The best nonprofit fundraising software depends on the organization’s primary need. Zeffy is a strong fit for eligible nonprofits prioritizing zero platform and processing fees; Givebutter combines fundraising, donor records, and communications in a free core platform; Donorbox focuses on donation forms and recurring giving; Little Green Light provides an affordable donor CRM; Bloomerang connects fundraising with deeper supporter management; Fundraise Up emphasizes online-donation conversion; Salesforce Nonprofit Cloud supports complex, configurable operations; and BiddingOwl specializes in auctions and fundraising events.
Fundraising software is not one type of product. The term can refer to a donation-form platform, donor database, constituent relationship management system, peer-to-peer fundraising tool, event platform, auction system, email and automation suite, or an enterprise system that combines several of those functions.
That distinction matters. A nonprofit may choose excellent donation software and still need a donor CRM. A powerful CRM may still require a separate tool for online giving or auctions. An auction platform may manage bidders, items, invoices, and event payments without replacing the organization’s year-round donor database.
This guide compares eight nonprofit fundraising platforms by their primary purpose, pricing approach, donor experience, data-management capabilities, fundraising tools, integrations, implementation needs, and best-fit organization.
Disclosure: This comparison is published by BiddingOwl, which is included as an auction and event-fundraising specialist. No provider paid for placement. Product details and pricing were reviewed using current official provider materials. Terms can change, so verify current information directly with each company before making a purchasing decision.

These are best-fit categories rather than universal rankings. A nonprofit may use one platform as its primary database and another for a specialized function such as auctions, peer-to-peer fundraising, wealth screening, accounting, or marketing automation.
Nonprofit fundraising software helps an organization collect gifts, maintain supporter information, communicate with donors, operate campaigns, and measure results. Depending on the product, it may include:
| Software category | Primary job | Typical limitation |
|---|---|---|
| Online fundraising platform | Donation forms, campaign pages, recurring gifts, peer-to-peer fundraising, events, and payments | May provide lighter long-term relationship management than a dedicated CRM |
| Donor CRM | Central supporter records, gift history, households, segmentation, tasks, acknowledgments, and reporting | May require a separate donation, event, auction, or marketing tool |
| Enterprise nonprofit CRM | Configurable fundraising, programs, services, grants, volunteers, and organization-wide data | Can require significant implementation, administration, training, and consulting |
| Donation-conversion platform | Optimizes online giving, payment methods, recurring gifts, and checkout completion | Often complements rather than replaces the organization’s CRM |
| Auction and event-fundraising software | Items, bidders, bids, winners, invoices, event payments, and auction reporting | Usually does not replace a complete year-round donor CRM |
Before comparing brands, decide which category the organization needs. A team searching for better donation conversion should not evaluate products using the same checklist as a team replacing a donor database.
Each provider was reviewed using the following criteria:
Zeffy is a nonprofit-only fundraising platform offering donation forms, events, auctions, raffles, memberships, peer-to-peer fundraising, online sales, payments, email, and contact management.
Zeffy states that eligible nonprofits pay no platform fees, monthly subscriptions, per-user charges, payout fees, or credit-card processing fees. The nonprofit receives the full intended payment.
The service is funded through an optional contribution offered to supporters at checkout. The supporter can decline or adjust the contribution, but Zeffy controls the contribution wording and suggested amount.
Best fit: Eligible nonprofits that want donation forms, events, campaigns, basic CRM, and payment processing without direct platform or processing costs.
For a detailed auction comparison, see BiddingOwl vs. Zeffy.
Givebutter combines fundraising pages, events, auctions, peer-to-peer campaigns, donor records, email, texting, and engagement tools.
Givebutter provides its core fundraising platform and CRM without a monthly subscription. When optional tips are enabled, its published model can provide 0% platform and processing fees for qualifying transactions under the Givebutter Guarantee.
If optional tips are disabled, a 3% platform fee applies plus standard payment processing. Certain auction winner-charging methods are also priced differently.
Givebutter Plus adds advanced automation, analytics, marketing, and productivity features. Current published pricing starts at $29 per month and increases with contact count and selected billing frequency.
Best fit: Small and midsized nonprofits that want fundraising, events, campaigns, communications, and a free core donor CRM in one approachable platform.
