How we calculate this
  • Estimated cost: each provider’s published prices and rates applied to the inputs you set above (such as volume, team size, or invoices), plus any fixed monthly fees.
  • Providers with an incomplete cost (shown as “+ processing” or “+ payroll”) and quote-only providers are never ranked as the cheapest while a complete-cost option exists.
  • These are estimates. Published rates can change and your final pricing depends on your business, so confirm current pricing with the provider before switching.

A retail POS has a different job from a hospitality one: less about tables and tickets, more about stock control, fast checkout and keeping inventory accurate across what can be thousands of products and several locations. The right system depends on how much inventory complexity you have and whether you also sell online. Below are our ranked picks, then a live calculator to cost each at your card volume.

How we chose

Retailers weigh POS on inventory capability and total cost. We ranked on how well the system manages stock (from a small shop to a multi-store catalogue), the processing rate and any software fee, whether it syncs online and in-store for omnichannel sellers, and fit for specialty trades. Pricing is live from our database in Australian dollars.

Match the system to your inventory needs

This is the key decision. A small shop with a modest range is well served by Square or Zeller: free software, low rates, and enough inventory tooling to cope. A retailer with hundreds or thousands of SKUs, variants, supplier orders and multiple stores needs a dedicated platform, where Lightspeed Retail's depth pays off despite its monthly fee. And if you sell online as well as in-store, omnichannel sync (Shopify) matters more than raw inventory depth.

Watch the total cost, not just the rate

As with hospitality, free software at a slightly higher rate can beat a paid platform with a lower rate, until volume or inventory complexity tips the balance. Work out software plus processing together at your real takings, which the calculator above does. For a small shop, free software usually wins; for a high-volume or inventory-heavy retailer, the capability of a paid platform earns its fee.

The verdict

For most Australian retailers, Square is the best all-rounder: free software, a competitive rate and fast setup. Choose Lightspeed Retail if you need serious inventory and multi-store control, Zeller if you want the lowest flat rate and a bundled business account, Shopify if you sell online and in-store, and Tower Systems if you run a specialty shop in one of its trades. Use the calculator above to cost each at your volume.
