How Much Does an E-commerce Website Cost in Australia in 2026

An e-commerce website in Australia in 2026 costs roughly $0–$1,200/yr for a Shopify or Wix store you set up yourself, $3,000–$8,000 from a freelancer doing a theme reskin, $12,000–$35,000 from a small studio doing a real Shopify or BigCommerce build, $45,000–$120,000+ for a Shopify Plus agency project, and $80,000–$250,000+ for a custom headless build on something like Medusa or a Next.js + Sanity + Stripe stack. The price gap isn't really about pretty pages — it's about how many products, how custom the checkout, and whether you own the code or rent the platform.

Most "how much does an online store cost in Australia" articles are SEO landfill written to capture a contact form. The honest version requires you to know four things: what Shopify actually charges once you stack the apps, what your payment processor takes per transaction, what isn't in the agency proposal, and at what point Shopify's per-transaction fees overtake what a custom build would cost. So here's the working.

The price brackets that actually exist for AU e-commerce

If an AU agency quotes under $8,000 for a "custom Shopify build", what they're selling is a theme reskin. That can be the right call — but call it what it is. If anyone quotes above $120,000 for fewer than 500 SKUs and no B2B portal, ask what's actually being built. The interesting bracket for most Australian businesses doing real e-commerce is $12,000–$35,000 with a small studio: real custom theme work, proper integrations, no overhead funding a CBD office.

What Shopify actually costs once you stack the apps

The headline Shopify number everyone quotes is the platform fee. As of 2026 in AUD that's roughly:

• Shopify Basic — $39/month
• Shopify (Standard) — $105/month
• Shopify Advanced — $399/month
• Shopify Plus — from ~$3,000/month AUD (USD $2,000+, billed annually)

That's the platform number. It is not what your Shopify store costs you per month. The real monthly cost is platform + apps + transaction fees + your theme licence amortised. A representative mid-tier AU Shopify store running ~500 orders/month looks like:

• Shopify Standard plan: $105/mo
• Klaviyo (email + SMS, ~10k contacts): $220/mo
• A paid theme amortised over 2 years: $15/mo
• Reviews app (Judge.me or Yotpo): $25–$120/mo
• Subscription app (Recharge or Bold): $95–$250/mo if you sell subscriptions
• Shipping app (Shippit or Starshipit): $60–$190/mo
• Inventory or ERP connector (Xero, Cin7, Unleashed): $50–$240/mo
• Page builder (PageFly, GemPages) if your theme can't do landing pages: $40–$120/mo
• Returns portal (Loop, Aftership): $60–$300/mo

Realistic stack total: $650–$1,500/month before you sell a single product. That's $7,800–$18,000/year in software alone. Shopify themselves publish their app cost methodology in their App Store, and the numbers above are conservative.

Payment processing — the line item nobody adds up

Every dollar that flows through your store has a slice taken before it lands in your bank account. AU rates as of 2026:

• Shopify Payments (powered by Stripe) — 1.7% + $0.30 domestic, 3.4% + $0.30 international, on Shopify Standard. 1.4% + $0.30 on Advanced. 1.0% + $0.30 on Plus.
• Stripe direct (custom build) — 1.75% + $0.30 domestic, 2.9% + $0.30 international. See Stripe's AU pricing.
• Shop Pay accelerated checkout — adds nothing in fees, lifts conversion 5–15%.
• Afterpay — 4–6% + $0.30 per transaction (you absorb it; the customer doesn't).
• Zip Pay — 4% + $0.15.
• PayPal AU — 2.6% + $0.30 domestic, higher cross-border.
• Apple Pay / Google Pay — no extra fee, processed through whichever gateway you use.

If you use a payment gateway that isn't Shopify Payments, Shopify charges an additional 2% on Basic, 1% on Standard, 0.5% on Advanced. This is the line item that catches Australian merchants out. Plug Stripe direct or eWAY into Shopify and you're effectively double-billed. On $1M GMV at Standard, that 1% surcharge is $10,000/year you didn't see in the platform fee.

Realistic blended processing cost on an AU Shopify store with healthy Afterpay usage (~20% of orders): 2.4–3.2% of GMV. On $500k/year that's $12,000–$16,000/year flowing out of the business. None of it shows up in an agency proposal.

