Point of sale · Perth, WA
Looking for a Magento 2 POS extension in Australia? There's a better way.
Most Australian retailers searching for a Magento 2 POS extension want one thing: their online store and retail counter working as one. Mainstack POS delivers exactly that — as a fully-managed platform we build, integrate and support for you, not a plugin you have to configure and maintain yourself.
The real goal
What a Magento 2 POS extension is meant to solve
A point-of-sale extension promises to connect your storefront to your physical counter. In practice, retailers want four outcomes — and a bolt-on extension only gets you part way to each.
One inventory, online and in-store
Sell the same stock online and across the counter without overselling. Mainstack POS keeps one inventory pool synced in real time — no nightly batch, no spreadsheets.
Lower card fees
Most Magento 2 POS extensions route payments through third-party processors at 1.7–2.2%. Mainstack POS connects bank-direct via Linkly-compatible terminals, so you pay your own bank's rates.
Hardware that just works
PIN pads, receipt printers and terminals from Westpac, CBA, ANZ and NAB — configured and tested for you, not left as a DIY integration after you install an extension.
Books that reconcile themselves
Sales, refunds, customers and invoices flow into MYOB or Xero automatically — so your accounts stay current without manual exports.
Extension vs platform
A Magento 2 extension is software you maintain. Mainstack is a platform we run for you.
A Magento 2 POS extension on its own
- You install, configure and update the extension yourself
- Payment processing usually runs through third-party rates
- Terminal and hardware integration is left to you
- Compatibility breaks when the core or other extensions update
- Support means raising a ticket and waiting
Mainstack POS, fully managed
- We build, configure and maintain the whole platform
- Bank-direct EFTPOS at your own bank's rates via Linkly
- Terminals and hardware configured and tested for you
- Built on enterprise-grade Adobe Commerce architecture and kept patched
- Local Perth team that picks up the phone in your timezone
If you're already running Adobe Commerce, we can migrate your store onto a fully-supported Mainstack platform — catalogue, customers, orders and integrations included.
Also need your accounts in sync? See our Magento 2 MYOB extension alternative.
Since 1 October 2026, retailers can no longer surcharge eftpos, Mastercard or Visa payments, so the rate you pay on those cards now comes straight off your margin. See what the surcharge ban costs retailers →
Already on Magento 2? Not everything in the core waits for someone to switch it on — Advanced Reporting enables itself at install and, once signed up, builds a nightly archive of customer and order data. See what Magento 2 Advanced Reporting sends →
Common questions
Magento 2 POS extension FAQs
Do I need a Magento 2 POS extension to sell in-store?
Not necessarily. A Magento 2 POS extension bolts a point-of-sale onto your store, but you still own the configuration, updates, hardware integration and reconciliation. Mainstack POS delivers the same outcome as a fully-managed service — online and in-store on one platform with one inventory pool, built and supported by us from Perth.
What is the best Magento 2 POS extension for Australian retailers?
Most off-the-shelf options are built for generic markets and route card payments at 1.7–2.2%. Mainstack POS is built for Australian retailers: bank-direct EFTPOS via Linkly-compatible terminals (Westpac, CBA, ANZ, NAB and more) at your own bank's rates, plus real-time inventory and MYOB or Xero sync.
How is Mainstack different from installing a Magento 2 POS extension?
An extension is software you install and maintain. Mainstack is a managed commerce platform: we configure your catalogue, payments, terminals and reporting, then keep it patched and supported — a connected online + in-store + back-office stack instead of a plugin you have to make work yourself.
Can you migrate my existing Magento 2 or Adobe Commerce store?
Yes. We work with retailers on enterprise-grade Adobe Commerce architecture and migrate existing stores onto a fully-supported Mainstack platform — catalogue, customers, orders and integrations included. Book a consult and we'll scope it for your business.
Custom development
Just need a custom Magento 2 extension built?
Not everyone needs to replace their stack — sometimes you just need something built. We also develop custom Magento 2 and Adobe Commerce extensions: bespoke modules, third-party and API integrations, payment and POS connections, and fixes or upgrades to existing extensions — built to your requirements and supported from Perth.
