How much does event registration software cost?

Short answer
There is no single price: vendors charge a subscription, a percentage of ticket sales, a fee per registration, or a mix, and card processing is usually separate. Put your own yearly volume, average ticket price and free registrations through each vendor's written pricing, then add overages, metered email, and the staff time spent on invoices and refunds.
Nobody can answer "how much does event registration software cost?" with one number that fits your year. Shops price the same job four ways, and card fees sit under all of them.
The FAQ answers the decision questions. The sheet below is the arithmetic—use your volumes; the worked numbers are shape only.
Frequently asked questions
There is no single price. Most shops use a subscription, a percentage of ticket sales, a per-registration fee, or a mix — plus separate card fees. Put your own yearly volumes through each vendor's written pricing, then add overages, metered email, and staff time on invoices and refunds.
It depends on yearly ticket revenue. Divide the annual subscription by the percentage fee for a crossover: below it the percentage often costs less, above it the subscription often does. Use real rates, and include free regs if they bill per head.
Percentage-of-sales usually charges nothing on a free ticket. Per-registration often charges for free people too. Always run free events through the quote — a large free night can cost more than a paid conference under a per-head fee.
Usually not. Cards clear through a payment provider. Ask if the platform takes another cut, and whether you connect your own merchant account.
Overages for attendees, events or admins; metered email or SMS; staff time on invoices and refunds when checkout only works for consumers; paper lists when check-in dies without Wi-Fi; rebuilding money history when exports leave out orders or refunds.
What would last year's events have cost in total under your pricing — free regs and overages included? Is payment processing included, and whose rates? On a refund, which fees reverse? What do we pay with zero paid events for three months? Where is the overage schedule?
Not by itself. Card fees and ops time still sit on the year. Treat 0% as one line on the sheet, then run the same arithmetic as any other model. The dedicated 0% guide explains what the phrase does and does not cover.
More detail
Four ways shops charge (often mixed)
| Model | You pay when… | Often suits… | Catch |
|---|---|---|---|
| Subscription | Every month or year, even with no ticket sales | A steady calendar, lots of free or cheap events | Quiet years still bill; watch overages |
| Percentage of ticket sales | Each paid order | A few events, volume unclear | High ticket prices hurt; free tickets may cost $0 here |
| Per registration | Each person who registers (sometimes free ones too) | Headcount you can predict | A big free night can cost more than a paid conference |
| Hybrid | A base fee plus a smaller % or per-head charge | Vendors covering both sides | You have to model both lines — the homepage rarely does |
Card fees are not the platform fee. Stripe, PayPal, or the bank still take their cut. Ask whether the platform takes another cut on top, and whether you connect your own merchant account. For scale, Stripe's published standard rates (checked October 2026): in the UK, 1.5% + 20p for standard UK cards, 2.5% + 20p for EEA cards and 3.15% + 20p for international cards (Stripe UK pricing); in Singapore, 3.4% + S$0.50 for domestic cards, plus 0.5% for international cards (Stripe Singapore pricing). Both add 2% when a currency has to be converted. Use the schedule for the country your account is in.
Price last year on one sheet
For each event note paid registrations and gross ticket revenue, free registrations, refunds, and whether companies needed invoices. Run that sheet against each vendor's written pricing. Ignore "starting at."
# platform_year ≈ subscription
+ (% × paid_ticket_revenue)
+ (per_reg × registrations_that_bill)
processor_year ≈ processor_% × card_volume
+ per_charge × charge_count
# total_year ≈ platform_year + processor_year
Illustrative year only — $400,000 paid ticket revenue, 2,000 paid registrations, 1,500 free. Your figures will differ.
| Illustrative model | Rough platform bill | Note |
|---|---|---|
| $6,000/year subscription + 0% of sales | $6,000 | Free regs add nothing; a quiet year still costs $6,000 |
| 2.5% of paid ticket revenue | $10,000 | Free regs free on platform fee; bill grows with price × volume |
| $3 per registration (paid + free) | $10,500 | 3,500 × $3 — free community nights get expensive |
| $2,400/year + 1% of paid revenue | $6,400 | Hybrid: both lines count |
Add card fees on every column. Quick check when one vendor is mostly subscription and another is mostly a cut of sales: crossover_revenue ≈ annual_subscription ÷ percentage_fee (example: 6000 ÷ 0.025 = 240000). Below that yearly ticket revenue the percentage often costs less; above it the subscription often does. Same sheet to every shortlist—ours included.
