A good Shopify store does more than list products. It helps customers browse, trust and buy without friction, and it keeps working smoothly as your catalogue, traffic and team grow.
Brownrush provides Shopify development services for brands that are launching a new store, rebuilding an existing one, or adding complex functionality to a store that has outgrown its first setup. Our designers and developers have years of hands-on experience with custom storefronts, theme development, app integration, migrations and ongoing support, and we work with startups, established brands and wholesale businesses.
We start with your business goals, then choose the simplest technical route that supports them. That might be a lightly customised theme, a fully custom build, a connected set of business systems, or a headless storefront. The result is a store that is secure, fast, easy to manage and ready to grow.
What Our Shopify Development Services Include
Here is a quick overview of what we handle, from the first consultation to post-launch improvements.
- Custom store design and development
- Store setup and configuration
- Theme development and customisation
- Custom Shopify app development
- Shopify Plus development
- Shopify migration from other platforms
- Integrations with apps, ERP, CRM and other systems
- Headless Shopify development
- Performance and conversion improvements
- Support, maintenance and ongoing optimisation
- Consulting and ecommerce strategy
Custom Shopify store design and development
Your store should feel like your brand, not a borrowed template. We design and build storefronts around your brand identity, your customers’ behaviour and your commercial goals. That includes custom sections, mobile-first layouts that work on every screen, clear navigation and a simple path from first tap to completed purchase.
Our team combines design and engineering, so visual ideas are planned with real Shopify constraints in mind. We use clean code, clear structure and sensible third-party integrations so your store stays stable and easy to manage after launch.
Shopify store setup and configuration
A store that is set up correctly on day one saves you headaches later. We handle the full configuration:
- Product uploads, collections and catalogue structure
- Payment gateway integration
- Shipping zones and shipping rules
- Tax configuration
- App installations and settings
- Brand styling so the store matches your identity from the first visit
This is a fast, cost-effective way to launch a reliable store, whether you are selling your first products or moving a mature catalogue to a new platform.
Shopify theme development and customisation
Your theme shapes the first impression, page speed and how easily your team can update content. We build and customise themes using Liquid and Online Store 2.0, with reusable sections, metafields and dynamic content blocks, so your marketing team can make changes without waiting for a developer.
Depending on your goals and budget, we either customise an existing theme heavily or build a fully custom one. Either way, we focus on responsiveness, speed and a look and feel that suits your brand’s personality.
Custom Shopify app development
Sometimes standard apps do not fit how your business works. We build custom Shopify apps, both private and public, for needs such as:
- Inventory automation and synchronisation
- Subscription management
- Custom loyalty programmes
- Complex pricing rules and discounts
- Product personalisation and order bundles
- Gift registries
- ERP connections and point-of-sale workflows
We use Shopify APIs, Shopify Functions and extensions, so the logic runs securely inside Shopify instead of slowing your store down.
Shopify Plus development
As a business grows, basic features can start to hold it back. Shopify Plus development is for brands with large catalogues, complex operations, several storefronts or advanced checkout needs.
We help you set up and customise Shopify Plus with automation through Shopify Flow, checkout customisation, API integrations and B2B features such as custom pricing and wholesale workflows. Shopify has retired the old Scripts and checkout.liquid approach, so we build checkout changes with Checkout Extensibility, using checkout UI extensions and Shopify Functions. If your store still relies on legacy customisations, we can audit and rebuild them.
Shopify migration
Moving platforms is risky if it is rushed. Our migration service covers WooCommerce, Magento, BigCommerce and custom platforms, with a focus on zero data loss and minimal downtime.
We move your products, customer data, order history and content, set up URL redirects, and test everything before the switch. Your old store stays live until the new one is ready, so customers keep buying and your search visibility is protected during the transition.
