Zeller vs Square: Which POS System Is Better for Small Business?

Introduction

Australian small businesses face a stark reality: card payments now account for 76% of all consumer transactions, while cash has plummeted to just 13%, according to the Reserve Bank of Australia's 2022 Consumer Payments Survey. Choosing the right EFTPOS or POS system directly affects your cash flow, daily operations, and overall cost structure.

Zeller and Square are two of the most talked-about payment solutions in Australia — but they serve very different business needs. Picking the wrong one can mean overpaying on transaction fees or missing features that matter as you grow.

Here's a direct breakdown of pricing, hardware, POS features, and payout speed — so you can pick the one that actually fits your business.

TLDR

  • Zeller charges 1.4% per transaction and bundles a free Transaction Account and Mastercard, making it the simpler, lower-cost EFTPOS option in Australia
  • Square charges 1.6% but offers more specialised POS software for restaurants and retail, plus ecommerce tools and wider hardware options
  • Zeller leads on transaction pricing and built-in banking; Square leads on software depth and online payment flexibility
  • Neither requires monthly fees or lock-in contracts
  • Specialty retailers with complex inventory or multi-location needs will likely outgrow both — purpose-built retail POS systems handle these demands better

What is Zeller?

Zeller is an Australian EFTPOS and business banking solution launched in 2021, designed to simplify payments and replace the need for a traditional business bank account, bundled into a single package. Founded in 2020 by former Square executives, Zeller holds an Australian Financial Services Licence (AFSL No. 534281) and is regulated locally.

Hardware Options

Terminal 1 ($99):

  • Built-in receipt printer
  • Basic payment processing
  • Best for mobile merchants, market stalls, and sole traders who need simple card acceptance

Terminal 2 ($199):

  • 6.5" touchscreen
  • POS Lite software built in
  • No printer (requires separate purchase)
  • Best for cafés, small retailers, and businesses needing basic product catalogues and checkout

Standout Financial Tools

Beyond the hardware, every Zeller terminal ships with a built-in suite of banking tools:

  • Free Zeller Transaction Account that receives payouts every morning
  • Linked Mastercard debit card for business spending
  • Optional savings account
  • Corporate expense cards for staff

These tools reduce admin overhead for new or unbanked businesses — useful for anyone who wants payments and banking handled in one place.

Pricing and Connectivity

  • 1.4% flat rate (lowest pay-as-you-go rate in Australia)
  • No monthly fees
  • No lock-in contracts
  • Optional SIM card ($15/month) for 4G connectivity when WiFi isn't available

Integrations

Zeller integrates directly with Xero for accounting and supports 600+ POS platforms. However, ecommerce integration is not yet available.

Who is Zeller Best For?

Zeller suits:

  • Sole traders, small retailers, cafés, mobile merchants, and market stall operators
  • Newly launched businesses that want a clean, low-cost EFTPOS setup without the complexity of a business bank account
  • Businesses processing moderate card volumes where saving 0.2% per transaction (vs Square's 1.6%) makes a measurable difference

A business processing $200,000 in card sales annually pays $2,800 with Zeller vs $3,200 with Square — a $400 yearly saving.

  • Operations scaling up over time, from a single card reader to a full register setup

Zeller vs Square: Which is Better for Your Business?

Pricing at Scale

Transaction fees matter more as your card volume grows.

Example calculation:

  • Business processing $200,000 annually in card sales
  • Zeller (1.4%): $2,800 in annual fees
  • Square (1.6%): $3,200 in annual fees
  • Annual savings with Zeller: $400

Run this calculation against your own monthly card turnover to see the real-dollar impact. For businesses processing higher volumes, the 0.2% difference compounds significantly.

POS Software Depth

For simple product catalogues and checkout, Zeller POS Lite and Square's free POS app are broadly comparable — both handle basic inventory, sales processing, and reporting.

For restaurants, appointment-based businesses, or multichannel retailers, Square's specialised POS apps offer significantly more native functionality:

  • Table management and course firing for restaurants
  • Online booking and automated reminders for service businesses
  • Advanced inventory and vendor management for retail

These features are built in, without requiring third-party integrations—giving Square the edge for complex operations.

Cash Flow and Banking

Zeller's advantage:

  • Free Transaction Account and same-morning payouts are uniquely useful for businesses without an existing business bank account
  • Corporate expense cards for staff simplify expense management
  • All-in-one financial ecosystem reduces admin overhead

Square's advantage:

  • Instant payout feature (1.5% fee) is the only option in Australia for truly same-day bank deposits
  • Better for businesses that need speed to a bank account rather than a separate business account

Online and Ecommerce

Square is the clear winner for any business selling online:

  • Built-in online store
  • Ecommerce platform integrations (Wix, OpenCart)
  • QR code ordering
  • Gift cards

Zeller's remote payment tools (invoicing, virtual terminal, payment links) handle one-off remote transactions well, but fall short for businesses with a real online sales channel.

When Both May Fall Short

Neither platform is built for the complexity that specialty retailers deal with daily. If your business is a garden centre, pet supply shop, outdoor sporting goods store, or farm market and you need:

  • Advanced inventory management (seasonal stock, variable units of measure, bulk/weight-based products)
  • Customer loyalty programs with tiered rewards
  • Multi-location support with centralised inventory and consolidated reporting
  • Robust margin reporting by category and vendor performance analytics

Both Zeller and Square will likely leave gaps. A purpose-built retail POS — like NCR Counterpoint, available through AMS Retail Solutions — is built around these workflows from the ground up, not bolted on as an afterthought.

Choose Zeller If:

  • You want the lowest transaction rate (1.4%)
  • You need a free business Transaction Account and Mastercard
  • You operate a mobile or simple retail setup
  • You don't sell online or need advanced POS features
  • You want 24/7 customer support included

Choose Square If:

  • You run a restaurant, hospitality business, or appointment-based service
  • You need specialised POS software without third-party integrations
  • You sell online or want to build an ecommerce channel
  • You need instant payouts (even at 1.5% fee)
  • You want to scale from a basic reader to a full register over time

Conclusion

Zeller and Square serve different business profiles well. Zeller suits merchants who want the lowest transaction rate, a simple checkout, and built-in banking without the overhead of extra software. Square suits those who want a single platform that scales from a card reader to a full POS ecosystem with ecommerce, loyalty, and industry-specific tools.

If neither system fully meets your needs—especially if you run a specialty retail business with complex inventory, multi-location operations, or specific reporting requirements—it may be worth exploring a dedicated retail POS solution built for the way you actually operate. For specialty retailers, systems like NCR Counterpoint offer the depth and customization that entry-level POS solutions can't match.
