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 |
