You've decided to sell online. But the first real decision isn't about features or design—it's about the platform. Shopify, WooCommerce, Magento, or a custom build? Each choice affects your costs, scalability, hiring, and ultimately, your profitability.

I've built 45+ ecommerce systems for clients ranging from solo drop-shippers to multi-million dollar retailers. I've watched business owners waste $80K on Shopify because they chose wrong for their volume. I've seen custom builds that paid for themselves in 6 months. And I've seen WooCommerce stores that scaled effortlessly because they chose well.

In this guide, I'll break down every ecommerce platform option: what it costs upfront and at scale, who it's built for, and how to choose the right one for YOUR business model and budget.

TL;DR

Shopify if you want simplicity and don't mind paying 2.9% + $0.30 per transaction. WooCommerce if you own your hosting and want flexibility. Magento if you have 10K+ daily orders and need enterprise features. Custom build if you have >$200K budget and need specific logic no platform provides. For 95% of businesses starting in 2026: Shopify (simplicity) or WooCommerce (control). Platform choice is less important than execution—pick one and get it live.

The Four Ecommerce Paths

Every ecommerce business chooses one of four paths. Each has a cost, time-to-launch, and scaling ceiling.

Path 1: Hosted Platform (Shopify)

You pay a monthly fee. The platform handles hosting, updates, security, PCI compliance.

Best for: Startups, product-based businesses, anyone who values simplicity over control.

Path 2: Self-Hosted Software (WooCommerce, Magento)

You own the software; you're responsible for hosting, updates, and security.

Best for: Businesses that want flexibility, developers who want control, teams that can manage infrastructure.

Path 3: Marketplace (Amazon, eBay, Etsy)

You list products; the platform handles everything. You pay commission.

Best for: Businesses with existing products looking for quick distribution, sellers who don't want to manage their own brand.

Path 4: Custom Build

You build from scratch using your own codebase.

Best for: High-volume businesses with unique requirements, companies that can justify $150K–$500K investment.

This guide focuses on Paths 1-4. We'll ignore marketplaces because if you're reading this, you likely want to own your customer relationship.

Platform Comparison: Costs, Pros, Cons

Shopify

What it is: Hosted, fully managed ecommerce platform. No setup, no server management.

Pricing:

  • Basic: $39/month (unlimited products, 2 staff accounts)
  • Standard: $105/month (professional reporting, gift cards)
  • Premium: $399/month (advanced reports, 15 staff accounts)
  • Plus: $2,300+/month (custom solutions, 125+ staff accounts)
  • Transaction fees: 2.9% + 30¢ per order (no fees on Shopify Payments)

Timeline to launch: 3–6 weeks (you handle content/products; Shopify handles everything else).

Setup cost: $5K–$15K (design, product loading, integrations). Some businesses launch for free with built-in themes.

Pros:

  • Instant launch. No coding needed; anyone can build a store.
  • Low risk. Month-to-month billing; exit anytime.
  • Security included. PCI DSS Level 1 compliance; Shopify handles payment processing.
  • Massive app ecosystem. 10K+ apps (email, inventory, accounting, shipping).
  • Huge hiring pool. If you need to hire, Shopify experts are abundant.
  • Automatic updates. You never manage servers or security patches.
  • Global scaling. Shopify's infrastructure handles traffic spikes.

Cons:

  • Locked-in. You can't modify core platform functionality.
  • Expensive at scale. 2.9% per transaction adds up. At $100K/month revenue (4% conversion), you pay $2,900/month in transaction fees PLUS $2,300/month plan = $5,200/month ($62K/year).
  • Limited customization. Can't build features outside Shopify's app ecosystem.
  • Theme limitations. Design options are bounded by available themes.
  • Long-term control. Your entire business runs on Shopify's infrastructure and terms.

Best for: Dropshippers, small businesses, first-time sellers, anyone launching in <6 weeks.

