In the shadows of every finance department lurks a persistent threat—one that doesn’t announce itself with alarms or suspicious packages but rather arrives disguised as legitimate business.
Financial fraudsters don’t kick down doors waving guns and demanding money. They slip quietly through gaps in processes and controls, exploit procedural blind spots and leverage our innate trust in established systems. While headlines reasonably focus on sophisticated cyber-attacks, the sobering reality is that traditional fraud schemes haven’t disappeared.
Today’s organizations face a dual threat: “old-fashioned” fraudsters who continue to exploit manual processes and paper-based transactions, alongside tech-savvy criminals leveraging digital vulnerabilities. The danger lies not just in overlooking emerging threats, but in neglecting the persistent risk of traditional schemes that continue to rob businesses annually.
Consider this troubling paradox: despite massive investments in cybersecurity, many organizations maintain surprisingly vulnerable financial operations. Disparate, manual vendor onboarding processes remain commonplace. Paper checks—each one a potential fraud vehicle—still represent some 40% of B2B payments. Approval workflows often rely more on institutional habit than deliberate design.
These persistent gaps explain why check and vendor fraud continues to thrive despite our technological advances. According to a study by the Association of Financial Professionals, 66% of organizations experienced actual or attempted payment fraud in recent years, with checks remaining a common target of attack.
The uncomfortable truth that seasoned financial professionals understand is this: comprehensive fraud protection requires addressing both traditional vulnerabilities and emerging threats. Organizations fixated solely on cyber attacks while neglecting foundational controls create dangerous blind spots that fraudsters are ready to exploit.
How do forward-thinking organizations build multi-layered defenses that address both worlds?
Rethinking Supplier Onboarding: From Vulnerability to Fortress
The traditional supplier onboarding process is a patchwork affair involving personnel across different departments, inconsistent documentation and information scattered across spreadsheets and email chains. This fragmentation means inefficiency, errors and incomplete vendor data.
Forward-thinking organizations have recognized that a supplier gateway represents their first and perhaps most critical line of defense. By centralizing and automating this process, they’ve transformed a vulnerability into a fortress.
What does this transformation look like in practice?
A unified digital portal becomes the sole entry point for all vendor relationships. It provides consistency and efficiency in vendor onboarding and enforces data completeness through required fields.
Further, a well-designed portal doesn’t just collect information—it verifies and validates it. Tax identification numbers are cross-referenced against the IRS database. Company addresses are geocoded and analyzed. Ownership details are scrutinized for connections to employees or existing vendors. And vendors are screened against sanction and barred parties’ lists.
This centralization creates a more efficient, consistent process than legacy vendor onboarding processes and contributes to an accurate vendor master file, while providing institutional documentation. When the accounting manager who’s intimately familiar with how things work (or are supposed to) leaves, the process knowledge doesn’t walk out the door with them. The centralized and automated vendor onboarding system replaces the process map that only existed in the manager’s head.
The Death of Paper? Why Checks Persist Despite the Risk
Despite overwhelming evidence of their vulnerability, paper checks continue to flow through American businesses at a staggering rate—nearly 3 billion per day. While this is down considerably from 20 years ago, checks remain the payment method for a significant percentage of B2B transactions, creating an enormous attack surface for fraud. Indeed the FBI warns against check cooking (aka baking), a next level check fraud using digital tools to produce counterfeit checks.
Why this persistence? For some, it’s the tyranny of the status quo—organizations cling to familiar processes despite their flaws. Many organizations have converted to ACH and other methods but still issue checks to a percentage of vendors.
But electronic payment systems are remarkably accessible. ACH systems can now process payments in near real-time. Virtual card platforms allow organizations to generate single-use payment credentials with preset spending limits. Even blockchain-based solutions are finding footing in some finance departments.
Beyond security, electronic payments offer unexpected benefits: automatic reconciliation, cash flow visibility and often significant rebates or rewards that can transform the accounts payable department from a cost center to a revenue generator.
Organizations that have made the transition typically wonder why they waited so long. As one CFO told me, “We spent years agonizing over the switch away from checks. Six months after making the change, we couldn’t imagine ever going back.”Be warned: check fraud is still a thing. And while there are several ways to guard against it, including everything from physical protection of stock, segregation of duties, check safety features and positive pay, the best way to avoid check fraud is to quit writing checks.
