Shopify PartnerBigCommerce to Shopify Migration Service
We migrate BigCommerce catalogue, customer, order, content, B2B, integration, and SEO requirements into a Shopify store ready for controlled launch.
What migrates from BigCommerce to Shopify
Both platforms are hosted, but their data models differ. This is how the main BigCommerce records usually map to Shopify; we confirm the details for your store during the assessment.
Products and variants
YesProducts, SKUs, prices, stock and images migrate. BigCommerce options and modifiers are mapped to Shopify variants, line-item properties or metafields, and catalogues are checked against Shopify's variant and option limits.
URLs and 301 redirects
YesBigCommerce URLs are mapped to Shopify's /products/, /collections/, /pages/ and /blogs/ patterns with permanent redirects.
SEO metadata
YesPage titles and meta descriptions move to Shopify's SEO fields.
Customers
YesProfiles and addresses migrate.
Order history
YesHistorical orders are imported and linked to customers without triggering emails, payments or stock changes.
Categories and brands
YesCategories become collections; brands move to the vendor field, collections or metaobjects.
Reviews
Yes, via a review appBigCommerce product reviews are exported and imported into your chosen Shopify review app.
Blog posts and web pages
YesContent moves to Shopify blogs and pages, with layouts rebuilt in the theme.
Custom fields
Yes, with mappingProduct custom fields move to Shopify metafields.
Customer groups and price lists
Yes, with mappingDepending on the requirement they become Shopify B2B companies and catalogues, customer tags with discounts, or app-based pricing.
Subscriptions
DependsSubscriptions run through an app on both platforms, so the approach depends on the app and payment gateway in use.
Gift certificates
PartlyBalances are recreated as Shopify gift cards; codes may need to be re-issued.
Store credit
Yes, after reconciliationBalances are recreated as Shopify store credit.
Coupons and promotions
RecreatedCoupon codes and promotion rules are rebuilt as Shopify discounts.
BigCommerce and Shopify differ in the details that matter
Product options, modifiers, customer groups, price lists, channels, scripts, and integration ownership need a defined target rather than a direct field copy.
Moving between managed platforms is still a replatform, not a theme swap. We focus discovery on the BigCommerce features and integrations that affect revenue, operations, customer experience, and reporting.

Our BigCommerce to Shopify migration process
- 1.
Feature and data inventory
We document the catalogue, customers, orders, content, channels, scripts, apps, APIs, B2B needs, and operational workflows.
- 2.
Shopify target mapping
Every important BigCommerce structure and workflow is assigned to a Shopify feature, app, extension, integration, or retirement decision.
- 3.
Test imports and reconciliation
Representative data is transformed and checked for counts, relationships, prices, inventory, accounts, orders, content, and exceptions.
- 4.
Storefront and stack rebuild
We deliver the Shopify storefront, configuration, apps, extensions, tracking, and integrations required to trade.
- 5.
UAT and cutover rehearsal
Customer journeys, B2B workflows, operations, SEO, analytics, and the final sync sequence are validated with named owners.
- 6.
Launch and monitoring
The final delta, DNS, redirects, feeds, tracking, integrations, and support coverage are coordinated and monitored.
Migration risk assessment
What we review before your BigCommerce migration
We compare the live BigCommerce implementation with the proposed Shopify setup and expose the gaps before delivery starts.
Customer and B2B needs
Groups, companies, price lists, accounts, quotes, terms, taxes, and order history are assessed.
Storefront and stack
Scripts, apps, channels, APIs, integrations, analytics, feeds, and operational tools are documented.
You receive a scoped migration approach, major risks, dependencies, and the decisions needed before implementation.

Migration apps vs a managed migration
Apps such as Cart2Cart and LitExtension connect to BigCommerce and copy common records into Shopify, while import tools such as Matrixify load prepared spreadsheets. For a straightforward catalogue they are a quick, cost-effective way to move data.
When a migration app is usually enough
- A modest catalogue with simple products and variants
- Few integrations, apps or custom fields to carry over
- Limited organic traffic, so redirects can be handled with a short list
- An in-house team with time to check the imported data and fix exceptions
When a managed migration is worth it
- Organic search matters and every indexable URL needs a mapped redirect
- Custom fields, complex options, B2B pricing or subscriptions need deliberate mapping
- ERP, fulfilment, marketing or other integrations must keep working on day one
- You need record-level reconciliation, rehearsal imports and a planned cutover
A managed migration can still use these tools where they fit. The difference is that one team owns the result, from mapping to launch.
BigCommerce to Shopify migration FAQ
A BigCommerce to Shopify migration typically takes 4–6 weeks depending on catalogue size, integrations and design scope.
We confirm the timeline after the risk assessment, once data volumes, integrations and the storefront scope are clear.
It depends on scope: the size and complexity of the catalogue, which data needs to move, the integrations and custom functionality involved, and whether the storefront is being redesigned or rebuilt.
We don't quote a figure before we've seen the store. The risk assessment comes first and gives you a scoped approach to price against.
No. Your BigCommerce store stays live and keeps trading while we build and test the Shopify store separately. Any short content or order freeze is agreed with you in advance.
We crawl indexable product, category, brand, and content URLs, preserve useful content and metadata, map permanent redirects, validate canonicals and internal links, and monitor indexing after launch.
Customer passwords can't be transferred because they are stored as one-way hashes, so customers activate their Shopify accounts or sign in with a one-time code.
Anything else that can't move directly is documented with a replacement plan rather than silently dropped.
