Ecommerce Website Development Cost in 2026: Shopify vs Custom
What online stores really cost to build — platform fees, development price bands, and when custom beats Shopify.
Get a Free QuoteEcommerce development cost is confusing because you are paying on two axes at once: the build cost (design and development) and the platform cost (subscription fees, transaction fees, app fees) that compounds every month you trade. A store that looks cheap to launch can be expensive to run, and vice versa. This guide lays out realistic 2026 price bands for Shopify, WooCommerce, and custom-built stores, and explains which route fits which business.
These numbers come from stores we have actually scoped and built — not theoretical calculators.
Shopify Development Cost Breakdown
A professionally customised Shopify store — premium theme adapted to your brand, product setup, payment and shipping configuration, essential apps — typically costs $3,000 to $10,000. A fully custom Shopify design with bespoke sections, custom functionality via apps or Liquid work, and conversion-optimised product pages runs $10,000 to $25,000. On top of the build, budget the platform reality: $39-$399/month for standard plans, app subscriptions that commonly add $100-$500/month, and transaction fees if you do not use Shopify Payments.
Shopify Plus — required for serious checkout customisation, B2B features, and high-volume automation — starts around $2,300/month. Many growing merchants are surprised by this cliff: the moment you need what Plus offers, your platform bill jumps by an order of magnitude.
WooCommerce and Open-Source Store Costs
WooCommerce stores typically cost $5,000 to $30,000 to build professionally, with no platform subscription — but hosting must be more robust than a standard WordPress site ($30-$300/month), and premium plugins for shipping, subscriptions, or B2B pricing add up. WooCommerce trades Shopify's convenience for control: you own everything, but you also maintain everything, and poorly maintained WooCommerce stores are a common source of security and performance problems.
When a Custom Ecommerce Build Is Worth $20,000+
Custom ecommerce — typically a Next.js storefront with a headless commerce backend — makes sense when your business model does not fit platform assumptions: complex B2B pricing tiers, configurable products, marketplace dynamics, subscription logic that plugins handle badly, or checkout flows you need full control over. Builds start around $20,000 for a headless storefront on an existing commerce engine and reach $100,000+ for fully bespoke platforms.
The economics flip at scale. Platform fees, app stacks, and transaction percentages grow with revenue; custom infrastructure costs stay comparatively flat. A store doing $2M+ annually on Shopify Plus with a heavy app stack often spends more per year on the platform than a custom build would have cost — which is why replatforming is common at that revenue level.
The Hidden Costs Most Ecommerce Quotes Leave Out
Product data preparation is the most underestimated line item: photography, descriptions, variants, and category structure routinely consume more time than development on catalogue-heavy stores. Also commonly missing from quotes: payment gateway setup and compliance, shipping rate configuration and carrier integrations, tax handling across regions, email flows (abandoned cart, post-purchase), and analytics setup. Ask any agency quoting you whether these are included — the cheap quote usually excludes them.
How to Keep Ecommerce Development Costs Down
Launch with a constrained catalogue and a proven theme or design system rather than full custom design on day one; validate demand before investing in bespoke everything. Choose your platform for where you will be in two years, not where you are today — replatforming costs far more than choosing correctly upfront. And be ruthless about apps: every $30/month app is $360/year forever, and app bloat is the silent killer of Shopify margins.
Frequently Asked Questions
How much does an ecommerce website cost in 2026?
A professionally built Shopify store: $3,000-$25,000 plus monthly platform and app fees. WooCommerce: $5,000-$30,000 plus hosting. Custom headless ecommerce: $20,000-$100,000+ with minimal ongoing platform fees. The right tier depends on catalogue complexity and revenue scale.
Is Shopify or a custom store cheaper long-term?
Below roughly $500k-$1M annual revenue, Shopify is usually cheaper overall. Above that, platform fees, app stacks, and transaction percentages often exceed what custom infrastructure costs — which is when merchants replatform to headless or custom builds.
What monthly costs should I expect running a Shopify store?
Plan subscription ($39-$399, or ~$2,300 for Plus), apps (commonly $100-$500/month), transaction fees if not using Shopify Payments, email marketing tools, and theme/app maintenance. A realistic all-in floor for a serious store is $200-$800/month before advertising.
How long does ecommerce development take?
A customised Shopify store: 3-8 weeks. WooCommerce: 4-10 weeks. Custom headless builds: 10-20 weeks. Product data readiness is usually the schedule risk, not development.
Can you migrate my existing store without losing sales or SEO?
Yes — with proper URL redirect mapping, metadata preservation, and a staged cutover, stores migrate without meaningful ranking loss. We plan migrations so the old store trades until the moment the new one takes over.
