When a client signs up for your service, who is really responsible for making sure they stay? The salesperson who brought them in? The account manager who speaks to them every week? The team delivering the work, or the project manager supervising it?
The honest answer is all of them. Client retention is rarely one person’s job. It is shaped by everything the client experiences, from onboarding to delivery, communication, problem-solving and the value they keep receiving long after the contract is signed.
Working in Marketing Operations, I have learnt that managing a client relationship goes far beyond staying in touch. The business has to be organised enough to keep its promises, and the client has to feel supported throughout. Clients rarely care who carries out each task. What they care about is their overall experience of working with you.
That is where key account management comes in. In short, key account management is a structured way of managing your most important client relationships, so that you keep them, deliver consistently and grow the value of the relationship for both sides. It treats a major client as a long-term partner rather than a list of tasks, and it relies on the whole business working together, not just one account manager. The same habits, applied with a lighter touch, improve every client relationship you have.
How to decide which clients are key accounts
Not every client needs the same level of strategic attention, and very few businesses have the people to give it. In many businesses, a small number of clients bring in a large share of revenue, so it makes sense to know who they are.
A key account is usually a client that scores well on several of these: the revenue they bring, how profitable they are to serve, how much they could grow, how well they fit the kind of work you want more of, and how much influence they have, through referrals or the credibility of their name. Review your client list against these points at least once a year. The answer may surprise you. Your biggest client by revenue may not be your most profitable, and a mid-sized client may have more room to grow than anyone else.
Being a key account should never mean other clients are neglected. Every client deserves professional communication, reliable delivery and a good experience. A regular client who is well looked after today may become a key account tomorrow.
Client relationship management begins at onboarding
Winning a client is one thing. Managing the relationship after the business has been won is another, and onboarding sets the tone for everything that follows.
By the end of onboarding, the client should know what to expect, how you will work together, who is responsible for what, and how and when you will communicate. Just as important, your own team must understand exactly what was promised.
One of the most common problems in service businesses is the gap between what the sales team agreed and what the delivery team understands. When that happens, the client starts to experience delays, confusion and unmet expectations within weeks.
The fix is a proper handover. Before work begins, the salesperson should brief the account manager and delivery team on the client’s goals, the agreed scope, deadlines, budget and anything sensitive that came up in the sales conversations. Then hold a kick-off meeting with the client to confirm the scope, introduce the team, agree a single main contact on each side and set a rhythm for updates, such as a weekly progress note and a monthly report. Put the key points in writing, so there is one shared record of what was agreed.
Managing the relationship means managing the delivery
A client may have a dedicated account manager, but that person cannot deliver every service alone. A client working with a marketing agency, for example, may deal with the account manager, the content team, designers, the SEO team and other specialists. Each of them shapes the client’s experience.
The account manager is the main point of contact, but their real job is to keep everyone aligned: following up on deliverables, confirming progress, spotting gaps early and making sure each team knows what is expected. In my experience, client relationship management and operational efficiency are closely linked. When internal processes are disorganised, the client feels it. That is why no team should work in isolation. A business cannot consistently give clients a good experience if its own teams are not working together.
In Nigeria, much of this day-to-day contact happens in WhatsApp groups with clients. They are quick and convenient, but without some ground rules they can become noisy and confusing. Agree who on your side responds and how quickly, keep the group for updates and quick questions, and confirm important decisions, approvals and changes to scope by email, so there is a clear record.
Communicate delays before they become problems
Every business misses a deadline at some point. A task takes longer than expected, a team runs into a problem, or the client sends feedback later than planned.
The delay itself is not always the real issue. How it is communicated often matters more. Clients should never have to chase you for updates on work they are paying for. When a deadline is at risk, tell the client early, explain what happened in plain terms and give a revised timeline. If the delay comes from waiting on the client, say so politely and show how it affects the schedule.
Early, honest communication gives the client time to adjust their own plans. Silence does the opposite. It creates uncertainty and slowly damages trust. Managing a relationship well means being honest about progress, especially when things are not going to plan.
Managing conflicts and expectations
Not every client relationship will be smooth. There may be disagreements about deliverables, timelines, feedback, costs or the quality of work. Sometimes the client expects something that was never agreed. Sometimes the business genuinely fell short.
These moments need more than good communication. They need someone who will listen, understand the real concern and work towards a fair resolution. A good account manager can tell the difference between a request that can simply be accommodated, a change that needs extra time or budget, and a problem that needs to be escalated to senior management.
The most common source of friction is scope creep, which is when small extra requests slowly pile up until the work is far bigger than what was agreed. The answer is not to refuse every request. It is to acknowledge it, explain clearly whether it falls inside or outside the agreed scope, and if it falls outside, put the extra cost and timeline in writing for the client to approve before work starts.
