The decision to outsource media buying usually arrives as a problem, not a plan: an agency wins a retainer client who then asks who runs their ads. There are four honest answers — turn it down, give it to someone junior and hope, spend three months hiring, or use a delivery partner.
The decision is usually made in week one of a panic. It should be made in advance, on arithmetic.
The number that decides whether to outsource media buying
Count the accounts you would be running six months from now, not today. A full-time senior buyer is a fixed cost whether you have three accounts or eleven. Divide their total cost — salary, on-costs, tools, recruitment, the ramp-up quarter — by the accounts they would realistically carry.
If that per-account figure is comfortably below what a delivery partner charges, hire. If it is above, you are paying for a bench. The agency vs in-house calculator does the sum with the costs people forget in it.
Most agencies compare a salary to a retainer. That comparison always flatters hiring, because a salary is the smallest part of what an employee costs.
Four signals you have waited too long
- One person knows every account. Their resignation is now a business risk, not an HR event.
- Your buyer has stopped doing creative testing. First thing to go when someone is overloaded, and the first thing that shows up in results three months later.
- You are turning down paid work because you cannot staff it. That is revenue you have already earned and are refusing.
- Reporting is late. Nobody is late on reporting when they have time.
When hiring is clearly right
Paid media is your core offer and will be for years. You have enough accounts to fill a full-time role today, not hypothetically. You can absorb three months of ramp-up. And you can keep the person — which in a market where good buyers are actively recruited is the part most agencies are too optimistic about.
When a partner is clearly right
Your book is lumpy. You sell strategy, design or SEO and paid is an attachment rather than the core. You need capacity this month. Or you want to test whether a service line works before committing a salary to it.
Per-account pricing flexes with your book. Win four accounts in a quarter and the cost rises with the revenue; lose two and it falls the same month. That is the whole argument, and it is a good one for an agency whose client list moves.
The option nobody considers: say no
Taking paid media you cannot deliver well is worse than declining it. The client notices within a quarter, and you lose the retainer you were actually good at as well. We turn down work for the same reason and it has never cost us a relationship.
What to do this week
Write down the accounts you expect in six months and run the cost comparison honestly, including recruitment and ramp. Then decide once, in writing, before the next client asks. Deciding in advance is the whole trick — the answer is rarely difficult, but it is almost always reached too late.
If a partner looks like the answer, the partner program explains the two models, and white label covers how delivery works behind your brand.
If you are close to the decision but not certain, a ninety-day pilot is the cheapest way to buy the information you are missing.
Questions people ask
Is it cheaper to outsource media buying or hire?
Outsourcing is cheaper until one person is busy on the work all month. Below that you are buying a fraction of several specialists instead of one full salary, tooling and the management time a hire needs.
Will my client know?
Not unless you tell them. Reporting carries your brand, the client talks to you, and the delivery team does not contact them. A partner who breaks that is not a partner.
What is the biggest risk in outsourcing?
Communication lag. Two layers between the client and whoever is in the account slows every decision. Agree response times in writing and give the delivery team read access to whatever records outcomes.
What if I only have one account to hand over?
That is the right number to start with. One account tells you how a partner works, what their reporting looks like and how fast they answer, at a scale where a bad fit costs you very little.
