Stop Refilling the Bucket. Fix the Hole.

I have sat on both sides of this table. Client side, watching a marketing budget get poured into the top of the funnel every quarter. Agency side, being paid to keep pouring. Here is the thing neither side wants to say out loud when the market gets tight.

Most Australian businesses are trying to grow by chasing strangers while quietly bleeding out the customers they already paid to win.

That is the argument. When acquisition gets expensive and households pull back, you do not grow by refilling the top of the funnel faster. You grow by stopping the leak at the bottom. Push back on that if you want. I have watched too many P&Ls to soften it.

The money is getting tighter and the customer is getting choosier. That is not a mood. That is in the numbers.

Deloitte Access Economics has discretionary spending growth slowing from 2.5% in the year to December 2025 to 0.7% in the year to December 2026. Retail turnover growth drops to 1.8% next year, down from 2.3% this year. The tap is closing. (Deloitte)

The customer already knows it too. Power Retail found 66% of Australians expect cost of living to get worse. When they cut, they cut the fun stuff first. Eating out 72%, takeaway 61%, shopping and retail 57%. (Power Retail)

So your pool of warm audience is shrinking and your cost to reach a stranger keeps climbing. If your only plan is spend harder to acquire, you are spending more to convince a more reluctant person to try you for the first time. That is not a strategy. That is a hope.

Acquiring a new customer costs roughly 5 to 25 times more than keeping an existing one, and a 5% lift in retention can raise profit anywhere from 25% to 95%. Yet repeat customers, who can carry close to 44% of revenue from around a fifth of the customer base, are the group most businesses under-invest in.

New Rebellion scores Australian businesses across six dimensions. I will not throw dataset counts at you because that is not the point. The point is the pattern, and the pattern is boringly consistent.

Retention is the weakest dimension. Not in one industry. Across the board. Businesses will build a decent acquisition engine, put a reasonable amount of thought into brand, get their tracking half sorted. Then the moment a customer has actually bought something, the machine goes quiet. No follow up. No reason to come back. Nothing.

Here is what makes retention the weakest dimension. It is nobody's job. Acquisition has an owner, a budget line and a dashboard everyone stares at. Retention sits between marketing, sales and whoever happens to run the email account. So it gets neglected. Not because people are lazy. Because there is no seat at the table with retention written on it.

I will be honest about my side of the fence, because it matters. Agencies are mostly paid to acquire. The pitch is new customers, new campaigns, new reach. That is what wins the account and that is what fills the invoice. Retention is quiet, unglamorous work that does not need a big media budget, so almost nobody leads with it.

That is the uncomfortable part. The people you pay for marketing advice are structurally pointed at the expensive half of the problem. Not out of malice. Out of incentive. A lot of it is just self interest dressed up as strategy. If your agency has never once walked in and told you to spend less on acquisition and more on keeping the customers you have, ask yourself why.

The customer journey is a dating cycle. First there is visibility, they see you exist. Then engagement, they start poking around, reading, following. Then you go out, the first purchase. Then, if you play it right, the marriage. There are multiple signals both sides throw out along the way. Some work. Some might work. You do more of what works and less of what does not.

Now watch what most businesses do. They spend every dollar and every ounce of effort on the first two stages. Visibility and engagement. Get seen, get the click, get the first sale. Then the second the ring is on, they ghost.

You would never do that with an actual relationship and expect it to last. Businesses do it every day with their customers and call it a marketing plan.

The maths on why this is stupid has been settled for years. Acquiring a new customer costs roughly 5 to 25 times more than keeping one you already have. A 5% lift in retention can raise profit anywhere from 25% to 95%. That is Bain, that is Harvard Business Review, cited so widely because it keeps holding up. (Invesp)

Here is where marketers lose the room. They hear retention and reach for a points card. A loyalty programme. Some app nobody downloads. That is sprinkles on the cake. It is decoration on top of a problem you have not fixed.

Retention is a capital allocation decision. You have a finite budget. Every dollar you put in changes the taste of the whole thing. The question is not whether you should run a loyalty programme. The question is what your cost tolerance is to acquire a stranger versus what it costs to bring an existing customer back, and why you keep choosing the expensive one.

Look at where the revenue actually sits. Repeat customers can be around a fifth of your base and drive close to 44% of your revenue. Meanwhile the average ecommerce repeat purchase rate sits under 20%. (BS&Co)

Read that again. A small slice of your customers carries almost half your revenue, and most businesses are barely lifting the number of people who come back. You are paying someone to bring a friend, then letting the friend walk out the door and never thinking about it again.

Start by knowing your numbers. Do you know how much of this month's revenue came from someone who has bought before? Most owners cannot answer that. If you cannot see it, you cannot manage it, and right now you are managing it blind.

Then run the comparison. Same investment level, same to same. What does it cost to acquire a new customer versus what it costs to get an existing one to buy again. If the second number is a fraction of the first, and it almost always is, you have found where your next dollar should go. That is not opinion. It is a matter of fact.

Then fix the boring part. The follow up after the first sale. A reason to come back before they forget you exist. Email is where this lives and email returns are among the highest of any channel, but only if you actually use it. Most businesses set it up once and let it rot.

None of this is a campaign. It is infrastructure. Put it in place once so you stop paying full price to re-win people you already had.

When the market was flush, you could paper over a leaky bucket by pouring more in the top. Cheap money, cheap attention, plenty of warm bodies. That is over for a while.

The businesses that come out of the next twelve months stronger will not be the ones who acquired hardest. They will be the ones who stopped the leak. The ones who treated the customers they already had as the asset they are, not as a sale that already happened.

Most people will zig into acquisition harder because that is the muscle memory. If everyone zigs, you zag. Look after the people who already chose you. That is the growth engine hiding in plain sight, and almost nobody is running it.

If you want to see how your own acquisition-to-retention balance compares to your industry, run a Lens scorecard.

Is it really cheaper to keep a customer than to win a new one?

Yes, by a wide margin. Acquiring a new customer typically costs 5 to 25 times more than retaining an existing one, and a 5% improvement in retention can lift profit by 25 to 95%.

Why do most businesses still spend more on acquisition than retention?

Acquisition has an owner, a budget line and visible weekly metrics. Retention sits between marketing, sales and support with nobody clearly responsible, so it gets neglected by default rather than by decision.

Is a loyalty programme the same thing as a retention strategy?

No. A points card is decoration on top of a problem that isn't fixed. The real work is knowing your cost to acquire versus retain and building the follow-up infrastructure, like email, that turns a first purchase into a second.
