Choosing a fundraising platform is one of those decisions that looks technical and is actually strategic. The platform you pick determines how easily supporters can give, what data you own, what fees quietly leave with every donation, and how painful your life becomes when you eventually want to move. It is a little like choosing a bank, if banks also hosted your birthday party and kept a copy of your address book.
This guide compares the main categories of platform and the leading names within them, with a professional fundraiser's eye on the questions that matter: total cost of giving, data ownership, supporter experience, and integration with the rest of your programme. One honest disclaimer before we begin: platform fees and features change frequently, so treat the fee models described here as how to think about pricing rather than a permanent price list, and always confirm current rates on the platform's own pricing page before signing anything.
The four questions that matter more than any feature list
Platform demos are seductive. Before you watch one, write these four questions on a sticky note.
1. What is the total cost of a donation? Platforms charge in combinations of subscription fees, platform percentage fees, and payment processing fees, sometimes offset by optional donor tipping or fee-cover prompts. A "free" platform funded by donor tips is not free; it is funded by your donors, and the tip prompt is part of their giving experience whether you like its wording or not. Model the true cost on your actual gift profile: a platform that costs less on £20 gifts may cost more on £2,000 ones.
2. Who owns the donor data, and in what form? The difference between receiving full donor records (name, email, consent status, gift history) and receiving a monthly lump sum with partial data is the difference between building a fundraising programme and renting one. Facebook's giving tools historically demonstrated the problem: enormous sums raised, with charities often unable to identify, thank or retain the people behind the money. Any platform decision should start with what appears in your CRM afterwards.
3. Does it handle recurring giving properly? Monthly donors are the sector's most valuable asset. Check how the platform manages card expiry and payment retries, whether donors can self-manage their gift, and, critically, what happens to your regular givers if you leave the platform. Some platforms allow migration of recurring payment tokens; others effectively hold your monthly donors hostage. Ask the awkward question before you sign, not after.
4. What happens at your peak? Your platform earns its keep in the last week of a tax appeal or on the day your emergency campaign goes viral. Ask about uptime history, payout speed (days matter in a cashflow crisis), and support responsiveness on weekends. A platform's true personality emerges at 9pm on deadline day.
Category one: donation pages and forms (your everyday engine)
This is the core infrastructure: the donation experience embedded in your own website for single and regular gifts.
Donorbox has become a default for small and mid-sized charities worldwide: quick to deploy, embeddable, strong recurring giving options, and a fee model combining a modest platform percentage with payment processing, offset by optional donor tipping on some tiers. Its strength is speed to launch; its limits appear when you want deep customisation or complex journeys.
Funraisin and Raisely (both Australian-born, now international) sit at the more design-led end, offering fully branded donation and campaign experiences. Raisely made its name with a generous free-tier model funded by optional donor contributions and has been popular with charities of every size wanting beautiful pages without developer time. Funraisin is the heavyweight for organisations that want their donation and event experiences to feel completely owned, and powers many of the major challenge events in Australia and beyond.
Enthuse in the UK positions itself explicitly on the data question: donor relationships and branding stay with the charity rather than the platform, a direct contrast with marketplace models. It has grown by winning charities that tired of renting their own supporters back.
CRM-native forms (the donation modules inside Salesforce-based tools, Blackbaud products, Infoodle, and similar) trade elegance for integration. If your organisation lives inside a major CRM, a slightly less beautiful form that writes perfect records automatically may beat a gorgeous one that requires weekly CSV imports and a prayer.
The strategic note for this category: conversion rate differences between a mediocre and an excellent donation experience are large enough to outweigh fee differences entirely. A platform costing one percentage point more that converts 20 per cent better is not more expensive; it is dramatically cheaper. Test the mobile experience of any shortlisted platform with your own thumbs before deciding.
Category two: peer-to-peer and events platforms
If challenge events, community fundraising or appeals with fundraiser pages are part of your programme, this category is where platform choice most directly drives revenue, because the product being optimised is not a form but a fundraiser's motivation.
JustGiving remains the UK's household name, with the enormous advantage that supporters already trust it and often already have accounts. Its fee model has shifted over the years between platform fees and donor-tip funding, so check current terms. The trade-off for its ubiquity is a more standardised experience and a brand that sits alongside your own.
