From fully custom Liquid theme development and Shopify Plus B2B commerce setup to checkout extensibility, multi-store expansion, and platform migrations — we deliver end-to-end Shopify solutions engineered for performance, flexibility, and long-term commercial growth. We serve brands and agency partners across the USA, UK, Canada, Australia, New Zealand, and Europe.

End-to-End Shopify & Shopify Plus Solutions

Our Shopify & Shopify Plus Development Services

From bespoke Shopify theme builds and Shopify Plus enterprise setups to third-party integrations, platform migrations, and ongoing performance optimization — explore the complete range of Shopify development services we deliver for brands and agencies worldwide. We build fully custom Shopify and Shopify Plus storefronts that stand out from template-based competitors — engineered in Liquid with clean, scalable code and pixel-perfect design fidelity.

Custom Shopify Theme Development (Liquid)

We build fully custom Shopify themes from scratch using Liquid — Shopify’s native templating language — tailored precisely to your brand identity, product catalog structure, and conversion goals. Unlike off-the-shelf themes, our custom Liquid builds are lean, fast, and architecturally clean — with no bloated feature sets or visual compromises. Every section, snippet, and layout block is hand-coded to give you a unique storefront that performs as well as it looks, and scales cleanly as your product range grows.

Shopify 2.0 Online Store Development

We build modern Shopify Online Store 2.0 themes that take full advantage of Shopify’s section and block architecture — enabling merchants to customize layouts, add content sections, and manage the storefront independently without developer involvement. Our OS 2.0 builds include a well-organized JSON template structure, flexible section schema definitions, and a theme customizer experience tailored to your client’s content management needs.

Dawn Theme Customization & Development

We customize and extend Shopify’s Dawn theme — the official Shopify 2.0 reference theme — to create a unique, brand-aligned storefront while preserving Dawn’s performance architecture and customizer compatibility. Our Dawn customizations range from visual design overrides and custom section additions to advanced Liquid logic, metafield integrations, and custom JavaScript functionality that goes beyond what the native theme editor can achieve.

Custom Sections, Blocks & Snippets

We develop custom Shopify sections, blocks, and reusable Liquid snippets that expand your theme’s capabilities without overriding core theme code. Custom sections allow merchants to build unique page layouts through the Shopify theme editor — without relying on a developer for routine content changes. Our snippet library approach keeps theme code organized, maintainable, and easy to extend as your store’s requirements evolve.

Product Page & Collection Page Development

We build high-converting custom product and collection page templates — going far beyond the default Shopify layout to deliver enhanced product galleries, variant-aware content sections, trust signal placements, complementary product displays, size guide integrations, and dynamic metafield-driven content. Our collection page builds include advanced filtering, sorting, infinite scroll, and content-above-filter layouts that improve product discovery and drive higher category page conversion rates.

Cart & Checkout Customization

We optimize the Shopify cart and checkout experience to reduce abandonment and increase completed purchase rate. For standard Shopify, this covers AJAX cart drawer customization, cart upsell widgets, sticky cart bars, and checkout page CSS styling. For Shopify Plus merchants, we build full Checkout Extensibility implementations using Checkout UI Extensions — adding custom fields, post-purchase offers, dynamic content blocks, and branding customizations directly within the Shopify checkout flow.

Shopify Plus Store Development & Configuration

We build and configure enterprise-grade Shopify Plus stores end-to-end — from initial store architecture and theme development through payment provider configuration, shipping setup, tax compliance, and launch. Our Shopify Plus development process accounts for high traffic volumes, complex product catalogs, multi-channel sales, and the advanced automation capabilities exclusive to the Shopify Plus plan — delivering a store built to scale from day one.

Shopify Plus B2B Commerce Development

We build native Shopify Plus B2B commerce solutions using Shopify’s dedicated B2B features — including Company and Location setup, customer-specific price lists, net payment terms, minimum order quantity rules, quantity pricing rules, draft order workflows, and B2B-only catalog visibility. Whether you operate a pure B2B wholesale model or a combined B2B and D2C store, we configure and develop a Shopify Plus B2B experience that makes ordering effortless for your trade customers.

Checkout Extensibility & Checkout UI Extensions

We build Shopify Plus Checkout Extensibility implementations using Checkout UI Extensions — Shopify’s official method for customizing the checkout without modifying checkout.liquid. Our Checkout UI Extension builds include custom fields, order note inputs, delivery instructions, custom banners and promotional messaging, loyalty point displays, post-purchase offer pages, and thank-you page extensions. This approach is future-proof, fully supported by Shopify Plus, and maintains full compatibility with Shop Pay and other accelerated checkout methods.

