Your Shopify Store Looks Professional. But Is It Actually Built to Convert?
Default Shopify themes get you online fast. They don’t get you performance that scales, tracking that reveals customer behaviour, or architecture that supports growth.
Most businesses launch with out-of-the-box functionality and discover limitations only when they’re already losing revenue. Checkout friction costing 20% of potential sales. Performance issues driving mobile visitors away. Analytics blind spots hiding which products actually drive profit.
We build Shopify stores as performance-engineered systems – fast, measurable, and architected for the customer journeys that convert.
Let us audit your Shopify implementation and we’ll show you what you’re missing.

Most businesses treat Shopify as a template platform – pick a theme, add products, launch. Then they discover their store can’t adapt to their actual business model without expensive workarounds.
Here’s what a wonderful Shopify implementation delivers:

Implementation takes approximately 12 weeks from kickoff to launch for most stores. Week 1-3 is discovery and architecture planning. Weeks 4-9 are theme development, custom functionality, and integration work. Weeks 10-12 are optimisation, testing, and team training.
Timeline extends if you’re migrating from another platform (add 2-3 weeks for data migration) or building highly complex custom functionality. We map the complete timeline during discovery so you know exactly what to expect.
We don’t rush – performance engineering means getting foundations right, not launching fast then fixing problems.
Project costs vary significantly depending on complexity, custom functionality requirements, and integration needs.
Cost drivers include: custom functionality requirements (product configurators, subscription logic, B2B portals), number of app integrations, migration complexity from previous platforms, extent of performance optimisation needed, and level of analytics implementation.
We provide fixed-price quotes after discovery call once we understand your specific requirements. Every project is different, and a proper discovery conversation ensures accurate pricing with no surprises.
Yes. Most of our Shopify work involves improving existing stores rather than building from scratch.
We audit your current implementation identifying performance bottlenecks, functionality gaps, and tracking blind spots. Then we methodically address issues – theme refactoring for performance, custom functionality development, analytics implementation, or app integration improvements.
This approach often delivers better ROI than rebuilding because you maintain your existing content, product data, and SEO equity whilst fixing the technical problems holding you back.
Yes. Shopify Plus unlocks capabilities that standard Shopify can’t support – custom checkout modifications, wholesale channels, advanced automation, and multi-store management.
We help businesses evaluate whether Plus makes sense for their growth trajectory. For many, the monthly cost isn’t justified by the additional capabilities. For others, checkout customisation alone pays for the upgrade through conversion improvement.
If you’re already on Plus, we maximise the platform through custom Scripts, Flow automation, checkout modifications, and advanced app integrations that Plus enables.
Integration requirements depend entirely on your business model, but common platforms include:
Marketing & Analytics: Klaviyo (email), Google Analytics 4, advertising platforms (Meta, Google Ads), loyalty programs (LoyaltyLion, Smile.io), personalisation (Nosto)
Operations: Inventory management (OrderWise), fulfilment platforms (BetterShipping, Shoplift), ERP integration, accounting software (Xero, QuickBooks), customer service (Gorgias), data management (Matrixify)
Conversion: Reviews platforms (Judge.me, Yotpo), subscription management (Recharge, Bold), size/fit recommendations, product customisation tools
We evaluate apps based on performance impact, data quality, and whether they solve actual business problems rather than adding features you won’t use.
Yes. Training is included in every implementation through both live sessions and custom written documentation.
Live training covers: Shopify admin navigation, product management workflows, collection and discount configuration, theme customisation basics (what you can safely change), and how to interpret your analytics setup.
Custom written guides are tailored to your specific implementation, meaning new team members can onboard themselves and you can refresh knowledge months later when implementing new features. Documentation includes step-by-step guides with screenshots for common tasks.
The goal isn’t making you dependent on us – it’s ensuring your team owns the knowledge to run and grow your store confidently.
Yes. We’ve migrated stores from WooCommerce, Magento, BigCommerce, and custom platforms to Shopify.
Migration involves more than moving product data. We map your current functionality to Shopify equivalents, identify gaps requiring custom development, migrate customer data and order history, implement URL redirects preserving SEO equity, and rebuild analytics tracking matching (or improving) your current measurement.
Most migrations take 12-16 weeks depending on catalogue size and functionality complexity. We maintain your current store operational until the Shopify version is thoroughly tested and ready to launch.
Performance engineering starts at architecture, not optimisation afterwards.
We implement: image optimisation with modern image formats such as WebP and lazy loading, critical CSS inlining and script deferral, app script management (many apps inject unnecessary JavaScript), theme code optimisation removing unused Shopify features, and CDN configuration for global content delivery.
