How Technical Debt in Code Attribution Systems Can Derail Your M&A Deal

When Technical Oversights Become Deal-Breakers in M&A

Imagine discovering a $100,000 accounting error days after finalizing an acquisition. That’s how technical debt feels in M&A deals. After 12 years reviewing acquisition targets, I’ve seen how minor-seeming issues in code attribution systems can expose serious risks.

Take our coin grading case study: What looked like one mislabeled coin revealed systemic problems. In tech deals, these “small” errors often hide bigger issues – unreliable code, shaky operations, and cultural blind spots that tank valuations.

The Attribution Failure That Mirrors Technical Debt

A Real-World Wake-Up Call

That frustrating coin mix-up? It’s eerily similar to what I find in acquisition targets:

• Time capsule code: Systems relying on decade-old logic (like those outdated Cherrypicker’s Guides)
• Knowledge gaps: Critical information locked in employees’ heads (sound familiar, @yosclimber?)
• Process black holes: Departments working in silos (hello, unreachable shipping department!)

“Their show expert says yes to it, and when it goes in with a note as to what he said they don’t give it to me” – Swap “expert” for “engineering team” and you’ve got classic post-acquisition finger-pointing

4 Make-or-Break Checks for M&A Technical Due Diligence

1. Code Quality: The Devil’s in the Error Handling

Repeated attribution errors despite clear rules? That screams poor exception management. Here’s what I look for:

// Warning Sign - Silent Failures
function attributeVariety(coin) {
  // Still referencing 1985 rules 
  const varieties = require('./old-guide.js'); 
  return varieties.find(coin) || 'Standard'; // Oops, no error logging
}

// Healthy System - Defensive Coding
import {LatestGuide} from '@verified-rules';
import {auditTrail} from '@monitoring';

export default async function attributeVariety(coin) {
  try {
    const result = await LatestGuide.identify(coin);
    auditTrail.log(coin.id, result); // Automatic paper trail
    return result;
  } catch (error) {
    notifyExperts(coin); // Fail-safe protocol
    return 'Needs Review';
  }
}

Deal killer: Systems that can’t self-correct when things go wrong

2. Scalability: What Breaks Under Pressure?

The grading company’s “fast submission” option that bypassed checks? I see tech equivalents daily:

• Throughput tripping over accuracy (that 9-day processing delay hid errors)
• Human bottlenecks (“Only Susan knows that system” = acquisition risk)
• Infrastructure crumbling under 2x normal load

Always ask: “Show me your performance metrics during last Black Friday-level traffic.”

3. Hidden Costs: When Quick Fixes Backfire

$200 FedEx labels to fix $20 errors? Classic symptom of patchwork systems. Watch for:

4. Culture: The Silent Deal Killer

Four service calls to fix one coin? That shows deeper issues:

• Teams passing the buck (“Not my department”)
• No automatic escalation paths
• Rewarding speed over accuracy

Pro tip: Ask engineers: “What happens when your monitoring system screams at 3 AM?” Their answer predicts integration headaches.

Your Action Plan for Better Tech Due Diligence

The 5-Point Inspection Checklist

Here’s the exact checklist I use when evaluating targets:

1. Follow error paths – do they self-resolve or explode?
2. Documentation audit – wikis or word-of-mouth?
3. Hotfix deployment times – hours or weeks?
4. Rollback capability testing
5. API version consistency checks

Valuation Math: Quantifying Technical Debt

Found problems? Adjust offers using this reality check:

Real Value = Asking Price × (1 - [
  (Untracked Errors × 0.15) +
  (Patchwork Fixes × 0.10) +
  (Knowledge Gaps × 0.20)
])

In our coin case, repeated resubmissions justified 12-18% price reduction. Tech debt deserves similar discounts.

Final Thought: Protect Your Investment

That misattributed coin wasn’t just a grading error – it was a warning. In M&A tech due diligence:

• Messy code = future integration nightmares
• Manual processes = hidden labor costs
• Siloed teams = cultural debt

Do the technical detective work upfront. Because discovering their systems can’t handle basic transactions post-close? That’s infinitely more costly than walking away from a bad deal.
