The headline rate isn't the whole story
When a payment provider quotes you "1.9%" or "1.4% in-person", they're quoting the transaction rate, what they keep from every card payment processed through their system. That rate is real, and it matters. But it's rarely the only cost you pay.
Across Australian businesses, the full cost of accepting card payments is typically 30–70% higher than the quoted transaction rate once all fees are included. For a business on a 1.9% rate, the real effective rate often sits between 2.5% and 3.2% when everything is counted.
This guide breaks down every component, so you know exactly what you're paying, and exactly what changes when the October 2026 surcharge ban takes effect.
The components of card acceptance costs
Card acceptance costs fall into several distinct categories. Most merchants are aware of the first; far fewer track the rest.
What the surcharge ban actually means
For most of the past decade, Australian merchants have had a legal escape valve: if accepting cards costs money, charge the customer for it. The practice is common (particularly in hospitality and professional services), and has allowed merchants to pass through some or all of their card acceptance costs.
From October 2026, that escape valve closes. Surcharging consumers for card payments will be prohibited under proposed amendments to the Payment Systems Regulation Act, following recommendations from the RBA's 2025 review of payment surcharging.
"A business on a 1.8% card rate processing $60,000 per month currently passes $1,080 of costs to customers every month. From October 2026, that $1,080 becomes a monthly business expense."
This is not a theoretical risk. It's a scheduled margin compression, and the lead time to prepare is measured in months, not years. Businesses that act now have time to adapt their pricing, their payment mix, and their customer proposition. Those who don't will face an abrupt cost shock in the October–December 2026 trading period, which for many retailers and hospitality businesses is their most important quarter.
Running the real numbers
Here's what the full cost stack looks like for a typical Australian café or restaurant, before and after the ban.
That's a jump from $130/month to $1,030/month (a $10,800 annual increase), with no change in volume, no change in rates, and no change in anything except the law.
For a café running on 8–12% net margins, that's a meaningful hit. On $600K annual turnover, $10,800 represents 1.8 percentage points of margin. It's not catastrophic, but it requires a response.
The hidden cash flow hit: rolling reserves
Beyond the fees, many merchants (particularly those on bank-linked EFTPOS or traditional acquiring contracts) face a cost that never appears in the rate card: the rolling reserve.
Here's how it works: your acquiring bank withholds a percentage of every transaction you receive (typically 5–15%) and holds those funds for 90 to 180 days as security against chargebacks and disputes. The money is yours in theory. In practice, it sits in their account, not yours, and the pool is continuously replenished as new transactions arrive. The result is a permanent cash flow shortfall that grows with your volume.
Most merchants don't know it's happening until they look closely at their settlement reports. Many just accept it as normal. It isn't.
That's $15,000 of your own money, earned from your own customers, sitting unavailable, indefinitely. If you're using a business overdraft or credit line to bridge cash flow, you're paying interest on money you've already earned but can't access. The reserve doesn't show up as a fee, so it rarely gets accounted for in profitability analysis. But it's real, and it's significant.
UniPay has no rolling reserve. Every UniCash payment hits your UniPay balance immediately. When you request a payout, you receive your full available balance, nothing held, nothing withheld, no minimum reserve. The working capital impact is zero.
What are your options?
Merchants have three realistic levers to work with when the ban hits:
1. Adjust your pricing
The most straightforward response is to build card acceptance costs into your prices. If your café currently adds a 1.5% surcharge on card payments, you raise menu prices by 1–1.5% and absorb the cost into the base price. The customer pays the same; you maintain margin. The challenge: in competitive environments, price increases need careful positioning, and price comparisons are more visible than ever.
2. Negotiate your card rates
Most small businesses accept the standard rates without negotiation. If you're processing more than $30,000/month, you have enough volume to negotiate, particularly with bank-linked EFTPOS providers and some mid-tier providers. A 0.3–0.5 percentage point reduction is achievable in many cases and can significantly reduce the impact of the ban.
3. Change your payment mix
Not every dollar needs to run over a card network. Businesses that can encourage (or incentivise) customers to use payment methods with lower acceptance costs will naturally reduce their exposure. This is where alternative payment systems like UniPay become relevant: UniPay's service rate starts at 1.2% and drops to as low as 0.6% as your volume grows, with no interchange or chargeback costs, and payouts to your bank are free. If some of your transaction volume moves to UniPay, the blended effective rate across all transactions falls significantly.

UniPay is a merchant acceptance network built on the UniCash platform. When a customer pays with UniCash, a simple service rate is applied to the payment, rates start at 1.2% and drop to as low as 0.6% as your volume grows. No interchange, no card network fees, no chargebacks. Your balance always reflects the net amount.
When a merchant wants to move funds to their bank account, the payout is free, and you receive exactly your available balance. There are no chargebacks, no rolling reserve, no lock-in contract, and no surprise deductions at payout.
For businesses in communities with high UniCash adoption (particularly in areas with significant migrant populations, where UniCash has meaningful traction), UniPay payments may already be a natural part of the customer mix. For others, the October 2026 ban creates an opening to introduce UniPay as a complementary payment option before costs escalate.