Real example: A founder launched a sustainable home goods store on Shopify. 8 weeks from idea to $50K revenue. Paid $39/month + $1,450 transaction fees that month. After 2 years and $1.2M annual revenue, he stayed on Shopify. Transaction fees: $35K/year. Not optimal, but simplicity was worth it. He didn't want to hire a CTO.

WooCommerce

What it is: Open-source WordPress ecommerce plugin. You host it yourself.

Pricing:

  • Software: Free
  • Hosting: $10–$100+/month (depends on traffic and hosting provider)
  • Extensions: $50–$500/month (payment processing, shipping, accounting integrations)
  • Payment processing: 2.9% + 30¢ per transaction (varies by provider)

Timeline to launch: 4–8 weeks (similar to Shopify, but you manage hosting).

Setup cost: $3K–$12K (design, theme customization, plugin setup, hosting configuration).

Pros:

  • Open source. Full control over code; can customize anything.
  • Flexible hosting. Choose any hosting provider (cheaper or better than Shopify).
  • No licensing fees. Software is free.
  • Mature ecosystem. 1,000+ plugins; everything is cheaper than Shopify apps.
  • Own your data. Complete control over customer data and backups.
  • Better at scale. Hosting costs scale with usage; no per-transaction fees like Shopify.
  • Better for SEO. WordPress is SEO-native; Shopify is getting better but still behind.

Cons:

  • You're responsible for hosting. Server crashes = you fix it.
  • Security is on you. Install updates, manage SSL certificates, prevent hacks.
  • Scaling requires technical knowledge. As traffic grows, you need infrastructure management.
  • Smaller hiring pool. WooCommerce developers exist but are less abundant than Shopify experts.
  • Steeper learning curve. Not for non-technical founders.
  • Can be slow. Poorly configured WooCommerce is slow; Shopify is always fast.

Best for: Developers, technical founders, businesses that want control, medium-sized shops ($50K–$1M annually).

Real example: A fashion brand started on WooCommerce. Hosting: $30/month. Plugins: $150/month. Transaction fees: $1,200/month (at $40K revenue). Total: $1,380/month. On Shopify, they'd pay $5,200/month at the same revenue level. Difference: $45.6K/year. They hired a developer ($60K/year) to manage the store. Still ahead. Scaling was easy; WooCommerce handled 10x growth without issue.

Magento

What it is: Enterprise-grade, open-source ecommerce platform. For high-volume, complex shops.

Pricing:

  • Magento Open Source: Free
  • Adobe Commerce (formerly Magento Commerce Cloud): $40K–$150K+/year
  • Hosting (self-hosted): $100–$1K+/month
  • Integrations & extensions: $500–$5K/month
  • Developer team: $150K–$500K/year (you need specialists)

Timeline to launch: 12–24 weeks (complex; requires development team).

Setup cost: $50K–$200K (comprehensive development, customization, testing).

Pros:

  • Enterprise-grade. Handles massive scale (1M+ daily orders).
  • Flexible. Can build any feature you want.
  • Multi-store support. Manage multiple storefronts from one platform.
  • Advanced features. B2B, wholesale, complex inventory management.
  • Performance at scale. Optimized for high traffic and large catalogs (100K+ SKUs).
  • Complete control. Own everything; no vendor lock-in.

Cons:

  • Expensive. You're paying for enterprise-grade software and expertise.
  • Complex. Steep learning curve; requires skilled developers.
  • Slow to launch. 3–6 months minimum to go live.
  • Heavy. Can be overkill if you don't need enterprise features.
  • Hiring is expensive. Magento developers command premium salaries ($150K+).
  • Maintenance burden. You're responsible for updates, security, performance.

Best for: High-volume retailers, multi-brand companies, B2B ecommerce, international sellers with complex requirements.

Real example: A furniture retailer with 8K SKUs, 500K monthly visitors, and $5M annual revenue needed Magento. Shopify couldn't handle inventory complexity. WooCommerce was too slow. Magento cost: $100K setup + $60K/year hosting + $200K/year development team. But they handle 50K orders/week without scaling issues. For their scale, Magento justified itself in year 1.

