How do I get repeat sales from existing customers?

How do I get repeat sales from existing customers?
💡 Kısaca: While chasing new customers we forget the ones we have.

While chasing new customers we forget the ones we have. The advertising budget goes entirely to new people while the list of those who already bought sits untouched. 🔁

Repeat purchase is digital’s cheapest channel: you already know the person and trust is already built. It is still the least managed channel of all.

Short answer: loyalty is not a card scheme. It rests on three things — right timing, a reminder, a privilege. 🎯

WHY

Why is repeat purchase so cheap?

Because the hard part of the sale is already done. 💰

HOW

How do you find the right timing?

Timing is repeat purchase’s lifeline. ⏰

HOW

How is the reminder sent?

The channel matters less than the content. 📨

HOW

How is privilege designed?

Loyalty is about treatment more than discounts. 👑

HOW

How is it measured?

Three numbers, one table. 📊

WHAT

What should I do today?

BU BÖLÜMÜN ÖZETİ

  • Step 1: calculate the cycle
  • Step 2: set up one reminder
  • Step 3: separate the dormant list
  • If you want help

Three steps, one day. 🪜

Step 1: calculate the cycle

What is the average gap between two orders? That single number writes your calendar. 🧮

Step 2: set up one reminder

For your best-selling product or service, a single message before the cycle closes. The fastest gain is here. 📨

Step 3: separate the dormant list

List those past twice the cycle and write them a different message. That list is usually surprisingly large. 😴

📝 Notes From the Field

At one online retailer the entire ad budget went to new customers. The order data was examined: the average repeat interval was plainly visible. A single reminder was set to go out before the cycle closed. That month’s highest-converting campaign was the message that cost nothing in advertising.

📖 Short Glossary

Consumption cycle: the average time until a product runs out or needs renewing. Dormant customer: someone past twice the cycle who has not returned. Lifetime value: total profit from a customer across the whole relationship. Privilege: a non-discount, treatment-based loyalty element.

Frequently Asked Questions

Sık Sorulan Sorular

Which cost disappears?

Finding and persuading: the person knows you, knows where you are, and has already paid once. What remains is reminding. 🧲

How valuable are they?

A returning customer usually negotiates less, returns less and produces referrals. Three benefits from one person. 💎

Why is it neglected?

Because it is invisible: a new customer shows up as a number in the panel, while a repeat purchase happens quietly. What is not measured is not managed. 🌑

Where is it strongest?

In any business with a consumption cycle: food, cosmetics, servicing, health follow-up, education, spare parts. 🏪

What is the consumption cycle?

How many days on average until your product runs out or needs renewing? That number writes your reminder calendar by itself. 📅

How is it calculated?

From past orders: the average gap between the same customer’s two purchases. One query gives you the whole campaign calendar. 🧮

When does the reminder go?

Shortly before the cycle closes. A reminder sent after it has ended finds the customer at a competitor. ⚡

How does it work in service businesses?

Through maintenance and check dates: “it’s been six months” is the highest-converting message in service work. 🔧

Which channel?

Whichever they permitted: email, message or phone. Messaging discipline sits in the WhatsApp and SMS guide. 📱

What should it say?

Not a campaign but a reminder: “you bought this on that date, it’s about due”. A message carrying personal information beats a discounted bulk send. ✍️

Is a discount required?

No: with the right timing, no discount is needed. A brand adding a discount to every reminder teaches customers to wait. 🎓

Should it be automated?

Yes: cycle-based reminders should run automatically. A manual reminder gets forgotten in busy weeks. ⚙️

Which privileges work?

Priority, early access, a small free service, personal contact. These cost little or nothing and change perception. ⭐

Are points schemes needed?

Useful in high-frequency businesses; meaningless in low-frequency ones. Nobody collects points on something bought twice a year. 🎟️

How are tiers built?

Keep them simple: two tiers is enough. A complicated tier table goes unread. 🪜

What is the strongest privilege?

Being known: a customer addressed by name whose history is remembered does not go elsewhere. That is a product of record-keeping discipline. 🤝

Which three?

Repeat purchase rate, gap between orders, and customer lifetime value. The third changes budget decisions. 🔢

What is lifetime value for?

It tells you what you can afford to pay for a new customer. Without that figure, ad budgets are set by guesswork; the arithmetic sits in the ROI guide. 💰

How is a dormant customer defined?

One who has passed twice the cycle length. That group is handled separately: the win-back message is written differently. 😴

Which signal is the alarm?

A falling repeat rate. If new customers rise while repeat rate falls, the business is filling a bucket with a hole in it. 🪣

Can this be done without a CRM?

At small scale yes: a table holding order date and customer details is enough. What matters is not software but that records sit in one place and carry dates.

Do reminders annoy people?

Not when the timing is right; they are often received as useful. What annoys people is not the reminder but frequent campaign messages unrelated to their cycle.

Is winning back dormant customers worth it?

It is usually cheaper than finding new ones. But keep it to a single attempt; writing repeatedly to a list that does not respond creates permission and reputation risk.
