## What it costs at your call volume

**Cost at 100 calls a month** · Yes — $90 a month on Business for 100 calls of 2.5 minutes. Includes required fees: AI Receptionist add-on, per agent per month $45.

> Business $45 /month per seat Billed monthly
> — https://www.withallo.com/pricing · Plan cards, Monthly toggle, Business card

**Cost at 500 calls a month** · Yes — $90 a month on Business for 500 calls of 2.5 minutes. Includes required fees: AI Receptionist add-on, per agent per month $45.

> Business $45 /month per seat Billed monthly
> — https://www.withallo.com/pricing · Plan cards, Monthly toggle, Business card

**What it bills by** · Yes — Billing is a flat per-seat monthly fee with unlimited national calling, not per minute or per call; the receptionist itself is an add-on priced per agent.

> Per seat, per month, billed monthly or yearly. Solo is one seat. On Business and Ultra you add seats when your team grows, and you only pay for the seats you use, with no setup fees.
> — https://www.withallo.com/pricing · Frequently asked questions, "How is Allo priced?"

**Past your allowance** · Partly — National calls are unlimited so there is no call allowance to exceed, but international calls and non-US texts are metered against a shared credit balance you top up.

> The Business plan includes unlimited calling at the workspace level, so there's no shared pool to run out of. The AI Receptionist is an add-on billed per agent, not per minute. International calls and texts are paid from credits, one balance shared by the whole team.

## What it does on the call

**Transfers to a person** · Partly — Rules in plain language send a caller to a teammate, another line or an outside number, but the warm transfer that announces the caller first is still labeled beta by the vendor.

> By default, the agent transfers calls directly. Turn on Warm transfer (beta) and the caller waits on hold while Allo rings your teammate, announces the caller's name and reason, and only connects them if they accept.
> — https://help.withallo.com/en/features/ai-receptionist · Transfer rules, "Warm transfer"

**Urgent calls escalated** · Partly — You can write a rule that pushes urgent calls straight to a person, and Allo emails the team when a promised callback has not happened, but there is no documented on-call rota or paging escalation.

> When: the condition, written in plain language. For example "Billing questions go to the office" or "Urgent jobs go straight to me"
> — https://help.withallo.com/en/features/ai-receptionist · Transfer rules, rule parts list

**Human receptionists as backup** · No — Allo staffs no answering service behind the AI: every escape route the vendor documents routes the caller back to your own people or an outside number you nominate.

> Transfer to: a team member, another inbox in your workspace, or an external number
> — https://help.withallo.com/en/features/ai-receptionist · Transfer rules, rule parts list

**Texts your callers** · Partly — Missed callers get an automatic text back and the team holds text conversations in the shared inbox, but outbound texting is a Business-plan feature and only free to US numbers.

> Receiving texts is unlimited on every plan, at no cost. Sending to US numbers is included on Business and Ultra, at no extra cost. Sending elsewhere uses SMS credits, billed by destination.
> — https://www.withallo.com/pricing · Frequently asked questions, "Is texting included?"

## What you get after the call

**Call summary by text** · Partly — Every handled call lands in the app with its summary, and email notifications cover promised callbacks, but the vendor's documentation does not establish an SMS summary to the owner after each call.

> Every call your agent handles lands in your Calls tab, with an AI Receptionist filter to find them fast. Open a call to get: Summary: the key points of the conversation
> — https://help.withallo.com/en/features/ai-receptionist · "After every call" section

**Recordings and transcripts** · Yes — Recording, verbatim transcription and an AI summary start automatically on every call, on every plan, and recording cannot be switched off from inside the app.

> Yes, every call made through Allo is automatically recorded, transcribed, and summarized by AI. You cannot disable recording in-app (contact support if needed).
> — https://help.withallo.com/en/support/faq · Call Features, "Are all calls automatically recorded?"

## What it connects to

**Google Calendar** · No — The vendor names its booking integrations as a closed set of three: Google Calendar, Cal.com and Calendly, so Outlook and Microsoft 365 are not supported for mid-call booking.

