Every agency pitch is a story of promises. Senior talent. Strategic insight. Category expertise. Proven results. The story is compelling, the contract is signed, and, ideally, Procurement was involved along the way.
The pitch process receives enormous time and resource. The move from pitch to delivery, and the ongoing accountability for what was promised, gets far less attention than it deserves. Other priorities take over, a full evaluation can’t be justified across the entire roster, and the team loses sight of the detail. That loss of visibility has consequences.
THE PITCH-DELIVERY GAP
There is a structural reason why what agencies sell and what they deliver so often differ. In many agencies, the senior person who wins the account is not the person who services it. The team that impressed you in the room moves on to the next pitch, and your account passes to an execution team you have never met, and who may never have appeared on the staffing plan.
The economics explain it. Senior time is an agency’s scarcest resource, and it earns the most when it goes toward winning new business rather than servicing existing accounts. The result is a gap between the people you assessed and trusted and the people who show up on your account every day.
Most of the familiar complaints about agency relationships are that same gap, felt in different places: work that drifts from the pitch promise, senior attention that gets harder to access, feedback that comes back slightly off, and prices that reflect senior talent while delivery feels junior.
THE EVALUATION PROBLEM
The gap persists not because Marketing Procurement teams are naive, but because most brands lack the data and the process to detect it systematically. Marketing is often content as long as the work is producing results, and strong results can mask a change in who is doing the work. Without a structured way to evaluate what was promised against what is delivered, it becomes impossible to demonstrate the value an agency is providing, or the value it isn’t.
Marketing and Procurement are also looking at very different metrics, and that difference can make managing the contract period an uphill battle for Procurement.
WHAT TO TRACK
Effective post-pitch accountability means tracking three dimensions.
Staffing plan compliance is the most immediate and the most frequently neglected. Every agency contract should specify the roles, seniority levels, and time allocations of the team on the account. Procurement can then review whether the team doing the work matches the team that was pitched. If the senior creative director who featured prominently in the pitch has quietly been replaced by a mid-weight team, that is a material change to what was contracted, and it should be addressed as one. The same applies to AI: if the balance between human time and automation shifts during the term, that shift should be visible and explained. Where fees are set at asset level, the check goes a step further. Was the work priced as a master actually originated by the promised senior team, or was it an adaptation delivered at master rates?
Delivery performance should be tracked against the scope of work agreed at contract stage: what was briefed, what was delivered, when, and how many rounds of amends were needed. Scope management is the fastest route to a better agency relationship. Without it, agencies build contingency into their pricing, and the brand ends up paying for it. The reverse is also true, without tracking data, the brand has no basis for challenging delivery that falls short of what was agreed.
Commercial results are often the hardest to track, because the link between agency output and business outcome is rarely linear. But Marketing Procurement can still build a framework for assessing whether the work is producing the results outlined in the pitch. The starting point is agreeing those measures with Marketing before the contract is signed.
BUILDING THE ACCOUNTABILITY FRAMEWORK
The most effective agency evaluation frameworks share characteristics:
- They are agreed before the contract is signed, not introduced once the relationship has started.
- They are reviewed regularly and consistently, with input from both Marketing and Procurement.
- They define what happens when performance falls below agreed thresholds.
- They are underpinned by data.
Many brands loosely track agency performance without any real process for acting on it. The data sits in a spreadsheet, concerns are noted, but nothing changes. The brand is not comparing performance across its entire agency roster, so the exercise becomes record-keeping rather than a way to separate high-performing agencies from those falling short.
Used well, agency performance data is the basis for a constructive conversation, and it gives opportunity to course-correct before the relationship reaches breakdown. We often see brands willing to stay with an underperforming agency if it is prepared to address the issues. But that conversation is only possible with a robust evaluation framework behind it, one that supplies the right insight and intelligence.
MARKETING PROCUREMENT’S ROLE
When it comes to post-pitch accountability, Marketing Procurement’s role is not to police agencies. It is to create the conditions in which they can be held to account fairly, and to make sure the brand has the data to make informed decisions about its agency relationships. That means building the infrastructure before the relationship starts, maintaining it consistently through the contract period, and using independent data to support every stage.
The pitch shows what an agency says it can do. The framework shows whether it does.
