Why Starting to Reduce Payment Costs Now Isn't Too Late
Few business owners know exactly how much they're paying in card payment processing fees. Many brush off their monthly expenses with "it's probably about this much," or simply rely on the numbers in their contracts. However, when you examine actual billing statements closely, unexpected costs hide in the details. Shim Jae-woo, CEO of TheKL Link, has witnessed this problem through hundreds of merchant consultations. "Payment costs directly impact business profit margins, yet most people don't pay attention to them. Many cases show that accurate diagnosis alone leads to savings of millions of won annually," he emphasizes. This article traces a real case of an online shopping mall operator who questioned whether payment fees were "fairly priced," discovered overbilling through a free diagnosis, and successfully reduced costs.
The basic principles—including each component of payment terminal costs, differentiation by industry type, and how settlement cycles affect cash flow—were organized in Part 1's comprehensive guide. This article presents the complete Before·Process·After story of one business operator, specifically showing how much costs can actually be reduced and where to start.

"The Same Amount Goes Out Every Month—Am I Paying Too Much?"
Operator A has been running an online shopping mall for three years. They maintain stable monthly sales of approximately 1,000 transactions with an average payment amount of around 120,000 won per transaction. However, monthly payment processing fees amount to approximately 1.8 million won—about 1.5% of total sales. Initially, they thought "this must be standard processing fees." Other shopping mall operators mentioned similar cost levels. However, when early this year brought PG provider contract renewal season, doubts began to emerge. They wanted to verify whether their current contract terms were truly optimal. In particular, concerns kept surfacing: "There might be a cheaper PG provider out there" and "There could be hidden costs like consolidated fees." Little did they know all those concerns had solid grounds.
Operator A's Before Situation:

Applying for Free Diagnosis—Initial Skepticism
Through web search, Operator A discovered TheKL Link's "Card Terminal Cost Free Diagnosis" service. The free diagnosis itself seemed suspicious. "Is this service really free? Will they pressure me into a contract later?" was the first thought. However, the desire to "accurately understand the current payment structure" and the judgment that "it's better to know now if we're losing money" were stronger. Operator A filled out an online consultation request form with business information, current monthly transaction volume, and primary payment methods.
Shim Jae-woo, CEO of TheKL Link located in Jung-gu, Seoul, called the next day. The consultation, which began with the question "Can you prepare your current PG provider's contract?", lasted approximately 30 minutes. CEO Shim meticulously recorded Operator A's transaction volume, industry type (fashion accessories online shopping), and payment method ratios. He then explained: "We need to check whether there are items like monthly management fees, service fees, and settlement delay charges beyond the base rate." Operator A's suspicions were already preparing to become reality.

"After Re-reading the Contract, All These Things Were There"
The core of the diagnosis was "clarifying the current billing structure." Operator A received a "payment cost checklist" from TheKL Link. It outlined what needed to be confirmed beyond the base fee:
When Operator A re-read their PG provider's contract—used for the past three years—they discovered multiple "overlooked" items, though not truly "hidden" costs. In particular, an "additional charge for T+3 settlement cycle option" amounted to approximately 150,000 won monthly, and "communication fee" of 50,000 won was being billed separately. CEO Shim explained: "These items can be individually negotiated. Shortening the settlement cycle to T+2 can eliminate that additional charge, and separate communications contracts with other providers might be cheaper. Additionally, your current base fee rate is set 0.1–0.2% higher than industry standards."
Overbilling Items Operator A Discovered:

Renegotiation—Happened Faster Than Expected
CEO Shim Jae-woo of TheKL Link prepared an "improvement proposal" comparing Operator A's current terms with market standards. The proposal included:
Operator A brought this proposal to their current PG provider and requested "condition improvements." Remarkably, the current PG provider also agreed to negotiate for "customer retention." They quickly agreed to the 0.2% fee reduction and settlement cycle improvement. It wasn't necessary to switch to a completely new PG provider. Because TheKL Link's proposal provided "evidence of market standards," the existing PG provider adjusted terms to maintain competitiveness.
Key Aspects of Negotiation Process:

Three Months After Diagnosis—Here's What Actually Changed
Three months have passed since Operator A applied the improved terms. The changes were clear:
After Situation:
Most importantly, these costs will continue to be reduced going forward. This wasn't a one-time savings but a restructured system generating 450,000 won more profit monthly. Operator A reflected: "If I'd maintained the status quo for three years, I'd have lost over 15 million won." They added: "To avoid missing such opportunities, you must review the cost structure at least once during contract renewal season or annually."
CEO Shim Jae-woo of TheKL Link explains: "Payment costs are a blind spot. Many business owners accept them as if 'this level is normal,' but in reality, there's always room for negotiation and improvement." He emphasized: "Simply securing objective figures through free diagnosis becomes negotiation leverage, leading to savings in the 5 million won range annually."

Could My Business Be in a Similar Situation?
Q1: Is the card terminal fee free diagnosis truly free?
A: TheKL Link's free diagnosis is completely free for initial consultation and current situation analysis. While diagnosis results present improvement methods, actual contract changes are driven by the business operator. TheKL Link provides "objective standards" during the negotiation process, and subsequent service use is entirely the operator's choice. In Operator A's case, improvements came through renegotiation with the existing PG provider, though some cases involve switching to new providers. The important point is that "the operator retains choice."
Q2: Do I have to switch PG providers to reduce payment costs?
A: Not necessarily. As in Operator A's case, significant savings are possible through renegotiation with the current PG provider alone. The key is "accurately understanding the cost structure and knowing market standards." With objective figures obtained through TheKL Link's free diagnosis, you can make persuasive requests at the negotiation table with your existing PG provider. However, if they show "no improvement intention," it's worth considering switching to a new PG provider.
Q3: When is the best time to start reducing payment costs?
A: Contract renewal season (typically early or mid-year) is ideal. However, there's no need to wait for a "good time." Right now is a good time to start. Why? Because every day that expenses are improved, that much profit accumulates. Like Operator A, simply "checking just in case" can reveal annual savings opportunities worth millions of won.

Conclusion: Accurate Diagnosis Is the First Step to Cost Reduction
Card terminal fees appear to be "fixed costs," but they actually offer significant room for negotiation and improvement. As seen in Operator A's case, hidden within three years of "naturally assumed" costs was a monthly 450,000 won unnecessary expense. Without TheKL Link's free diagnosis provided by CEO Shim, Operator A would have continued paying that cost indefinitely.
Confirming whether your business is paying payment costs "appropriately" isn't difficult. After submitting an online consultation request and sharing your current contract and monthly transaction volume, the free diagnosis proceeds. Based on the diagnosis results, you can either renegotiate with your existing PG provider or switch to a new one—the choice is entirely yours. What matters is "having information to make that choice."
If you feel payment processing fee reduction is necessary, apply for TheKL Link's free payment environment diagnosis right now. A simple consultation alone can clarify your current situation, which may lead to savings worth millions of won. TheKL Link has operated as a payment cost reduction specialist in Jung-gu, Seoul for over five years, providing practical improvement methods through thousands of merchant consultations.
