Picking a donor database is one of the higher-stakes software decisions a small nonprofit makes. Once you train your team and migrate your records, switching again is painful, so the choice has to hold up for a few years.

This guide is written for the volunteer treasurer or executive director who is also the fundraiser, working with under 5,000 donors and a budget closer to $0 than $500/month. We compared the 8 most common donor databases on the criteria that actually matter for that segment: real annual cost, setup without IT support, whether the donation form auto-writes to the donor record, how pricing scales as you grow, and built-in tax-receipt automation.

The 8 best donor databases for small nonprofits in 2026

1. Zeffy — Best free donor database for small nonprofits

G2: 4.9/5 Pricing: $0 (no subscription, no platform fees, no transaction fees)

Zeffy's free donor management software is the only donor database that is actually free at every donor-count tier. Over 100K+ nonprofits have used Zeffy to raise more than $2B, keeping 100% of what they raise. Donations, ticketing, peer-to-peer, auctions, and donor records share one record system in one login, so there's no double data entry between a payment processor and a CRM.

Best for: Small and mid-sized nonprofits (under 5,000 donors) that need to get up and running quickly, keep every dollar raised, and manage fundraising without a dedicated database manager.

Small nonprofit fit: The strongest match for 1–3-person or volunteer-run teams operating under a $100/month budget. $0 at every donor-count tier means the cost never becomes a reason to switch.

Top features:

• Auto contact updates — every donation or ticket purchase writes back to the donor record

• Segmentation, tagging, and notes on every donor profile

• Pre-filled donation forms that auto-update donor records (no double data entry)

• Send segmented emails from the same dashboard instead of paying for a separate Mailchimp

• Automatic tax-receipt generation on every gift, IRS-compliant and branded

• Full suite of campaigns: donations, ticketing, P2P, auctions, raffles, e-commerce, memberships

Pros: Truly $0 at 500, 1,000, 2,500, and 5,000 contacts; nonprofit-native; receipts and donor management built in.

Caveats: No wealth screening, no enterprise moves-management, no volunteer-hours tracking module. If your stewardship workflow centers on those, Bloomerang or Little Green Light is a closer fit.

Is Zeffy's free model actually sustainable?

This is the question most small nonprofits ask before switching. The answer hasn't changed since 2023: Zeffy is funded by optional tips from donors. On average, 2 out of 3 donors leave a tip, which covers all costs and reinvests in the platform. Donors are never forced to tip — if they don't, the nonprofit still keeps 100% of the money raised.

The Twin Steeples Foundation moved from Bloomerang ("Bloomerang plans start at $125 every month") to Zeffy after running both side by side. Community Music School of Santa Cruz switched after their previous "free" platform eliminated free accounts — a pattern enough small nonprofits have hit that it's worth planning around upfront.

When our last donor management system eliminated free accounts, we couldn't afford to continue with them.

With Zeffy, they give $100, you get $100. With every other platform on this list, they give $100 and you get $97 or less after fees.

2. Bloomerang — Best for donor retention and stewardship depth

G2: 4.7/5 Pricing: starts at $125/month

Bloomerang is the strongest paid pick when stewardship depth matters more than budget. The engagement meter and wealth-screening add-ons are genuinely useful if you have the staff capacity to act on them.

Best for: Established orgs that want a polished engagement meter, wealth-data layer, and dedicated stewardship workflow — and can absorb $1,500+/year in subscription before processing fees.

Small nonprofit fit: Not ideal for teams under 3 staff or budgets under $100/month — the $125+/month subscription is the main barrier. Worth it only when your donor stewardship has grown complex enough to need wealth screening and engagement timelines.

Top features: engagement meter, wealth screening, visual donor timelines, campaign dashboards, unified online giving (Kindful was absorbed in 2021).

Pros: Best-in-class retention analytics; intuitive dashboard; IRS-compliant receipts included.

Caveats: $125+/month before Stripe processing (~2.2% + $0.30); pricing escalates by record count; real ramp to a populated engagement meter is 2-4 weeks.

‍

‍

3. GiveLively — Free, but membership is gated

Pricing: $0 subscription; ~1.99% + $0.25 processing via Stripe/Shift4

GiveLively is also $0-platform-fee, funded by donor tips, but membership is gated by a values-alignment review. If your org clears the application, it's a solid choice with a narrower feature surface than Zeffy (no ticketing, auctions, raffles, or e-commerce).

