Migrating from BigCommerce to Shopify: A Merchant's Checklist for 2026

Deciding to replatform your ecommerce store is a major strategic move. For a growing number of merchants, the path leads from BigCommerce to Shopify, driven by the need for a more predictable cost structure, a larger app ecosystem, and faster operational speed. The switch is less about trend and more about gaining control over your technology stack and total cost of ownership.

While the benefits are clear, a successful migration hinges on careful planning and execution. A rushed process can lead to broken URLs, lost customer data, and a significant drop in search engine rankings. This checklist provides a reliable, step-by-step framework for moving your business from BigCommerce to Shopify in 2026, ensuring you arrive with your data, SEO equity, and customer base intact.

What are the main reasons merchants move from BigCommerce to Shopify?

Merchants migrate to Shopify primarily for its predictable pricing, extensive app ecosystem, and ease of use. Unlike BigCommerce, where sales growth can trigger automatic plan upgrades and higher fees, Shopify's pricing is more stable, making it easier to forecast expenses. The platform's vast app store also offers more flexibility to add functionality without custom development.

Many teams find Shopify's interface more intuitive for day-to-day tasks, allowing marketing and merchandising staff to make changes without needing developer support. This operational speed is a significant advantage. While BigCommerce offers strong built-in features, Shopify's model of a streamlined core platform extended by a rich ecosystem of apps often proves more scalable and adaptable for growing brands.

Finally, the total cost of ownership is a compelling factor. Shopify's structure often results in lower overall costs once app fees and potential developer expenses are factored in, especially for brands that value quick iteration and a wide selection of third-party integrations. The platform's focus on a user-friendly experience empowers store owners to manage more of their business themselves.

Consider the total cost of ownership with a real-world example. A store on the BigCommerce Pro plan hits $400,001 in annual sales, just over the plan’s limit. It is automatically upgraded to the next tier or forced to pay overage fees, and its monthly cost can jump significantly from around $300 to a much higher, negotiated Enterprise rate. This is a sudden and often unplanned expense.

Now compare this to Shopify Plus, which starts at a higher base fee of around $2,500 per month but scales more predictably. For a store with high volume, the platform fee may become a small percentage of revenue, such as 0.40% on a one-year term. While app costs add to this, the pricing scales smoothly with growth. There are no sudden cliffs or forced upgrades based on revenue thresholds.

This predictability is the key difference. A Shopify merchant can forecast their costs with much greater accuracy, even with a growing app stack. For a BigCommerce merchant, crossing a sales threshold can feel like a penalty for success. This makes financial planning difficult and incentivizes looking for a platform with a more transparent cost structure.

Which data (products, customers, orders) can be migrated automatically?

Core store data like products, customers, and order history can be migrated from BigCommerce, but the process is rarely fully automatic. Migration is typically handled using third-party apps like Matrixify, LitExtension, or Commerce Hop, which connect the two platforms and map the data fields. These tools can transfer product details, customer records, and basic order information.

You can also export data from BigCommerce as CSV files and import it into Shopify, but this requires careful formatting. While product and customer data can be moved this way, Shopify's native tools do not support importing order history via CSV. This makes a dedicated migration app the more common choice for preserving historical sales data.

It's crucial to understand what doesn't migrate. Key items like customer passwords, store credit, and gift card balances cannot be transferred directly for security and technical reasons. Your BigCommerce theme and many app-specific settings will also need to be rebuilt or reconfigured from scratch on Shopify.

How to Handle Data That Won't Migrate

Gift cards are a common stumbling block. Because they represent a cash liability, they cannot be transferred between platforms. The balance exists only within BigCommerce's system. Failing to migrate these balances means customers lose their money, leading to support tickets and lost trust. The financial cost is a direct write-off of that outstanding value.

The solution is a manual but necessary process. Before migrating, export a full list of all active gift cards and their remaining balances from BigCommerce. After launching on Shopify, you must manually recreate each one using Shopify’s native gift card feature or a migration app. This is a concrete task your team must plan for and execute post-launch.

How do you handle URL redirects to protect your search engine rankings?

You must create a 301 redirect for every BigCommerce URL that is changing to preserve your SEO. BigCommerce and Shopify use different URL structures; for example, Shopify uses fixed paths like `/products/` and `/collections/`. This means every single one of your old URLs will break after migration unless you map it to its new Shopify equivalent.

