Somebody quoted you Shopify. Here's what you'd actually be renting.

A store you rent, not software you install

The useful distinction is who owns the machinery. WordPress is software you install on hosting you pay for, and from there it's yours to look after. Shopify is the other arrangement. You get an account, and everything under it is theirs: the servers, the database, the checkout, the patching.

What you control is the front. The theme, written in Shopify's own template language and yours to edit or replace outright. The catalogue. The admin where orders and customers live. And the app store, which is how anything the platform doesn't do itself gets added.

One company owns the whole stack. That fact sits behind the good news and the bad news below.

What it takes off you is the part nobody wants

Selling online has an interesting half and a tedious half. The interesting half is design, photography, the product page. The tedious half is what overruns.

Taking a card without the number ever touching a machine you're responsible for. Working out the tax on an order going somewhere you've never shipped. Deciding whether the 3am order billed in one country and shipped to another is real. Holding one honest stock count while three channels sell the same item. Staying up on the day your ad finally works.

All of that is the default state of a Shopify account. Card details go to Shopify and its payment processor rather than to anything you run, so the card industry's security rules ask far less of you than they would if you handled the number yourself. Tax at checkout uses rates the platform maintains, though registering and filing stays with you. Flagged orders still need a human.

That's the purchase. Most of the rest follows.

The checkout isn't yours, and that's the trade

The thing new store owners push hardest against is the checkout. You can brand it and add things at defined points, a field here, a message there, a rule about which shipping options appear. You can't rebuild it.

That isn't Shopify being precious. The checkout is where the card data sits, where the fraud scoring runs and where the compliance lives. Every store sharing one hardened checkout is why your own exposure is small. Open that page to a few hundred thousand separate builders and it's safe for nobody.

It's also where a returning shopper may already have their payment details saved, which is worth more than most of what a bespoke checkout would buy.

Shopify has tightened this over the years rather than loosened it. Even its largest merchants moved off editing the checkout template and onto a fixed set of official extension points. If you need the checkout to behave in a way the platform hasn't anticipated, raise it in week one.

Apps are the extensibility, and where the cost collects

Anything the platform doesn't do itself, an app does. Subscriptions, bundles, product configurators, loyalty, reviews, shipping rules. Whatever the odd requirement is, something in the app store already does it and you could have it running this afternoon.

That comes with two bills. The first is money: apps are mostly monthly, per store, indefinitely, so fifteen of them is a recurring line nobody put in the original number. The second is speed. Many add their own code to the storefront, and it runs in your customer's browser before the page settles.

Uninstalling doesn't always undo that. App code left behind in a theme is common, so a store can carry the weight of something it stopped paying for years ago.

Running cost has three parts: the plan, a rate on every card transaction, and the apps. There's also an extra fee per transaction if you take payment through a provider other than Shopify's own. Plans and rates change and vary by country, so read the current terms on the day you decide.

Where it stops is your selling model, not your size

The assumption is that you outgrow Shopify by getting big. That's rarely what happens. Very large stores run on it. What breaks the fit is a way of selling that doesn't look like a cart.

A cart makes four quiet assumptions: the price is known before the customer asks, the thing is countable, one seller gets paid, and it finishes in one step. Loosen any of them and you're working against the grain. Quoted work, configured products priced by calculation, rentals billed against dates, money owed to several sellers.

Apps reach some of these, and every app is a dependency. The question isn't whether Shopify can be made to do it, because with enough apps it usually can. It's whether the result is one you'd have chosen if somebody had shown it to you first.

Who has to be around after launch

Shopify removes the maintenance that needs a technical person reachable at night. Nobody patches a server, nobody restores a database, nobody renews a certificate.

What it doesn't remove is retail. Somebody keeps the stock counts honest, because the platform will cheerfully sell what you don't have. Somebody registers for sales tax where you're obliged to, since the platform calculates it and doesn't file it. Somebody works the flagged orders and answers the chargebacks.

And somebody owns the theme. Themes are code, and the person who can change one isn't the person who publishes a product. Go a year without that person and a small change costs more than it should. It's a lighter commitment than a self-hosted site, and most of it lands on operations rather than on anyone technical.
