3.1.3ECOMMERCE_DEV

E-com is not a website. It is checkout, payments, shipping, GST, and COD.

Shopify Plus, WooCommerce, and headless commerce — wired for UPI, Razorpay, Cashfree, Shiprocket, Delhivery, and GST 18%. India-ready from day one, not from a plugin installed on day 30.

PLATFORMS

the_logic

Indian e-com has its own rules. Most platforms assume you are shipping to Ohio.

UPI is the dominant payment method. COD is still 35–50% of orders for most D2C brands. Shiprocket and Delhivery are the logistics stack. GST 18% must appear on every invoice. GSTIN validation at checkout matters. These are not edge cases — they are the table stakes for any Indian e-com build.

Platform selection depends on where you are. 0–200 SKUs and a team that does not want to touch code: Shopify Plus with the right app stack. 200–10,000 SKUs with custom checkout logic or subscription billing: WooCommerce with a proper architecture, not the default theme. High-traffic brand that has outgrown Shopify's theme engine: headless with Medusa.js or Saleor as the commerce layer.

We do not bolt on Razorpay after the fact. We build the payment + shipping + invoicing stack in at the start, because retrofitting it always breaks something in checkout.

How it actually runs.

STEP_01 · PLATFORM

Platform selection

Shopify Plus vs WooCommerce vs headless — decision based on SKU count, checkout complexity, and growth ambition.

$ select --sku-count=N --checkout=custom? --headless=N

STEP_02 · PAYMENTS

Payment + shipping integration

Razorpay + Cashfree + UPI + COD + Shiprocket configured and tested end-to-end before a single product goes live.

$ integrate --payments=razorpay,cashfree,upi,cod --shipping=shiprocket,delhivery

STEP_03 · STOREFRONT

Theme or headless storefront

Custom Shopify theme or Next.js headless front-end — performance budget defined, mobile-first.

$ build --mobile-first=true --lcp-target=1.4s

STEP_04 · GST

GST + invoicing setup

Tax rules, GSTIN field, invoice template, and automatic email on every order — compliant on day one.

$ setup --gst=18pct --invoice=auto --email=on-order

STEP_05 · CRO

Post-launch CRO loop

Heatmaps on checkout, A/B on PDPs and cart, monthly iteration on conversion. Not a one-time launch.

$ cro --tools=hotjar,vwo --cadence=monthly

case_study

D2C_FASHION

Mumbai fashion brand replatformed from Magento to Shopify Plus. Checkout conversion +31%. Engineering budget freed.

A ₹8cr/year fashion D2C was spending 40% of engineering time maintaining a Magento 2 install — patches, hosting, plugin conflicts. We replatformed to Shopify Plus with a custom theme, Razorpay + UPI, Shiprocket integration, and GST-compliant invoicing baked in. Engineering team of 3 dropped to 1 for maintenance. Checkout conversion went from 1.8% to 2.35% on a cleaner mobile flow.
