The short answer

Upfirst sells its AI receptionist by the call. Starter is $24.95 a month for 30 calls, Premium $59.95 for 90, Pro $159.95 for 300 and Scale $299 for 600, with extra calls at $1.50, $1.00, $0.75 and $0.70, and annual billing takes 20 percent off. That makes Upfirst the cheaper choice below roughly 120 calls a month. Above that the per-call meter adds up: at 150 calls Upfirst costs $119.95 against PhoneAgent.ai at a flat $89, and at 1,000 calls $579 against $399.

This page puts Upfirst's published pricing at six real call volumes, monthly and annual, next to PhoneAgent.ai, an AI receptionist on a flat monthly fee. It is honest about where Upfirst is cheaper, which is low volume, and shows the call count at which a per-call meter starts costing more than a flat plan.

Upfirst bills an AI receptionist by the call, which is cheapest when the phone is quiet. PhoneAgent.ai bills a flat monthly fee, which is cheapest once the phone gets busy.

Upfirst pricing against a flat fee, at six call volumes

Cheapest Upfirst plan for each volume including its published per-call overage, next to the PhoneAgent.ai plan that covers the same volume. Upfirst figures read from its pricing page on 14 October 2026.

Calls a month Upfirst, monthly billing Upfirst, annual billing (per month) PhoneAgent.ai, monthly PhoneAgent.ai, annual (per month)
50 $54.95 (Starter plus 20 calls at $1.50) $48 (Premium) $89 (Starter) $44.50
100 $69.95 (Premium plus 10 calls at $1) $58 (Premium plus 10 calls) $89 (Starter) $44.50
150 $119.95 (Premium plus 60 calls at $1) $108 (Premium plus 60 calls) $89 (Starter) $44.50
300 $159.95 (Pro) $128 (Pro) $199 (Professional) $99.50
500 $299 (Scale) $240 (Scale) $199 (Professional) $99.50
1,000 $579 (Scale plus 400 calls at $0.70) $520 (Scale plus 400 calls) $399 (Practice) $199.50

Upfirst does not bill spam, calls under 15 seconds or calls where the caller never speaks, so a busy line with lots of hang-ups costs less than the raw call count suggests. Annual Upfirst rows assume overage stays at the monthly rate. PhoneAgent.ai Starter does not include warm transfer; Professional does. Confirm current pricing with each provider before you sign.

Why teams pick PhoneAgent.ai

One AI receptionist that answers, books and routes every call

A bill that does not grow with your calls

About 150 calls are included on Starter and about 500 on Professional, so a busy week or a peak season does not move the invoice.

Half off for paying yearly

Annual billing cuts every PhoneAgent.ai plan by 50 percent. Starter works out to $44.50 a month, which beats per-call pricing from about 50 calls up.

Every call ends with a next step

The receptionist books the appointment while the caller is on the line, and texts back anyone who hangs up before it answers, so a missed call still turns into a lead.

How much does Upfirst cost?

Upfirst publishes four plans and a custom tier. Starter is $24.95 a month for 30 calls, Premium is $59.95 for 90, Pro is $159.95 for 300 and Scale is $299 for 600. Calls past the allowance cost $1.50 each on Starter, $1.00 on Premium, $0.75 on Pro and $0.70 on Scale. Paying annually drops the plans to $20, $48, $128 and $240 a month. Extra agents are $9.95 a month each, and there is a 14 day trial with no credit card.

The headline number is the one most buyers fixate on, and it is genuinely low. But Upfirst is a per-call product, so the number that matters is your call count times the overage rate once you pass the allowance. A shop taking 150 calls a month pays $119.95 on Premium, because 60 of those calls are billed at $1 each. That is the point where a flat fee starts winning. Our AI receptionist pricing page sets seventeen AI receptionist vendors side by side on a cost per call basis if you want the wider field.


Is Upfirst cheaper than other AI receptionists?

At low volume, yes, and it is worth saying plainly. If your business takes 30 to 100 calls a month, Upfirst's Starter and Premium plans are among the cheapest AI receptionists sold in the US, and they include call transfers, booking and Zapier on every tier. PhoneAgent.ai starts at $89 a month, so a business that will never pass 100 calls pays less with Upfirst on monthly billing.