Building Digital Fortifications: The Technical Architecture of Fraud Prevention
In medieval times, castle designers understood that a single wall, no matter how thick, could provide absolute security. Instead, they created layered defenses—moats, outer walls, inner walls and castle keeps—each designed to slow attackers and provide multiple opportunities for defense. Modern fraud prevention requires the same thinking.
Technical controls are essential elements in fraud defense:
- Multi-factor authentication
- Encryption
- Audit logging
- Dynamic authorization controls
Multi-factor authentication ensures that credentials alone aren’t enough to gain system access. But that’s just the beginning. Sophisticated encryption protects financial data both in motion and at rest, rendering it useless even if intercepted. Comprehensive audit logging creates digital breadcrumbs that allow security teams to reconstruct the precise sequence of events surrounding any suspicious activity.
Perhaps most important is the implementation of dynamic authorization controls. Rather than static permissions, these systems evaluate contextual factors—time of day, geographic location, device characteristics and behavioral patterns—to determine whether a particular action should be permitted. An employee who typically processes 10 vendor payments per day suddenly initiating 50? The system flags it for additional verification.
These technical controls don’t exist in isolation from business processes—they’re deeply intertwined. When a vendor requests a bank account change, the system doesn’t just record the new information; it triggers a verification workflow, for example, requiring a verification phone call to an established vendor contact before the change takes effect.
The Critical Control: Bank Account Verification
The bank account sits at the heart of payment fraud. Nearly every scheme, whether sophisticated or crude, ultimately aims to divert funds to an account controlled by the fraudster.
This makes bank account verification perhaps the most critical control in your arsenal—and yet it’s often the most overlooked.
Effective verification goes beyond simply confirming that an account exists. It verifies ownership, establishing that the account belongs to the entity you intend to pay. It leverages bank account verification services that confirm the account and routing numbers and that the named account holder matches your vendor records.
For high-risk or high-value relationships, some organizations implement periodic reverification protocols, confirming account details even for established vendors on a rotating schedule.
The most effective systems combine automatic verification tools with human judgment. When a vendor’s banking details change shortly after an email account compromise is detected, even if all the verification checks pass, a thoughtful phone call using independently sourced contact information can unveil a sophisticated fraud attempt.
Humans on the Ramparts: Training Matters
Technical systems, no matter how robust, have a fundamental limitation: they can be circumvented by social engineering. A convincing phone call from someone claiming to be the CEO can override careful procedures. A well-crafted phishing email can extract credentials from even cautious employees.
This is why the human element cannot be ignored. Regular training sessions keep fraud awareness front of mind. Simulated phishing attempts help employees recognize the increasingly sophisticated tactics used by fraudsters. Clear escalation procedures ensure that suspicious requests receive appropriate scrutiny.
The most effective training doesn’t just tell employees what to watch for—it helps them understand the psychology behind fraud attempts. It explains why urgent rush payments are red flags. It clarifies why seemingly innocuous information might be used in social engineering attempts.
Some organizations have implemented “fraud moments”—brief discussions of real-world fraud attempts—at the beginning of team meetings. These casual conversations normalize vigilance and create a culture where questioning unusual requests is encouraged rather than penalized. Others avail themselves of outside resources and certification to further staff training and awareness.
Bringing It All Together: An Integrated Approach
While each of these elements provides value individually, their true power emerges when they work in concert—when your centralized vendor onboarding system automatically feeds screened and verified vendor information to your payment platform, when your technical controls enforce your business rules, when your well-trained staff understands both the “how” and the “why” behind your fraud prevention protocols.
This integration doesn’t happen by accident. It requires intentional design, cross-functional collaboration and leadership that recognizes fraud prevention not as a cost, but as a strategic investment that protects both financial resources and organizational reputation.
The organizations that excel at fraud prevention don’t just implement solutions—they create ecosystems where each element reinforces the others. Fraud prevention isn’t a project with an end date, but an ongoing program that evolves alongside threats.
In this evolutionary arms race, the advantage goes to those who build not just individual countermeasures, but comprehensive defense systems that address both traditional vulnerabilities and emerging digital threats.
It’s an asymmetric contest. A given fraudster only has to be right once; your organization must be right every time. A layered approach provides you the best protection.