Best for: Mission-aligned nonprofits that pass GiveLively's review and only need donation forms plus a basic donor record.

Small nonprofit fit: A viable $0 option for small teams if you clear the membership review — but the gated application and narrower feature set make Zeffy the lower-friction default for most 1–3-person teams.

Pros: Free at every donor-count tier; IRS-compliant receipts included.

Caveats: Application can take time and isn't guaranteed; donation-only feature surface (no events, auctions, P2P parity with Zeffy).

‍

4. DonorPerfect — Best for established orgs with dedicated staff

G2: 4.4/5 Pricing: starts at $99/month (Core); Plus and Pro custom-quoted

DonorPerfect is built for established organizations with large donor databases and dedicated staff. Zeffy is built for small nonprofits — these tools serve different segments, and DonorPerfect is overkill for a volunteer-led team under 5,000 donors.

Best for: Multi-branch or national nonprofits with 5,000+ donors, complex segmentation needs, and a budget for $99+/month.

Small nonprofit fit: Not a match for 1–3-person teams or budgets under $100/month. The $99+/month starting price, required sales call for higher tiers, and CRM-first architecture are sized for organizations with dedicated fundraising staff.

Top features: targeted segment messaging, real-time updates, automatic address refresh, instant duplicate detection, mobile access.

Pros: CRM-native with deep customization; receipts and acknowledgements included.

Caveats: Sales call required for Plus/Pro tiers; processing around 2.89% + $0.30 layered on subscription; online giving feels bolted onto a CRM rather than form-first.

‍

‍

5. Donorbox — Same-day donation forms with a 5% effective load

Pricing: $0 subscription on Standard; ~5.15% + $0.30 effective per gift (2.95% platform + 2.2% Stripe). Pro $150/mo; Premium contact-sales.

Donorbox publishes same-day, no demo required — the same low-friction setup as Zeffy. The difference is the 2.95% platform fee stacked on Stripe's 2.2% + $0.30, which lands around 5% effective. Zeffy eliminates that load entirely.

Best for: Orgs that already use Donorbox and want a familiar form-first donation tool with a built-in donor list.

Small nonprofit fit: The $0 subscription makes it accessible for small teams, but the ~5% effective fee per gift adds up quickly for orgs under a tight budget — Zeffy's $0 effective cost is a meaningful advantage at any donor volume.

Pros: No subscription on Standard; same-day publish; receipts included.

Caveats: ~5% effective fee per gift on Standard; Pro upsell at $150/mo is the standard growth path; lighter than a true CRM.

‍

6. Neon One CRM — Mid-market CRM with membership and volunteer modules

G2: 4.3/5 Pricing: starts around $139/month (verify on Neon's pricing page before signing)

Neon One offers CRM, fundraising, membership, and volunteer modules in one stack. The user-centric dashboard and engagement timeline are well-built; the price is the deciding factor for small teams.

Best for: Mid-sized nonprofits juggling donors, members, and volunteers across campaigns who want it all in one platform.

Small nonprofit fit: The ~$139/month starting price exceeds what most 1–3-person teams or volunteer-run orgs can justify. Best suited to nonprofits that have outgrown simpler tools and have staff to manage multiple modules.

Pros: 40+ pre-built reports plus custom dashboards; membership portal; workflow automation.

Caveats: Subscription cost is the main barrier for small teams; tier escalations as features unlock.

‍

‍

7. HubSpot for Nonprofits — Free general CRM, not nonprofit-native

Pricing: Free CRM tier; 40% nonprofit discount on paid hubs

HubSpot's free CRM is real and the 40% nonprofit discount on paid hubs is meaningful. The catch: it's a marketing and sales CRM repurposed for nonprofits — it doesn't generate IRS-compliant tax receipts, doesn't have donation forms out of the box, and doesn't think in donations.

Best for: Nonprofits that already run marketing on HubSpot and want a donor list inside their existing stack — paired with a separate donation tool.

Small nonprofit fit: Only a fit for small teams already embedded in the HubSpot ecosystem. For orgs starting from scratch, the absence of built-in receipts and donation forms means you'll need a second tool, which adds friction and cost.

Pros: Mature CRM; free tier is genuinely usable; large ecosystem.

Caveats: No built-in receipts or donation forms; you'll need a second tool for fundraising.

