Revenue leakage is a silent profit killer for professional services firms. Studies suggest that firms lose 5-10% of potential revenue to leakage annually.
Common Causes of Revenue Leakage
1. Unbilled Time
- Work performed but not recorded
- Time entries forgotten or lost
- "Quick" tasks that add up over time
2. Under-billing
- Rounding down time entries
- Writing off legitimate work
- Fear of client pushback
3. Scope Creep
- Extra work without change orders
- Informal client requests honored
- Unclear project boundaries
4. Billing Errors
- Incorrect rates applied
- Missed expense reimbursements
- Invoice calculation mistakes
5. Administrative Delays
- Late invoicing reduces collection rates
- Disputed invoices due to poor documentation
- Time entries not submitted for billing
Measuring Revenue Leakage
To identify leakage, compare:
- Estimated vs. actual hours: Are projects taking longer than scoped?
- Recorded vs. billed hours: Is all tracked time being invoiced?
- Realization rate: What percentage of standard rates are you collecting?
Preventing Revenue Leakage
Strategies to minimize leakage:
- Real-time time tracking: Capture work as it happens
- Clear scope documentation: Define what's included and excluded
- Change order processes: Formal approval for out-of-scope work
- Regular billing cycles: Invoice promptly and consistently
- PSA software: Automated capture and billing workflows
- Manager review: Oversight of time entries and write-offs
The Cost of Leakage
For a firm with $5M in annual revenue, even 5% leakage means $250,000 in lost profit—often the difference between a good year and a great one.
