Nonprofit Event Registration Software Comparison

Nonprofit events have a double job: register attendees and raise money. The best nonprofit event registration software handles both without forcing you to bolt a ticketing tool onto a donation tool and reconcile the two by hand. But “best” depends on whether your event is a gala that lives or dies on auctions and sponsorships, a paid conference with detailed registration, or a community program with recurring sign-ups and giving.

This guide compares the platforms nonprofits reach for most: Regpack alongside Givebutter, Zeffy, Classy (now GoFundMe Pro), Bloomerang, Eventbrite, RSVPify, OneCause, and Donorbox, on the things that decide whether your event runs smoothly: registration depth, payment plans and recurring giving, platform and processing fees, and what each tool is genuinely built to do.

A note on sourcing: pricing, ratings, and platform capabilities change constantly. Every figure below reflects each vendor’s own published pricing page as of mid-2026, wherever we could confirm it directly. Where a vendor doesn’t publish a fixed number (e.g., custom quotes or tiered CRM plans), we say so rather than guessing. Always confirm current numbers on the vendor’s own site before you commit.

What Actually Matters in Nonprofit Event Registration

Almost every tool here can take a ticket and a donation. The differences show up in how deep the registration goes and how the money is structured. Score every platform on six things:

Registration depth vs. donation-first design. Many nonprofit tools are donation platforms that have added ticketing, so registration is flat custom fields rather than conditional, branching forms. If your event needs real registration logic, this matters a lot.

Payment plans, deposits, and recurring billing. Can attendees pay over time, and can you run recurring giving or memberships on a schedule?

Fee structure. Platform fee on funds raised, per-ticket fee, payment processing rate, and whether tips or optional fees offset cost. These stack, so compare the total, not just the headline number.

Fundraising tooling. If your event is a gala, auctions, sponsorships, table management, and mobile bidding may matter more than the registration form itself.

Donor data and follow-up. Does a registration become a donor record with history, or just a ticket?

Pricing transparency. Some vendors publish real numbers; others quote on request.

The biggest fork is donation-first versus registration-first. Donation platforms are excellent at fundraising pages and recurring giving, but usually treat event registration as ticket types plus custom fields. Registration platforms handle the conditional forms, payment plans, and approvals, but you should confirm how each handles donations and tax receipts.

The Platforms At A Glance

Fee structure, registration depth, and what the tool is built for are the three things to hold side by side.

1. Regpack

Pricing model: tiered annual plans by organization size, with unlimited forms, admins, and reports. No per-registration fee.

Payment processing: Regpack states rates starting at 1.5% per transaction, depending on volume, card mix, and plan tier (Regpack’s published rate; get a custom breakdown on a demo call).

Payment plans, deposits, recurring billing: all native. Conditional forms: yes, forms branch on earlier answers.

Best for: nonprofit programs and events that need real registration logic, payment plans, approvals, and recurring billing on one platform. Regpack states it is trusted by more than 6,000 organizations worldwide and is PCI-DSS Level 2 certified, SOC 2 Type II audited, and GDPR compliant.

2. Givebutter

Pricing model: 0% platform fee when donor tips are enabled (Givebutter covers processing in that case too, per its “Givebutter Guarantee”). If tips are disabled, a flat 3% platform fee applies, plus standard processing (2.9% + $0.30 for cards, 1.9% + $0.30 for ACH). An optional Givebutter Plus tier adds CRM features, priced by contact count.

Conditional forms: yes, forms branch on earlier answers. Payment plans / recurring: pledge installments and recurring donations are supported; confirm the current depth of conditional registration logic directly with Givebutter for complex events.

Best for: nonprofits seeking a genuinely free, all-in-one solution for donations, fundraising pages, and event ticketing.

3. Zeffy

Pricing model: 100% free for nonprofits. No platform or processing fees are charged to the organization. Zeffy funds itself entirely through optional donor tips at checkout, which donors can adjust or remove, and covers processing costs itself rather than passing them through.

Conditional forms: limited. Zeffy’s forms are functional but not built for complex branching logic. Payment plans/recurring: recurring donations and memberships are supported; deposits, installment plans, and approval workflows for complex event registration are not where Zeffy is strongest.

G2: 4.9/5 from roughly 930 reviews. Capterra: 4.8/5 from roughly 480 reviews.

Best for: small to mid-size nonprofits, PTAs, and volunteer-run organizations that want a genuinely zero-cost way to handle donations, simple event ticketing, and memberships, and don’t need conditional registration logic or payment plans.

4. Classy (GoFundMe Pro)

Pricing model: custom, contact-sales pricing with annual contracts. Third-party trackers list plans starting in the low hundreds per month, but confirm current tiers directly with Classy since public listings vary.

Payment plans / recurring: strong recurring giving tools; confirm current payment plan and conditional form depth directly with Classy.

Best for: mid-to-large nonprofits wanting an enterprise fundraising platform with polished donation pages and peer-to-peer campaigns.

5. Bloomerang

Pricing model: subscription-based CRM plans, with event management features included in the Standard and Premium tiers rather than sold separately. Bloomerang does not publish a flat event-ticketing price; check its pricing page for current rates based on record count.

Payment plans / recurring: strong recurring giving through the CRM; event-specific payment plans and conditional forms are lighter than dedicated registration platforms. Bloomerang itself describes its product as a donor CRM first, not standalone event-management software.

Best for: nonprofits that want a donor CRM first, with event ticketing feeding directly into donor records, rather than a dedicated event-registration tool.

