We get this question every week: "Should I be on Shopify, or should I build something custom?"

The answer is annoyingly nuanced. Both can be right. Both can be very wrong. Here's how to actually decide.

When Shopify Is the Right Answer

Shopify is genuinely the best default for most online stores. Don't let anyone — including us — tell you otherwise without a real reason.

Stick with Shopify if:

You sell physical products with standard shipping
Your catalog is under ~5,000 SKUs without exotic configuration logic
You don't need deep custom integrations with internal systems
You'd rather pay $79/month + transaction fees than maintain code
You have one storefront, one currency, one tax model (more or less)

For 80% of e-commerce businesses, Shopify is faster, cheaper, and better than anything custom we could build. The platform team has thought about your problem longer than we have.

When Shopify Starts Hurting

The cracks tend to show up in four places:

1. Custom product configuration. When customers need to configure something complex — pick from 30 sizes, choose engraving, upload a file, build a bundle, get a real-time quote — Shopify's "Variants" model fights you. You end up duct-taping with apps that each cost $30/month and break in subtle ways.

2. B2B / wholesale logic. Custom price lists per customer, NET 30 terms, quote requests, account approvals. Shopify Plus has some of this; the gap between "some" and "what your business actually does" gets expensive fast.

3. Heavy backend integrations. ERP systems, custom inventory, manufacturing flows, EDI partners. The more your e-commerce site is part of a system, the less an off-the-shelf platform fits.

4. App stack hell. When you're paying for 12+ apps every month — each with their own quirks, support tickets, and update cycles — you're paying for complexity without owning it. At a certain spend, custom is cheaper.

The Math That Usually Decides

A useful rule of thumb:

Under $500K/year in sales: Stay on Shopify. The ROI on custom isn't there yet.
$500K – $2M/year: Depends entirely on what you're doing. Most stay on Shopify Plus. Some benefit from a custom frontend (headless) on top of Shopify's backend.
$2M+ / year with complex operations: Custom or hybrid usually wins, both in margin and in flexibility.

Notice the bias toward staying on Shopify. There are exceptions, but most "we need custom" requests we get could be solved on Shopify with better setup.

The Headless Middle Ground

There's a third option most people don't know about: headless Shopify. You keep Shopify's backend (orders, inventory, payments, admin) but rebuild the storefront as a custom site — usually on Next.js or Hydrogen.

You get:

Shopify's platform reliability
Custom design and UX
Real performance (Core Web Vitals 90+)
Flexibility on the customer-facing side

You don't get:

Cheap. Headless is real engineering, not a theme swap.
The Shopify theme ecosystem (you're building UI from scratch)

For larger Shopify stores hitting performance or design ceilings, this is the right move 80% of the time.

The Wrong Reasons to Switch

Don't migrate off Shopify because:

A developer tells you you've "outgrown" it (often we're the ones being outgrown)
You want to save the $79/month subscription (you'll spend that on a single dev hour)
A competitor has a custom site and looks fancier (their revenue per visitor probably isn't what you think)

Migrate when the platform itself is preventing your business from doing something it needs to do — not when it's just slightly inconvenient.

The Bottom Line

Shopify is the right answer for most stores. Custom is the right answer for the specific stores it's right for. Headless is the underrated middle.
