From a rented theme to a Next.js storefront you own.
Your backend already works — catalog, checkout, orders all flow. It's the theme that's the ceiling: load times past 3 seconds on sale days, designs Liquid can't express, SEO you can't fully control. This engagement rebuilds only the frontend — a Next.js storefront on the Shopify, Medusa.js, or Vendure backend you already run. ₹4,00,000 + GST fixed, 3–4 months, full code ownership.
One build. ₹4,00,000. The frontend, done properly.

₹1,00,000 more buys ₹2,75,000 of engagements.
This build assumes your design files are dev-ready and your store is already in shape. If either isn't true, the enterprise bundle is usually the cheaper path — same headless build, three engagements folded in.

vs ₹4,00,000 standalone
- Store development — catalog, payments, shipping, GST setup₹50,000 standalone
- UI/UX design — the storefront drawn phone-first in Figma₹1,50,000 standalone
- CRO pass — 344 checks implemented on staging before launch₹75,000 standalone
Three engagements, ≈₹2,75,000 bought separately — folded in for the ₹1,00,000 difference. One team, one scope, one timeline.
See the ₹5,00,000 bundleThe engine stays. The front gets rebuilt.
Six things the ₹4,00,000 ships — on the Shopify, Medusa.js, or Vendure backend you already operate.
A Next.js frontend you own
Your storefront rebuilt as a Next.js app — server-rendered and statically generated, deployed on Vercel's edge or your own India-region server. You control the UI, the SEO, and the render down to the component.
On the backend you already run
Shopify's Storefront API, or your existing Medusa.js / Vendure instance. We integrate with the engine you operate today — no replatforming, no backend migration.
Core Web Vitals, controlled
Static and server-rendered pages, image and bundle discipline, ISR that refreshes on a webhook instead of a timer. Google's bar for a good LCP is 2.5 seconds — we build to beat it.
Built for peak traffic
Diwali, EOSS, a flash-sale spike — static and edge-served pages absorb the surge, so the ads you run on a sale day land on a page that loads, not a spinner.
SEO carried over, not gambled
301 redirects mapped for every legacy URL, metadata and schema emitted from the new storefront — you keep the search equity the old store earned.
Full ownership, no lock-in
Complete source, the deployment project, and documentation handed over. Swap the frontend or move the backend later without rebuilding everything.
Fit check to cutover — 3–4 months.

When you should not buy this.
Below roughly ₹50L/month in revenue, don't. A good theme still does the job at that scale, and the same budget spent on the ₹50,000 store build plus the ₹75,000 CRO pass returns more than a headless rebuild.
And if your design files aren't dev-ready or the store itself still needs work, the standalone build is the wrong door — buying design and store setup separately erases most of the ₹1,00,000 you saved. Take the bundle instead; it exists for exactly that case.
How the 3–4 months run — milestone by milestone.
Complete transparency. Six milestones from fit check to handover, each with what we ship and what you receive.
- Milestone 01Week 1
Fit Check — Honestly
A 30-minute call to confirm a headless frontend is right for you — before any money moves.
- Under roughly ₹50L/month, we'll usually tell you to stay on a good theme — the same budget on CRO and acquisition returns more at that scale.
- We check the two standalone prerequisites on the call: dev-ready design files, and a store/backend that's already in shape. Missing either usually makes the bundle the cheaper path — we'll say so.
- If the fit is right, you get access to our client portal at portal.growwwtech.com for feedback, approvals, and progress tracking.
You'll receive
- Straight fit verdict on the call
- Client portal access
- Current-store audit notes
- Milestone 02Weeks 2–3
Architecture + Scope
We map the storefront, the API surface, and the render strategy against the backend you already run — then the scope is fixed in writing.
- Per-page render strategy: static, server-rendered, or ISR — decided by how often the content changes, not by default.
- Your backend stays where it is: Shopify's Storefront API, or the Medusa.js / Vendure instance you already operate. We integrate; we don't rebuild the engine.
- Checkout follows your backend — Shopify's hosted checkout stays on Shopify headless; on Medusa.js or Vendure your existing payment wiring carries over.
You'll receive
- Architecture map
- Fixed written scope
- Render strategy per page type
- Milestone 03Months 1–3
Build in Sprints
The Next.js storefront built from your design files — 2-week sprints, weekly demos on a staging URL.
- You watch the store take shape on staging every week — no three-month silence, no big reveal.
- Built from your dev-ready design files as drawn. If the files aren't ready, the UI/UX design engagement (₹1,50,000) or the bundle covers it.
- Storefront talks to the backend over GraphQL; either side can be swapped later without rebuilding the other.
You'll receive
- Weekly staging demos
- Next.js storefront (SSR / static / ISR)
- Backend integration over the storefront API
- Milestone 04Final weeks
Performance + SEO Pass
Core Web Vitals green, metadata and schema wired, and every old URL mapped so you keep your search equity through the cutover.
- Google's bar for a good LCP is 2.5 seconds — we build to beat it. Speed comes from how it's built, not the architecture alone.
- 301 redirects mapped for every legacy URL; metadata and structured data emitted from the storefront you own.
You'll receive
- Core Web Vitals report
- Redirect map + schema wiring
- Milestone 05Month 3–4
Launch + Handover
Cut over with no downtime — rewiring the building with the lights on. Then everything is handed over.
- Zero-downtime cutover, monitored through the first sale days.
- Complete source code, the deployment project, and documentation — full ownership, no lock-in, no AMC.
You'll receive
- Zero-downtime launch
- Full code + deployment handover
- Documentation written for your team
- Milestone 06
Out-of-Scope Work Policy
Any request beyond the fixed written scope is out-of-scope work — handled transparently, never silently billed.
- Store development, design, CRO, backend changes, and ERP/B2B integrations are separate engagements — the bundle exists precisely to price the common ones together.
- Smaller extras are tracked in the Growww Tech client portal and billed only with your approval.
You'll receive
- Transparent time tracking via portal
- Prior intimation before any additional billing
What we need from you. What we don't do.
No surprises post-kickoff. Here is the assumption boundary on both sides — and most of the right column is exactly what the bundle folds in.
What we need from you
- Dev-ready design files (Figma) — no files yet? The ₹1,50,000 UI/UX engagement or the bundle covers it
- A store/backend already in shape — catalog, pricing, and checkout working today
- API access to your backend (Storefront API token, or your Medusa.js / Vendure instance)
- Access to analytics and Search Console for the audit and redirect map
- A decision-maker on the weekly demo call
- Consolidated feedback within 3 working days per review round
What's not included
- Store development — catalog, payments, shipping, GST setup (₹50,000 standalone, or folded into the bundle)
- UI/UX design — we build from your files; drawing them is the ₹1,50,000 engagement (or the bundle)
- CRO — the 344-point pass is ₹75,000 standalone (or folded into the bundle)
- Backend setup or migration — moving platforms is bundle/enterprise scope
- ERP integration and complex B2B logic — scoped and priced separately
- Copywriting, product photography, and video
- Backend hosting and platform fees — servers, Shopify subscription, gateway charges are billed to you directly
