Custom E-commerce vs Shopify: Which Is Right for Your Business in 2026?

You're ready to sell online. But should you use Shopify, build a custom e-commerce platform, or go with another solution entirely?

This is one of the most important decisions in your e-commerce journey because switching platforms later is expensive and disruptive. We've helped businesses make this choice hundreds of times — some starting with Shopify and later migrating to custom, others going custom from day one.

Here's the honest, complete comparison to help you decide.

The Quick Answer

Choose Shopify if:

• You're selling physical products with standard e-commerce needs
• Your budget is under $20,000 for the initial build
• You want to launch in under 4 weeks
• You don't need deep customization of the checkout or business logic
• Your team doesn't include developers

Choose custom e-commerce if:

• You have complex business logic (B2B pricing, subscriptions, multi-vendor marketplace)
• You need complete control over the customer experience
• Your budget is $30,000+ and you're building for long-term scale
• You have unique requirements that Shopify apps can't handle
• You want to own your platform and data entirely

Cost Comparison

Shopify Costs

| Cost Category | Shopify Basic | Shopify Advanced | Shopify Plus | |---|---|---|---| | Monthly subscription | $39/mo | $399/mo | $2,300+/mo | | Transaction fees | 2.9% + 30¢ | 2.6% + 30¢ | 2.15% + 30¢ | | Theme (premium) | $180 – $350 | $180 – $350 | Custom ($5K – $25K) | | Apps (avg 5-10) | $100 – $500/mo | $100 – $500/mo | $200 – $1,000/mo | | Custom development | $0 – $10,000 | $5,000 – $30,000 | $15,000 – $100,000 | | Year 1 total | $3,000 – $18,000 | $10,000 – $45,000 | $50,000 – $200,000 |

Custom E-commerce Costs

| Cost Category | Simple Store | Medium Store | Complex Platform | |---|---|---|---| | Development | $20,000 – $50,000 | $50,000 – $120,000 | $120,000 – $300,000 | | Design | $5,000 – $15,000 | $15,000 – $30,000 | $30,000 – $60,000 | | Hosting | $50 – $300/mo | $200 – $800/mo | $500 – $3,000/mo | | Payment processing | 2.9% + 30¢ | 2.9% + 30¢ | Negotiable at volume | | Maintenance | $1,000 – $3,000/mo | $3,000 – $8,000/mo | $8,000 – $20,000/mo | | Year 1 total | $40,000 – $90,000 | $100,000 – $220,000 | $250,000 – $600,000 |

Key insight: Shopify is significantly cheaper for year 1. But the total cost of ownership over 3-5 years can converge, especially as transaction fees and app costs compound with revenue growth.

The Hidden Cost of Shopify at Scale

Many businesses don't account for these costs:

• Transaction fees add up: At $1M annual revenue, Shopify's transaction fees cost $29,000 – $31,500. At $10M, that's $290,000 – $315,000.
• App costs compound: The average Shopify store uses 6-8 paid apps. At $50-$200/month each, that's $3,600 – $19,200/year.
• Custom development on Shopify is expensive: Liquid templating language is harder to work with than modern frameworks. Developers charge premium rates for Shopify customization.
• Migration costs: If you outgrow Shopify and need to migrate, expect $50,000 – $200,000 in migration costs.

When Shopify Is the Right Choice

1. You're Starting Out

If you're validating a product idea or launching your first e-commerce store, Shopify lets you go live in days, not months. The lower upfront investment means less risk.

2. Standard D2C Physical Products

If you're selling T-shirts, coffee, skincare products, or similar physical goods with standard pricing, Shopify handles this beautifully out of the box.

3. Your Team Isn't Technical

Shopify's admin interface is excellent. Non-technical team members can manage products, orders, and content without developer help.

4. You Need to Launch Fast

Shopify stores can launch in 1-4 weeks. Custom e-commerce takes 2-6 months.

5. Your Annual Revenue Is Under $2M

Below this threshold, Shopify's total cost of ownership is almost always lower than custom.

When Custom E-commerce Is the Right Choice

1. Complex Business Logic

If your pricing depends on customer type, volume, contracts, or custom quotes — Shopify's rigid pricing model will frustrate you. Custom lets you build exactly the pricing engine you need.

2. Marketplace or Multi-Vendor

Building a marketplace (like Etsy or Amazon) where multiple sellers list products requires custom architecture. Shopify's multi-vendor solutions are limited and expensive.

3. Subscription-First Business

While Shopify supports subscriptions via apps, a subscription-first business (like a SaaS product with physical fulfillment) often needs custom subscription management that's deeply integrated into the core experience.

4. B2B E-commerce

B2B commerce has fundamentally different needs: customer-specific pricing, quote-to-order workflows, approval chains, net payment terms, bulk ordering, and integration with ERP systems. Custom platforms handle these natively.

5. Unique Customer Experience

If your competitive advantage depends on a unique shopping experience — custom product configurators, AR try-on, interactive sizing tools — custom development gives you the freedom to innovate.

6. Performance Is Critical

Every 100ms of page load time costs approximately 1% in conversion rate. Custom e-commerce with modern frameworks like Next.js can achieve sub-second page loads that Shopify (loaded with apps) struggles to match.

7. You're Scaling Past $5M Annual Revenue

At higher revenue levels, Shopify's transaction fees and app costs become significant. Custom platforms have lower marginal costs as you scale.

Technology Stack for Custom E-commerce in 2026

Our recommended stack for custom e-commerce:

Frontend: Next.js with React

The Hybrid Approach: Headless Shopify

There's a middle ground: use Shopify as your backend (product management, inventory, checkout) but build a custom frontend.

Pros:

• Shopify handles the operational complexity
• Custom frontend gives you full design freedom
• Better performance than standard Shopify themes
• Access to Shopify's app ecosystem for backend features

Cons:

• Still limited by Shopify's API and data model
• More expensive than standard Shopify (development + subscription)
• Checkout customization is still limited
• You're still paying Shopify's transaction fees

Best for: Businesses that want a premium frontend experience but don't need custom business logic.

Decision Framework

Ask yourself these questions:

1. Is your business model standard e-commerce? → Shopify
2. Do you need custom pricing, workflows, or business logic? → Custom
3. Is your budget under $30K? → Shopify
4. Do you need to launch in under 4 weeks? → Shopify
5. Is your annual revenue over $5M? → Consider custom (or headless Shopify)
6. Are you building a marketplace? → Custom
7. Is checkout customization critical? → Custom
8. Do you have a development team? → Either (lean toward custom for long-term value)