Shopify integrations: apps, ERP, CRM and systems
Disconnected systems create delays, errors and manual work. We connect Shopify with the tools your business already uses, including:
- ERP and CRM platforms such as Salesforce, SAP and NetSuite
- Accounting tools such as QuickBooks
- Email and SMS marketing tools such as Klaviyo
- Inventory, fulfilment and shipping systems
- Payment gateways and analytics tools
Our integrations are built for real operating conditions. They include logging, error handling, controlled retries, monitoring and reconciliation, so a network issue or a duplicate event does not silently corrupt your orders or inventory. The goal is synchronised data and a unified view of customers, inventory and orders.
Headless Shopify development
Headless architecture separates your storefront from the commerce backend. Shopify still manages products, orders and checkout, while a custom frontend, often built with Hydrogen or another framework, delivers the shopping experience through APIs.
This route suits complex catalogues, specialised content experiences and brands that sell across several digital channels. It offers more control over performance and design, but it also adds cost and maintenance. We will tell you honestly when a native Shopify theme is the better choice.
Performance and conversion optimisation
Slow pages and confusing checkouts quietly cost sales. We improve speed, mobile responsiveness and Core Web Vitals by reviewing your theme code, apps, images, fonts and tracking scripts. We also look at navigation, product pages, calls to action and checkout steps, then simplify the friction points we find.
Every build also includes an SEO-ready foundation, such as clean URLs and sensible page structure. If you need a dedicated search growth plan after launch, that is handled as a separate service.
Support, maintenance and ongoing optimisation
Launch day is not the finish line. We offer ongoing support covering bug fixes, app updates, security updates, performance monitoring and troubleshooting, plus new features as your needs change. We catch issues early, respond quickly and keep your store current.
Consulting and ecommerce strategy
If you are not sure where to start, our consultants can help. We run a discovery assessment, review your goals, audience and existing systems, and give clear recommendations on architecture, platform choices and priorities. You leave with a roadmap for your ecommerce journey, whether you build with us or not.
AI-powered Shopify development
AI is changing how stores sell. We can add AI-driven product recommendations, smart upsells, abandoned cart recovery, adaptive search and personalised shopping journeys, and connect your store with Shopify tools such as Sidekick and Shopify Magic. We use AI where it improves results, and we always keep a developer in charge of business logic.
Why Choose Shopify for Your Online Store?
Shopify is popular for good reasons. It gives growing brands:
- Customisation: tailor colours, fonts, images and layouts to match your brand, with room for advanced features
- A large developer community: plenty of expertise, tools and proven solutions
- Global selling: support for multiple currencies, taxes and shipping options
- Reliable infrastructure: hosting, security, uptime and a PCI Level 1 compliant checkout
- Integrations: a wide app ecosystem for unique features and complex processes
- Steady innovation: new features arrive continually without disrupting your store
It also includes built-in blogging, coupon codes, gift cards, unlimited products and mobile-friendly themes, so you can start simply and scale later.
Shopify or Shopify Plus?
The right plan depends on your order volume, operational complexity, checkout needs, automation requirements and long-term plans. Standard Shopify suits small to mid-sized businesses with built-in ecommerce features. Shopify Plus adds advanced checkout customisation, Shopify Functions in custom apps, multiple storefronts, B2B features and more room for high-volume brands. We will help you choose based on your real needs, not the most expensive option.
Shopify Development for B2B, B2C, D2C and Wholesale
Different buyers need different experiences. We build stores for wholesalers, consumer brands and businesses that serve both, sometimes from one backend with two buyer experiences.
- B2B and wholesale: account-specific catalogues, negotiated pricing, pricing tiers, bulk ordering, net terms, multi-location ordering and instant quote workflows
- B2C: quick navigation, clear product discovery, smooth category flow and fast checkout to reduce drop-offs
- D2C: subscriptions, campaigns, loyalty and retention features that encourage repeat purchases
Shopify solutions for every industry
Every market has its own demands, so we shape features around your sector:
- Fashion and apparel: size guides, lookbooks, predictive recommendations and virtual try-on integrations
- Beauty, health and wellness: subscription boxes, bundle builders, loyalty campaigns and compliance-ready checkouts
- Food and beverage: delivery integrations, age verification, stock tracking and subscription renewals
- Home and furniture: bulk ordering, AR product previews and custom configurators
- Electronics and tech: comparison tools, warranty registration and B2B pricing tiers
- Sports and fitness: loyalty points, memberships and class bookings
- Jewellery and luxury: immersive storefronts, virtual try-ons and custom builders
- Manufacturers and distributors: dealer workflows, ERP connections and inventory visibility
Why Shopify Stores Stop Growing, and How We Fix It
Most stalled stores share a few common problems. Here is what we look for.