Shopify Flow Automation & Custom Workflows

We design and implement Shopify Flow automation workflows for Shopify Plus merchants — automating repetitive business processes including order tagging and routing, fraud risk flagging, inventory threshold alerts, customer segmentation triggers, B2B order approval workflows, email and Slack notifications, and loyalty tier management. Well-designed Flow automation reduces manual operational overhead and enables your store to handle high order volumes without proportional increases in staff time.

Shopify Markets & Multi-Region International Commerce

We configure and develop Shopify Markets implementations for brands selling to international customers across multiple countries and currencies. Our Shopify Markets setup covers domain and subdirectory structure for each market, language and currency localization, market-specific pricing, payment method configuration by region, duty and import tax display, and market-specific product availability rules — giving your international customers a fully localized shopping experience while operating from a single Shopify admin.

Shopify Plus Launchpad & Campaign Automation

We configure Shopify Plus Launchpad to manage high-stakes sales events and product launches — including flash sales, Black Friday / Cyber Monday campaigns, new product drops, and seasonal promotions. Launchpad enables you to schedule theme changes, price adjustments, discount activation, and app settings changes to go live simultaneously at a precise time — and revert automatically after the campaign ends — without manual intervention during your most critical traffic periods.

Shopify Plus Multi-Store Expansion Setup

We architect and build Shopify Plus multi-store setups for brands operating multiple storefronts — across different regions, brands, customer segments (D2C vs B2B), or product lines. Our multi-store implementations define a clear store architecture strategy, configure shared apps and integrations efficiently, establish consistent brand standards across storefronts, and set up centralized reporting where possible — giving enterprise brands the flexibility of multiple stores without disproportionate management complexity.

Shopify Plus Custom App & API Development

We develop custom Shopify apps and private API integrations for Shopify Plus merchants requiring functionality beyond what the app store provides. Our custom app development covers Shopify Admin API, Storefront API, GraphQL Admin API, and Webhooks — enabling deep integration with ERP systems, custom inventory management, bespoke pricing engines, product configurators, and unique checkout experiences that define your brand’s competitive advantage in the market.

Payment Gateway Integration & Configuration

We integrate and configure all major and regional payment gateways for Shopify and Shopify Plus — including Stripe, PayPal, Braintree, Klarna, Afterpay/Clearpay, Square, Authorize.Net, Worldpay, and regional payment solutions specific to the USA, UK, Canada, Australia, and Europe. We configure multi-currency checkout, 3D Secure authentication, express payment options (Apple Pay, Google Pay, Shop Pay), and B2B payment terms — delivering a payment experience that maximizes checkout completion rates for your target markets.

Shipping, Logistics & Carrier Integration

We integrate real-time shipping rate calculators and logistics carrier connections into your Shopify store — including UPS, FedEx, DHL Express, Royal Mail, Australia Post, Canada Post, Sendle, and third-party logistics (3PL) providers. We configure shipping zones, weight and dimension-based rates, free shipping thresholds, local delivery options, and click-and-collect setups. For Shopify Plus, we integrate Shopify Carrier Service API connections for custom real-time rate generation from your logistics platform.

CRM & ERP System Integration

We connect your Shopify or Shopify Plus store with your CRM or ERP system — including Salesforce, HubSpot, Zoho CRM, NetSuite, SAP, Microsoft Dynamics, and Brightpearl. Integration ensures your customer records, order data, inventory levels, and financial transactions stay synchronized in real time between Shopify and your business systems — eliminating manual data entry, reducing errors, and giving your operations team a single source of truth across all business data.

Email Marketing & SMS Automation Integration

We integrate your Shopify store with email marketing and SMS automation platforms — including Klaviyo, Omnisend, Mailchimp, ActiveCampaign, and Attentive. We configure abandoned cart recovery, welcome series, post-purchase sequences, browse abandonment flows, back-in-stock alerts, win-back campaigns, and SMS transactional notifications — turning your Shopify customer data into a structured, automated revenue-generating marketing operation rather than a disconnected list of contacts.

