Building an Ecommerce Site in 2026: Shopify, WooCommerce or Custom

Decide the variables before the platform

Building an ecommerce website isn't one decision — it's six nested ones:

1. Which platform (Shopify, WooCommerce, Magento, custom)? 2. Which payment integrations (Stripe, Adyen, local PSPs)? 3. Which shipping integrations (DHL, UPS, regional carriers)? 4. ERP or accounting connection (NetSuite, SAP B1, Logo, Mikro)? 5. Multi-language / multi-country? 6. B2C or B2B (B2B brings tiered pricing, invoicing, credit limits)?

These six answers shape budget, timeline and team. This guide unpacks each.

1. Platform comparison (2026)

Shopify

• Largest ecosystem (10,000+ apps)
• $39-2,300/month (Plus included)
• Fast setup (2-6 weeks)
• Limited customization (Liquid + apps)
• Payments: Shopify Payments where available + Stripe/Adyen
• Best for: B2C, fast time to market, 100-50,000 SKUs

WooCommerce (WordPress)

• Fully customizable
• $50-500/month for hosting/licenses
• Setup 4-10 weeks
• Large plugin ecosystem
• High maintenance (WordPress + WooCommerce + plugins)
• Best for: mid-market B2C wanting flexibility

Magento (Adobe Commerce)

• Enterprise-grade
• $22,000+/year licensing (Cloud)
• 3-6 month setup
• B2B + B2C on the same platform
• High development cost
• Best for: 1,000+ SKUs, multi-country enterprise

Custom (Next.js + Medusa / Saleor / commerce.js)

• Full control
• 3-6 month setup ($15,000-75,000)
• Headless architecture
• Highest performance + SEO ceiling
• Best for: brand and performance as strategic investment, custom business rules

Practical rule: SMB starting fresh → Shopify; growing mid-market → WooCommerce; enterprise ecommerce → custom or Shopify Plus.

2. 2026 price ranges (Europe)

Numbers below assume professional team + custom design + core integrations:

Shopify (50-500 SKUs) — €7,000-18,000 setup, €60-700/month platform Shopify Plus (enterprise) — €25,000-65,000 setup, €1,200-3,500/month WooCommerce (50-500 SKUs) — €9,000-22,000 setup, €250-750/month maintenance Custom (Next.js + Medusa) — €25,000-75,000 setup, €600-2,500/month maintenance Magento Commerce — €50,000+ setup, €30,000+/year license

These are 2026 European market averages.

3. Payment integrations

Ecommerce platform decisions are 20% the payment side:

• Stripe — most international markets
• Adyen — enterprise multi-region
• Mollie — strong in EU
• PayPal — cross-border consumer
• Local PSPs — regional preference (iyzico, Klarna, Sofort)
• Apple Pay / Google Pay — mandatory for mobile checkout

Multi-PSP support is standard for mid-market. Single-PSP creates revenue risk during contract disputes.

---

4. Shipping integrations

Practical shipping integration list:

• DHL, UPS, FedEx — international
• DPD, GLS, Hermes — EU regional
• Royal Mail — UK
• Local carriers — country-specific
• Aggregators (ShipStation, Sendcloud) — multi-carrier from one API

API integration: label generation, tracking number, status webhooks, return labels. All major carriers offer these; mid-market stores typically run 2-3 carriers in parallel via an aggregator.

---

5. ERP and accounting integrations

Critical for businesses keeping stock and invoicing in a separate system:

• NetSuite, SAP B1 — enterprise
• Microsoft Dynamics 365 — mid-large enterprise
• Xero, QuickBooks — SMB-mid market
• Odoo — open-source ERP
• Local ERPs — country-specific (Logo, Mikro, Nebim)

Synchronized data:

• Product master + stock level (real-time or 5-min lag)
• Order → invoice automation
• Payment + collection
• Returns + return invoices

These integrations consume 20-30% of effort on enterprise ecommerce projects. Done right, they save 1-2 hours of ops time daily.

6. SEO: ecommerce-specific needs

Critical points for ecommerce SEO:

Product page

• Schema.org Product + Offer + AggregateRating
• Title format: "Product · Brand | Site"
• Description from features + category + benefits
• Image alt + WebP/AVIF
• Out-of-stock: not 404 — "back soon" + alternatives

Category page

• Filter URL canonical management (color=blue shouldn't index alone)
• Pagination + rel="next/prev"
• Category description (200-400 words)

On-site search

• "Product not found" page is not a 404
• Search URLs blocked in robots.txt

Performance

• Mobile LCP < 2.5s — directly tied to conversion
• INP < 200ms — critical for cart/checkout interactions
• Static generation (ISR) for category + product pages on edge cache

Ecommerce SEO in 2026 barely works without Lighthouse 90+.

7. Mobile experience and checkout

75%+ of ecommerce traffic is mobile in 2026. Mobile checkout rules:

• Guest checkout mandatory (forced signup = ~30% dropoff)
• Address autocomplete (Google Places or local)
• PCI-compliant card storage (tokenized)
• Frictionless 3D Secure
• Apple Pay / Google Pay support
• One-click reorder
• Cart abandonment email at 1h + 24h + 3d

Checkout shouldn't exceed 3 steps. Each extra step costs 7-10% of conversion.

---

8. B2B ecommerce specifics

B2B ecommerce differs from B2C in 5 places:

1. Tiered pricing — different prices per customer group 2. Credit limit + net-terms billing — order approval flow 3. VAT inclusive/exclusive display — buyer preference 4. Multiple billing/shipping addresses 5. Bulk order upload — Excel/CSV

Shopify Plus B2B, Magento or custom platforms handle these. Standard Shopify and WooCommerce are limited.

9. Marketplaces vs. your own store

With Amazon, eBay and large regional marketplaces around, does an own ecommerce store still make sense?

Marketplace pros:

• Built-in traffic
• Fast start
• Simple ops

Marketplace cons:

• 15-30% commission
• Weak brand building
• Customer data not yours
• Price pressure
• Marketplace sets the rules

Healthy strategy: start on marketplace, build own store within 12 months, target 40-60% of total sales from own store within 24 months. This balances cash flow with brand value.

---

10. Team + maintenance

Ecommerce is a live system, not "set and forget":

• Store manager (content + category + product) — full-time at mid-scale
• Marketing (ads + email + SEO) — full-time or agency
• Technical maintenance — 30-80 hours/month
• Customer service — scales with order volume

Without a maintenance contract, sites slow down 30-40% within 6 months (plugin + content drift).

11. Decision checklist

8 questions for the platform decision:

1. 1,000+ orders per month expected? 2. 5,000+ SKUs? 3. B2B + B2C on the same platform? 4. ERP integration mandatory? 5. Multi-language / multi-country? 6. Brand control and performance critical? 7. Development budget €25K+? 8. 5-year platform investment planned?

3+ "yes" → custom or Shopify Plus 1-2 "yes" → Shopify or WooCommerce 0 "yes" → Shopify Basic

---

12. Closing

In 2026, building an ecommerce site is a business-model decision before a platform one: B2C, B2B or hybrid; marketplaces only or own store; ERP-integrated or not. Once those are locked, the platform falls out in an hour-long analysis.

Wrong platform is expensive in ecommerce: migrations come due in 18-24 months and cost ~1.5× a fresh build.