Custom Build

What it is: You code your entire ecommerce platform from scratch.

Pricing:

  • Development: $150K–$500K+ (depends on complexity and timeline)
  • Hosting: $50–$500+/month
  • Team (ongoing): $200K–$600K/year (you need engineers)
  • Payment processing: 2.9% + 30¢ per transaction

Timeline to launch: 16–32 weeks (custom development is slow).

Setup cost: $150K–$500K.

Pros:

  • Total control. Build exactly what you need, nothing more.
  • Unique features. Competitive advantages you can build, but competitors can't copy easily.
  • Optimized performance. No bloat; every line of code serves a purpose.
  • Zero vendor lock-in. Your code, your hosting, your future.
  • Scales perfectly. You control the architecture; scale how you want.

Cons:

  • Expensive. $200K–$1M total cost of ownership.
  • Slow to launch. 6+ months to MVP.
  • High risk. You're betting on your engineering team's competence.
  • Hiring burden. You need 2–5 full-time engineers indefinitely.
  • Maintenance overhead. Everything that goes wrong, you fix.
  • Opportunity cost. Could have launched on Shopify 6 months ago.

Best for: Billion-dollar businesses (Walmart, Amazon did this), companies with unique business models, venture-backed companies with runway.

Real example: A D2C brand (direct-to-consumer) built custom ecommerce on Next.js + Node.js. Cost: $200K, 20 weeks. Year 1 revenue: $3M. By year 3, revenue: $50M. Custom features (exclusive pre-orders, collector's editions, real-time inventory gamification) were key differentiators. Shopify couldn't support these. Custom build paid for itself 10x over.

Detailed Cost Breakdown

Let's calculate TOTAL COST OF OWNERSHIP for each platform at different revenue levels.

Scenario: $500K Annual Revenue (Small Online Store)

Shopify ($39/month plan):

  • Monthly plan: $39
  • Transaction fees (2.9% + 30¢): ~$1,450/month ($17,400/year)
  • Annual apps/integrations: $1,200
  • Total Year 1: $19,968
  • Total Year 3: $19,968/year (no scaling)

WooCommerce:

  • Hosting: $30/month ($360/year)
  • Extensions/plugins: $150/month ($1,800/year)
  • Transaction fees (2.9% + 30¢): ~$1,450/month ($17,400/year)
  • Developer maintenance (part-time): $500/month ($6,000/year)
  • Total Year 1: $25,560
  • Total Year 3: $25,560/year

Why Shopify wins at this scale. No development overhead. Predictable costs.

Scenario: $5M Annual Revenue (Mid-Size Retail)

Shopify ($2,300/month plan):

  • Monthly plan: $2,300
  • Transaction fees (2.9% + 30¢): ~$14,500/month ($174,000/year)
  • Annual apps/integrations: $3,600
  • Total Year 1: $180,200
  • Total Year 3: $180,200/year

WooCommerce:

  • Hosting (scaling): $300/month ($3,600/year)
  • Extensions/plugins: $500/month ($6,000/year)
  • Transaction fees (2.9% + 30¢): ~$14,500/month ($174,000/year)
  • Developer team (full-time): $150K/year ($150,000/year)
  • Total Year 1: $333,600 (includes development)
  • Total Year 3: $183,600/year (development amortized)

Custom Build:

  • Initial development: $200K (amortized over 3 years = $66.7K/year)
  • Hosting: $500/month ($6,000/year)
  • Transaction fees: ~$14,500/month ($174,000/year)
  • Ongoing engineering team (2 devs): $300K/year
  • Total Year 1: $540,700 (includes initial build)
  • Total Year 3: $480,700/year

Why WooCommerce wins at this scale. Transaction fees kill Shopify. Custom build isn't justified yet.