Subscription & Recurring Revenue Development

We implement Shopify subscription and recurring revenue solutions — using Recharge, Seal Subscriptions, Bold Subscriptions, or custom Shopify app implementations depending on your requirements. Our subscription setup covers product subscription configuration, billing cycle options, free trial periods, subscriber portal functionality, pause and skip options, and dunning management for failed payments — delivering a complete recurring revenue infrastructure for subscription box, replenishment, or membership models.

Upsell, Cross-Sell & Product Bundle Configuration

We implement revenue-increasing upsell, cross-sell, and product bundle features throughout your Shopify store — covering in-cart upsells, post-purchase offer pages (using Shopify Plus Checkout Extensibility or ReConvert), frequently bought together widgets, product bundle builders, and volume discount tiers. Every configuration is focused on measurable average order value improvement, not just feature installation — we test placement, timing, and offer logic to maximize commercial impact.

Loyalty Program & Customer Retention Integration

We integrate and configure customer loyalty and rewards programs for Shopify stores — using platforms including LoyaltyLion, Smile.io, Yotpo Loyalty, and Okendo. Our loyalty integration service covers points program setup, reward tier configuration, referral program activation, loyalty widget placement, and integration with your email marketing platform for loyalty-triggered communications — building a retention layer that increases customer lifetime value and repeat purchase frequency.

Review, Social Proof & UGC Integration

We integrate product review and user-generated content (UGC) platforms into your Shopify store — including Yotpo, Judge.me, Okendo, Loox, and Trustpilot. Review integration covers structured data markup for review rich snippets in Google search results, strategic review widget placement on product and collection pages, automated post-purchase review request emails, and UGC gallery displays. Social proof integration is one of the highest-ROI eCommerce optimizations — and we implement it properly to maximize its conversion impact.

WooCommerce to Shopify Migration

We handle complete WooCommerce to Shopify migrations — transferring all products (including variants, images, custom fields, and metafields), customer records, order history, blog content, discount codes, and SEO metadata. We implement 301 redirects for all changed URLs, preserve your existing SEO equity, and conduct post-migration data integrity verification before go-live. Our migration process uses a staging environment for testing, ensuring your live store remains operational throughout the transition with zero data loss.

Magento / BigCommerce / PrestaShop to Shopify Migration

We migrate eCommerce stores from Magento, BigCommerce, PrestaShop, OpenCart, and other platforms to Shopify or Shopify Plus — handling catalog mapping, customer data migration, order history transfer, custom field mapping, URL redirect implementation, and payment gateway reconfiguration. For complex Magento 2 or enterprise platform migrations, we conduct a full pre-migration architecture review and build a structured migration plan that accounts for custom functionality, integrations, and business continuity requirements.

Shopify Core Web Vitals & Speed Optimization

We optimize your Shopify store’s Core Web Vitals performance scores — targeting LCP under 2.5 seconds, CLS below 0.1, and INP under 200ms to meet Google’s performance thresholds. Our Shopify speed optimization process covers unused app script removal, Liquid render-blocking elimination, critical CSS identification, JavaScript deferral, image format conversion to WebP/AVIF, lazy loading implementation, font display optimization, and CDN configuration — delivering measurable improvements in Google PageSpeed Insights scores and real-user performance.

Shopify Technical SEO Optimization

We implement Shopify-specific technical SEO improvements that improve your store’s organic search visibility — covering canonical tag configuration, duplicate content resolution (collection and product URL handling), structured data markup (Product schema, BreadcrumbList, Organization), sitemap configuration, robots.txt optimization, hreflang implementation for international stores, internal linking architecture, and Shopify’s known SEO limitations workaround strategies. We focus on technical SEO factors within Shopify’s architecture that have measurable impact on organic ranking performance.

Shopify Store Audit & Health Check

We conduct a comprehensive Shopify store audit covering theme code quality, app performance impact, Core Web Vitals scores, technical SEO issues, conversion rate bottlenecks, checkout flow friction, mobile experience quality, accessibility compliance, and security configuration. You receive a prioritized report with severity-rated findings and specific implementation recommendations — giving you a clear, actionable roadmap for store improvement whether you’re planning a redesign or optimizing a live store.

Shopify Analytics & Conversion Tracking Setup

We configure complete eCommerce analytics and conversion tracking for your Shopify store — including Google Analytics 4 (GA4) enhanced eCommerce events, Google Tag Manager container setup, Meta (Facebook) Pixel and Conversions API, TikTok Pixel, Klaviyo analytics, and custom conversion event tracking. Accurate analytics data is the foundation of every profitable Shopify optimization decision — and our tracking setup ensures your purchase, add-to-cart, checkout initiation, and refund events are captured correctly across all platforms.

