What is a Custom theme and why use it over a standard Shopify Theme
Custom Shopify themes represent the highest potential of what Shopify has to offer. They’re perfect for established brands looking to elevate their online presence, fully capturing their unique vision and delivering an advanced, tailor-made user experience.
Think of it this way: switching to a custom Shopify theme is like moving your store from a suburban street to Fifth Avenue, it positions your brand to compete at the highest level.
Standard Shopify themes are great for growing brands and can adapt to some extent as your business evolves. But there inevitably comes a point when standard themes just don’t cut it anymore, and that’s exactly when a fully customized Shopify theme becomes the right move.

6. Ongoing support
Post-launch, we’ll be on hand to help with any issues or additional features you may need.
1. Discovery and Planning
In the first stage of every Shopify project, our team focuses on comprehending your specific project and setting a definite course. Once we fully understand your requirements and objectives, we offer an initial cost estimate.
Following this, our Shopify web designers and developers concentrate on getting to know your brand, devising the website’s layout, and establishing the sitemap and overall direction of the project. This phase concludes with a detailed, priced action plan, setting the stage for moving forward to the subsequent steps.
2. Shopify Theme UX/UI Design
During the Shopify design phase, your store begins to come to life through a visual mockup. This mockup lets you see and interact with your custom Shopify theme before it’s fully developed. By the end of this stage, you’ll have a clear and accurate vision of your store, eliminating any guesswork.
We tackle this stage in sprints, enabling our development team to begin work as soon as each sprint is approved. Understanding the importance of a designer’s unique style and reputation, we collaborate with some of the top design agencies in London. This partnership ensures a wide spectrum of creative options for your store’s design.
3. Shopify Custom Theme Development
Our skilled Shopify Developers will meticulously craft and code each aspect of your custom Shopify theme, ensuring it precisely reflects the mockups while offering comprehensive control over every element.
Our commitment to perfectionism enables us to deliver a theme that not only functions flawlessly and mirrors the mockups perfectly but also offers a level of detailed control that is uncommon in most themes.
4. Theme Quality testing
Quality testing involves verifying the theme’s functionality, ensuring it accurately reflects the designs, and checking that the backend controls operate seamlessly. We regard this as a crucial element in developing a Shopify custom theme, and indeed in all our development projects.
While this step is officially positioned after the development phase, it actually occurs at multiple stages, with each delivery of a sprint by the development team.
5. Training and Tutorials
A visually appealing store loses its value if you’re unsure how to operate the theme or manage daily tasks with it. That’s why we provide comprehensive guidance on using the theme and applying its various functions.
For clients who require it, we also offer live training sessions to ensure their team is fully equipped to utilize the theme effectively.
6. Ongoing support
After your custom Shopify theme is launched, the day-to-day operation of your store begins. Rest assured, we’ll be there to support you every step of the way, whether it’s resolving issues, answering questions, or implementing new features.
Our in-depth knowledge of the theme’s structure, gained from developing it ourselves, is a significant advantage. This expertise ensures that any new features we add are seamlessly integrated and function flawlessly.

Shopify Custom Themes FAQ
What is a Shopify theme or template?
A Shopify theme (or template) defines the design and functionality of your store. Themes can be purchased from the Shopify Theme Store or custom-built. In both cases, it’s possible to modify the theme to enhance or expand its functionality.
What is a custom Shopify theme?
A custom theme means skipping commercially available templates and designing your store from scratch. These projects are fully tailor-made and often among the most complex, requiring a high level of expertise from both the design and development teams.
What are the benefits of a tailor-made Shopify theme?
A custom Shopify theme offers the highest level of user experience optimisation and brand consistency. At MM Shopy Devs, we’ve worked on many projects in this category and have seen firsthand how custom themes significantly boost conversions. These types of projects are the Formula 1 of eCommerce!
Modified commercial Shopify theme vs. fully custom theme – which is better?
A modified commercial theme is a great option for growing stores that aren’t ready for a tailor-made solution. However, once your customisation reaches around 80% of the original theme, it’s usually more efficient, better performing, and more cost-effective to build a custom theme from scratch.
Who can create (or develop) a custom Shopify theme?
In short, you need an experienced and trustworthy Shopify agency.
Custom themes are complex and require in-depth knowledge of Shopify and its framework. At MM Shopy Devs, we work exclusively with Shopify, and our team is highly specialised. We strongly recommend avoiding agencies without proven, dedicated Shopify experience. Check this article about how to choose the right Shopify Agency
Who can design Tailor Made Shopify themes?
UX Designers are the specialists responsible not only for the visual design but also for ensuring a smooth and seamless user experience.
For custom theme projects, we strongly recommend working with highly experienced designers—professionals who aren’t new to the field and can anticipate potential issues rather than cause them. Their expertise plays a key role in creating a high-performing, user-friendly store.
Modified commercial Shopify theme vs. fully custom theme – which is better?
A modified commercial theme is a great option for growing stores that aren’t ready for a tailor-made solution. However, once your customisation reaches around 80% of the original theme, it’s usually more efficient, better performing, and more cost-effective to build a custom theme from scratch.
How much does it cost to develop a custom Shopify theme?
It’s hard to give a fixed price, as it depends on the complexity of the project. However, the minimum cost typically starts at £15,000. More complex projects can easily exceed £40,000 for development alone.
This makes custom themes a viable option for larger businesses. Be cautious of cheap or unrealistic offers—agencies promising custom themes at suspiciously low prices often end up doing more harm than good to your business.
Is a custom Shopify theme harder to use?
Contrary to common belief, no. A well-built custom theme is often easier to use, with controls tailored to your business. It only becomes complicated when built by inexperienced agencies lacking the right technical and operational understanding.
