Rent, Buy, or Sell: Do Everything On a Single Platform!


A Brief Introduction

Bainkum is a platform for people to rent, buy, or sell their assets. It brings all the asset categories under one roof to ensure a smooth renting/buying process. With a wide array of options available for the user, Bainkum hands them control over the price and products without the constraints of location.


Challenges That We Faced at the Start

The client had a great idea: to make an app where people can easily rent or sell different kinds of things all in one place. They wanted a company to help turn this idea into a real app. We were excited to work with them on this. Our job was to make the app easy to use, safe, and suitable for a variety of items. People could use the app to rent items for a short time or sell them.

Develop a trusted app for the community.

The client wanted a market for the community where they could easily buy, sell, or rent an item depending on their requirements. It should offer a fair price while maintaining integrity.


The app should be proficient enough to sustain its services

The app must be flexible enough to support the current services and allow expansion. Combined with a smooth UI, Bainkum’s overall use experience must be exceptional.


Genuine Sellers/Buyers

Bainkum must be secure enough to allow genuine sellers and buyers to rent, buy, or sell services. The team must develop ways to authenticate the users onboarding the app.


Our Solution

The requirements may seem simple, but including all the item categories while creating a sell, buy, and rent section for the same item posed a challenge. In response, we added key features like easy search, safe payments, a way to rate items, private chat, and voice calling. This made the app more than just a place to buy and sell things. It would become a community where people could share things in an innovative and friendly way.

  • User Authentication

    The team introduced user authentication to ensure swift onboarding after establishing genuine users. It helped it create a secure app that users can trust with their requirements.

  • One-to-One Chat

    The team used Socket.IO to create a chat window for users to enquire, negotiate, and interact about services and items on the app.

  • Voice calling using Twilio

    The team embedded a voice calling feature within the chat window using Twilio. It is a faster alternative to messaging in case the user wants to make an urgent deal.

  • Payment using Paypal

    The team introduced a secure payment medium through PayPal to ensure the platform remains safe for everyone. Paypal is a trusted platform that functions worldwide, thus inducing security and user trust.

Excellent Features that Shape Bainkum

Our developers studied market status and audience response to understand and create a one-of-a-kind solution. Each feature adds to the app's quality and creates a cohesive environment. This enables users to interact with Bainkum and exploit its capabilities freely.
