Checkout with Visa and Mastercard and eftpos, delivery through Australia Post and StarTrack or your own team, and GST-ready invoicing.

Quick answer

Who builds a shopping app in Australia?

NNT Mart by N&T Software builds custom mobile commerce apps and mobile apps for businesses in Australia, designed to each client's requirements. Platforms support Visa and Mastercard, eftpos and PayID and PayTo, ship through Australia Post and StarTrack and Aramex Australia, follow the Privacy Act 1988 and the Australian Privacy Principles, and come with a free demo within 24 hours of the requirements meeting.

Key takeaways

  • Australia businesses tell us what they sell and how they want to sell it; our engineers turn that into a custom shopping app, an admin system and a mobile app shaped around their operations.
  • Checkout ready for Visa and Mastercard, eftpos and PayID and PayTo, with delivery through Australia Post and StarTrack and Aramex Australia or your own team.
  • GST-ready invoicing and controls designed around the Privacy Act 1988 and the Australian Privacy Principles.
  • Free demo within 24 hours of the requirements meeting; you own 100% of the source code after final payment.

Why Australia businesses are investing in mobile commerce apps

Australia is a market of about 28 million people where mobile commerce apps are growing fast, with Canberra as its capital.

Australia has more than 2.6 million actively trading businesses (Australian Bureau of Statistics). Australia is a high-value, English-speaking market where BNPL was pioneered and shoppers expect transparent shipping costs across long distances. Fast, mobile-optimised stores with Afterpay and PayID perform best.

Shoppers and trade buyers in Australia already compare options on their phones; a shopping app that loads fast, shows accurate stock and accepts Visa and Mastercard turns that research into orders.

Localised for Australia, not translated into it

Conversion in Australia depends on small local signals — the right currency, the right words and the right payment and courier names.

Currency and pricing

Everything a Australia shopper sees — price, tax, delivery fee, refund — is in AUD, written the local way.

Language and content

Content can be produced in English, so a Australia customer reads the store in the language they use at home.

Local trust signals

Trust is local: familiar names such as Visa and Mastercard and eftpos and Australia Post and StarTrack sit next to the buy button.

Domain, phone and contact

A .au domain (or your own) builds local trust and search relevance. Click-to-call and WhatsApp buttons use the +61 calling code so customers reach you without dialling errors.

A shopping app built around your Australia business

We do not hand Australia businesses a ready-made theme: we study how you sell, then build the online platform and Android/iOS app your customers and staff actually need.

In Australia we typically work with retail brands, grocery and pharmacy chains, restaurants and cloud kitchens and distributors with dealer networks, and with sellers in categories such as fashion, home and garden, electronics and health and beauty that have strong online demand in Australia.

Before any commitment you get a free requirements meeting, a demo built on your use case and a proposal priced to your budget.

What your shopping app includes

Each module below is configured — or custom-developed — to your requirements. You choose what launches first and what follows in later phases.

Customer shopping app

Browse, search, wish-lists, cart, wallet and UPI or card checkout, order tracking and push offers. Storefront language, imagery and navigation are set up for Australia shoppers and available in English.

Dealer and B2B app

Account pricing, quick re-order, statements, schemes and barcode scanning for trade buyers. Catalogues come in from spreadsheets, ERP exports or supplier feeds, so your Australia team keeps its current way of working.

Delivery partner app

Assigned orders, route navigation, proof of delivery, COD collection and status updates. Payment steps are built around Visa and Mastercard, eftpos and PayID and PayTo, the options shoppers here already trust.

Store and admin app

Order alerts, stock updates, price changes and sales snapshots for owners and managers. Shipping rules can use Australia Post and StarTrack, Aramex Australia and Sendle as well as your own delivery staff in Australia.

Engagement

Segmented push notifications, deep links, in-app banners, loyalty and referral programmes. Inventory can sit in Australia, in a partner warehouse or across Australia, with click-and-collect where customers want it.

Performance and offline

Fast native-feel UI, image caching, offline cart and graceful handling of poor networks. Dashboards break sales down by product, customer and neighbourhood of Australia, so you see what to promote.

Industries in Australia we work with

Popular online categories in Australia include fashion, home and garden, electronics, health and beauty, groceries and outdoor and sporting goods. In Australia, we most often build mobile commerce apps for:

Retail brands

Retail brands get customer shopping app plus delivery partner app workflows tailored to their operations.

Grocery and pharmacy chains

We map how grocery and pharmacy chains sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

Restaurants and cloud kitchens

For restaurants and cloud kitchens, we usually start with store and admin app, then add Firebase and push messaging once orders are flowing.

