How to Build a Fundraising Platform App with Bubble

Building a fundraising platform means solving for campaign pages, donor authentication, real-time progress tracking, and Stripe payment flows, all at the same time, all in one app.

Bubble handles every layer of that stack natively, which is why teams building custom fundraising platforms choose it over stitching together GoFundMe embeds with email tools and payment links. You get a real product, not a workaround.

Key Takeaways

• Bubble is a strong fit: Fundraising platforms need campaign pages, payment processing, and donor dashboards, all achievable in Bubble without a custom backend.
• Five core data types: Campaign, Donation, Donor, Update, and CampaignTeamMember are the foundation of the data model.
• Stripe is the payment layer: Stripe handles one-time donations, recurring gifts, and marketplace fee splits if the platform takes a percentage.
• Public and private data coexist: Campaign pages are public, but donor data and financial records require strict privacy rules at the data type level.
• MVP timeline: A functional fundraising platform takes 6–10 weeks; a full platform with team fundraising and recurring gifts takes 12–18 weeks.
• Cost range: Expect $18,000–$50,000 depending on feature scope.

What Is a Fundraising Platform App — and Why Build It with Bubble?

A fundraising platform app lets organizations or individuals create public campaign pages, accept donations, and track progress toward a financial goal. Think GoFundMe or Classy, but built specifically for your organization's needs and branding.

The two main reasons to build custom instead of using an existing platform are cost and control. Classy charges 3–5% of every donation. GoFundMe charges similar rates. Over a $500,000 fundraising year, that is $15,000–$25,000 in platform fees alone.

• Campaign page control: Custom Bubble pages let you design campaign layouts, embed video, and match branding exactly, which off-the-shelf platforms restrict or charge extra for.
• Donor data ownership: When donations go through GoFundMe, you do not own the donor data. A custom Bubble app stores every donor record in your own database.
• Flexible campaign logic: Nonprofit annual campaigns, peer-to-peer team fundraising, and emergency appeals each have different rules. Custom Bubble workflows handle any campaign structure.
• No platform percentage: Stripe's standard rate (2.9% + 30 cents per transaction) is the only payment fee. No additional platform cut on top.

The range of apps you can build with Bubble includes public-facing platforms with authenticated donor portals, fundraising platforms fit this profile well.

What Features Should a Fundraising Platform App Include?

A fundraising platform has three user-facing sides: the public campaign page for donors, the campaign owner dashboard for organizations, and the admin panel for platform operators. Each requires distinct functionality built on shared underlying data.

Start with the donor-facing experience and the core payment flow. Add team fundraising, updates, and admin tools in a second phase once the donation workflow is proven.

• Campaign creation: Title, description, goal amount, featured image, end date, and campaign owner User assignment with draft and publish states.
• Public campaign page: Real-time progress bar, total raised counter, recent donor list, campaign updates feed, and a donation button visible to all visitors without login.
• Donation flow: One-time and recurring donation options, custom amount input, Stripe-powered payment processing with success and failure state handling.
• Donor accounts: Optional registration allowing donors to view giving history and manage recurring gift cancellations without contacting the organization.
• Team fundraising: Sub-campaign pages linked to a parent campaign with a leaderboard showing individual fundraiser progress toward personal goals.
• Admin dashboard: View all campaigns and donations, export donor data to CSV, process refunds through the Stripe API, and manage campaign owner accounts.

Team fundraising is the highest-complexity feature on this list because it requires a parent-child campaign relationship and a leaderboard that recalculates as donations arrive. Build it in phase two, after the core donation flow is live.

How Do You Structure the Database for a Fundraising Platform App in Bubble?

The database requires five data types. Campaign and Donation are the core of the entire platform. Every other feature, the progress bar, the donor list, the team leaderboard, the tax receipts, is a query built on top of these two data types.

Get the Campaign-to-Donation relationship right first. The raised_amount field on Campaign updates via a backend workflow on every new Donation. Do not calculate it dynamically on page load, that approach slows down pages as donation counts grow.

