Typical pricing models for event software, compared

Event software is sold on at least four different pricing models, and vendors rarely tell you which one you are looking at. The same event can cost wildly different amounts depending on the model, and the cheapest headline is often the priciest total. Here are the models you will meet, what each one does to your budget, and how to read a quote before you sign it.
Before you read a single quote, write down two numbers: your expected turnout and your average ticket price. Those decide which pricing model wins, and a vendor cannot spin them. Walk into every pricing conversation holding your own figures, and the comparison stops being a sales pitch and starts being arithmetic you control.
Per-ticket or per-registration
You pay a fee for every person who registers, as a flat amount or a percentage of the ticket price. This looks cheap for a small event and turns expensive fast at scale. Sell 2,000 tickets and a small per-ticket fee becomes a large line. Watch for free events charged the same way, where the fee has no ticket price to hide behind.
Flat platform fee
You pay one price for the event or a subscription period, regardless of how many register. This rewards a well-attended event: the cost per guest falls as turnout rises. It is easier to budget because you know the number before you sell a ticket. The question to ask is what the flat fee actually includes, and what sits outside it.
Freemium
A free tier with caps, and paid tiers that lift them. Free works for a small internal event. It usually limits guest count, brands the page with the vendor's name, slows payouts, or thins out support. Read the cap and the limits carefully, because the free plan often ends exactly where a real event begins.
The add-ons that sit on top of every model
- Payment processing, a separate percentage on paid tickets
- Badges and on-site printing, often per badge plus hardware
- A branded mobile app and a custom event website
- Check-in hardware and the staff to run it
How to compare two quotes honestly
Put both quotes on the same four lines: platform or per-ticket fee, payment processing, add-ons, and support. Run them against your real expected turnout, not a round number. A per-ticket model can beat a flat fee for a 100-person event and lose badly for a 2,000-person one. The right model depends on your size, not on which deck looked best.
Match the model to your event
There is no single best model, only the best fit for the event in front of you. A small paid conference with 150 tickets can do well on a per-ticket fee, since the total stays low. A large free member event is punished by per-ticket pricing and suits a flat fee, where 5,000 attendees cost the same as 500. Size and ticket price decide the winner, so run your own real numbers before you trust a headline.
Watch the breakpoint. Per-ticket pricing that beats a flat fee at 200 guests can lose badly at 2,000, because the fee scales with you while the flat fee does not. Find the turnout where the two cross, then check which side of it your event sits on. That one calculation tells you more than any vendor comparison page, and it takes about five minutes with a spreadsheet.
We price diggri as a flat quote per event, covering registration, the guest record, check-in, and the live dashboard, with add-ons and payment processing stated plainly before you commit. Whatever vendor you choose, make them show all the lines. The honest price is the one you can see in full before you sign.
