Overview
Agencies report capturing 15-20% more billable time when switching from manual time tracking methods to automatic or memory-based time tracking systems. This represents substantial revenue recovery from work that was previously performed but not captured or billed.
The Lost Billable Hours Problem
Traditional manual time tracking suffers from:
- Forgotten Entries: Small tasks not logged immediately are forgotten
- Rounding Down: Workers underestimate time spent on tasks
- Switching Overhead: Time spent toggling timers isn't captured
- Micro-Tasks: Brief but billable activities fall through cracks
- Context Reconstruction: Difficulty remembering what was done when
Why 15-20% is Lost
Forgotten Work:
- Quick client emails and calls
- Research and preparation time
- Revisions and small edits
- Internal collaboration on client projects
- Administrative tasks related to deliverables
Psychological Factors:
- Reluctance to track "small" amounts of time
- Rounding to convenient intervals (e.g., 0.25 hours)
- Forgetting to start/stop timers
- Guilt about billing for certain activities
Process Inefficiency:
- Manual entry creates barriers
- End-of-day reconstruction is inaccurate
- No prompts for untracked time
- Difficult to verify what actually happened
Automatic Tracking Solutions
Desktop Activity Tracking (like RescueTime, Timing):
- Records all application and document usage
- Creates timeline of actual work
- Categorize time retroactively
- Captures everything automatically
Memory-Based Tracking (like Memtime, Timely):
- Builds complete activity log
- Review and assign time later
- No need for timers
- Captures all work performed
Smart Reminders (like Daily, Timeular):
- Prompts when untracked time detected
- Reduces forgetting
- Creates accountability
- Easy entry when reminded
Financial Impact
