Billable Hours
Billable hours are work hours that can be directly charged to a client or project. They represent time spent on activities that generate revenue for the organization, as opposed to internal or administrative tasks.
Key Characteristics
- Client-chargeable: Time that appears on client invoices.
- Project-specific: Usually tracked against specific projects or engagements.
- Revenue-generating: Directly tied to income for professional services firms.
Billable vs. Non-Billable Hours
Understanding the distinction is critical for profitability:
| Billable | Non-Billable |
|---|---|
| Client meetings | Internal meetings |
| Project work | Training |
| Deliverable creation | Administrative tasks |
| Client communications | Business development |

Retainer

Best Practices
- Track time in real-time rather than reconstructing at week's end.
- Define clear billable/non-billable categories upfront with clients.
- Review timesheets regularly for accuracy.
- Use time tracking software to automate capture and reporting.