The picture changes in two places. First, volume: between roughly 120 and 300 calls a month the per-call overage pushes Upfirst past a flat $89 plan, and from about 400 calls up the Scale tier and its overage cost more than PhoneAgent.ai Professional at $199. Second, annual billing: Upfirst takes 20 percent off for paying yearly, PhoneAgent.ai takes 50 percent off, so a yearly Starter plan is $44.50 a month for about 150 calls. If your volume is seasonal, also look at the busy month, not the average one. A tax office, HVAC company or landscaper can double its calls in peak season, and a meter bills every one of them.


What does Upfirst include on every plan?

More than most entry-level AI receptionists. According to its pricing page every Upfirst plan includes call transfers to you or your team, appointment booking into Google, Outlook, Clio, Acuity, Calendly and Square, a Zapier connection, support for 35 or more languages with translated transcripts, call recordings and summaries, in-call texting, spam blocking and caller memory. Pro and Scale add white-glove onboarding, and the custom tier adds a BAA for HIPAA-regulated businesses.

Two of those are real advantages over PhoneAgent.ai and you should weigh them. Upfirst books into Clio and Square directly, and it includes call transfer on its cheapest plan, where PhoneAgent.ai keeps warm transfer for Professional and up. If your callers routinely need to reach a person live and you take under 100 calls a month, that combination is hard to beat on price. If you are a law firm comparing intake options, our legal answering service page covers how PhoneAgent.ai handles intake and consult booking without Clio.


Upfirst vs PhoneAgent.ai for a growing small business

Both are AI receptionists that answer on the first ring, take messages, book appointments and send you a summary of each call. The difference is how you pay and what you are buying past the answer.

Upfirst bills per answered call against an allowance, which suits a business with a low, steady call count. PhoneAgent.ai bills a flat $89, $199 or $399 a month with about 150, 500 or 1,500 calls included, which suits a business whose phone gets busier as it grows or in season. PhoneAgent.ai says it is an AI in the first sentence of every call, checks your calendar and books the slot during the call, routes callers by your rules and texts missed callers back so a hang-up still becomes a lead.

The practical test is simple. Pull last month's call log, count the calls, then read the matching row in the table above. If you sit under 100 calls and need transfer on the cheapest plan, Upfirst is the better buy. If you sit above 150, or your busiest month is twice your quietest, the flat fee wins and keeps winning. The best AI receptionist comparison ranks the wider field by scenario, and plans and pricing lists what each PhoneAgent.ai tier includes.

Good questions

Upfirst vs PhoneAgent.ai, answered

Upfirst costs $24.95 a month for 30 calls on Starter, $59.95 for 90 on Premium, $159.95 for 300 on Pro and $299 for 600 on Scale. Extra calls cost $1.50, $1.00, $0.75 and $0.70 depending on the plan. Annual billing lowers those to $20, $48, $128 and $240 a month, and there is a custom tier above 600 calls.
No. Upfirst says it does not bill spam, calls shorter than 15 seconds or calls where the caller never speaks. That keeps robocalls and hang-ups off the meter, which matters on a per-call plan. PhoneAgent.ai includes a set number of calls on a flat fee, so short calls and spam do not change the bill either way.
Yes. Upfirst offers a 14 day trial with full access to the plan you choose and no credit card required, and there is no contract, so you can cancel, upgrade or downgrade at any time. Use the trial to run a week of real calls and count them, because your call volume decides which plan is cheapest.
Upfirst is a good fit for a small business with a low, steady call count, roughly under 100 calls a month, because its entry plans are cheap and include transfers and booking. Businesses with more calls, or a busy season that doubles them, usually pay less on a flat fee AI receptionist such as PhoneAgent.ai.
For a business taking more than about 150 calls a month, PhoneAgent.ai at a flat $89 or $199 a month, which books appointments during the call and texts missed callers back. If you want a human voice instead of AI, live services such as Smith.ai, Ruby and AnswerConnect cost several times more per call but put a person on the line.
