BigCommerce to Shopify Migration: The Complete Guide

BigCommerce and Shopify are both serious e-commerce platforms, and either can run a successful store. So when merchants ask about a BigCommerce to Shopify migration, the conversation isn't usually about one platform being broken — it's about fit. Where BigCommerce shines on built-in features and B2B functionality at lower tiers, Shopify wins on ecosystem depth, theme quality, app variety, and developer mindshare. Over time, those advantages compound into a meaningfully different operational experience.

This guide covers why merchants switch from BigCommerce to Shopify, what actually changes during the move, how to keep your SEO and revenue intact through the transition, and what the project realistically looks like in terms of cost and timeline.

Why merchants switch from BigCommerce to Shopify

The most common reasons we hear for moving BigCommerce to Shopify:

Ecosystem. Shopify's app store has roughly 8,000+ apps versus BigCommerce's 1,500-ish. For any given problem — subscriptions, reviews, loyalty, B2B, headless, ERP integration — Shopify almost always offers more options at higher quality. The same goes for themes: there are simply more good Shopify themes than BigCommerce ones.

Talent and agencies. Shopify is where the e-commerce industry's gravity is. Hiring a Shopify developer, agency, or freelancer is materially easier and cheaper than finding the equivalent BigCommerce talent. If your business depends on iterating on the storefront, that talent pool difference matters.

Checkout and conversion. Shopify's checkout, especially with Shop Pay, is among the highest-converting in the industry. Independent studies have consistently shown Shop Pay outperforms generic checkouts on conversion. BigCommerce's checkout is solid but doesn't have the same network effect.

SKU and revenue limits. BigCommerce's plans have hard revenue thresholds — cross them and you're forced into a higher tier whether or not you want the additional features. Shopify's pricing is more predictable as you scale (until Shopify Plus, which is a step up but a known one).

International selling. Shopify Markets makes multi-region, multi-currency, multi-language selling materially simpler than BigCommerce's equivalent setup.

What changes when you migrate from BigCommerce to Shopify

A BigCommerce to Shopify transfer is usually less painful than other platform migrations because both platforms are modern, hosted SaaS — but a few things shift:

• Categories become "collections." The taxonomy works similarly but the terminology and some behaviors differ. Smart collections (rule-based) are particularly powerful on Shopify.

• Custom fields become metafields. BigCommerce custom fields and Shopify metafields are conceptually similar but the data structure and editing experience differ. Mapping needs explicit planning.

• Product options handle differently. BigCommerce's product options/modifiers don't map 1:1 to Shopify variants. If you have complex configurable products, this is where most of the data work happens.

• URL structure changes. BigCommerce uses different URL patterns than Shopify, so the redirect map is essential to preserve SEO.

• Apps mostly have equivalents. The good news: nearly every BigCommerce app has a Shopify equivalent — usually with more competitors to choose from.

The migration process

The shape of a BigCommerce to Shopify migration:

1. Discovery and mapping. Audit your current BigCommerce setup — products, variants, customers, orders, content, apps, customizations, integrations. Map each piece to its Shopify equivalent or rebuild plan.

2. Shopify setup. Pick or build a theme, install the app stack, configure payments, shipping, and taxes.

3. Data migration. Products, variants, customers, and historical orders move across. BigCommerce data is generally clean and well-structured, which makes the migration smoother than coming from older or self-hosted platforms.

4. SEO preservation. Every BigCommerce URL gets a 301 to its Shopify equivalent. Title tags, meta descriptions, H1s, and image alt text carry over.

5. Theme and content build. Shopify themes are structured around Liquid and sections. If you've been using a BigCommerce Stencil theme, you're already comfortable with section-based theming — the concepts transfer.

6. Testing and launch. Full checkout testing, payment gateway verification, order flow validation, and DNS cutover.

For most BigCommerce merchants, the full migration runs 3–6 weeks. Stores with B2B portals, complex pricing rules, or heavy customization can extend to 8–12 weeks.

