Headless Commerce Development
Headless Commerce Storefronts
on Next.js - for Any Backend
We build the storefront. You keep - or pick - the backend. Shopify, BigCommerce, Adobe Commerce, commercetools, Medusa, or your own GraphQL. Frontend-led headless without a full replatform.

The Storefront Layer, Decoupled
Most SaaS commerce platforms ship a backend you love and a storefront you tolerate. Headless commerce splits the two. We build a fast, modern Next.js storefront - branded, accessible, AI-search-ready, edge-rendered - and plug it into the commerce engine you already run.
Keep Shopify Plus, BigCommerce, or Adobe Commerce as the backend. Or pick a composable engine like commercetools or Medusa.js. Either way, the storefront is yours: every byte, every component, every analytics event, every schema entry.
If you're considering a full backend rebuild too, jump to custom platforms. If you need to replatform first, see platform migrations.
Headless commerce development, step by step
Headless commerce code that is tested before it goes live
Every Headless commerce change is written, built and checked before it reaches your store. Speed and accessibility checks run on each release, and nothing ships until they pass, so the live store stays fast and stable while it grows.
- ›Headless commerce themes, apps and integrations built by specialists
- ›Speed and accessibility checked on every release
- ›Launched to your live store only once the checks pass
When headless is the right call
The Six Signals
- ›SaaS theme limits are throttling conversion.Theme extensibility caps, app conflicts, checkout UX you can't touch - your platform's frontend is now a measurable drag on conversion, AOV, or content velocity.
- ›Core Web Vitals are bleeding revenue.Monolithic SaaS frontends carry render-blocking apps and bloated CSS. Sub-1.5s LCP at the 75th percentile is achievable on Next.js - and Google rewards it.
- ›Multi-brand, multi-region, B2B in one cart.Tiered pricing, account-gated catalogs, region-specific tax/duty, and consumer checkout under one storefront - composable on top of one commerce engine.
- ›AI-search readiness is non-negotiable.ChatGPT, Perplexity, and Gemini cite pages with clean SSR, full schema graphs, and extractable copy. Heavy-JS SaaS themes hide your catalog from the crawlers that matter now.
- ›Developer velocity is gated by theme deploys.Every change blocks on a platform-managed release. Headless = your team ships to Vercel preview URLs in minutes, not days.
- ›You're not ready to replatform - but you need a modern UX.Keep the backend that's working. Replace the storefront that isn't. Full replatform later, after you've proven the storefront.
When it isn't
When to Skip Headless
- ×You're under $2M GMV with a simple catalog.A polished SaaS theme will out-ship headless on TCO, speed-to-market, and team velocity. The operational overhead of a decoupled storefront rarely pays back at that scale.
- ×You don't have product engineering capacity.Headless storefronts need owners. If there's no internal team - or budgeted partner retainer - to steward the build, the SaaS theme is the safer bet.
- ×Your moat is merchandising, not UX.If the brand wins on assortment, pricing, or community, a faster SaaS launch beats a slower headless rebuild. Every quarter the rebuild delays is revenue lost.
- ×Your roadmap is uncertain.Headless amplifies decisions - good and bad. Lock product strategy first. Build the storefront around the proven model.
Not the right fit? Start with our SaaS platform hub- we'll match you to the right backend before you spend a dollar on headless.
What ships in the storefront
The Frontend We Ship
Every headless build ships on the Next.js App Router with React Server Components, ISR + edge caching, and a typed design system. We treat performance as a feature, not a launch-night scramble - Lighthouse and Core Web Vitals are budgeted from the kickoff brief, monitored in production, and tied to revenue dashboards.
The codebase is yours from day one. Vercel deploy, your repo, your CI/CD, your environment variables. We document component boundaries so a successor team - yours or another agency - can pick up the build without a knowledge handoff tax.
Deep links into how each layer ships: design system + UX, development & engineering, conversion optimization.
Content that ships with it
Editors Ship Without a Redeploy
The storefront ships with WorkspaceCMS- our proprietary platform for editorial content, lead capture, per-page SEO overrides, and schema management. Non-technical editors update copy, swap hero imagery, and tune meta tags from a clean admin. No PR. No deploy. No ticket queue.
Schema, alt-tags, redirects, and structured data are first-class citizens. The same control panel drives our AI SEO work- your storefront is built to be cited by ChatGPT, Perplexity, and Gemini from launch day, not retrofitted after the fact.
Deep links: eCommerce SEO, answer-engine optimization, agentic-commerce readiness.

How we ship
Discovery to Launch in 10–16 Weeks
Six phases. Vercel preview URLs from week one. Revenue keeps running on the existing stack until parity is proven.
Discovery & architecture
Audit the existing storefront, map data contracts, and lock the integration approach for your backend. Performance budget set, schema graph drafted, success metrics agreed before a line of code.
Design system
Token-first design system in Figma + code. Components built for accessibility (WCAG 2.2 AA) and Core Web Vitals from the first prototype.
Build
Next.js App Router. Server components first. ISR + edge caching where it matters. Vercel preview URLs for every PR so stakeholders see progress weekly.
QA & performance
Lighthouse and CWV gates in CI. Cross-browser, cross-device. Real-user monitoring wired before the cutover, not after.
Launch
URL mapping, 301 redirects, schema parity, AI-crawler accessibility (llms.txt, GPTBot, ClaudeBot), analytics baselines. Quiet, boring launches are good launches.
Iterate
Post-launch retainer: CRO, AI SEO, content velocity, dependency upgrades, and the swap-in of new backends or services as the roadmap evolves.
Frequently asked
What Buyers Ask First
What is headless commerce development?
Building a decoupled storefront (typically Next.js) that talks to a commerce backend via API instead of using the backend's bundled theme layer. The storefront controls UX, performance, and SEO independently of the commerce engine.
What's the difference between headless commerce and composable commerce?
Headless decouples the frontend only. Composable (MACH) decouples every layer - frontend, cart, search, CMS, payments - into best-of-breed services. Headless is a step; composable is the full architecture.
Do I need to replatform to go headless?
No. You can keep Shopify, BigCommerce, or Adobe Commerce as the backend and only swap the storefront. That's the typical 1Digital engagement on this page.
How long does a headless commerce build take?
A production Next.js storefront on an existing backend typically takes 10–16 weeks. Full composable rebuilds with a new backend run 4–9 months.
What backends can a Next.js storefront connect to?
BigCommerce, Shopify (Storefront API / Hydrogen), Adobe Commerce (Magento), commercetools, Medusa.js, Saleor, Swell, and custom GraphQL/REST APIs.
Is headless commerce better for SEO?
Yes when done right - full SSR/ISR control, faster Core Web Vitals, and structured-data ownership. Done poorly (heavy client-side rendering, no SSR) it can be worse. Done by an SEO-led agency, the gains are large. The full playbook lives at headless commerce SEO.
What does headless commerce cost?
Every headless build is custom-scoped, so we don't publish fixed price bands. Cost is driven by integration scope (which backend, which ERP / OMS / PIM, B2B vs. consumer, multi-region), the depth of the design system, and whether the engagement is frontend-only or includes a composable backend rebuild. Tell us about the project and a senior engineer replies within one business day with a scoped estimate.
Who should NOT go headless?
Stores under ~$2M GMV with simple catalog needs and no custom UX pain - the operational overhead rarely pays back. Honest answer matters more than the sale.
