Shopify vs Custom E-Commerce: Which Should You Build in 2026?

This is the first question almost every e-commerce project starts with, and it's often resolved too quickly. "Everyone uses Shopify" is not an answer. Neither is "custom is better." The right call depends on your margins, your checkout requirements, and where you'll be in three years — not just where you are today.

Here's how we actually think through this decision.

What Shopify Actually Costs

The $29/month Basic plan is not what you'll be paying at any meaningful scale. Let's build the real number.

Subscription: Shopify Basic starts at $29/month. Advanced (needed for lower transaction fees and better reporting) is $299/month. Shopify Plus (needed for checkout customisation, B2B features, and volume) is $2,300/month minimum, often more.

Transaction fees: Unless you use Shopify Payments (which is only available in select countries and comes with its own limitations), Shopify charges an additional fee on every transaction: 2% on Basic, 1% on Shopify, 0.5% on Advanced. On $1M annual revenue, that's $5,000–$20,000 per year going to Shopify before your payment processor takes their cut.

Apps: The Shopify app ecosystem solves real problems — but at a cost. Subscriptions, loyalty programs, advanced reviews, upsells, bundles, B2B features, custom shipping rules, advanced search — each of these is typically a $30–$200/month app. Real Shopify stores at scale often run 15–25 apps, adding $500–$2,000/month in app fees alone.

Total realistic cost for a mid-scale Shopify store: $800–$3,500/month in platform fees before you've paid for design, marketing, or fulfilment.

Where Shopify Limits You

Shopify has made significant investments in flexibility, but there are structural limits that don't go away at any price point.

Checkout customisation: Even on Shopify Plus, the checkout is a controlled environment. You can modify it with Checkout Extensions, but you cannot fully rebuild it. If your business model requires a non-standard checkout — configure-price-quote, multi-step onboarding, B2B purchase approval flows, custom pricing by account — Shopify will fight you.

Data ownership: Your customer and order data lives in Shopify's infrastructure. You can export it, but you don't own the schema, you don't control the backup cadence, and if Shopify terminates your account (rare but it happens, usually to merchants in categories they've decided to restrict), your data situation is suddenly very complicated.

Feature restrictions: Shopify has famously banned or restricted categories of products over the years. If your business operates in any category that's even adjacent to something Shopify finds uncomfortable — firearms accessories, adult products, certain supplements, cannabis (jurisdiction-dependent) — you're building on uncertain ground.

Performance: Shopify's Liquid templating engine and their infrastructure impose performance ceilings. You can get fast Shopify stores, but there are limits to what you can do with server-side rendering, edge delivery, and custom caching strategies that Next.js gives you natively.

What Headless Shopify Is (and Isn't)

Headless Shopify means using Shopify's Storefront API as a backend commerce engine while building a completely custom frontend. You get Shopify's product management, checkout, and payment processing, paired with a custom React/Next.js frontend you control entirely.

It's a real option and a legitimate middle ground for some businesses. But it's worth being clear about what you get and what you don't.

You still pay Shopify's fees. You still operate within Shopify's data environment. Checkout customisation is better than standard Shopify but still constrained by the Storefront API's limits. You're building significant custom infrastructure to maintain.

Headless Shopify makes sense if you're already deeply invested in the Shopify ecosystem (existing product data, existing 3PL integrations, existing Shopify Payments setup) and need a better frontend. It doesn't make sense if you're starting fresh and the primary driver is performance or checkout flexibility — at that point, a fully custom build gives you more control for similar investment.

When Custom Wins

There are four situations where custom development is clearly the right call:

1. Your margins can't absorb Shopify's fees at scale. If you're doing $500K+ annually in revenue and operating on margins below 30%, platform fees and app subscriptions are a meaningful cost line. Custom development has a higher upfront cost but a lower ongoing cost — and the break-even point is closer than most people expect.

2. You need a checkout flow that a platform won't support. Subscriptions with complex tier logic, B2B account management with purchase approval, configure-price-quote, multi-product bundles with custom pricing rules — these either don't exist on Shopify or require Plus plus significant custom development anyway.

3. You have existing systems that need real integration. Connecting Shopify to an existing ERP, WMS, or CRM ranges from annoying to genuinely expensive, depending on the systems involved. A custom build can treat those integrations as first-class requirements from day one.

4. You're building a platform, not just a store. Marketplaces, multi-vendor platforms, branded wholesale portals — these are custom projects. There's no version of Shopify that handles them.

When Shopify Is Still the Right Call

Shopify is the right answer in more situations than many custom developers will admit.

If you're pre-revenue or early-stage, the speed of getting a Shopify store live (days, not months) and testing whether your product actually sells is worth the platform constraints. Validate first, optimise later.

If your product catalogue is simple, your checkout is standard, and your integrations are covered by existing apps, you may never hit the walls that make Shopify painful. A huge portion of e-commerce businesses operate perfectly well on the platform.

If your team doesn't have technical resources for ongoing custom development, Shopify's managed infrastructure is a real advantage. You're not thinking about server maintenance, database backups, or dependency updates.

The Honest Recommendation

Don't let anyone make this decision for you based on their preferences. Build the real cost model for both options over a three-year horizon. Include platform fees, app fees, transaction fees, development costs, and ongoing maintenance. The number will tell you more than any opinion will.

Frequently Asked Questions

Can I migrate from Shopify to a custom store later?

Yes, but it's rarely as smooth as it sounds. Product data migrates cleanly; customer accounts, order history, and any app-specific features don't. If you already know you'll need custom functionality within 12–18 months, it's usually cheaper to build custom from the start.

Does Shopify work for B2B or wholesale?

Shopify Plus (the enterprise tier) has B2B features including wholesale pricing and company accounts. For complex B2B scenarios — custom contract pricing, approval workflows, multi-location ordering — a custom solution is typically a better fit.

What does a custom e-commerce store cost compared to Shopify?

Shopify runs $29–$299/month with apps adding $100–$500/month. A custom store requires a higher upfront investment ($15,000–$60,000+) but eliminates recurring platform fees and app stacking. The break-even point depends on how long you plan to run the store and how many custom requirements you have.
