Process
Our workflow removes ambiguity: full scoping, clear milestones, structured feedback and dedicated in-house QA at every stage. This keeps delivery predictable and prevents the delays most Shopify projects run into.
Shopify Development and Design Services
We design and build Shopify stores that load fast, convert and scale with your business, with every line of code created by our in-house team, not based on templates.
Fast and stable Shopify stores built to perform.
Shopify Web Development Agency
Out-of-the-box themes and heavy app stacks slow sites down, limit what you can do and hold back conversions. If your store feels restrictive or underperforms despite good traffic, the issue is rarely your marketing. It’s the way your Shopify site has been designed and developed.
We create fully custom Shopify designs, streamline your tech stack and build a site that works the way your business needs it to. The result is a faster, more scalable ecommerce store that turns more of your existing visitors into customers.
Shopify is one of the strongest ecommerce platforms available but most stores never reach their potential. Themes, bloated apps and restrictive builds often create slow load times, fragile layouts and poor UX that hurt conversion and limit growth.
These issues aren’t caused by Shopify itself. They happen when a store is assembled from templates, overloaded with add-ons or built without considering performance, SEO or long term scalability. With the right design and development, Shopify becomes fast, flexible and easy to manage.
Design
We build fully custom Shopify designs. Every page is shaped around user behaviour and CRO principles to increase conversion and strengthen your brand experience. You see interactive prototypes before development begins, including real interactions, hover states and mobile behaviour.
Development
We streamline your store by removing unnecessary apps, reducing code bloat and building features properly. The result is a fast, stable Shopify site that’s easy to update and scale.
Growth
We optimise structure, page speed , internal linking and on-page elements so your Shopify store performs commercially and ranks more effectively. Better UX, cleaner code and stronger SEO foundations means your marketing budget works harder.

The Real Benefits of a Well-Built Shopify Store
Fast, secure and stable.
Shopify provides a secure, fully hosted infrastructure. When combined with clean, efficient development, your store loads quickly and runs reliably even under heavy traffic.
Flexible without the bloat.
Most stores rely on too many apps. We streamline your setup so features are built natively where it makes sense, reducing code weight and improving performance.
Built-in analytics that matter.
Shopify’s reporting becomes far more valuable when your structure is clean. You get clearer insights into product performance, customer behaviour and revenue drivers.
Simple to manage at scale.
With a well-planned backend and intuitive content controls, you can update products, pages and campaigns confidently without risking broken layouts or inconsistent design.
Shopify Designers and Developers
Choosing the right Shopify agency matters. Most problems store owners face (slow loading, restrictive templates, confusing backends and unreliable developers) come from sites built without planning, documentation or proper design and development processes. We fix that by doing things the right way, from day one.
At ALT Agency, everything is handled by our Birmingham-based team in-house: design, development, project management and QA. You work directly with the people building your store, not account managers relaying messages. Communication is fast, feedback is simple and every stage is transparent so you always know what’s happening and why.
Every page is designed to convert, every component is stable and scalable, and your CMS is structured so you can update content safely without needing a developer. The result is a store that loads quickly, feels polished and supports your long term growth.
Plus, if a required feature proves technically unachievable, our money back guarantee removes the risk from your investment.
What to Expect
A Shopify build only works if the process is clear and the execution is accurate. We scope every requirement upfront so risks, edge cases and technical constraints are understood early, keeping delivery predictable and avoiding mid-project surprises.
You work directly with our in-house Shopify designers, Shopify developers and project manager. Communication is quick, feedback is simple and every stage is transparent, so your store launches on time, performs reliably and is easy for your team to manage.
Performance
We prioritise speed, stability and scalability. Clean code, smart architecture and minimal app reliance mean your store loads quickly. We also reduce security risks by replacing unstable plugins, hardening your setup and keeping the codebase lean and maintainable.
Support
After launch, we’re on hand with fast responses, ongoing website maintenance and guidance whenever your store evolves. No ticket queues, no slow fixes, just direct access to the specialists who built your site.

Start Your ProjectFAQs
Can Shopify use a custom design instead of a template?
Yes. Shopify supports fully custom designs. We create your store layout, components and interactions from scratch, then code it into Shopify without relying on themes. You get a conversion-focused design rather than a template shared across hundreds of stores.
Is Shopify secure for ecommerce?
Yes. Shopify is a fully hosted platform, so security, patching and fraud prevention tools are managed for you. PCI compliance, encrypted checkout and automatic updates come as standard, reducing the risk of breaches and removing the maintenance burden from your team.
Can Shopify handle custom functionality or integrations?
In most cases, yes. Shopify has a strong API and supports custom apps, third-party integrations and bespoke features when the native platform isn’t enough. We build custom functionality or connect external systems so your store works exactly as your business requires.
Can you migrate my existing site to Shopify?
Yes. We handle full migrations from platforms like WooCommerce, Magento, custom builds and legacy systems. That includes products, customers, orders, redirects and structured content. The goal is a clean move with no loss of SEO value, data integrity or revenue.
Will my Shopify store load fast?
It can if it’s built properly. We avoid bloated themes, unnecessary scripts and heavy app stacks. Clean code, optimised images and smart architecture mean your store loads quickly, improving conversion rates and search performance across all devices.
What is the process for launching a Shopify store with ALT Agency?
We start with a scoping workshop to define goals, functionality and risks. Then we design every key page, build it exactly to the design, and test everything in-house before launch. You get clear communication, predictable timelines and a store ready to perform as soon as it goes live.
