The ideas worth taking with you
- 01
Separate a first sale from a relationship
A first transaction tells you what happened once. Repeat purchases and ongoing service show a different pattern. Review actual customer history instead of assuming every new customer will return.
- 02
Start with a simple revenue estimate
Average purchase value × purchases per year × years retained gives a rough lifetime revenue estimate. For example, $100 × 3 × 2 is $600 in revenue, not profit or a guaranteed future value.
- 03
Look at margin and service costs
Subtract the relevant delivery, servicing, and acquisition costs when judging value. Revenue alone can make an expensive-to-serve relationship look healthier than it is.
- 04
Offer relevant next services
A cross-sell should solve a real need that fits your capabilities. Explain optional services plainly and never make a customer feel they must buy unrelated extras.
- 05
Measure retention with comparable groups
Look at customers who started in a similar period and whether they returned within a meaningful timeframe for your business. A monthly service and a once-a-decade project need different measures.
- 06
Keep referral value separate
Record referrals that actually became enquiries or customers. Do not add imagined referrals to lifetime value, and avoid counting the same revenue twice.
