Is your card machine costing you more than it should?
👑 Key points at a glance
Most business owners I speak to do not know exactly what their card machine is costing them. They know the rough percentage, sometimes. But the full picture, including monthly charges, the PCI fee, what the authorisation fee actually is, and when the contract renews, tends to be a blur.
That is not a criticism. You are running a business, not a payments operation. But the blur is expensive if it means you are on the wrong setup for how you trade, or locked into something that made sense two years ago and does not now.
Here is what to actually look at.
Can you read your statement?
If your monthly statement is genuinely confusing, that is the first sign something needs checking. A statement should be readable by a normal person with no payments background. If it is not, either the provider has structured their billing to obscure things, or nobody has ever walked you through what each line means.
A typical statement shows your total card turnover for the month, the transaction fees applied to it, and any fixed monthly charges alongside. If yours shows a list of codes with no explanation, or bundles everything into a single net figure with no breakdown, ask your provider for a fully itemised version. They are obliged to provide one.
The charges worth identifying on any statement are the transaction rate, any monthly service or rental fee, the PCI DSS compliance fee, authorisation fees, and any minimum monthly service charge that applied. My guide to how card machine fees work covers what each of those means in detail.
If your statement has charges you cannot account for, that is a conversation to have with your provider. Most will explain them. If they cannot or will not, that tells you something.
Do you know when your contract renews?
This is the one that catches more businesses out than the transaction rate ever does.
Most card machine contracts include an auto-renewal clause. When the initial term ends, the contract rolls over for another full period, often 12 months, unless you have given written notice to cancel within a specific window before the end date. That window is usually 30 to 90 days, and it is almost always buried several pages into the original agreement.
I have spoken to business owners who did not realise their contract had renewed until they tried to leave and were told they owed months of exit fees. The contract was not unreasonable in its terms. They just had not checked.
If you do not know when your current contract ends, find the original agreement and look for the initial term length and the cancellation notice period. Put a reminder in your calendar two months before that date. That is enough time to review your options without any pressure.
Are there charges on your statement you were not told about?
The transaction rate gets most of the attention. The charges that quietly add up are usually the fixed ones.
PCI DSS fee.
This covers compliance with the Payment Card Industry Data Security Standard, a set of security requirements for any business accepting card payments. Some providers charge a monthly fee for maintaining your compliance status. What I see regularly when I look at client statements is a PCI fee being charged when the business is already compliant and the provider is not actively doing anything to maintain that compliance. If you are paying a PCI fee, ask your provider exactly what it covers.
Monthly minimum service charge.
Some contracts include a floor: if your transaction fees in a given month do not reach a specified amount, you are charged the difference. This is a genuine trap for seasonal businesses, anyone who has a quiet month, or a new business that has not yet built card volume. Check whether your contract has one.
Authorisation fees.
A small per-transaction fixed charge on top of the percentage. Fine in isolation, but if your business takes a high volume of lower-value transactions, these stack up. A busy sandwich shop processing a hundred contactless taps a day is paying that authorisation fee a hundred times a day, and that cost is invisible if you only look at the percentage rate.
None of these charges are inherently wrong. What matters is whether you knew about them, and whether they match what you were quoted when you signed up.
Does your card machine actually fit how you work?
A machine that is wrong for how you trade costs you in ways that do not show up on the statement.
A portable terminal that drops connection in your venue, a countertop machine on a market stall, a device that cannot handle table payments in a restaurant: each creates friction every time a customer wants to pay. Some of that friction ends in a declined payment or a customer walking away. Some of it just slows the queue.
The questions to ask are: does the machine work reliably in the environment where you use it, does it connect to whatever else you use (till system, booking software, accounting package), and does it handle the payment types your customers actually use?
For businesses that move around, connectivity matters. A machine running on 4G with its own SIM does not depend on the venue’s WiFi. For businesses with a fixed location and high volume, a countertop terminal integrated with the till is usually the better fit. Getting this right is not about features for their own sake. It is about whether the payment process works smoothly every time without thinking about it.
Has anything changed in your business since you set this up?
The setup that was right when you started may not be right now.
If your turnover has grown significantly, you may be processing enough volume to qualify for a different contract or a better rate. If you have expanded from one location to two, or started taking online payments alongside in-person ones, your original machine and contract may not cover what you actually need. If the person who understood the system has left and nobody replaced that knowledge, small problems can quietly become habits.
None of this requires an urgent overhaul. But it is worth checking periodically, and the contract renewal window is the natural moment to do it. If anything in this post has flagged something you want a straight answer on, that is exactly what a statement check is for.
Frequently asked questions
How do I know what pricing model I am on?
Look at your statement. If every transaction shows the same rate regardless of card type, you are almost certainly on blended pricing. If you see different rates for different transactions with separate lines for interchange and a provider markup, you are on IC++. If you are still not sure, ask your provider directly. They are obliged to tell you.
Can my provider change my rate without telling me?
It depends on your contract. Many contracts allow rate changes with a period of notice, which can be as short as 30 days. Check the variation clause in your original agreement. If you have not seen a copy recently, ask your provider to send one.
What is a reasonable notice period to cancel a card machine contract?
30 to 90 days is typical. Anything longer than 90 days is unusual and worth questioning. Some rolling monthly agreements require as little as 30 days. Always check the specific clause in your contract rather than relying on what you were told verbally when you signed up.
Should I worry about my card acceptance rate?
If a notable proportion of your card transactions are being declined at the terminal, that is worth investigating. Occasional declines are normal, but a pattern suggests either a configuration issue with the machine or a problem with a specific card type. Your provider’s support team should be able to pull decline data for your terminal.
Is it worth switching providers just to get a lower rate?
Not automatically. A lower rate on a longer contract with worse support and a hardware fee can cost more overall than a slightly higher rate with a flexible agreement. The calculation depends on your actual monthly volume, your card mix, and how important things like next-day settlement and reliable support are for how you trade. A like-for-like comparison across the full cost is the only way to know.
What if I am still within my contract term?
You have options, but early exit usually costs money. Check your contract for the termination fee clause, which is typically the remaining months of fees as a lump sum. In some cases the savings from switching justify paying to leave early. In others it is better to wait for the renewal window. That calculation is straightforward once you know the actual numbers on both sides.
