BigCommerce has been great for a lot of mid-market ecommerce brands, but more & more are shifting over to Shopify and Shopify Plus. That could be due to a variety of things — from ecosystem benefits and app availability to Shopify’s better checkout conversion rates and the extended partner ecosystem. 2026 The trend of migration is picking up pace with a growing number of brands realising the competitive edge Shopify’s ecosystem provides.
If you’re thinking about migrating from BigCommerce to Shopify, this playbook will help walk you through both the strategic and tactical items that need to be addressed for a successful transition – starting with planning all the way through post-launch optimisation.
Why Brands Are Migrating from BigCommerce to Shopify
Blame it on ecosystem depth. The app marketplace on Shopify has more than 8,000 apps compared to BigCommerce’s approximately 1,200. For brands that require specialised features such as subscriptions/loyalty programs (1), advanced personalisation and internationalisation (2) capabilities, the Shopify ecosystem provides a lot more options with far higher levels of competition and lower price points.
There is another big factor – and that’s checkout. The company’s Shop Pay instant checkout converts at up to 50 per cent better than standard guest checkout, Shopify said in its release. With more than 100 million saved buyer profiles, Shop Pay is delivering a network effect that cannot be matched by any other e-commerce platform. For high-volume brands, even small conversion wins mean large revenue increases.
Shopify also benefits from the supply of agency and developer talent. A pool of experienced Shopify developers that’s 5-8X larger than BigCommerce – this means quicker hiring, more agency pricing options, wider access to specialised skills in areas like custom development, performance optimisation, and conversion rate improvement.
Planning the Migration
The good news is that when it comes to migrating from BigCommerce to Shopify, things do tend to get a bit smoother than with Magento. They’re both cloud applications, a SaaS with like-for-like data models, so the data replication exercise is made easier. Product catalogues, customer accounts and order history can usually be migrated with good tooling and easy-to-define mapping.
For an easy migration, I suggest you hire a BigCommerce to Shopify migration expert in agencies. In addition to the similar data models and functionality, there are also many nuances in product variants, customer groups, pricing rules and URL structures that need careful consideration from an expert user. For example, an agency that has completed tens of BigCommerce migrations will have templates and automation that remove a lot of project risk and timeline.
You’ll want to begin with an in-depth audit of your BigCommerce store. Write down everything that was customised, integrated and any features requiring Bigcommerce-only functionality. Any customisations of the stencil theme will need to be redone within Shopify’s Liquid templating language, and any API integrations that are custom will need to now leverage Shopify APIs. Knowing the total volume of work upfront will eliminate the scope creep that sabotages so many migration projects.
Data Migration and SEO Considerations
BigCommerce to Shopify product data migration is simple for the most part, but be mindful of variant types. BigCommerce has the capability to offer as many as 250 options per product, while Shopify’s maximum by default is 100 variants (this limitation can be easily circumvented with Combined Listings for larger brands).
URL redirect mapping is critical for preserving your organic search traffic. BigCommerce and Shopify use different URL patterns for products, categories, and content pages. Map every indexed URL and implement 301 redirects before your cutover date. A BigCommerce to Shopify Plus migration specialist will have templates and automation tools for this process, which can save weeks of manual work and reduce the risk of redirect errors.
Retain the entire SEO metadata in the course of migrating. Meta titles, descriptions, alt tags, structure data needs to be mapped and migrated in a programmatic manner. You should be especially diligent in staging to test your redirects and verify that they are working before going live with it. The stakes are large: a redirect migration gone wrong can set you months back in recovering organic traffic.
Post-Migration Optimization
Once live on Shopify, take advantage of platform-specific features that were not available on BigCommerce. Set up Shop Pay for accelerated checkout, implement Shopify Audiences for targeted advertising with better return on ad spend, and explore Shopify Markets for international expansion with localized currencies, languages, and domains.
Most brands see a conversion rate improvement of 10 to 25 percent within the first 90 days on Shopify, driven by faster page loads, Shop Pay’s accelerated checkout, and Shopify’s optimized purchase flow. Monitor your analytics closely during the first month to identify and address any issues quickly, and have your agency on standby for rapid response.
The BigCommerce to Shopify migration: As far as replatforming goes, it is one of the smoother in ecommerce. With careful planning, a seasoned implementation partner and rigorous testing most brands make the switch in 8-14 weeks without losing any time to market (and instead see meaningful increases in conversion performance).
The focus of integration testing is also unique and deserves special mention when migrating from BigCommerce to Shopify. Yes and no. They are both SaaS, they both have a similar API paradigm but the details of webhook payloads, order data structures and timing around inventory sync matter enough to actually cause issues if not flushed out by rigorous testing 😛 Prior to cutover, you will want to run end-to-end integration tests (peaking at least two full business cycles), with load testing simulating your busiest sales periods.
Change management is a common thing missing in the migration plan. Your customer service people, the marketing folks and the operations side of things, they all need to be trained on this new platform. Write thorough documentation for each team’s workflow; hold hands-on training sessions, and have a support channel for the first 30 days after moving, where people can get quick answers to questions. Brands that take change management seriously have smoother transitions, quicker recovery of team productivity, and fewer post-launch support tickets.
Choosing the Right Migration Partner
Some agencies are more experienced than others when it comes to migrating from BigCommerce to Shopify. Data mapping nuances, discrepancies in URL structure and reconfiguration of integrations all require particular expertise that most Shopify agencies don’t have. Ask your prospective agency partners how many BigCommerce Migrations they have done, ask for names of similar scale brands and understand their migration tooling and automation capabilities.
The most effective migration partners will provide comprehensive playbooks, automation tools and pre-built redirect mapping templates that minimise project risk and timeline. You should also look for a process around SEO preservation, including pre-migration audits, full-on planning of redirects and post-migration monitoring. When the cost of getting it wrong is months of traffic and sales lost, collaborating with proven experts is not a luxury.
