Billing Practices, Fees, and Revenue Extraction

Payment processing disputes often arise not from whether fees can be charged, but from how billing is implemented in practice and how charges are applied, calculated, and reflected within payment systems.

How Billing Diverges from Contract Terms

Fees are often described in high-level terms in merchant agreements but applied through automated systems that determine how charges are calculated, categorized, and deducted. Merchant funds may be systematically depleted over time through fees that are not clearly disclosed, not contractually authorized, or not tied to identifiable underlying costs. These charges are often applied through standardized billing systems and deducted directly from settlement proceeds and reserve balances.

The problem is compounded by how charges are presented. Rather than appearing as discrete line items, fees may be grouped into aggregated charges attributed to payment processing or third-party costs, including processing fees, chargeback fees, and related assessments, obscuring the distinction between pass-through expenses and amounts retained by the processor or platform. This lack of transparency can result in higher effective processing rates than the pricing reflected in the agreement, including increases in total fees despite declining transaction volume, changes in fee categories, or repricing that cannot be verified without detailed reconstruction.

Reporting Gaps and System-Level Distortions

Billing disputes also develop from the way systems track and report underlying activity. Platforms and merchants rely on dashboards and reporting tools to monitor disputes, transaction activity, and exposure. Where those systems underreport or fail to surface relevant activity, they can materially distort the perceived risk profile and financial position of the account. They affect how financial obligations are incurred by preventing merchants or platforms from identifying developing risk conditions while still allowing processors or card networks to assess fees, fines, or reserves based on activity not visible through standard reporting.

These issues often become apparent only after detailed analysis of merchant statements, reserve ledgers, and transaction-level data. That analysis reveals recurring categories of charges, including dispute-related fees, ACH reject fees, and “risk” or “penalty” assessments. It may also show multiple layers of fees applied to the same underlying activity, resulting in duplicated or inflated charges. A single disputed transaction, for example, may generate multiple fees across different categories or stages of processing, each applied automatically through the billing system.

Disputes frequently turn on how fees are calculated and how obligations are generated over time. The effective rate applied to a transaction may be determined by internal calculation logic rather than the percentage displayed to the merchant, including formulas that adjust the gross charge to achieve a target net amount. Processors and platforms may also track alleged deficiencies, minimum fee shortfalls, or other performance-based metrics through internal systems, carrying those amounts forward and later aggregating them into a single demand. These outcomes may also be driven by system errors or misconfigurations later corrected only partially or without explanation.

Residual Payments and Commission Disputes

Billing disputes in the payments industry often extend beyond pricing or fee disclosure. They frequently involve residual payments and commissions, which are often the most valuable component of the relationship between processors, ISOs, and agents. These disputes arise when one party disrupts or redefines the flow of revenue generated by merchant accounts, whether through termination, internal reallocation, or changes to how compensation is calculated and reported.

In many cases, agreements provide for ongoing residual payments tied to the performance of merchant portfolios, including after termination. Problems develop when those obligations are cut off or reduced based on asserted “for cause” terminations, alleged compliance issues, or interpretations of contractual provisions that were not intended to eliminate underlying economic rights. These disputes often reflect control over revenue streams originated and developed by the agent or ISO.

Disputes also arise in transactional contexts. When a processor sells its business or merchant portfolio, compensation rights tied to that portfolio may be triggered, including buyout provisions or continuing payment obligations that must be honored by a successor. Failure to disclose a pending sale, calculate compensation correctly, or provide the required election between lump sum payment and ongoing residuals can result in significant liability.

Other disputes involve the mechanics of payment. Residuals are typically calculated based on transaction volume, fees, and revenue allocations that are controlled by the processor. When reporting is incomplete, delayed, or inaccurate, the receiving party may be unable to verify whether it has been paid correctly. This lack of transparency often leads to claims for accounting, breach of contract, and conversion, particularly where funds continue to be collected but not remitted.

These disputes require reconstruction of the economics of the relationship. The central issue is how revenue is generated, how it should be allocated under the governing agreements, and where it has been diverted or withheld. In many matters, the dispute is not limited to unpaid commissions, but involves the wrongful capture of an ongoing revenue stream tied to a merchant portfolio.

Verification and Data Limitations

The issue is often not just the amount charged, but the inability to verify how the charge was derived. Charges may be assessed in the aggregate without sufficient detail to tie them back to particular transactions, accounts, or counterparties. Those problems are especially acute where one party bears financial liability for chargebacks, fees, or account deficits but does not have access to complete or timely information. Funds may be deducted or liabilities imposed automatically, without advance notice or an opportunity to mitigate or recover from the activity giving rise to the charge. The result is a structural imbalance in which financial responsibility is assigned without corresponding visibility or meaningful control.

Billing Audits, Retroactive Claims, and System Corrections

Billing audits and internal reviews present a related category of claims. Processors may conduct retrospective analyses that identify alleged underbilling over extended periods, often tied to system configurations, onboarding errors, or pricing assumptions. These audits can produce large, aggregated claims based on internal data that differs from the reporting available at the time of processing. Changes in reporting or system design, such as the removal of data fields, changes in how charges are displayed, or shifts in classification, can obscure material changes in pricing or revenue allocation and prevent clients from identifying issues in real time. In those circumstances, disputes arise not only over the amount claimed, but also over notice, transparency, and whether the system operated consistently with the governing agreements and the parties’ course of dealing.

Resolving these disputes requires reconstruction of transaction data, pricing logic, billing configurations, and account history, together with analysis of the governing agreements and the parties’ course of dealing. In many matters, the central issue is not whether a fee was disclosed, but whether the system used to calculate, track, and present financial activity operated in a manner that was accurate, consistent, and aligned with the parties’ agreements. Where those systems produce outcomes that cannot be reconciled with the governing agreements or the information made available to the client, they may form the basis for significant claims.

Approach to Billing and Revenue Allocation Disputes

Rome LLP represents merchants, platforms, ISOs, and other participants in high-value payment processing disputes involving billing practices, fee assessment, and revenue allocation within payment systems. The firm analyzes billing structures at the system level, develops claims based on improper charges, overbilling, and unsupported fee assessments, and pursues recovery through coordinated pre-litigation strategies and formal proceedings where necessary.

A significant portion of these matters is resolved before formal litigation. Brad Cebeci develops and structures claims based on billing practices and fee assessment, often identifying patterns of recurring charges across accounts or portfolios and coordinating recovery efforts across multiple counterparties. This work includes challenges to billing practices, reserve depletion, improper fee structures, and the development of class actions addressing systemic billing practices within the payments industry. Where disputes cannot be resolved through pre-litigation efforts, Eugene Rome leads complex litigation involving billing practices, contractual breaches, and coordinated conduct affecting payment relationships, including matters that have resulted in multi-million dollar recoveries and awards.

This work reflects how billing disputes arise and evolve within payment systems. It combines analysis of billing mechanics, structured claim development, and trial experience to recover funds and address systemic issues.
