Payments SaaS MVP

A rapid MVP build for a fintech startup looking to validate their B2B recurring payments platform with real merchant customers and secure Series A funding.


The Challenge

The startup had a compelling vision but zero code written. They needed a functional MVP in one quarter to present at a major industry conference and onboard early adopters. The platform had to handle subscription management, invoicing, payment processing, and reconciliation — all while maintaining enterprise-grade security.

The Solution

We executed a high-speed development sprint, building the core payments engine with Stripe Connect integration, a merchant dashboard, customer subscription management, automated invoicing, and a reporting suite. The architecture was designed for easy iteration post-launch.

Key Features

  • Stripe Connect integration for payment processing
  • Subscription management with multiple billing models
  • Automated invoice generation and delivery
  • Merchant dashboard with real-time analytics
  • Customer portal for payment history and management
  • Webhook-driven reconciliation engine
