The Problem

Payment integration is complex. Stripe docs are 1000+ pages. You need checkout flows, subscription management, webhook handling, failed payment recovery, and invoice generation. Most founders spend 2-4 weeks on payments alone.

How SassyPack Solves It

  • Stripe Checkout integration with one-time and recurring payments
  • PayPal alternative for broader payment options
  • Webhook handlers for subscription events (created, canceled, failed)
  • Automatic invoice generation and email delivery
  • Failed payment retry logic
  • Customer portal for subscription management