Pages that take too long to load
Slow pages lose customers on every device, especially on mobile. We trim heavy scripts, optimise images and fonts and review apps that add weight.
Shoppers leaving without buying
Complicated checkouts, hidden costs and weak payment options push buyers away. We rebuild checkout flows, remove friction and make mobile checkout simple.
Poor architecture and integration problems
Stores built without a plan struggle when traffic or catalogues grow. Disconnected systems create manual work and silent failures. We design scalable architecture and use API-based integrations with validation layers so data stays accurate.
A weak shopping experience
Poor navigation and slow search frustrate visitors. We improve product discovery, search and recommendations to keep customers engaged and returning.
Global expansion without a plan
Selling in new markets needs localised storefronts, multi-currency checkout and region-specific content. We set these up so your store feels native to each audience.
Too much manual work behind the scenes
If your team copies orders, inventory or shipping updates by hand, mistakes are inevitable. We connect your systems so updates happen automatically.
Our Shopify Development Process
A clear process keeps projects predictable. For a typical new store, we plan for about six to ten weeks, depending on scope and complexity.
- Discover: We study your growth goals, products, target customers and competitors, then plan the technology stack and agree on a roadmap.
- Design: We create wireframes, mobile-first mockups and UX flows that match your brand and support conversion.
- Build: We develop the theme, custom sections, integrations, apps and payment setup using clean, scalable code.
- Test: We run quality assurance across browsers and devices, check checkout flows and integrations, and tune speed.
- Launch: We deploy carefully, map redirects, monitor performance and provide real-time support during go-live.
- Optimise: After launch, we review performance and real customer data and plan improvements.
Larger projects, such as migrations, ERP integration or B2B functionality, take longer. You will receive a predictable schedule after our discovery phase.
Technologies we use
We work with the Shopify ecosystem and the tools around it:
- Shopify: Liquid, Hydrogen, Oxygen, Storefront API, Admin API, Checkout Extensions
- Frontend: React, Next.js, Tailwind CSS, Alpine.js
- Payments: Shopify Payments, Stripe, PayPal, Klarna, Afterpay
- Integrations: Klaviyo, Recharge, Gorgias, Yotpo, Attentive, Loop Returns
- ERP and CRM: Salesforce, HubSpot, NetSuite, SAP
- Analytics: Google Analytics 4, Hotjar, Triple Whale, Northbeam
When a project needs work outside Shopify, such as middleware, databases or backend services in Node.js, PHP or Python, we design the architecture so everything works together.
Native features, apps or custom development?
We choose the simplest option that works. Native Shopify features come first. If they are not enough, we use established apps. We build custom only when apps would force workflow compromises, create high recurring costs, slow your store down or limit data ownership. This keeps your total cost of ownership low.
Engagement Models
We adapt to your budget and timeline:
- Fixed price: clearly outlined projects with a mutually agreed budget, for building, migrating or refining a store
- Monthly retainer: dedicated hours every month for continuing guidance and changing business needs
- Build your own team: our Shopify specialists join your in-house team and blend in smoothly
Costs depend on scope, the complexity of customisations, catalogue size and integrations. After a short consultation, you receive a detailed estimate rather than a flat price sheet.

Frequently Asked Questions
What is included in Shopify development services?
Our services cover the full path from idea to selling: store setup, theme customisation and custom themes, app integrations, migrations, Shopify Plus development, custom apps, performance improvements and ongoing support. Startups and enterprise brands alike get a store that is secure, scalable and easy to manage.
Can an existing Shopify store be customised, redesigned or taken over?