The goal is not simply to avoid conflict. It is to resolve issues in a way that protects the relationship and is fair to both sides. A partnership does not mean agreeing to everything. It means being transparent, dependable and willing to find solutions.
Consistent attention is part of retention
Many businesses are very attentive when a client is new. Communication is frequent, replies are fast and the client gets plenty of attention. Over time, that attention fades. Updates only come when the client asks, and contact shrinks to deliverables, invoices and renewal discussions.
Clients notice. No client should feel that they only matter when a payment or renewal is due. Regular contact helps you understand how the client’s needs are changing, spot concerns early and find new ways to add value. Retention is not won by asking a client to stay at the end of the contract. It is earned through the experience they have every month before that.
It also helps to know the warning signs that a client may be drifting away. Replies take longer. Approvals and feedback slow down. Payments start arriving late. A new decision maker joins their team. Your contact stops sharing plans, or the client quietly reduces the scope of work. None of these means the relationship is lost, but each one is a signal to pick up the phone, ask how things are going and listen carefully.
It is also wise to build relationships with more than one person on the client’s side. If everything depends on a single contact and that person leaves or changes role, the relationship can disappear overnight. Get to know the decision maker, the day-to-day contact and, where possible, the people who use your work.
Are you managing accounts or building partnerships?
There is a real difference between managing an account and building a partnership. Managing an account focuses on the immediate tasks: answering requests, completing deliverables, sending invoices and keeping in touch. Building a partnership goes further. It means understanding the client’s business priorities, the pressures they face and where they want to be next year, and then thinking about how your work can help them get there.
Two simple tools make this practical for key accounts. The first is an account plan, a one-page document for each key client that records their goals for the year, the people involved on their side and what each cares about, the risks to the relationship and the opportunities to do more for them. The second is a quarterly business review, a meeting every three months where you step back from day-to-day tasks, look at results together, discuss what is changing in their business and agree priorities for the next quarter. Clients rarely forget a supplier who takes the time to understand their business this way.
The aim is a strong foundation of relationship management for every client, with this deeper, more strategic approach reserved for the accounts with the most potential.
The role of Marketing Operations
Marketing Operations is the function that makes all of this work in practice. It builds the systems, processes and coordination that keep client information in one place, track deliverables, make responsibilities clear and help teams work together.
A well-run business should be able to see, at any time, the status of a client’s deliverables, outstanding tasks, upcoming deadlines, past concerns and recent conversations, without relying on one person’s memory. A simple client management system, or even a well-organised shared tracker, makes this possible. When that information is properly managed, the business makes better decisions and responds faster to what clients need.
Marketing Operations also connects the people who speak to clients with the people who do the work. That matters, because a client relationship is not built through communication alone. It is built through the organisation’s ability to deliver what it says. The account manager may lead the relationship, but the whole business has to support it.
How to measure key account management
What gets measured gets managed, so track a few simple numbers for your key accounts. Look at how many clients renew or continue working with you each year, and how revenue from each key account changes over time. Track how often deliverables are completed on time. Ask clients for feedback regularly, through a short survey or a direct conversation at each quarterly review. Watch the warning signs described above, such as late payments or slower approvals. Over time, these numbers show you which relationships are getting stronger, which need attention and whether your approach is working.
Building client relationships that last
Key account management should not be seen only as a way of keeping important clients happy. It is a way of running the business that connects understanding the client, coordinating the team, delivering the work and growing together over time.
From onboarding to renewal, every interaction shapes how a client sees you: how you communicate, how you manage deliverables, how you handle problems and how consistently you add value.
In my view, the real test of client relationship management is not how well a business wins a client. It is how well it takes responsibility for the relationship after the client has been won. Clients may come to a business because of its promise, but whether they stay depends on how well that promise is kept.
So, is your business simply managing accounts, or building partnerships that clients have every reason to keep?
At Evaluate Media, this is how we approach every client relationship, with a dedicated point of contact, coordinated teams across content, design, digital marketing and PR, and regular reviews of progress against each client’s goals.

How do you identify a key account?
Look at the revenue a client brings, how profitable they are to serve, how much they could grow, how well they fit the work you want more of and how much influence they have through referrals or reputation. Clients who score well on several of these are your key accounts.
Who is responsible for managing a client relationship?
The account manager is usually the main point of contact, but the relationship is a shared responsibility. Sales, delivery, operations and management all shape the client’s experience.
How can a business improve client retention?
Set clear expectations at onboarding, hand over properly from sales to delivery, deliver consistently, tell clients about delays early, handle disagreements fairly and stay in regular contact, not only when an invoice or renewal is due.
What are the warning signs that a client may leave?
Slower replies, delayed approvals, late payments, a new decision maker, less information sharing and a reduced scope of work are common signs. Each is a cue to start an honest conversation with the client.
