Do You Actually Know What a Customer Costs You?

And we ask them one question that nearly always stops the conversation dead.

“How much are you willing to spend to get one new customer?”

Most can’t answer it.

Not because they’re not smart. They run the whole operation in their head, every day, and it works. But that one number, the price of a customer, has never been written down anywhere. So the question gets a shrug. Or a guess. Or “I dunno, whatever works?”

Here’s the thing. You’re already paying to get customers. You just haven’t added it up.

You’re already spending it

Think about everything that has to happen before someone hands you a job.

You might run Google Ads. That’s money out the door whether the phone rings or not.

You pay for your website to sit there and be found. You’ve maybe paid an agency, or paid for listings, or chucked some money at Facebook.

You spend Saturday mornings driving out to quote jobs you don’t win. That’s fuel, and it’s your time, which is the one thing you can’t make more of.

You give your best customers a discount to send their mates your way.

Every one of those is a cost of getting a customer. Add them all up over a month, divide by how many new customers you actually won, and you’ve got a number.

That number is what a customer costs you.

Let’s do the maths

Say you’re a builder. Last month you spent:

That’s $1,200 spent on getting work.

That month, you won four new jobs.

$1,200 divided by 4 is $300.

So right now, it costs you $300 to win one new customer. That’s your number. We call it your cost per customer, or your acquisition cost if you want the fancy version, but the plain word is fine.

Now. Is $300 good or bad?

You can’t answer that yet. And this is where most people come unstuck.

$300 means nothing on its own

A $300 cost to win a customer is brilliant if that customer is worth $5,000 to you.

It’s a disaster if that customer is worth $250.

The number on its own tells you nothing. It only means something when you put it next to what a customer is actually worth to your business. Not the price of the job. What you keep after the job is done and paid for.

That’s the part nearly everyone skips. They look at the job price, feel good about it, and never ask what’s left over once the materials, the labour, the fuel, the tools, the insurance, and the GST have all been paid.

We’ll get into that properly in another piece, because it’s the bit that quietly sinks good businesses. For now, just sit with the gap.

You probably know roughly what a job sells for.

You probably don’t know what it costs you to win one.

And without both numbers, every marketing decision you make is a guess.

Why the guessing is dangerous

When you don’t know what a customer costs you, a few things happen, and none of them are good.

You can’t tell which marketing is working. The ads might be carrying you. The ads might be bleeding you dry. You genuinely cannot say, so you keep paying for both the good and the bad.

You can’t say yes to growth with any confidence. Someone offers you a way to get more customers, and you’ve got no way of knowing if it’s worth it, so you either jump in on a gut feel or freeze and do nothing.

And worst of all, you stay busy without getting ahead. The work comes in, the days are full, the bank account just sort of sits there. We see this one constantly. Booked solid, and somehow no better off.

The good news

You don’t need a finance degree to fix this. You don’t need fancy software. You need one afternoon and a willingness to look.

Pull your last three months. Add up everything you spent on getting work, fuel and quoting time included. Count the new customers you won. Divide.

That’s your number. Write it down. It’s probably the single most useful number in your whole business, and most of your competitors don’t know theirs either.

Once you can see what a customer costs you, you can start to manage it. Push it down. Spend more where it’s working and less where it isn’t. Decide, on purpose, what you’re willing to pay.

But none of that happens until you stop shrugging at the question.

So we’ll ask it again, and this time we’d love you to have an answer.
