — raise the limit or switch the cap off
Mind the door
A full room, never an overbooked one.
Cap the headcount, close RSVPs when you're full, and keep a real waitlist ready for the spots that open.

Common questions
Good to know.
Is the capacity cap the same as my plan's guest limit?
No. Your plan's guest limit is about billing; the capacity cap is a real-world attendance ceiling you choose — your venue, your budget, your call. They work independently.
What do guests see once the event is full?
Instead of the Yes / Maybe / No buttons, a new guest sees a "this event is full" screen that invites them to leave their name and an email or phone, so you can reach them if a spot opens. No RSVP is created and no spot is taken.
Is the waitlist automatic?
Collecting it is. Guests add themselves when the event is full and you're notified each time. Letting someone in is your call — make room, then add them from your guest list, so you choose exactly who gets the opening.
Do waitlisted guests get told when a spot opens?
If you upgrade your plan to make room, InviteBird emails your waitlisted guests automatically. If room opens another way, a waitlisted guest who returns to the invitation sees a spot opened and can send their RSVP.
Will confirmed guests ever get bumped when the event fills?
Never. Confirmed guests keep their spot no matter what — only new RSVPs close once you're full. The limit can't be set below your confirmed count, and if you ever end up over it, nobody is removed.
Can I reopen RSVPs after they close?
Yes, instantly. Raise the limit above your current count, or switch the capacity card off, and RSVPs reopen right away.
Put it into practice

- Understand your plan's guest limitSee how attending guests and plus-ones count, and how the billing limit differs from your venue cap.
- See how RSVP changes affect capacityLearn what happens when a guest changes party size or switches back to attending after the event fills.
