When should your agency hire a media buyer vs. outsource?

“How many clients before I hire a media buyer?” is one of the most-asked questions in agency circles — and the honest answer isn’t a number. It’s a utilisation question. Here’s a framework that actually decides it.

The wrong trigger: a busy week

Most agencies hire reactively, off a stressful month. That’s how you end up paying a fixed salary through the quiet months that follow. A single bad week is not a hiring signal.

The right trigger: sustained, predictable utilisation

A full-time media buyer makes sense when you can answer yes to all three:

1. Volume is steady, not spiky. You have enough consistent paid-media work to keep one person ~80% utilised for the next 6–12 months — through slow periods too.
2. Cash flow covers the fully-loaded cost. Not just salary — add 30–40% for tax, benefits, tools and management. Realistically $70k–$105k/yr.
3. You can manage and grow them. Hiring a specialist you can’t mentor or keep busy is how good people leave.

If any answer is “not yet,” outsourcing is the lower-risk call.

Why outsourcing usually wins earlier than you think

• No hiring lag. A white-label team is live in 24–48 hours, not a 4–8 week search.
• It flexes. Capacity scales up when you win a client and down when one churns — your cost tracks your revenue.
• No single-person risk. A team has backup; one hire doesn’t.
• Senior time back. Your best people return to strategy and sales instead of campaign builds.

A simple rule of thumb

Outsource execution until you have enough steady volume to keep a full-timer ~80% busy through a slow quarter. Hire when crossing that line is cheaper and lower-risk than staying flexible — and not a week before.

Many agencies never fully cross it, because a white-label layer lets them keep winning clients without ever carrying idle payroll. That’s the model behind Understory. Map your first offload or read how to scale without scaling payroll.
