And where Riley fits.
Four ways the phone gets answered, what each one costs, and the dispatch software you can keep.
You, between jobs
You can’t pick up with both hands on the work, and calling back later gives the customer time to call someone else.
Costs you the calls you can’t takeVoicemail
It takes a message. It can’t book the service call, give your hours or tell an emergency from a question.
Free, and it books nothingAn answering service
A live service is priced by the minute or by the call, so a busy month costs more. Ruby charges $3.45–$5.00 a minute; Smith.ai starts at $150 a month for 75 calls, then $2+ a call.
From $150 a month, then per callRiley, on ThreeDay
Answers every call, 24/7, in 30+ languages. Books the service call, texts the confirmation and puts urgent calls through.
