Self-serve plans, upgrades, trials and invoices with Stripe Billing, integrated end to end. A case study by Noah Fischer, Full-Stack Developer (Next.js & Supabase).

## Challenge

Quantora, a product analytics startup, invoiced every customer by hand. Upgrades required a call with sales, and failed payments were noticed weeks late.

## Solution

I integrated Stripe Billing with plans, trials, prorated upgrades, customer portal and dunning emails. Webhooks keep entitlements in sync, and finance gets a clean monthly revenue export.
