The short answer

BigCommerce-to-WooCommerce migration takes 25-35 days and costs $10K-$30K. The data export is cleaner than Shopify (BigCommerce’s API is more comprehensive), but B2B features (price lists, customer groups) require careful re-implementation in WooCommerce.

№ 01The longer answer

BigCommerce’s API is more comprehensive than Shopify’s, so data export is generally cleaner. We pull products, variants, customer groups, price lists, customers, orders, and reviews via the BigCommerce v3 API. Reconciliation in WooCommerce takes 2-4 days depending on B2B complexity.

The translation that needs the most care is BigCommerce’s native B2B features. Customer groups become WooCommerce user roles (typically via B2BKing or WooCommerce B2B). Price lists become role-based pricing rules. Quote workflows become YITH Request a Quote or custom workflow. Each translates with care; the work is in scenario testing across 10-20 customer types.

Migration cost factors: product count, customer-group count (more groups = more pricing rules), order history (5+ years adds time), and whether you’re moving the storefront design forward at the same time. Most clients migrating off BigCommerce do so because they’ve hit a customization ceiling — so a redesign typically goes with the migration.

SEO preservation works the same as Shopify: full 301 redirect map, rankings dip briefly, recover and often improve. BigCommerce-to-WooCommerce migrations we’ve done show 12-25% post-migration conversion lift, primarily from frontend performance improvements (Kinsta-hosted WooCommerce typically beats BigCommerce Pro on LCP by 0.4-0.8s).

№ 02Can I migrate B2B price lists cleanly?

Yes, via B2BKing or WooCommerce B2B + Dynamic Pricing. Up to ~6 customer groups translates cleanly; beyond that, per-customer pricing logic gets complex and requires custom code.

№ 03What about Stencil theme code?

Stencil is BigCommerce-proprietary and doesn’t translate. The frontend is rebuilt from scratch in WordPress block themes. We use the migration as a redesign opportunity.

№ 04How long does the data import take?

Bulk import: 4-8 hours for a 5,000-product catalog with customer history. Reconciliation and edge-case fixes: 2-4 days. Full data layer ready for staging QA by Day 7-10.
