Case Study · Custom Donation Portal · 2026

A custom donation form that saves 2.9% on every transaction.

Travel For Purpose needed a donation flow that didn't bleed money to third-party platform fees. We built it from scratch — Stripe integration, custom checkout, fully tested, deployed in production. Every dollar that would've gone to platform fees now goes to the cause.

What we built

Full-stack, end-to-end, production-ready.

01

Stripe payment integration

Direct connection to Stripe — secure, PCI-compliant, supports cards and Apple/Google Pay. No third-party donation platform in between.

02

Custom-coded checkout

Brand-aligned form built in clean HTML/CSS/JS. Designed to convert — no friction, no distracting platform branding.

03

End-to-end testing

Full test passes on every flow — success, declined card, network errors, mobile, desktop. Shipped only when every path was solid.

04

Netlify deployment + functions

Hosted free on Netlify with serverless functions handling the Stripe webhook. Scales to thousands of donations a month with zero infrastructure cost.

Why custom matters

Every dollar in fees is a dollar not in the mission.

Platform fees saved
2.9%
On every transaction, forever.

Most donation platforms — Donorbox, Givebutter, Classy — layer their own 2.9% platform fee on top of payment processing. For a nonprofit moving real volume, that's thousands of dollars a year that never reach the cause.

Going direct to Stripe with a custom-built form cuts that layer out completely. Same secure checkout. Same trusted payment processor. None of the middle-platform overhead.

It's not just about saving money. It's about respect for every donor's intent — when someone gives $100, all $100 should go to the work.

The flow — from form to Stripe in one click.

Custom forms, checkouts, payment flows — we build them.

Donation portals are just the start. If you have a payment, signup, intake, or checkout flow that's being held hostage by a third-party platform, we can build you a custom version — branded, conversion-focused, and yours forever.
