Sonic Infosystem is an ecommerce website development company in Mumbai and Navi Mumbai that builds online stores for retailers, D2C brands, manufacturers and B2B suppliers. We develop on Shopify, WooCommerce and custom Laravel platforms, choosing the one that fits your catalogue, budget and growth plans.
An online store succeeds or fails on details: how quickly products can be found, how much shoppers trust the store, how smooth the checkout is and how easily your team can manage orders. We build stores that get those details right.
E-commerce development services
Shopify store development
Store setup, custom themes, apps and integrations for fast-growing D2C brands. See our dedicated Shopify development service.

Payments, shipping and GST
Razorpay, PayU, Cashfree, Stripe and other gateways, cash on delivery, courier integrations, GST-compliant invoices and tax rules configured correctly from day one.
Product content and imagery
Clean product photography, product image editing, 3D product renders and descriptions that help shoppers decide.
Shopify, WooCommerce or custom: how we choose
Platform choice affects your running costs and how easily the store can grow, so we decide it with you rather than defaulting to one option.
- Shopify: best when you want a managed platform, quick launch and minimal technical upkeep.
- WooCommerce: best when you already use WordPress, want full ownership of hosting and data, or need content and shop on one site.
- Custom Laravel: best for B2B catalogues with thousands of items, customer-specific pricing, request-a-quote flows or deep ERP links, such as pharma and industrial suppliers.
Built to sell and to rank
- Fast, mobile-first storefronts: most Indian shoppers buy on their phones, so every store is designed and tested mobile-first.
- Conversion-focused checkout: fewer steps, trust signals, multiple payment options and abandoned-cart recovery.
- E-commerce SEO: category and product page structure, schema, site speed and content that help your products appear on Google.
- Marketplace growth: optional Amazon, IndiaMART and marketplace listings to reach more buyers.

E-commerce development in Mumbai and Navi Mumbai
We are based in Navi Mumbai and build stores for sellers in Kharghar, Panvel, Belapur and Thane, and across Mumbai in Andheri, Goregaon and Lower Parel, as well as brands shipping across India and overseas. Local sellers often want same-day or area-based delivery rules and COD limits by pincode, which we configure as part of the build. If you sell to trade buyers, we can also add GST number capture at checkout, minimum order quantities and bulk enquiry forms that go straight to your sales team on email or WhatsApp.

E-commerce Development: common questions
How much does an e-commerce website cost in India?
It depends on the platform, product count, custom features, integrations and design. We give a fixed, itemised quote after a free consultation and recommend the most cost-effective option.
Which is better for my store: Shopify or WooCommerce?
Shopify suits brands that want a fully managed platform and fast setup. WooCommerce offers more flexibility and control. Complex B2B catalogues may need a custom platform. We recommend based on your needs.

Yes. We integrate Razorpay, PayU, Cashfree and other gateways, and configure cash on delivery, shipping partners and GST invoices.
Can I manage products and orders myself?
Yes. Every store includes an easy dashboard to add products, update prices and stock, and manage orders, with training for your team.
Will my online store be SEO-friendly?
Yes. We build SEO-friendly category and product structures, fast pages and schema markup, and offer ongoing e-commerce SEO.
Do you also help sell on Amazon and marketplaces?
Yes. We create and optimise listings on Amazon, Flipkart, IndiaMART and other marketplaces alongside your own store.