The process involves three main steps. First, crawl your entire BigCommerce site to export a complete list of all current URLs. Second, create a two-column spreadsheet mapping each old URL to its corresponding new URL on your Shopify development store. Finally, import this redirect map into Shopify using its built-in URL Redirects tool, which accepts a CSV upload.

Prioritize your most valuable pages by pulling traffic data from Google Search Console. While migration apps can generate some redirects automatically, it is essential to manually review the map for your top-performing pages. Neglecting this step is one of the fastest ways to lose organic traffic and search rankings during a platform switch.

An edge case that breaks this process is faceted navigation URLs. BigCommerce often creates URLs with parameters for filtered results, like `?brand=acme&color=blue`. These URLs can attract valuable, long-tail organic traffic. Shopify's default collection filtering does not create crawlable URLs in the same way, so there is no direct equivalent to redirect to.

This introduces a trade-off called "ranking signal consolidation." You cannot preserve the specific ranking for every filtered view. Best practice is to redirect these parameterized URLs to the main parent collection URL. This consolidates all SEO equity into the primary page, which is better than having hundreds of 404 errors, but the revenue from some long-tail rankings may be lost.

How do you find Shopify apps to replace BigCommerce's built-in features?

Start by conducting an audit of your current BigCommerce store. Make a comprehensive list of every built-in feature and third-party app your business relies on. For each item, define its core function, such as "product reviews" or "subscription billing." This list becomes your shopping list for the Shopify App Store.

BigCommerce includes more functionality out-of-the-box, so features you took for granted may require an app on Shopify. For example, advanced product filtering, which is native in some BigCommerce plans, is handled by Shopify's Search & Discovery app or other third-party solutions. Similarly, product reviews and loyalty programs are managed through apps like Judge.me or Loox.

With over 8,000 options, the Shopify App Store almost certainly has a solution. Search the store using the core functions you identified. Pay close attention to app reviews, update frequency, and support quality. This is an opportunity not just to replace functionality but to upgrade it. Many merchants find that Shopify's specialized apps offer more powerful features than BigCommerce's all-in-one approach.

Budgeting for Your New App Stack

This transition from built-in features to a curated app stack has direct budget implications. For example, BigCommerce's "Customer Groups" feature for segmenting shoppers is included in Plus and Pro plans. On Shopify, achieving similar functionality for wholesale or VIP tiers may require a dedicated app like Wholesale Gorilla, which can cost around $40 per month.

Similarly, features like product file uploads or custom fields, often native to BigCommerce, require Shopify apps to replicate. While many excellent apps are free or low-cost, a typical mid-market store should budget between $200 to $500 per month for their app stack. This cost is a crucial part of calculating your new total cost of ownership.

What is the best way to migrate customer passwords?

You cannot migrate customer passwords from BigCommerce to Shopify. For security reasons, passwords are encrypted and cannot be exported from one platform and imported into another. Every migration project, regardless of the platforms involved, faces this same constraint. Your customers will need to create a new password for their account on your new Shopify store.

The best approach is proactive communication. Before the migration, inform your customers that you are moving to a new platform and that they will need to reactivate their accounts. After you go live on Shopify, you can use an app like the Bulk Account Inviter to send an email to all imported customers, prompting them to create a new password.

Frame this as a security enhancement. You can also place a prominent banner on your new store's login page for the first few weeks, guiding returning customers through the quick process of resetting their password. While a minor inconvenience for shoppers, it is a standard and necessary step in protecting their data during a platform change.

Choosing your platform is about more than features; it's about choosing your operational model. A smooth migration sets the stage, but the real win is the speed and flexibility you gain afterward to run and grow your business.

How should you plan your migration to minimize downtime?

Minimizing downtime requires building your new Shopify store in parallel, not sequentially. While your BigCommerce store remains live, you should be setting up your Shopify theme, configuring apps, and migrating data to a development store. This allows for thorough testing before you ever point your domain to the new site.

A critical step is to implement a "content freeze" on your BigCommerce store about a week before your planned launch date. This means no new products, price changes, or content edits. This ensures the data you migrate is the final version, preventing inconsistencies. Your final data export and import should happen during this freeze period.

