7 Ways Agencies Can Optimize Billable Hours

Okay, okay. Last month, how many hours did your team actually spend on client work?

Imma let you think it through…

You got the actual number? Great.

Now, tell me: how many of those hours made it onto an invoice?

Yeah… those two numbers don’t match, do they?

If that’s the case for you, welcome to the club. Almost every agency faces this issue, and it’s not because you’re all bad at math or because your people need to change how they work. It’s most likely those damn quick fixes, short calls, and extra rounds of feedback that never get a line on a timesheet.

You know what I’m talking about…

The account manager hops on a 7-minute client call.

The designer nudges a button radius “superquick”.

The copywriter double-checks a headline.

And they don’t log any of it. None of them thinks those tasks are worth logging, even though the work gets done and the client benefits. Hence, those minutes and hours end up in a vacuum between what you’ve done and what you billed.

That vacuum is what billable hours optimization for creative agencies is about. You want to get paid properly for the work you’re already doing, and catch overruns before they catch you.

‍So, we need to work on your tracking and billing, ‘cuz the work is happening (apparently). I’ll give you a simple 7-item list on how to optimize billable hours in an agency.

Each of those items is built for creative teams and comes with real agency examples. We’ll start with the small tasks that never make it onto timesheets, and talk about what you charge/don’t charge for, how you estimate, and all that jazz. It’s gonna be a fun time, for sure.

Let’s get to the actual fixes. Ready when you are 🫴

Key Takeaways:

• Small unlogged tasks, like quick calls and minor design tweaks, add up to many unbilled hours, so teams should capture them to get paid for work already done.
• Human memory is unreliable for time tracking, so automatic tracking that records activity in the background removes the need to remember what was done.
• Define what a revision round means in writing, budget for internal reviews, and price extra rounds so you bill for feedback work instead of absorbing it.
• Last-minute changes interrupt other work, so a rush policy in the contract, such as 1.5x for changes requested within 24 hours of a deadline, helps recover the cost.
• Research, client communication, and discovery are real work, so list them as separate lines in proposals and log them to make their cost visible.
• People underestimate how long tasks take (the planning fallacy), so estimate from tracked historical hours, give ranges, and ask the person doing the work.
• Review estimated, tracked, and billed hours for each project every week, and flag projects at 70-80% of budget so overruns can be fixed early.

#1 Catch the tiny tasks that never make it onto timesheets

I highly recommend you start here, because this is the leak you probably pay the least attention to.

Think about it.

On a random Tuesday, your team does a bunch of small tasks without logging any of it. Because they think, “No way this is worth recording.” And to be fair, they might be right—it’s not. But let’s zoom out for a second.

Say there are 6 people on a project. Each does 3 small tasks a day, and each takes 15 minutes. No one logs those tasks. When you do the math, that’s 4.5 hours of work daily, over 20 hours a week, on a single project that goes unlogged and unnoticed. For a month-long retainer, that can become a full week of unbilled work.

And that’s just for one single client. Multiply these numbers across your roster, and you’ll realize you’re missing one person’s salary. 

Even worse, imagine what the future holds. Like, if your records show a website project took 40 hours but it actually took 55, that 15-hour gap gets absorbed as unpaid labor, never showing up in revenue but showing up in costs (salaries and overhead). Then, you price the next similar project based on 40 hours, and the loss repeats. So, you end up underpricing your work again and again and again.

That’s why we at Memtime like to say it’s actually not that hard to find more billable hours in creative work: you don’t need to invent new hours, just remember the ones already worked.

And how do you do that when our human brain isn't built to remember every single thing we did throughout the week?

Well, you find something that remembers tasks for you. Like, a second brain, if that makes sense.

Something like Memtime.

Memtime records what your team worked on in the background: which apps and files they used, meetings they attended, sites they visited, calls they took, and so on with time stamps.

At the end of the day or week, your people can look back over a private timeline (called Memory Aid) and assign those blocks to the right client project (Memtime integrates with 100+ PM, billing, and accounting tools). Like, they can see that 10-minute banner fix, right there, with a timestamp and a file name attached to it.

