E-Commerce Development in Mumbai: Frequently Asked Questions
How do your custom e-commerce websites compare to Shopify or WooCommerce?+
Shopify takes a monthly subscription plus a percentage cut of every order, while WooCommerce slows down as your product database grows. TechCognita builds custom headless React/TypeScript storefronts that load in under 1.2 seconds, incur ₹0 monthly platform rent, and give you 100% full ownership of your code and customer data.
Which Indian payment gateways do you integrate?+
We provide production-tested integrations with Razorpay, Cashfree, PayU, PhonePe Payment Gateway, and direct UPI QR rails, featuring automatic webhook verification and failure-recovery flows.
Can customers place orders or inquire directly via WhatsApp?+
Yes! We specialize in WhatsApp Catalog Checkouts. Customers can build a cart, click 'Order on WhatsApp,' and a pre-formatted message detailing product SKUs, quantities, and delivery address lands directly in your sales desk.
Can you build multi-vendor marketplaces or B2B distributor portals?+
Yes. We engineer multi-vendor marketplaces with vendor payout splits, commission tracking, inventory management, and B2B wholesale pricing tiers for distributors and manufacturers across Mumbai.
What is the typical turnaround time for an e-commerce website?+
A high-converting direct-to-consumer (D2C) storefront is delivered in 10 to 14 business days. Custom multi-vendor marketplaces and complex ERP-connected B2B portals are delivered in structured 3 to 4-week milestones with live staging demos.
