E-commerce Build Cost: Shopify vs Custom Development
Shopify or a custom build? One is fast and low-cost to start, the other fits exactly and scales. Here's what e-commerce really costs and how to choose for your store.
- E-commerce cost ranges from a low-cost Shopify store to a fully custom platform — the right choice depends on your scale, complexity and how unique your needs are.
- Shopify and similar platforms are fast and cheap to launch but charge ongoing fees and limit deep customisation; custom costs more but fits exactly and removes per-sale platform fees.
- Most stores should start on a platform and only go custom when scale, complex logic or integrations justify it.
"How much does an online store cost?" depends almost entirely on one decision: a hosted platform like Shopify, or a custom build. One gets you selling quickly for a low upfront cost; the other fits your business exactly and scales without platform limits. This guide breaks down what drives e-commerce cost, the ongoing fees to plan for, and how to choose.
Shopify vs custom at a glance
| Shopify / platform | Custom build | |
|---|---|---|
| Upfront cost | Low | Higher |
| Time to launch | Fast | Longer |
| Customisation | Limited to the platform | Whatever you need |
| Ongoing fees | Subscription + transaction fees | Hosting + maintenance |
| Best for | Standard stores, fast launch | Scale, complex logic, deep integration |
What drives e-commerce cost
- Design & branding — a templated theme is far cheaper than a bespoke, branded experience.
- Catalogue & complexity — product variants, configurators and complex pricing add work.
- Integrations — payments, ERP, inventory, shipping and marketing tools.
- Custom features — subscriptions, B2B pricing, marketplaces or unusual checkout flows.
- Scale & performance — high-traffic, high-SKU stores need more engineering.
Platform fees are easy to overlook. On a hosted platform, transaction and app fees scale with revenue — a real cost to weigh against a custom build you own.
The ongoing costs
Whichever route you choose, budget beyond launch. Hosted platforms charge subscription fees, per-transaction fees, and often paid apps for features that don't come built in. A custom store has hosting, maintenance and the cost of building features yourself — but no platform cut on every sale. Over time and at scale, that difference adds up and often tips the maths toward custom.
How to choose
Most businesses should start on a platform like Shopify: it's fast, cheap and proven, and lets you validate the store before investing heavily. Move toward custom (or a headless build) when you outgrow the platform — high volume, complex B2B or subscription logic, deep ERP integration, or platform fees that have grown into a serious cost. The right answer often changes as you scale, so it's a decision to revisit, not a one-time bet.

Weigh the ongoing fees, not just the upfront price — that's where the real comparison lives.
Frequently asked questions
How much does it cost to build an e-commerce website?
It ranges widely — from a low-cost Shopify store to a fully custom platform. The cost depends on design, catalogue complexity, integrations, custom features and scale. Hosted platforms are cheap to start; custom costs more upfront but removes per-sale platform fees.
Is Shopify cheaper than a custom e-commerce build?
Cheaper to start, yes. But Shopify charges subscription and per-transaction fees plus paid apps, which scale with revenue. A custom store costs more upfront but has no platform cut on sales — so at higher volume the total cost can favour custom.
When should I move from Shopify to a custom store?
When you outgrow the platform — high traffic and SKU counts, complex B2B or subscription logic, deep ERP or inventory integration, or platform and app fees that have grown into a significant cost. Many businesses start on a platform and go custom (or headless) as they scale.
What drives the cost of an online store?
Design and branding, catalogue complexity (variants, configurators, pricing), integrations (payments, ERP, shipping, marketing), custom features like subscriptions or B2B pricing, and the scale and performance you need to support.
What ongoing costs come with an e-commerce store?
On a platform: subscription fees, per-transaction fees and paid apps. On a custom store: hosting, maintenance and building features yourself. Either way, budget beyond launch — and weigh platform fees that scale with revenue against a custom stack you own.
What is a headless e-commerce build?
Headless separates the storefront (what shoppers see) from the commerce engine behind it, connected via APIs. It offers the design and performance freedom of custom with the option to reuse proven commerce backends — a popular middle ground for stores outgrowing a standard platform.
