What Billable Utilization Means at an MSP
Billable utilization is the share of a technician's available hours that land on client work in your PSA. It is the link between your payroll and your margin: every hour a technician is paid for but not working for a client is paid out of the profit on your agreements. The KPI version, with how to calculate it and where to aim, lives on Technician Billable Utilization.
At an MSP, billable does not always mean invoiced. Most of your work is covered by flat-fee agreements, so an hour on a managed client's ticket is billable to the agreement even though no one gets a separate invoice for it. Decide up front whether you count that time, or only time that produces an invoice line, and never mix the two across technicians.
What Counts and What Does Not
Write the rules down before anyone compares numbers, because the metric rewards whoever logs most generously.
| Usually counts | Usually does not count |
|---|---|
| Tickets for managed clients under an agreement | Internal IT for your own MSP |
| Project work and billable hours for block clients | Training, certifications and team meetings |
| Onboarding work for a signed client | Presales scoping for a prospect |
| Scheduled maintenance you perform by hand | Writing internal documentation |
The excluded work is not wasted. Documentation and training are how the next technician resolves the same issue faster. They just belong in a separate bucket so you can see how much of the week they take.
Why Too High Is a Problem Too
Low utilization means you are carrying idle capacity or that tickets are not being logged. High utilization looks efficient, but a technician with no unlogged time has no room for training, runbooks, or the next client you sign. It is often the early sign that you need to hire, which the answer on when to hire your first technician covers.
Read utilization beside other service numbers. If utilization rises while endpoints per technician stays flat, your stack may be generating more tickets than it should. If it rises alongside a falling effective hourly rate, you are working harder for the same agreement revenue, which usually points to underpriced contracts.
Using It Without Gaming It
- Measure against available hours, not a nominal full-time week, so leave and holidays do not drag the figure down.
- Review it monthly per technician and per team, not ticket by ticket.
- Pair it with quality measures so logging more time is never the easiest way to look good.
- Use the staffing calculator to turn a utilization change into a hiring decision.
For the target range and how it differs by role, see what technician utilization should be rather than a single rule of thumb.
Common Questions
Should the service manager have a utilization target?
Usually a lower one or none at all. Their job is to keep the team productive, so their own logged hours say little about how well they do it.
Does travel time count as billable?
Only if your agreement or invoice treats it as billable. Pick one rule, write it into the time entry policy, and apply it to every technician.
How do I get technicians to log time honestly?
Make time entry part of closing a ticket and review it weekly without blame. Utilization used as a punishment teaches people to pad entries.
