Why agency selection defeats normal procurement
Agencies sell judgement and taste, which resist specification: you cannot write an RFP line for the idea that changes the brand's trajectory. So selection collapses onto chemistry and the pitch, both of which the agency controls completely. The speculative campaign that won the room was produced by a pitch team at a loss, as a marketing cost; recovering that cost is built into the fees and staffing of the account you are about to sign. That economics does not make agencies villains, but it does make the buyer responsible for negotiating the delivery reality rather than the pitch performance, because only one of them appears in the contract.
The recurring gaps between promise and account
- The named creative and strategy leads from the pitch are allocated at a fraction of their pitch involvement, and the contract is silent on it.
- The retainer scope was drafted broadly to close the deal, and within two quarters the agency is flagging out-of-scope fees for work you assumed was covered, or absorbing it and reducing seniority on the account to protect margin.
- Media performance is reported by the agency that bought the media, against benchmarks the agency selected, with attribution assumptions the agency chose. The homework is marked by its author.
- Principal-based buying, rebates and inventory arrangements can mean the agency earns from the media it recommends: an incentive that shapes recommendations towards spend, and one many contracts never require to be disclosed.
- Ad accounts, audiences, pixels and historical performance data sit in agency-controlled structures, and their portability is discovered only during the breakup.
What to ask before the chemistry decides for you
Ask which named individuals will spend a defined number of hours per month on your account, written into the agreement with substitution rights. Ask how the agency makes money on an account like yours (fees, media commission, production mark-up, principal inventory) and treat reluctance to answer as the answer. Ask for two former clients, not current ones, and specifically ask them how the relationship ended and what the transition out was like. Ask what happens to your data, accounts and creative files on exit, and get the answer into the contract while the agency still wants something from you. And ask internally: is the brief good enough to judge an agency against, or are you hiring energy to compensate for a strategy the organisation has not actually agreed?
Pressure-test the measurement before you fund the media
The single highest-value clause in an agency relationship is independent measurement. Before committing meaningful media spend, define with the agency, in writing, what success is, over what period, measured by whom, with what attribution logic, and what happens if the numbers disappoint. Insist on direct admin access to every platform account running your money, so the raw numbers are yours to inspect rather than arriving pre-narrated in a monthly deck. Agencies that welcome this arrangement are usually the ones whose work survives it. The ones that resist are telling you, in advance, how the difficult conversation in month nine will go.
What people who have hired and fired agencies know
Marketing leaders who have run several agency relationships to their conclusions offer a consistent diagnosis: most failed relationships were mis-briefed, not mis-chosen. The organisation hired a brand agency to fix a distribution problem, or a performance shop to solve a positioning question, because the pitch was impressive and the internal diagnosis was thin. The second consistent finding concerns retainers: they reward the agency for being needed rather than for being effective, and relationships structured around defined projects with defined outcomes age better than open-ended retainers reviewed annually. Independent perspectives before signature tend to fix the brief first and the shortlist second, in that order, because a sharp brief exposes which agency is actually right in a way no pitch can.
