BigCommerce to Shopify Migration

BigCommerce merchants migrate to Shopify for a consistent set of reasons. A bigger app ecosystem. More designers and developers fluent in the platform. Pricing that doesn’t penalize growth. Plus a community that talks publicly about what’s working, which makes everything easier when you have a question.

The migration is straightforward in principle and tricky in execution. Some BigCommerce concepts (product modifiers, price lists, customer groups) don’t map directly to Shopify equivalents. The redirect map needs careful planning because BigCommerce URL structures aren’t identical to Shopify’s. Plus your existing apps probably have different Shopify equivalents that need evaluation.

What We Migrate

• Products. Title, description, options translated to variants, modifiers translated to the right Shopify pattern, images, custom fields, plus SEO metadata.
• Customers. All accounts migrated. Passwords reset on first login via Shopify’s standard flow.
• Orders. Full history available in the Shopify admin.
• Categories. Mapped to Shopify collections.
• B2B price lists and customer groups. Mapped to native Shopify B2B (on Plus) or to apps (on standard).
• Blog content. Posts, authors, images, categories.
• Redirects. Every indexed URL gets a 301 to the new Shopify equivalent.
• SEO metadata. Titles, descriptions, canonicals, structured data.

Why Brands Choose Us for BigCommerce Migrations

Platform-specific experience. BigCommerce migrations involve different patterns than WooCommerce or Magento. Product options, modifiers, the API differences. We know the patterns and we know which BigCommerce features need a Shopify equivalent that doesn’t exist by default.

Theme built during migration. Default Shopify themes are fine. Custom themes built for your brand convert better. We do the design and development as part of the migration, not as a follow-on project six months later.

Full post-launch coverage. Edge cases show up in the first 30 days after launch. Customers with old saved URLs, third-party integrations pointing at the old domain, plus oddball product data that didn’t show up in QA. We monitor and fix as it surfaces.

Mapping BigCommerce Features to Shopify

BigCommerce and Shopify look similar from the admin, but a few core concepts don’t have a one-to-one equivalent. These are the ones that decide how clean your migration is:

• Modifiers. BigCommerce modifiers (text fields, dropdowns, file uploads that customize a product without creating a new SKU) have no native Shopify concept. We map them to line item properties for typed input, or to a product-options app for dropdowns and uploads, or convert them to variants where they genuinely change price and inventory. Skipping this step means orders arrive missing their customization data.
• Variant limits. Shopify caps products at three option types and 100 variants on most plans, expandable to 2,000 on Plus. BigCommerce has no hard cap, so any product exceeding those limits gets restructured before import, usually by combining options or splitting into a combined listing.
• Categories and brand pages. BigCommerce categories are a hierarchy and brand pages are a native content type. Shopify collections are flat and have no brand concept. We rebuild the hierarchy through navigation and collection structure, and give brand pages a dedicated plan because they often pull long-tail organic traffic you don’t want to lose.
• B2B price lists and customer groups. These map to native Shopify B2B on Plus, where companies and locations replace customer groups, or to a wholesale app on standard Shopify. Either way the pricing rules carry over.
• Multi-Storefront. One BigCommerce account running several storefronts maps to Shopify Markets for regional variations of one brand, or to Plus expansion stores for genuinely distinct catalogs. We settle which during the audit, because it drives your tier and app stack.

Anything without a clean equivalent becomes a small custom app or Shopify Function rather than a compromise, and you get the full map before kickoff.

Migration Timeline

Most of the variability comes from three things: restructuring products that exceed Shopify’s variant limits, re-modeling B2B if you run BigCommerce B2B Edition, plus integrations with external systems like ERP or 3PL.

How Much Does a BigCommerce to Shopify Migration Cost?

Two numbers get confused, so separate them. The first is the Shopify plan you pay Shopify each month, which for many BigCommerce merchants comes in lower than the Pro or Enterprise tier they were on, especially since Shopify’s pricing doesn’t climb with revenue the same way. The second is the migration project, paid to us once.

Project cost is driven by catalog size, B2B price-list complexity, plus how many modifiers and custom fields need rebuilding on the Shopify side. A clean catalog with a custom theme sits at the lower end; a large B2B store with Multi-Storefront sits higher. The custom theme is built into the project rather than billed separately. We give you a fixed scope after the audit, so the number you approve is the number you pay.

What We Don’t Promise

We don’t promise zero traffic movement. Some short-term volatility is normal while Google reprocesses the redirect map. What we do promise is the architecture that makes a clean recovery: complete 301s built from what’s actually indexed, preserved metadata, structured data carried over, plus performance that’s typically better on Shopify. That’s what gets rankings back, usually within two to four weeks.

We also don’t rely on a migration app alone. Off-the-shelf tools move data but skip the redirect map, the theme, plus the B2B re-modeling. They’re a starting point, not the whole job.
