Overview
Rentyx is a heavy-machinery and construction equipment rental platform in Slovakia. Built a modern, catalog-driven web application organized around four core machinery categories, replacing cumbersome phone inquiries with a guided, mobile-optimized quote-request engine backed by Sanity CMS.
The Problem
Contractors working on active construction sites need to verify equipment availability and pricing quickly. Traditional rental firms relied on static PDFs and manual phone calls, while standard e-commerce checkouts were incompatible with complex deposit rules and rental agreements.
- ▸Contractors on job sites struggled to navigate PDF brochures on mobile screens.
- ▸Phone-only inquiry workflows led to lost leads and slow quote turnaround.
- ▸Non-technical staff had no straightforward way to update machine availability.
The Solution
Architected a mobile-first Next.js catalog site optimized for site managers. Instead of an awkward cart, the application features a streamlined quote builder where users select machinery, enter job dates, and submit specifications. Integrated Sanity CMS allows the local team to update specs and pricing in real time.
- ✓Mobile-first responsive interface with fast search and equipment filtering.
- ✓Structured quote inquiry engine routing requests directly to dispatchers.
- ✓Localized CMS powering multi-language machinery specifications.
- ✓Static generation with revalidation for instant page loads on cellular networks.
