Hidden fees to watch out for in Merchant Services
Hidden fees to watch out for in Merchant Services

It is easy to be led by the flashiest or cheapest terminal offers when choosing a payment provider. However, as the saying goes, there’s often no such thing as a free lunch. Low cost entry points like €1 terminal rentals or eye catching introductory rates are enticing. These deals only tell half the story. The true measure of a payment partner is not the hardware cost or the first month’s bill. It is the total cost of processing over the lifetime of your contract.
At Paymentplus, we believe in looking past the “teaser” prices to uncover the true Total Cost of Ownership (TCO). We are increasingly seeing merchants lured by “bargain” deals only to find their costs skyrocketing six to twelve months later once the “honeymoon period” ends. To protect your bottom line, you need to know exactly where these costs are hiding.
1. The “Non-Qualifying” Trap
This is perhaps the most common way low upfront costs are recouped. Many providers offer a highly competitive “headline” rate for standard personal debit cards. However, the fine print often contains a complex web of “reclassifications”.
If a customer pays with a corporate card, an international card, or even a premium rewards card, the transaction is flagged as non-qualifying. This allows the provider to add a surcharge—often 0.50% or more—on top of your agreed rate. We have audited statements where over 30% of a merchant’s volume was hit with these “additional rates”, effectively subsidising the competitor’s cheap hardware through a hidden tax on every sale.
2. The “Support Subscription” Sting
Reliable support shouldn’t be a luxury, yet many providers have turned “help” into a tiered revenue stream. In these models, basic technical assistance is relegated to slow email queues or automated chatbots. If your terminal goes down during a busy Saturday service and you need to speak to a human immediately, you may discover you are on a “Basic” tier that doesn’t include phone access.
At Paymentplus, we do things differently. We don’t believe in charging you extra for the peace of mind that your business can stay open.
• Local Support Team: We’re a local business based in Dublin, Ireland. We understand the local market and the specific needs of Irish business owners unlike international tech corporations.
• 7-Day Free Phone Support: You can pick up the phone and talk to one of our friendly payment specialists any day of the week without an “add-on” fee.
• No Ticketing Systems: We don’t treat your business like a number in a digital queue. You get direct access to help when you need it.
• Next Day Terminal Swap Outs: If your hardware develops a fault we ensure a replacement is with you the very next working day to keep your business trading.
• Dedicated Account Manager: You have a single point of contact who knows your business, rather than a rotating cast of call centre agents.
3. The “Post Honeymoon” Price Hike
It is a common industry tactic to offer a “teaser rate” to secure a signature. Often providers will only guarantee these rates for six months. Once this window closes, many contracts allow for “annual adjustments”, “inflationary increases”, or “service fee updates”.
Without a transparent, long-term agreement, your rates can climb significantly without a clear explanation. Merchants often don’t notice the incremental 0.10% or 0.20% increases month-over-month until their effective processing cost has doubled from their original “teaser rates” or starting point.
Case Study: How Paymentplus Uncovered a 46% Saving
To understand the real-world impact of these fees, consider this recent statement analysis we performed for a merchant with a monthly turnover of just over €16,000. They believed they were on a “low-cost” plan with a €1 monthly terminal rental, but the reality was eye-opening.
The Result:
By moving away from a plan filled with “non-qualifying” reclassifications, penalty fees, and support surcharges, this merchant saved over 46% on their overall processing costs by switching to Paymentplus.
While the terminal rental was cheap at €1, the statement revealed the following costs:
• Card Transaction Rates: €137.42
• “Additional Rates”: €50.00 (Created by 31 transactions flagged as non-qualifying)
• Secure Transaction Fees: Additional ancillary costs applied throughout the month
The biggest sting on the merchant’s bill was the €50.00 in additional rates. The provider added an extra 0.50% surcharge simply by reclassifying 31 transactions. This loading alone had a massive impact on the bill and is exactly how a €1 terminal is subsidised.
By analysing the full statement and moving the focus away from the hardware cost to the effective blended rate Paymentplus was able to deliver a 46% saving on their overall rates.
Even for merchants on seemingly unbeatable rates, the “all-in” cost often tells a different story. Consider another merchant on an ‘excellent’ 0.12% debit rate. Once we removed the padded service fees and hidden loads, we were still able to deliver a 12% total saving by simplifying their fee structure and providing a fair, honest rate from day one.

Frequently Asked Questions
The most effective way to save on merchant service fees is through a full statement audit. By calculating your total monthly cost rather than focusing on terminal rental, you can identify hidden surcharges. At Paymentplus, our audits frequently uncover savings of up to 46% for businesses by eliminating non-qualifying transaction loads and ancillary fees.
Common hidden fees include non-qualifying surcharges, PCI non-compliance penalties, and secure transaction fees. Many providers also hide costs within “premium” support tiers or increase rates significantly after an initial six month introductory period.
A non-qualifying surcharge is an extra fee, often around 0.50%, added to transactions that do not meet a provider’s “standard” criteria. This typically applies to corporate, international, or premium rewards cards. Providers often use these reclassifications to subsidise low cost hardware offers like €1 terminals.
You should look for transparency regarding long-term rates, 7 day phone support without extra charges, and managed PCI compliance. Ensure there are no hidden ticketing systems for support and ask for a guaranteed “effective blended rate” to understand the true cost of the service beyond the headline offer.
High merchant statements are often the result of “ancillary fees” and “additional rates” added to your base percentage. Micro-fees for secure processing and gateway access can quickly inflate your bill. A professional audit can help you see if you are paying for these hidden extras or if your “teaser rate” has expired.
? Many large providers charge for “premium” support tiers. However, Paymentplus offers free 7 day phone support as standard. We believe Irish business owners should have direct access to human experts without needing to pay for a subscription or wait in a digital ticketing queue.
