Why Card Terminal Fixed Fees Quietly Drain Your Business – I'll Tell You Honestly

If you're a franchisee who receives settlement statements every month, you've probably had this experience: "Wait, what's this charge?" "It went up again compared to last month?" Card terminals work like a silent leaky faucet, quietly absorbing funds bit by bit each month. The fee rate alone looks like 2-3%, but when you add rental fees, communication costs, and maintenance charges, the actual burden is much larger. Particularly for small franchisees, these fixed costs become the critical variable determining net profit.

This article is written based on the inconveniences experienced by franchisees that Shim Jae-woo, CEO of TheKL Link (specializing in PG payment processing and platform construction), has witnessed firsthand in the field. The overall cost structure principles of card terminals were organized in Series 1 Comprehensive Guide, and this article focuses on honestly addressing the costs you've missed, why you regret contracting, and whether these are actually unavoidable.

"We only charge 2.5% commission!" "Lowest fee guaranteed!" There are plenty of advertising claims. But when you look at the settlement statement, something feels off. The fee is definitely 2.5%, yet the total cost is more.

This is a structural limitation of the card terminal industry. There are already multiple items classified as fees, and hidden costs are embedded throughout the settlement structure that don't fall under the fee category. Beyond simple transaction fees, card company surcharges (which vary by card company and category), communication charges, rental fees, maintenance costs, and annual fees are all billed at different times and under different names. Some are even written in small print in the contract, or suddenly added later without prior notice.

"You cannot understand actual costs by looking at fees alone" — this is the most uncomfortable truth about this industry.

* Card company surcharges beyond the displayed fee average an additional 0.3-0.8%
* Cost structure for recovery requests to technical support during communication failures is ambiguous
* Options presented as "choices" (e.g., premium security, data backup) are effectively mandatory

When franchisees asked during contract signing "Is this really necessary?", most PG salespeople responded, "It's included in the basic package..." This is true but also a trap. Because the cost of that "inclusion" and whether it can be removed separately is never explained.

Small franchisees in particular don't have much leeway to absorb this structure. If monthly transaction volume is 5 million won, the fee could be 125,000 won, but fixed rental and communication costs alone eat up 30,000-50,000 won each month. While large franchises are compensated by fee reductions thanks to larger transaction volumes, self-employed and small business owners face a proportionally much heavier fixed cost burden.

Another trap is "early contract termination." Even if you're unhappy with the terminal or want to switch to a PG with better terms, if the contract period (typically 36-60 months) remains, you must pay early termination fees. These penalties are often unclear, so when you receive the settlement statement, you discover them with "Wait, what's this?"

* Rental alone ranges from 15,000-40,000 won per month, but if handled as "basic inclusion," there's unlimited room for increases
* Communication fees (LTE, WiFi, fixed internet) are billed in complex ways, making it difficult to judge whether there's duplication
* If the contract includes "future cost adjustment" clauses, verbal promises have no effect

"Same-day settlement! Check your sales immediately!" Franchisees who see these ads have high expectations. Faster cash flow makes business operations much easier. But when you actually receive the settlement statement... "You said same-day settlement, but why is it next day?" "Yesterday it came in at 3 PM, so why 8 PM today?"

The problem runs deeper. "Fast settlement" is often bundled with additional costs. Standard settlement (T+3, meaning after 3 business days) has a base fee of 2.5%, but to get same-day settlement, you need to pay a 0.2-0.5% premium. On 10 million won in monthly transaction volume, that premium alone is 20,000-50,000 won per month.

Additionally, the concept of "settlement" itself is ambiguous. Deposited amount ≠ actual sales. Card company surcharges, fees, fraud prevention reserves (amounts withheld to prevent fraud), refunds, and cancellations are already deducted from the deposited amount. Mismatches occur in this process: "I had 1 million won in transactions yesterday but only 960,000 won was deposited?" If the reason for this discrepancy isn't clearly stated in the settlement statement, the franchisee remains perpetually suspicious.

* "Same-day settlement" is technically possible but has many limiting conditions (e.g., daily limits, card company exclusions)
* Settlement fee premiums and card company surcharges may be double-billed
* Settlement holds (Chargeback Reserve) are clearly your money, but recovery conditions are ambiguous

"I heard online payment is cheaper these days?" "No, offline card terminals are said to be more affordable?" Franchisees are caught in this dilemma and keep postponing their choice.

The reality is both are expensive but have different cost structures. Offline card terminals have fixed rental and fixed costs, but if monthly transaction volume is low, the fixed cost proportion increases. Online payment (PG) has minimal or no fixed costs but often has higher fee rates. For example:

Scenario 1: Small coffee shop with 3 million won monthly transaction volume

•Offline card terminal: 2.8% fee (84,000 won) + rental 25,000 won + communication 8,000 won = approximately 117,000 won

•Online PG: 2.9% fee (87,000 won) + fixed cost 0 won = approximately 87,000 won

→ Online is 30,000 won cheaper

Scenario 2: Franchise with 50 million won monthly transaction volume

•Offline card terminal: 2.3% fee (1,150,000 won) + rental 25,000 won + communication 8,000 won = approximately 1,183,000 won

•Online PG: 2.9% fee (1,450,000 won) + fixed cost 0 won = approximately 1,450,000 won

→ Offline is 267,000 won cheaper

But even this calculation doesn't hold at the start of the contract. Many franchisees receive "new customer discounts" early on, then see normal fees kick in after 6 months. Card company policy changes during the contract period can change surcharges too. Because of this variability, regrets emerge: "I contracted based on calculations from 3 years ago but now somewhere else is much cheaper."

