BigCommerce to Shopify, platform parity audited first.
Stencil to Liquid, multi-storefront to Shopify Markets, checkout to Shopify Payments. A replatform with no ecosystem regression and a shorter timeline than any Magento or Woo cutover.
Feature parity, audited line by line.
BigCommerce and Shopify are the closest major platforms on a capability map. They both run a hosted commerce engine, both expose a Storefront API, both have headless options, both host a payment relationship. The question on a BigCommerce migration is not "can Shopify do this" (almost always yes) but "where does Shopify do this differently, and what rebuilds in the cutover?" The table below is the line-by-line parity audit we run in week one of every engagement.
| Capability | BigCommerce | Shopify |
|---|---|---|
| Theme engine | Stencil (Handlebars) | Liquid + Sections / Blocks |
| Headless option | BigCommerce Catalyst | Shopify Hydrogen + Oxygen |
| App ecosystem | ~1,000 apps | ~8,000 apps |
| Payment gateway | External (Stripe, PayPal, Braintree) | Shopify Payments (on Stripe) or external |
| Multi-storefront | BigCommerce Multi-Storefront (Enterprise) | Shopify Markets (Plus) |
| B2B | Price lists + customer groups | Native Plus B2B (Companies, catalogs) |
| Checkout customization | Stencil override + Optimized Checkout SDK | Checkout UI Extensions + Functions (Plus) |
| Cart + catalog rules | Product rules + price lists | Variants + metafields + Functions |
| CMS / content | Web pages + page builder | Pages + metaobjects + Sections |
| SEO primitives | Native + some plugin help | Native + schema.org JSON-LD |
| Partner + agency network | Smaller | Shopify Partners (much larger) |
| Release cadence | Quarterly-ish | Weekly via changelog |
The table reads as incremental differences, but each row compounds. A single 90-day project on Shopify can touch four or five rows where the Shopify side has deeper support: that is where the productivity delta comes from. The audit names which rows matter most for your specific configuration.
Seven primitives. All migrate.
Products + variants
BigCommerce products and options become Shopify products with variants. Rules translate to Cart Transform Functions where needed.
Categories
Become Shopify Collections. Navigation menus rebuild to match the new handle structure.
Customers
Email, name, addresses, consent preserved. Password reset via one-time email on cutover.
Orders (read-only)
Historical orders imported for customer service lookup via the Shopify Admin API.
Customer groups
Become Shopify customer segments. On Plus, B2B groups map to native Company accounts.
Content + blog
Web pages become Pages, blog posts keep permalinks via the 301 map.
Two platforms. One tipping point.
Handlebars out. Liquid in.
BigCommerce Stencil uses Handlebars templating with a JavaScript build pipeline. Shopify Liquid is server-rendered with Section and Block composition. The translation below is the pattern-level map every Stencil theme rebuilds against.
| Stencil concept | Shopify Liquid equivalent | Notes |
|---|---|---|
| {{#each}} | {% for %} | Direct equivalent. |
| {{#if}} | {% if %} | Direct equivalent. |
| page_builder (sections) | Shopify Sections + Blocks | Model is cleaner on Shopify. |
| Stencil CLI bundle | Shopify CLI (local dev) | Similar workflow, better tooling. |
| Theme settings schema | settings_schema.json | Different JSON shape, same intent. |
| Global resource includes | snippets/ + render tag | Shopify has cleaner partial loading. |
| Stencil-utils JS | Section Rendering API + Theme JS | Shopify ships more native helpers. |
Optimized Checkout out. Shopify checkout in.
BigCommerce Optimized Checkout with JavaScript overrides translates to Shopify's extensibility surfaces on Plus. Payment rails change: BigCommerce uses external gateways, Shopify Payments is native. Both are well-documented migration paths; neither is the risky part of the project.
BigCommerce Optimized → Shopify UI Extensions
JavaScript overrides on BigCommerce Optimized Checkout map to Shopify Checkout UI Extensions on Plus. Fields, compliance copy, upsell, one-click post-purchase, all supported natively.
Stripe / PayPal / Braintree → Shopify Payments
Stripe and PayPal carry cleanly either as native Shopify Payments (on Stripe) or as third-party gateway on Shopify. Recurring tokens typically migrate via Stripe account-to-account flow.
BC Fraud Protection → Shopify Fraud Analysis
Shopify ships fraud analysis native plus deeper integration with Stripe Radar. Custom fraud rules migrate to Shopify Flow automations.
BC Tax → Shopify Tax + Avalara
Tax rules migrate to Shopify Tax or Avalara AvaTax for multi-state complexity. Exemption certificates transfer via CSV.
Every indexed URL. Mapped.
BigCommerce URLs follow a different pattern to Shopify: /products/{slug}/ rather than /products/{handle}, /categories/{slug} rather than /collections/{handle}. The 301 map translates every pattern, every indexed URL, every canonical.
- Pre-migration crawl: Screaming Frog plus Google Search Console export to inventory every indexed URL.
- Backlink audit: Ahrefs or SEMrush export; every URL with external backlinks prioritised by domain rating.
- 301 map CSV: every BigCommerce URL paired with its Shopify equivalent, loaded via Shopify URL Redirects.
