Event Registration Software for Nonprofits: What It Really Costs

In summary

• The licence fee is not the decision. Payment processing plus platform percentage is taken off every ticket and every donation, so a “free” registration tool with a higher take rate can cost a charity more than a paid one over a single 300-delegate conference.
• Four vendors dominate the nonprofit SERP — Givebutter, Classy, Bloomerang Events and Eventbrite for Nonprofits — and they use four different commercial models: tip-supported, subscription-plus-percentage, CRM module, and per-ticket fee. We describe each model and do not quote their numbers, because we only publish prices we have read off a vendor pricing page ourselves.
• Unbounce, verified 18 August 2026: Starter $29/mo ($22 annual, 5 pages, 500 visitors, 1 user); Build $99/mo ($74, unlimited pages, 20k visitors, AI copy); Experiment $149/mo ($112, unlimited A/B, 30k visitors, 3 users, 2 domains); Optimize $249/mo ($187, Smart Traffic, 50k visitors, 5 users, 3 domains). 25% off annual.
• Combined donation-plus-registration flow — “add a gift to your ticket” at checkout — is the single feature most worth having, and it is the one generalist ticketing tools handle worst. Test it as a delegate before you sign anything.
• Free tiers are real but they cap the things a research charity needs: custom fields, branded receipts, gift-aid or tax-receipt handling, and the number of events or attendees per period. Read the cap, not the headline.
• Do not buy Unbounce if you have no ticketing platform at all and expected one product to do everything — it is the page layer, not the backend, and buying it alone leaves you without checkout.

Four commercial models, and where the money actually goes

Unbounce pricing verified from the vendor pricing page, 18 August 2026. No competitor prices are quoted anywhere on this page — we only publish figures we have read off a vendor page ourselves. Payment processing is charged by the card processor in every model, including the free ones.

Dimension	Donation-first platforms	Generalist ticketing	Registration page layer (Unbounce)
How they charge	Either a voluntary tip added at checkout, or a subscription plus a percentage of funds raised. Nonprofit-specific tiers are standard.	A per-ticket fee, usually a percentage plus a flat amount, deducted before payout. Nonprofit programmes exist but are applied for, not automatic.	Flat monthly licence. Starter $29/mo ($22 annual) up to Optimize $249/mo ($187 annual). Nothing scales with funds raised.
Free tier	Common, and genuinely usable — but usually funded by the checkout tip, which is money your delegate could have given you.	Free only for genuinely free events. The moment you sell a ticket, fees apply.	No free tier; 25% off annual billing is the discount that exists. We will not invent one that does not.
Donation at checkout	Native and well designed — the reason the category exists. Ask a gift on the ticket page, again at checkout, and on the receipt.	Usually a bolt-on: an extra “add a donation” line item with no donor record behind it.	Not applicable — the gift is captured by your ticketing backend. Unbounce frames the ask before checkout.
Donor record	Yes. Registration and giving history sit against one constituent.	No. You get an attendee list and a CSV, and your CRM import becomes a job.	No. Leads pass through to your CRM or ticketing tool.
Page control and testing	Templated. Branding, a hero image, some colours. Little to no A/B testing.	Templated and often heavily co-branded with the marketplace.	Full control of layout and copy; unlimited A/B testing from Experiment $149/mo ($112 annual); Smart Traffic on Optimize $249/mo ($187 annual).
Cost behaviour as the event grows	Rises with income. A successful gala costs more to run than a quiet one.	Rises with tickets sold, linearly and visibly.	Flat until you exceed the visitor allowance on your tier. A sold-out event costs the same as an empty one.

The practical consequence: page-layer cost is fixed and backend cost is variable. That is why the break-even calculation below matters more than any feature comparison.

Your real cost is a stack, and the licence is the smallest layer

Every quote you are about to receive hides the same three-layer stack. Layer one is payment processing, charged by the card processor on every transaction in every model including the free ones — nobody moves money for nothing. Layer two is the platform take: a percentage of funds raised, a per-ticket fee, or a voluntary tip added to your delegate’s basket. Layer three is the licence, the number procurement spends nearly all its time on.

