How to Reduce Billing Write-Offs: A Data-Driven Approach

The Write-Off Problem

Billing write-offs silently drain law firm profitability. Industry data reveals:

• 10-15% of potential revenue lost to write-offs at average firms
• $50,000+ annual revenue loss per partner at mid-size firms
• 60% of write-offs are preventable with proper systems

This isn't an inevitable cost of doing business—it's a solvable problem.

Understanding Write-Off Categories

1. Pre-Bill Write-Offs

Time written off before invoicing due to:

• Excessive hours relative to task
• Work outside engagement scope
• Junior attorney inefficiencies
• Administrative tasks incorrectly billed

2. Post-Bill Write-Offs

Reductions after invoicing caused by:

• Client disputes over value
• Billing guideline violations
• Collection compromises
• Relationship-based discounts

3. Leakage (Never Captured)

Time that never makes it to a bill:

• Forgotten time entries
• Quick calls and emails not logged
• Research and preparation underreported

Root Cause Analysis

Before implementing solutions, identify your specific write-off drivers:

Track and Categorize

For 90 days, require categorization of every write-off:

• Client-requested reduction
• Billing guideline violation
• Over-budget matter
• Efficiency write-down
• Relationship accommodation

Identify Patterns

Analyze the data for patterns:

• Which timekeepers have highest write-off rates?
• Which clients request most reductions?
• What practice areas are most affected?
• When in the billing cycle do write-offs occur?
