# How a Progressive Web App Development Company Boosts Sales Productivity for ERS – Caterpillar

### The Challenge

Energy Rental Solutions – Caterpillar (ERS) was using outdated native iOS and Android apps that were expensive to maintain, difficult to update, and lacked seamless integration with their ERP system. ERS needed a modern, cost-effective solution to streamline their equipment rental sales and marketing operations.

They partnered with Tevpro to build a **Progressive Web App (PWA)** that delivered real-time analytics and a mobile-friendly experience.
