POSApt, Square, Zeller POS Lite, SumUp and Loyverse are among the cheapest POS systems available in Australia in 2026. However, the cheapest POS system is not always the one with the lowest monthly fee. Merchant service fees, hardware costs, online ordering expenses and software upgrades can all affect the total amount you spend each year.
Many business owners focus only on software pricing when comparing POS systems. While free POS software certainly helps reduce startup costs, transaction fees often become the biggest ongoing expense. A business processing hundreds of thousands of dollars in card payments each year may spend far more on merchant fees than software subscriptions.
The best POS system is therefore not necessarily the cheapest on paper. The best value comes from balancing software costs, transaction fees, hardware expenses and business requirements.
In this guide, we compare five affordable POS systems used by Australian cafés, restaurants, takeaway shops, retailers and service businesses.
How Much Does A POS System Cost In Australia?
Understanding where POS costs come from will help you compare providers more accurately.
Software Costs
POS software can range from free to more than $150 per month.
Typical pricing includes:
- Free POS software
- Basic plans between $20 and $50 per month
- Hospitality plans between $50 and $100 per month
- Advanced retail and multi-site plans exceeding $100 per month
The software fee is often the most visible cost but not necessarily the largest.
Hardware Costs
Most businesses require hardware to operate efficiently.
Common equipment includes:
- POS terminal
- EFTPOS machine
- Receipt printer
- Cash drawer
- Barcode scanner
- Kitchen printer
- Kitchen display system
A small retail store may spend only a few hundred dollars while a larger hospitality venue may invest several thousand dollars.
Payment Processing Costs
Merchant fees can become the biggest expense over time.
For example:
| Annual Card Sales | 1.4% Merchant Fee | 1.6% Merchant Fee |
| $250,000 | $3,500 | $4,000 |
| $500,000 | $7,000 | $8,000 |
| $1,000,000 | $14,000 | $16,000 |
Even a small difference in transaction fees can have a significant impact on profitability.
Additional Costs
Businesses should also consider:
- Online ordering
- Loyalty programs
- Staff management
- Accounting integrations
- Delivery integrations
- Additional registers
These expenses often become more important as businesses grow.
Why Free POS Systems Are Not Always The Cheapest
The word “free” attracts attention but it does not always mean lower overall costs.
Transaction Fees Matter
A free POS system may recover costs through payment processing fees.
Businesses processing large volumes of card payments should carefully compare merchant rates rather than focusing only on software costs.
Add-On Features Can Increase Costs
Many providers charge additional fees for:
- Loyalty programs
- Employee management
- Advanced reporting
- Inventory management
- Online ordering
What begins as a free POS system can become considerably more expensive over time.
Growth Changes The Equation
A POS system that works well for a startup may become less cost-effective once additional staff, locations or sales channels are introduced.
This is why total ownership cost is often more important than monthly software fees.
How We Ranked The Cheapest POS Systems
Choosing the cheapest POS system is not as simple as comparing monthly subscription prices. To create this list, we looked at the total cost of ownership and considered the expenses businesses are likely to face over the short and long term.
Monthly Software Costs
The first factor we considered was the monthly software subscription.
Some POS providers offer free software while others charge a monthly fee for access to their platform. We compared entry-level plans suitable for Australian small businesses, including cafés, restaurants, takeaway shops, retailers and service businesses.
A low monthly fee can help reduce startup costs, but it should not be viewed in isolation. A POS system with a higher monthly fee may still provide better overall value if it includes important features that would otherwise require additional subscriptions.
Merchant Service Fees
Merchant service fees are often the largest ongoing expense for businesses accepting card payments.
Even a small difference in transaction fees can have a significant impact on annual costs. For example, a business processing $500,000 in card sales each year could pay thousands of dollars more depending on the merchant rate.
We considered whether providers use fixed transaction fees, offer competitive rates or provide flexibility for businesses to negotiate rates through approved payment partners.
Hardware Costs
Most businesses require hardware to operate efficiently.
We reviewed the typical costs associated with:
- POS terminals
- EFTPOS machines
- Receipt printers
- Cash drawers
- Barcode scanners
- Kitchen printers
- Kitchen display systems
Some POS providers require proprietary hardware while others allow businesses to choose from a wider range of compatible devices. Lower hardware costs can make a significant difference for new businesses.
Support Fees
Technical support can be an overlooked expense when comparing POS systems.
Some POS providers charge additional monthly fees for support packages, premium assistance or after-hours support. Others bundle support into their software pricing.
We considered whether support was included as part of the standard subscription and whether businesses are likely to face extra charges when assistance is required.
For example, some providers such as POSApt include Australian-based support without charging separate support fees, while other providers may charge additional fees depending on the level of assistance required.
Hidden Costs
Many POS systems appear affordable initially but become more expensive once additional features are added.
We considered costs associated with:
- Additional registers
- Loyalty programs
- Staff management
- Online ordering
- Accounting integrations
- Ecommerce integrations
- Multi-location management
These expenses can significantly increase the total cost of ownership over time.
Long-Term Value
A POS system that is cheap today may not remain affordable as a business grows.
We looked at how well each provider supports business growth without dramatically increasing costs. This included evaluating scalability, additional feature pricing, payment flexibility and whether businesses are likely to outgrow the platform.
Our goal was to identify POS systems that provide strong value not just for startups but also for businesses planning to grow over the coming years.

Merchant Fees Explained
Merchant fees are often the most misunderstood cost associated with POS systems.
Fixed Merchant Rates
Many POS providers use fixed transaction rates.
The advantage is simplicity because businesses always know what they will pay.
The disadvantage is that larger businesses may pay more than necessary.
Negotiated Merchant Rates
Some POS systems provide greater flexibility when choosing payment providers.
Businesses with higher transaction volumes may be able to negotiate better rates.
Why Merchant Fees Matter
A business processing $1 million annually may spend more on merchant fees than software, hardware and support combined.
This is why payment processing deserves careful consideration when comparing POS systems.
Hidden POS Costs Most Business Owners Ignore
Additional Registers
Some providers charge extra fees for every additional register added to the system.
Online Ordering
Online ordering platforms often involve separate subscriptions.
Loyalty Programs
Customer loyalty features frequently require additional fees.
Accounting Integrations
Not every accounting integration is included within the base subscription.
Hardware Replacement
Replacement hardware costs should be considered when comparing providers.
Software Upgrades
Businesses may eventually require more advanced plans as operations become more complex.
When A Cheap POS System Becomes Expensive
As Transaction Volume Increases
Merchant fees become increasingly important as sales grow.
As Staff Numbers Increase
Employee management tools may require paid upgrades.
As Online Sales Expand
Businesses may need online ordering or ecommerce functionality.
As Additional Locations Open
Multi-site management often introduces additional costs.
As Reporting Requirements Grow
Advanced reporting tools are not always included within entry-level plans.
