What Is an Answering Service?

An answering service is an outside company that answers your business phone when you can't. Calls forward to its agents, who greet callers in your company's name, take messages or book appointments using your script, and pass the details to you by text, email or app. Most charge per minute or per call.

How does an answering service work?

An answering service works by call forwarding. You tell your phone carrier or VoIP system to send calls to the service's number under conditions you choose. An agent answers with your greeting, follows a script you approved, and sends you the result: a message, a booked appointment, or a live transfer for emergencies.

1. 1

   Pick your coverage.

   All calls, after hours only, lunch and overflow, or "ring my cell four times, then forward." Most trades shops start with after-hours and overflow.

2. 2

   Write the script.

   Greeting, questions to ask (name, address, callback number, problem, urgency), what counts as an emergency, and who to call for one. Our HVAC CSR script is a good starting point.

3. 3

   Set the handoff.

   Decide how you get messages (text, email, app) and the on-call number for emergencies. Test it at 2 a.m. once, for real.

4. 4

   Review and tune.

   Read the first two weeks of messages. Fix questions agents keep fumbling and anything they're telling callers that you didn't approve.

What are the types of answering services?

There are three common types: live answering services staffed by people in a call center, virtual receptionist services that act more like a remote front desk, and AI answering services that use a voice agent. Pricing, quality and what they can do differ more between these types than between brands.

The virtual receptionist comparison and AI receptionist vs. answering service go deeper on each choice.

How much does an answering service cost?

A live answering service usually costs a few hundred to a few thousand dollars a month depending on volume. Public plans checked in October 2026 ranged from $99 for 50 minutes to $1,725 for 500 minutes, while AI services started under $50 a month. Per-minute billing punishes long calls, so know your average call length.

Do contractors need an answering service?

Most contractors who can't answer live during the workday or after hours benefit from some form of answering service, because callers with urgent problems rarely wait for a callback. The question is which type. Shops with frequent emergencies need reliable live escalation; shops with mostly routine bookings can often use AI.

Answering service vs. voicemail

An answering service puts a voice on the line; voicemail asks the caller to do the work. Many callers hang up rather than leave a message, and a homeowner with water on the floor will dial the next plumber instead. A cheaper middle step is a missed-call text back that texts the caller within seconds.

Common mistakes when using an answering service

• No emergency definition. If the script doesn't say what's urgent, agents either wake you for everything or nothing.
• Treating messages as booked work. A message is a lead, and leads go cold fast. See speed to lead.
• Ignoring call length. Per-minute plans get expensive when agents chat or callers ramble.
• Not telling callers the call may be recorded. Several states require everyone's consent to record. Make sure the service's greeting handles it.
• Never auditing. Call your own line after hours once a month and see what a customer experiences.
