Plain-English guides to the October 2026 payment reforms — and what they mean for your costs.

From 1 October 2026 you can no longer surcharge eftpos, Mastercard or Visa payments. Here is a plain recap of what ends, what you can still charge, and the numbers behind the change.

Costs are rising everywhere: the one payment line you can actually control
Insolvencies are at record levels and costs are climbing on every front. Most of those pressures are outside your control — but the cost of accepting cards is one line you can actually review.
Flat-rate vs interchange-plus: how the two pricing models compare
Almost every provider prices card acceptance one of two ways — a single flat rate, or interchange-plus. The October 2026 interchange cut changes how they stack up. Here is how each works, in plain English.
eftpos vs credit cards: why the way a customer pays changes your cost
eftpos is usually the cheapest network to process, though on a flat rate you pay the same percentage either way, so the saving only reaches you on interchange-linked pricing or through least-cost routing.
PCI compliance for small business: a plain-English guide
If you accept cards, PCI DSS applies to you. The good news: using a compliant provider does most of the heavy lifting. Here is what it means and what you actually need to do.
Chargebacks explained: what they are and how to reduce them
A chargeback reverses a card payment when a customer disputes it — and it can cost you the sale plus a fee. Here is how the process works and practical steps to reduce them.
How much does card processing cost in Australia?

Tap to Pay on iPhone and Android: taking card payments without a terminal
Tap to Pay turns a phone into a contactless card reader — no separate terminal, no hardware to buy. Here is how it works in Australia, which providers offer it, what it costs, and where it fits.
Least-cost routing (merchant choice routing): how to cut debit card costs
Least-cost routing (also called merchant choice routing) sends contactless debit taps down the cheaper network. After the October 2026 surcharge ban it becomes one of the few levers left to lower what you pay — here is how it works and how to switch it on.
How to read your merchant statement or payments bill
Your October payments bill arrives in early November. For most merchants it will look much like September's. The cost will not. Surcharging ended on 1 October. The fee did not change. Who pays it did. Three numbers off the bill tell you what you now absorb and whether your provider passed the interchange cut on.
