CAC, customers don’t come for free (even when your product is amazing)

Making money costs money, its just investing in your business, instead of the stock market.

There is a particular kind of business problem that looks like a marketing problem from the outside, but is actually a mindset problem on the inside.

A few years ago, I worked with a client selling a high-value product. Their lowest-cost option was around £15,000, but many of the sales came in just shy of £20,000, with some reaching as high as £30,000.

This was not a small-ticket item or an impulse buy. It was a considered purchase, aimed at a specific type of customer with a specific need, in a specific type of home.

The gross profit on the lower-value sales was around £6,000, so there was room to build a proper acquisition model.

So after some simple rebranding and positioning work  to make sure the company presented itself in the right way we set about answering the question we looked at the market and how best to get more customers for them. A simple question…

“How do we find more of the right people, get in front of them, and give them enough confidence to make an enquiry?”

We did what should always be done before throwing money at marketing and asked some fundamentally simple questions.

Where were the likely buyers? What kind of homes did they live in? Which areas had the right demographics? Where did the product make practical and financial sense? Where could we avoid wasting effort?

This was not a “spray and pray” concept. It was targeted, practical, and grounded in the reality of who was actually likely to buy. Using targeted leaflet drops into carefully selected areas, offering a free survey and quote.

The cost to print and deliver the leaflets was around £160. When an enquiry came in, the cost of carrying out the survey and preparing the proposal was around £100. We automated as much of the proposal process as possible to keep the cost down, but the site visit still mattered. At this price point, people needed to feel advised, not processed.

Roughly one in five enquiries converted.

So, assuming five enquiries were needed to create one sale, the acquisition cost looked like this:

Five surveys at £100 each = £500Targeted leaflet print and delivery = £160Total customer acquisition cost = £660

On the lowest-value product, at £15,000, that CAC was around 4.4% of the sale value.

On a more typical sale just shy of £20,000, it was closer to 3.3%.

On the higher-end sales, around £30,000, it was just 2.2%.

And that was just taking into consideration those that did not convert straight away, and let’s face it when you are spending the amount of money that could buy a new “to you” car people can often be slow burners when it comes to pulling the trigger on a purchase.

So the business was not being asked to gamble wildly on marketing. It was being asked to invest somewhere between roughly 2% and 4.5% of the sale value to acquire a customer. Sure it impacted their overall margin but in the scheme of things they had a healthy margin in the first place to work with so it should not really have been seen as a major issue.

But the client could not see it. They became fixated on the free surveys.

Anytime someone did not proceed, they saw the survey as a loss. They saw the visit, the time, the proposal, the cost, and the inconvenience. They could not get past the feeling that they had given something away for nothing.

But that is not how customer acquisition works. The survey that does not convert is not a random loss.

It is part of the cost of finding the one that does.

That is what CAC — Customer Acquisition Cost — actually means.

It is not the cost of the failed quote. It is not the cost of the person who says no. It is not the cost of the visit that does not turn into an order.

It is the total cost required to acquire a paying customer.

And in this case, the business was spending around £660 to win sales that were typically worth close to £20,000, sometimes much more.

Even on the lowest-value product, the numbers worked. But the client could not get comfortable with the process. So they changed the offer.

No more free surveys.

Customers would now have to pay for the survey upfront, with the cost deducted from the purchase price if they went ahead. On paper, that sounds reasonable. Sensible, even. It filters out time-wasters. It protects the business. It makes sure customers that come to the table have some skin in the game.

Except customers do not always behave the way a spreadsheet wants them to. Especially not at the early stage of a considered purchase.

The free survey was not just an operational step. It was part of the sales mechanism. It lowered the barrier. It gave people a reason to enquire. It allowed the business to start a conversation before the customer had fully made up their mind.

The moment the survey had a price attached to it, enquiries dried up. I explained why. But because on paper the CAC number “seems high to me” The client was willing to lose the customer journey to avoid spending roughly 3.3% of a typical sale.

And this is where the lesson bites.

During the short six-month period where the business ran targeted leaflet drops and offered free surveys, they made more sales than they had in the previous two years. More sales in six months than in the previous two years.

The evidence was there. In a short period it was showing results. Sales were increasing. But the client presented a refusal to accept that acquiring customers costs money.

Eventually, the phone call came.

“It’s not working. We need to stop with the marketing.”

But the marketing was not the thing that had stopped working. The business had stopped doing the thing that made the marketing work. There is a huge difference.

A few months later, the business was gone, because the market disappeared. Not because the product had no demand & certainly not because the numbers were impossible.

It disappeared because the owner could not reconcile the idea that spending money to acquire customers was part of doing business.

The old adage applies perfectly:

0% of anything is still 0.

Keeping 100% of your profit sounds great until there are no sales to take profit from.

And yes, after stopping the activity that had generated the best results they had seen in years, they spent a few months making Canva posts. Then they evaporated. There is nothing wrong with Canva. There is nothing wrong with social media. There is nothing wrong with trying to create awareness cheaply. But cheap is not the same as effective.

And free marketing is rarely free. It usually costs time, consistency, skill, attention, strategy, content and patience. If none of those things are properly invested, it is just noise with a logo on it.

The uncomfortable truth is this, a business that cannot accept CAC cannot scale. It will always see marketing as a gamble, sales activity as a burden, and every non-converting lead as a personal insult. But customer acquisition is not wasted money just because every enquiry does not buy. It just part of the machine.

If it costs £660 to generate a sale worth somewhere between £15,000 and £30,000, you do not stop the machine because four people said no. You can refine the process, analyse the results to try and bring CAC down. You refine the process. You look capitalise on previous sales with referrals, repeat business and lifetime value. You can even build the cost into your profits if the product can bear the burden.

What you do not do is remove the very thing that made people enquire in the first place.

That is self-sabotage wearing a hi-vis jacket and pretending to be financial discipline.

CAC is not always comfortable. In some businesses, it feels painful because the cost happens before the reward.

You pay for the leaflet before the phone rings. You pay for the survey before the customer says yes.  You absorb the no before you get to the yes.

Because the businesses that grow are not always the ones with the best product, the best logo, or the prettiest Instagram grid. They are often the ones that understand a very simple equation:

Customers cost money to acquire. Profit comes after that, not before it.
