Sonic Infosystem is a website development company in Mumbai and Navi Mumbai that has built websites and web applications since 2003. We develop fast, secure and easy-to-manage websites in Laravel, PHP and WordPress for manufacturers, exporters, healthcare companies, retailers and service businesses.
A website is a business system. It has to load quickly, stay secure against constant automated attacks, integrate with the tools your team already uses and remain easy to update for years. Our web development practice is built around exactly those qualities.
Web development services we offer
Custom website development
Corporate and B2B websites developed from approved designs, with clean, standards-based code, responsive layouts and a custom admin panel so your team can manage pages, products, blog posts and SEO details without technical help.
Laravel and PHP development
For websites and portals that need custom logic, such as product configurators, dealer portals, quotation systems or customer dashboards, we use Laravel, a modern and secure PHP framework that is fast to build and easy to maintain.
WordPress development
Custom WordPress themes and plugins, performance optimisation and security hardening for businesses that prefer the WordPress ecosystem.
E-commerce and web applications
Online stores, booking systems, customer portals and internal tools. See our e-commerce website development and business automation services.
API and third-party integrations
Payment gateways, CRMs, ERPs, WhatsApp Business API, shipping providers, Google services and other platforms connected so that data flows without manual work.
Who we develop websites for
Much of our development work is for companies with detailed products and technical buyers. We have built sites and platforms for industrial automation (including Suraj Informatics and its Gativra platform), medical devices (SPG Medisafe), pharma companies with large product catalogues, leather exporters, travel operators such as Khanna Travels, and UPS and power equipment suppliers. These projects need structured product data, enquiry forms that reach the right person and pages that rank for specific searches.