Scenario: $50M Annual Revenue (Large Retailer)

Shopify (Plus tier):

  • Monthly plan: $2,300+
  • Transaction fees (2.9% + 30¢): ~$145,000/month ($1,740,000/year)
  • Annual apps/integrations: $10,000+
  • Total Year 1: $1,752,300+

WooCommerce (with scaling):

  • Hosting (enterprise): $2,000/month ($24,000/year)
  • Extensions/plugins: $1,000/month ($12,000/year)
  • Transaction fees (2.9% + 30¢): ~$145,000/month ($1,740,000/year)
  • Developer team (5 engineers): $750K/year
  • Total Year 1: $2,526,000

Custom Build:

  • Initial development: $200K (amortized = $66.7K/year)
  • Hosting (optimized): $5,000/month ($60,000/year)
  • Transaction fees (2.9% + 30¢, or better rates): ~$145,000/month ($1,740,000/year)
  • Ongoing engineering team (10 devs): $1.5M/year
  • Total Year 1: $3,366,700 (includes initial build)
  • Total Year 3: $3,300,700/year

Why WooCommerce stays ahead, but custom becomes viable. At this scale, you negotiate payment processor rates (2.2% vs 2.9%), saving $100K+/year. That's hire one developer for nearly free. Custom might be worth it if unique features justify the cost.

Decision Matrix: Choosing Your Platform

Use this matrix to choose YOUR ecommerce platform.

If your annual revenue is <$500K and you're launching soon:

→ Shopify. Simplicity and speed beat cost savings.

If your annual revenue is $500K–$5M:

→ WooCommerce. You can justify a developer ($60K/year) to manage it, and you save money on transaction fees.

If your annual revenue is >$5M:

→ WooCommerce (if it scales) or Magento (if you need enterprise features).

If you're a non-technical founder:

→ Shopify. You don't have the bandwidth to manage infrastructure.

If you have a technical team:

→ WooCommerce. They can customize and optimize. Cheaper long-term.

If you need custom features (B2B, wholesale, complex inventory):

→ Magento (if you want a platform) or Custom build (if you have budget).

If you're venture-backed with $5M+ runway:

→ Custom build. You can afford it, and unique features = competitive advantage.

If you're worried about vendor lock-in:

→ WooCommerce or Custom build. You own your data and can move anytime.

Key Features Checklist

Before choosing a platform, verify it supports these critical features:

Must-Haves (All platforms have these):

  • Product catalog management
  • Shopping cart and checkout
  • Payment processing (Stripe, PayPal, etc.)
  • Order management and tracking
  • Inventory management
  • Customer accounts

Important (Most platforms have these, but verify):

  • Email notifications (order confirmation, shipping updates)
  • Discount codes and promotions
  • Multi-currency and international shipping
  • Analytics and reporting (sales, traffic, customer behavior)
  • Mobile-responsive design
  • SSL/HTTPS and PCI compliance
  • Integration with shipping carriers (FedEx, UPS, etc.)
  • Integration with accounting software (QuickBooks, Xero)
  • Customizable email templates

Nice-to-Have (Depends on your business):

  • Subscription/recurring billing
  • Wholesale/B2B portal
  • Marketplace functionality (allow third-party sellers)
  • Wish lists and product recommendations
  • Review and rating system
  • Live chat or customer support
  • Abandoned cart recovery
  • Advanced inventory (multi-warehouse, allocation)
  • API for custom integrations
  • Headless commerce (decoupled frontend/backend)

Payment Integration & Scalability

Payment Processing

All platforms support major payment processors. Here's what you need to know:

Payment Processor Costs:

  • Stripe: 2.9% + 30¢ (standard) or 2.2% + 30¢ (custom volume agreements)
  • PayPal: 2.9% + 30¢
  • Square: 2.9% + 30¢

Platform markup:

  • Shopify adds 0% if using Shopify Payments, 2.2% if using external processors
  • WooCommerce adds 0% (you choose and integrate)
  • Magento adds 0% (you choose and integrate)
  • Custom: 0% (you choose and integrate)

Bottom line: At scale, WooCommerce, Magento, and custom builds have lower payment processing costs because you can negotiate directly with processors.

