BigCommerce to Shopify: The Complete Migration Playbook
BigCommerce is powerful, but Shopify Plus offers better economics, faster innovation, and a cleaner path to enterprise scale. Ruby Digital Agency specializes in moving established stores without the drama, data loss, or downtime.
Why BigCommerce Stores Are Migrating to Shopify
BigCommerce is feature-rich and designed for mid-market retailers, but it comes with complexity and costs that don't scale efficiently. Shopify and Shopify Plus offer simpler operations, faster innovation cycles, and lower total cost of ownership—without sacrificing capabilities.
Faster, Better Conversions
Shopify's checkout is optimized for conversion at scale. Brands migrating from BigCommerce see 10–16% faster page loads and 8–14% conversion rate improvements within 90 days.
Significantly Lower Costs
BigCommerce's per-transaction fees and hosting costs add up quickly. Shopify's predictable, all-inclusive pricing model saves mid-market retailers 30–45% annually on platform and infrastructure expenses.
Best-in-Class App Ecosystem
BigCommerce's app marketplace is limited compared to Shopify's 8,000+ vetted integrations. Marketing, fulfillment, analytics, and subscription apps are plug-and-play on Shopify.
Enterprise Scale Without Complexity
Shopify Plus handles multi-store, multi-region, and high-volume operations effortlessly. No server management, no infrastructure scaling headaches—just reliable growth.
Faster Feature Delivery
Shopify ships improvements monthly. New payment methods, advanced analytics, and AI-powered features roll out automatically. BigCommerce's release cycle is slower and often requires custom work.
Modern Developer Experience
Shopify's Liquid templating and GraphQL APIs are modern and well-documented. BigCommerce's development model is more fragmented, making custom work slower and more expensive.
The Real Challenges: What BigCommerce Store Owners Face During Migration
📊 Data Migration Complexity
| Challenge | Why It Matters | How RDA Solves It |
| Product catalog structure mismatch | BigCommerce uses a different product taxonomy (categories, brands, custom fields) than Shopify. Direct export/import often loses custom fields, brand hierarchies, or advanced metafields. | RDA maps BigCommerce's entire product structure to Shopify's data model using custom transformation scripts. All custom fields, brands, and hierarchies are preserved or migrated to Shopify metafields. |
| Complex variant & modifier handling | BigCommerce's modifiers (options that affect price/weight/sku) differ from Shopify's variant model. Migrating complex SKU logic often results in pricing errors or duplicate variants. | RDA audits all variant logic, recreates modifiers as Shopify variants or metafields, and tests pricing, weight calculations, and SKUs against 100% of product options before launch. |
| Customer account & password transfer | BigCommerce and Shopify use different password hashing algorithms. Customers cannot log in immediately after migration—leading to frustration and support tickets. | RDA sets up automated, personalized password reset flows with clear instructions. Customers reset passwords within 24 hours. RDA monitors support channels during the critical first week. |
| Order history with abandoned carts | BigCommerce tracks abandoned carts differently than Shopify. Migrating cart history cleanly (especially for recovery workflows) is tricky and often skipped, losing valuable customer data. | RDA migrates all orders with full detail and audit trails. Abandoned carts are preserved as draft orders or imported into your email marketing platform for targeted recovery campaigns. |
| Asset URL & image migration | BigCommerce images and assets often live on the BigCommerce CDN. After migration, links break unless repointed to Shopify. Result: broken product images, reduced conversions, SEO penalties. | RDA downloads all assets from BigCommerce, uploads to Shopify's CDN, rewrites all URLs in product descriptions and content, and verifies 100% rendering before go-live. |
🎨 Frontend, Theme & UX Issues
| Challenge | Why It Matters | How RDA Solves It |
| Handlebars template conversion | BigCommerce themes use Handlebars templating. Shopify uses Liquid. You can't simply port BigCommerce themes—the syntax is completely different, and all logic needs to be rewritten. | RDA audits your BigCommerce theme, extracts design patterns and functionality, and rebuilds everything using Shopify's Liquid language. Your brand and UX remain intact. |
| BigCommerce app dependencies | BigCommerce apps (product filters, wishlists, reviews, payment apps) don't exist on Shopify in the same form. Missing features create a degraded customer experience post-migration. | RDA maps each BigCommerce app to Shopify equivalents (or custom solutions), tests all workflows, and ensures feature parity or identifies superior alternatives before launch. |
| API-based customizations | BigCommerce's REST and GraphQL APIs may have been used for custom integrations. These integrations won't work on Shopify without porting to Shopify's API architecture. | RDA documents all custom API logic, recreates it using Shopify's GraphQL and REST APIs, and ensures all custom workflows function identically on the new platform. |
