Industry studies put small business missed-call rates around 30 to 40 percent. Most of those callers do not leave a voicemail. They dial the next result on Google.
Run your own numbers: if an average new customer is worth a few hundred dollars and you miss five calls a week, even a ten percent close rate on those calls is thousands a year walking to a competitor.
The fixes stack. Rollover so a busy line rings a second phone. Hours-based routing so after-close calls go somewhere useful. And answering service that picks up when nobody can, then texts you what the caller wanted.
None of that requires hiring anyone. It is configuration, and it costs less per month than one missed job.
