UPI Payment Gateway & Course Application Platform

A course-application platform with built-in UPI QR payments, unifying applications and payment collection.

The Problem

Understanding the business challenge.

Course providers in India need a frictionless way to accept UPI payments alongside applications, without a heavyweight payment gateway integration.

Manually cross-referencing payment confirmations against applications is error-prone.

International applicants need phone number validation that domestic-only forms don't support.