Memtime is by no means a monitoring tool. Nobody is watching over anyone’s shoulder here. There are no screenshots or a manager dashboard showing what each person did minute by minute. Each person's timeline is private, and only the time they choose to assign to a client project is ever shared. That’s it.

Now, listen, Memtime is great, and you can try it yourself if you don’t believe me. 😉
But before you introduce yet another tool to your team, here’s what I’d do if I were you:

• Share how automatic time tracking helps (for billing). Explain to your team that every minute or hour that goes unrecorded is an hour you either absorb or underbill. Automatic tracking catches those minutes and hours, so your invoices reflect the work actually done, and you can back them up when a client asks questions.

• Make logging a daily habit. Five minutes at the end of each day is all it takes, since the timeline does most of the remembering for you.
• Normalize small entries. Tell your team a 10-minute edit is a valid, billable entry. If people think only big chunks of work count, minutes will disappear, and so will your revenue.
• Don’t expect a fully logged 8-hour day, every single day. It isn’t realistic, and it shouldn’t be the goal. Aim for a healthy, realistic share for your type of work and treat the rest as the normal cost of running a business.

#2 Treat feedback rounds & internal reviews as real work

Because they are real work!

Imagine this. The proposal says “2 rounds of revisions” but the client sends feedback and then more feedback. Then a stakeholder who wasn’t in the kickoff comments with a completely different direction. So, round 2 becomes round 5, and nobody counts the work around the feedback.

Someone has to collect the comments, reconcile contradictions, brief the designer, update the file, and prep the walkthrough.

Then goes the internal review.

The creative director’s pass.

The account manager’s check.

The proofread.
‍
Must I go on?

Each step feels like “just a quick look”, but it’s actually a big chunk of the job.

So, here’s what I want you to do:

1. Define what “a round” is in writing. For example, “One round means one consolidated set of feedback from one named contact, delivered in a single document or call.” Once you do that, 5 scattered Slack messages from 3 people count as 3 rounds, not 1.
2. Budget for internal reviews up front. For example, if you need a second copywriter’s edit for tone and consistency, plus a proofread, and since the client is in a regulated industry, a legal or compliance check, add those hours to the estimate. Follow this rule: if the hours are crucial to delivering good work, you charge for them.
3. Track feedback time as its own category. After a few projects, it's essential to see how long feedback really takes per deliverable. A brand identity might take 12 hours of feedback handling; a landing page might need 4. You need to know those numbers.
4. Cap and price the overflow. If 2 rounds of revisions are the standard, don't panic when round 3 arrives, and don’t absorb the cost. Say something like, “Happy to do another round! That’s 2 extra hours, and we’d add it to the next invoice.” Said kindly, most clients will just let it slide, and there’ll be no issues.

#3 Build a space for last-minute changes 

Imaginary scenario: it’s 4:47pm on a Thursday, and you get an email from a client: “Tiny tweak before tomorrow’s launch. Can we swap the hero image, rewrite the headline, and move the CTA?”
And you think to yourself, “Here we go again”, because deep down you know those last-minute changes are one of the most expensive hours in the agency, as they are often the least billed.

They interrupt other work, they’re rushed, and frequently come with overtime. But because the client is stressed and you genuinely want to help, those changes get away with being free.

If this scenario seems familiar, I urge you to create space for rushed changes. Here’s how to do so:

• Create a rush policy, and put it in your contract or SOW. Like, changes requested within 24 hours of a deadline are billed at 1.5x, or at a minimum a 2-hour block.
• Give your team a script. Junior designers and account managers shouldn’t have to negotiate under pressure. A simple line like this can save them: “Absolutely, we can do that. Let me confirm the extra time and get back to you in 15 minutes.” 
• Use a simple change request form. A short template will do just fine. Include what changed, why, hours estimated, and impact on timeline, and send it to your client.
• Log the interruption itself. When a change lands mid-task, the cost isn’t only the edit. It causes disruption to whatever the teammate was doing. Research on workplace interruptions by Gloria Mark and colleagues, discussed in this Gallup Q&A, found that people often take roughly 20 minutes to get back to the original task after being interrupted. It’s one field study, so treat the number as a rough guide, but anyone who’s been pulled off a task to fix something quickly knows the feeling.
• A tracked timeline (with Memtime) helps here. When the client later asks, “Why did this take so long?”, you can show that the work was interrupted, redirected, and redone, with receipts.