| URL structure & SEO preservation | BigCommerce URLs (e.g., `/store/products/123-productname`) differ from Shopify's structure (`/products/productname`). Without 301 redirects, you lose 40%+ organic traffic and get search penalties. | RDA creates a complete URL map and implements 301 redirects for every product, category, and page. Your organic traffic flows seamlessly to Shopify with full SEO equity preserved. |
| Search engine crawl & indexing | Poor migration prep leads to crawl errors, duplicate content, and indexing delays. Google re-crawls and may penalize your rankings during the transition. | RDA audits all meta tags, implements proper canonicals, submits updated XML sitemaps, and actively manages the migration crawl through Google Search Console to protect rankings. |
🔌 Integration & Functionality Issues
| Challenge | Why It Matters | How RDA Solves It |
| Payment gateway reconfiguration | BigCommerce integrates with certain payment processors differently than Shopify. Moving payment connections often requires re-setup with new API keys and merchant accounts. | RDA tests all payment methods (Stripe, PayPal, Authorize.Net, Square, etc.) in staging. Reconfigures processors for Shopify. Zero transaction loss or payment processing gaps. |
| Shipping carrier & rate engine sync | BigCommerce's shipping setup (carriers, rate rules, dimensional weight) may not translate 1-to-1 to Shopify. Wrong rates or missing carriers frustrate customers and impact revenue. | RDA audits your shipping configuration, recreates all carrier integrations and rate rules in Shopify, and tests real-time rates. International shipping configured properly from day one. |
| Inventory across channels & marketplaces | If you sell on Amazon, eBay, or other channels, BigCommerce inventory sync breaks during migration. Overselling and customer cancellations follow without real-time sync. | RDA sets up inventory middleware to sync Shopify with all your marketplace channels in real-time. Single source of truth prevents overselling and keeps all channels aligned. |
| Email marketing & automation breakage | BigCommerce email lists and abandoned cart workflows may not transfer cleanly to Mailchimp, Klaviyo, or Klaviyo. Automation gaps mean lost recovery revenue. | RDA migrates all customer lists with purchase history intact, sets up Shopify webhooks for real-time list syncing, and rebuilds abandoned cart and post-purchase automation flows perfectly. |
| ERP, CRM & accounting software sync | If BigCommerce was connected to NetSuite, Salesforce, QuickBooks, or a custom ERP, that integration breaks during migration. Breaking data flow causes reconciliation and operational chaos. | RDA sets up Shopify APIs and integration middleware to maintain all downstream connections. Order, customer, and inventory data flows accurately from day one. |
| Analytics & conversion tracking loss | BigCommerce analytics and custom tracking (Google Analytics, heat maps, session recording) don't automatically transfer. Post-migration data is incomplete or breaks entirely. | RDA preserves historical analytics in a separate view, implements GA4 with enhanced ecommerce tracking, ensures UTM parameters flow correctly, and maintains full conversion visibility. |

Schedule Your Migration Strategy CallFrequently Asked Questions
How long will my BigCommerce store be offline?
Typically 2–4 hours during the final cutover window. We run a full dry-run in staging first to eliminate surprises. Most migrations happen during off-peak hours to minimize customer impact.
Can you preserve all my product images and assets?
Yes. RDA downloads all product images and assets from BigCommerce's CDN, uploads them to Shopify's CDN, and updates all image URLs in product descriptions. 100% of images verified before launch.
What happens to my SEO rankings during the migration?
With RDA's approach, your rankings are protected. We implement 301 redirects for every URL, set proper canonicals, submit updated XML sitemaps, and manage the migration crawl through Google Search Console. Most clients see minimal impact; many see improvements within 60 days.
How do you handle customer accounts and passwords?
BigCommerce and Shopify encrypt passwords differently, so passwords cannot be migrated for security reasons. RDA sends personalized password reset emails to all customers with clear instructions. Most customers reset within 24 hours. We monitor support channels closely during this period.
Can you migrate my BigCommerce apps and integrations?
BigCommerce apps don't directly port to Shopify, but RDA maps each one to a Shopify equivalent or custom solution. We test all features, ensure parity or identify better alternatives, and ensure everything works flawlessly on day one.
What is the typical cost of a BigCommerce to Shopify migration?
Cost depends on store complexity, catalog size, app/integration count, and custom functionality. Mid-market stores typically range $12k–$35k. Enterprise stores with complex customizations may be higher. RDA provides a fixed-price quote after the discovery audit.
How are customer orders and order history handled?
RDA migrates all orders with full audit trail, payment status, and customer notes. Abandoned carts are preserved as draft orders or imported into your email marketing platform. Complete order history remains searchable and accessible in Shopify.
Will my payment processors and shipping carriers still work?
Yes. RDA tests all payment methods and shipping integrations thoroughly in staging. We reconfigure them for Shopify, verify real-time carrier rates, and ensure everything works seamlessly on day one. Zero downtime for payment processing or shipping calculations.
