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

Passwordless authentication via magic links (SendGrid API)
Deployed on Netlify with GitHub integration for version control

Backend & Integrations

SendGrid API for transactional emails and authentication
