Point of sale · Perth, WA
Looking for a Magento 2 POS extension? There's a better way.
Most 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.

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.
