Brand equity and sub-second infrastructure from one team: editorial narrative, high-ROAS ads, and Next.js code your company owns.
Panarch Digital is one studio for D2C brands: brand positioning, Meta & Google performance ads, and headless Next.js storefronts you own outright. Our own site, panarchdigital.com, measures 0.47s P75 LCP on mobile, and that is the performance budget every storefront we ship is engineered against.

Revenue-leak calculator
Two inputs, one published coefficient. Take your LCP from PageSpeed Insights (the field-data figure, if your site has one).
Illustrative monthly leak
25.2% of monthly revenue · 3 × 0.1s steps counted (your gap is 0.9s; capped at 3)
Illustrative estimate — based on Deloitte/55 2020 retail data, not a guarantee. Milliseconds Make Millions (opens in a new tab)
steps = min(max(0, 3.4s − 2.5s) ÷ 0.1s, 3) = 3
leak = ₹25,00,000 × 8.4% × 3 = ₹6,30,000 / month
8.4% is the retail conversion lift Deloitte and 55 measured per 0.1s of mobile speed improvement (2020). Time under Google's 2.5s “good” LCP threshold (opens in a new tab) is not counted, and because the study measured 0.1s changes we stop extrapolating at 3 steps. Revenue is assumed to move one-for-one with conversion rate (same traffic, same order value).
Capabilities
Four units run by one team. Brand tokens become the storefront's design system, ad creative is cut from the same identity, and every page ships with the schema Google and AI answer engines read.
Visual density, editorial precision, and positioning narrative that commands pricing power.

High-ROAS Meta & Google ad funnels, conversion video, and systematic creative testing.

Decoupled Next.js infrastructure. Sub-second mobile loads, 100% owned code, zero platform rent.

AI-native search visibility that captures intent across Google, Perplexity, and ChatGPT.

Sprint methodology // 4 phases
One team runs brand, ads, content and code in the same sprint, so the identity, the ad creative and the storefront ship against one plan.
We review the whole growth engine: brand positioning, ad account unit economics, checkout friction and tech debt.
Brand narrative, ad creative and the Next.js storefront are built in the same sprint, against one plan.
Meta Conversions API, server-side attribution, security hardening and checkout conversion work.
Scale Meta and Google spend against server-side attribution, publish on a fixed cadence, and hold the storefront to its performance budget.
PORTFOLIO // CASE STUDIES
3 live client platforms and 3 studio prototypes. Each case study names the framework, data model and trade-offs as they exist in the repository, and prototypes are labelled as prototypes.
An atelier storefront for single-bolt natural textiles: a Postgres roll allocator under row locks, 0.5m cuts in 0.1m steps, a swatch credit ledger and a Gemini 2.5 Flash concierge.

We brought a pan-India fabric wholesaler online with a bespoke platform: an editorial D2C storefront, a B2B wholesale channel with enforced MOQs, and a full owner CMS backed by atomic Postgres row locks.

We architected an institutional platform for a 4-wing public trust, running a 40-seat student scholar cohort, 34 rescued dogs across 4 shelter homes, and a WhatsApp emergency dispatch grid.

A four-day studio prototype: an industrial brutalist storefront with high-density off-grid boundaries, a Supabase Auth gateway, a role-gated Admin Terminal and Razorpay-ready checkout on Cloudflare Workers.

A Vite + React boutique concept balancing generous whitespace with a metal and engraving configurator, live USD / EUR / GBP pricing and a concierge checkout for six-figure pieces.

A stark, structural flagship concept in obsidian, gallery white and brushed gold, with GSAP-pinned editorial galleries and Lenis momentum scroll.

What a D2C brand pays and owns on Shopify Plus versus a custom Next.js storefront.
| Dimension | Rented SaaS (Shopify Plus) | Owned stack (Panarch Digital) |
|---|---|---|
| Source-code ownership | None: storefront is coupled to Liquid templates and Shopify's database | 100%: a standalone Next.js repository in your GitHub |
| Platform licence | From $2,300/mo on a 3-year term ($2,500 on 1-year); Shopify India lists ₹1,75,000/mo | $0 recurring licence |
| Third-party gateway fee | 0.2% on every order paid through Razorpay, Cashfree or PayU, on top of the gateway's own rate | None: direct settlement with Razorpay or Stripe at the gateway's own rate |
| Hosting / infrastructure | Bundled into the licence; shared multi-tenant platform | Vercel Pro: $20/mo per deploying seat plus usage, in your own account |
| Performance | Depends on theme and installed apps; no published speed guarantee | 100/100 Mobile Lab / 0.47s P75 LCP / 87ms TTFBPanarch benchmark: panarchdigital.com, P75 field data, 9 Jul 2026 |
| Platform lock-in | High: proprietary Liquid templates and app ecosystem | None: open Next.js and React |
| Maintenance talent pool | Shopify and Liquid specialists | Any React / TypeScript engineer |
Latency has a measured price: a 100-millisecond delay in page load cut conversion rates by up to 7% in Akamai's State of Online Retail Performance report (Spring 2017) (opens in a new tab).

Objections // Answered
A headless architecture separates the storefront (frontend) from the commerce backend through APIs. Panarch Digital builds the frontend in Next.js and renders it at the edge. Our own site, panarchdigital.com, measures 100/100 Mobile Lab, 0.47s P75 Largest Contentful Paint and 87ms TTFB, well inside Google’s 2.5s “good” LCP threshold, and that is the performance budget every storefront we ship is engineered against.
Shopify renders storefronts through its proprietary Liquid templating language and extends them through paid apps; Webflow is similarly hosted and closed. Both decide what your checkout, data model and page weight can be. Panarch Digital writes a standalone Next.js and Supabase application around your catalogue, so every page, script and checkout step is code you can change, profile and keep.
Your site keeps running. The source code lives in your GitHub repository and the site is deployed to your own Vercel account, so no part of it depends on Panarch Digital’s accounts. Because the architecture is standard Next.js rather than a proprietary framework, any qualified developer can maintain or extend it independently.
A focused headless migration from Shopify typically runs 8–14 weeks: the 8–12 week build sprint (data modelling, component architecture, payment integration, performance tuning) plus catalogue migration and SEO preservation. Larger or enterprise migrations run 3–6 months.
No. Vercel is usage-based infrastructure, compute and CDN, not a software licence with revenue sharing. Vercel Pro is $20 per month per deploying seat plus usage, and it scales with traffic. Shopify Plus starts at $2,300 per month on a 3-year term, plus a 0.2% fee on orders paid through third-party gateways (prices as of October 2026). An owned stack carries no platform licence fee.
We run a dual-stack cutover. Your current store stays live while the new Next.js storefront is built and tested against it: redirects, analytics and checkout are verified before any traffic moves. The switch is a routing change at the edge, and rolling back is the same change in reverse, so an issue found after launch is reversed in one step instead of fixed under live traffic.
Because the application is built on un-ejected, standard Next.js, any mid-to-senior React developer can maintain it — you are never locked into an agency retainer. If you prefer, Panarch Digital offers ongoing service level agreements (SLAs) for technical oversight and continuous optimisation.
