Nonprofits collect a lot through forms (donations, volunteer sign-ups, event registrations, grant and program applications), usually on a tight budget and often with a small team. When those forms connect to your CRM, every gift and contact strengthens your supporter data. When they don’t, you’re left reconciling spreadsheets instead of building relationships.
The best nonprofit form builders balance affordability with the integrations and payment tools that keep supporter data clean and fundraising moving. Below are the strongest options and where each fits, from free starting points to enterprise-grade platforms that grow with your programs.

The best nonprofit form builders
- FormAssembly: best for Salesforce-based nonprofits
FormAssembly is a capable nonprofit form builder that connects directly to Salesforce and Salesforce Nonprofit Cloud, so donations, registrations, and applications flow straight into your supporter records. Its connector writes to any standard or custom object and can update existing records, so returning donors don’t spawn duplicates. It handles secure payments through processors like Stripe, conditional logic, file uploads, and approvals, which means a single form can create or update several related records at once and keep your data clean as you grow.
Standout features
Deep Salesforce and Nonprofit Cloud integration, secure donation processing, prefill for returning supporters, and workflow and approval tools for grant and program applications. It serves organizations across the nonprofit sector and scales from a single donation page to multi-program operations.
✓  Keeps donor and supporter data connected in Salesforce, without duplicates.
✓  Secure payments plus complex, conditional forms.
✓  Scales with your programs and applications.
–   More capability than the very smallest orgs may need.
–   An investment beyond free tools.
Best for: nonprofits that run on Salesforce and want supporter data to stay clean and connected.
- Jotform: best for quick, low-cost setup
Jotform offers a nonprofit discount, thousands of templates, and simple integrations, making it easy for lean teams to launch donation and sign-up forms fast. Non-technical staff can build and edit forms without help, which matters when there’s no dedicated IT person. It’s a great value when speed and simplicity outweigh deep CRM mapping.
✓  Nonprofit discount available.
✓  Very easy to use, with many templates.
✓  Quick to launch donation and sign-up forms.
–   Integration depth trails Salesforce-native tools.
Best for: small teams that need forms live quickly.
- Formstack: best all-in-one option
Formstack provides discounted nonprofit plans and combines forms with documents and signatures, which is useful for grant paperwork, contracts, and internal approvals. Consolidating those needs with one vendor can simplify a small team’s tool stack. It connects to Salesforce through a managed package.
✓  Discounted nonprofit plans.
✓  Forms, documents, and signatures together.
✓  Salesforce integration via managed package.
–   More than forms-only teams may need.
Best for: nonprofits that also need documents and signatures.
- Cognito Forms: best value for donations
Cognito Forms offers affordable, payment-enabled forms that work well for donation pages and event registrations at small organizations. It supports recurring payments, which is handy for monthly giving programs. Enterprise and deep-CRM features are lighter, but so is the price.
✓  Affordable with payments built in.
✓  Recurring donation support.
✓  Easy to build and manage.
–   Fewer enterprise and CRM features.
Best for: small nonprofits focused on donations and registrations.
- Gravity Forms: best for WordPress
For nonprofits whose sites run on WordPress, Gravity Forms keeps form building on the platform they already manage, with add-ons for payments and CRM. It’s a cost-effective way to add donation and sign-up forms directly to your site. Integration depth depends on which add-ons you install.
✓  Tight WordPress fit.
✓  One-time, flexible licensing.
✓  Add-ons for payments and CRM.
–   Integrations depend on add-ons rather than a native connector.
Best for: WordPress-based nonprofit sites.
- Google Forms: best free starting point
Google Forms is free and simple, which makes it fine for quick internal surveys or basic sign-ups. It’s familiar to almost everyone and takes minutes to set up. The catch is that it lacks payments, real CRM integration, and branding, so it won’t carry a fundraising program.
✓  Free and familiar.
✓  Fast for simple needs.
✓  No setup or licensing cost.
–   No payments; minimal integration and branding.
Best for: quick, no-budget surveys and simple sign-ups.
How to choose the right one
Follow the data. If your donor records live in Salesforce, a tool that writes to it directly saves hours of reconciliation and prevents duplicates.
Check payment handling. For donations, secure and PCI-compliant payment support (including recurring gifts) is essential, not a nice-to-have.
Match the tool to your team. A small team may value simplicity over depth; a growing one will outgrow the simplest tools quickly.
Use nonprofit discounts. Most paid tools offer them. Factor discounted pricing into the comparison before you decide.
Frequently asked questions
What’s the best free form builder for nonprofits?
Google Forms is the simplest free option for basic surveys and sign-ups, but it lacks payments and CRM integration. Several paid tools offer nonprofit discounts that deliver far more value if you collect donations.
Can these forms accept donations?
Yes, most tools here support secure payment processing for donations, and the stronger ones sync each gift to your CRM automatically. Look for recurring payment support if you run a monthly giving program.
Do form builders integrate with Salesforce Nonprofit Cloud?
Some do directly. FormAssembly connects to Salesforce and Nonprofit Cloud, writing donations and registrations straight into supporter records across standard and custom objects.
Which tool is best for grant applications?
Tools with conditional logic, file uploads, and approval routing handle applications best. FormAssembly and Formstack both suit application intake and internal review.
Will these tools create duplicate donor records?
That depends on the tool. Basic connectors often only create new records, which leads to duplicates, while FormAssembly can look up and update existing records so a returning donor stays a single, clean record.
The bottom line
For nonprofits built on Salesforce, FormAssembly keeps every donation, registration, and application connected to supporter data without extra middleware or duplicate records. Jotform and Cognito Forms are great budget-friendly choices, Formstack adds documents and signatures, Gravity Forms fits WordPress sites, and Google Forms works for the simplest free needs. Choose based on where your data lives and how much your forms need to do.
