Custom eCommerce Development for Ambitious Brands

ECommerce is no longer just “a website with a cart.” It’s your main sales engine, customer experience hub, and the heart of your data stack. We help you build—or rebuild—that engine so it’s fast, flexible, and ready to scale. We partner with:

DTC brands launching or upgrading their flagship online store
Retailers and wholesalers moving from offline or B2B catalogues into digital commerce
Digital product and subscription businesses selling memberships, content, or services.
Founders validating new concepts who need a conversion-ready store, not just a brochure site.

Built to Maximize AOV, LTV & Conversion Rate

Your store shouldn’t just look good—it should be engineered to sell. We design and implement:

Smart product discovery: Refined collections, search enhancements, bundles, “shop the look,” and AI-powered recommendations.
Offer mechanics: bundles, volume discounts, cross-sells, upsells, and one-click post-purchase offers.
Retention engines: subscriptions, loyalty programs, referrals, back-in-stock and price-drop alerts.
Checkout optimizations: express payment options (Apple Pay, Google Pay, Shop Pay, PayPal), localized payment methods, and fewer unnecessary steps.
Analytics & experimentation: clean tracking across GA4, Meta, TikTok, Klaviyo, server-side tracking where needed, and structured A/B testing.

We align UX, engineering, and marketing so every small improvement compounds into meaningful revenue.

eCommerce Platforms & Stacks We Work With

Every brand has different needs. We help you pick and implement the stack that fits your strategy—not force you into ours.

Our eCommerce Development Process

We combine strategy, design, and engineering into a clear, collaborative process.

Discovery & Strategy

We dive into your brand, products, target customers, competitive landscape, margins, and growth goals. Together, we define the right platform, architecture, and roadmap.

UX & UI Design

We map the full journey—from first visit to repeat purchase—and design wireframes and high-fidelity layouts centered on clarity, trust, and conversion.

Technical Architecture & Integrations

We define how your store connects to inventory, ERP, PIM, CRM, marketing tools, payment gateways, and logistics providers, ensuring data flows cleanly end-to-end.

Development & Implementation

Our engineers build the storefront, custom logic, and integrations using best practices for performance, accessibility, security, and maintainability.

QA, UAT & Launch& Implementation

We rigorously test flows, edge cases, responsive behaviour, and analytics. You validate everything in staging before we coordinate a smooth launch or migration.

Optimize & Grow

Post-launch, we don’t walk away. We iterate with CRO experiments, UX enhancements, new features, content and SEO improvements, and automation built on real data.

The Fundamentals of a High-Performing Store

Before we chase shiny features, we make sure the foundations are rock-solid.

Brand-Aligned Design

A visual identity that feels premium, is unmistakably yours, and builds trust at first glance.

Mobile-First Experience

Most customers shop on their phones. We design for thumb-friendly navigation, clear CTAs, and fast mobile performance.

Clear Product Storytelling

High-impact product pages with strong imagery, benefit-driven copy, social proof, FAQs, and content that removes buying friction.

SEO & GEO-Friendly Architecture

Clean URL structures, schema markup, internal linking, and GEO-ready content so search engines and generative engines can understand and surface your products.

Operational Reliability

Inventory, orders, tax, and fulfillment flows that keep working on big promo days, not just in quiet weeks.

Security & Compliance

SSL, secure payments, privacy-conscious tracking, and best practices to protect customer data and maintain trust.

Data, Automation & AI Built In

Your store is also a data engine. We help you make the most of it.

Analytics You Can Trust

We configure GA4, server-side tracking where needed, clean event structures, and dashboards so you can see what’s actually driving revenue.

Lifecycle Automation

We design and implement flows for cart and browse abandonment, welcome series, win-backs, post-purchase education, review collection, replenishment, and VIP segments using tools like Klaviyo, HubSpot, Omnisend, and custom automations.

AI-Powered Experiences

We layer in AI where it creates real value: personalized product recommendations, on-site assistants for product questions, intelligent search, and GEO-friendly content that LLMs can easily understand and reuse.

GEO-Ready Content

We structure your product, collection, and informational content so search engines and generative engines can clearly understand what you sell, who it’s for, and what makes your brand different.

Integrations That Keep Your Commerce Stack in Sync

We connect your store with the tools that run your business:

Payments: Stripe, PayPal, Braintree, Apple Pay, Google Pay, Klarna, Afterpay, local gateways

Häufig gestellte Fragen

Do you only work with certain eCommerce platforms?

We specialize in Shopify/Shopify Plus, WooCommerce, BigCommerce, Adobe Commerce (Magento), and headless architectures built on modern frameworks like Next.js. If you’re on something more niche, we’ll evaluate compatibility during discovery.

Can you help if we already have an eCommerce store?

Yes. Many engagements begin with a store audit, performance tuning, and UX/CRO improvements on your existing store, then evolve into redesigns, new features, or platform migrations as needed.

How long does an eCommerce project usually take?

Timelines depend on scope, but most new builds or major redesigns take around 8–16 weeks from discovery to launch. Smaller sprints and CRO experiments run on shorter cycles.

Do you handle copywriting and content as well?

We can. Our team often collaborates with your internal marketing team or external partners, but we can provide conversion-oriented copy, UX microcopy, and content guidelines wherever they’re needed.

Can you integrate our ERP, WMS, or other back-office tools?

Yes. We regularly integrate stores with ERPs, inventory systems, WMS solutions, shipping tools, CRMs, and marketing platforms. During discovery we map data flows so everything stays in sync.

What happens after launch?

We prefer not to “launch and leave.” Most clients retain us for ongoing optimization, CRO, new features, and technical support, ensuring that the store keeps improving with real-world data.
