The Cost of Staying
Two realities. One platform decision.
Your platform charges more as you grow
BigCommerce’s revenue-based pricing model turns your own success against you. At $500K gross merchandise value you pay more per month than competitors generating the same revenue on Shopify.
Gross merchandise value-tiered pricing penalises revenue growth
Cross $400K and your plan cost jumps automatically, not optional.
A smaller app ecosystem
Shopify’s app store is 4x larger. Most tools you want are Shopify-first.
Checkout customisation is locked
Shopify Plus’s Checkout Extensibility gives you full control. BigCommerce doesn’t.
Fewer developers know BigCommerce
Liquid skill sets are 10x more available. Hiring or extending your stack is faster on Shopify.
A platform that gets cheaper to operate as you scale
Shopify’s flat pricing model means you keep the revenue you earn. Your platform cost stays predictable while your store grows.
Flat monthly pricing regardless of revenue
Scale from $100K to $10M without your platform bill following you.
8,000+ apps natively integrated
Klaviyo, Recharge, Attentive, Gorgias, all built first for Shopify.
Full checkout extensibility on Plus
Custom upsells, loyalty redemption, and branded flows, all at checkout.
The world’s largest developer community
Any feature you need has already been built or can be built by someone nearby.

What’s Included
Everything your migration includes
A complete migration isn’t just moving data. It’s rebuilding your store so it converts better on day one.
Full data migration
Every product, variant, SKU, image, order history, customer account, and metafield moves intact. You never re-enter a single record manually.
Products and variants
Customer accounts
Order history
Custom metafields
Search engine optimization preservation
Complete 301 redirect mapping, meta title and description transfer, canonical setup, and Google Search Console sitemap submission before cutover.
Theme development
A custom Shopify theme built to convert, not just a clone of your BigCommerce layout. Mobile-first, fast, and built on Liquid best practices.
App and integration rebuild
Every tool you use, email, loyalty, reviews, analytics, reconfigured and tested in Shopify before launch. No gaps on go-live day.
Zero-downtime cutover
Your BigCommerce store stays live and taking orders right up until the moment your Shopify store is ready. DNS cutover takes minutes, not days.
BigCommerce live until DNS switch
Client Result
A migration that paid for itself
Client
Dr. Dee Blanco
Holistic Veterinary and WellnessA wellness brand that was locked into WordPress and needed a scalable, high-performing ecommerce platform to grow their product catalogue.
The problem
The existing WordPress site required days of developer time for any product update. Performance was poor, checkout abandoned at a high rate, and search engine optimization rankings were hard to maintain during the platform move. Every change slowed the team down.
The result
0%
downtime during cutover
Custom Shopify theme, complete data migration with zero loss, search engine optimization preserved and improved, conversion rate increased on day one. The store relaunched faster than planned and the brand’s organic traffic grew within 30 days.
How the Migration Works Technically
Zero data loss. No manual re-entry.
Select any node to see how each part of your BigCommerce stack maps to Shopify.

Product catalogue migration
We use the BigCommerce Catalog API to export every product with its title, description, images, variants, pricing, inventory, and custom fields. A normalisation layer maps BigCommerce data structures to Shopify’s product schema.
Variants, options, and inventory levels
Product images (original resolution)
Custom fields mapped to Shopify metafields
Collection and category structure rebuilt
Search engine optimization preservation architecture
We crawl your entire BigCommerce URL structure using Screaming Frog, export every indexable URL, and build a 301 redirect map before a single DNS record changes. Nothing goes live until every redirect is tested.
Full 301 redirect map verified pre-launch
Meta titles and descriptions transferred
Canonical tags configured on Shopify
Search Console sitemap submitted at launch
Customer account migration
Customer records, addresses, and order history all migrate fully. Passwords cannot be transferred due to hashing, customers receive a branded invitation email to set a new Shopify password. Open rate on these emails is above 45%.
Customer name, email, and address data
Lifetime order history linked to account
Branded password-reset email at launch
Passwords (cannot be migrated, by design)
Order history migration
Historical orders are imported via Shopify’s Order API with all line items, totals, discounts, fulfilment status, and shipping details intact. Your team’s reporting, lifetime value data, and loyalty calculations all work from day one.
Line items, discounts, and totals
Fulfilment and shipping status
Customer-linked order history
Lifetime value and repeat purchase data intact
Why Choose Redefine
Why teams choose Redefine over other migration partners
Most migration agencies re-import your data and call it done. We rebuild your store to convert better on Shopify than it did on BigCommerce.
| Capability | Typical migration partner | Redefine |

| Custom theme development (not a BigCommerce clone) | ||
| 301 redirect mapping and search engine optimization verification before launch | ||

| Fixed-price scoped proposal before any commitment | ||
| Zero-downtime DNS cutover process |
Common Questions
Questions before committing
Not if the migration is done correctly. Every URL on your current store gets a verified 301 redirect to its Shopify equivalent before the DNS switches. We test the entire redirect map, transfer your meta titles and descriptions, submit the new sitemap to Search Console at go-live, and monitor your rankings for 30 days after launch. Clients who migrate with us maintain or improve their organic rankings.
Customer names, emails, addresses, and complete order history all migrate without loss. Passwords cannot transfer between platforms. BigCommerce hashes them in a way Shopify cannot read, and this is true for every migration between any two platforms. Customers receive a branded invitation email to set a new Shopify password. Open rates on these emails are above 45%, and the experience feels like an upgrade rather than a disruption when the email is written well (we write it for you).
No. Your BigCommerce store remains fully live and accepting orders right up until the moment your Shopify store is ready to go. The DNS cutover itself takes minutes. We schedule it during your lowest traffic window, monitor both stores in parallel during propagation, and stay on standby for 24 hours after cutover.
Migration pricing depends on the size of your catalogue, the complexity of your custom theme requirements, and the number of third-party integrations that need to be rebuilt on Shopify. We scope line-by-line before any work starts, no surprises. Submit your brief and we’ll send a detailed proposal within three business days. You can also see a pricing overview on our migration cost page.
If your store generates more than $1M gross merchandise value annually, Plus gives you checkout extensibility, Scripts, B2B native features, multi-store management, and dedicated account support. Below that threshold, standard Shopify covers most needs. We’ll recommend the right plan in your migration assessment, and if you’re on BigCommerce’s higher gross merchandise value tiers, Plus often costs less per month than what you’re paying now. See our Shopify Plus migration page for enterprise-specific detail.