Funraisin, Raisely and Grassrootz power branded challenge events (the 100km-style virtual challenges, community walks, and signature events) where the charity controls the whole experience: registration flow, fundraiser coaching emails, leaderboards, team mechanics and integrations. For organisations running serious P2P programmes, capabilities like automated fundraiser nudges and Strava-style activity integration are not nice-to-haves; they are the difference between a 40 per cent and a 70 per cent activation rate (the share of registrants who raise anything at all), which is the metric that actually decides P2P revenue.
GoFundMe dominates consumer crowdfunding and offers charity modes in several markets, having also absorbed various charity-focused tools over the years. Its strength is reach and familiarity for supporter-led fundraising; its weakness for charities is the same as every marketplace: the relationship risks living with the platform. Sensible use: meet supporters where they already fundraise, and work hard to bring the relationship home afterwards.
Facebook and Instagram fundraising tools deserve mention as the largest P2P engine most charities do not control. Billions have been raised through birthday fundraisers at zero platform cost, which is genuinely wonderful, with the persistent caveat that donor data is minimal. The professional consensus has settled on: enable it, celebrate it, and never let it substitute for channels where you can actually say thank you.
Category three: campaign and crowdfunding platforms
For time-limited, target-driven campaigns (a capital project, an emergency appeal, a giving day), the specialist crowdfunding features matter: live totals, matched-funding mechanics, stretch goals and campaign updates.
The Big Give occupies a unique UK position: a match-funding platform whose Christmas Challenge doubles donations through pooled champion funds, channelling tens of millions annually. If you are a UK charity, applying for its match windows is less a platform decision than a fundraising strategy in itself.
Chuffed built its reputation on social-cause crowdfunding, popular with smaller organisations and grassroots campaigns, with a donor-contribution funding model.
GoFundMe and JustGiving campaign pages serve the same need with maximum public familiarity, which matters when your campaign depends on strangers trusting the payment page.
The category rule: crowdfunding platforms excel at moments and struggle as homes. Run the campaign where the features and audience live; steward the donors somewhere you control. Our companion article on charity crowdfunding covers when these campaigns work and when they quietly flop.
Category four: the enterprise stack
Large organisations typically stop asking "which platform" and start asking "which architecture": a CRM at the centre (Salesforce Nonprofit Cloud, Blackbaud Raiser's Edge NXT, Microsoft Dynamics), donation and event experiences from the platforms above feeding into it, and a payments layer (Stripe, Braintree, GoCardless for direct debit) underneath. At this scale the platform questions become integration questions: does the tool write clean records, respect consent fields, pass Gift Aid declarations, and survive your data team's scrutiny?
The enterprise trap worth naming: capability sprawl. Many large charities operate five or more giving tools acquired by different teams over different years, each with its own fees, data gaps and password spreadsheet. An annual platform audit, with a licence to kill redundant tools, is unglamorous and reliably lucrative.
A decision framework by charity size
Small charities (under roughly £1m income). Optimise for speed, low fixed cost and data ownership. A modern form tool (Donorbox, Raisely or similar) embedded in your site, plus JustGiving or GoFundMe presence for supporter-led fundraising, covers 95 per cent of needs. Avoid anything with a chunky monthly subscription until your volume justifies it, and avoid any tool that cannot export your full donor data on demand.
Mid-sized charities. Your inflection point is recurring giving and P2P. This is where investing in a branded events platform typically pays for itself in activation-rate improvements, and where CRM integration stops being optional. Budget real time for the migration; the platforms make it sound like an afternoon, and it is never an afternoon.
Large charities. Your questions are architectural: data flow, consent management, payment redundancy, and exit costs. Negotiate fees (enterprise pricing is always negotiable, whatever the rate card implies), demand roadmap transparency, and keep at least one alternative warm. Platform dependence is a strategic risk like any other, and the time to think about leaving is before you need to.
The fine print checklist
Before any contract is signed, obtain written answers to these:
- All fees, itemised: subscription, platform percentage, processing, payout, and any charges on refunds or chargebacks
- Exactly which donor data fields you receive, in what format, how often
- Recurring donor portability: can payment tokens migrate if you leave?
- Gift Aid handling, automated or manual
- Payout timing, and what happens during platform insolvency (donation funds should be held in trust or safeguarded; ask how)
- Support hours, and what "support" means on the final weekend of your biggest appeal
A platform that answers these promptly and plainly is telling you something valuable. So is one that does not.
The perfect platform does not exist; the right platform for your programme, this size, this strategy, these supporters, absolutely does. Choose it on data, total cost and supporter experience, revisit the choice every couple of years, and never confuse the plumbing with the point: platforms process generosity, but people create it, and they respond to your cause, not your checkout provider.
