How do you keep a marketing client long term?

The way to keep a marketing client long term is to understand how their business makes money, and then attach yourself to that cash flow. Ask where they make money, how they lose money and what their biggest cost is. Then find a way to be useful inside that process, beyond the marketing you already do. As soon as you adjoin yourself to the cash flow, you will always have recurring clients.

This came up on a team call, when we were talking about how you become first with a client. My answer was much simpler than most people expect.

Why should a marketer care about how the client makes money?

Whenever you market a business, the most important thing is to understand how it makes money. That is what tells you how to market it.

Most of what you study about marketing comes down to very simple concepts like this one. The studying and the bookish knowledge just build layers around it. The core underneath stays the same.

In any business, everything is linked to cash flow. The whole ecosystem is linked to it. That is the right way to look at any business you work with.

So the first job is to really understand the business. When you do, you can talk to the owner to the point. Where do you make money? How do you lose money? Which is your biggest cost? Those might not sound like marketing questions. But they tell you where the business actually lives, and that is where your work should connect.

Why is marketing on its own not enough to keep a client?

If you only do marketing, you are not linked to sales. That makes you very expendable. The work you made earlier can be reused without you, and the value is not tangible. A client can say tomorrow that they do not know how much difference social media made to their sales.

The ground is also shifting. Before, creativity was the key. Founders could not do their own marketing, so they needed you. That gap has become very small now. People do not even send you questions. They send you a brief straight from GPT saying what they want. Soon even that step may go.

So how do we upskill ourselves? Creativity today is a combination of marketing, operations, automations, everything. To stay valuable, you have to create long term interdependent relationships.

What does becoming part of the cash flow look like in practice?

Whenever you want to link a client to permanence, there are two ways. Either you become a key cog in their sales process, something they rely on to make money. Or you become the cause of it.

For some clients, we are the cause, because we bring the leads. For others, we become the cog, because we build something that sits inside how they sell.

One client wanted a sales deck for their bespoke offering, and they needed a new one every time. So I built a tool that makes the deck on the fly. You enter the brand and its colours, and it creates a branded deck automatically. It is not as good as one our designers would make, but for the less important pitches, why not?

I did not stop there. I also built them a sales kit for their salespeople, all on a simple website. Three rules before you reach out. A prospecting playbook. How to find people on LinkedIn Sales Navigator. Copy and paste messages. How to follow up. How to handle a no. All their products, the entire range they are trying to sell, in one place. Then a printable brochure of the same thing.

Now we are part of their sales process. You keep creating useful assets, and that is what makes the relationship last.

It does not always have to be sales. For a restaurant, what we made is linked to operations: loyalty cards. And if we build a tool that a client's sales run through, we become much more valuable to them, because the business relies on it.

Even prototypes help. Going from prototype to final product takes much longer, but a prototype shows the client how far your brain goes and how fast you are thinking.

When should you bring these extra tools to a client?

Do not give everything together. You have to judge when you need it.

If it has been a long time and the work has become routine, the same thing every month, that is a good moment to bring something new.

For example, imagine a tool where you take a photo of a fabric and a photo of a room, and it shows how the curtains or the bed will look. An idea like that is most valuable when it arrives at the right time.

So what is the simple rule?

Marketing is an ongoing activity. Marketing is a relationship. And like any relationship, it comes down to one thing: how do you make yourself useful to them?

So when my team asks how to keep a client long term, this is what I tell them. Understand the business first. Find where the money comes in, where it goes out and what costs the most. Then make yourself useful inside that process, either as the cause of their sales or as a cog they rely on. Do that, and the recurring work follows. That's finished. It really is that simple.
