How to negotiate better merchant fees with your bank before the surcharge ban

The RBA has said plainly that small businesses should be the biggest beneficiaries of October's interchange reductions [1]. Whether that happens at your business depends on a conversation most merchants never have. Here's how to have it — with the leverage, the script, and the traps.

Why right now is the moment

Three forces converge before 1 October, and all of them are on your side of the table:

1. Your provider's wholesale costs are about to fall [1] — so "we can't go lower" is weaker than it's ever been.
2. ~20,000 surcharge-model merchants are entering the market at once [3] — every acquirer has switching offers live, which resets what "competitive" means.
3. Retention beats acquisition. Keeping you is cheaper than replacing you, and your bank knows it. Retention teams hold pricing latitude that front-line scripts don't.

That leverage decays after October, once the switching wave settles. Use it while it's real.

Do this before you dial

Negotiating without numbers is asking. Ninety minutes of prep converts it:

• Know your effective rate (total fees ÷ card turnover — see our statement guide).
• Run an independent comparison at your volume and screenshot the top two or three totals. Named rivals with dollar figures — a bank simple-rate at ~1.0% ex-GST plus rental, a fintech flat with zero fixed fees, ANZ Worldline's blended 0.95% inc-GST — beat "I hear other banks are cheaper" every time [3].
• Know your exit terms (notice period, equipment return). Saying "I'm on 30 days' notice" lands very differently from not knowing.

The script

Call business banking, ask for merchant services — retention or pricing review (not general support), then:

"I've reviewed my merchant statement ahead of the October RBA changes. My effective rate is [X]% on about $[Y] a month in card sales. I've run an independent comparison and I can get an equivalent card processing costs of $[Z] elsewhere. Two questions. First: how will the October interchange reductions be applied to my account, specifically? Second: what can you do on my pricing today to keep my business?"

Why it works: the first question is a fork they can't dodge — an interchange-linked plan has a concrete answer; a flat-rate plan's honest answer is "your rate doesn't change", which hands you the follow-up ("then the saving is going to your margin — so meet the market on my rate"). The second question moves the call from information to offer.

Reading the counter-offer

• Rate cut with no strings — the clean win. Get it in writing with an effective date.
• Rate cut + new lock-in — caution. The reforms are designed to keep pushing acceptance costs down over time [1]; a 24-month lock-in in a falling market has a real cost. Counter: same rate, no term.
• Waived rental / bonus months — fine as sweetener, but fixed-fee candy fades; the rate is what compounds.
• "That's already our best pricing" — now your comparison screenshot does the talking. If they won't move and the market beats them on card processing costs, the negotiation has answered your switching question for you.

Whatever lands: written confirmation, effective date, and check the next two statements — negotiated cuts have a documented habit of missing the billing system.

What this means for you

A fifteen-minute call, armed with two numbers and one screenshot, is the highest-hourly-rate work available to a small business owner this quarter. Best case you save thousands without changing anything; worst case you learn your provider won't compete — which is worth knowing before October, while every alternative is courting you.
