Launch a custom online store built for Indian buyers. Razorpay & UPI ready, GST-compliant, mobile-first design — delivered by a development team based right here in Howrah, Kolkata.
The Indian D2C and ecommerce market is exploding — but launching on a generic Shopify or WordPress template won't set you apart. As an ecommerce development company in Kolkata, Infinite Option builds custom online stores from the ground up: faster page loads, full control over your checkout, and features tailored to Indian buyers — Razorpay, UPI, Cash on Delivery, GST billing, and Shiprocket integration. Whether you're a Howrah-based boutique going online for the first time or a Kolkata D2C brand that's outgrown a template, we deliver a store you actually own, with no monthly platform tax and no design lock-in.
Razorpay, Paytm, PhonePe, CCAvenue, UPI, net banking, cards & Cash on Delivery — every major Indian payment method, tested in sandbox before launch.
Real-time stock tracking, low-stock alerts, automated inventory updates, and bulk product import via CSV. Manage thousands of SKUs without breaking a sweat.
Complete order lifecycle from cart to delivery — email/SMS notifications at every step, return and refund workflows, and one-click invoice generation.
Shiprocket, Delhivery, and India Post integration for automated AWB generation, label printing, pincode serviceability checks, and real-time customer tracking.
Full support for size, colour, weight, and material variants with individual pricing, stock, and SKU management. Built for fashion, jewellery & lifestyle catalogues.
Logged-in user accounts with order history, wishlist, saved addresses, return requests, and reorder buttons — built to drive repeat purchases from day one.
We map your products, target market, expected order volume, and India-specific needs — GST, COD, shipping zones — before writing a single line of code.
Custom UI/UX design for product catalogue, cart, and checkout flow — mobile-first, conversion-focused, and aligned with your brand identity.
Building the store with payment gateway integration, inventory engine, order management, and a powerful admin panel you can run yourself.
End-to-end testing of every payment method in both sandbox and live environments — Razorpay, UPI, COD, refunds, and edge cases all verified.
We help upload your initial product catalogue with optimised images, SEO-friendly descriptions, variants, and proper category structure.
Go live with a launch checklist, plus hands-on training for managing orders, inventory, products, and promotions in your admin panel.
A custom ecommerce website in Kolkata can start from ₹15,000 for a basic store with essential features, scaling to ₹40,000–₹70,000 for full-featured stores with Razorpay, GST billing, and Shiprocket integration, and ₹1,00,000+ for Enterprise multi-vendor builds. Final cost depends on product count, payment gateways, and integrations needed.
A Starter Store typically launches in 3–4 weeks, a Business Store in 5–7 weeks, and Enterprise multi-vendor projects in 8–12 weeks. We share a detailed week-by-week timeline before kickoff so you know exactly when each milestone hits.
We integrate Razorpay, Paytm, PhonePe, CCAvenue, and support UPI, net banking, credit/debit cards, and Cash on Delivery (COD). Every gateway is tested in sandbox before going live.
Custom is better if you want to avoid recurring platform fees, need unique workflows, or plan to scale beyond 10,000 products. Shopify is better for fast launches and managed infrastructure. We help you decide in the free consultation — we have no platform bias because we build on both.
