Overview

Used-car showrooms in Kerala have no shared marketplace and no simple tool for running their stock, leads and accounts. Buyers struggle to find trustworthy cars from approved dealers, and private sellers struggle to sell safely.

Prevauto is three apps on one platform. Buyers search approved showrooms’ cars, chat with the showroom and book test drives on a fast, SEO-friendly website. Owners can sell their car to a showroom at a price agreed in the app, or park it and let the showroom sell it. Each showroom runs its stock, leads, chats, sales and money in its own panel, and the platform team approves showrooms and keeps the marketplace safe from an admin console with a full paper trail.

Highlights

  • Three apps on one multi-tenant platform: website, showroom panel and admin console
  • Safe in-app chat between buyers and showrooms
  • Car owners can sell to a showroom or park & sell
  • Website and panel both install on Android and iPhone