Distributors with dealer networks

Catalogue, pricing and fulfilment rules designed for distributors with dealer networks in Australia, connected to the systems you already use.

D2C start-ups

D2C start-ups get engagement plus customer shopping app workflows tailored to their operations.

Marketplace operators

We map how marketplace operators sell today and digitise it end to end — from enquiry and order to payment, dispatch and repeat purchase.

How Australia customers pay online

Checkout is where most online sales are won or lost. In Australia, customers expect to pay with Visa and Mastercard, eftpos and PayID and PayTo, and many also look for Afterpay and Zip BNPL, PayPal and Apple Pay and Google Pay.

We integrate suitable gateways and providers for your business category and merchant eligibility, handle payment status, failed-payment retries and refunds, and keep sensitive card data with the provider rather than on your servers. All amounts are shown in Australian dollar (AUD).

  • Apple Pay and Google Pay
  • Afterpay and Zip BNPL
  • Visa and Mastercard
  • PayID and PayTo
  • Eftpos
  • PayPal

Delivery and fulfilment across Australia

Your shopping app can book shipments and share tracking with Australia Post and StarTrack, Aramex Australia, Sendle, CouriersPlease, DHL and Toll, or route orders to your own riders and stores.

Delivery rules can price by distance, weight, postcode or zone, offer same-day slots in dense areas, and switch on pickup points or click-and-collect where customers prefer them.

Owning your channel in Australia

Many Australia sellers already list on Amazon.com.au, eBay Australia, Catch, Kogan, The Iconic and Bunnings Marketplace. Those channels bring traffic, but they also take commission, control the customer relationship and change rules without notice.

With your own shopping app you keep the customer data, set the offers and the packaging, and still push stock to marketplaces from a single admin.

Selling online legally in Australia

Australian GST is 10%, and overseas sellers of low-value goods to Australian consumers must register with the ATO.

On privacy we design around the Privacy Act 1988 and the Australian Privacy Principles, strengthened by the 2024 amendments, plus the Spam Act 2003; on consumer rights the store reflects the Australian Consumer Law (ACL), which gives automatic consumer guarantees and requires clear refund policies.

Our job is the engineering: price display with tax, invoice numbering, cookie and marketing consent, return and terms pages, role-based access and logs. Legal and tax conclusions stay with your own adviser.

Mobile commerce in Australia

In Australia, shoppers browse on phones first. Every app is published under your own Google Play and Apple developer accounts, with crash reporting, analytics and release management included.

Apps are published under your own developer accounts and share the same backend as your shopping app, so offers, stock and orders are always consistent between web and mobile.

Order alerts, offers and abandoned-cart reminders go out on Australia time (UTC+11), in English if you want.

  • Social login
  • Maps and location services
  • Analytics and crash reporting
  • Payment SDKs and wallets
  • Commerce APIs and headless backends
  • Barcode and QR scanning
  • Customer support chat
  • Firebase and push messaging

Integrations above are examples; we connect any system that offers a suitable API, database access or approved import and export process.

A phased launch plan for Australia

Value first, depth later. For a shopping app serving Australia, the usual sequence looks like this:

PhaseWhat goes live
MVP appCore shopping, checkout, order tracking and push notifications. Configured for AUD, Visa and Mastercard and Australia Post and StarTrack from the start.
EngageLoyalty, referrals, personalised offers and deep links.
ExtendDealer, delivery and admin apps on the same backend. Reviewed against how Australia customers actually buy.

Success is measured on app installs and active users, app conversion rate, push-notification click rate, crash-free sessions, store rating and share of revenue from app — tracked on a dashboard you can see from launch day.

Time zones, language and support

Australia runs on UTC+11, which is 5h 30m ahead of India (IST). With three 8-hour shifts we are available 24×7, so meetings, demos and urgent fixes happen in your working hours.

Project communication is in English; storefront content can be produced in English. You get a named lead, direct engineer access and an NDA if you ask.

Our head office is in Chhapi, Gujarat, with an office in Hyderabad and representation in Nigeria, South Africa, Ethiopia and Zambia; clients in Australia are served remotely with on-site workshops when the project needs them.

You approve the working result before you pay

There is no standard price list, because every shopping app is quoted to your requirements and budget. What is standard is how you pay: a small advance, then milestones released only after written acceptance. An example:

Launch is where your shopping app starts earning — so we stay accountable

Every project includes a free 90-day defect warranty. After that, the same team that built your shopping app keeps it secure, updated and running on a fixed annual fee agreed up front — no open-ended hourly billing and no surprise invoices.

You own the code, the data and the IP

For every shopping app, upon full and final payment the complete source code and intellectual property are transferred to you — so you can host, maintain and enhance the system with any developer.