Plan the final cutover for a low-traffic period, like late at night or on a weekend. The cutover itself involves updating your DNS records to point your domain to Shopify's servers. Once live, perform a final round of testing on the live site, checking critical paths like checkout, key landing pages, and contact forms.

What are the most common issues faced during a BigCommerce to Shopify migration?

The most common issue is a loss of search engine ranking due to an incomplete or incorrect URL redirect strategy. Another frequent blocker involves product variants. BigCommerce allows more product options than Shopify's native limit of three, which can force merchants to restructure complex products. This requires careful planning before data is moved.

This product variant limitation is a hard wall for many merchants. For example, a furniture store selling a sofa with four options, fabric, color, leg style, and cushion firmness, cannot create this as a single product in Shopify. A migration tool will either fail on this product or strip the fourth option, creating inaccurate data.

The most common workaround is to split the product. The sofa might become two separate products: "Fabric Sofas" and "Leather Sofas." This keeps you within the three-option limit but complicates inventory management and can confuse customers. It is a concrete structural change you must decide on before migration even begins.

Alternatively, apps like Bold Product Options can bypass the limit by using line item properties instead of variants. However, this introduces a trade-off. These custom options may not be compatible with all third-party systems, such as a warehouse management system or an ERP, which expect standard Shopify variant data. This can create downstream fulfillment errors.

Data mapping is another trouble spot. Custom fields in BigCommerce do not have a direct equivalent in Shopify and must be mapped to metafields, which can be a manual and complex process. Furthermore, merchants often underestimate the work required to find and configure Shopify apps to replace BigCommerce's native features.

Finally, customer account issues are common. Because passwords cannot be migrated, there is often confusion if the process isn't communicated clearly to customers before launch. A lack of thorough testing is the umbrella over all these issues; rushing to launch without checking every critical function on the new site is the leading cause of post-migration problems.

What steps should you take immediately after your Shopify store goes live?

The first step is to submit your new `sitemap.xml` file to Google Search Console. This prompts Google to crawl and index your new URLs. For the next several days, closely monitor the Coverage report in Search Console for any new crawl errors, such as 404 "not found" pages, and fix them immediately.

Next, place test orders to ensure your entire checkout process, payment gateways, tax settings, and shipping rules are functioning correctly. Send a welcome email to your customers announcing the new site and guiding them on how to activate their accounts. It is also wise to monitor customer feedback channels for any unreported issues with the user experience.

Once your new store is stable, it's time to optimize your operations. A common challenge for growing stores is managing multiple orders from the same customer, which increases shipping costs and complicates fulfillment. You can use an app like Tacey to merge orders from a single customer before they are shipped. This simplifies your workflow and saves money, starting your journey on the new platform with a more efficient process. Explore Tacey on the Shopify App Store to see how it streamlines post-purchase operations.

Frequently asked questions

Can I migrate my BigCommerce theme to Shopify?

No, you cannot directly migrate a BigCommerce theme to Shopify. The two platforms use entirely different templating languages and structures. You will need to select a new theme from the Shopify Theme Store or work with a developer to build a custom theme that matches your previous design.

How long does a BigCommerce to Shopify migration take?

A typical migration takes between 6 to 10 weeks from start to finish. This timeline includes data auditing, theme development, data migration, app configuration, and thorough testing. Simple stores with small catalogs might move faster, while stores with complex data or custom integrations can take longer.

Do I need a developer to migrate from BigCommerce to Shopify?

Not necessarily, but it is often recommended. While migration apps have made the process more accessible, a developer or agency can manage the technical complexities of data mapping, SEO preservation, and custom theme development. For stores with complex catalogs or custom features, professional help significantly reduces the risk of costly errors.

What happens to my BigCommerce store after migration?

You should keep your BigCommerce store active for a short period after launching on Shopify as a backup. Once you are confident that your Shopify store is stable and all data is correct, you can cancel your BigCommerce plan. Be aware that BigCommerce will permanently delete your store data 30 days after cancellation.

Will I lose sales during the migration?

If planned correctly, you should experience minimal to no loss of sales. The migration strategy involves building and testing your new Shopify store in the background while your BigCommerce store continues to operate. The only actual downtime is the brief period when your domain's DNS is updated to point to Shopify, which typically takes a few hours at most.
