Answering Services for Small Business: True Costs

Answering services are priced to be hard to compare: per minute here, per call there, bundles everywhere. The way through is unit economics. What does one answered call cost, and what do you get for it? (Advertisers pay up to $216 per click on this search; the industry can afford it because confusing pricing is profitable.)

The four service types, decoded

Type	Billing	~Cost per 3-min call	What you get per call
Traditional answering service	$1–2/min	$3–6	A relayed message
Virtual receptionist (human, Ruby-class)	Minute bundles ($200–700/mo for 50–200 min)	$4–12	A message, warmer delivery. Full explainer
AI answering	Base plan with included calls, $39–$300/mo	Falls as volume rises: roughly $0.90–$1.30 per call at 100+/mo	Intake done, appointment booked
DIY (voicemail + text-back)	$0	$0	A fraction of callers held, none answered

The structural difference: human services charge more when you get busier; flat AI charges the same. And “what you get per call” differs in kind. A message still costs you a callback (the message-vs-booking distinction is the real decision).

Worked example: 60 calls a month

• Traditional at $1.50/min × 3 min: ~$270/mo, output: 60 messages to return.
• Virtual receptionist 100-min bundle: ~$300–400/mo, output: 60 warmer messages to return.
• AI answering: a plan covering 60 calls lands under $100/mo across the market. Our own Pro plan is $89 and includes 100. Output: intakes completed, bookable calls booked, summaries texted.
• DIY floor: $0, output: the 15% who engage with voicemail plus whoever the text catches.

How to choose without regret

Count one month of real calls (your phone bill knows). Under ~20 calls/month, per-minute billing is genuinely cheapest. Over that, compare flat options, and weigh the callback labour a message-only service leaves on your desk. Then check the cost of doing nothing in the calculator; it’s usually the largest number in the comparison.
