Launching an e-commerce site in 2026 comes down to two main paths: ship fast on a hosted platform like Shopify, or build your own store from scratch with Next.js + a custom backend. Which is right for you? The answer comes from numbers as much as from brand identity. Below we compare total cost of ownership, performance, SEO, flexibility and long-term viability.
Two main paths
Hosted platform (Shopify, WooCommerce, Magento, Wix Commerce)
Monthly subscription for everything: storefront, cart, payment, inventory, admin. Pick a theme, upload products, sell. Shopify is the leader; WooCommerce (WordPress plugin) remains common.
Custom-coded (Next.js + headless commerce or full custom)
Built from scratch. Headless: frontend in Next.js, backend from Shopify Plus / Medusa / Saleor / your own. Full custom: both frontend and backend yours. Higher upfront cost, far higher flexibility.
Total cost comparison (3 years)
For a store doing 10,000 orders/year at an average $25 basket ($250k/year revenue), 3-year totals:
| Item | Shopify | Custom |
|---|---|---|
| Initial build | $400-$1.5k (theme + setup) | $3k-$8k |
| Monthly subscription | $200-$600/month | $0 (your hosting) |
| Transaction fee (per sale) | 0.5-2% (outside Shopify Payments) | Only payment provider (Stripe ~2.9% + $0.30) |
| Hosting | Included | $20-$120/month (VPS) |
| App/plugin cost | $25-$120/month (10-30 apps) | $0 — built in |
| Developer maintenance (yearly) | $200-$800 | $800-$2.4k |
| 3-year total (rough) | ~$14k-$24k | ~$11k-$20k |
Result: over 3 years, custom is usually cheaper. Shopify looks attractive at start, but subscriptions + apps stack up. At low volume Shopify wins; at high volume custom always wins.
SEO and performance
Custom has a dominant edge here:
Shopify
- Theme structures are average for SEO. URL structure breaks on theme change.
- Core Web Vitals: LCP usually 3-5s. Theme bloat is the issue.
- Structured data (JSON-LD): comes from theme, scope limited.
- URL structure: fixed (e.g.
/products/abc); hard to override.
Custom (Next.js)
- Full SSG / ISR pushes page speed to 1-2s.
- Lighthouse 95+ routinely.
- JSON-LD: Product, BreadcrumbList, Review, AggregateRating, FAQPage — as much as you want.
- URL structure fully in your hands.
- Cloudflare/Vercel edge for global caching.
SEO is the most important traffic channel for an e-commerce store. The compounding savings on ad spend make this gap meaningful over years.
Flexibility
Easy on Shopify:
- Standard storefront, cart, checkout flow.
- Inventory and order management.
- Quick feature add via app marketplace.
Hard (or impossible) on Shopify:
- Multi-store / B2B portal / reseller flow.
- Complex product configurator (custom machines/parts/accessories).
- Custom checkout (closed outside Shopify Plus).
- Country-specific compliance (Turkish KDV, e-invoice; iyzico isn't deeply integrated).
- Make the homepage exactly what you want (theme limits).
Custom has no such limits — but every feature is dev time. The trade is speed vs flexibility.
Payments: a critical topic for Türkiye
For e-commerce in Türkiye, payment provider choice matters:
- iyzico, PayTR, Param: local; supports KDV, installments, BKM. On Shopify they integrate side-channel; sometimes a theme tweak is needed. Custom uses native libraries directly.
- Stripe: best for international sales. Native on Shopify. TRY-USD conversion can sting Turkish buyers.
- Crypto (USDT, TRC20): bonus for international buyers. Easy to integrate in custom.
When Shopify, when custom?
Pick Shopify if:
- Making your first sales; still testing the market.
- Monthly revenue under $50k, simple storefront suffices.
- No technical team and no plan to hire devs.
- Fast launch is critical for test/MVP.
Pick custom if:
- Brand differentiation in look/feel matters.
- Monthly revenue $250k+; subscriptions + apps are eating margin.
- You need B2B, multi-store, custom configurator.
- You want aggressive SEO growth — performance + flexibility critical.
- You have a 3+ year plan — ready for long-term investment.
Hybrid: headless commerce
Third path: headless commerce. Backend Shopify Plus, Medusa or Saleor; frontend Next.js. You use Shopify's payment, inventory and order engine but fully control the frontend. SEO and performance at custom level, backend management easier.
We use this approach often in our e-commerce service — especially for the $150k-$1M annual revenue band.
Wrap-up
The right answer isn't "Shopify" or "custom" — it's "where am I now". Start year one on Shopify, grow revenue, then move to custom — a healthy path we see often. Or start custom and outrun your competitors on performance + SEO for 3 years.