Target metrics: LCP (Largest Contentful Paint) under 2 seconds, INP (Interaction to Next Paint) under 200 milliseconds, CLS (Cumulative Layout Shift) under 0.1. These aren’t arbitrary – they’re Google’s Core Web Vitals thresholds that affect both search rankings and conversion rates.
We validate performance across actual devices, not just lab testing. Mobile performance matters more because that’s where most traffic occurs.
Standard Shopify analytics captures transactions but misses the customer behaviour that predicts them. We implement measurement architecture revealing what actually drives conversions.
GA4 setup with enhanced e-commerce tracking: product impressions, add-to-cart events, checkout progression, and purchase completion. Custom events tracking product interactions (quickview usage, size guide opens, review reads) that correlate with conversion. GTM implementation enabling tag management without touching theme code.
Server-side tracking implementation improving tracking accuracy by 10-30% compared with standard Google & YouTube app implementations. This captures data that browser-based tracking misses due to ad blockers, consent restrictions, and technical limitations.
Data layer architecture capturing: product categories, bundle configurations, customer segments, discount usage, and cross-sell performance. This structure enables segmentation, attribution, and optimization that default tracking can’t support.
Integration with advertising platforms for accurate ROAS measurement and CRM systems for customer lifetime value analysis.
Yes. Shopify’s flexibility comes from its app ecosystem and custom development capabilities – but most businesses don’t know how to leverage these properly.
Custom functionality we’ve built: product configurators with dynamic pricing, subscription management with custom billing logic, B2B wholesale portals with tiered pricing, appointment booking integrated with inventory, bundle builders with compatibility rules, and size recommendation tools using customer data.
Implementation approach depends on requirements: sometimes existing apps configured properly solve the need, sometimes custom theme code delivers the capability, sometimes we build custom Shopify apps for complex functionality.
We evaluate solutions based on: maintenance requirements, performance impact, cost versus value, and whether the functionality genuinely improves customer experience rather than adding complexity.
Yes. Most clients continue with monthly retainers for ongoing optimisation, performance monitoring, and strategic development.
Typical support includes: performance monitoring and optimisation as catalogue grows, conversion rate optimisation testing, analytics review and insight generation, security updates and app management, and strategic consultation on growth initiatives.
This isn’t just maintenance – it’s continuous improvement ensuring your store evolves with your business.
Alternatively, we provide comprehensive documentation enabling your team to manage independently with ad-hoc support available when needed.
Accessibility expands your market and improves SEO – it’s not just compliance. 15-20% of the population has disabilities affecting how they interact with websites. Accessible stores capture this revenue whilst competitors exclude it.
We implement: semantic HTML structure, keyboard navigation support, screen reader compatibility, colour contrast meeting WCAG 2.1 AA standards, focus indicators for navigation, and form validation accessible to all users.
Testing involves actual assistive technology, not just automated scanners. Automated tools catch obvious issues but miss interaction problems real users experience.
Accessible markup also helps search engines understand content, improving SEO alongside expanding your addressable market.
Most Shopify agencies specialise in design or development. We’re performance engineers – we combine technical implementation with measurement architecture and business outcome focus.
Our development team understands conversion tracking requirements. Our analysts inform technical architecture. This integration means you don’t get a beautiful store with blind analytics.
We build Shopify stores considering: page speed impact of every feature, analytics architecture capturing business-critical behaviour, scalability as catalogue and traffic grow, accessibility expanding market reach, and maintenance requirements for your team.
You’re not buying a Shopify theme customisation. You’re getting a growth platform engineered to reveal opportunities and convert customers efficiently.
We build completely custom themes from the ground up. No reliance on existing themes with bloated functionality you’ll never use.
Custom theme development means: code optimised specifically for your performance requirements, architecture built around your product catalogue structure, functionality tailored to your exact business model, no unnecessary features slowing down your site, and complete control over future modifications.
This approach delivers exactly what you need without compromise or workarounds. Clean foundations perform better and adapt easier than starting with pre-built themes and stripping out unwanted features.
Yes. Shopify Markets makes international selling more accessible, but implementation requires careful planning around: currency conversion and pricing strategy, shipping zones and fulfilment logistics, payment methods by region, and analytics tracking maintaining accuracy across markets.
We implement: multi-currency display with proper conversion, geo-location based content and pricing, international shipping configuration, payment gateway selection by market, and cross-border tracking ensuring accurate attribution.
Analytics complexity increases significantly with international stores – you need measurement separating performance by market, currency normalisation for reporting, and attribution accounting for different customer journeys by region.
This isn’t just enabling Shopify Markets – it’s engineering an international operation that scales profitably.