* Online PG has no fixed costs and simple termination procedures, but fee increases can be sudden
* Offline card terminals are stable but early termination penalty is an issue
* Attempting to "run both in parallel" actually increases costs, creating a paradox

Franchisees receiving a "cost increase" notice usually respond with protest: "This wasn't shown in the contract?" "Why was it raised without notice?" But in most cases, somewhere in the contract there's a clause like "May be adjusted based on price indices," or the PG company responds "Card company policy changed."

Worse cases involve PG companies claiming the increase isn't really an increase. For example, they explain by separating items: "The fee is the same, only communication charges went up" — then the franchisee accepts it thinking "Well, that's unavoidable." But in reality, the total amount paid each month has increased.

Additionally, card association assessment increases are often deferred by claiming they're outside PG company control, suggesting franchisees must negotiate directly with card companies. But realistically, individual franchisees cannot negotiate directly with card companies. This is the value of the PG company distributor network, but there's an irony that this value doesn't properly function in cost negotiations.

* When contract terms explicitly grant cost adjustment rights, policy changes become valid through PG company notification alone
* Card company surcharge increases are positioned as "market fluctuations" and kept outside responsibility
* The structure is designed so that by 12-24 months when franchisees consider switching PGs, the penalty reaches its maximum

Cash flow management is the lifeblood of small business owners. For a café processing 1 million won daily in transactions, when 30 million won is deposited monthly determines business stability. Therefore, many franchisees prefer PG companies promising "same-day settlement."

But reality is different. Even if settlement cycles are faster, the gap between actual sales and deposited amounts tends to widen. This is because same-day settlement leaves no time for fraud verification. So PG companies withhold "fraud prevention reserves," and if the conditions and timeline for releasing these reserves aren't clear, your capital ends up locked in a non-moving state for weeks.

Additionally, the fee difference between "T+1 settlement" (next business day settlement) and "same-day settlement" is larger than expected. On just 1 million won monthly transaction volume difference, you pay 1,000-3,000 won more — that's 12,000-36,000 won annually. For small franchisees, this is a non-negligible amount. And even if settlement is faster and deposits come in "a week earlier," for businesses with irregular sales (seasonal, event-based) faster settlement might actually worsen cash liquidity.

* Settlement cycle shortening = reduced fraud verification time = increased reserves paradox
* "Same-day settlement" premium accumulates significantly over long-term contracts
* While faster cash flow is ideal, predictability matters more in many cases

Q1: Can I just not use a card terminal at all?

A: Realistically, that's impossible. Card payments have become almost as essential as cash, and merchants cannot refuse them. You could consolidate with online PG, but you'd have to abandon offline consumers (in-store customers). Your choices are really just "which PG company to choose and what terms to contract under."

Q2: I heard there are PG companies with "zero fixed fees" — is that real?

A: Formally, yes. But typically they compensate by charging 0.2-0.5% higher fees, imposing transaction volume limits, or requiring longer settlement cycles. Some charge initial costs under names like "registration fee" or "annual fee." You can only know if it's truly a better option by comparing total costs over an extended period.

Q3: I'm told post-contract fee increases are inevitable — is there any way to fight back?

A: It's important to thoroughly negotiate contract details. Specifically clarify (1) the notice period for fee increases, (2) the maximum increase cap, and (3) whether you have termination rights when fees increase. Additionally, develop the habit of carefully reviewing settlement statements annually to check for unexpected charges, and immediately inquire if something seems wrong. Working through PG distributor networks with strong industry position (e.g., TheKL Link) offers the advantage of having the company advocate for you in card company negotiations.

The card terminal fixed cost problem isn't something to "solve" but to honestly acknowledge reality. Every PG company, every card terminal drains your funds in some way. It's their business model, and there are legitimate reasons (card company fees, fraud prevention, technology maintenance, etc.).

But that doesn't mean you must passively accept all costs. Learning to read settlement statements, calculating total costs clearly before signing, and regularly reviewing other options are your rights. Choosing a good PG partner is also important, but don't just believe "low fees" advertising — choose based on transparent cost structure and customer trust.

Essential Checklist: Must-Verify Before Card Terminal Contract

Have you calculated 3-year total costs directly? (fees + rental + communication + management)

Did you find "cost increase" clauses in the contract? (Are there increase limits?)

Do you clearly understand fee differences by settlement cycle? (same-day vs T+3)

How much do card company surcharges affect total fees? (varies by category)

Have you confirmed termination penalty amounts and conditions?

When does "new member discount" revert to normal pricing?

Are fraud prevention reserve release conditions clearly defined?