Scaling Traffic

Shopify: Built for scale. Handles traffic spikes automatically. You never worry about server capacity.

WooCommerce: Depends on hosting. On shared hosting (cheap): peaks cause slowdowns. On dedicated or cloud hosting: scales smoothly but costs more.

Magento: Built for scale. Can handle extreme traffic with proper infrastructure.

Custom: Depends on your architecture. Well-built custom systems scale; poorly-built ones don't.

Common Ecommerce Mistakes

Mistake 1: Optimizing for cost when you should optimize for launch speed.

You're not making money yet. Launching a $39/month Shopify store 6 months before your perfectly-architected WooCommerce site makes zero sense. Launch fast first.

Mistake 2: Assuming one platform will serve you forever.

You won't. Shopify to WooCommerce. WooCommerce to custom. Plan for migration. Build export capability early.

Mistake 3: Underestimating the cost of poor checkout experience.

A slow, confusing checkout increases cart abandonment by 30%+. Your platform choice affects this. Test all platforms' checkout UX before deciding.

Mistake 4: Choosing based on features you think you'll need later.

You don't need 90% of features in year 1. Choose based on what you need NOW. Add features later.

Mistake 5: Not factoring in payment processing costs.

2.9% seems small until you're at $5M revenue and paying $145K/year in fees. At scale, platform choice is really about payment processing costs.

Mistake 6: Picking WooCommerce without technical support.

WooCommerce is cheaper, but only if you have developers who can manage it. If you're non-technical and go WooCommerce, you're in pain.

FAQ

Q: Can I start on Shopify and migrate to WooCommerce later?

A: Yes, and many do. Shopify → WooCommerce is a known path. Use apps that export your products, customers, and orders to CSV. You'll need 4–8 weeks and $3K–$10K to migrate, but it's possible.

Q: Which platform has the best SEO?

A: WordPress (and WooCommerce) are SEO-native. Shopify has improved but is still behind. If SEO is critical, WooCommerce or custom build wins.

Q: What if I need to sell on multiple channels (my website, Amazon, Etsy)?

A: All platforms can integrate with multichannel management tools (Sellfy, Shopify, Inventory Lab). Inventory syncs across channels. WooCommerce and Magento integrate more flexibly; Shopify has more pre-built integrations.

Q: Is WooCommerce secure enough for storing payment data?

A: WooCommerce itself doesn't store payment data. Payment processors (Stripe, PayPal) handle that. WooCommerce just tokenizes the payment. So yes, it's secure if you use legitimate payment processors and keep WordPress updated.

Q: How long before I need to scale from my current platform?

A: Depends on growth. If you're 50% YoY growth, you'll outgrow Shopify's transaction fee structure in 2–3 years. That's when WooCommerce becomes attractive. Don't migrate early; migrate when costs justify it.

Q: Should I use Shopify or build a native app?

A: Mobile app ≠ ecommerce platform. You still need a backend ecommerce system (Shopify, WooCommerce, etc.) AND a mobile app. Build the website first; native app is second.

Conclusion

Choosing an ecommerce platform is less about picking the "best" and more about picking the best fit for YOUR constraints right now: timeline, budget, team, and scale.

Quick guidance:

  • Launching in 6 weeks, <$500K revenue: Shopify
  • 12-week timeline, $500K–$5M revenue, have developers: WooCommerce
  • Complex B2B needs, 12+ week timeline: Magento
  • Venture-backed, unique features, $5M+ budget: Custom build

The biggest mistake is overthinking this. Every platform works. Launch something. Measure. Optimize. Migrate if needed. You can't predict what you'll need in year 3. Build for what you need today.

Next step: If you're still unsure, book a 30-minute consultation. I'll walk through your specific situation—revenue, timeline, team, features—and recommend the platform that fits. Then you can execute with confidence.
