Shopify vs Custom E-commerce in Australia: Which Should You Build On?
8 September 2026
Shopify is the right choice for most Australian stores, and we say that as a team that builds custom e-commerce. The question is not which is better, it is at what point Shopify's constraints and fees start costing more than a custom build would.
Where Shopify wins
Speed to launch, a massive app ecosystem, PCI-compliant checkout you never have to think about, and a support team. For a standard catalogue with standard shipping and one currency, it is hard to beat, and a themed Shopify store can be live for A$3,000 to A$6,000.
If you have not yet proven demand, start here. Custom software around a product line you might pivot is wasted money.
Where it starts to hurt
Transaction fees if you do not use Shopify Payments, 0.5 to 2 percent on every order, plus apps that each add A$20 to A$200 a month. A store that needs eight apps to do what it needs is often paying A$500+ a month before ad spend, and each app is a point of failure at checkout.
Then there are the models Shopify was not built for: B2B pricing tiers and account-based ordering, bilingual catalogues with genuinely different content per market, products that require configuration or provisioning (eSIMs, subscriptions with usage, memberships), and checkouts that need to talk to your own operations systems.
What a custom storefront costs and when it pays back
A custom e-commerce build by a lean senior team lands between A$6,000 and A$15,000 in Australia, with hosting under A$50 a month and no per-order platform fee. Compare that against three years of Shopify plan, apps, and transaction fees at your projected volume. Stores doing more than A$300,000 a year or with non-standard models usually see the custom option come out ahead.
The eSIM commerce platform in our case studies is a good example: bilingual, 200+ countries, automated provisioning after payment. That is not a Shopify job, and forcing it into one would have cost more in apps and workarounds than the build.
A middle path that often makes sense
Keep Shopify as the catalogue and payment engine and build a custom e-commerce layer for the piece it cannot handle: a B2B portal, a configurator, a bilingual storefront. You keep the checkout you trust and only pay to build what is actually different about your business.
