Billable vs. Non-Billable Hours: How to Track and Sync in QuickBooks
Protect project profit margins, eliminate billing leakage, and streamline client invoicing with seamless QuickBooks TimeActivity synchronization.
Billable hours are employee work hours directly tied to client deliverables that can be invoiced, whereas non-billable hours cover internal overhead, administrative tasks, and general operations. Accurately categorizing and syncing these hours to accounting platforms like QuickBooks Online prevents revenue leakage and protects profit margins. Whether managed via TimeTrackerOn, Time Tracker On, or timetrackeron.com, automated tracking ensures every billable minute is captured against the correct client project code.
What Is the Difference Between Billable and Non-Billable Time?
Clear categorization is the first step toward accurate client invoicing and realistic margin calculations.
Billable Hours
Work directly performed for client contracts, milestone deliverables, or retainer agreements that can be transferred onto an invoice.
- •Client consultations, project kickoff calls, and strategy meetings
- •Direct execution (engineering, architectural drafting, design, copywriting)
- •Client-approved site visits, field inspections, and billable travel
- •Project-specific revision rounds and deliverable reviews
Non-Billable Hours
Internal labor and overhead activities necessary to operate your business, but not directly chargeable to an individual customer.
- •Internal team standups, all-hands meetings, and HR check-ins
- •Business development, RFP proposal authoring, and sales pitching
- •Internal software setup, system maintenance, and employee training
- •Unpaid meal breaks and administrative timesheet compilation
The Financial Impact of Untracked Billable Time
Billable leakage occurs when employees spend hours on client work without proper client and service item tagging.
When professional services firms or contractors fail to distinguish between billable and non-billable hours, billable leakage occurs. Employees spend hours on client work without proper client and service item tagging, making accurate invoicing impossible.
Even just 15 minutes of unlogged client work per consultant each day amounts to over 60 hours of lost revenue per year per employee. At a billing rate of $150/hr, that represents a $9,000 annual margin loss per employee. Moreover, unlogged non-billable time leads to distorted utilization ratios, causing leadership to miscalculate actual project profitability.
Accurate Utilization
Determine your team's real billable efficiency (billable hours divided by total capacity) to spot burnout and capacity bottlenecks.
Defensible Invoicing
Provide line-item transparent timesheet backing on client invoices to minimize billing disputes and speed up collections.
True Job Costing
Compare actual hours worked against estimated project budgets before fixed-fee contracts slip into negative margins.
