Most US brands asking "Shopify or custom?" are really asking two different questions at once: what does this cost me today, and what does it cost me when I am five times bigger? The answers point in opposite directions, which is why the decision feels harder than it is.
Here is the honest version, including the case for the option we do not sell.
The case for Shopify, stated properly
Shopify is genuinely excellent and the right answer for a large share of US e-commerce businesses. It handles the parts that are boring and hard: PCI-compliant checkout, tax calculation across US states, fraud screening, payment processing, inventory, shipping labels, and an app for almost anything else.
Choose Shopify when:
- You are early and need to be selling in weeks, not months.
- Your catalogue and fulfilment are conventional — physical products, standard variants, standard shipping.
- You do not have engineering resources and do not want any.
- Your differentiation is the product and the brand, not the buying experience.
- The apps in the ecosystem already do what you need.
Anyone telling a first-time founder with a simple catalogue to build custom is selling hours, not advice.
Where Shopify starts costing you
The platform fee is the smallest part of the real number. What actually accumulates:
- Transaction fees if you use a payment provider other than Shopify's own — a real cost that scales directly with success.
- Apps. The subscription list grows quietly: subscriptions, reviews, bundles, upsells, loyalty, email, page builder, search. Many stores end up paying hundreds a month, and each app also ships JavaScript that slows the storefront.
- Theme constraints. Anything genuinely unusual becomes a fight with the theme or a paid custom-development job on top of the platform fee.
- Speed. A stack of apps plus a heavy theme makes Core Web Vitals hard to pass, which costs both ranking and conversion — see what page speed costs.
- Structural limits. Complex B2B pricing, quote flows, configurable products, unusual subscription logic, ERP integration — all doable, none comfortable.
When custom actually wins
Custom means a store built on a modern framework — in our case Next.js — with a commerce backend, either headless Shopify or a dedicated commerce API, and a storefront you fully control.
It is the right call when:
- The buying experience is the differentiator — configurators, quote builders, made-to-order, complex bundles, guided selling.
- You have real B2B requirements — customer-specific pricing, net terms, purchase orders, approval workflows, tiered accounts.
- Speed is a competitive weapon, particularly for content-heavy stores that depend on organic traffic.
- You are paying more in app subscriptions and workarounds than a build would amortise to.
- You need deep integration with an ERP, a 3PL, or systems that have opinions of their own.
Note the middle path many brands land on: headless — keep Shopify for checkout, payments and admin (the genuinely hard, regulated parts) and build a custom storefront in front of it. You get platform reliability and a storefront you control, and you can move incrementally.
The honest cost comparison over three years
Do not compare a build price to a monthly fee — compare total cost over the horizon you actually plan for.
Shopify path: platform subscription + transaction fees on every order + app subscriptions + theme + any custom development. Low to start, and it scales with revenue in a way that is invisible until you total it.
Custom path: a larger one-time build, then hosting (modest) and maintenance. Higher on day one, flat afterwards, and no per-order tax.
Our US e-commerce builds start at $1,249 — see the US e-commerce cost guide for what each tier includes and what US agencies typically charge for equivalent scope, which is usually $15,000–$50,000. Add up your last twelve months of app subscriptions and transaction fees before you decide the build is the expensive option.
Things that are true regardless of platform
Platform choice matters less than these, and brands routinely get the decision right and the fundamentals wrong:
- Mobile speed. Most US e-commerce traffic is mobile. Every second of load time costs conversions.
- Checkout friction. Guest checkout, Apple Pay and Google Pay, address autocomplete, and shipping costs shown before the final step. Surprise shipping cost is the single most common reason US shoppers abandon a cart.
- Real product photography, multiple angles, in use, with scale references.
- Reviews on product pages. They convert, they generate content, and they answer objections you did not know existed.
- Clear returns policy. American shoppers check it before buying, especially from a brand they do not know.
- Product schema markup, so your prices and ratings appear in search results.
- Email and SMS lists. The only marketing channels you own outright. Everything else is rented.
How to decide in one afternoon
- List every app you pay for, monthly, plus transaction fees for the last twelve months. That is your true platform cost.
- Write down the three things you wish your store could do and cannot. Be specific.
- Check whether those three are theme limitations (fixable cheaply) or platform limitations (not).
- Run your storefront through PageSpeed Insights on mobile and look at the field data.
- If the answer to 3 is "platform" and the cost in 1 is meaningful, get a custom or headless quote. If not, stay put and spend the money on traffic instead.
That last line is genuine advice. Plenty of brands would earn more from spending the rebuild budget on SEO or product video than on a new platform.
Frequently asked questions
Is Shopify bad for SEO?
No — Shopify's SEO fundamentals are sound. The problems come from heavy themes, app-injected scripts and the platform's fixed URL structures. A well-built Shopify store ranks fine; a store with 25 apps and a bloated theme struggles, and that is a store problem rather than a platform problem.
What is headless commerce, in plain terms?
You keep a commerce platform for checkout, payments, inventory and admin, and build your own storefront in front of it. You get the reliability of the platform's regulated parts with full control over speed and experience. It is more work than a theme and much less work than building checkout yourself.
When is WooCommerce the right answer?
When you already run a content-heavy WordPress site, your catalogue is modest, and you have someone who maintains it. It is genuinely cheap to start and genuinely expensive in maintenance and security attention as it grows. Our WordPress vs Next.js comparison covers the trade-off.
Can I migrate off Shopify later?
Yes — products, customers and orders export cleanly. What does not move is the app-specific data and any customisation embedded in the theme. Migration is a real project, which is an argument for choosing deliberately rather than an argument against ever moving.
How much should a US brand pay for an e-commerce site?
US agencies commonly quote $15,000–$50,000 for a custom build, and a decent Shopify theme setup runs a few thousand. Our custom e-commerce builds start at $1,249 — the cost guide explains exactly what sits in each tier and why the gap exists.
The short answer
If you are under a few hundred orders a month with a conventional catalogue, use Shopify and spend your money on demand. If apps and transaction fees have become a real line item, or the buying experience is your differentiator, price a headless or custom build — the payback is usually shorter than owners expect.