Data migration: the practical view

What moves cleanly from BigCommerce to Shopify:

• Products, including variants and option sets (with mapping work for complex options)

• Categories → collections

• Customer accounts (without passwords — same security limitation as every migration)

• Order history

• Pages and blog posts

• Most SEO metadata

What needs extra planning:

• Product reviews (typically migrated to a Shopify review app)

• Custom fields → metafields mapping

• Wishlists (depends on the BigCommerce app you used)

• B2B price lists (if you're moving to Shopify B2B on Plus, this needs explicit setup)

• Integrations with ERPs, 3PLs, and accounting tools — these need to be reconnected on the Shopify side

SEO during the move

The mechanical playbook is the same as any platform switch, and just as important:

• Complete URL map: every old URL → new URL

• 301 redirects live at launch

• Preserve titles, meta descriptions, H1s, alt text

• Submit the new sitemap to Search Console

• Monitor for 404s in the first month and fix anything that slipped through

Done properly, BigCommerce to Shopify migrations are among the cleanest from an SEO standpoint because both platforms have decent native SEO and the URL structures, while different, are predictable.

What it costs

A BigCommerce to Shopify migration with a standard catalog and clean data lands in the low-to-mid four figures (GBP) for most merchants. Larger catalogs, B2B requirements, or heavy customization push the project into mid-four or low-five figures. Our pricing page shows the full fixed-price packages so you know exactly where your project sits before we start.

Don't forget to factor in the Shopify subscription (£25–£289/month for standard plans, custom for Plus) and any apps you'll need ongoing.

Common pitfalls

The mistakes that derail BigCommerce to Shopify projects:

• Underestimating product option mapping. BigCommerce's option/modifier system is more flexible than Shopify variants in some ways. Stores with complex configurable products need this scoped carefully or they end up with products that don't display correctly post-launch.

• Not auditing apps before kickoff. Some BigCommerce apps don't have direct Shopify equivalents — usually it's specific niche tools. Better to find that out in week one than week six.

• Forgetting B2B logic. If you have wholesale customers, hidden pricing, or customer-group-specific catalogs on BigCommerce, that logic needs explicit rebuild on Shopify (often using Shopify B2B or a B2B app).

• Skimping on the redirect map. This is the universal migration killer. Don't.

Is the move worth it?

If you're happy on BigCommerce and the platform meets your needs, there's no urgent reason to switch. The honest case for a BigCommerce to Shopify migration is when you've hit one of these: you want a richer app ecosystem, your team is friction-blocked finding BigCommerce talent, you're scaling internationally, or your TCO has crept up enough that Shopify's economics now win.

FAQs

How long does a BigCommerce to Shopify migration take? Most projects complete in 3–6 weeks. Larger or more customized stores can take 8–12 weeks.

Will my SEO survive the switch? Yes, with proper planning. The redirect map and on-page SEO preservation are the deciding factors. Expect a small dip in weeks 2–4 followed by recovery.

Can I migrate my BigCommerce B2B setup to Shopify? Yes. If you're on Shopify Plus, Shopify's native B2B handles most use cases. Otherwise, B2B apps like BSS or Wholesale Gorilla replicate BigCommerce's wholesale features. The setup needs explicit planning during discovery.

What about my BigCommerce customer accounts? Customer records migrate; passwords don't (security limitation of every platform). Customers reset on first login.

Are Shopify and BigCommerce really that different in cost? At the lower tiers, BigCommerce often looks cheaper. Once you factor apps, hitting BigCommerce's revenue thresholds, and the time cost of working in a smaller ecosystem, Shopify usually evens out or wins on TCO over 2–3 years. The deciding factor is rarely the platform fee.

Can I keep my BigCommerce theme on Shopify? No. Themes are platform-specific. You'll either pick a Shopify theme (Dawn, Sense, and similar are excellent starting points) or have one custom-built. Most merchants use migration as a chance to refresh the design.

What happens to my abandoned cart emails and email flows? You'll rebuild them in your chosen email platform (Klaviyo, Omnisend, Shopify Email). Most flows are simple enough to recreate in a few hours; the work is more about reconnecting the data than rewriting the strategy.

Can I migrate from BigCommerce to Shopify myself? For very small stores, yes. For anything with meaningful revenue, the SEO redirect work and data edge cases are where DIY usually backfires. The cost of a botched migration is usually higher than the cost of a clean one.
