Fraud attempts are no longer quarterly anomalies. They arrive weekly, sometimes daily, alongside legitimate credit applications. The sheer volume makes manual spot-checks unsustainable. Many credit teams report encountering at least one fraud attempt per week. Managing this volume while maintaining approval speed for legitimate customers requires systematic processes, not gut instinct.

The Reality of Weekly Fraud

Attackers do not need sophisticated technical breaches. They use simple social engineering tactics: impersonating employees of well-known companies or creating look-alike domains. The primary vector is identity theft of valid businesses. The entity exists, the credit history is good, but the person applying has no connection to the company. Standard credit reports verify the business name but miss the fraudulent requester. This gap allows fake applications to pass through undetected.

The Existing Customer Loophole

Fraudsters bypass new customer onboarding by posing as existing customers. They know new accounts undergo scrutiny. Claiming to be an established buyer reduces verification checks. Common tactics: claim to be an existing customer, place large orders to create urgency, change the shipping address just before delivery. Red flags like slight changes in email domains and last-minute address modifications get missed when the focus shifts to fulfillment.

Why These Tactics Work

Process gaps create vulnerabilities, regardless of credit team skill level.

Verification Fatigue

Credit managers reviewing dozens of applications weekly cannot manually verify every email domain. Without automated systems flagging domain mismatches, errors slip through.

Separation of Sales and Master Data

Sales teams can modify shipping addresses or customer contact info without secondary credit review. Sales prioritizes volume. Credit prioritizes risk mitigation. When sales representatives handle verification checks, the conflicting priorities create exposure.

Static Credit Data

Traditional credit reports confirm financial health, not identity. A report shows payment history. It does not verify that the person emailing you has authorization to buy for that company.

A Systematized Defense Strategy

Effective fraud defense requires verification frameworks that address identity alongside creditworthiness.

Pillar 1: Domain and Digital Identity Checks

Every application should undergo a digital footprint check with two specific validations:

  • Domain Match: Does the email domain match the company's known web address exactly? Watch for typosquatting (e.g., construction-corp.com vs construction-corps.com).
  • Domain Age: Fraud rings register domains days or weeks before attacks. A domain created 14 days ago claiming to represent a 50-year-old manufacturing firm is an immediate red flag.

Pillar 2: The Change of Address Protocol

Last-minute shipping address changes indicate account takeover or impersonation.

The Rule: Any ship-to address change requested via email shortly before dispatch triggers an automatic credit hold. Release the hold only after verbal verification with a known contact on file (never the person requesting the change).

Pillar 3: Validating the Requester

Do not rely on the contact information provided in the application. Use public records or the company's main switchboard to verify employment. Call the company's main line and ask for the purchasing manager by name. This confirms legitimacy in minutes.

Strategic Impact of Systematization

Standardized verification workflows protect more than inventory.

Operational Efficiency

Investigating fake leads wastes valuable time. Filtering out fraudulent applications early allows credit teams to focus on real revenue opportunities.

Sales Confidence

Credit teams that catch fraud reinforce their value as strategic partners rather than deal-blockers.

Revenue Preservation

In low-margin industries, losing a single high-value shipment wipes out profit from dozens of legitimate deals.

Conclusion: Your Fraud Defense Checklist

Fraud attempts will continue weekly. Make handling them routine and safe.

Actionable Steps

  1. Audit your intake forms: Require business email addresses (no generic ISPs) for credit terms.
  2. Review verification protocols: Create scripts for calling main business lines to verify employees.
  3. Lock down master data: Prevent sales teams from changing shipping addresses on active orders without system flags or approval workflows.
  4. Automate domain checks: Flag email domains that do not match company web addresses or were registered in the last 90 days.
  5. Establish address change holds: Create automatic credit holds for shipping address changes within 48 hours of delivery.

Treating fraud defense as a process problem rather than a personnel problem builds systems that remain secure during high-volume periods.