Shopify Maintenance, Support & Bug Fixing

We provide ongoing Shopify maintenance and dedicated support for agencies and store owners who need a reliable technical partner. Our maintenance service covers Shopify and app update management, theme compatibility verification, proactive bug identification and resolution, performance monitoring, content and product updates, and on-demand development for new features or integrations. We offer flexible monthly retainer packages and pay-as-you-go support depending on your store’s development cadence and operational requirements.

White Label Shopify Development for Agencies

We operate as a white-label Shopify development partner for agencies of all sizes — building, customizing, and maintaining Shopify stores under your agency brand with complete confidentiality. We sign NDAs on request, communicate through your preferred channels (Slack, email, project management tools), and never contact your end clients directly. Whether you need a one-off Shopify project delivered under your brand or a dedicated Shopify development team for ongoing client work, we provide reliable, professional-quality output that your clients experience as your own.

Every layout is carefully developed to ensure responsiveness, speed, and a seamless shopping experience. We also build custom sections and reusable modules to give you full control over your content without technical effort.

WPCodingLoft - FAQ

Frequently Asked Questions About Our Shopify Plus Development Services

What is the difference between Shopify and Shopify Plus?

Shopify is the standard eCommerce platform plan suitable for most growing online stores. Shopify Plus is Shopify’s enterprise tier — offering advanced features including Checkout Extensibility for custom checkout builds, Shopify Flow for workflow automation, B2B native commerce tools, Shopify Markets for international selling, multi-store management, higher API call limits, a dedicated merchant success manager, and lower transaction fees at high revenue volumes. Shopify Plus is typically suited for brands generating over $1M USD annually or requiring enterprise-level customization and automation.

Do I need Shopify Plus for checkout customization?

Yes. Since Shopify deprecated checkout.liquid in August 2024, Checkout Extensibility using Checkout UI Extensions is the only supported method for customizing the Shopify checkout beyond basic CSS branding. Checkout Extensibility is an exclusive Shopify Plus feature. If you need custom fields, post-purchase offers, loyalty displays, or advanced checkout logic, Shopify Plus is required.

Can you migrate our existing WooCommerce or Magento store to Shopify Plus?

Yes. We handle full platform migrations to Shopify and Shopify Plus from WooCommerce, Magento, BigCommerce, PrestaShop, OpenCart, and other platforms. Our migration service includes product, customer, order, and content transfer — plus full URL redirect implementation to preserve your existing SEO rankings. We conduct all migration work on a staging environment before go-live to ensure zero data loss and minimal business disruption.

How long does a custom Shopify store development take?

Timeline depends on project scope. A custom Shopify theme build based on an approved design typically takes 2–4 weeks. A full Shopify Plus store setup with custom theme, third-party integrations, and B2B configuration typically takes 4–8 weeks. We provide a detailed project timeline after reviewing your requirements, with defined milestones throughout the build.

Do you build Shopify stores for agencies on a white-label basis?

Yes. We work as a white-label Shopify and Shopify Plus development partner for agencies worldwide. We deliver all work under your agency brand, sign NDAs on request, communicate through your preferred project management tools, and never contact your end clients. Many of our long-term partners are agencies that use WPCodingLoft as their dedicated Shopify development team.

Can you build headless Shopify stores using Hydrogen?

Yes. We build headless Shopify storefronts using Shopify Hydrogen and Remix — Shopify’s official React-based headless commerce framework. Headless architecture is ideal for brands that need maximum frontend performance, complete creative freedom, or deeply custom interactive experiences that standard Liquid themes cannot deliver. We advise on whether headless is the right approach for your specific project requirements before recommending it.

Do you offer ongoing Shopify support and maintenance?

Yes. We offer flexible Shopify maintenance and support packages for agencies and store owners — covering app updates, theme maintenance, bug fixing, performance monitoring, and on-demand development. We offer both monthly retainer packages and pay-as-you-go support depending on your store’s needs and development cadence.

Which countries do you serve for Shopify development?

We serve Shopify and Shopify Plus clients directly and through agency partnerships across the USA, UK, Canada, Australia, New Zealand, and Europe. We understand the payment gateway, shipping carrier, tax compliance, and localization requirements for each of these markets — and configure Shopify stores accordingly for international commercial success.
