6 best ecommerce platforms for Australian small business owners in 2026

Best ecommerce platforms in Australia at a glance

What should small business owners look for in an ecommerce platform in Australia

Start with the business model you already have, then compare platforms against the costs and operational requirements that will actually affect the store.

• Sales channels and inventory: If you already sell in person, check whether POS, stock and orders can stay synchronised with the online store. A DTC business selling almost entirely online will put more weight on product management, checkout, apps and international selling.
• Total cost: Compare more than the monthly subscription. Payment-processing rates, transaction fees, paid apps, hosting, plugins and developer support can all change the real cost of running the store.
• Pricing, GST and compliance: Check how the platform handles GST, customer-facing prices and payment surcharges. Under Australian Consumer Law, displayed prices must be clear and accurate and include GST and other unavoidable or pre-selected charges in the minimum total price. Card surcharges also need to follow the applicable Australian rules.
• Technical ownership: Managed platforms such as Wix, Squarespace and Shopify handle hosting and much of the infrastructure. WooCommerce gives you more control over hosting, plugins and code, but someone still has to maintain that stack.
• The next realistic stage: If B2B pricing, multiple storefronts, a larger catalogue or more complex fulfillment are already on the 12-month roadmap, include them in the decision now. If they are only hypothetical, paying for that complexity early usually adds cost without solving a current problem.

6 ecommerce platforms worth comparing for a small business in Australia

These six platforms solve different problems. The useful question is not which one has the longest feature list, but where each one saves work and where it starts creating more of it.

Shopify: best all-rounder for ecommerce founders

Shopify makes the most sense when ecommerce is the business rather than just another sales channel. Hosting, checkout, product management and payments are already connected, so you can run the core store without stitching together separate systems.

On Basic, the current Australian price is AUD $56/month, or AUD $42/month when billed annually. You get unlimited products, inventory tools, Shopify Payments, marketplace and social selling, plus 24/7 chat support. Grow becomes relevant once more people need access or card costs start to matter: it supports up to five staff accounts and lists a 1.6% + 30¢ standard online card rate, compared with 1.75% + 30¢ on Basic. Advanced lifts staff access to 15 and adds regional controls and live third-party shipping rates. These figures come from Shopify pricing.

The continuity is what makes Shopify easy to keep. A founder can run the first version of the store alone, then add staff, sales channels or international selling without moving the whole business to another platform.

The bill can change before the platform does. In recent 2026 owner discussions, positive comments often centre on not having to babysit the technical side, while complaints are more likely to focus on app subscriptions and paying extra for specialised functions. A July 2026 owner discussion also raised a useful boundary: when the website has to work as a portfolio or content property as much as a store, owners start looking harder at Squarespace or WordPress.

For an ecommerce-first founder, that is a reasonable trade: more platform, less maintenance. Shopify is harder to justify for a small catalogue where the website only needs to take occasional orders; in that case, the convenience can simply become another monthly cost.

Square Online: best for selling online and in person

Square Online is much easier to justify if a Square terminal is already sitting on your counter.

The current Australian Free plan costs AUD $0/month and charges 2.2% per online transaction. Plus costs AUD $36/month billed annually, while Premium costs AUD $99 and reduces the online processing rate to 1.9%.

The main advantage is the connection with Square POS. Online and in-person sales can draw from the same product and inventory data, which reduces the amount of manual coordination needed between channels. You can compare the current pricing and plan differences on the Square plans page.

Square Online also covers practical omnichannel needs such as pickup, local delivery and shipping. Plus adds a custom domain, more design control, pre-orders and abandoned-cart recovery, giving smaller retailers more room to improve the online store without changing their broader Square setup.

The trade-off is ecommerce depth. If the website starts carrying more of the merchandising, content, international selling or integration workload, Square can become more restrictive than a commerce-first platform.

Square is easiest to justify when physical selling remains an important part of the business and the online store needs to work alongside it. If ecommerce is expected to become the main sales channel, Shopify or WooCommerce deserves a closer comparison.

Wix: best for founders building their first store themselves

Wix makes sense when you are also the person building the website and do not want to call a developer every time the homepage, booking flow or product page needs changing.

You can build on Wix for free, but selling starts on Core. The current Australian pricing page lists Core at AUD $42/month including GST, Business at AUD $55/month and Business Elite at AUD $199/month. Light costs AUD $21/month, but it does not include payment acceptance, so it is not the relevant starting point for an ecommerce comparison. Check the live Wix plans before subscribing, as pricing can change.

Wix is most useful when the founder wants to keep making small site changes without opening a developer ticket. That can suit a consultant adding a few products, a maker with a short catalogue or a service business that needs bookings, content and checkout on the same site.

The decision changes once store operations drive requirements. Recent 2026 small-business discussions still tend to talk about Wix primarily as an all-in-one website builder. As catalogues expand or fulfilment and integrations become more complex, the question is whether Wix’s commerce tools can keep pace without adding workarounds.

That does not make Wix a weak ecommerce platform. Its main strength is giving a non-technical founder control over the wider website as well as the store. If catalogue management, fulfilment or integrations are likely to become the difficult part, test those workflows on Wix before committing.

WooCommerce: best for founders who want WordPress control

WooCommerce takes the opposite approach to a managed platform. You get more control, but you also inherit more of the decisions.

