Shopify vs. Custom E-Commerce Website: Which Should Your Business Choose?

We build custom e-commerce and we still tell most enquiries to use Shopify. For a business selling forty products with standard shipping, a custom store is an expensive way to reinvent something excellent that already exists for $39 a month.

But Shopify's economics are volume-based, and its constraints are structural. Both become relevant at a fairly predictable point. Here is where the line sits.

Head to head

The real cost of Shopify

The subscription is the smallest part. Apps and transaction fees are what most owners underestimate, and both scale with success.

When custom genuinely wins

Revenue is the crude signal. These are the specific situations where custom is the right call regardless of what you are turning over.

• Unusual product logic

  Configurable products, quantity-break pricing, made-to-order, rental periods, subscriptions with irregular rules. Shopify apps can approximate these; they rarely fit properly.

• Deep system integration

  Live inventory from a warehouse system, pricing from an ERP, orders into accounting. Shopify's APIs are good but you are always working around someone else's data model.

• High volume, thin margin

  At $2m of revenue on 8% margin, a 1% platform cost is over 12% of your profit. That is the arithmetic that moves businesses off hosted platforms.

• B2B and trade pricing

  Customer-specific price lists, credit terms, approval workflows, purchase orders. Genuinely painful to bolt onto a consumer platform.

• Checkout is your battleground

  If a one-point conversion improvement is worth six figures, you need full control of checkout — which below Shopify Plus you do not have.

• Data ownership matters

  Regulated industries, or businesses where the customer relationship and its data are the actual asset being built.

The migration question

Moving off Shopify is a real project, not a switch. Plan for it properly and it is unremarkable; improvise and you will lose rankings and orders.

1. Export products, customers and order history early — Shopify's exports are good but incomplete for some app data.
2. Map every existing product and collection URL to its new equivalent, and 301 redirect all of them.
3. Run both systems in parallel for a short window if you can, with the new one behind a password.
4. Migrate reviews deliberately — they are usually held by an app, not by Shopify, and they are hard to recreate.
5. Do not migrate in Q4. Ever.

Frequently asked questions

• Is Shopify cheaper than a custom e-commerce website?

  Below roughly $250,000 a year in online revenue, comfortably yes. Between $250,000 and $700,000 the two converge once app subscriptions are counted. Above roughly $700,000 a custom store is usually cheaper over five years.

• What are Shopify's hidden costs?

  App subscriptions are the big one — most stores run $100 to $600 a month in apps. Add the 0.5 to 2 percent transaction fee if you use an external payment gateway, plus theme customisation and any developer work. The plan fee is typically the smallest line.

• Can I move my Shopify store to a custom website?

  Yes. Products, customers and order history export cleanly. The theme and app functionality do not, so treat it as a rebuild, map every product and collection URL to a 301 redirect, and migrate reviews deliberately since they usually live in an app.

• Is a custom store safe for taking payments?

  Yes, when built correctly. Card details go directly to Stripe, PayPal or a similar processor and never touch your server, which keeps PCI scope minimal. The security responsibility is real but manageable and well understood.

• How long does a custom e-commerce build take?

  Six to twelve weeks for most stores, scaling with catalogue size and how many systems it must integrate with. B2B platforms with pricing rules and approval workflows typically take longer.

• What about WooCommerce as a middle option?

  It is a legitimate middle ground — no per-sale platform fee and more flexibility than Shopify, but it inherits WordPress's plugin and maintenance overhead. It suits businesses already comfortable running WordPress; it is rarely the right reason to adopt WordPress.
