Merchant Risk Management: How to Stay on the Right Side of the Risk Equation

Like any other endeavor, running a business involves a certain amount of risk. As a merchant, you’re constantly under the threat of potential financial, operational, and reputational damage. Understanding these risks and how to manage them is essential for protecting your business from disruption.

In this chapter, we discuss different types of merchant risk, distinguish between high- and low-risk merchants, and provide practical strategies for preventing fraud and managing chargebacks.

Types of Merchant Risk

Depending on a business’ age, vertical, size, and other factors, it can face dozens of risks simultaneously. Broadly speaking, though, merchant risk can be broken into three distinct categories:

Financial risk

Financial risk

Everything from fraud and chargebacks fees to lost inventory and cash flow disruption. As the one that most directly impacts your top and bottom line, financial is the most obvious type of risk.

Operational risk

Operational risk

Supply chain disruptions, technical glitches, human error, natural disasters… operational risk concerns the potential for things to go wrong in your day-to-day business.

Reputational risk

Reputational risk

The least obvious (and most insidious) of the three, reputational risk is the threat of damage to your brand’s image, which can be caused by anything from a data breach to negative customer reviews.

A rash of invalid chargebacks can increase all three types of risk

Low-Risk vs. High-Risk Merchant Categories

With the above in mind, there are also some forms of risk that are inherent to your industry, your history, your business model, or even your area of operation. Payment processors and acquiring banks will categorize your business as either low-risk or high-risk based on these qualitative factors.

Low-risk merchants generally deal in physical goods with low return or chargeback rates, such as clothing or books. These merchants may sell more to  large businesses or government agencies, which typically file fewer chargebacks.

High-risk merchants, on the other hand, often operate in verticals with higher fraud and chargeback volume, like travel, gaming, or subscription services. Being classified as high-risk usually means increased processing fees and stricter account requirements.

Fraud Prevention Strategies

No matter the risks you face, you'll probably need more than one type of prevention tool to keep the lion’s share of fraud at bay. Some “must-have” fraud prevention tools include:

3-D Secure 2.0

This advanced security protocol evaluates dozens of datapoints during the checkout verification process. Working in the background, it creates a frictionless payment experience while shifting chargeback liability away from you — and onto the issuer.

Machine Learning

Instead of using static, inflexible rules-based fraud prevention systems, machine learning (ML) solutions analyze vast amounts of transaction data in real-time to flag suspicious activity, identify and adapt to fraud, and block risky transactions.

Fraud Scoring

Assigning each transaction a numerical score can help evaluate threats at a glance. Fraud scoring quantifies the risk level of attempted sales based on factors like geolocation, order value, address verification service (AVS) data, and more.

Chargeback Prevention and Management

Deploying fraud prevention tools at checkout can help you deflect most fraud up front. That said, there will likely be some chargebacks that still come your way. That’s why you need a second layer of defense to help you respond to any post-transaction fraud that may arise:

Tip

Signing Up For Chargeback Alerts

Dispute alert services like Ethoca Alerts and Verifi CDRN notify you of imminent disputes before they escalate to chargebacks. You’ll have one final opportunity to resolve the issue directly with the customer and avoid a chargeback fee.

Tip

Implementing Clear Billing Descriptors

Sometimes, customers file chargebacks simply because they don’t recognize a legitimate charge. Clear billing descriptors that display your “doing business as” name (ideally with a phone number) can cut down on avoidable disputes.

Tip

Providing Best-in-Class Customer Service

Attentive and helpful customer service from representatives who are empowered to solve customer problems helps build trust in your brand. Customers who feel heard are also more likely to contact you before resorting to a chargeback.

While nearly all chargebacks are theoretically preventable, the defenses you put in place will help determine how many you actually end up dealing with.
