Shopify Development Services for Serious E-commerce

■ Who this is for

A good fit if you're running real e-commerce on Shopify

• DTC and e-commerce brands building or rebuilding a custom Shopify storefront
• Stores migrating from WooCommerce, Magento, OpenCart, or a custom platform to Shopify
• Catalogue-heavy stores (10K to 100K+ SKUs) that need supplier-feed automation
• Brands on Shopify Advanced or Shopify Plus needing carrier-calculated shipping rates
• Merchants that need a custom Shopify app for ERP, CRM, or marketplace integrations
• Existing Shopify stores that need ongoing engineering, performance, and feature work

■ Probably not a fit

We'll be honest if Shopify is the wrong call

• Pure marketing sites with no checkout — Shopify is the wrong tool
• Single-product, no-customisation stores that fit a pre-built theme out of the box
• Projects where a freelancer's $500 theme tweak is genuinely all you need
• Teams looking purely for the cheapest Shopify Partner bid

Online Store 2.0 themes — sections and blocks

We build new themes on Online Store 2.0 with reusable sections and JSON templates so the marketing team can compose any page from the theme editor without a developer in the loop. We avoid heavy page-builder apps that re-render half the storefront in JavaScript — they're slow, expensive, and a nightmare to maintain three years in.

Mobile-first Liquid, real Core Web Vitals

60–80% of Shopify traffic is mobile. We design every PDP and collection page for 360px before we look at the desktop layout. Lazy-loaded images using Shopify's responsive image pipeline, font subsetting, deferred third-party scripts, and a hard cap on app-injected JS. LCP, CLS, and INP are budgeted, not hoped for.

Migration to Shopify — done with the APIs

WooCommerce, Magento, OpenCart, BigCommerce, and custom platforms — we've migrated all of them. The work is more than a CSV. We map customers (with password-reset flows because hashes don't carry across), historic orders, product variants, metafields, redirects from old URLs to preserve SEO, tax zones, payment provider switching, and a rehearsed cut-over plan. We use Shopify APIs, Matrixify, and custom scripts depending on what the source platform actually exposes.

Custom Shopify apps — when an app is the right answer

When the storefront needs logic that doesn't belong in Liquid — ERP sync, CRM data exchange, billing software integration, custom merchant dashboards, marketplace exports — we build a private or public Shopify app on App Bridge and Polaris. OAuth, GraphQL Admin API, webhooks, queue-backed background jobs, and rate-limit-aware retries. Apps that survive your first Black Friday.

Supplier-feed automation for big catalogues

For stores in the tens of thousands of SKUs, the killer feature is not the theme — it's the catalogue automation. We write scheduled ingestion services that pull supplier price and stock files (CSV, FTP, API), normalise them, and push deltas into Shopify with proper rate-limit and bulk-mutation handling. We've done this for catalogues up to 70,000+ active SKUs.

Custom shipping — calculated rates on Plus / Advanced

Built-in Shopify shipping is fine for most DTC. When the store has freight, oversize items, multi-warehouse split shipments, or trade-customer pricing, we integrate third-party shipping APIs as a Shopify Custom Carrier Service so checkout returns real-time rates. This requires Shopify Advanced or Shopify Plus — we'll tell you up front whether the upgrade is worth it.

Storefront features — filters, quizzes, configurators

Custom collection filters via Shopify Search & Discovery and metafields. Branching product-finder quizzes. Photo-upload configurators on personalised products. Bundle / build-your-own kit builders. Complex pricing tools — quantity breaks, trade tiers, surcharges. We write these as Liquid sections and JS modules, not as bolt-on apps that bloat the page.

Headless when it earns it — Hydrogen / Next.js

Headless Shopify with Hydrogen (Remix) or Next.js shines when the brand needs a faster front-end, a non-Shopify CMS in front of products, or a unified app/web experience. It costs you the live theme editor, native checkout customisations, and the ecosystem of standard apps. We go headless when the product genuinely benefits — not because it's the fashionable answer.

One week. We map the catalogue, the merchandising model, the integrations the store actually has to support (ERP, marketplaces, shipping carriers, marketing tools), and the business goals behind the build. For migrations, we audit the source platform's data model. Output: a written architecture and a 90-day plan.

We choose the Shopify plan (Standard / Advanced / Plus), the theme strategy (custom Online Store 2.0 vs headless Hydrogen / Next.js), the app footprint, and the hosting story for any companion services. CI, version control, and a development store get set up before any production code lands.

Theme scaffolding, base sections, metafield model, navigation, and the Shopify admin set up the way the merchandising team will actually use it. Custom apps and supplier-feed services scaffolded with auth, queues, and logging. By the end of sprint zero, the merchant can log into a working development store.

Two-week sprints. Theme work, app work, and integrations shipped through CI. Every change reviewed. Scope changes get re-baselined at sprint boundaries, not mid-sprint. You see progress every Friday — and a working preview store you can poke at any time.

For migrations: a rehearsed dry-run on the development store, then the live cut-over with redirects, customer password-reset flows, payment provider switch, and a checklist that's been run through twice. Performance pass on Core Web Vitals, app audit, security headers, and a Black-Friday-grade load expectation.

We stay on full availability for the first month after launch. Real customers find real bugs. Then we move into the standard maintenance and feature retainer — supplier-feed scripts that need to absorb a new vendor format, theme changes around a campaign, and the occasional emergency that comes with running a real store.
