TL;DR
The cheapest AI answering service is not necessarily the one with the lowest sticker price, since minute caps and per-minute overage fees can turn a $29/month plan into an $80/month plan fast. HireJosie's free plan costs $0/month forever with 15 AI minutes, a dedicated number, 24/7 answering, and real-time Google Calendar booking included, no credit card required. If you outgrow that, Pro is $49/month for 500 minutes with the same full feature set.
Why "cheapest" is the wrong first question
It's tempting to sort every AI answering service by monthly price and pick whatever's at the top. But the sticker price on most of these pages doesn't tell you what a call actually costs once you go past your included minutes, and it doesn't tell you whether the thing you're paying for can book an appointment or just take a message.
A $29/month plan that includes 60 minutes sounds cheap until a business fielding a few calls a day burns through that allotment in the first two weeks and starts paying per-minute overage on top of the base price. A $0/month plan that includes real booking and full features can end up being both cheaper and more useful than a paid plan that nickel-and-dimes you for the features that actually matter.
What actually drives the real cost
Three things determine what you'll really pay each month, and none of them show up clearly in a headline price.
Minute allotment and overage rate. Every plan has a cap, and every plan handles going over that cap differently. Some charge steep per-minute overage, others just switch to voicemail. Either way, the number on the pricing page is only the floor, not the ceiling.
Whether booking happens during the call. A service that only takes a message for someone to call back isn't really saving you money if half those callers book with a competitor before you get to the callback. The cheapest tool that doesn't close the loop on booking can cost you more in lost jobs than a slightly pricier one that does.
Whether the free or entry tier has full features. Some providers gate appointment booking, SMS follow-ups, or after-hours handling behind a higher-priced tier. A low base price is misleading if the features you actually need are add-ons.
- Minute caps that look generous until you count real call volume.
- Per-minute overage charges that kick in the moment you go over.
- Message-taking instead of live calendar booking.
- Features like SMS summaries or emergency alerts gated to paid tiers only.
What free actually looks like at HireJosie
HireJosie's free plan costs $0 a month forever, with no credit card required to sign up. It includes 15 AI minutes a month, a dedicated phone number, 24/7 call answering, appointment booking synced to Google Calendar, warm transfer to a human, emergency alerts, post-call SMS to callers, SMS notifications to you, email summaries after every call, and call transcripts with a dashboard. Nothing on that list is held back for a paid tier.
There's one condition worth knowing: the free plan requires a minimum of three unique customer calls a month to keep the number active. For a business testing the waters with real call volume, that's a low bar to clear.
If your call volume grows past what the free plan covers, Pro is $49 a month for 500 AI minutes, with all free features included, no HireJosie branding, priority support, and no minimum call requirement. Overage after 500 minutes is billed at $0.25 per minute. There are no setup fees and no contracts on either plan, and you can cancel anytime.
How to actually compare "cheap" options
Instead of ranking by the number at the top of a pricing page, run the math against your own call pattern. Estimate how many calls you get a month and how long an average call runs, then multiply that against the minute allotment on each plan you're considering. That tells you whether you're actually looking at a $29 plan or a $29-plus-overage plan.
Then check two things beyond price: does the plan book directly into a calendar during the call, or does it just take a message? And does the entry tier include the features you'd actually use, like after-hours handling and SMS follow-up, or are those reserved for a higher tier? A plan that's cheap on paper but forces a callback loop or gates useful features behind an upgrade often isn't the cheapest option once you account for lost bookings or an unplanned upgrade.
Common Questions
Is there a truly free AI answering service?
Yes. HireJosie's Free plan is $0/month forever with no credit card required, and it includes 15 AI minutes a month, a dedicated phone number, 24/7 answering, Google Calendar booking, warm transfer, emergency alerts, and post-call SMS, all on the free tier.
What's the catch with free AI answering plans?
Usually a minute cap and, in HireJosie's case, a requirement to receive at least three unique customer calls a month to keep the number active. Beyond that, check whether a free or cheap plan actually books appointments live or just takes a message, since that gap can cost you more in lost business than the plan saves you in fees.
What happens if I go over my minutes?
On HireJosie's Free plan, calls switch to voicemail mode once you've used your 15 minutes. On Pro, overage minutes are billed at $0.25 per minute, and most businesses stay well within the 500-minute allotment.
Does the cheapest plan still book appointments automatically?
With HireJosie, yes, appointment booking synced to Google Calendar is included on both the Free and Pro plans, not gated behind a higher tier. That's not true of every provider, so it's worth checking directly rather than assuming.
Is a cheap per-minute plan actually cheaper than a flat-rate one?
Not always. A low advertised price with a small minute allotment can end up costing more once overage fees kick in. It helps to estimate your real monthly call volume and run the math against each plan's cap and overage rate before assuming the lowest sticker price wins.
