The first challenge, we faced was meeting the high-standards for UI/UX for Razorpay customers to make sure our solution was easy and intuitive for businesses to understand. Further, we faced challenges on creating a seamless flow for money transfer between the current account of business and Liquid mutual funds using Subscriptions API as we need to debit variable amount along with variable time durations. The biggest technical challenge was to create the front and backend infrastructure for the dashboard that was smooth and glitch-free. The main issue being creating error-free business login in the backend as it involved dealing with multiple real-time transactions as well as reconciliation at multiple steps. We accomplished this using AWS for hosting, as well as MERN stack for front and back-end infrastructure.
