What event software actually costs

The honest math on per-registration fees versus flat annual pricing, including where flat pricing does not win.
The Real Cost
Event software costs more than the subscription line implies.
Per-registration fees, module unlocks, and support tiers can quietly double what you actually pay. Here’s the honest math, including where they genuinely don’t apply.
Every event software comparison eventually comes down to a single question someone asks in a budget meeting: what does this actually cost us, all in, by the end of the year.
That question is harder to answer than it should be, because most of the market doesn’t price by the year. It prices by the registration, the module, the support tier, each one a separate line that only shows up once you’re already a customer. None of that is dishonest exactly, it’s just built in a way that makes the sticker price and the real price two different numbers.
We’d rather walk through the actual math, including the part where the more expensive-looking option is sometimes the right one.
The three pricing models in event tech
Broadly, event software gets priced one of three ways.
Per-registration charges you a fee for every attendee who registers, typically somewhere in the €3 to €8 range per person, on top of a base platform fee. It scales with your event automatically, which sounds convenient until your event actually succeeds.
Per-module keeps the core platform cheap or free and charges separately to unlock CRM, matchmaking, marketing tools, or advanced check-in. The quote you get in a first call often reflects only the base tier, with the modules you’ll eventually need priced as upsells later.
Flat annual charges one price for a package, scaled by a size tier rather than by each individual registration, with everything in that package included. This is the model we use at run.events: four packages from €4,300 to €9,900 a year, unlimited events and unlimited seats within your tier.
None of these is a scam. Each makes sense for a different kind of organizer, which is exactly the point of the next two sections.
Where per-ticket pricing genuinely wins
If you’re running one event a year, comfortably under a few hundred attendees, per-registration pricing is often the cheaper, simpler choice, and we’d tell you that even though we don’t sell it that way.
Worked example: the small single event
150 attendees, one event a year, at a typical market rate of around €5 per registration: roughly €750 in ticketing fees for the year. Any flat annual platform, ours included, starts well above that. At this scale, the per-ticket model is doing exactly what it’s supposed to do.
If that’s your organization, a flat annual platform is very likely the wrong purchase, not because the platform is bad, but because you’re paying for capacity you won’t use.
Where the math flips: 800 to 2,000+ attendees a year
The per-registration model scales with your success, which is the part that stops being convenient once you’re actually successful. Every additional attendee, every additional event, every returning sponsor adds another line to the bill, in a way a flat annual price simply doesn’t.
Worked example: the growing portfolio
An organizer running three events a year, 600 attendees each, 1,800 total. At a typical market rate of €5 to €7 per registration, that’s roughly €9,000 to €12,600 a year in ticketing fees alone, before any module unlocks or premium support fees on top. On run.events’ Professional package, that same portfolio runs on a flat €7,100 a year, with CRM, agenda tools, and unlimited additional events already included.
Call it a success tax: the better your event does, the more a per-registration model charges you for it. Somewhere between 800 and 2,000 annual attendees, depending on your exact rate and module needs, the flat annual model stops being the “premium” option and starts being the cheaper one. The crossover point moves depending on your specific numbers, but the direction of the math doesn’t.
The hidden costs checklist
Whichever model you’re comparing, these are the line items that tend to appear after the first quote, not during it.
Ask about these before you sign anything
- Onboarding fees — one-time setup costs, sometimes disclosed upfront, sometimes not. Ours is a published €990.
- Support tiers — faster response times and a dedicated account manager are often a separate monthly fee. Ours run €299 to €899 a month, on top of the platform, and are published on our pricing page.
- Overage fees — what happens if your event outperforms your registration cap mid-event. Ask what the per-head cost is above the line you budgeted for.
- Module unlocks — CRM, matchmaking, and marketing tools that looked included in the demo but turn out to be a separate line item at contract time.
None of these are unreasonable on their own. The problem is when four small ones show up in the same invoice and nobody budgeted for the total.
Building your own TCO comparison
You don’t need a finance degree to build a real total cost of ownership comparison, you need six line items and the discipline to fill in every one of them for every vendor you’re evaluating, not just the ones that make a quote look good.
| Line item | What to ask |
|---|---|
| Base platform fee | Annual or per-event, and what it actually includes |
| Per-registration cost | Rate × your realistic attendee count, for the full year |
| Module fees | CRM, matchmaking, marketing, check-in, priced separately or included |
| Onboarding / setup | One-time fee, and what work it actually covers |
| Support tier | Response time you need, and what it costs to get it |
| Overage buffer | Cost if you exceed your planned attendee count |
Total each vendor for Year 1 and Year 3. The three-year number is where per-registration pricing tends to reveal itself, since the fees compound with every event you run, while a flat annual price stays exactly where it started.

Recap
Event software gets priced three ways: per-registration, per-module, or flat annual. Each fits a different kind of organizer. Per-registration pricing is often the cheaper, simpler choice for a single small event under a few hundred attendees. The math flips somewhere between 800 and 2,000 annual attendees, where per-registration fees compound into a real success tax and flat annual pricing becomes the cheaper option. Before signing anything, ask about onboarding fees, support tiers, overage fees, and module unlocks, the four costs that tend to appear after the first quote.
