What a payment processor actually does
In Ireland, the words processor, acquirer, PSP and terminal provider get used interchangeably, usually by the people selling them to you. They're not the same thing, and the difference matters once you start comparing offers.
- The acquirer is the licensed financial institution that settles card funds into your bank account. There are a handful of these serving the Irish market.
- The PSP (payment service provider) packages an acquirer's capability into a product, a terminal, a hosted checkout, a virtual terminal.
- The broker sits above all of them and brokers the best fit for how your business actually trades.
Most Irish SMEs end up with whichever provider's rep walked through the door, or whoever their bank cross-sold. That's not a strategy, it's a default. The point of this guide is to swap the default for something you actually chose.
The four costs every Irish merchant should check
Every card processing bill stacks four costs on top of each other:
- Interchange. Set by Visa and Mastercard, regulated under EU caps for consumer cards. You can't negotiate this, but if your provider only quotes you a single "blended" rate, you can't see it either.
- Scheme fees. Visa and Mastercard's own per-transaction and assessment fees. Small, but they add up across thousands of transactions.
- Acquirer markup. This is the only part actually up for negotiation, and the only part most merchants never see broken out.
- Terminal rental and ancillary fees. PCI compliance fees, monthly service charges, MOTO surcharges, chargeback fees. The fine-print stack.
A statement that buries all four into a single percentage is a statement designed to stop you comparing. Ask for IC++ pricing (interchange plus scheme plus markup, quoted separately) or at the very least a clean breakdown of the markup.
Five questions to ask any provider before you sign
- What's your acquirer markup, quoted separately from interchange and scheme fees?
- What's the contract term, and what's the early-exit fee on the terminal as well as the processing?
- How fast is settlement, same-day, T+1, T+2, and is there a fee to bring it forward?
- What's your support model when a terminal goes down on a Saturday lunchtime?
- If my volumes change, when do my rates get reviewed, automatically, or only when I ask?
Which kind of provider suits your business?
Four broad categories serve the Irish market. None is universally better, the right one depends on your size, your sector and how much complexity you're willing to manage.
Bank-owned acquirers
Familiar, comfortable, often bundled with your business account. Pricing is rarely the sharpest, but the integration is one less thing to think about. Best for businesses that prize a single point of contact over keenest rate.
Independent acquirers
Specialist focus, often willing to sharpen pricing for the right volume profile. Service quality varies widely, the rate on the proposal is only as good as the team behind it.
PSPs and aggregators
Fast onboarding, flat per-transaction pricing, strong online and omnichannel toolkits. Convenient at low volume; expensive once your card turnover grows past a certain point.
Brokers
Sit above the market. Benchmark you across multiple acquirers, broker the right fit, and stay on as your single point of contact when something breaks. Best for businesses that want choice without managing the comparison themselves.

FAQs
How much does card processing cost in Ireland?
There's no single number, total cost is a stack: interchange (set by the card schemes), scheme fees, the acquirer's markup, and any terminal rental. For a typical Irish SME doing under €500k a year on cards, an all-in rate of 1.0–1.6% on consumer credit, lower on debit, is a reasonable benchmark. Above that, you're almost certainly overpaying.
Is there a difference between an acquirer, a PSP and a broker?
Yes. An acquirer is the licensed institution that settles funds into your bank account. A PSP (payment service provider) sits on top of an acquirer and usually offers a packaged product with a terminal or online checkout. A broker, like Rook, sits above both and negotiates across the market on your behalf, so you're not locked to whichever provider rang you first.
Can I switch payment processors without disrupting my business?
Yes, if it's planned. A clean switch keeps your existing terminal running until the new one is live, ports your settlement details, and aligns to a quiet hour for the cutover. The risk is doing it ad-hoc on a Friday afternoon. A broker handles the choreography.
Do I need a long-term contract?
No. Anything beyond 12 months should be a deliberate choice you make for a price concession, not the default. Watch for auto-renewal clauses and early-exit fees buried in terminal rental agreements rather than the headline processing contract.
What is the average card transaction fee in Ireland?
Debit card transactions are typically the cheapest, sitting in the low double-digit cents on small tickets, while consumer credit and commercial cards can land around 1.5–2.5%+ depending on the acquirer and your volume. The averages hide huge variance, the only number that matters is yours, on your statement, after every line item.
