Non-billable time at agencies: what to do about it
What non-billable time actually is, the four categories that matter, what a healthy ratio looks like, and the levers that turn non-billable hours into either fewer hours or more billable ones.
Part of the time tracking guide
Non-billable time isn't waste - until you can't see it
Every agency has non-billable hours. They're not the problem; invisible non-billable hours are. When you can't see them, you under-price (assuming your team is more productive than they are), over-promise (assuming there's capacity that isn't there), and burn out (because somebody is absorbing the gap unsung). Visible non-billable hours, by contrast, are a planning input you can act on.
The agencies running well don't have zero non-billable time - they have a clear picture of where it goes and which slices to attack.
The four categories that matter
Lumping everything non-billable into one bucket is the second mistake. Split it four ways:
1. Essential overhead. Admin, payroll, accounting, internal meetings that the team genuinely needs. Roughly 10-15% of paid hours is normal; below that you're under-running the business, above that you're drowning in process.
2. Internal investment. Training, R&D, the agency's own marketing and content. This is the most under-counted category and the most valuable - it's how the agency gets better, not just how it ships.
3. Bench time. Paid hours with no work against them. Bench time is pure cost, and the best signal that capacity planning is off. A little is normal; consistent bench means hiring is ahead of pipeline or pipeline is shrinking.
4. Unbillable delivery. This is the killer one. Rework caused by vague scope, scope creep absorbed for free, fixing things that should have been caught earlier. It looks like billable work to the person doing it - and the client didn't pay for any of it.
Track each separately and the action plan tells itself.
What a healthy ratio looks like
There's no universal target, but useful ranges:
- Billable / total hours: 65-85% for delivery roles, lower for ops/management. See what is a good agency utilization rate.
- Essential overhead: 10-15% of total paid time.
- Internal investment: ideally 5-10% (and often 0% in struggling agencies - which is why they stay stuck).
- Bench time: under 5% in healthy weeks; trending up is your earliest warning sign.
- Unbillable delivery: ideally under 5%; over 10% is a scope or pricing problem in disguise.
Watch the trends weekly, not the absolutes monthly. The trend is the signal.
The levers that move it
Each category responds to a different lever:
Cut essential overhead by automating the same-every-week admin and removing meetings that don't have a decision behind them.
Protect internal investment by ring-fencing it on the calendar - the agencies that grow capability are the ones where this isn't the first thing skipped when busy.
Reduce bench time with better capacity planning - matching pipeline to capacity so people don't sit idle for a week between projects.
Kill unbillable delivery by tightening scope of work, treating scope changes as change orders, and improving briefing so rework drops at source.
The data tells you which lever to pull
Without accurate time tracking, all four categories blur into one "we're busy" feeling and you can't tell what to fix. With the data, the priority is obvious - the biggest non-billable slice is where the lever is. See the time tracking guide for how the whole picture fits.
Frequently asked questions
What counts as non-billable time at an agency?
Any hour the team is paid for that isn't billed to a client. Split it four ways: essential overhead (admin, payroll), internal investment (training, R&D, marketing), bench time (paid hours with no work), and unbillable delivery (rework, scope creep absorbed for free).
Is non-billable time bad?
Not inherently - some is essential (admin, training, internal investment). What's bad is invisible non-billable time: when you can't see where it goes, you under-price, over-promise and burn out. Visible non-billable time is a planning input.
What's a healthy non-billable percentage for an agency?
For delivery roles, aim for 65-85% billable (so 15-35% non-billable). Within the non-billable: roughly 10-15% essential overhead, 5-10% internal investment, under 5% bench time, under 5% unbillable delivery. Watch the trend more than the absolutes.
How do I reduce non-billable delivery work?
That's almost always a scope or briefing problem in disguise. Tighten the SOW, treat changes as change orders rather than freebies, improve briefing so rework drops at source. The fix is upstream from time tracking.