- Canonical + hreflang: preserved verbatim from source, never regenerated.
- Structured data: Product, BreadcrumbList, Organization JSON-LD per schema.org migrated to Shopify theme.
- Search Console change of address: filed immediately after DNS flip per Google's migration guidance.
- Daily crawl monitoring: 60 days post-cutover. Any 404 triggers immediate redirect entry.
Many stores. One catalogue.
BigCommerce Multi-Storefront runs separate storefronts with duplicated catalogues and inventory sync headaches. Shopify Markets keeps one catalogue plus per-market pricing, currency, language, domain, and payment method. The consolidation alone usually justifies the migration.
| Shape | BigCommerce | Shopify Plus |
|---|---|---|
| Catalog | Duplicated per storefront | One catalog, per-market price overrides |
| Inventory | Synced via third-party app | Shared pool with per-location allocation |
| Currency | Per-storefront config | Markets native, auto-conversion via Markets pricing rules |
| Language | Per-storefront translation | Markets + Translate & Adapt |
| Domain | Separate per storefront | Subfolder, subdomain, or separate domain per market |
| Admin | Separate BigCommerce admin | Single Shopify admin, market filter |
| Annual platform cost | Per-storefront licensing | One Plus plan covers all markets |
Four BC storefronts. One Shopify Plus. 13 weeks.
An archetype outdoor-gear brand with $6.4M annual revenue across four BigCommerce Enterprise storefronts (US, UK, EU, AU), ~1,800 SKUs each storefront (mostly duplicated), and an annual renewal that had drifted into six figures. The ask: consolidate to Shopify Plus with Markets, preserve SEO across every domain, keep Cloudflare DNS architecture intact.
What shipped: 1,824 unique SKUs on one catalogue (previously ~7,300 duplicated across four storefronts), 4 Markets (US, UK, EU, AU) with per-market pricing + currency + domain, 3,100-URL 301 map aggregated from all four source domains, Klaviyo consolidated from 4 accounts to 1 with suppression lists merged, Stripe accounts restructured for Shopify Payments per region. Post-cutover monitoring: rankings stable from day 6, organic traffic up 8% at day 60.
Six questions BigCommerce merchants ask.
How long does a BigCommerce to Shopify migration take?
A standard BigCommerce to Shopify migration runs 10 to 12 weeks for catalogs under 5,000 SKUs on a single storefront. BigCommerce Enterprise merchants migrating to Shopify Plus with multi-storefront consolidation or B2B requirements run 14 to 18 weeks. BigCommerce migrations are typically 2 to 4 weeks faster than Magento or WooCommerce migrations because the data models are similar enough that the schema translation layer is lighter.
Why migrate from BigCommerce to Shopify when the platforms are similar?
Three reasons dominate in our BigCommerce migration audits. First, ecosystem depth: Shopify App Store has about 8,000 apps, BigCommerce has a much smaller catalogue, and apps you need often do not exist on BigCommerce. Second, feature velocity: Shopify ships weekly, BigCommerce ships slower, so over 24 months the gap widens. Third, payment consolidation: Shopify Payments rolls processing and platform into one relationship, whereas BigCommerce requires a separate payment gateway with its own contract and fee structure.
Can we consolidate multiple BigCommerce storefronts into one Shopify store?
Yes, usually via Shopify Markets on Shopify Plus. BigCommerce Enterprise multi-storefront often runs as separate stores with duplicated catalogues; Shopify Markets keeps one catalogue plus per-market pricing, currency, language, and domain. The consolidation alone typically cuts annual platform cost by 30 to 50 percent and removes inventory sync headaches. For use cases that Markets cannot express (truly distinct catalogues per brand), we build separate Shopify stores with shared back-office via API.
What happens to our Stencil theme?
Stencil themes do not port. BigCommerce Stencil uses Handlebars templating; Shopify uses Liquid. We rebuild the front end on either a Shopify Dawn-derivative theme (for most merchants) or Shopify Hydrogen (for headless React requirements). The rebuild is not purely cost: it is a chance to adopt Shopify's Section and Block model, which editors prefer to Stencil's page builder for day-to-day merchandising work.
How does payment processing compare between BigCommerce and Shopify?
BigCommerce partners with external gateways (Stripe, PayPal, Braintree, and others) and does not charge a platform transaction fee on top. Shopify Payments uses Stripe under the hood but rolls processing plus platform into one relationship with lower friction. If you are on Shopify Payments, Shopify charges zero additional platform fee; on third-party gateways, Shopify charges a small percentage in addition to the gateway fee. For most US merchants, consolidating to Shopify Payments is neutral to slightly positive on total cost, with the operational simplicity a net win.
Will we lose SEO rankings during the cutover?
Only if the migration is engineered poorly. We ship three safeguards on every migration: every indexed BigCommerce URL gets a 301 redirect to its Shopify equivalent before DNS flips; canonical tags, hreflang, and structured data are preserved or improved on Shopify; and a Google Search Console migration is filed immediately after cutover. With those in place, ranking recovery is typically full within 14 to 30 days. Blog content often benefits from the move because Shopify pages tend to render faster than equivalent BigCommerce pages on mobile.
