Definition

What is Open SaaS?

Open SaaS combines the best of both worlds: open-source flexibility (full API access, webhooks, high extensibility) with SaaS operational security (managed hosting, automatic updates, 99.99% SLA). BigCommerce invented the term.

In practice: your frontend is 100% yours (Next.js, React, any framework). The backend (catalog, checkout, orders, inventory) is BigCommerce. GraphQL and REST APIs expose everything. You integrate with ERP via real-time webhooks. Scale to Black Friday without provisioning servers. Data hosted on European servers for GDPR compliance.

Why

Headless, B2B, Multi-Storefront

BigCommerce for enterprise architectures

BigCommerce is not "Shopify with a different name". It is Open SaaS: API-oriented (450 calls/s vs 40 from Shopify), native B2B Edition with Net Terms and Price Lists, multi-storefront from one backend. No Magento maintenance, with the flexibility that Shopify does not offer.

Summary

For the CEO

The business value of BigCommerce B2B.

Magento consumes 40% of your IT team's time on patches, updates and maintenance. That hidden cost translates to lost opportunities and operational slowness.

BigCommerce B2B Edition offers native functionalities that Magento only offers through third-party modules: Net Terms, Price Lists, approval workflows. All maintained by BigCommerce, not your team.

Typical migration ROI is 8-12 months: IT savings + conversion improvement + reduced operational friction. Companies with €5M-€50M turnover see the fastest return.

  • -65% IT Cost
  • 8-12 Months ROI
  • GDPR Compliant

For the CTO

For the CTO

BigCommerce technical architecture.

BigCommerce is API-first: GraphQL for storefront, REST for management. Rate limits of 450 calls/second (vs 40 for Shopify). Webhooks for real-time synchronization with ERPs.

Headless with Next.js: frontend on Vercel/AWS CloudFront, BigCommerce backend. Catalogs of 200K+ SKUs without degradation. Algolia for search if catalog requires it. For a full MACH architecture, see our composable commerce service.

ERP integrations: native connections with SAP, Dynamics, Navision. For legacy ERPs (AS/400, JD Edwards), Node.js/Python middleware on AWS Lambda. No manual CSVs.

FAQ

Frequently Asked Questions

What decision-makers ask.

Why BigCommerce and not Shopify Plus for B2B?

Shopify Plus has API limits (40 calls/second vs 450 for BigCommerce) that break ERP integrations at scale. Shopify's B2B is a recent and limited add-on: no native Net Terms, no purchase order workflows, no multi-level approval. BigCommerce B2B Edition has 5+ years in production.

Can you migrate from Magento without losing data?

Yes. We migrate products with complex variants, categories, customers with price lists, historical orders, and configure 301 redirects to preserve SEO. 80% automated process. We've migrated catalogs of +100K SKUs.

What about my legacy ERP (AS/400, JD Edwards)?

We connect with any ERP that has an API or can export files. For legacy systems we deploy Node.js/Python middleware (AWS Lambda) that acts as translator. Experience with AS/400, JD Edwards, Sage.

Does BigCommerce support +50K SKU catalogs?

No problem. For large catalogs we recommend headless with Algolia for faceted search. We've implemented catalogs of 200K+ SKUs with response times <500ms.

Is it GDPR compliant?

Yes. BigCommerce offers hosting on European servers. We configure CMP and GDPR-compliant retention policies. Compliance audit included.

What is the BigCommerce license cost?

BigCommerce B2B Edition: approximately €1,000-€3,000/month depending on GMV. No transaction fees. Includes hosting, security and automatic updates.

How long does migration take?

Typical B2B migrations: 10-14 weeks. Depends on catalog complexity, number of ERP integrations, and custom frontend requirements.

What if BigCommerce doesn't work for us?

All data is exportable. No vendor lock-in. The headless frontend is your code. You can migrate to another platform keeping the frontend.
