What You Get With Our eCommerce Development Services

🛒

Which eCommerce platform is right for our Australian online store?

We recommend Shopify for most B2C retail stores (fastest to launch, easiest to manage), WooCommerce for businesses already on WordPress needing a tightly integrated store, and custom headless eCommerce for high-volume or complex B2B scenarios requiring pricing rules, ERP integration, or custom checkout flows that Shopify and WooCommerce can't accommodate.

💳

Which Australian payment methods can customers use at checkout?

We integrate Stripe, Braintree, eWay, Afterpay, Zip, Latitude Pay, PayPal, and Apple Pay / Google Pay. Afterpay integration is standard on all Australian eCommerce projects — it typically increases average order value by 20–30% for eligible product categories.

📦

How does shipping and fulfilment work for Australian orders?

We integrate with Australia Post (eParcel, StarTrack), Sendle, Shippit, and Shipbob — including real-time rate calculations at checkout, automated label generation, tracking number pushback to customers, and same-day dispatch workflow integration with your 3PL or warehouse system.

📊

How is the online store connected to our accounting software?

Xero and MYOB integrations sync orders, payments, and refunds in real time — creating sales invoices, allocating GST, and reconciling payments automatically. This eliminates manual data entry between your store and accounting software and ensures accurate BAS reporting for your accountant.

📈

How is the store built to rank in Google Shopping and organic search?

Product pages include structured data markup (Product, Offer, AggregateRating), optimised title and meta templates, canonical URL handling for filtered pages, XML sitemap including products, and Google Merchant Centre feed export for Shopping ads. Collection and category pages are built with SEO-optimised architecture.

🔒

How is customer payment and personal data kept secure on the store?

No card data is stored on our servers — all payment processing uses tokenised integrations (Stripe Elements, Braintree Hosted Fields). PCI DSS compliance is achieved via the hosted payment provider. SSL, HTTPS enforcement, CSP headers, and automated vulnerability scanning protect customer data throughout the shopping experience.

🌏

Can the online store sell to customers outside Australia?

Yes — multi-currency display and checkout (AUD, USD, GBP, NZD), international shipping rate calculation, localised tax handling (including GST for AU and NZ customers), and international payment methods are all configurable. Geo-based currency detection shows the appropriate currency automatically based on the visitor's location.

📱

Will mobile shoppers have a great experience on our online store?

Mobile-first design is standard — Australian online shopping is over 65% mobile. We build touch-optimised product galleries, one-tap checkout flows, persistent cart across sessions, and progressive image loading for fast mobile page speeds. Checkout is optimised to minimise form fields on mobile without reducing the data captured.

eCommerce Development FAQs

Common questions about our ecommerce development services.

Ask Us Anything →
How much does eCommerce website development cost in Australia?
eCommerce development in Australia starts from AUD $20,000 for a Shopify or WooCommerce store with standard integrations. A custom headless eCommerce platform or complex B2B trade portal typically ranges from AUD $60,000 to $200,000+. OpenMalo provides a fixed-price quote after a free discovery session based on your specific requirements.
Which eCommerce platform should we use — Shopify, WooCommerce, or a custom build?
Shopify is best for most B2C retailers: it's fully managed (no server maintenance), has an excellent app ecosystem, and is the fastest to launch. WooCommerce is ideal if you're already on WordPress and need tight CMS integration. A custom or headless build makes sense for high-volume stores with complex B2B pricing rules, custom checkout flows, or ERP integrations that Shopify and WooCommerce can't support. We help you make the right choice during the discovery phase.
Can you integrate Afterpay and Zip into our online store?
Yes — Afterpay and Zip integration is standard on all Australian eCommerce projects. We implement on-site messaging showing Afterpay/Zip instalment amounts on product pages and in the cart, and configure the checkout flow for a frictionless BNPL experience. This typically increases average order value by 20–30% for eligible categories.
How do you connect the store to Australia Post for shipping rates?
We integrate the Australia Post API for real-time shipping rate calculations at checkout (eParcel, Express Post, StarTrack). Customers see live rates based on their postcode and order weight/dimensions. We also integrate automated label generation and tracking number emails — with the option to connect to Shippit for multi-carrier shipping management.
Can the online store sync orders with Xero automatically?
Yes — Xero integration creates sales invoices from orders in real time, allocates GST correctly, applies payment records, and reconciles refunds — all without manual data entry. MYOB integration is also available. These integrations save hours of bookkeeping work per week and ensure your BAS reporting is always accurate.
How do you migrate our product catalogue from our old platform?
We export products, variants, pricing, images, meta data, and stock levels from your old platform and import into the new one with full validation. For Magento or BigCommerce migrations, we also migrate customer accounts and order history so your team doesn't lose access to historical data. A parallel testing period confirms migration accuracy before the old store is retired.
How is the online store optimised for Google search and Shopping ads?
Product pages include JSON-LD Product schema (for rich results), optimised title tag templates, canonical URLs for filtered category pages, XML sitemap with product URLs, and a Google Merchant Centre product feed export for Shopping ads. We also configure GA4 eCommerce tracking so you can measure revenue, ROAS, and conversion rates by traffic source from day one.
Can we sell wholesale (B2B) and retail (B2C) from the same store?
Yes — we build B2B/B2C hybrid stores with account-based wholesale pricing, trade application workflows, credit account management, minimum order quantities, and purchase order checkout — all within a single platform. Wholesale customers log in to see their negotiated prices; retail customers see standard pricing without any friction.
How do we manage inventory across our physical store and online store?
We integrate eCommerce inventory with your point-of-sale (POS) system (Lightspeed, Square, Vend) or ERP so stock levels update in real time across channels. Overselling is prevented by safety stock buffers; low stock alerts trigger reorder workflows. For businesses with complex inventory, our custom ERP integration handles multi-location and consignment stock scenarios.
What ongoing support do you provide for eCommerce stores?
We offer eCommerce maintenance plans from AUD $1,500/month covering platform updates, security patches, integration maintenance, new product imports, conversion rate analysis, and ad-hoc development. We also offer CRO retainers focused on improving conversion rates through A/B testing, checkout optimisation, and email automation setup.