#4 Charge for research & thinking

Research is one of the sneakiest unbilled categories in a creative agency.

Just imagine a copywriter spending 2 hours reading competitor sites to nail the tone, or a designer building a mood board and testing 3 typographic directions before showing anything. They haven’t produced any output, and that’s why such research often gets overlooked or never gets recorded at all.

The result is a deliverable that looks quick, but the thinking behind it took a few days.
Here’s how to stop this:

• Make project discovery a phase, not a favor. Put “research and discovery” in your proposal as a separate line. Even a modest block of hours signals that thinking is part of the product, and clients who value good results usually understand this.
• Be specific about what research includes. Like, competitor audit, audience interviews, keyword research, content review, brand workshop, etc. You get the drill: just spell it out. No vague descriptions.
• Track research by project and task type. After 3 or 4 projects, check how long discovery really took for, say, a brand refresh vs. a campaign. You’ll see patterns like, you might find that research on B2B accounts runs 40% longer than on consumer ones. Memtime, interestingly enough, makes this step much easier: research is exactly the kind of work that happens across a dozen tabs, docs, and analytics dashboards, and Memtime records all of it in the background. Your team can look back at the timeline, assign those research blocks to the right client project, and later see in your reports how long discovery really took.
• Set a research timebox for fixed-fee work. If you’ve promised a flat fee, decide in advance how much time you’ll spend on research before the project starts losing money. 

Charging for research also has a quiet cultural benefit. When this part of a project shows up on your timesheets and is valued, your team stops feeling guilty about it. Creatives rarely say, “I spent 3 hours thinking”. Instead, they usually say, “I haven’t done much today.”  Logging time spent on research tells your team, and your clients, that thinking is part of the job.

#5 Estimate from what actually happened

You don’t know how to estimate tasks, even if you’ve done it a million times before. Yep. I said it.
And if it makes you feel any better, it’s because of your brain and the planning fallacy. It’s a whole thing, but the gist of it is that we humans tend to underestimate how long our own tasks will take, even when we know similar ones ran long before. Basically, you’re bound to estimate completion times optimistically, again and again, no matter how many times you’ve done it before.

That’s why I want you to only rely on accurate historical data:

• Build a library of real durations. For every project, compare estimated hours against tracked hours, task by task, like how long did a 5-page website really take, including feedback and QA. Memtime can help in this step because it records the small stuff, too (the feedback tweaks, the calls, the quick fixes), so the durations you pull for the next estimate reflect what the work really took, not what your people remember.
• Estimate in ranges. Instead of “20 hours”, say “16 to 24, depending on how much the client revises”.
• Ask the person who’ll do the work, then add a buffer. Account managers estimating for designers is obvi not a good practice. Get input from the designer or developer, then add contingency for the unknowns.
• Price from the data, not the competition. If your tracked hours show that a brand identity runs at 90 hours and you’ve been quoting for 60, no amount of efficiency will save you. You need to raise the price, narrow the scope, or both.

#6 Make account management & client comms visible

A big slice of agency work goes to conversation.

Kickoff calls, weekly check-ins, Slack threads, email threads, walkthroughs… ugh. Your most expensive people often do it, yet it usually doesn't show up on timesheets.

Why is that?

Well, it’s because comms feel like overhead. Your team is not doing the work; they’re just being responsive. Right?! Nope, wrong. If you want to optimize billable hours, you need to bring comms into the light.

