All numbers are estimates based on what you told us above. Lifetime value depends on your repeat rate — the longer a customer stays, the bigger the real cost of missing them at the first call.
Why most solos underestimate this
Missed calls feel small in the moment — “they'll ring back.” But 69% don't leave a voicemail and most go straight to the next business in their search results. The cost isn't one job — it's the lifetime value of customers who never become customers.
