The hidden revenue multiplier: how to get your customers to buy more than once (without being annoying)

Most small businesses have a leaky bucket problem.

They work bloody hard to win a customer… and then let them walk out the door after one sale. No follow-up. No re-offer. No long-term thinking. Just a hope they’ll “come back when they need me again.”

It’s the most expensive way to run a business.

Money Lever #3 — Sales Transactions Per Customer — is the ultimate profit unlock.
Get it right, and you increase revenue without finding a single new customer.
Get it wrong, and you’re stuck on the same hamster wheel forever.

Let’s fix that.

Why most businesses are one-and-done

If you’re like most service business owners, you’ve been told to “focus on getting more clients.”
And yes, growth needs new blood — but it’s 5 to 25x more expensive to acquire a new customer than to sell to an existing one.

So why are most businesses obsessed with front-end sales?

Because:

• They don’t have a plan to keep the customer coming back
• Their offers stop at the first sale
• Their systems aren’t set up for post-sale engagement
• They think repeat sales are “pushy” or “salesy”

Here’s the rebel truth: Your best customer is the one you’ve already got.
And if you’re not reselling, rebooking, or re-engaging — you’re leaving serious money on the table.

What this lever really does for your business

Increasing the number of transactions per customer:

• Boosts lifetime value
• Reduces your reliance on constant lead gen
• Creates predictable recurring revenue
• Improves retention and loyalty
• Turns your biz into a machine instead of a hustle

And you don’t have to change who you are to do it. You just need to give your customers more of what they already want.

The rebel fix: how to turn one sale into many

Here’s how to use this lever without sounding like a sleazy car salesperson.

1. Map the customer journey

Look at what happens after the first sale. Ask:

• What else will they need in 30, 60, 90 days?
• What naturally follows the outcome you deliver?
• What can you offer that makes sticking around a no-brainer?

If you’re a service provider, you’re often solving a bigger problem than one session or package can fix. Design your business around the whole journey, not just the entry point.

2. Stack your offers

One sale isn’t enough. You need an ecosystem of offers that build on each other.

That could look like:

• A starter offer → leads to a core service → leads to ongoing support
• A 1:1 service → upsell to a group program or membership
• A one-time audit → leads to implementation packages

You don’t need to invent 15 new products. Just design the next logical step.

3. Automate your follow-ups

Don’t rely on memory or manual reminders. Use your CRM or email system to:

• Trigger upsell or rebooking emails at the right time
• Tag and segment based on purchase history
• Deliver timed value that leads to the next offer

If someone bought once, they’re primed to buy again. Strike while the trust is fresh.

Money maths: how to measure this lever

Tracking this one’s simple — and powerful.

Formula:

Average # of transactions per customer = Total # of transactions / Total # of customers

Say you had 500 transactions across 200 customers last year:

500 / 200 = 2.5 transactions per customer

Now imagine you bump that to 3.5. That’s a 40% revenue increase — no extra leads required.

You should be tracking this:

• Monthly and quarterly
• Per offer (which ones drive repeat sales?)
• By segment (who’s buying the most?)

Real-world ways to boost repeat sales

Here’s what actually works — in real life, not just on a webinar slide.

• Segment your database: Personalise follow-up offers based on what they bought
• Offer bundles and subscriptions: Package ongoing access or repeat delivery
• Use rebooking strategies: Book the next session before they leave the first one
• Automate onboarding: Set expectations for future stages early
• Create a loyalty loop: Give incentives for repeat purchases or referrals
• Survey your clients: Ask what else they need — then build it

Pro tip: Repeat sales aren’t just revenue. They’re relationship capital. The deeper the relationship, the higher the lifetime value — and the easier your business becomes.

Example: turning a one-and-done client into a high-value buyer

Casey runs a creative studio. She offered one-off branding packages — high-ticket, but transactional.

We showed her how to rebuild her offer structure like this:

• Initial brand package → leads to 90-day marketing support
• Monthly design retainer for ongoing clients
• Quarterly strategy check-ins as an upsell

Designed to address her client's specific needs
Designed to triple her annual client value, cut lead gen by half, and stabilised her income.

The lesson? Give people a reason to stay. They will.

What happens if you ignore this lever

If you don’t increase transactions per customer:

• You’ll constantly scramble for new leads
• Your revenue will be unpredictable and feast-or-famine
• You’ll burn time and money replacing people who should’ve stayed
• Your customer experience ends too early — and so does your impact

Basically, you’re rebuilding the business every month. That’s not sustainable — and it’s not freedom.

What to do next (your rebel move)

Start simple. Ask:

• What’s the next step I can offer my existing clients?
• What offer or service would naturally follow their first purchase?
• How can I automate the invitation to that offer?

Even a tiny increase in repeat sales can radically shift your bottom line.
Start with what you’ve got. Optimise what’s already working. Make it easy for people to say yes again.

Final word: repeat sales are your easiest win

This lever isn’t about pestering your customers — it’s about serving them better.
You don’t need to chase strangers when you’ve already got buyers who trust you.

When you unlock this lever, you stop being a “one-hit wonder” business — and start becoming a business they come back to again and again.

Next up? Average sale value. Because the size of each transaction matters just as much as the number of them.

Let’s pull that lever next.