For a research charity running a 300-delegate symposium with a donation ask attached, layers one and two will almost always dwarf layer three. A vendor that charges nothing up front and takes a percentage of everything is not cheaper — it has moved the cost onto the part of your budget you do not scrutinise, because it never arrives as an invoice. It arrives as a smaller payout.

This is why we lead with a flat-fee product. Unbounce sits at layer three only: no take rate, no per-ticket fee, no tip prompt. Verified 18 August 2026, Starter is $29/mo ($22 billed annually) with 5 pages, 500 visitors and 1 user, and the annual discount across the range is 25%. If your charity runs three or four events a year, five pages is five events. That is not an argument for buying Unbounce instead of ticketing software — you still need a checkout — but for keeping the layers separate so you can see what each costs.

One honest caveat: separating the layers means two systems and a hand-off between them. If your team is one part-time events officer, the integrated platforms below will be less work, and less work has a cash value too.

Which vendors run genuine charity tiers — and what the free plans actually cap

You are about to google four names, so let us handle them directly. Givebutter, Classy, Bloomerang Events and Eventbrite for Nonprofits dominate this search, and each has a materially different commercial shape. We will not print their prices — we only publish figures we have read off a vendor pricing page ourselves, and these change by region, by programme and by whether you are approved for a nonprofit rate. Check the number on the day you buy; the shape of each model matters more anyway.

• Tip-supported donation platforms. No licence, or a very small one; the platform asks your delegate to add a voluntary tip at checkout. Genuinely free to your organisation — but the tip competes with your own donation ask for the same delegate’s goodwill in the same basket, which is a real cost you will not see on any invoice.
• Subscription plus a percentage of funds raised. A licence with nonprofit tiering, plus a cut of what you raise. Strong donor records and campaign tooling; the percentage is the term to negotiate, and it is negotiable at volume more often than vendors advertise.
• Events as a module of a nonprofit CRM. Registration bolted onto the constituent database you may already run, so a delegate and a donor are the same record. If you already licence the CRM, this is usually the cheapest option available.
• Generalist ticketing with a nonprofit programme. Marketplace reach and mature ticketing, with a discount or fee waiver you apply for rather than receive automatically. Best when you need people who do not know you yet to find the event.

Now the caps, because “free event registration for charities” is real in a narrower way than it sounds. Free tiers typically restrict some combination of: events or attendees per period; custom registration fields, which breaks first for academic events needing dietary requirements, accessibility needs, abstract titles and institutional affiliation; branded and tax-compliant receipts, including gift aid declarations; multi-track agendas; and user seats. Read those against your actual event rather than a generic one, then register for your own event on each shortlist platform as a delegate, with a card, and refund yourself. Twenty minutes of that beats three demos.

Combined donation-plus-registration: how the checkout should behave

For a research charity the point of an event is rarely ticket income; it is the room, the relationships and the giving that follows. So the flow that matters is the one where a delegate buying a symposium ticket adds a gift on the same screen, with one card entry, and receives one receipt that separates the two — because a ticket is a purchase and a gift is a donation, and your finance team and your tax treatment care about that distinction even when your delegate does not.

A well-built combined flow does four things. It asks at the right moment — after the ticket is chosen and before payment, not on a separate page afterwards where most people never arrive. It anchors suggested amounts to the ticket price rather than showing an empty box. It splits the transaction in the back office, so the gift lands as a donation with the right fund code and receipt type rather than as event income. And it attributes both to one constituent record, so next year’s invitation knows this person gave.

Donation-first platforms do this properly; it is the reason the category exists and the honest reason a charity might accept their percentage. Generalist ticketing tools mostly do not: you get an “add a donation” line item with no donor record behind it, and reconciling gifts out of event income becomes a month-end job. If combined giving is central to your event economics, weight this above almost everything else.

