In short: Self-serve suits small budgets in welcome categories. A flat-fee managed desk suits budgets past the fee floor, restricted categories and channels beyond the platforms, and an agency suits large multi-channel spend. Whatever you choose, the accounts stay in your name.
Key points
- Self-serve platform defaults are designed to maximise the platform's revenue; refuse them.
- Self-serve does not cover programmatic at scale, creator programmes, affiliate networks or cross-channel measurement.
- A flat-fee desk earns nothing extra by spending more, but below a certain budget the fee becomes too large a share.
- Percentage-based agencies earn more when you spend more, and agencies that front spend control account history.
- Ad accounts, conversion tracking, pixel history and analytics should always be in your company's name.
Every media platform now offers a self-serve interface. Anyone with a card can open an account, upload creative, choose an audience, and spend money within an hour. That raises a fair question: why pay anyone to do it for you?
The answer depends on three things: how much you spend, how much time you have, and whether the platforms will take your money at all.
Option one: run it yourself
Self-serve works when the budget is small, the product is in a category the platforms welcome, and someone on the team has the time to learn the interface and check the numbers daily.
The advantages are obvious. No fee. Full control. Direct access to the data. The disadvantages are less visible. The interface is designed by the platform to maximize the platform's revenue, and its defaults, broad audiences, automated placements, and optimization toward cheap events, serve that purpose. A self-serve buyer who accepts the defaults is spending efficiently for the platform.
Self-serve also stops at the platform's edge. Programmatic buying at any scale, creator programs, affiliate networks, and cross-channel measurement are not self-serve products. And if the category is restricted, the self-serve interface is where you will find that out, usually after building an account you cannot use.
Option two: a managed desk at a flat fee
A desk is a small team that runs the accounts on your behalf, in your name, for a fixed monthly fee per account. It sets inventory standards, manages verification, refreshes creative, optimizes toward the outcome you care about, and reports the numbers that matter: real cost per impression after verification, rejection rate, cost per outcome your own tracking confirms.
The fee does not change with spend, which means the desk earns nothing extra by spending more. That is the point. It also means there is a floor: below a certain monthly budget, the fee is a large share of the total and the arrangement stops making sense.
A desk is right when the budget is past the floor, the channels include programmatic or anything beyond the self-serve platforms, and you want the accounts, the data, and the history to stay yours.
Option three: an agency on a percentage
A traditional agency arrangement bundles planning, buying, creative, and reporting for a percentage of media spend, sometimes with the agency fronting the spend and billing you afterward.
It scales well for large budgets and complex, multi-channel plans. It also creates the incentive problem discussed elsewhere in this collection: the agency earns more when you spend more, and an agency that fronts spend controls the account history and platform relationships that should belong to you.
How to decide
Spending under a few thousand a month, in a welcome category, with time to learn: run it yourself, and refuse the defaults.
Spending past the floor, or in a category the platforms review, or needing programmatic and other channels beyond self-serve: a managed desk on a flat fee, with the accounts in your name.
Spending at a scale where buying power and multi-channel planning matter more than fee structure: an agency, with a contract that keeps the accounts yours and states the fee in dollars rather than as a percentage.
The one thing to keep in every case
Whoever runs the media, the ad accounts, the conversion tracking, the pixel history, and the analytics should be in your company's name. A partner who insists otherwise is asking to own the part of your business that is hardest to rebuild.

Common questions
Should I run my own ads or hire an agency?
Run it yourself if you spend under a few thousand a month in a welcome category and have time to learn. Use a flat-fee managed desk past that floor or in restricted categories, and an agency when buying power and multi-channel planning matter most.
What is a managed media desk?
A small team that runs ad accounts in your name for a fixed monthly fee per account, setting inventory standards, managing verification, refreshing creative and reporting verified costs.
What is wrong with agencies charging a percentage of ad spend?
The agency earns more when you spend more. An agency that fronts spend also controls the account history and platform relationships that should belong to you.
Who should own the ad accounts when working with an agency?
Your company. The ad accounts, conversion tracking, pixel history and analytics should be in your name, and a partner who insists otherwise is asking to own the hardest part of your business to rebuild.