Yes. We can take over a store from another agency, audit its theme, apps, integrations and technical debt, and recommend whether to keep, fix or rebuild. Many stores need only targeted fixes to navigation, product pages or speed. Others benefit from a phased rebuild that reduces risk.
Do you offer Shopify Plus development? How do you decide between Shopify and Shopify Plus?
Yes. We look at order volume, operational complexity, checkout customisation needs, automation requirements, multiple storefronts and your growth plans. If standard Shopify covers your needs, we will say so.
How long does a Shopify development project take?
A typical new store takes around six to ten weeks. Larger catalogues, custom app integrations, migrations, ERP integration or B2B functionality extend the timeline. After discovery, you receive a clear schedule.
Can you migrate my store to Shopify?
Yes. We migrate stores from WooCommerce, Magento, BigCommerce and other platforms, including products, customers, orders, content and URL redirects, with a focus on zero data loss and minimal downtime.
Do you provide ongoing Shopify support and maintenance?
Yes. We offer maintenance, updates, technical support, performance monitoring and iterative improvements, on a retainer basis if you prefer. If something breaks after launch, we help you fix it quickly.
How much does it cost to hire a Shopify developer?
It depends on project scope, the complexity of customisations and the expertise needed. We offer project-based pricing, monthly retainers and dedicated developers. After a consultation, you receive a detailed estimate.
Can you integrate Shopify with ERP and CRM systems?
Yes. We connect Shopify with ERP, CRM, inventory, PIM, shipping and payment systems through APIs and custom integration solutions.
Can you connect Shopify with NetSuite, Microsoft Dynamics, SAP, Salesforce or a custom ERP?
Yes. We work with enterprise platforms and custom business systems. We define synchronisation rules and data mappings, handle errors, manage API limits and retries, and set up logging and reconciliation so inventory, customers, orders, pricing and financial data stay consistent.
Can you work with our existing technology stack?
Usually yes. Replatforming your storefront does not mean replacing your ERP, CRM, warehouse or shipping systems. We build integrations around what you already use, including custom or legacy systems.
What makes an enterprise integration different from a basic API connection?
A basic connection moves data under normal conditions. An enterprise integration also handles failures, duplicate events, rate limits, network outages and large data volumes, using queues, controlled retries, monitoring and alerts.
Will my store use a custom theme or a modified template?
It depends on your goals, budget and functionality needs. A heavily customised existing theme can work well and launch faster. A fully custom build offers a unique layout and more control for brands with specific requirements.
Can you build a custom Shopify theme?
Yes. We build custom themes with Liquid and Online Store 2.0, designed around your brand, storefront functionality and integrations.
Should we use a Shopify theme or a headless storefront?
A native theme is simpler to host, preview, maintain and merchandise. Headless offers frontend flexibility for specialised content, multiple channels and demanding performance needs, but it adds cost and complexity. We compare both against your roadmap before recommending one.
Do you develop custom Shopify apps?
Yes. We build custom apps when standard apps cannot support your workflows, data requirements or store operations.
When do I need custom development instead of a theme and apps?
Usually when native features and existing apps force workflow compromises, such as complex pricing, product configuration, B2B purchasing, specialised fulfilment rules, ERP-driven data or custom buyer experiences.
How do you approach Shopify performance optimisation?
We review real customer journeys and Core Web Vitals, then look at JavaScript, tracking scripts, Liquid code, images, fonts, search components and third-party apps. We fix the biggest sources of overhead first and protect revenue-critical features.
What if our project needs development outside Shopify?
We can build middleware, backend services, databases and custom frontends in technologies such as Node.js, PHP, Python, .NET or Java, and connect them to Shopify through APIs, Functions and extensions.
Will AI replace Shopify developers?
AI helps with small tasks, but business logic, architecture and unexpected problems still need experienced people. We use AI to work faster while a developer stays responsible for the result.
Is Shopify development in high demand?
Yes. As more businesses move to Shopify, demand for people who can build and maintain stores continues to grow.