• Campaign data type: Fields for title, description, goal amount, raised amount (updated by workflow), owner User, start and end dates, status option set (Draft, Active, Ended, Goal Reached), featured image, public boolean, and optional parent Campaign field for team fundraising sub-pages.
• Donation data type: Fields for linked Campaign, linked Donor, amount, donation date, Stripe payment intent ID, type option set (One-Time, Recurring), anonymous boolean, and optional message text displayed on the public donor list.
• Donor data type: Fields for name, email, linked User if registered, total giving amount (updated by workflow on each donation), and a list of linked Donations for giving history display.
• Update data type: Fields for linked Campaign, posted by User, title, body text, optional image, and published date for the campaign updates feed.
• CampaignTeamMember data type: Fields for linked parent Campaign, linked User, personal fundraising goal, personal raised amount (updated when donations are attributed to this fundraiser), page title, and personal description.

Option sets to configure: Campaign Status (Draft, Active, Ended, Goal Reached), Donation Type (One-Time, Recurring).

The CampaignTeamMember personal raised amount updates when a donor selects a specific team fundraiser at checkout. Add a linked_team_member field to the Donation data type to enable that attribution query.

How Do You Build the Core Workflows for a Fundraising Platform App in Bubble?

Six workflows power the donation process and campaign lifecycle. All six should be backend API workflows rather than client-side button workflows. Client-side workflows can fire twice if a user double-clicks, and a payment workflow firing twice means charging a donor twice.

Test every payment workflow against Stripe's sandbox mode before activating a live key. Stripe provides test card numbers and a webhook simulator in the developer dashboard for exactly this purpose.

• Donation submitted: Stripe payment intent created, on payment success the webhook fires and triggers a backend workflow, Donation record created, Campaign raised_amount incremented, thank-you email sent via SendGrid with donation amount and campaign name.
• Campaign published: Campaign owner clicks Publish, status updates from Draft to Active, public boolean set to True, campaign page becomes accessible to all visitors without login.
• Goal reached: Scheduled backend workflow runs hourly, queries Active campaigns where raised_amount is greater than or equal to goal_amount, updates status to Goal Reached, sends celebration notification to campaign owner.
• Recurring donation: Stripe subscription created on checkout, Stripe webhook fires on each successful recurring charge, backend workflow creates a new Donation record, increments Campaign raised_amount, and sends a receipt email to the donor.
• Campaign update posted: Campaign owner submits update form, Update record created with current timestamp, notification email sent to all donors linked to that campaign via a recursive batch email backend workflow.
• Campaign ended: Scheduled backend workflow runs daily, queries Active campaigns where end_date is before today, updates status to Ended, sends campaign summary email to owner with total raised and total donor count.

The notification email to all donors requires a recursive backend workflow for large campaigns. Loop through Donation records in batches of 50, sending one SendGrid email per unique donor per iteration, using a list offset parameter to advance through the list.

What Security and Data Requirements Apply to a Fundraising Platform App?

A fundraising platform contains two categories of data with opposite access requirements: public campaign content visible to all visitors, and private donor data and financial records that must never be publicly accessible. Both categories live in the same Bubble database, which makes privacy rule architecture critical.

The core principle: Campaign fields shown on the public page must explicitly allow guest read access via Bubble's privacy rules. Donor and Donation fields must require authentication under every condition.

• Public campaign access: Campaign records where public = True should be readable without authentication for title, raised amount, goal, description, and image fields. Financial details and owner contact information are excluded from this public read permission.
• Donor privacy rules: Donors can only read their own Donation records. Campaign owners see aggregate totals for their campaign but cannot access individual donor email addresses unless the donor opted into public display on the form.
• Anonymous donation handling: Donations with anonymous = True display "Anonymous" on the public donor list. The Donor record still exists privately and still receives receipt emails, the anonymous flag only affects the public name display.
• Campaign owner access: Owners can edit only their own Campaign records. Privacy rule condition: "This Campaign's owner is the current user." Admin users bypass this via a role field check.
• Stripe payment security: Stripe handles all card data. Bubble stores only Stripe payment intent IDs and customer IDs. Card numbers, CVV, and expiration dates never touch the Bubble database.
• GDPR compliance: Include a consent checkbox on the donation form. Build a donor data export workflow and a deletion workflow that removes the Donor record and all linked Donations when a deletion request is received.

Reviewing Bubble's security configuration before building any pages ensures privacy rules are set correctly from the start, not patched after a data exposure is discovered post-launch.

What Plugins and Integrations Does a Fundraising Platform App Need?

Six integrations cover the full feature scope. Four are required for the MVP. Two are phase two additions for platforms that generate tax receipts or route funds directly to campaign owners.

