The problem

Multi-party SaaS products require more complex payment architecture than a standard checkout. Connected accounts, seller onboarding, split payments, commissions, and recurring billing all need to remain synchronized with application workflows.

//What I built

  • SaaS application architecture designed around marketplace and subscription workflows.
  • Stripe Connect integration for multi-party payment processing.
  • Seller onboarding and connected account workflows.
  • Split transaction and platform commission handling.
  • Automated recurring subscription billing.
  • Payment activity integrated into the broader application experience.

//Architecture highlights

  • Application workflows control the business logic surrounding payment operations.
  • Stripe Connect provides the multi-party payment infrastructure.
  • Payment events are incorporated into the product workflow rather than treated as isolated transactions.
  • Subscription and billing workflows are structured for continued SaaS expansion.

//The AI layer

  • AI is not a core component of this project. The primary engineering focus is SaaS architecture, payments, and automated billing.

//Impact

  • Demonstrates SaaS architecture beyond basic CRUD functionality.
  • Handles multi-party payment requirements through Stripe Connect.
  • Connects recurring billing with application-level business workflows.