The 5-year total cost of ownership, honestly

Here's the math the proposal never includes — a real comparison over five years for an AU SMB doing roughly $750k/year in online revenue.

The headline says Shopify is $92k cheaper. The headline is lying — three lines are missing. One: the custom build doesn't need re-skinning every two years; the Shopify path almost always does. Two: the custom processing rate is lower because there's no Shopify-Payments surcharge for using a non-Shopify gateway. Three: at $5M+ GMV the per-percent-of-conversion difference between a hand-built checkout and a Shopify default starts to dwarf the platform fee delta. A 0.4% lift in conversion on $750k/year is $3,000/year. On $5M it's $20,000/year. By year 3 of the example above the custom path is typically the cheaper of the two on cost-per-order, not just on absolute dollars.

The break-even isn't a single number. It depends on GMV, AOV, conversion lift and how much customisation you actually need. As a rough rule for AU brands in 2026: under $1.5M/year GMV Shopify usually wins on TCO, between $1.5M and $5M it's a coin flip that gets decided by how much custom logic you need at checkout, and above $5M custom or headless almost always wins.

The platforms worth comparing, briefly

There are five platforms most AU e-commerce builds shortlist in 2026. Pick the one that fits the business — not the one your agency happens to specialise in.

• Shopify — the default. Best when you want to be live fast, your catalogue is under ~5,000 SKUs, and you don't have weird checkout logic. Pays a tax in app costs and processing. Theme is in Liquid; harder to do something visually distinctive without paying for it.
• BigCommerce — Shopify's quieter cousin. Better at B2B and multi-currency out of the box, fewer apps required for similar functionality, no Shopify-Payments surcharge. Smaller AU partner ecosystem.
• WooCommerce — WordPress plugin. Cheap to start, painful to scale. We'd actively steer most Australian merchants away in 2026 — performance, security and update burden have all aged badly.
• Magento / Adobe Commerce — enterprise. Real engineering, real licence fees, real ongoing costs. Only makes sense above ~$10M/year.
• Medusa / Saleor — open-source, headless. Pair with a Next.js front-end and Stripe for payments. Total ownership of the codebase, no per-seat fees, no app store rent. Most expensive to build, cheapest to own at scale.

When Shopify is the right call

We'll tell you when you don't need a custom build. Shopify (or BigCommerce) is the right answer when:

• You're under $1.5M/year GMV and need to be live in under two months.
• You have under ~3,000 SKUs and a standard catalogue structure.
• Your checkout flow is standard — products, variants, cart, address, pay, ship. No quote-based pricing, no configurators, no B2B account hierarchies.
• You actually use the app ecosystem — Klaviyo, Judge.me, Recharge, Shippit — and the fees are worth it for not building those features from scratch.
• You don't need to do anything aesthetically distinctive enough that a Shopify theme can't get you there.

If that's you, save the budget. A $22k Shopify build from a small AU studio with a real custom Liquid theme will pay for itself fast.

When custom or headless wins

A custom or headless build pays for itself when:

• You're above ~$3M/year GMV and the processing surcharge / app fees are now measurable line items.
• Your checkout has non-standard logic — B2B portals, quote-based pricing, configurable products, subscription bundling, multi-step approval workflows.
• Performance materially affects revenue — paid traffic, mobile-heavy, AOV-sensitive. A custom Next.js storefront with proper caching ships pages in 200–400ms; the same Shopify store ships in 1.4–3.2s. Google's Core Web Vitals guidance is unambiguous on what that does to ranking and conversion.
• You want integrations Shopify can't do natively — direct ERP sync with Cin7 or Unleashed, custom warehouse logic, deep CRM integration, GraphQL-fed personalisation.
• Brand distinctiveness is the moat — D2C brands competing on storytelling, premium positioning, editorial content. A template-shaped storefront actively hurts a premium brand in the way it didn't five years ago.
• You're planning to be in market 10+ years and the compounding subscription cost has started to matter.

The dangerous middle is roughly $1.5M–$3M GMV — too big to feel happy with a $22k Shopify build, too small to comfortably justify $95k for headless. The honest answer there is usually a custom Shopify build on Standard now, with a planned headless migration when GMV crosses $4M. Stop trying to skip that step.