The core software is free and open source, and WooCommerce does not take a platform revenue share. That does not make the store free to run. Hosting, payment processing, extensions, themes and development all sit outside that headline price.

This trade-off works well if WordPress is already familiar territory. You choose the host, can move infrastructure if performance becomes a problem and have far more freedom over code and plugins than you get with a closed SaaS platform. WooCommerce’s hosting guidance makes the practical issue clear: an ecommerce site has to cope with checkout, catalogue requests and traffic spikes differently from a basic brochure site.

The “free” part matters less once you start adding what the store actually needs. WooCommerce notes that some free extensions move into paid tiers, while recent 2026 owner discussions still spend plenty of time on plugin combinations, conflicts, caching and performance.

Those problems are manageable, but they are yours to manage.

WooCommerce is a good fit if technical ownership already exists inside the business. If every plugin conflict or checkout change means another developer invoice, the free core quickly stops being the cheapest option.

Squarespace: best for design-led, simpler stores

Squarespace earns its place here for businesses where the website has to look polished before the catalogue gets complicated.

Its current Australian annual-billing prices start at AUD $17/month on Basic, followed by Core at AUD $28/month, Plus at AUD $49/month and Advanced at AUD $109/month. The platform also offers a 14-day free trial.

For new accounts, those Basic, Core, Plus and Advanced plans replace the old Personal, Business and Commerce labels. Basic carries a 2% Squarespace commerce transaction fee, while Core, Plus and Advanced do not. The current structure is explained in the ecommerce plans documentation.

For Australian Squarespace Payments users, domestic personal cards are currently 1.75% + AUD $0.30 on Basic and Core, 1.55% + AUD $0.30 on Plus, and 1.35% + AUD $0.30 on Advanced. Business and international cards cost more, so the lowest headline rate is not the whole payment picture. Squarespace lists those rates in its payment fees guide.

Squarespace is easiest to justify for photographers, studios, hospitality brands and small lifestyle businesses where imagery and content do much of the selling and the product range remains manageable.

Recent 2026 owner discussions point to the same limit. Owners like how quickly they can get a polished site live, but complaints start appearing around inventory, product variants and integrations once the store becomes more operationally demanding.

Squarespace works best when the store supports the brand, rather than when the store is the operational engine of the business. If B2B, complex fulfilment or a large integration stack is already on the roadmap, Squarespace is easier to rule out early.

BigCommerce: best for owners who already need more ecommerce depth

BigCommerce belongs on the shortlist once the requirements have outgrown a simple first-store brief.

Pricing changed on 1 June 2026, and the old Standard, Plus, Pro and Enterprise names are gone. BigCommerce’s Australian pricing page currently lists Core at USD $39/month or USD $29/month billed annually, Growth at USD $105/ USD $79, and Scale at USD $399/USD $299. Performance starts from USD $1,499/month on annual billing. Australian businesses are billed in USD, so the AUD cost varies with the exchange rate and any card/FX charges. The current figures are on the pricing page.

The part to model before signing up is what happens as sales rise. Core moves you up once trailing-12-month GMV passes USD $30,000, Growth goes to USD $100,000, and Scale starts with USD $33,333 in monthly GMV before a 0.9% overage applies.

BigCommerce also charges Open Payment Provider Fees of 2% on Core, 1% on Growth and 0.6% on Scale when you use providers outside its embedded-provider programme. The change is explained in its pricing update.

That is why the USD $29 annual-billing figure is a poor way to judge BigCommerce. If you already need B2B, several storefronts or more catalogue structure, the built-in depth can be useful. A small DTC brand that mostly needs products, checkout and fulfilment may simply be buying complexity early.

That pricing change is not theoretical for existing merchants. In an August 2026 merchant discussion, some BigCommerce users said their monthly costs had risen enough for them to reconsider the platform or start looking at migration. That is anecdotal rather than universal, but it is a useful reason to run your expected revenue through the GMV thresholds before committing.

BigCommerce belongs on the shortlist when you can name the requirement that needs it: B2B, multiple storefronts, deeper catalogue control or similar operational depth. If the US$29 figure is the main attraction, do the GMV maths first.

Which ecommerce platform should you actually choose

Your ecommerce platform handles the storefront and checkout, but not every finance workflow behind the business. Aspire’s expense management tools can help Australian businesses manage operating spend with multi-currency accounts, international transfers, corporate cards with spend controls, employee claims, budgets and accounting integrations such as Xero and QuickBooks. That can make it easier to manage supplier payments, team spending and reconciliation alongside the ecommerce operation without expecting the store platform to handle those finance processes.

Final take

The best ecommerce platform for an Australian small business is the one that matches the business model you already have and the next stage you can reasonably see.

Shopify is the clearest starting point for an ecommerce-first business, Square Online is strongest when online and in-person selling need to stay connected, and Wix or Squarespace make more sense for simpler website-led stores. WooCommerce suits businesses prepared to own more of the technical stack, while BigCommerce becomes more relevant when B2B, multiple storefronts or deeper catalogue requirements already exist.

Do not choose the subscription price alone. Model payment costs, apps, hosting, maintenance and the operational features you are likely to need over the next 12 months. The cheapest platform to open is not necessarily the cheapest one to run.
