If you want event software with unlimited events and attendees included, the first thing to understand is that "unlimited" is doing a lot of heavy lifting in a lot of marketing copy, and not every platform means the same thing by it. Some platforms genuinely include unlimited events and unlimited registrations in one predictable price. Others say "unlimited" in the headline, then meter you per ticket, per registrant, or per user in the fine print, so your bill quietly climbs every time your event does well. This guide explains what unlimited actually means, which pricing models deliver it and which only pretend to, and how to check before you sign.
Here is the short version for the skim-readers: truly unlimited means the number of events you run and the number of people who attend them have zero effect on what you pay. If a platform's cost goes up when you add an event or sell another ticket, it is not unlimited. It is a taxi meter with a nicer font.
What "unlimited events and attendees included" is supposed to mean
The phrase should mean exactly what it says on the tin: you can run one event or forty, invite fifty people or five thousand, and the price on your invoice does not budge. No per-ticket clip. No per-registrant surcharge. No "you have exceeded your plan's attendee cap, please upgrade" email arriving the morning after your best-selling launch.
This matters because event volume is precisely the thing that grows when you are doing your job well. The cruel irony of most pricing models is that they charge you more at the exact moment you have most earned the right to celebrate. Your event sells out, and your reward is a bigger bill. Truly unlimited pricing breaks that link. Your success stops being a billing event.
If your platform charges more every time your event succeeds, you are not paying for software. You are paying a commission on your own hard work.
The four pricing models hiding behind the word "unlimited"
Almost every event platform uses one of four models. Only two of them can honestly claim unlimited events and attendees. Here is how they actually behave when your numbers grow, with current published or widely reported rates so you can do the maths yourself.
| Pricing model | Example platform | What happens as you grow | Truly unlimited? |
|---|---|---|---|
| Per ticket | Eventbrite (US 3.7% plus 1.79 dollars service fee per ticket, plus 2.9% processing) | Every extra ticket adds cost, forever | No |
| Per registrant | Cvent (reported 7 to 12 dollars per registrant per event, rising from July 2026) | Cost scales with headcount at every event | No |
| Per user (seat) | Bizzabo (reported around 499 dollars per user per month, roughly 17,999 dollars a year floor) | Events and attendees free, but your own team costs more | Partly |
| Flat subscription | Swoogo (from 11,800 dollars a year), eventcloud (125 dollars per user per month) | Run more, sell more, pay the same | Yes |
Read that table one more time and notice the pattern. The models that meter your attendees are the ones that cannot honestly say "unlimited attendees included", because attendees are the meter. The models that meter your events cannot say "unlimited events included", because events are the meter. Only a flat subscription, where usage is not the billing unit, gets to use the word without an asterisk.
Why per-ticket and per-registrant "unlimited" is a magic trick
Per-ticket platforms love the word unlimited because, technically, they will happily let you create unlimited events and sell unlimited tickets. They just take a slice of each one. On a 25 dollar ticket, Eventbrite's US fees work out to roughly 3.52 dollars all in, an effective rate above 14%. Sell 2,000 of those across a year and you have handed over about 7,000 dollars in fees, none of which bought you a single extra feature. You could run a hundred events on the platform and never hit a cap, which is true, but "no cap" is not the same as "no cost per attendee".
Per-registrant enterprise platforms play a similar game one tier up. Cvent, whose Attendee Hub and Event App are reported at 7 to 12 dollars per registrant per event with an increase scheduled from July 2026, will let you run all the events you like. But an organiser running ten events a year at 500 attendees each is looking at roughly 35,000 dollars in per-registrant charges on top of the base licence, before a single other module is added. Unlimited events? Sure. Unlimited attendees at no extra cost? Absolutely not.

The per-user model: closer, but read the seat count
Per-user (or per-seat) platforms are a genuine step closer to unlimited, because your events and your attendees usually are included. What you pay for instead is the number of people on your team who log in to build and run events. Bizzabo, reported at around 499 dollars per user per month with a floor near 17,999 dollars a year, is a fair example: attendees do not move the needle, but adding colleagues does.
This is a defensible model if your team is small and stable. The catch is that events are collaborative. The moment marketing, operations, finance and a couple of on-site staff all need access, "per user" starts to feel a lot like the meter you were trying to escape, just measured in badges rather than tickets. So when a platform says unlimited, always ask the follow-up question: unlimited what, exactly, and what is still metered?
What genuinely unlimited pricing looks like
Flat-subscription platforms are the only ones that can put "unlimited events and attendees included" in the headline and survive their own lawyer reading it. Swoogo, from 11,800 dollars a year, includes unlimited events and registrations in the base fee, which is why mid-market organisers running lots of events tend to like it. eventcloud takes the same flat-fee principle at 125 dollars per user per month, with unlimited events and unlimited tickets as standard and payments running through your own Stripe account, so there is no per-ticket clip on top.
The point is not that flat-fee is always cheapest. For a single small free event, a per-ticket platform where free tickets cost nothing is hard to beat, and we will happily say so. The point is that flat-fee is the only model where the words "unlimited events and attendees included" are literally true rather than a headline you have to caveat. If predictable cost and freedom to run as many events as you like is the goal, that is the model to shortlist.
Five questions to pressure-test any "unlimited" claim
Before you believe the badge on the pricing page, ask these. Any honest sales rep can answer all five in under a minute, and the answers tell you whether "unlimited" is real or decorative.
Does my cost change if I add another event this year? If yes, events are metered.
Does my cost change if twice as many people register? If yes, attendees are metered.
Is there an attendee cap per plan tier, and what happens when I cross it?
Are per-ticket or per-registrant fees passed to the buyer, so they never show on my dashboard but still shape my pricing?
What is the all-in annual number if my busiest realistic year comes true, not my quietest?
That last question is the one that catches people out. Vendors quote you the quiet year. Your future self lives in the busy one. Run the maths on the year you are actually hoping for, then compare a flat subscription against a per-attendee model at that volume. If you would like to see how a flat, unlimited plan compares against a per-registrant enterprise tool for a growing calendar, our eventcloud vs Cvent comparison lays the models side by side, and the numbers behind all of this live on our pricing page.
