Billable Hours at a Marketing Agency: How They Work and What They Mean for You
Billable hours are the hours you spend on work a client pays for. At a marketing or ad agency you log your time against each client and project, and the agency uses those hours to price its fees, staff accounts and check whether each piece of business makes money. Your utilization, the share of your hours that are billable, is often one of the things your manager watches.
Key takeaways
- Billable hours are the hours an agency employee spends on work a client pays for, logged against that client and project on a timesheet.
- Utilization is the share of your working hours that are billable, and agencies set targets for it that usually fall as you get more senior.
- Agencies use timesheets to price fees, staff accounts and see whether each client is profitable, even when the client pays a fixed retainer.
- Non-billable time such as pitches, internal meetings and training is normal and expected, but it still has to be logged honestly.
- In an agency interview, it's fair to ask about the utilization target, how timesheets are used in reviews and how overservicing is handled.
If you’re coming from an in-house job, timesheets can feel like a strange new habit. They’re less about watching you and more about how an agency knows what its work costs. Once you understand that, they become useful information about your job.
(Law firms and accounting firms bill hours too, often directly by the hour. This page is about how it works at marketing, advertising, PR and digital agencies.)
What are billable hours?
Billable hours are the time you spend on work a client is paying for: writing the copy, building the media plan, pulling the report, sitting in the client’s status call. Non-billable hours are everything else: pitching new business, internal meetings, training, agency admin, and time off.
| Usually billable | Usually non-billable |
|---|---|
| Client meetings and status calls | New-business pitches |
| Strategy, creative and media work on a client project | Internal all-hands and team meetings |
| Reporting and analysis for a client | Training and conferences |
| Project management for client work | Agency marketing and recruiting |
| Revisions the scope of work covers | Holidays, vacation and sick time |
Every agency draws the line a little differently, so the first week at a new agency is a good time to ask your manager which codes to use for what.
How do billable hours work at a marketing agency?
You log your time each day or week against a client and a job code, usually in a time-tracking or agency management system. The agency then compares those hours with what the client pays.
Agency fees are commonly built on labor: the hours of each role a client needs, multiplied by a rate. The ANA’s agency compensation research has found that labor-based fees remain the dominant way advertisers pay agencies, even as some large advertisers move toward fixed or output-based fees. An ANA guide to labor-based pricing describes how an hourly rate is built: salary and benefits, plus overhead, plus profit, divided by the hours a full-time person is expected to work in a year.
That’s why your timesheet matters even if you never see a client invoice. It’s the data the agency uses to:
- Price new work. Next year’s fee or the next project estimate is based on how long similar work took.
- Staff accounts. If a client’s hours run over, the account is either understaffed or overserviced.
- Check profitability. An account that takes far more hours than its fee covers loses money.
- Prove value to the client. Some contracts include regular reports of hours by role.
Retainers, project fees and SOWs
How a client pays changes how your hours are watched, not whether you log them.
| How the client pays | What it means | What it means for your hours |
|---|---|---|
| Retainer | A fixed monthly fee for an agreed amount of ongoing work | Hours are tracked against the retainer to spot overservicing and to reset the fee |
| Project fee | A set price for one piece of work, like a campaign or a website | Hours are tracked against the estimate; overruns eat the agency’s margin |
| Time and materials | The client pays for hours actually worked at agreed rates | Your hours go more or less straight onto the invoice |
| Commission or media fee | A percentage of the media spend the agency manages | Hours are still tracked to check the account covers its costs |
The scope of work (SOW) is the document that says what the fee covers: deliverables, rounds of revisions, meetings and often the hours by role. When a client asks for something outside it, that’s scope creep, and the account team either absorbs it, trades it for something else, or writes a change order.
What is a utilization rate?
Your utilization rate is the share of your available working hours that are billable. If you work 40 hours in a week and log 30 to client jobs, your utilization that week is 75%.
Agencies set utilization targets by role and level. Junior people doing hands-on client work usually have the highest targets; directors and leaders have lower ones, because more of their time goes to managing people, new business and running the agency. There’s no industry-wide standard number, so ask for the target in the role you’re interviewing for.
A target is a planning number, not a cap on how long you work. If you’re consistently far above it, the account probably needs more people, and that’s a conversation worth having with your manager.
How should you track your hours?
Log time the same day, in small blocks, against the right job code. Reconstructing a week on Friday afternoon is how hours go missing, and missing hours make an account look cheaper to run than it is.
- Keep a running note of what you worked on as you go, then enter it at the end of the day.
- Use the agency’s codes as they’re meant to be used. Logging a pitch to a client code hides the real cost of both.
- Log the real number, including the extra two hours a revision took. Under-logging to look efficient means the next estimate will be too low, and you’ll be the one short on time.
- Ask when you’re unsure whether something is billable. Your account lead or project manager will know.
If logging time feels like a chore, that’s normal for the first month. It quickly becomes a habit, and many people find it helps them see where their week really went.
How do billable hours affect your job and reviews?
At many agencies, utilization is one of the numbers your manager looks at, alongside the quality of your work, client feedback and how you work with the team. Consistently low billable time can mean you need more client work assigned; consistently high time can mean burnout risk.
What good managers do with the numbers:
- Rebalance workloads when one person is carrying an account.
- Push back on scope when a client’s asks outgrow the fee.
- Make the case for a new hire when an account’s hours keep running over.
If you’re in a review and the conversation turns to your hours, bring the context: which accounts ran over and why, and what you’d change. That turns a number into a conversation about the work. Our agency life guide covers how to spot an agency that manages workload well.
What should you ask about billable hours in an agency interview?
It’s completely fair to ask how an agency uses time tracking, and the answers tell you a lot about the culture. Put them in your own words; you’re trying to understand how the place really works, not quiz them.
What's the utilization target for this role, and how is it used in reviews? How do teams handle it when a client asks for work outside the scope? How often do accounts run over their hours, and what happens when they do? Are pitches and internal projects staffed on top of client work, or planned into people's time?
A healthy answer sounds specific: a target, a process for scope changes, and an example of a time they reset a fee or added a person. A vague answer is a cue to ask current or former employees what the hours are really like. The questions to ask at the end of an interview guide has more.
Do in-house marketers track billable hours?
Usually not. In-house teams work for one company, so there’s no client to bill. Some in-house agencies and shared creative teams do track time, to charge other departments or to show how their hours are used. Our in-house vs agency marketing guide covers the other differences.
FAQ
How many billable hours are in a year?
It depends on the agency’s working-hours standard. A 40-hour week over 52 weeks is 2,080 hours before holidays and vacation, and the ANA’s guide to labor-based pricing notes 1,800 to 1,875 hours as a typical full-time standard used to set rates. Your billable hours are the share of those spent on client work.
Do you get paid for non-billable hours?
Yes, if you’re a salaried employee. Billable and non-billable describe how the agency accounts for your time, not whether you’re paid for it. Freelancers are different: they usually only get paid for time a client is billed for.
What is overservicing?
Overservicing is when an agency does more work for a client than the fee pays for. It shows up as hours running over the scope, and it’s one of the main reasons timesheets exist. Small amounts are common to keep a client happy; a lot of it, for a long time, usually means long hours for the team.
Is a high utilization rate good?
Up to a point. Meeting your target shows you’re busy on client work, but running far above it week after week usually means too much work for too few people. Talk to your manager before it turns into burnout.
Why do agencies track time if the client pays a fixed fee?
Because the fee was based on an estimate of hours, and the agency needs to know if the estimate was right. Time on a retainer shows whether the account is profitable, whether it needs more people, and what to charge when the contract renews.
