Headless E-Commerce
Headless E-Commerce & High-Performance Shopware / Shopify Storefronts – Fast, durable, and transparently calculated at 140 €/h package rate.
End-to-end e-commerce development and conversion optimisation. From Headless Shopify to custom Next.js storefronts, we build focused sales machines. We systematically eliminate technical debt and optimize end-to-end data pipelines for sub-second rendering, superior conversion rates, and 100% data sovereignty. Engineered bespoke for ambitious B2B enterprises, SaaS builders, and mid-market leaders to drive verifiable enterprise value without vendor lock-in.
Is your online store leaking revenue?
Every millisecond counts. We engineer high-performance, independent E-Commerce platforms with sub-second load times that maximize checkout conversions.
Your legacy webshop is losing revenue through invisible friction points.
Most e-commerce stores fail because they use bloated, monolithic templates (like standard WordPress/WooCommerce) that take 4+ seconds to load. In e-commerce, a 1-second delay decreases conversion rates by 7%. If your shop struggles with mobile responsiveness or clunky checkouts, you are actively paying for traffic that refuses to buy.

Our Process
Architecture
Selecting the headless stack and mapping the data flow (PIM, ERP, CRM).
Engineering
Building a sub-second load time React frontend decoupled from the backend.
Conversion
Integrating trust signals, one-click checkouts, and behavioral triggers.
Scaling
Continuous A/B testing and infrastructure stress-testing.
The Frictionless Revenue Architecture
We don't just build stores; we engineer precisely optimized conversion pipelines.
Headless Decoupling
Separating frontend performance from backend logic for sub-second, app-like load times.
Checkout Minimization
Continuously pruning form fields and cognitive load to ensure the highest possible payment completion rate.
Data-Driven Upselling
Implementing intelligent, dynamic product recommendations based on real-time user behavior.
B2B Performance Marketing & CRO Checklist
Audit your acquisition funnel for critical conversion bottlenecks:
- Do you employ server-side tracking (CAPI) to eliminate data loss from browser blockers?
- Do your paid landing pages load in under 1.0 second on mobile networks?
- Are form fields strictly minimal and validated asynchronously with instant feedback?
- Are your campaigns segmented cleanly by buyer lifecycle stage?
- Do you continuously test contrarian angles and quantitative social proof?
- Are qualified CRM deal stages piped back into ad platforms for algorithm optimization?
Outdated Agency Standard vs. MyQuests Engineering
The Headless Advantage
We separate the frontend 'head' (what the user sees) from the backend 'body' (inventory, payments). Using Next.js/React, we build a lightning-fast interface that pre-generates pages. This 'Headless Commerce' approach means your site loads instantly, ranks higher on Google, and provides an app-like experience, while still utilizing robust backends like Shopify or Medusa for reliable order management.
„An online store is not a digital catalog; it is an systematic sales engine. Our job isn't to make it look 'pretty', our job is to precisely ruthlessly eliminate every single millimeter of friction between the user's intent and their credit card.“
Headless Commerce is overly complex and only viable for retail giants like Nike or Zalando.
With standardized Next.js Commerce starters and mature Storefront APIs from Shopify and Shopware, headless architectures are highly profitable and deployable in weeks for brands doing over 500k € in revenue.
FAQ
What is Headless E-Commerce and how does the decoupled architecture operate?
Headless e-commerce decouples the Next.js frontend presentation layer from the commerce backend (Shopify, Shopware, Medusa) via high-speed GraphQL and REST APIs.
Why does a Headless Next.js storefront dramatically boost conversion rates?
By delivering instant sub-second page transitions, zero layout shift, and frictionless mobile slide-out checkouts, eliminating bounce rates during high-intent purchase funnels.
Can an enterprise keep its existing Shopify Plus or Shopware 6 backend?
Yes, completely. Your product catalog, payment processing, inventory, and fulfillment remain intact in your existing backend while we build a bespoke, high-converting Next.js frontend.
How much does a Headless E-Commerce storefront cost at myquests?
Headless storefront projects start at 6,440 € (Tier I: 46h) for high-speed direct-to-consumer setups, and range to 11,760 € – 24,500 € for enterprise B2B multi-store architectures.
What is the difference between Composable Commerce and Headless Commerce?
Headless separates frontend from backend. Composable commerce goes further, selecting best-of-breed modular microservices for search (Algolia), CMS (Storyblok), and payments (Stripe).
How are custom B2B customer price tiers and live ERP stock levels synchronized?
We connect edge middleware directly to your ERP via WebSockets or cached Redis endpoints, streaming personalized account pricing in milliseconds upon user authentication.
Does Headless E-Commerce introduce any SEO indexing disadvantages?
No. With Next.js Server-Side Rendering (SSR) and dynamic Schema.org Product markup, headless storefronts achieve superior indexation and higher search rankings than traditional themes.
What is the typical delivery timeline for a Headless Storefront relaunch?
A streamlined storefront with core catalog and checkout launches in 4 to 6 weeks. Enterprise omnichannel platforms with complex ERP integrations deploy in 8 to 12 weeks.
Which checkout solutions provide the highest conversion rates for headless stores?
We utilize Shopify Checkout Extensibility, Stripe Custom Flow, or Shopware Native Checkout, guaranteeing 100% PCI-DSS compliance and one-click payment adoption (Apple Pay, PayPal).
Why do standard monolithic e-commerce themes fail on large catalogs (>50,000 SKUs)?
Monolithic themes execute heavy database queries on every page request, causing server bottlenecks, slow facet filtering, and crawl budget exhaustion by search engines.
Why do you exclusively build with Next.js, React, and Astro instead of WordPress or Typo3?
We rely uncompromisingly on modern frontend architectures. Legacy PHP monoliths introduce security vulnerabilities and slow rendering. With Next.js 15, React 19, and Astro, we deliver sub-second performance, maximum scalability, and 100% long-term investment protection.
Why do you charge 140 €/h for packages instead of the regular hourly rate of 200 €/h?
Our regular rate of 200 €/h applies to spontaneous ad-hoc consulting. Contracted packages allow us to plan engineering capacity efficiently. We pass this 30% planning advantage directly to our clients.
Do we own 100% of the intellectual property, code, and deliverables upon project completion?
Yes, completely. Upon full payment, you receive 100% full ownership of all source code, Git repositories, design files, campaign accounts, and data. There are zero licensing dependencies or vendor lock-ins.
How does day-to-day collaboration work in practice?
We operate 100% remote, digital, and async-first via GitHub, Linear, Notion, and Loom. Touchpoints are focused into compact, outcome-driven sprint reviews, eliminating costly travel and meeting overhead.
Do you provide ongoing support and SLAs after launch?
Yes. Through our transparent SLA packages starting at 350 € / month, we provide continuous uptime monitoring, encrypted security backups, Web Application Firewall (WAF) tuning, and core framework updates.
