Managing Agency Partners Without Losing Control of the Work

Managing agency partners well is one of the most underrated skills in marketing leadership. Get it right and you multiply your team’s output without multiplying headcount. Get it wrong and you spend more time managing the relationship than you do managing the work, and the results suffer accordingly.

The difference between a productive agency relationship and a draining one usually comes down to three things: clarity of expectations before the work starts, honest communication when things go sideways, and a client-side owner who understands enough about the craft to ask the right questions. Most breakdowns happen because at least one of those three is missing.

Why Most Agency Relationships Underperform

I have been on both sides of this equation. I spent years running agencies, managing client relationships, and watching good briefs turn into disappointing campaigns and mediocre briefs somehow produce brilliant work. The pattern I kept seeing was this: clients who struggled with agency partners almost always had an internal process problem, not an agency quality problem.

That is a difficult thing to say to a client who is frustrated with their agency. But it is usually true. When the brief is unclear, when sign-off takes three weeks, when feedback arrives in six separate emails from four different stakeholders with contradictory opinions, the agency cannot do its best work. The output reflects the input, and the input is controlled by the client.

This does not let agencies off the hook. There are agencies that overpromise in pitches and underdeliver in practice, that rotate junior staff onto accounts without telling the client, that produce work that is technically on-brief but commercially useless. Those problems are real and I will come to them. But if you are reading this because you are frustrated with an agency partner, start by auditing your own side of the relationship before drawing conclusions about theirs.

If you want a broader view of what healthy agency operations look like from the inside, the Agency Growth and Sales hub covers the commercial and operational realities that shape how agencies think and prioritise, which is useful context when you are sitting on the client side of the table.

How to Brief an Agency So the Work Actually Lands

A brief is not a document. It is a conversation with a document attached. The document captures the output of the conversation, but the conversation is where the real alignment happens. I have seen clients hand over a ten-page brief, decline a briefing meeting, and then express surprise six weeks later that the creative work missed the mark entirely.

A good brief answers five questions clearly: What is the business problem we are trying to solve? Who are we talking to and what do we know about them? What do we want them to think, feel, or do differently after seeing this work? What does success look like in measurable terms? And what constraints, commercial, legal, brand, or timing, does the agency need to know about before they start?

That last one matters more than most clients realise. Early in my agency career, we developed a Christmas campaign for a major telecoms client that we were genuinely proud of. The creative was strong, the strategy was sound, and the client was excited. Then, days before it was due to go live, a music licensing issue surfaced that none of us had anticipated, despite having a music industry consultant involved from the start. The campaign had to be scrapped. We rebuilt from scratch, got client approval, and delivered on time, but the pressure was extraordinary and entirely avoidable. The constraint existed. It just was not surfaced early enough. That experience changed how I run briefings permanently.

The briefing meeting should include whoever holds the relevant constraints on the client side: legal, compliance, brand, procurement. Not to slow things down, but to surface blockers before the agency has invested weeks of creative thinking in a direction that cannot be approved.

Setting Up the Governance Without Strangling the Work

Governance in agency relationships is one of those things that sounds bureaucratic but is actually a creative enabler. When the process is clear, the agency can spend its energy on the work rather than on managing uncertainty about what happens next.

The basics are simple but frequently skipped. Agree on a single point of contact on each side. Agree on how feedback will be consolidated, not cascaded through multiple channels. Agree on what constitutes a change to scope and how that will be handled commercially. Agree on the approval process and who has final sign-off authority. Write it down. Review it at the start of each major project.

The most common governance failure I see is the multi-stakeholder feedback problem. An agency submits creative work. The client-side contact shares it internally for input. Five people respond with conflicting notes. The contact tries to synthesise them and produces feedback that is internally contradictory. The agency tries to address all of it and produces work that satisfies no one. This cycle repeats until everyone is exhausted and the deadline is at risk.

The fix is not complicated. One person consolidates feedback before it goes to the agency. That person has the authority to make decisions, not just collect opinions. If there is genuine disagreement internally, it gets resolved before the agency sees it, not after. This is a discipline issue, not a process issue, and it requires someone senior enough to hold the line.

Weekly status calls are fine if they have a clear agenda and a decision-making purpose. If they are purely informational, consider whether an async update would serve the same function without consuming an hour of both teams’ time. Not every touchpoint needs to be a meeting. But when something is going wrong, meet in person or on video. Email and Slack are not adequate channels for difficult conversations.

How to Handle Scope Creep Before It Becomes a Problem

Scope creep is the slow erosion of a commercial relationship. It usually starts with something small, a minor additional deliverable, a quick amend that turns into a significant revision, a request that falls just outside the original brief. Each individual instance feels reasonable. The cumulative effect is that the agency is doing materially more work than it is being paid for, which means it either absorbs the loss or quietly reduces the quality of what it delivers to compensate.

Neither outcome is good for the client. An agency absorbing losses on your account is an agency that will eventually deprioritise your work or lose the team members who were doing it. An agency quietly cutting corners to protect its margin is producing work below what you are entitled to expect.

The solution is to treat scope as a commercial document, not a rough guide. When a request falls outside the agreed scope, the agency should flag it and the client should expect to. If the additional work is genuinely small, agree on how it will be handled. If it is significant, process a change order. This is not adversarial. It is how professional service relationships stay healthy over time.

From the agency side, I always encouraged account managers to flag scope changes early and in writing, not to be difficult, but because letting it accumulate and then raising it as a large issue at invoice time is far more damaging to the relationship than addressing it as it arises. The same principle applies from the client side. If you are asking for something extra, acknowledge it and ask how it should be handled.

