Estimate the number of businesses using Razorpay:‍

As of my knowledge cutoff in September 2021, Razorpay had about 500,000 businesses using their platform. Let's assume modest growth and say that currently, they have around 600,000 businesses.

Breakdown by type of business:‍

Razorpay serves a wide variety of businesses, ranging from startups to large enterprises. Let's categorize businesses into three tiers: small businesses (50%), medium businesses (30%), and large businesses (20%).

Estimate daily transaction volume per business tier:‍

Calculate total daily transaction volume:‍

Using these estimates, we can now calculate the total daily transaction volume processed by Razorpay
