Payment Cost Challenges for Fintechs and PSPs and How to Solve Them

Did you know that fintechs and PSPs lose up to 1.5% of annual revenue to hidden payment discrepancies and inefficiencies, according to Forrester? Why are payment costs still bleeding margins dry in 2025 that too despite tech advances? With transaction fees skyrocketing across PSPs, banks, and networks, plus compliance headaches under PSD3 and PCI DSS 4.0, finance teams face a brutal squeeze. The winners? Those wielding AI-powered automation to slash leakage, reclaim profits, and turn payments into a growth engine. Want to explore more? Let's deep dive.

Core Payment Cost Challenges for Fintechs and PSPs

Traditional PSP business models primarily focused on just moving money are increasingly under pressure. Merchants demand more value-added services such as embedded finance, analytics, and enhanced customer experiences, further squeezing gross margins.​ The typical PSP fee ranges from 2.5% to 3.5% per transaction plus fixed fees, while banks often impose up to 6.2% on cross-border transactions due to foreign exchange and settlement complexity. Card network interchange fees add another 1.5% to 2.5% cost, varying by card type and geography. Collectively, these layers can consume more than 10% of transaction value in some international scenarios, considerably reducing net revenue for fintech operators and merchants.​

Complicating matters are regulatory requirements such as the European Union’s PSD3 directive and PCI DSS 4.0 compliance, which increase operational costs by approximately 25% for multinational PSPs and fintechs. Siloed data from fragmented payment providers combined with manual reconciliation processes creates operational bottlenecks, with 60% of finance teams spending over 10 hours weekly on error-prone reconciliation tasks. These inefficiencies not only inflate staffing costs but also delay financial closes and elevate the risk of compliance penalties.​

Hidden Revenue Drains and Fee Leakage

Beyond visible fees, fintechs and PSPs face a silent margin-erosion problem from hidden revenue leakage. Up to 80% of leakage stems from unmonitored discrepancies, chargebacks, FX markup margins, and failed transactions that go undetected due to fragmented payment ecosystems. For example, e-commerce firms see roughly 70% of their costs driven by interchange fees, yet they frequently fail to capture lost fees from failed or duplicated settlements.​

Operational silos prevent comprehensive fee analysis and fraud detection, culminating in an estimated 1.5% of revenue lost annually to payment discrepancies and errors, according to Forrester Research. Complex cross-border workflows heighten this challenge, as currency conversions, delayed dispute resolution, and inconsistent audit trails prolong error detection by weeks, inflating manual investigation and correction workloads.​

AI and Automation as Solutions to Payment Cost Challenges

The constant pressure to reduce costs faced by Fintech companies and PSP companies has created opportunities for innovative solutions provided through AI and Automation, which revolutionise how these businesses operate. AI-powered reconciliation and transaction monitoring can automate over 90% of manual processes, freeing teams to focus on strategic work instead of repetitive reviews. Real-time and predictive analytics improve fraud and error detection, delivering instant insights into excessive fees, duplicate charges, and potential fraud. Together, these capabilities enable businesses to reduce operational costs by more than 30%.

Financing and operation teams can gain a comprehensive understanding of all payment activity when they use unified dashboards that provide integrated payment information from their PSP, their bank(s) and card networks. The complete picture allows for better-informed business decisions and improved authorisation rates (go up about 12% on average) and reduced leakage (decrease by 80% on average). No-code and low-code platforms expedite automation deployment and flexibility while optimizing transaction routing and fee negotiations. These intelligent systems enable the journey from payments as a cost center to payments as a profit driver, with reported productivity gains of up to 66% among adopters.​

Strategic Steps for Regaining Control

There are numerous strategies that leaders in the FinTech sector may implement as a means of reinvigorating their position concerning costs associated with payment methods while increasing the sort of efficiencies they can generate.

Such strategies include:

• Using AI to monitor transactions in order to: a) Identify excessive fees, b) Identify mismatched entries, c) Identify unusual behaviour patterns.

• Allowing for the identification of potential new efficiencies in the management of payment service providers (PSPs) and financial institutions (FIs), allowing for the negotiation of better payment terms, and pricing with regard to payment processors and financial institutions (FIs).

• Building analytic and orchestration capabilities embedded within payment solutions can help counter the encroachment of big technology and alternative payments through providing seamless, data-driven merchant experiences.

• Establishing KPIs such as reconciliation cycle time, error rates, and Days Payable Outstanding (DPO) clarifies payment infrastructure performance and can drive a 20–40% reduction in processing costs through automation and proactive process optimization.

In summary, Fintechs and PSPs are ditching manual processes and siloed data for integrated AI platforms that deliver real-time controls, slashing multi-layer fees, hidden leakage, and operational drag. This protects margins, boosts service, and fuels sustainable growth. AI promises 10-40% fee cuts and will drive payment ecosystem transformation. In 2025’s highly competitive environment, early adopters gain a strategic advantage by transforming payments from cost centers into performance-driven growth enablers, positioning themselves at the forefront of operational leadership.
