Custom Stripe Customer Portal for Fitness & Nutrition Coaching Business
Project Overview
Built a fully custom, branded customer portal, replacing Stripe's default billing portal with a tailored solution that handles complex subscription management, retention strategies, and seamless product delivery.
The Challenge
Client offers multiple subscription tiers (monthly, quarterly, annual) as well as two separate subscription-based products for a Health&Fitnessbusiness, along with one-time purchases. Stripe's native billing portal couldn't accommodate:
Multiple active subscriptions with different management rules
Targeted retention offers based on subscription type and status
On-brand customer experience aligned with their coaching philosophy
Rewards program for loyal clients
Ability to browse and purchase additional programs without leaving the portal
Technical Solution
Developed a serverless customer portal with the following architecture.
"Browse Programs" page
Frontend & Hosting
Custom-branded interface matching the brand's aesthetic
Passwordless authentication via magic links (SendGrid API)
Deployed on Netlify with GitHub integration for version control
Backend & Integrations
Stripe API for payment processing, subscription management, and customer data
Zapier workflows automating 20+ business processes, including:
New subscription → Kajabi product access provisioning based on the product and access to the respective app
New one-time purchase → Kajabi and App access, email marketing
Canceled subscription → Retention email sequences
Cancellation requests → Targeted retention offers
SendGrid API for transactional emails and authentication
Email verification and magic link sending trigger
Key Features
✓ Dashboard - At-a-glance view of active subscriptions, next billing date, and quick actions
✓ My Purchases - Consolidated view of all products and subscription history
✓ Browse Programs - In-portal discovery and purchase of additional offerings
✓ Manage Subscriptions - Self-service pause, upgrade, downgrade, or cancel with retention offers
