Neither platform charges a platform fee on its free plan. The difference is the card fees: RallyUp takes them out of what you raise on both plans, and Zeffy covers them.
Zeffy is trusted by 100,000+ not-for-profits
💰
RallyUp's free plan has no platform fee, and its nine Core Components cover most of what a not-for-profit runs. Switch donor tipping off and you move to Flex, where the fee is set per Component from 2.9% to 6.9%. With Zeffy there is no second plan, no platform fee, and no card fee either, because Zeffy covers the processing.
🎟️
Live Auctions, Silent Auctions, Fund-a-Need, Paddle Raise+ and Event Balances are Flex-only on RallyUp, so a gala pushes you onto the paid plan. Zeffy includes its event tooling on the only plan it has.
🧾
RallyUp publishes Donor Profiles plus CRM and email integrations, and memberships do not appear in its Fundraising Portfolio at all. Zeffy includes memberships, a donor CRM and email in the same place you fundraise.
Yes, on its Free plan. RallyUp charges no platform fee on that plan and says you will never pay one "even if no donors tip". It is funded by an optional donor tip at checkout, and on Raffles and Sweepstakes donors are offered discounted bonus entries which are treated as tips. Card processing fees are a separate matter and still apply: in RallyUp’s words, "All transactions incur payment processing fees, regardless of pricing plan", at 1.9% to 2.9% plus $0.30, and only Flex lets you pass them to donors. Zeffy works the same way on the platform fee and covers the processing as well, so your organisation receives the full amount.
You move to the Flex plan, where a platform fee is deducted from the funds you raise and is set per Component: 2.9% on Ticketing & Registration and Storefront, 4.9% on Auctions, Crowdfunding, Fund-a-Need, Paddle Raise+ and A-Thons, and 6.9% on Raffles and Sweepstakes. Livestreaming and Donation Pages carry no fee. If you run two Components in one Campaign, each is charged at its own rate. With Zeffy there is no equivalent trade-off: the platform is free whether or not donors contribute.
Yes. RallyUp caps the platform fee on any auction item at $100 no matter how high the winning bid, and gives the example of a car sold for $55,000 still costing $100. That is a genuinely good term for high-value lots. Zeffy charges nothing on auction items at any value.
The organisation does, and they go to the processor rather than to RallyUp. Their words: "RallyUp does not receive any portion of the payment processing fees, and we do not add any charges for payment processing." They quote Stripe or PayPal at 1.9% to 2.9% plus $0.30 depending on your own arrangement, and on Flex you can pass those fees to donors. Zeffy covers processing itself, so your organisation receives the full donation.
No. RallyUp publishes no contracts, subscriptions, up-front fees, setup fees, consulting fees or minimum fees. One paid extra exists: a custom domain for a one-time $99. Your plan does lock once a Campaign goes live, though you can use different plans for different Campaigns.
Memberships do not appear anywhere in RallyUp's published Fundraising Portfolio, which lists Raffles, Online Auctions, Sweepstakes, Ticketing & Registration, Crowdfunding, Peer-to-Peer, A-Thons, Storefront and Livestreaming as Core, and Live Auctions, Silent Auctions, Fund-a-Need, Paddle Raise+, Event Balances, Automated Checkout and Live Display as Flex-only. Zeffy includes memberships with no per-member fee.
Yes. RallyUp lists Australia among 33 supported countries and AUD among more than 135 currencies. Eligible organisations are registered charities, NGOs, schools, religious organisations and community groups, and personal-cause fundraising is excluded. Zeffy is available to registered Australian not-for-profits with an ABN and ACNC registration.
RallyUp runs Raffles and Sweepstakes, and Zeffy does not offer raffles to Australian organisations. It also has A-Thons, Livestreaming, Live Display and Done-for-you services where one of its fundraising experts plans, builds, reviews or finishes a campaign for you. If any of those is the centre of your fundraising year, RallyUp is worth a look on its free plan.
Zeffy is the fundraising platform that cuts out the fees, clears up your tech mess, and puts your cause first, so your team, even if you're a small team wearing many hats or a one-person show, can focus on what really matters.
No platform fees. No processing fees. No catch. We know it sounds too good to be true, but it's not. Every cent goes straight to your cause, while competitors take 2-3% off every donation.

Built for teams like yours, whether you're volunteer-led or have limited staff. Set up donation forms, sell tickets, and launch campaigns without needing a tech wizard. It's super easy, and you'll be up and running in minutes.


From QR codes on flyers to Tap-to-Pay on a phone, Zeffy makes it easy to accept donations on the go. Mobile-optimized and offline-ready, so no donor slips through the cracks.
Centralize supporter relationships, automate thank-you messages, and preserve institutional knowledge when board members rotate out.

As a startup nonprofit with only two members, and no funding (yet) we’d need something with low (or no) fees. Zeffy was a dream come true.
