Missed calls are one of the few costs a business pays without ever seeing a line item for it.
The spend already happened before the phone rang
Whatever brought that caller to your number — a Google ad, a referral, a review they read — already cost something. A missed call doesn’t just lose the booking; it burns the acquisition spend that produced the call in the first place, with nothing to show for it.
It doesn’t show up in any report you’re already looking at
Revenue reports show what you booked. They don’t show what you didn’t. That asymmetry is exactly why missed calls stay invisible — there’s no dashboard flagging the caller who hung up after four rings and never tried again.
