A year of missed calls, by trade
Careful estimateUp to a typical shop
How we worked these out
Missed calls a month = new-customer calls a week × 4.33 × share missed × share who hire someone else × share that would have booked × average job. A year counts the trade's busy months. Office work = hours a week × 4.33 × what an hour is worth: C$35 for office help in the careful estimate, the trade's own hourly rate for a typical shop.
Share missed: 14% (careful) or 27% (typical), from US call benchmarks. Share who hire someone else: 40% or 60%, our assumption: few callers leave a voicemail, so most are only reached if you call back from the log in time. Calls a week are an example for a small shop; change them to yours.