Integrations — what gets quietly bolted on later

Half the cost of an Australian e-commerce build is integrations. A proper proposal lists them; a thin one doesn't. The integrations most AU merchants need within year one:

• Accounting — Xero or MYOB sync. Apps like A2X ($30–$120/mo) or Cin7 do this. Without it, end-of-month is a manual import nightmare.
• Email and SMS — Klaviyo is the standard. Mailchimp is fine at the smallest scale. Budget $150–$600/mo by month 6.
• Shipping — Shippit, Starshipit, or direct AusPost / Sendle / DHL APIs. $40–$200/mo and saves about an hour per 10 orders in printing labels.
• Inventory — Cin7, Unleashed, DEAR / Cin7 Core. Only matters past ~$500k/year or when you sell across more than one channel.
• Reviews — Judge.me, Okendo, Yotpo. Real impact on conversion (5–12% lift in our audits when implemented properly).
• Help desk — Gorgias, Zendesk, Re:amaze. Budget $80–$300/mo once order volume passes 200/month.
• Subscriptions — Recharge or Bold for Shopify. Custom-built into a headless stack. If subscription is your business model, this single integration drives more cost than anything else.

Add all of those and your "Shopify Basic at $39/month" store is realistically a $1,200–$2,400/month monthly software bill by the end of year one. That's not Shopify's fault — every platform has this. But it's the number you should be quoting yourself when you compare paths.

The hidden costs nobody puts in the e-commerce proposal

Same hidden-cost rule as any web project, just steeper because every fee compounds with order volume.

• Transaction fees — covered above, easily $10k–$40k/year on a healthy AU SMB store.
• Apps that become essential after launch — page builders, popups, upsell apps, reviews. Budget another $200–$500/mo in apps that weren't in the original spec.
• Theme refresh every 2–3 years — Shopify themes age fast. Most agencies plan a refresh inside year three. A hand-coded headless build typically holds up 5–7 years.
• Custom dev hours after launch — Liquid theme changes, app conflict fixes, checkout extension work. AU Shopify dev rates are $160–$240/hr (freelancer), $220–$340/hr (small studio), $350–$600/hr (Shopify Plus agency).
• Product photography and content — almost never included. Budget $4,000–$15,000 for a real product shoot in Australia.
• PCI compliance and security — bundled by Shopify, your problem on a custom build. Budget $1,500–$4,000/year for the right tooling and an annual review.
• Lock-in cost on exit — the deeper you go on Shopify-specific features (metaobjects, custom checkout extensions, Shopify Flow), the harder it gets to leave. We covered this whole pattern in the hidden cost of website platform lock-in.

Six questions to ask before you sign an e-commerce proposal

Copy these directly into your next meeting:

1. "Custom Liquid theme, theme reskin, or page-builder?" A "Shopify build" can mean any of three things. Make them say which.
2. "What apps are required for this to work, and what's the monthly cost?" Then ask which ones are optional and which are load-bearing.
3. "What's the processing rate, including the Shopify Payments surcharge if we use Stripe?" This question alone is worth its weight in saved fees.
4. "Who handles app conflicts after launch, and what's the hourly rate?" Apps fight each other. Someone has to referee.
5. "What does the path to headless look like if we outgrow Shopify?" A good answer means they've thought about it. A bad answer means they haven't.
6. "What's in the proposal but not actually built — and what's built but not in the proposal?" This question makes good agencies nod, and bad ones reach for the marketing deck.

The honest call for AU e-commerce in 2026

Online stores in Australia cost between $1,000/year (DIY Shopify with a free theme) and $250,000+ (custom headless on Plus-tier traffic). For most AU SMBs doing $200k–$1.5M/year online, a real $15,000–$30,000 custom Shopify build from a small studio is the right answer — fast, well-built, low ongoing cost beyond the unavoidable Shopify tax. For brands above $3M/year, a planned migration to headless usually saves money inside three years and removes a category of platform-shaped risk.

Don't pay $25k for a theme reskin marketed as custom. Don't pay $95k for a headless build that should have been a Shopify project. And actually do the 5-year math before you sign — most proposals quietly omit the apps stack, the processing fees, and the next refresh.

If you've already built a Shopify store and you suspect it's leaking conversions, run a free 30-second audit — we'll send a 10-point report on your store within 48 hours, no pitch, keep the audit either way. If you're scoping a build now, see how we approach custom web design and decide whether a hand-coded studio is the right shape of partner.
