Accountants, lawyers, financial planners, consultants, architects, marketing agencies — most professional services firms get paid by invoice, not at a counter. So when payments come in, they tend to come in big lumps: a $4,800 tax return, a $12,000 conveyancing matter, a $25,000 retainer instalment.
That changes how you should think about eftpos. The same rates that look fine on a $25 cafe transaction can quietly cost you hundreds of dollars on a single invoice. And because most professional firms accept cards almost entirely as a courtesy, the cost-of-acceptance question gets ignored for years at a time. Here's how to think about it properly.
Why "Eftpos" Looks Different for Professional Services
If you're a tax agent or a small law firm, the typical payment mix looks something like this:
- Bank transfer (EFT) — the cheapest and most common
- BPAY — common with corporate clients
- Card payment via your accounting software (Xero, MYOB, Reckon, FreshBooks, etc.) — increasingly the default
- Card payment via a physical eftpos terminal in reception — sometimes
- Direct debit for ongoing engagements — common in advisory and bookkeeping
The card portion is the bit that costs you money. Even if it's only 30% of your revenue, a fee of even a fraction of a percent on big invoices adds up to thousands of dollars a year. Worth getting right.
Card Payments Through Your Accounting Software
Most professional firms today accept cards through whatever payment service their cloud accounting software bundles in. Click "pay now" on the invoice email, customer types in the card, money lands in your account a couple of business days later.
It's convenient. It's also rarely the best deal once your card volume grows. The bundled options inside accounting platforms charge a flat per-transaction percentage — fine on a $200 invoice, painful on a $20,000 one.
What to know:
- Most cloud accounting platforms let you connect a different payment provider — you're not locked into the default. The "Pay Now" button can be wired to a Stripe, eWay, Pin, Westpac PayWay or other gateway with bespoke pricing.
- Once you're consistently doing $20k+ a month in card payments via invoices, a custom gateway with negotiated rates often pays for itself within weeks.
- Some providers offer interchange-plus pricing for online card-not-present payments, which can dramatically reduce your cost on Australian-issued debit cards.
The Surcharging Question (and What's Changing in October 2026)
Many professional services firms surcharge — particularly on credit card payments. That's been a fair way to recover the cost of accepting cards on a $15,000 invoice.
From 1 October 2026, that's set to change. The RBA has confirmed a card surcharge ban for debit and credit cards on the eftpos, Visa and Mastercard networks. Once it kicks in, you can no longer pass card costs back to your client.
What that means for your firm:
- Anything you currently surcharge becomes a cost you have to absorb.
- That makes your card processing rate a real bottom-line item, not a recoverable pass-through.
- If you've been on whatever rate your software defaulted to, now's the moment to negotiate or switch.
Our eftpos surcharging guide covers the rule changes in more detail.
Should You Even Have a Physical Terminal?
Some firms have a terminal at reception — handy for clients who prefer to tap a card after their meeting. Others have abandoned counters entirely and run online-only. Both are valid.
If you're going to have a terminal, the brief is simple: small footprint, integrates cleanly with your accounting software so payments reconcile automatically, and the rate is sensible. You're not running a retail business — you don't need a $1,500 POS bundle.
For most professional firms, a single 4G smart terminal at reception plus a well-priced online gateway is more than enough.
Trust Accounts and Compliance
If you're a law firm, you've got an extra layer to think about. Money paid for legal fees on invoice can usually go straight to the operating account, but funds held on behalf of clients — settlement money, deposits, advance retainers in some structures — need to land in a regulated trust account.
Most modern legal practice software handles this routing if you wire your payment provider to it correctly. Get this wrong and you create a compliance headache, not a cash flow improvement.
Same principle applies to mortgage brokers, real estate agents, financial planners, and conveyancers — anyone holding client funds. Your gateway needs to settle into the right account, every time, automatically. Worth checking before you switch.
Big Invoices = Big Rewards Opportunity
Here's where professional services firms often miss out. If you're processing $200k–$500k+ a year in card payments, you're exactly the volume profile that benefits most from rewards-based payment setups. We're talking serious Qantas Business Rewards points, or cashback rebates on a Mastercard tied back to your business.
If a client pays you $30,000 by card and you're not earning anything on that transaction beyond having the money in your account, you're leaving real value on the table. Our Qantas Points from eftpos guide walks through how the rewards mechanic works.
Direct Debit for Ongoing Clients
If you've got monthly retainer clients — bookkeeping, ongoing legal advice, compliance subscriptions — direct debit is usually the right tool, not card.
It's cheaper than card processing, settlement is predictable, and you don't get hit with chargeback risk. Most professional services accounting platforms have direct debit integrated, but not all are priced the same. Worth asking what your effective per-debit cost is, especially if you're managing 50+ clients on monthly retainers.
Common Mistakes Professional Services Firms Make
- Sticking with the bundled "Pay Now" rate forever. Fine for $5k/month in card payments. Costly when you're at $50k.
- Ignoring rates because clients are paying. Even if your clients foot the surcharge today, that ends in October 2026. Then it's your problem.
- Mixing card and trust funds. Get the routing wrong and you create a compliance issue, not a cost saving.
- Never asking for a rewards setup. If you're invoicing big card payments, this should be a standard question of any provider.
- Treating card processing as someone else's problem. It's a margin item. Treat it like one.
Our Honest Take for Professional Services Owners
The right setup depends on your firm size, your software stack, your client mix, and how much of your revenue actually flows through cards. For most firms doing $250k+ in card payments a year, a quick review of your gateway and rate structure will surface savings — and almost always uncover a rewards opportunity that nobody told you about.
