Headless e-commerce is an architecture that decouples the storefront (what customers see) from the commerce engine (inventory, checkout, payments), connecting them through APIs. This separation gives you complete control over the shopping experience while keeping the backend logic modular and replaceable.

Traditional platforms like Shopify and WooCommerce couple the frontend to the backend, limiting design freedom, checkout customization, and page performance. A headless storefront built on Next.js 16 with React Server Components renders product pages in under 300ms, directly improving Core Web Vitals scores and Google product ranking.

The business impact is measurable. Headless stores typically achieve 35–50% faster page loads than template-based alternatives, which translates to lower bounce rates and higher average order values.

For growing businesses, the architecture scales horizontally. Adding a mobile app, a B2B portal, or an in-store kiosk consumes the same commerce API without rebuilding the backend.

Cart abandonment is the single largest source of lost e-commerce revenue, with the Baymard Institute measuring the global average at 70.19%. The primary causes are forced account creation, limited payment options, and slow checkout flows. Custom checkout engineering addresses all three.

We build single-page checkout flows optimized for mobile-first interaction, where 72% of e-commerce traffic now originates. Every field, validation message, and loading state is engineered to minimize friction.

Payment integration covers both local and global providers:

• Regional: CorvusPay, WSPay, KeksPay, native integration, not third-party plugins
• Global: Stripe, PayPal, Apple Pay, Google Pay
• Multi-currency: Automatic EUR/USD/GBP processing for international sales across the EU and US markets

Guest checkout is the default. Account creation is offered post-purchase, not as a gate. This single change recovers an estimated 25% of otherwise-abandoned carts.

ERP integration in e-commerce is the direct, real-time connection between your online store and your business management system, synchronizing inventory, orders, invoicing, and shipping without manual data entry. Disconnected systems are the root cause of overselling, delayed fulfillment, and accounting errors.

We build bidirectional API connections to the ERP systems most common in the EU market:

• Inventory sync: Real-time stock levels from Pantheon, Luceed, SAP Business One, or custom ERPs reflected on the storefront within seconds
• Order processing: New orders push directly into the ERP with correct tax calculations, warehouse assignment, and invoice generation
• Logistics: Automated dispatch to DPD, GLS, DHL, and Croatian Post with tracking numbers written back to the customer's order page

A retailer processing 800+ orders/month eliminated 18 hours of weekly manual data entry after we connected their custom store to Luceed. Fulfillment errors dropped to near zero within the first month.

Every integration includes error handling, retry logic, and a monitoring dashboard so your team sees sync status at a glance.

E-commerce SEO is the practice of optimizing product pages, category structures, and technical site architecture so that search engines rank your products above competitors. Platform-based stores share templates, URL structures, and rendering limitations, custom stores do not.

A headless storefront built with server-side rendering delivers fully rendered HTML to Googlebot on the first response. No JavaScript execution required, no rendering delay. Product pages include JSON-LD Product schema with price, availability, review ratings, and brand markup, generating rich snippets that increase click-through rates by up to 30% in search results.

Category pages use faceted navigation with proper canonical tags to prevent duplicate content. Internal linking follows a silo architecture that concentrates topical authority on your highest-revenue product lines.

An online retailer migrated from WooCommerce to our custom headless architecture and saw a 150% increase in organic visibility for their primary commercial keywords within 90 days, with zero increase in ad spend.

Code ownership in e-commerce means you hold the complete source code, deploy on your own infrastructure, and pay zero percentage-of-revenue fees to any platform vendor. This is the single most impactful long-term financial decision an e-commerce business makes.

Shopify Plus charges a minimum of $2,300/month plus 0.2–0.4% transaction fees. For a store generating $1M annually, that exceeds $26,000/year before apps and integrations. WooCommerce avoids platform fees but accumulates costs through premium plugins, managed hosting, and security patching. A custom headless store eliminates all recurring platform costs after the initial build.

Scalability is architectural, not plan-dependent. Your store handles Black Friday traffic spikes through edge deployment and auto-scaling, not by upgrading to a higher pricing tier.

The ROI calculation is straightforward: custom development costs more upfront but reaches breakeven within 12–18 months for most mid-market stores, after which every month of operation is pure savings against platform alternatives.

E-commerce migration is the process of transferring an existing online store, products, customers, orders, SEO equity, and integrations, from one platform to a new architecture without losing data or search rankings. It is the highest-stakes project in e-commerce development, and the one most agencies underestimate.

What We Handle End-to-End:

• Product data migration, all SKUs, variants, images, descriptions, categories, and inventory levels transferred with zero data loss
• Order history and customer accounts, purchase history, saved addresses, and loyalty points preserved in full
• SEO equity protection, every existing URL mapped to its new equivalent with 301 redirects; current search rankings are preserved, not reset
• Payment gateway transfer. Stripe, PayPal, CorvusPay, and local processors fully connected in the new architecture
• Staff retraining, your team receives documentation and a hands-on walkthrough of the new CMS before go-live

Why Businesses Make the Switch: Platform fees compound as revenue grows. A store doing EUR 1M/year on Shopify Plus pays over EUR 22,000/year in subscription fees alone, before transaction costs and app subscriptions. A custom headless solution eliminates these recurring costs and removes every restriction on customization, scaling, and third-party integration.

Timeline: Most migrations complete in 6–10 weeks depending on catalog size. We run old and new stores in parallel during transition to eliminate downtime risk.

Custom e-commerce, Shopify, and WooCommerce each serve different stages of business growth. Custom headless development delivers maximum performance and zero recurring platform fees. Shopify provides fast setup at the cost of transaction fees and customization limits. WooCommerce offers more control than Shopify but depends on plugin quality and hosting configuration.