The page layer fits before all of it. The decision to give is largely made on the page that sells the event; the checkout only collects it. That is Unbounce’s job — a single-purpose registration page making the case for attending and for giving in your own words, with unlimited A/B testing from Experiment at $149/mo ($112 annual) if you want to test which framing raises more. Our conversion rate optimisation tools guide covers the testing discipline, and clinical trial recruitment landing pages shows the same mechanics applied to research participant sign-up.

When the “free” platform costs more than the paid one

Run this on the back of an envelope with your own numbers — we will not invent percentages for vendors whose pricing page we have not read.

1. Take your realistic event total. Ticket income plus expected donations: the figure you would defend to your trustees, not the optimistic one.
2. Multiply it by each platform’s total take — platform percentage plus per-ticket fee plus processing, as quoted to you on the day. Where the platform is tip-supported, estimate the tip rate conservatively and treat it as a cost, because it is money leaving the same basket.
3. Add the licence. For the page layer that is Unbounce Starter at $29/mo ($22 annual), or Build at $99/mo ($74 annual) if you need unlimited pages and traffic headroom. Verified 18 August 2026.
4. Compare totals, then compare again at double the event size. This is the step people skip. Percentage models are cheap when you are small and expensive when you succeed; flat models are the reverse. The question is not what this costs for the spring symposium, but what it costs if the spring symposium goes well.

The break-even is where the extra percentage a donation-first platform takes exceeds the licence of a lower-take alternative plus the page layer. Below that line, take the free or tip-supported option and spend nothing — genuinely the right answer for a small charity running one annual dinner. Above it you are paying a variable tax on your own fundraising success, and a fixed licence is cheaper and easier to forecast.

The trade-off we will not paper over: the saving from a lower-take backend can be entirely consumed by the staff time of running two systems and by a broken hand-off between page and checkout. A dropped UTM, a mismatched attendee list, a delegate who registers but never pays — these are real failure modes of a split stack, and integrated platforms exist because that hand-off is annoying. Price the annoyance honestly.

What Unbounce is, what it is not, and who should not buy it

Unbounce is a landing page builder. Here it owns the registration page — the URL you put in the email, the funder newsletter and the printed programme — and hands the delegate to your ticketing platform’s checkout. It does not issue tickets, scan anyone in at the door, hold a donor record, manage a multi-track agenda or produce your badge run. Any page telling you otherwise is selling you something.

What it does well here is narrow and useful. Pages are yours rather than a marketplace’s, so a funder clicking through sees your organisation, and you can run a different page per audience — clinicians, patient representatives, sponsors — without waiting for a web team. Verified 18 August 2026: Starter $29/mo ($22 annual, 5 pages, 500 visitors, 1 user); Build $99/mo ($74, unlimited pages, 20,000 visitors, AI copy); Experiment $149/mo ($112, unlimited A/B, 30,000 visitors, 3 users, 2 domains); Optimize $249/mo ($187, Smart Traffic, 50,000 visitors, 5 users, 3 domains), with 25% off annual billing. Watch the traffic allowances rather than the page counts — Starter’s 500 visitors bites first if you are promoting to a large mailing list.

Do not buy Unbounce if you have no ticketing backend and expected one purchase to solve registration end to end; you will have bought a fine page with nowhere to pay. Do not buy it if your events are internal seminars with fifteen attendees — a free form and a calendar invite is the correct tool. And do not buy it if nobody will write or test the page, because the licence only pays back if someone iterates on it.

A one-hour decision path

You are purchase-ready, so do not turn this into a quarter-long procurement.