For an auction-specific comparison of the two platforms, read BiddingOwl vs. Givebutter.
Donorbox focuses on online fundraising forms, recurring giving, peer-to-peer campaigns, crowdfunding, memberships, events, and donor-management tools.
Donorbox’s Standard plan has no monthly subscription. Its current pricing page publishes platform fees between 2.95% and 3.95% depending on the fundraising product, in addition to payment-processing charges.
Donorbox Pro currently starts at $150 per month with discounted annual billing. It lowers platform fees to approximately 1.75%–2% and adds advanced features. Premium pricing is customized.
Best fit: Small and growing nonprofits that prioritize flexible donation forms, recurring giving, peer-to-peer fundraising, and event forms without beginning with a large annual contract.
Little Green Light is donor-management and CRM software designed for small and midsized nonprofit organizations.
Little Green Light publishes all-inclusive monthly pricing based on constituent count:
The company states that there are no setup fees, cancellation fees, contracts, or feature upsells. Prepayment discounts are available.
Best fit: Small and midsized nonprofits moving beyond spreadsheets and needing an affordable, established donor database with gift tracking, acknowledgments, reporting, and integrations.
Bloomerang provides fundraising, donor CRM, volunteer engagement, event tools, reporting, and supporter intelligence in a connected platform.
Bloomerang pricing is based on the number of records and the products selected. Its current pricing page publishes the connected Giving Platform starting at $242 per month, billed annually. Individual fundraising, CRM, volunteer, event, and related configurations may be priced differently.
Best fit: Growing nonprofits that need connected fundraising and deeper donor management, have an established development process, and can support a larger annual software investment.
Fundraise Up is focused on optimizing the digital donation experience rather than serving as a traditional all-purpose donor CRM.
Fundraise Up currently publishes a 4% transaction fee plus Stripe or PayPal payment-processing charges. It states that there are no subscriptions, setup fees, contracts, or paid feature tiers.
Best fit: Nonprofits with meaningful online-giving volume that prioritize checkout conversion, recurring gifts, personalization, donor payment choice, and CRM integration.
Salesforce Nonprofit Cloud is a configurable CRM platform for fundraising, stakeholder relationships, programs, case management, grants, volunteers, marketing, analytics, and organization-wide operations.
Salesforce’s Power of Us program offers eligible nonprofits access to 10 free Salesforce licenses for qualifying products. Additional licenses, clouds, storage, marketing tools, analytics, applications, implementation, administration, and consulting can add significant cost.
Best fit: Midsized and large organizations with complex data, workflow, integration, reporting, or cross-department requirements and the internal or consulting resources to administer the system.
BiddingOwl is specialized fundraising software for charity auctions and auction-centered events. It should be evaluated differently from a donor CRM or general donation-form platform.
BiddingOwl does not charge a standard monthly or setup fee. A 5% performance fee applies to winning online and mobile bids. Traditional silent and live auction tools, paper bid sheets, tickets, donations, Fund-a-Need, and paddle raises are not subject to that performance fee. Stripe or PayPal processing remains separate.
Best fit: Nonprofits, schools, churches, clubs, rescues, museums, libraries, and community groups that need auction and event-fundraising tools without purchasing a large annual auction license.
Review the auction software buyer’s guide, silent auction platform comparison, and silent auction fees guide.

We also have a detailed overview for auction-platform alternatives.
The source of truth is the system that holds the organization’s authoritative supporter record. Decide whether the new platform will be:
Without this decision, the organization can end up with duplicate donor records and conflicting gift totals across several tools.
Document current and planned revenue from:
Do not pay for sophisticated tools the organization will not use, but do not select a platform that cannot support the revenue streams driving the mission.
Test how a supporter will:
Also test how staff will:
Include:
Use the same annual donation volume, transaction count, contact count, event revenue, and required features for every provider.
Confirm:
The development team may prioritize donor history and acknowledgments. Finance may need deposits, fees, refunds, and accounting exports. Communications may need segmentation and email. Event staff may need tickets, check-in, auctions, and mobile payments.
Document these requirements before vendor demonstrations.
Use a trial, sandbox, test campaign, or guided demonstration to complete common tasks. Avoid evaluating only the public donation page or a vendor’s prepared presentation.
