BigCommerce to Shopify Migration: When UK Brands Should Switch (2026 Guide)

Migration
Shopify

If your current eCommerce platform is limiting your growth, it's time to consider a change. Many UK brands are turning to Shopify migration services to transition from BigCommerce, seeking better scalability, enhanced user experience, and more robust sales features. This process, known as eCommerce replatforming, can be a game-changer for businesses aiming to elevate their online presence.

In this guide, we'll delve into the key differences between BigCommerce and Shopify, signs that indicate it's time to migrate, a step-by-step migration process, common challenges, and how WIRO can assist in making your transition seamless.

TL;DR

  • For most UK eCommerce brands, migrating from BigCommerce to Shopify becomes logical when performance or flexibility starts to stall
  • Shopify enables faster development cycles and easier iteration compared to BigCommerce
  • The Shopify app ecosystem is broader and more mature, supporting advanced growth use cases
  • Checkout performance on Shopify is typically stronger, improving conversion rates
  • Shopify Plus provides a clearer, more scalable growth path without heavy operational complexity
  • At scale, BigCommerce can introduce operational overhead that Shopify is designed to minimise
  • For growing UK brands, Shopify offers a more future-proof platform for performance and expansion

Key Differences Between BigCommerce & Shopify

Understanding the distinctions between BigCommerce and Shopify is crucial when considering a platform switch. Here's a comparison to help you make an informed decision:

1. User Experience and Ease of Use

Shopify is renowned for its intuitive interface, making it easier for merchants to manage their stores without extensive technical knowledge. BigCommerce, while powerful, can be more complex and may require a steeper learning curve.

2. Customisation and Flexibility

Shopify offers a vast array of themes and apps, allowing for extensive customisation to meet specific business needs. BigCommerce also provides customisation options but may require more technical expertise to implement changes.

3. App Ecosystem

Shopify boasts a robust app store with thousands of integrations, enabling businesses to enhance functionality easily. BigCommerce has a growing app marketplace but with fewer options compared to Shopify.

4. Scalability

Shopify Plus gives scaling UK brands access to advanced checkout customisation, higher API limits, automation via Shopify Flow, and dedicated platform support features we typically see BigCommerce merchants seek once turnover and complexity increase.

BigCommerce vs Shopify: What We See in Real Migrations

WIRO Testimonial Quote
At WIRO, we regularly work with UK brands migrating away from BigCommerce when customisation becomes slow, performance dips under load, or teams outgrow rigid platform constraints. In most cases, Shopify delivers faster iteration, lower maintenance overhead, and better conversion outcomes within the first 90 days post-migration.

Signs It’s Time to Migrate to Shopify

Recognising when to switch platforms is vital. Here are some indicators:

  • Limited Customisation: If your current platform restricts design or functionality enhancements, it's time to consider replatforming to Shopify.
  • Performance Issues: Slow load times and frequent downtimes can deter customers and affect sales. For UK brands, performance issues are amplified by mobile usage. Over 70% of UK eCommerce traffic now comes from mobile devices, making checkout speed and script efficiency critical during platform evaluation.
  • Complex Management: If managing your store feels cumbersome, Shopify's user-friendly interface can streamline operations.
  • Growth Constraints: If your platform can't support your business's growth, migrating to Shopify can provide the necessary scalability.

Is BigCommerce to Shopify Migration Right for You?

Shopify is a strong fit if you:

  • Are scaling beyond £1m–£20m ARR
  • Need faster CRO experimentation
  • Rely heavily on third-party tools
  • Want a simpler tech stack

BigCommerce may still suit you if you:

  • Require highly bespoke backend logic
  • Have minimal need for rapid iteration
  • Are early-stage with low complexity

Step-by-Step BigCommerce to Shopify Migration Process

Transitioning from BigCommerce to Shopify involves several critical steps:

1. Data Export from BigCommerce

Begin by exporting all essential data, including products, customer information, and order history.

2. Setting Up Your Shopify Store

Create a Shopify account and choose a plan that suits your business needs. For larger enterprises, consider Shopify Plus migration for advanced features.

3. Data Import into Shopify

Utilise tools like Matrixify to import your data into Shopify efficiently. This step is crucial to ensure a smooth transition.

4. Design and Customisation

Select a theme and customise your store to reflect your brand identity. Shopify's extensive theme library and app integrations facilitate this process.

5. Testing

Before going live, thoroughly test your store to ensure all functionalities work correctly, from navigation to checkout processes.

6. Launch

Once satisfied with the setup, launch your new Shopify store and monitor its performance closely during the initial phase.

Overcoming Common Migration Challenges

While migrating platforms can be beneficial, it's not without challenges:

  • Data Loss: Ensure all data is backed up before migration to prevent any loss.
  • SEO Impact: Preserve SEO equity through full URL mapping, 301 redirects, metadata parity, and post-migration crawl validation. In our experience, most ranking losses occur not from migration itself, but from rushed launches without redirect governance.
  • Design Discrepancies: Work with experienced Shopify migration experts to replicate your store's design accurately on the new platform.
  • Functionality Gaps: Identify any features in BigCommerce that need to be replicated or enhanced in Shopify.
