How to Do an Online Auction for Free

How to Do an Online Auction for Free: 7 Platforms Compared and Ranked

Did you know that several auction platforms now offer free plans that allow nonprofits, schools, churches and even community organizations to host fundraising auctions without paying upfront software fees?

The catch? "Free" doesn't always mean completely at no cost whatsoever.

Most platforms charge payment processing fees, others rely on optional donor tips, and some limit important features like mobile bidding, text-message notifications, reporting tools or auction customization unless you upgrade. So one way or another, there always does seem to be a fee of some kind.

Can You Really Run an Online Auction for Free?

Yes. You can run a professional online auction with $0 in upfront software costs. The best 100% free platform for 501(c)(3) nonprofits that do not need a robust set of tools is Zeffy, which uses a tip-based model to eliminate all fees. For organizations that need specialized features like "Soft Closes" or advanced mobile bidding, platforms like PayBee offer robust free tiers or "donor-covered fee" models.

Key Takeaways

• Truly free options exist, with a caveat. Platforms like Zeffy cover 100% of platform and credit card fees for nonprofits if the donor chooses to cover the cost of their donation, otherwise you are still on the hook if they don't.
• Understand the "Tip" model. Many free tools rely on optional donor tips rather than charging the organization. If donors decide not to cover you, you must pay the cost.
• Mobile bidding is essential. Over 90% of modern bidders participate via their smartphones. Often software providers charge more for mobile bidding options even though they are a 'must have.'
• Timing matters. End your auction on a Sunday evening to capture the highest volume of active bidders.
• Prioritize unique experiences. Items donors can't find on Amazon always outperform generic gift baskets.
• Automate your receipts. Choose a platform that handles tax-compliant receipts instantly after the auction ends. This will save you and your staff countless hours of unnecessary work.

Is It Really Free? Understanding the "Fine Print"

At the end of the day, every single software solution available today has costs, hard costs like staff, servers and processing fees. The money to pay for all of this must come from somewhere. Even Zeffy, a Certified B Corp based in Montreal, still looks to optional fees passed on to the donors. They do good by offering charities a way to possibly skip certain fees, but if your supporters don't feel like they want to also cover your costs on top of their donation, you are still responsible for the shortfall.

So is any platform truly free as in you are never required to pay a dime, not really. You need to understand that "free" usually falls into one of three buckets:

• The Tip-Based Model (Truly Free): Platforms like Zeffy or Givebutter charge the organization $0 if the donor chooses to take on the cost above their initial donation. At checkout, donors are asked to leave an optional "tip" to keep the platform running.
• The "Donor-Covered" Model: The software is free, but credit card fees (usually 2.9% + $0.30) apply. These types of software solutions are solid for some startups, but often lack any sophistication.
• The "Freemium" Model: You get the software for free up to a certain number of items or a certain dollar amount (e.g., PayBee's starter tier). Once you hit that limit or need advanced automation, you'll need to pay usually a monthly fee to unlock more solutions.

7 Free(ish) Online Auction Platforms Compared

Here's an honest breakdown based on features, real-user feedback, and suitability for nonprofits.

PayBee

Our software solution is best for organizations looking for a professional-grade start with the ability to scale into hybrid events, live-streaming and in-person check-in kiosks. We also offer real-time bidding, SMS/email notifications, auto features and blazing fast shopping carts for live events. And while you can use our platform totally free, you can sign up here, we do charge for our more sophisticated applications.

Zeffy

While the company does indeed give you the ability to take donations completely free of charge, there are a few caveats to think about. Zeffy funds itself through optional donor tips shown at checkout. So a donor gives $100 to your nonprofit, Zeffy suggests an additional tip (often pre-filled, sometimes around 10–17%), if the donor leaves the tip, Zeffy keeps that and your charity still gets the full $100.

We have found that some nonprofits that used Zeffy beforehand have stated that donors don't always realize the Zeffy tip is optional and the default tip can feel surprisingly high. In addition, some donors think your nonprofit added the extra charge and will sometimes lower their donation to offset the tip. So while their platform is solid for smaller charities, you really need to be aware of the trade-offs.

Many of our clients started with other platforms that offered free tiers, but quickly realized they needed more a professional tool suite and more professional looking branding for their organizations. And while we may not be the perfect fit for a small school fundraiser, although we can do that too, medium and large nonprofits thrive with our comprehensive solutions.

Givebutter

Givebutter is very similar to and often the alternative to Zeffy in that they sustain their work through optional tips. One thing that does make it different from Zeffy is that you can turn off the 'tips' if you don't want to burden your donors with the extra fees on top of their donations. But then it is no longer free as you would then need to pay the fees yourself.

The tip is pre-selected or prominently suggested and it can be easy to miss that part of their payment is going to Givebutter, not the nonprofit itself. Some donors have even cited feeling "tricked" when they notice later (especially on larger gifts, where the tip can be substantial). Think a $150 tip on a $1000 donation. But again, for small nonprofits their platform can be a solid starting point if you lack the funds to go all in on a more professional platform.

BetterWorld

Our next free(ish) contender is also similar to Zeffy and Givebutter in that they ask for tips to cover their costs. The exception here is they also tag on payment processing fees (~2.9% + $0.30). And while you can ask your donors to cover that too, if they refuse you are responsible for the fees. And if you disable donor tips, then you pay a 3% platform fee plus 2.9% + $0.30 processing fee for each donation received which can quickly add up to be more than just having a subscription to a more professional platform.

Beyond that, there are glitches in their software, especially for live events, so if you choose this route, please test your auction before it starts! A few smaller complaints include difficulty deleting accidentally duplicated events, image/photo formatting limitations and their dashboard navigation not always being intuitive according to reviews left on Capterra.