Here’s how you can do so:

• Decide what’s billable and say so. Some agencies include a set number of hours for project management and client communication in every estimate, usually a percentage of the project, while others bill it as a separate line. Choose what works for you.
• Log calls as they happen. A 30-minute client call with prep and follow-up notes is really an hour. Your account manager knows that, and the timesheet should, too.
• Set communication expectations upfront. A short line in your onboarding doc helps, like “Includes 1 weekly check-in and email support during business hours. Additional calls are billed at our standard rate.”
• Don’t forget the internal meetings. The agency standup, the sync, and the creative review all belong to the project’s time if they were about that specific project. Even if you don’t bill it directly, you want to see it, because it affects profitability.

#7 Review estimated vs. tracked vs. billed every week

Lastly, we need to talk about the actual numbers.

Plenty of agencies track time, but fewer look at it often enough to do anything useful. Like, someone exports a report, spots a project that’s 40% over budget, and thinks, “Well, too late to fix it now.”

Weekly reviews change that.

Here’s a simple rhythm you can introduce to your agency:

• Every Monday, spend 15 minutes on 3 numbers per active project: hours estimated, hours tracked so far, and hours billed or billable. If tracked numbers are running ahead of estimates, start a conversation while there’s still time to fix it.
• Keep an eye on your recovery rate, too. Sometimes called realization, it’s the share of tracked value you actually invoice and collect. Here’s the catch: a team can have great utilization and still quietly lose margin because hours burn faster than planned or small extras never make it onto an invoice. That’s where your project burn rate helps—it shows how quickly a project’s hours are going out the door compared to the plan, so you can spot an overrun early, while you can still cut scope, renegotiate, or shift priorities.
• Flag projects at 70- 80% of budget. That’s your early warning. At that point, ask: Is the remaining work enough to finish within budget? If not, it’s time for a change order, a scope trim, or a client chat.
• Compare utilization by role, not just by agency. Your project managers and creative directors won’t hit the same numbers as your designers, and they shouldn’t. Look at targets by role.

Wrapping this up

I know this feels like a lot, so don’t try to implement everything at once. Pick two.

IMO, the best starting pair for most agencies is #1 and #7.

Get your team capturing the small stuff reliably, and start looking at the numbers weekly. Those two habits alone will show you the leaks you’ll want to fix with the other five.

Then, over a quarter or so, add in the rest. Define your rounds. Add a rush policy. Make discovery a line item. Build your estimating library. Be upfront about communication. All that good stuff.

And please remember: successful agencies aren’t necessarily the ones working their bums off, but the ones that know where every hour went and get paid for it. Sounds simple, ha?

FAQs

What are billable hours in a creative agency?

Billable hours are the hours you can charge a client for, such as design, copywriting, and project-related client calls. They differ from the hours your team is simply available to work. Billable hours are the starting point for invoicing and for measuring how much of your team’s time turns into revenue.

How do you calculate utilization rate?

Utilization is billable hours divided by available hours. For example, if someone is available for 40 hours in a week and 30 of them are billable, their utilization is 75%. Targets should differ by role, because project managers and creative directors won’t hit the same numbers as designers. Comparing utilization by role gives a fairer picture than just one agency-wide number.

What is the recovery rate (realization)?

Recovery rate, also called realization, is the share of tracked value you actually invoice and collect. It shows whether the work your team tracked turned into money. An agency can have strong utilization and still lose margin if hours overrun or small extras never reach an invoice. Tracking both numbers together shows where revenue is leaking.

What is the project burn rate?

Project burn rate shows how quickly a project uses hours compared to the plan. If hours are disappearing faster than expected, the project is heading for an overrun. That gives you time to cut scope, renegotiate with the client, or shift priorities.

Is automatic time tracking the same as employee monitoring?

No, not necessarily. Tools like Memtime record activity in the background, such as apps, files, meetings, websites, and calls, and show it to each person on a private timeline. Memtime doesn’t take screenshots, and it doesn't have a manager dashboard showing what each person did minute by minute.

Should my team log a full 8-hour day, every day?

No, that’s not really a realistic expectation. A fully logged 8-hour day isn’t doable, and it shouldn’t be the goal. Aim for a healthy, realistic share of billable time for your type of work, and treat the rest as the normal cost of running a business.
