You can't answer the phone from a roof. Or mid-quote, or in a ceiling cavity, or at your kid's swimming carnival. So the call rings out, goes to voicemail — and most callers won't leave one. They hang up and ring the next number on the list, and somebody else's week just got better.
The maddening part is you never find out. A missed call doesn't send you an invoice for the job you didn't get. It's just quiet — a coin that got tossed and landed while you weren't looking.
Your options have traditionally been: hire someone (a wage for a phone that rings in bursts), let it ring (see above), or divert to an answering service. This page is about the third option — what a phone answering service actually does, what the traditional ones cost, and how Giday's version is different: it doesn't just catch the call, it finishes the job the call was about.