A beautiful giving page does not solve duplicate records, household relationships, major-gift tasks, acknowledgments, or organization-wide reporting.
Powerful configuration is valuable only when the organization can implement, document, maintain, and train people on the system.
Include processing, contact tiers, implementation, integrations, premium features, support, and internal staff time.
Ask exactly which fields synchronize, in which direction, how often, and what happens when records do not match.
Test checks, cash, pledges, refunds, chargebacks, stock gifts, matching gifts, and corrections—not only online card donations.
Old databases often contain duplicates, inconsistent names, missing addresses, obsolete codes, and undocumented custom fields. Cleaning the data is part of the project.
A well-connected technology stack may be more effective than one product that performs several critical functions only adequately.
There is no universal best platform. Zeffy may be best for an eligible nonprofit prioritizing no platform or processing fees. Givebutter may be best for a free core all-in-one platform. Donorbox may fit donation-form and recurring-gift needs. Little Green Light may be best for an affordable donor CRM. Bloomerang may suit a growing development program. Fundraise Up may fit high-volume digital giving. Salesforce may support complex enterprise operations. BiddingOwl may be best for auction-centered fundraising.
Fundraising software helps collect gifts and run campaigns. A donor CRM maintains the long-term record of supporter relationships, gifts, interactions, tasks, households, and communications. Some platforms combine both functions, while others specialize.
Zeffy charges eligible nonprofits no platform or processing fees and is funded through optional supporter contributions. Givebutter provides free core fundraising and CRM tools, with optional tips affecting the fee structure. The best choice depends on eligibility, donor checkout preferences, campaign types, CRM depth, and integrations.
Little Green Light is a strong affordable option for organizations that need donor records, gift tracking, acknowledgments, reports, forms, and integrations. Givebutter and Zeffy may be suitable when a free fundraising platform with contact management is sufficient. Test the organization’s exact reporting and stewardship workflow.
Donorbox, Fundraise Up, Givebutter, and Zeffy all support recurring gifts. Fundraise Up emphasizes optimized checkout and recurring-gift conversion. Donorbox focuses heavily on donation forms and recurring giving. Compare donor self-service, failed-payment recovery, fees, CRM integration, and reporting.
BiddingOwl specializes in online, mobile, paper, silent, live, and hybrid auctions, along with tickets, donations, Fund-a-Need, and paddle raises. Other broad fundraising platforms also offer auctions, but the paper, live, payment, support, and item-management workflows differ.
Yes. A nonprofit may use one system as its primary donor CRM and connect specialized tools for donation optimization, auctions, events, email, accounting, wealth screening, or peer-to-peer campaigns. The organization should document which system is the source of truth and how data moves between tools.
Costs may include monthly subscriptions, contact-based tiers, platform percentages, payment processing, fixed transaction charges, optional supporter contributions, implementation, migration, training, integrations, messaging, and support. Compare annual total cost using the same fundraising volume and requirements.
Transaction pricing can reduce upfront cost but become expensive as volume grows. A subscription can be more predictable but may not be economical for a small or occasional fundraiser. Model both options using actual or expected annual revenue and transaction counts.
Test a one-time donation, recurring gift, receipt, refund, offline gift, contact search, duplicate merge, acknowledgment, segmentation, campaign report, export, and integration. For events or auctions, also test registration, bidding, winner payment, and reconciliation.
Choose nonprofit fundraising software based on the work the organization must perform every week—not the longest feature list or the most attractive headline price.
Zeffy may provide the lowest direct cost for an eligible nonprofit comfortable with optional supporter contributions. Givebutter may provide the strongest free core combination of fundraising, donor records, events, and communication. Donorbox may fit organizations prioritizing donation forms and recurring gifts. Little Green Light may offer the most approachable route from spreadsheets to a dedicated donor CRM. Bloomerang may suit a growing development operation ready for a connected giving platform. Fundraise Up may be valuable where online-donation conversion and recurring revenue justify transaction-based pricing. Salesforce Nonprofit Cloud may support complex, configurable organization-wide operations. BiddingOwl may be the strongest specialized choice when auctions and fundraising events are central.
Before committing, identify the source of truth, calculate the full annual cost, test real donor and staff workflows, confirm data portability, and involve fundraising, finance, communications, and operations in the decision.
