Missed-call text-back for a pet grooming business
Both hands are on a wet dog and the dryer is running. You are not answering that phone and you should not, because letting go of a soapy spaniel to take a price question is how a dog gets hurt. Groomers miss calls at a rate that would close a plumbing company, and for a good reason.
The cost is different here too. A plumber loses one job. You lose a client who was going to come back every six to eight weeks for years, which at a normal ticket runs past a thousand dollars per new caller who books somebody else.
Text-back fixes it without hiring a receptionist. The moment a call goes unanswered an automatic text goes out that identifies you, apologizes once, and asks a question. Ending with a question roughly doubles replies compared with "we will call you back." Text is the right channel for grooming anyway, since you can answer between dogs and she could not talk either.
Two weeks in, working looks like every missed call showing a reply within seconds and bookings traceable to calls you never picked up. Run your own numbers in the calculator.
