Sonic Infosystem is a website design company in Mumbai and Navi Mumbai that has designed websites for Indian businesses since 2003. We create custom, mobile-first websites for manufacturers, exporters, healthcare brands, real estate developers and service companies, designed to make your business look established and to turn visitors into enquiries.
For most buyers, your website is the first serious evaluation of your company. Procurement teams, distributors and customers judge your capability, scale and reliability within seconds. A dated or generic website quietly loses you business; a well-designed one makes you the obvious choice.

- SEO built in from day one: page structure, headings, speed and schema are planned for Google before the first pixel is drawn.
- 20+ years of experience: we have designed websites through every era of the web, and we know what keeps a site effective for years, not months.

- Discovery: we study your business, target customers and competitor websites to define what the site must achieve.
- Sitemap and wireframes: page structure and content priorities are agreed before visual design, and mapped to the keywords you need to rank for.
- Visual design: high-fidelity designs for desktop and mobile, built on a consistent design system of typography, colour and components.
- Approval: you review and approve every key page before development begins, which keeps timelines and budgets predictable.
- Development and launch: our web development team builds the site with an easy admin panel, tests it on every device and launches it with tracking in place.
Designed for speed, mobile and Google
More than half of website visits in India now come from mobile phones, so every design starts with the small screen. Our layouts use lightweight code and optimised images to load quickly and score well on Google Core Web Vitals. Clear heading structure, descriptive content and schema markup give each page the best possible start in search, and our SEO team can take it further after launch.

Website Design: common questions
How much does a website cost in Mumbai?
It depends on the number of pages, the amount of custom design and features such as catalogues, payments or multiple languages. We provide a fixed, itemised quote after a free consultation, with no hidden costs.
How long does it take to design and develop a website?
A typical corporate website takes three to six weeks from the first meeting to launch. Larger websites, e-commerce stores and custom web applications take longer, and we agree the timeline with you at the start.
Do you use ready-made templates?
No. Every website is designed from scratch around your business, content and customers. We use proven interface patterns, but the design itself is original to your brand.
Will my website be mobile-friendly and SEO-ready?
Yes. Every website is designed mobile-first, tested on phones, tablets and desktops, and built with clean code, fast loading, proper headings, meta tags and schema markup.
Can I update the website myself?
Yes. Your website comes with an easy admin panel to edit pages, add products or blog posts and update SEO details without any coding. We also provide training and support.
Do you work with clients outside Navi Mumbai?
Yes. We work with businesses across Mumbai, Thane, Pune and the rest of India, as well as overseas clients, through online meetings, phone and email.