8. Blackbaud Raiser's Edge NXT — For universities and legacy orgs

G2: 3.9/5 Pricing: custom-quoted, typically $10K+/year

Raiser's Edge NXT is enterprise-tier software built for universities, hospital foundations, and legacy organizations with complex donor portfolios and dedicated development teams. It is not designed for a 1-3 person nonprofit.

Best for: Large organizations managing major gifts, planned giving, and intricate donor journeys with multiple staff on the database.

Small nonprofit fit: Not a match — custom contracts, $10K+/year pricing, and months-long implementation make this a poor fit for any team under 5,000 donors without a dedicated database staff.

Pros: Deep portfolio management; secure reporting; tailored annual reports; mature donor portals.

Caveats: Custom contracts; lowest G2 score on this list (3.9/5); implementation is measured in months.

Most platforms charge a subscription, a platform fee, or both. Zeffy eliminates those costs entirely.

How to choose the right donor database

Use these five criteria — the same ones we used to evaluate every tool above — to narrow your shortlist. They're framed specifically for the most common small nonprofit profile: a 1–3-person or volunteer-run team, a donor list under 5,000, and a budget under $100/month.

• 1. Annual cost at your donor count — budget under $100/month. Add up subscription + platform fee + processing. Many tools quote the subscription only; the all-in cost at 1,000 donors is usually 2-3x the headline number. For teams operating under $100/month, only Zeffy, GiveLively (if admitted), and HubSpot's free CRM clear that bar — and only Zeffy includes built-in donation forms and receipts.

• 2. Setup time without IT support — 1–3-person or volunteer-run teams. If the sales cycle requires a demo and a contract, your real go-live is weeks away. Form-first tools (Zeffy, Donorbox, GiveLively) publish same-day and require no technical configuration. DonorPerfect, Neon One, and Blackbaud all require onboarding time that small teams rarely have.

• 3. Unified fundraising + donor records — donor list under 5,000. If your donation form is on one platform and your CRM is on another, you'll spend hours reconciling them. Pick a tool where donations auto-write to the donor record. For lists under 5,000, Zeffy's unified system handles this out of the box.

• 4. How it scales under 5,000 donors. Watch out for the Community Music School pattern — "free" tools that start charging at the next tier. Confirm the pricing holds at 1,000, 2,500, and 5,000 contacts before you commit.

• 5. Built-in tax-receipt automation. Without a database manager, manual receipting eats your week. Automatic IRS-compliant receipts on every gift are table stakes.

4 nonprofit case studies: what actually worked

Community Music School of Santa Cruz — $47,664 raised, $2,383 saved

Community Music School of Santa Cruz moved to Zeffy after their previous donor management system eliminated free accounts. They've since raised $47,664 and saved an additional $2,383 in transaction fees that would have gone to platform overhead.

I love the ability to quickly email people who've attended any one of our past events — it's simple and the 'from' line in the customer's email is our name, so there's no confusion. I also appreciate the ability to embed the donation form or ticketing form into our website. Finally, I couldn't ask for better customer service.
— Susan Willats, Community Music School of Santa Cruz

‍

Cincinnati Song Initiative — switched from GiveLively

Cincinnati Song Initiative previously ran donations through GiveLively before moving to Zeffy for the unified donation-and-event experience that better matched how they actually work.

‍

Twin Steeples Foundation — moved off $125/month Bloomerang

Twin Steeples evaluated Bloomerang first. Their summary: "Bloomerang plans start at $125 every month." After comparing total cost of ownership against a free alternative that covered their use case, they moved to Zeffy.

‍

Sustainable Princeton — replaced a Kindful + PayPal + Eventbrite stack

Sustainable Princeton was running Kindful (now Bloomerang), PayPal, and Eventbrite — three tools, three logins, manual reconciliation. They consolidated to Zeffy to bring donations, event ticketing, and donor records into one record system.

‍

The bottom line for small nonprofits

Start free, upgrade when complexity demands it. For nonprofits under 5,000 donors with a budget closer to $0 than $500/month, Zeffy is the database that grows with you without charging per record. If and when your stewardship workflow grows into wealth screening or a populated engagement meter, Bloomerang is the honest next step. If you're a university or hospital foundation, you already know Raiser's Edge NXT is your tier.

For everyone else: don't pay $1,500+/year for software your team won't fully use this year.
