Overview
At RK Group, I built a used-phone sales operation across marketplace, warehouse, finance, and cross-border channels. We sold more than 10,000 devices on Udaan in four months with returns below 3%. The business moved from a 20% loss to an 8% profit.
The Story
The used-phone business required control over each device, payment, sale, return, and write-off. I led business development, pricing, sales operations, inventory, invoicing, warehouse coordination, and P and L management while working with a team across sales, finance, and operations.
Reconciliation became central to the work. Every device needed a clear status and location, whether it was with a customer, in the warehouse, returned, damaged, or written off. I worked through the stock and payment records at that level so we could make pricing and operating decisions from reliable information.
I opened and managed sales through Udaan, worked with Amazon India's used-phone team, and handled cross-border sales through Back Market in France. I also developed requirements and wireframes for customer and admin modules, then performed user acceptance testing. These modules covered registration, order creation, historical tracking, invoicing, dashboards, sales, stock, and payment reconciliation.
The operation sold more than 10,000 units on Udaan in four months while keeping returns below 3%. Pricing and operating changes improved profit margins by 20% and average revenue per unit by 5%. Over six months, the business moved from a 20% loss to an 8% profit and generated INR 30 lakh in profit.
