Shopify or a custom build?

Start here

The platform is not the decision.

The useful question is not which platform is better. It is whether the way you sell fits the shape Shopify assumes: a product, some variants, a cart, a checkout, a shipping rate. That shape covers most of retail, and when it fits, fighting it is expensive.

When it does not fit — and you usually know the moment you try to explain your pricing to someone — every workaround becomes an app, and every app is a monthly bill and one more thing that can break at checkout.

Shopify

What you are actually buying.

You are buying a checkout somebody else keeps working. That is the part people underrate. Payments, fraud screening, PCI scope, tax rules, hosting, uptime, security patches — all of it stops being your problem, permanently.

• A checkout that converts and is maintained for you
• Payments and fraud handling out of the box
• An app for nearly any missing feature
• Staff who can run the store without a developer
• Nothing to patch, ever

The cost of that is a monthly floor you cannot go below, limited control over the checkout itself unless you are on the top plan, and a data model you have to work within rather than around.

Custom

What you are actually taking on.

A custom build gives you the whole stack: your data model, your checkout logic, your integrations, no per-app rent. It also gives you back everything Shopify was quietly doing — updates, security, uptime, payment compliance.

That is a fair trade for some businesses and a bad one for others. It is fair when the thing you sell genuinely does not fit a cart: configured products, quoted pricing, B2B accounts with negotiated rates, hire periods, licences, anything where the price depends on who is asking. It is a bad trade when the honest answer is that you just wanted it to look different.

The part quotes hide

Two cost curves, not two prices.

A build price is a single number, so it is what everyone compares. It is the wrong comparison. Shopify starts lower and keeps charging — plan, apps, transaction fees if you use an outside gateway — and that line rises as you add capability. A custom build starts higher and flattens, but it never reaches zero, because maintenance is real work whether or not anyone budgets for it.

The two curves cross somewhere, and where they cross depends almost entirely on your app bill. Some stores pay more each month in apps than the gap between the two builds would have been over two years. Others buy a custom build to escape app fees and never come close to earning back the maintenance.

If you want the numbers side of this, we set them out separately in what a Shopify website actually costs.

A test that works

Describe one order out loud.

Take a real order you fulfilled last week and write down every step, from the customer deciding to buy through to you being paid and them having the goods. Do not simplify it. Include the exceptions, because the exceptions are where platforms break.

Now read it back. If every step maps onto a product, a variant, a cart and a shipping rate, use Shopify and put the money you saved into photography and stock. If two or more steps need a paragraph of explanation, that is the shape of the thing a custom build is for — and it is also, usefully, the specification.

One more thing

The choice is not permanent.

Starting on Shopify and moving later is a normal, sensible path, and plenty of good businesses have taken it. Products, customers and orders all export cleanly. What does not export is anything an app has taken custody of, so if a migration is somewhere in your future, be deliberate about which apps you let hold your data.

Going custom on day one, for a product nobody has bought yet, is the version of this that goes wrong most often.