Evaluating Agency Performance Without Relying on Vanity Metrics

How you measure agency performance shapes how the agency behaves. If you measure on impressions and engagement, you will get work optimised for impressions and engagement, regardless of whether those metrics connect to business outcomes. If you measure on revenue impact, pipeline contribution, or cost per acquisition, you will get work oriented toward commercial results.

This sounds obvious but it is frequently ignored in practice. Many client-agency relationships still operate on activity metrics, reports delivered, posts published, campaigns launched, because those are easy to count. The harder work is agreeing upfront on what commercial outcome the agency’s work is supposed to influence, and then building a measurement framework that connects their activity to that outcome.

I spent time judging the Effie Awards, which evaluate marketing effectiveness rather than creative craft. The entries that stood out were not necessarily the most polished or the most innovative. They were the ones where the agency and client had agreed on a specific business problem, built a strategy to address it, and could demonstrate a clear line between the work and the outcome. That clarity of purpose is rare, but it is achievable, and it starts with how you set up the relationship, not how you evaluate it at the end.

A practical approach: set three to five outcome metrics at the start of each engagement or campaign. Make them specific. Make them time-bound. Review them at the midpoint, not just at the end, so there is time to course-correct if the work is not tracking toward the right result. Do not wait for a campaign to finish before having the honest conversation about whether it is working.

For agencies building out their own service offering and trying to understand what clients actually need, Semrush’s breakdown of digital marketing agency services is a useful reference point for understanding how clients categorise and evaluate the work they commission.

When to Push Back on Your Agency and When to Trust Them

One of the most common mistakes I see from clients is hiring an agency for their expertise and then systematically overriding their recommendations. This is not always wrong. Agencies can be wrong. But if you find yourself routinely rejecting strategic advice from a team you are paying specifically for their strategic thinking, something has broken down, either in the quality of the agency’s work or in your willingness to let them do their job.

Push back when the recommendation does not connect to the business problem. Push back when the rationale is vague or trend-driven rather than grounded in evidence. Push back when the agency is recommending something that conflicts with what you know about your customers or your commercial constraints. These are legitimate reasons to challenge the work.

Do not push back simply because the creative work makes you uncomfortable or because it is different from what you expected. Discomfort is sometimes a signal that the agency has found something genuinely differentiated. The question to ask is not “do I like this?” but “will this work for the audience and the objective?” Those are different questions and they require different answers.

I remember walking into a brainstorm early in my career, handed a whiteboard pen by a founder who had to leave for a client meeting, and expected to lead a room of people I had barely met. The internal voice said this was going to be difficult. It was. But the experience taught me something useful: the people in that room were not looking for someone to perform confidence. They were looking for someone to create the conditions for good thinking. That is what good clients do for their agencies too. They do not need to be the smartest person in the room. They need to create the conditions for the agency to do its best work.

Managing Multiple Agency Partners Without Creating Chaos

Many marketing teams work with multiple agency partners simultaneously: a creative agency, a media agency, an SEO specialist, a social media partner, perhaps a PR firm. Each has its own account team, its own process, and its own view of what success looks like. Coordinating across all of them without creating duplication, conflict, or gaps is a genuine operational challenge.

The most common failure mode is siloed agency relationships. Each agency does its work, reports to its own contact, and has no visibility into what the others are doing. The client-side team is the only point of integration, and if that team is stretched, integration does not happen. The creative agency produces work that the media agency has not been briefed on. The SEO agency optimises for keywords that conflict with the messaging the creative agency has developed. The social team posts content that undermines a campaign the PR team has spent weeks building.

The fix requires a deliberate integration layer. This does not have to mean a monthly all-hands with every agency partner in the room, though that can be useful quarterly. It means someone on the client side owns the overall picture and actively shares relevant information across agency partners. It means briefs reference what other agencies are working on where it is relevant. It means the agencies know each other exists and understand enough about each other’s remit to flag potential conflicts.

Some organisations appoint a lead agency to coordinate across the roster. This can work well if the lead agency has the commercial incentive and the operational capability to do it properly. It can work badly if the lead agency uses the position to protect its own turf or if the other agencies resent the hierarchy. There is no universally correct model. The right structure depends on the size of your marketing operation, the complexity of your channel mix, and the maturity of your agency relationships.

If you are building out your agency roster and want to understand what a well-structured agency looks like from the inside, Buffer’s guide to starting a social media marketing agency gives a useful perspective on how specialist agencies think about their own positioning and service delivery.

When to End an Agency Relationship

Ending an agency relationship is one of the more uncomfortable decisions in marketing leadership, partly because it involves people, partly because it means admitting that the investment has not delivered what was hoped, and partly because the process of finding and onboarding a new agency is genuinely time-consuming.

But staying in a relationship that is not working because change feels hard is a worse decision than making the change. The question is how to know when you have reached that point.

There are a few clear signals. The work is consistently below the standard agreed at the start of the relationship and feedback cycles have not improved it. The agency has rotated the team on your account without consultation and the replacement team does not have the same capability. The agency is consistently over-promising and under-delivering on timelines and quality. Trust has broken down to the point where every deliverable requires adversarial review rather than collaborative refinement.

Before pulling the trigger, have one direct conversation. Not a passive-aggressive email, not a pointed comment in a status call, but a direct conversation with the agency’s senior leadership that names the problem clearly and gives them a defined period to address it. Most agencies, when they understand that the relationship is genuinely at risk, will mobilise quickly. If they do not, or if the improvement does not materialise, you have your answer.

When you do make the change, manage the transition properly. Give reasonable notice. Ensure knowledge transfer, particularly for anything involving technical access, data, or ongoing campaigns. Treat the outgoing agency professionally. The marketing world is smaller than it appears and the people you work with today will be in different seats in three years.
