Shopify Engineering

The Shopify development agency for stores that need more than a theme.

The average Shopify store converts at 1.4%. A one-second speed improvement lifts that by 20%. We build the custom storefronts, ERP integrations, and checkout flows that close the gap between your revenue and your traffic.

What we build

Custom Shopify storefronts

Theme builds and headless storefronts on Hydrogen and Remix, tuned for speed. 52% of Shopify stores fail Core Web Vitals on mobile. Yours won't. Liquid, React, or both.

Checkout optimization

70% of carts get abandoned. We build custom checkout extensions, subscription flows, and payment logic that recover the revenue you're losing right now. Shopify Plus required for full checkout extensibility.

ERP and backend integrations

Shopify talks to your ERP, PIM, and fulfillment systems without manual data entry. SAP, Microsoft Dynamics, Odoo, Plentymarkets, JTL. No more inventory mismatches at 2 AM. No more order sync failures during peak traffic.

Operations automation

Automated tagging, order routing, bundling rules, and inventory alerts. One client cut their fulfillment processing time from 3 hours to 20 minutes per day. We write the Shopify Flows and custom apps that do it.

Performance engineering

LCP under 2.5 seconds. INP under 200ms. CLS under 0.1. Real Core Web Vitals targets with real measurement. Not a Lighthouse score you ran once on your laptop.

Revenue analytics

Conversion funnels, cohort analysis, and attribution data piped into dashboards your team actually checks. Beyond what Shopify's built-in analytics shows you. GA4, server-side tracking, custom warehouses if you need them.

How we work

1

Audit

We profile your store's speed, crawl your checkout funnel, and map every integration point. You get a prioritized list of fixes ranked by revenue impact, with effort estimates. One week. Fixed price.

2

Build

Storefront performance fixes ship first because they compound. Then integrations, then checkout extensions. Every sprint ends with a demo and updated conversion baselines. You see code, not slides.

3

Measure and iterate

We track conversion rate, page speed, and integration uptime against the baselines we set in week one. If the numbers don't move, we adjust. That's the deal.

What to expect

Timeline

4-8 weeks

for most projects. Storefront-only work can ship in 3. Complex ERP migrations or full Shopify Plus rebuilds take 10-16.

Investment

From EUR 15,000

depending on scope. A performance audit alone starts at EUR 3,000. Fixed-price quotes after the audit. No hourly billing.

Your involvement

Weekly demos

plus access to someone who knows your ERP and fulfillment workflow. CET working hours. We handle the rest.

Technology

Shopify, extended

From Liquid theme work to full headless rebuilds on Hydrogen and Remix. We write the code we ship. No outsourced theme installers, no template stores.

Common questions

What Shopify technologies do you work with?

Liquid for theme development. Hydrogen and Remix for headless storefronts when you need full control over the frontend. Node.js for custom apps and integrations. GraphQL for Shopify's Storefront and Admin APIs. We handle everything from theme tweaks to full headless rebuilds and Shopify Plus customization.

Shopify Plus or standard Shopify?

Both. Plus gives you checkout extensibility, higher API limits, B2B features, and Shopify Functions. Standard Shopify handles most stores under EUR 1M annual revenue without trouble. We'll tell you which one fits during the audit. Don't upgrade just because an agency told you to.

Shopify development agency vs. freelance Shopify developer?

Freelancers work great for theme tweaks and small custom apps. A Shopify development agency makes sense when you need multiple skill sets at once: a frontend engineer for Hydrogen, a backend engineer for ERP integration, and a checkout specialist for Plus extensibility. Most stores under EUR 500k annual revenue don't need an agency. Above that, the coordination overhead of multiple freelancers usually costs more than agency rates.

How much does a Shopify development agency cost?

A performance audit starts at EUR 3,000. A custom storefront or headless build runs EUR 15,000 to EUR 80,000 depending on scope. ERP and checkout integrations are scoped separately. We give fixed-price quotes after the audit. No hourly billing, no scope-creep surprises.

When does headless Shopify make sense?

Headless makes sense when your storefront performance is fighting against the platform: 200+ products with complex filtering, animation-heavy product pages, or content sources outside Shopify like a headless CMS. For most stores under 1000 SKUs, a well-built Liquid theme outperforms a poorly-built headless setup. We wrote a full breakdown of when Shopify themes hit their limit.

Can you migrate us from Magento, WooCommerce, or Shopware to Shopify?

Yes. Most migrations take 6-12 weeks depending on catalog size, custom features, and ERP setup. We migrate product data, customer accounts, order history, URL structures with redirects, and SEO metadata. The harder part is usually the integration rewiring, not the data transfer. We've moved stores from Magento 2, WooCommerce, and Shopware to Shopify Plus without losing organic traffic.
