How much does e-commerce development cost?

Custom e-commerce development starts from $8,000 for Shopify stores and goes up to $80,000+ for fully bespoke platforms. Pricing depends on product catalog size, payment integrations, and custom features.

Shopify vs custom e-commerce - which should I choose?

Shopify is ideal for businesses starting out or with standard needs (under $5M revenue). Custom-built platforms suit businesses needing unique checkout flows, complex product configurations, or multi-vendor marketplaces.

How long does it take to build an online store?

Shopify stores take 2-4 weeks. Custom e-commerce platforms take 8-16 weeks depending on catalog complexity, payment integrations, and custom features like subscriptions or marketplaces.

Can you optimize my store's conversion rate?

Yes, WH Studio implements conversion optimization best practices including fast page loads, streamlined checkout, trust signals, A/B testing, and analytics tracking. Average conversion improvements of 30-60%.

Do you integrate payment gateways?

We integrate all major payment providers including Stripe, PayPal, Square, and Apple/Google Pay. We also implement buy-now-pay-later options like Klarna and Affirm.

Deep dive

What modern e-commerce engineering actually demands.

E-commerce has stopped being a Shopify theme decision and become a platform engineering one. Headless commerce, edge personalisation, and composable checkout are the floor in 2026 — not the ceiling.

Headless or hybrid — chosen on purpose

Next.js + Shopify Hydrogen or Medusa.js for greenfield. BigCommerce or Shopify Plus + custom storefront for migrations. Each choice has a clear ROI threshold tied to SKU count, traffic, and personalisation needs — we won't recommend headless to a store that doesn't need it.

Conversion-rate engineering

Speed is the highest-leverage conversion lever. Every 100ms of LCP improvement is worth 1–2% conversion at scale. Our default builds hit sub-1.5s LCP on 75th-percentile mobile traffic, with edge caching, image pipeline tuning, and aggressive code splitting baked in.

Checkout that doesn't lose 30% of carts

Express checkout (Apple Pay, Shop Pay, Google Pay) on the product page, not just the cart. Address autocomplete via Google Places. Tax and shipping calculated synchronously, not on submit. Together these typically lift checkout completion 8–15%.