RallyUp

Like Givebutter, RallyUp's free model depends on donor tips, but a few differences matter. What seems better is donors can reduce or remove the tip and RallyUp explicitly says the tip goes to them, not your nonprofit. They say you won't be penalized if donors don't tip.

But payment processing fees still apply. Stripe/PayPal fees still apply and are usually 1.9%–2.9% + $0.30 per transaction. The sites states they don't mark these up, you pay exactly what the processor charges. So if someone donates $100, you might receive something like $96.80–$97.80, unless the donor chooses to cover the processing fee.

32auctions

32auctions is not "free free" in the same way as BetterWorld or RallyUp. It's more of a freemium auction tool, free for basic use, but with meaningful limits and/or fees depending on how you use it. They've long been known for offering a free online silent auction platform, especially for small nonprofits or school fundraisers. For a very small, simple auction, you may be able to use it without paying a subscription.

This is the important part, 32auctions charges around 2.9% + $0.40 per winning bid/payment, in addition to payment processing fees. That means if an item sells for $100, your total fees could look something like 32auctions fee: ~$3.30, payment processing: ~$3.20, total: ~$6.50 lost (6–7%). That's very different from platforms like BetterWorld or RallyUp, which often let donor tips subsidize the platform so your organization can potentially pay $0.

Furthermore, unlike Givebutter or Zeffy, 32auctions is mostly just for silent auctions. It usually doesn't replace donation forms, event ticketing, CRM/donor management, email marketing or other year-round fundraising tools. So even if the auction tool feels "free," you may need other paid tools alongside it.

CharityAuctionsToday

CharityAuctionsToday is not 'free' in the same way as BetterWorld or RallyUp. It's more of a pay-as-you-go auction platform that lets you start for free, but you'll almost always pay fees once money starts coming in.

Here's the honest breakdown, you can start for free (no subscription), that part is true. They advertise no upfront cost, no monthly subscription (on the Flex plan), no credit card needed to set up your auction and build your auction and only pay once items sell. So yes, you can create and launch without paying anything upfront.

But the 'free' Flex plan charges a 5% platform fee, a big difference from BetterWorld/Givebutter/RallyUp. So on their Flex plan, there's a 5% platform fee + 3% + $0.30 payment processing fee on top. That means total fees can be around 8%+ per transaction unless bidders cover some of them. That's not terrible for auction software, but it's definitely not zero-cost.

Step-by-Step: How to Set Up Your First Free Auction

Setting up an auction isn't rocket science, just use our list below and you'll have every aspect covered in the timeline it should happen.

1. Define Goals & Timeline: Set your fundraising target and auction length (7–14 days ideal for online), and decide on a date.
2. Choose & Sign Up for Platform: Pick a platform from our list that best fits your circumstances and verify your 501(c)(3) status for tax tools.
3. Procure Items: Focus on high value experiential items. (See PayBee's resource on silent auction ideas for inspiration.)
4. Add Items with Strong Details: Use high-quality photos, add detailed descriptions and a starting bid (20–30% of FMV) including increments (5–10%). If your platform choice has the option, add Buy-It-Now prices.
5. Configure Payments & Settings: Enable mobile/SMS bidding, bid extensions/soft close and tax receipt automation to save time and confusion.
6. Test Everything: Place test bids, check mobile view and payment flow.
7. Launch & Promote: Build buzz early via email and social media.
8. Monitor & Engage: Watch analytics and highlight hot items.
9. Close & Fulfill: Announce winners, collect payments, and send tax docs.
10. Analyze & Improve: Review reports for next time.

After you get your first auction completed, sit down and make some notes on what you experienced, what went well, what fell through the cracks. Making notes right away will guarantee that you'll be able to improve your results with each and every event you hold. These notes in themselves are truly gold, so use them to be consistently improving on each and every aspect of your fundraising.

Common Mistakes That Cost Nonprofits Money

• Ending During Business Hours: Never end an auction on a Tuesday at 2 PM. End it on a Sunday evening between 7 PM and 9 PM when people are on their couches with their phones.
• Auctioning "Common" Items: If I can buy it on Amazon for $50, I won't bid $60. Prioritize unique experiences.
• No Mobile Bidding: Mobile bidding and strong promotion can boost your results by 30–50%+!
• Ignoring "Soft Closes": Without bid extensions, 'sniping' reduces your final total.
• Starting bids too high: High opening bids suppress participation and pretty much stops momentum. Momentum matters more than maximizing the first bid.
• Poor promotion: Many nonprofits spend weeks collecting items and only days marketing them to their supporters, yet the promotion often determines your success more than the inventory.
• No bidder follow-up: After the auction is just as important as the auction itself. Always reach out to successful bidders and thank them for their support. Make sure you send out a thank you email within 24 hours of any event.

FAQ: Frequently Asked Questions

Do you need a 501(c)(3) to use free auction software?

For Zeffy, yes. For platforms like 32auctions or BetterWorld, individuals or "unincorporated" clubs can often use the software, though tax receipting won't be available.

How long should an online auction run?

The sweet spot is 7 to 10 days. Any longer and donors lose interest while any shorter and you don't give enough time for the 'bidding war' to escalate.

Is it actually possible to run an online auction for $0?

Yes. You can run a professional auction with no upfront software costs by using platforms with "tip-based" models or "free tiers." However, keep in mind that payment processing fees or donor tips usually apply.

Why is mobile bidding considered essential?

Over 90% of modern bidders use their smartphones. Platforms that lack mobile bidding or charge extra for it can significantly hinder your auction's success and participation rates.

What is a "Soft Close" and why does it matter?

A 'Soft Close' (or bid extension) prevents sniping by extending the auction time slightly if a bid is placed in the final moments. This gives your organization the best chance of reaching the highest possible price for an item.
