Every agency puts a vast amount of energy into understanding how to budget for the work that goes out the door. Whether you’re using an ERP, Google Sheets, or API’s for days connecting an evolving tech-stack – billable time gets obsessed over. But what about the people who make sure the agency can function at all? That’s where the numbers get less attention than they deserve.

So, do we have a billable bias problem in our industry?

I would say so. Agencies are built around the billable hour, and even though every hour billed contributes to the total cost of running the business, the person generating it gets most of the attention. The agency charge-out rate is the very foundation of how most are structured, priced and evaluated. While that model makes sense for client-facing work, it creates a blind spot when it comes to the operational and business functions that hold everything together.

Finance teams, HR leads, ops managers, BDE’s, even the exec functions to an extent – none of these roles generate billable output in the traditional sense. So in a budget conversation anchored to billable utilisation, they can look like a cost rather than a contributor. That framing is fundamentally flawed, and it’s worth unpacking why.

What does “non-billable” actually costs you?

The idea that non-billable headcount is a drag on agency profitability misses something important. These functions don’t just support the business. In many cases, they protect it.

A Finance Manager who catches a cash flow problem before it becomes a crisis has just saved the agency from a potentially catastrophic situation. An HR lead who improves retention by even one or two people per year is saving tens of thousands of dollars in recruitment and onboarding costs. An Operations Manager who streamlines a workflow and recovers two hours per week across a team of twenty has just added the equivalent of a part-time resource to the agency’s capacity, at zero extra cost.

None of that value appears in a utilisation report, but it’s real, it’s measurable, and it belongs in the budget conversation.

The underinvestment trap

Here’s what typically happens in agencies that chronically underinvest in operational headcount: the work gets absorbed. Someone senior ends up doing tasks that shouldn’t be sitting at their level. Finance and HR become bottlenecks and are reactive rather than strategic. Operations runs on putting out fires, implementing workarounds and goodwill rather than proper systems.

The agency looks lean on paper, sure. But underneath the surface, there’s a massive hidden cost in lost efficiency, senior time poorly spent and a team that’s perpetually one busy period away from burning out.

The trap is that this kind of underinvestment is self-reinforcing. The problems it creates are diffuse and hard to attribute to a single cause, the connection between “we don’t have enough operational support” and “our margins are shrinking” never gets made clearly enough to prompt action. Just cast your mind back to the time before you employed your gun Ops Director, or a Finance Manager that just “got” the way the agency worked.

A better way to think about the budget

Rather than categorising headcount as simply billable or non-billable, progressive agency finance teams are starting to think about operational roles in terms of the leverage they create.

Questions to ask in collaborative budget rounds this season:

 – What does a Finance Manager enable the agency to do that it couldn’t do as effectively without them?

 – What does a Business Development lead unlock in terms of revenue potential as a percentage of all work?

 – What does a well-resourced People function protect in terms of retention and culture?

 – How does an agency know how much work it can safely take on without an Ops finger on the capacity pulse?

When you frame non-billable roles in terms of the value they enable and the risk they mitigate, the budget calculus changes. These aren’t costs sitting outside the revenue engine (remember they’re built in to the rate card) and they’re the infrastructure that keeps the revenue engine running.

Other questions worth asking this budget season

As you head into planning for the year ahead, these are worth sitting with:

Are the right people doing the right work, or are senior and creative staff absorbing operational tasks that belong elsewhere? What is your actual cost of turnover, and how does it compare to what you’re investing in the people function to prevent it? Where are the operational bottlenecks in your agency, and what’s the downstream cost of leaving them unresolved?

Budget with honesty about what it actually costs to run an agency well, and making sure the investment reflects the value these roles deliver every single day.
