How eBay’s Counterfeit Crisis Exposes Critical Flaws in M&A Technical Due Diligence

When one tech company buys another, a thorough tech check is essential. Let me show you how a target company handles problems like counterfeit sales—it can make or break an M&A deal.

Why Scalability and Platform Integrity Matter

As an M&A due diligence consultant, I’ve watched platforms like eBay struggle with fake listings, seller fraud, and weak detection systems. These aren’t small issues. They point to bigger problems: technical debt, poor scalability, and shaky risk management. For any buyer, missing these during technical due diligence could sink a billion-dollar deal.

Code Quality: The Foundation of Trust

Strong code is non-negotiable for high-volume platforms. Take eBay’s counterfeit reports—like those 2025 Silver Eagles from China. They hint at flaws in automated checks and moderation. When I review a target’s tech, I focus on:

• How algorithms spot shady listings (think odd pricing or risky locations)
• How well code processes user reports and AI responses
• Connections to third-party verification services

If a platform leans too much on manual reviews—as eBay sometimes does—it’s a sign of poor scalability and higher costs.

Scalability: Can the Platform Grow and Fight Fraud?

Scalability isn’t just about more users. It’s about staying secure under pressure. eBay’s trouble with fakes, even after user reports, suggests possible bottlenecks like:

• Slow database queries delaying fraud detection
• Missing real-time analytics to spot patterns (e.g., fake items from one region)
• Outdated systems that can’t handle new threats

On one deal I worked, the target’s moderation tools couldn’t scale. The result? A 40% overhaul cost after acquisition.

Technology Risk: Measuring the Fallout

Every tech flaw has a cost. For platforms like eBay, counterfeit sales hurt trust and draw regulators. During due diligence, I weigh:

• Financial Exposure: Losses from chargebacks, lawsuits, or fines
• Reputational Harm: How public scandals (like viral fake item memes) damage the brand
• Technical Debt: The price to upgrade systems, like adding better AI moderation

Here’s a tip: Use risk scoring to prioritize issues. If fraud detection is weak, it might justify lowering the deal price.

How to Run M&A Technical Due Diligence

From my experience, here’s a simple way to assess a target’s tech:

1. Review the Code

Sample code for fraud detection (simplified):


# Pseudocode for listing validation
def validate_listing(listing):
if listing.price < threshold_value and listing.origin == "high_risk_region": flag_for_review(listing) else: auto_approve(listing)

Check for: Speed, false positive rates, and ties to machine learning.

2. Test Scalability Under Pressure

Simulate busy times (like holiday sales) to see if fraud systems hold up. Tools like Apache JMeter can benchmark performance.

3. Study Past Incidents

Look at historical data—like user reports of counterfeits. If AI keeps missing fakes from certain areas, the training data might be flawed.

From Red Flags to Green Lights

Technical due diligence isn’t just about finding flaws. It’s about judging if a target can fix them. Even with eBay’s counterfeit issues, it could be a good buy if it shows:

• Awareness: Admits problems and has a plan
• Scalable Tech: Modern architecture that allows quick upgrades
• Risk Control: Strong protocols for fraud and user reports

In M&A, the tech details decide everything. By zeroing in on code, scalability, and risk, buyers can integrate smoothly and find real value.
