What a customer is really worth
Two customers walk in and each takes the same effort to win. One buys once for a dinar and vanishes; the other stays for ten years. If you treat them the same, you'll over-serve the tourist and lose the client who was worth a fortune.
A customer's worth is not one sale but the whole relationship — their Lifetime Value. A tourist buying a single one-dinar lemonade is worth about one dinar; a car-insurance client at 200 a month for ten years is worth about 24,000. LTV decides how hard you fight to keep someone and how much you can spend to win them.
Multiply average purchase × how often they buy per year × how many years they stay. A 100 purchase, four times a year, for five years = 2,000 of lifetime value. Suddenly a customer isn't a 100 sale — she's a 2,000 asset worth protecting.
This is why subscriptions and retainers are so powerful: they maximize lifetime value automatically by collecting revenue for as long as possible, instead of resetting to zero after every sale. Turning even a slice of your business into a recurring relationship transforms what each customer is worth.
Netflix built its business on lifetime value: a low monthly fee that renews for years, plus disciplined reactivation — emailing lapsed subscribers offers every few months to restart a high-LTV stream. Each returning member wasn't one sale but a relationship reborn.
→ The subscription-plus-reactivation model made it one of the most successful recurring businesses ever, with revenue collected month after month for over a decade per loyal member.
But high LTV isn't a license to abuse it: in 2011 Netflix split its plans and effectively raised prices ~60%, lost about 800,000 subscribers in one quarter, and watched its stock fall ~77%. It recovered — proof that even a beloved subscription can misjudge how much it can push its own customers.
The costly mistake is treating a repeat, relationship customer like a one-time walk-in — under-investing in retention and losing clients who were worth years of income over a small, fixable friction. The customer you already have is almost always cheaper to keep than a new one is to find.
Stop pricing the sale and start pricing the relationship. Estimate each customer type's lifetime value, and pour your best service into the high-LTV ones — the effort you spend keeping them is trivial next to what they're worth.
Pick your most loyal customer type and calculate their lifetime value: average purchase × times per year × years they stay. Write the number down — then design one thing that makes those customers stay a year longer.
Two customers cost you the same to win: one buys once, one stays a decade. What's the name for the difference in their worth, and why do subscriptions maximize it automatically?