1. If you already licence a nonprofit CRM, price its events module first. The marginal cost is usually lowest and the donor-record problem is already solved. If it takes a registration and a gift in one basket, stop here.
2. If not, and your event is small and mostly free, take a free or tip-supported platform — after reading the caps on custom fields and receipts against your actual registration form.
3. If the event is ticketed and the donation ask is material, run the break-even above — at your realistic figure and again at double it.
4. Then, separately, decide who owns the registration page. If the honest answer is “the platform’s template, because nobody has time”, accept that and move on. If someone will write and test it, put Unbounce in front — Starter at $29/mo ($22 annual) for a few events a year, Build at $99/mo ($74 annual) once traffic is real.
5. If your problem is complexity rather than cost — abstract submission, multi-track sessions, badge printing, thousands of delegates — this is the wrong page. Read event registration platforms, which compares the field on capability and scale rather than on charity pricing.

Whatever you choose, keep delegate data flowing somewhere durable — lists that live only inside a ticketing platform become unusable the moment you change vendor.

Fixed licence, no cut of your fundraising

Unbounce Starter is $29/mo ($22 billed annually) for 5 pages, 500 visitors and 1 user; Build is $99/mo ($74 annual) with unlimited pages, 20,000 visitors and AI copy; Experiment is $149/mo ($112 annual) with unlimited A/B testing; Optimize is $249/mo ($187 annual) with Smart Traffic. Annual billing is 25% off — verified 18 August 2026. Nothing here scales with the money you raise, which is the whole point at this budget level.

Frequently asked questions

What is the best event registration software for nonprofits?

It depends which cost you are controlling. If you already run a nonprofit CRM, its events module is usually the cheapest credible option and solves the donor-record problem for free. If your event is small and largely free, a tip-supported donation platform costs nothing up front. If tickets and donations are both material, run the break-even in this guide, because the platform percentage decides the total, not the licence. Separately, the registration page is worth owning — Unbounce starts at $29/mo ($22 billed annually), verified 18 August 2026, and takes no cut of what you raise.

Is there genuinely free event registration for charities?

Yes, with caps that matter. Free and tip-supported plans are real, and for a single annual dinner with simple ticketing they are the right answer. They typically restrict events or attendees per period, custom registration fields, branded and tax-compliant receipts including gift aid declarations, multi-track agendas and user seats. Payment processing is still charged by the card processor in every case — free means no platform licence, never no cost.

How do Givebutter, Classy, Bloomerang Events and Eventbrite compare on price?

They use four different commercial models: tip-supported at checkout, subscription plus a percentage of funds raised, an events module inside a nonprofit CRM, and per-ticket fees with a nonprofit programme you apply for. We deliberately do not print their numbers — we only publish prices we have read off a vendor pricing page ourselves, and these vary by region, programme and approval status. Get the figure quoted on the day, then compare total take at your realistic event size and again at double it.

Can delegates add a donation when they register?

On donation-first platforms, yes, and it is the strongest argument for paying their percentage. A good combined flow asks after the ticket is chosen and before payment, suggests amounts anchored to the ticket price, records the gift as a donation with the correct fund code and receipt type rather than as event income, and attributes both to one constituent record. Generalist ticketing tools usually manage only a bolt-on line item with no donor record behind it.

Where does Unbounce fit if it does not sell tickets?

It owns the page in front of the checkout — the URL you put in the email, the funder newsletter and the printed programme — and hands the delegate to your ticketing platform to pay. That page is where the decision to attend and the decision to give are actually made. Starter is $29/mo ($22 billed annually) with 5 pages, 500 visitors and 1 user; Build is $99/mo ($74 annual) with unlimited pages and 20,000 visitors; Experiment is $149/mo ($112 annual) with unlimited A/B testing; Optimize is $249/mo ($187 annual) with Smart Traffic. Annual billing is 25% off, verified 18 August 2026. Buy it alongside a checkout, never instead of one.

Should we buy now, or wait until the event is closer?

Buy the page layer early and the ticketing late. Registration pages earn their money in the promotion window, so a page that goes live eight weeks out and is iterated twice beats a perfect page published a fortnight before. Unbounce Starter at $29/mo, or $22/mo on annual billing at 25% off, is small enough to start before the ticketing decision is settled, and it works with whichever backend you choose — verified 18 August 2026. There is no discount code and no deadline here; we will not invent urgency that does not exist.
