Answering Service Cost: A Complete Pricing Guide

Before comparing numbers, you need to know which model a provider uses, because the same monthly bill can mean very different things. Here is how each model works and what to watch for.

Per-call pricing charges you a set amount each time the service handles a call, no matter how long the call lasts. Smith.ai, for example, uses per-call pricing for its human virtual receptionist service, with costs depending on the needs you select. Under this model, your total does not change with call length, so a two-minute call costs the same as a ten-minute one.

Per-minute pricing charges for the time the service spends on each call. Your total scales directly with call length, which makes costs harder to predict, because a single chatty caller can use more minutes than three quick ones.

Flat monthly plans bundle an included allowance of calls or minutes into one predictable price, with overage charges beyond the allowance. Ruby, a human virtual receptionist provider, advertises plans starting at $245 per month as of October 9, 2026. AllDayDesk uses this model with included minutes, as described below. A starting price is never the whole story: always check what the allowance covers, what overages cost, what hours are included, and whether there is a contract.

• Per call: total is independent of call length
• Per minute: total scales with call length, harder to budget
• Monthly plan with allowance: one predictable base price, but check overage rates

AllDayDesk is an AI receptionist that answers business calls around the clock using the business details you save. You keep your existing public phone number by forwarding calls to it, and setup involves choosing your business or entering its website, checking the details it found, hearing a personalized sample, and choosing how to forward your phone. AllDayDesk publishes three plans, and the pricing is displayed separately from this article:

The pricing display with this article shows each plan's monthly price, included minutes, and per-extra-minute rate. Solo is the smallest plan with the fewest included minutes, Starter is the mid tier, and Pro includes the most minutes with the lowest overage rate.

Notice the pattern: the bigger the plan, the more included minutes and the lower the overage rate. If your typical call runs about two minutes, an allowance of 200 minutes covers roughly 100 calls a month, 600 minutes covers roughly 300 calls, and 1,200 minutes covers roughly 600 calls. Those are hypothetical illustrations, not guarantees of your call length. Calls, transcripts, summaries, and bookings all appear in your dashboard, so you can check real usage after a month and see which plan actually fits.

The sample greeting you hear during setup creates no real booking, and new appointments go to the built-in AllDayDesk calendar by default once you have configured your services and availability. An optional Google Calendar connection is available in Settings after you connect and authorize your account.

• Solo: smallest plan, fewest included minutes, highest overage rate
• Starter: mid-tier plan, mid-range included minutes and overage rate
• Pro: largest plan, most included minutes, lowest overage rate

The most common budgeting mistake is comparing plan prices without doing the overage math. Here is a worked example using clearly hypothetical numbers, so you can repeat it with your own figures.

Suppose a provider's smaller plan includes 200 minutes at a hypothetical $0.50 per extra minute, and a mid plan includes 600 minutes at $199 per month. If your business gets 250 answered calls averaging two minutes, that is 500 minutes of usage. The smaller plan would leave 300 overage minutes, adding $150 on top of its base price. The mid plan's 600 included minutes would cover all 500, so its bill would be its flat $199 with no overage. The mid plan wins in this scenario even if the smaller plan has the lower sticker price.

Now flip it: suppose you get 80 calls a month averaging two minutes, or 160 minutes total. The smaller plan covers everything at its base price, while the mid plan's higher monthly fee buys nothing you use. The lesson is that the cheapest plan is the one whose allowance matches your actual usage, not the one with the lowest monthly price.

To do this for your own business, estimate three numbers: how many calls you want covered, your average call length, and your monthly total minutes. Then compare each plan's total cost at that usage level, including overages. If the provider offers a usage dashboard, recheck with your real numbers after the first month, which is far more accurate than any estimate.

• Estimate monthly calls, average call length, and total minutes
• Price each plan at that usage level, overages included
• Recheck with real dashboard usage after a month

Human answering services pay trained people to answer your line. Ruby advertises human virtual receptionist plans starting at $245 per month, and AnswerConnect offers 24/7 live business answering by people. Smith.ai's human receptionist service prices per call, with costs depending on the needs you select. Smith.ai also offers a separate AI receptionist product, which shows how the same provider now sells both types at different price points.

AI receptionists like AllDayDesk answer calls themselves using the business information you save, and are sold as monthly plans with included minutes. The tradeoff is not just price. A human service can handle judgment-heavy conversations and nuanced caller situations. An AI receptionist answers consistently around the clock, takes detailed messages, answers questions from your saved details, books appointments, and transfers calls when you configure a destination and rules. When it does not know an answer, a price, or an appointment, it takes a message rather than guessing. Changes to existing appointments are passed to you as requests, not confirmed changes.

For in-house comparison, note that a receptionist's job includes greeting visitors and office tasks beyond phone answering, according to the US Bureau of Labor Statistics, so a phone service is not a full employee replacement. Compare scope, not just cost, and note that no wage figure is quoted here because none was verified for this guide.

• Human services: judgment and nuance; Ruby advertises plans starting at $245 per month
• AI receptionists: consistent around-the-clock coverage, messages when unsure, monthly plans with included minutes
• Neither replaces the full scope of an in-house receptionist job

Whatever provider you consider, get written answers to these questions before committing. They apply equally to human and AI services.

Ask what the included allowance covers and what counts against it. Ask what overages cost and whether you are notified as you approach your limit. Ask whether the advertised price includes the hours you need, since 24/7 coverage is sometimes a separate tier. Ask about setup fees, minimum contracts, and cancellation terms. Ask how appointments are booked, what calendar connections are supported, and how changes to existing appointments are handled. Ask what happens when the service cannot answer a question, and how messages reach you. For transfers, ask what destination and rules you must configure, and understand that neither pickup nor an immediate response is guaranteed.

For AI receptionists specifically, ask to hear a personalized sample before committing, and ask how the service handles unknown prices and unknown appointment availability. A good answer is that it takes a message instead of guessing.

• What does the allowance include, and what do overages cost?
• Are the hours I need in the base price?
• Any setup fees, contracts, or cancellation penalties?
• How are bookings made, and which calendars connect?
• What happens when the service does not know an answer?

If budget is tight, you have several options, each with a real tradeoff. A plain voicemail system is nearly free, but it cannot capture details, answer questions, or book the job; a caller who hangs up without leaving a message is lost. An auto attendant routes callers through a menu, which costs little but offers no conversation. An AI receptionist adds conversational answering, messages, and booking at a monthly rate. A human service adds human judgment; Ruby, for example, advertises human receptionist plans starting at $245 per month, so compare actual quotes rather than assuming any category is always more or less expensive.

Shopping only on the lowest price has hidden costs. A plan with a small allowance can trigger overage charges that exceed the savings. A service that cannot book appointments or answer basic questions from your saved details may push callers to voicemail anyway. And a service that guesses at prices or availability creates problems that cost more than the monthly fee.

The practical approach is to pick the cheapest option that still answers your callers' actual questions, captures complete messages, and books appointments the way you want. When comparing plans, a mid tier can be the better value if the bottom tier's allowance would trigger overages at your call volume, so run the math above before choosing. If you only need backup coverage when you cannot pick up, conditional forwarding to an answering service is a middle ground between voicemail and forwarding every call; compare its cost against full forwarding with your provider.

• Voicemail: cheapest, but no answers, details, or booking
• Auto attendant: cheap routing, no conversation
• AI receptionist: monthly plans with included minutes, answers, messages, booking
• Human service: human judgment; Ruby advertises plans starting at $245 per month, so compare quotes
