BigCommerce to Shopify Plus migration
We migrate BigCommerce stores to Shopify Plus from Melbourne, LA, and London. BigCommerce is a capable platform - the brands leaving aren't running from it. They're running toward more integrations, a more customisable checkout, and a deeper developer ecosystem.
We handle the full move: products with complex variants, customers with B2B configurations, order history, content, integrations, and SEO. You keep selling while we rebuild.

Every Stencil theme customisation, every third-party app, every custom field and option set. We document what each one does, what breaks if it stops, and what replaces it in Shopify Plus. BigCommerce's tiered plan structure often forces upgrades at revenue thresholds - we document what's costing you now and what Shopify covers natively.
BigCommerce Stencil themes don't transfer to Shopify Liquid. We redesign or port the existing brand into a Shopify theme or Hydrogen frontend, depending on your roadmap. Mobile-first by default.
BigCommerce product option sets map to Shopify variants, with careful handling of Shopify's 100-variant-per-product ceiling. Customer groups map to Shopify customer tags or Shopify B2B company profiles depending on complexity. Full order history preserved with reconciled counts.
BigCommerce's /categories/ URL structure maps to Shopify's /collections/. We build the full 301 redirect map, test it through a crawler pre-launch, migrate metadata and structured data, and monitor Search Console through the first four weeks post-launch. Rankings typically stabilise by week four.
ERPs, 3PLs, loyalty, email, subscriptions, reviews. Shopify APIs first. Middleware only where they don't reach. Parallel environments, stakeholder UAT, DNS switch in a low-traffic window, on-call through the first 48 hours.
- Ship before product and customer data reconciles 1:1. If it doesn't match, we don't launch.
- Sign off on a redirect map we haven't tested. Every redirect runs through a crawler pre-launch.
- Push headless when your roadmap doesn't need it. We've shipped plenty of classic Plus builds for brands that didn't need more.
- Run your migration as a side-project. Lead engineer, PM, and QA owner named and allocated on every migration.
Classic Shopify Plus is usually the right call at migration. Theme-based builds launch faster and cover the B2B, Markets, and Checkout Extensibility features most brands came for.
Hydrogen is the longer-term bet. You get design control and performance the theme layer can't match. We build on Remix with Sanity for content, Algolia or Tagalys for search depending on the catalogue.
Phased path is often the answer: classic now, Hydrogen when the roadmap actually needs it. Migration is the wrong moment to over-scope.
Frequently Asked Questions about
BigCommerce to Shopify Plus Migration
If you have more questions, we're happy to answer them - just reach out.
How long does a BigCommerce to Shopify Plus migration take?
8 to 12 weeks for most mid-market BigCommerce stores. Larger enterprise BigCommerce installs with complex B2B setups or multi-storefront configurations sit at the longer end. Simpler stores without heavy Stencil customisation skew shorter.
Will I lose my Google rankings moving off BigCommerce?
Not if redirects are done properly. BigCommerce uses /categories/ while Shopify uses /collections/, so URL mapping and 301 redirect logic is essential. We build the full redirect map, test through a crawler pre-launch, migrate metadata and structured data, and monitor Search Console through the first four weeks post-launch.
What happens to our BigCommerce product option sets?
BigCommerce product option sets map to Shopify variants, watching Shopify's 100-variant-per-product ceiling. For products exceeding that, we split into variant groups or use a metafield-driven configurator. Bundles and custom options rebuild as Shopify apps or Hydrogen components depending on architecture.
Can we migrate B2B customer groups and tiered pricing?
Yes. BigCommerce customer groups map to Shopify customer tags for simple cases, or Shopify B2B company profiles for brands with wholesale pricing, payment terms, or purchase orders. Tiered pricing and catalogue rules rebuild using Shopify B2B price lists or Shopify Functions.
Do we stay on BigCommerce during the build?
Yes. Your BigCommerce store keeps running until DNS cutover. We build in parallel environments, migrate data in stages, and run a final data sync the night before launch. No sales pause, no downtime during the transition.
