Reputation helps. People still need to find it.
A strong team, loyal buyers and twenty years of experience are real assets. New customers may not know you: they search Google, maps, websites or AI. New competitors can appear alongside you with a clearly explained offer.
Not every newcomer takes your customers, but company age does not reserve search positions. Check what a new buyer sees: current services, contacts, real work, terms and convenient enquiry options.
Word of mouth works. Depending on it alone is risky.
Referrals bring trust but are hard to forecast. Needs, customer staff, seasons and social circles change. When enquiries fall, having no other channel becomes a problem.
A website and marketing can support referrals: recommended buyers check you online. Useful pages, real projects and clear terms reinforce trust. Measure new-client sources before choosing which channel to strengthen.
LTV: what a customer contributes over the relationship
LTV means customer value over a relationship period. Reports may use revenue or financial contribution. For advertising decisions, revenue alone is insufficient. Here we use payments minus direct and variable fulfilment, delivery, fees, returns and retention costs.
Customers may return, add a service or buy regularly, but order history must support this. Do not assume five years of purchases to make returns look attractive. Start with actual contribution at 3, 6 and 12 months.
CAC: customer cost, not lead cost
CAC is acquisition spending divided by new customers over an agreed period. Include ad spend, management, creative and attributable sales work. Decide separately how shared costs and one-off investment are allocated.
Example: €2,000 spent to acquire ten buyers gives €200 CAC. One hundred leads means €20 per lead, not per customer. For long sales cycles, match spending to the customer cohort it acquired, not simply current-month payments.
A loss-making first sale can fit a working model
Assume €300 revenue and €220 fulfilment and variable costs. Contribution before acquisition is €80. With €100 CAC, the first order contributes −€20 after acquisition. Returning customers may change the outcome.
Of 100 customers, 30 place another identical order within six months. Initial contribution: 100 × €80 = €8,000. Repeat: 30 × €80 = €2,400. Acquisition: 100 × €100 = €10,000. The cohort leaves €400 before fixed costs and taxes: a small buffer, not guaranteed €60 profit per customer.
If only 20 return, the outcome is −€400. The decision depends on verified repeats, costs and payback timing. Even positive six-month contribution may not cover today's office, payroll and cash gap.
First purchase: $15. Repeat purchases change the economics.
Another illustration: the customer pays $100, direct product or service cost is $60, and Google acquisition costs $25 per new buyer. $100 − $60 − $25 leaves $15. This is contribution after acquisition, not net profit; taxes, rent, overheads and costs outside the $60 still need covering.
If the customer returns for another $100 purchase with $60 direct costs, it contributes $40 before other expenses, provided no additional acquisition or retention spending is needed. Three purchases contribute $15 + $40 + $40 = $95. Subtract any return advertising, discounts or other costs. A second visit is not automatically free to acquire.
This is particularly useful for naturally repeated services such as manicures, haircuts and maintenance. Dental repeat visits depend on patient needs; calculations must not encourage unnecessary treatment. Verify actual return rates and timing rather than promising visits.
Quality at every subsequent visit is the key asset. Deliver what you promised, keep prices clear, help customers and solve problems. Ads bring the first visit; the business builds the relationship. Later visits can improve payback, but net profit depends on all costs and actual repeats.
When future LTV cannot justify advertising
If purchases are rare, customers rarely return or service consumes the margin, do not continually fund first-order losses on hope. Kitchens or canopies may have distant repeat demand; focus primarily on order economics. Count referrals separately only when traceable.
Compare cohorts by first-order month and channel. Track repeats, returns, contribution and payback. Set test-spend limits and an acceptable payback period in advance. There is no universally safe CAC.
Long relationships start after payment
Deliver your promises on time, help customers use the product and resolve problems promptly. Service reminders should be relevant; marketing messages need the required permission. Endless discounts do not replace quality.
Start by collecting order history, calculating contribution and repeat rates, and checking the website and enquiry handling. Then run a limited marketing test. Investing in customers makes sense when you understand how and when it pays back.