Keep the integration list lean. Every plugin you add is a dependency to maintain and a potential failure point during Bubble version updates.

• Stripe plugin: One-time donation processing, recurring subscription management, refund handling, and webhook configuration for payment events. The Bubble Stripe plugin handles the standard payment flow natively without custom code.
• Stripe Connect (optional): For platforms routing funds directly to campaign owners minus a platform commission. Requires onboarding each owner as a Stripe Connect account, adds 2–3 weeks of development and requires legal review of the fund flow.
• SendGrid API Connector: Transactional emails for donation thank-yous, recurring receipts, campaign update notifications, and campaign end summaries. Dynamic template variables in SendGrid pull donor name, amount, and campaign details from Bubble data fields.
• Bubble's native image uploader: Campaign featured images and update images. No additional plugin needed for standard image upload, storage, and display.
• OpenGraph meta tags: Set in Bubble's page SEO settings for each campaign page URL. Critical for fundraising platforms where campaigns are shared on social media and link preview quality affects click-through.
• PDF Conjurer or Documint: Year-end donation receipt generation. A scheduled backend workflow in January generates a tax receipt PDF for each donor with giving history in the previous year and emails it automatically.

How Long Does It Take and What Does It Cost to Build a Fundraising Platform App with Bubble?

An MVP fundraising platform with campaign creation, a working donation flow, and a campaign owner dashboard takes 6–10 weeks. Adding team fundraising, recurring donations, campaign updates, and an admin panel extends the timeline to 12–18 weeks.

The payment workflow is the primary cost driver. A simple one-time Stripe donation is a two-week piece of work. Adding recurring gifts with webhook handling plus Stripe Connect payouts for campaign owners adds another 4 weeks.

• MVP build: Campaign creation, public campaign pages, one-time Stripe donations, basic campaign owner dashboard. Timeline: 6–10 weeks. Cost: $18,000–$28,000.
• Full platform build: All MVP features plus recurring donations, team fundraising pages, campaign updates, admin panel, and year-end receipt generation. Timeline: 12–18 weeks. Cost: $32,000–$50,000.
• Bubble plan required: The Production plan ($349/month) is recommended for a public-facing platform with concurrent donors and active payment workflows. The Growth plan ($119/month) covers pre-launch testing.
• Ongoing costs: Bubble subscription ($119–$349/month), Stripe fees (2.9% + 30 cents per donation), SendGrid usage ($15–$50/month), and a PDF service subscription if using Documint.

Working with an experienced Bubble SaaS development agency on a public-facing fundraising platform reduces risk significantly, particularly around the Stripe webhook architecture and the public vs. private data separation in Bubble's privacy rules.

Conclusion

Bubble handles fundraising platforms well because campaign pages, Stripe flows, and real-time progress tracking map cleanly onto its native capabilities. Campaign and Donation data types are the foundation everything else queries from.

Start with a six-week MVP covering campaign creation, a Stripe donation flow, and a campaign owner dashboard. Validate with real donations before adding team fundraising and recurring gifts.

Building a Fundraising Platform That Donors Trust and Organizations Can Manage

Fundraising platforms handle real money and sensitive donor data simultaneously. The Stripe webhook architecture and GDPR-compliant donor handling are where most Bubble fundraising builds go wrong.

At LowCode Agency, we build Bubble apps as a full product team - not a dev shop that hands off code. We scope the architecture, engineer the workflows, and stay involved through launch and beyond.

• Data architecture: We design your data types, option sets, and privacy rules before writing a single element on the canvas.
• Workflow engineering: We build backend workflows, scheduled jobs, and API integrations with proper logic and error handling.
• Plugin configuration: We select and configure the right Bubble plugins for your feature set without unnecessary bloat.
• Role-based access: We implement privacy rules at the database level, not just conditional UI visibility.
• Integration setup: We connect your Bubble app to Stripe, SendGrid, Twilio, and other services correctly from day one.
• Pre-launch testing: We test against real data before deployment so every workflow performs correctly under live conditions.
• Post-launch support: We stay involved after go-live to optimize as real usage data shapes the app.

We have built 350+ products for clients including Coca-Cola, American Express, Sotheby's, and Medtronic. We know exactly where Bubble builds fail and we address those problems before they surface.
