Keeping a customer is worth more than finding a new one

Open your marketing budget. How much goes to finding new customers? And how much goes to keeping — and growing — the ones you already have? For most SMEs, the answer is 100% versus 0%.

That's exactly backwards from what the data says. Frederick Reichheld's work at Bain & Company, published by Harvard Business Review, established it: increasing retention by just 5 points grows profits by 25 to 95%. A retained customer buys more, costs less to serve, and refers you.

Why nobody does it

Because acquisition is visible and retention is silent. A new campaign gets announced. A customer coming back a fourth time makes no noise — until the day they stop coming back, and nobody notices until the financial statements.

Four retention moves that cost almost nothing

• Know who hasn't come back. A simple list of customers inactive for six months is worth gold — most businesses don't have it.
• Share news before it's asked for. A proactive follow-up after the purchase, a useful seasonal reminder: regular communication is the number one reason people stay.
• Reward loyalty before courting strangers. An offer reserved for existing customers almost always outperforms the same offer in cold advertising.
• Ask why people leave. One honest conversation with a lost customer teaches more than ten surveys.

Acquisition remains necessary — no business grows without new customers. But if your budget completely ignores retention, you're filling a leaky bucket, at full price.
