BigCommerce Migration to Open-Source Commerce
Move off BigCommerce. Land on Medusa.js + Next.js + Square. No platform fees, no feature gates, no permission to innovate.
Three Ways BigCommerce Limits Your Growth
BigCommerce Plus to Enterprise jumps from ~$105/month to $400+/month with revenue thresholds that force upgrades. The platform gets more expensive exactly when your margins are tightest.
Stencil templates and the API surface cover 80% of use cases cleanly. The remaining 20% — custom checkout logic, B2B pricing, multi-vendor — requires workarounds that accrue technical debt.
BigCommerce's Square connector handles basic catalog and payments. It does not support Square gift cards, loyalty, multi-location inventory governance, or real-time POS sync at the data model level.
The Migration Process
1. Discovery (1–2 weeks)
We audit your BigCommerce store: theme customizations, third-party apps, API integrations, SEO footprint, and data volume. We produce a migration scope with risk items flagged before a line of code is written.
2. Data Migration (2–3 weeks)
Products, variants, customers, orders, and reviews are migrated to Medusa. Every SKU, every order history record, every customer account — with data validation before cutover.
3. Build (8–12 weeks)
Next.js storefront built to your design system. Medusa backend configured with your business logic. Square payments, gift cards, and catalog sync wired natively.
4. SEO Preservation (cutover week)
Every BigCommerce URL gets a 301 redirect mapped before launch. We monitor Search Console for crawl errors and fix them within 48 hours of cutover.
5. Post-Launch Stabilization (30 days)
Performance monitoring, edge case fixes, SEO tracking, and on-call support for 30 days after go-live. No abandonment at the finish line.
Own Your Commerce Stack Permanently
Medusa.js is MIT-licensed open-source. Next.js is open-source. You pay for hosting (GCP Cloud Run runs under $200/month for most stores), not for the software.
Our medusa-square-plugin is the only published bidirectional Square integration for Medusa v2. Catalog sync, payments, gift cards, OAuth — all production-ready.
You get the repository. Your team can read, modify, and extend every line. No black-box platform behavior, no vendor negotiation to change checkout flow.
