Frequently Asked Questions on Billable Utilization
Why do freelancers lose 10% to 18% of billable hours?
Ad-hoc client syncs, discovery follow-ups, and calendar blocks that run 15 minutes over rarely get typed into manual timers like Harvest or Toggl. Auditing directly from Google Calendar recovers 3 to 5 billable hours per week automatically.
How does 6-minute (0.1 hr) or 15-minute (0.25 hr) duration rounding work?
Standard legal and consulting engagements round calendar blocks up to the nearest 6-minute (tenth of an hour) or 15-minute (quarter-hour) increment. ChronoSheet Pro performs this rounding automatically across every matched client event.