6. Eventbrite

Pricing model: free for free events. Paid tickets carry a 3.7% + $1.79 service fee per ticket, plus 2.9% payment processing per order (US pricing; other countries use a different combined rate).

Payment plans/deposits: not a native feature. Donations are handled as a donation-style ticket type rather than integrated fundraising.

Best for: public and ticketed nonprofit events that benefit from Eventbrite’s discovery marketplace, keeping in mind that it is a ticketing platform, not a donor CRM.

7. RSVPify

Pricing model: per-ticket fees plus standard payment processing; RSVPify also lists nonprofit-specific rates on request. Confirm current numbers directly on RSVPify’s pricing page, since published rates shift.

Payment plans/deposits: deposits are supported natively; installment plans typically run through Stripe. Conditional/branching forms: yes.

Best for: invitation-driven nonprofit events (galas, donor dinners) that need RSVPs, seating charts, and conditional forms.

8. OneCause

Pricing model: tiered plans, from pay-as-you-go to an annual Professional Auction & Event plan. OneCause does not publish a single flat processing rate; request current pricing directly.

Payment plans, deposits, recurring billing: native. Conditional forms: yes, forms branch on earlier answers.

Best for: fundraising events (galas, auctions, golf outings) where mobile bidding and table management matter as much as the registration form.

9. Donorbox

Pricing model: tiered platform fee (Donorbox publishes different rates for its standard and premium event/fundraising features) plus standard payment processing, with a reduced processing rate for verified nonprofits. Confirm current tiers directly with Donorbox, since published rates vary by source.

Payment plans/deposits: recurring donations are a strength; native payment plans and conditional forms for complex event registration are not; ticketing here is closer to donation-ticket types than branching forms.

Best for: nonprofits seeking simple, low-cost ticketed or free events integrated with donation tooling.

Choose Them, Choose Regpack: An Honest Answer

These tools are built for different jobs. Match the tool to the event.

Choose OneCause if your event is a gala or auction, and if mobile bidding, table management, and live fundraising are at its heart.

Choose Givebutter or Zeffy if you want a free or near-free, donation-first tool with simple event ticketing and don’t need conditional registration logic.

Choose Classy (GoFundMe Pro) or Bloomerang if your priority is an enterprise fundraising platform or donor CRM, with events as a secondary priority.

Choose Eventbrite if you need public discovery for a ticketed event and don’t need a donor CRM.

Choose RSVPify if your event is invitation-driven and needs RSVPs, seating, and conditional forms.

Choose Regpack when the registration itself is the hard part: when forms need to branch, when attendees pay deposits and installments that should collect automatically, when you run recurring billing or memberships, and when you need approvals, waitlists, and live rosters with balances, all on one platform with a predictable annual cost.

Regpack processing starts at 1.5%. Many nonprofit tools are donation platforms that have added ticketing; Regpack is a registration platform, which is the difference when your event is more than a ticket. Regpack states it is used by more than 6,000 organizations.

When Regpack Is The Best Fit

Regpack is the strongest pick on this list when:

• Your registration has real logic: prices, questions, and follow-ups that depend on who is registering and what they answered.
• Attendees or members pay over time, and you want deposits, installments, and recurring billing to collect automatically.
• You run programs, memberships, or multi-event registration, not just one-off ticketed galas.
• You want a predictable annual cost, with processing starting at 1.5%, rather than a platform fee that scales with funds raised.
• Your bookkeeper expects revenue to be entered in QuickBooks without retyping, or your team wants a REST API and webhooks.

If your event is primarily a fundraising gala built around auctions and mobile bidding, a dedicated fundraising tool like OneCause may be a better fit for you, and we will say so. If your need is event registration with conditional forms, payment plans, and recurring billing, Regpack is the strongest fit on this list.

Frequently Asked Questions

What is the best nonprofit event registration software in 2026?

It depends on the event. For galas and auctions, OneCause is built specifically for that use case. For free or low-cost donation-first events, Givebutter and Zeffy are strong, genuinely no-cost options. For enterprise fundraising and donor CRM, Classy (GoFundMe Pro) and Bloomerang lead. For events that need real registration logic, conditional forms, payment plans, recurring billing, and approvals, Regpack is the strongest fit. Match the tool to whether your event is fundraising-first or registration-first.

How much does nonprofit event software cost?

Fee models differ widely. Some charge a platform fee on funds raised or per ticket (Eventbrite’s 3.7% + $1.79 + 2.9%, for example). Some are genuinely free to the nonprofit and funded by optional donor tips (Zeffy covers both platform and processing costs this way; Givebutter waives its platform fee this way but only fully waives processing under its Guarantee terms). Others quote custom annual pricing (Classy, Bloomerang, OneCause). Regpack uses tiered annual plans with no per-registration fee and processing starting at 1.5%. Compare total cost against your real attendance and fundraising volume, not just the headline rate.

What is the difference between donation software and registration software for events?

Donation-first platforms (Givebutter, Zeffy, Donorbox, Classy, Bloomerang) excel at fundraising pages and recurring giving but usually handle event registration as ticket types plus flat custom fields. Registration-first platforms like Regpack handle conditional, branching forms, payment plans, deposits, approvals, and live rosters, the depth you need when an event is more than a ticket. If you need both, confirm how each tool handles the side it wasn’t built for.

Is Regpack secure and compliant?

Regpack states it is PCI DSS Level 2 certified, SOC 2 Type II audited, and GDPR compliant, which matters when you collect donor and registrant data and process payments. For any other vendor, confirm their current certifications on their own site.

The Honest Summary

If your event is a fundraising gala built around auctions, the dedicated fundraising tool above may be a perfect fit.
