SaaS Platforms: Shopify, BigCommerce, and WooCommerce
Shopify dominates the SaaS e-commerce space for good reason: it handles hosting, security, payment processing, and updates out of the box. For businesses doing under $1M in annual revenue, it's almost always the right choice. You're selling products, not building technology. Shopify Plus extends this to enterprise needs with checkout customization, multi-store management, and B2B features. However, SaaS platforms charge transaction fees, limit customization depth, and can create vendor lock-in.
WooCommerce offers more flexibility as an open-source WordPress plugin, but requires managing hosting, security, and plugin compatibility yourself. BigCommerce sits between Shopify and custom, offering strong built-in features with more API flexibility. Our e-commerce developers have built stores on all major platforms and can guide you to the right fit based on your specific product catalog, market, and growth targets.
Custom-Built and Headless Commerce
Custom e-commerce makes sense when your business model doesn't fit a template: complex pricing rules, unique checkout flows, deep ERP integration, multi-currency B2B operations, or marketplace features. A headless approach—using Shopify, Medusa, or Saleor as the commerce engine with a custom Next.js or Nuxt frontend—gives you the best of both worlds: robust commerce infrastructure with unlimited frontend flexibility. Our SaaS development team specializes in headless commerce architectures that deliver blazing-fast storefronts with sub-second page loads.
The Total Cost of Ownership (TCO) Comparison
Shopify Basic starts at $39/month but real costs include themes ($250-$350), apps ($200-$500/month for a typical stack), and transaction fees (0.5-2%). A realistic Shopify TCO for a growing store is $800-$2,000/month. A custom build costs $30,000-$150,000 upfront with $1,000-$3,000/month in hosting and maintenance. The break-even point typically comes at $2-5M in annual revenue, where transaction fee savings offset development costs. Smart SEO and performance optimization is critical regardless of platform choice—fast, well-structured stores rank higher and convert better.
"The best e-commerce platform is the one that matches your growth trajectory."
— Tobias Lütke, Shopify CEO
Conclusion
There's no universal answer. Start with Shopify if speed to market matters most. Go custom when your business model demands it. And consider headless commerce as the bridge between the two. Let our e-commerce team architect the platform strategy that matches your ambition.
