Free Event Registration Software for Nonprofits: What's Actually Free

"Free" in event software means at least three different things. If you do not know which type you are signing up for, you may find yourself locked out of features two weeks before your gala — or paying more in per-ticket fees than a paid subscription would have cost.

Three Types of "Free"

Freemium. The platform is genuinely free up to a limit — a cap on attendees per event, number of active events, or team members. No credit card required. You keep using it free as long as you stay within those limits. If your event grows past the cap, you upgrade or you stop at the limit.

Free trial. Full features for 14 to 30 days, then you pay. This is useful for evaluating a platform before committing, but it is not a sustainable free tier. If your event date falls after the trial ends, you will need to decide quickly whether to pay or migrate to something else.

Free to list. No monthly subscription fee, but the platform takes a percentage of every ticket sold plus a flat per-ticket fee. The platform is only free if your event is free. Once you sell tickets, you pay — often more than a flat monthly plan would have cost.

Most platforms use some combination of these models. Read the pricing page for all three before you decide.

What You Give Up on a Free Plan

Freemium tiers are real — but they come with gates. The features that matter most to nonprofits are almost always behind a paid upgrade. Common gates on free plans include:

• Branded confirmation emails. Free plans often send confirmations with the platform's branding, not yours.
• Broadcast messaging to attendees. Sending a reminder or update email to everyone registered is typically a paid feature.
• Seating charts and table management. Needed for galas and dinners — rarely available on free tiers.
• Fundraising and donation add-ons. Silent auctions, donation at checkout, and raffle tools are almost always Pro or paid features.
• Full analytics. Registration source tracking, revenue dashboards, and export reports are gated on most platforms.
• Multiple active events. Many free tiers limit you to one active event at a time.

If you need any of these for your event, account for the cost of upgrading before you build your event on a free tier.

When a Paid Plan Saves Money

If you are running a "free to list" platform and selling tickets, do the math first.

Say your event has 120 paid tickets at $50 each. A platform charging 3% + $1.79/ticket takes $180 + $214.80 = $394.80 in platform fees. A flat $99/month plan with a 1% fee takes $99 + $60 = $159. You keep $235.80 more under the paid plan — more than twice the cost of the monthly subscription.

The break-even point varies by platform and ticket price, but for most nonprofits running ticketed events with 80+ attendees, a flat monthly subscription is the cheaper option.

What to Look for in a Free Tier

If you want to start free and grow, look for a platform where the free tier includes:

• Enough attendee capacity to run a real (small) event — 25 to 50
• Payment processing so you can test ticket sales, not just RSVPs
• Both free and paid events from the same account
• A clear upgrade path that does not require migrating to a new tool
• No annual contract on paid plans

CompleteEvent's free tier supports up to 25 attendees and one active event — enough to run a small free event and see whether the platform fits your workflow before upgrading. Start free — no credit card required.