> The agent can book meetings for you during the call. It works with Google Calendar, Cal.com, and Calendly.
> — https://help.withallo.com/en/features/ai-receptionist · Meeting booking, opening sentence

**CRM, Zapier and webhooks** · Yes — Native CRM sync covers HubSpot, Salesforce, Pipedrive, Attio and others from the Business plan up, with Zapier, Make, webhooks and a public API for everything else.

> Allo is natively integrated with HubSpot, Salesforce, Pipedrive, Attio, GoHighLevel, Odoo and Google Sheets. Everything else connects through Zapier, Make or the open API (Business and up).
> — https://www.withallo.com/ · Frequently asked questions, "Does Allo work with my CRM?"

**Your trade’s software** · Partly — Trade-adjacent tools are covered through Jobber, JobNimbus and Follow Up Boss, but the documented integration catalog names no ServiceTitan, Housecall Pro, Dentrix, Clio, OpenTable or Mindbody.

> Jobber: Automatically sync call recordings and summaries to your Jobber clients

## Trying it, starting and leaving

**Free trial or free plan** · Partly — You can run Allo on a real line for seven days on the Business plan before paying, but outbound calling is capped and international calls are switched off during that window.

> 7 days, on the Business plan. Full access to the apps and features: desktop, mobile, team features
> — https://help.withallo.com/en/billing/free-trial · "The basics" bullet list

**Card required to start** · Yes — A valid card is taken at signup and charged when the seven days end, with one reminder email the day before the charge.

> Credit card required, and you won't be charged until the trial ends. You get an email reminder 1 day before the charge, and you can cancel anytime during the trial.
> — https://help.withallo.com/en/billing/plans-and-pricing · Free trial card, "Try Business free for 7 days"

**Sign up without a sales call** · Yes — Business is bought and configured from the app without talking to anyone; only the Ultra tier and larger migrations route through sales.

> No. Business starts in minutes, straight from the app, and Solo will too when it opens: join the waitlist on its card. Ultra and larger migrations get a dedicated onboarding when you contact sales.
> — https://www.withallo.com/pricing · Frequently asked questions, "Do I have to talk to sales to start?"

**Setup fee** · No — No onboarding or setup charge on any plan; the only one-time fee is the $24 US carrier registration a number needs before it can text.

> No setup fees and no contracts. You pay only for what you use and can upgrade, downgrade or cancel anytime, with no lock-in.
> — https://www.withallo.com/pricing · Frequently asked questions, "Are there setup fees or contracts?"

**Contract and cancelling** · Yes — Month-to-month is offered on every plan and you cancel yourself from Settings, keeping access to the end of the paid period; yearly billing is optional, not required.

> Cancel anytime from Settings > Billing (web/desktop) or Settings > Profile > Manage Subscription (iOS). You keep access until the end of your billing period.
> — https://help.withallo.com/en/support/faq · Plans & Billing, "How do I cancel my subscription?"

## Which languages it speaks, and how it sounds

**Languages** · Partly — Marketing claims several languages including Spanish, while the help center limits the agent's voices to English and French, so coverage beyond those two is not established.

> The agent speaks the language of the voice you pick. Choose the language first, then the voice, in the Personality settings. Voices are available in English (US and UK) and French (France and Canada).
> — https://help.withallo.com/en/features/ai-receptionist · "Languages" section

**Choose or clone the voice** · Partly — You pick a language and then an ElevenLabs voice and listen before choosing, but a voice built for your own brand is an Ultra-tier item and no voice cloning is offered.

> Voice: pick a language, then a voice. You can listen to each one before choosing.
> — https://help.withallo.com/en/features/ai-receptionist · Set up your agent, step "Shape its personality"

**Hear it before you buy** · Yes — Recorded sample calls play on the product page, an AI agent answers the published sales line, and you can place a test call to your own agent before going live.

> An Allo agent picks up and puts you through to sales or support. It is the fastest demo on this page.
> — https://www.withallo.com/pricing · Frequently asked questions header, beside 888-298-ALLO

## Your phone number and where it works

**Keep your number** · Yes — You keep your existing line and forward it to Allo, which the mobile app tries to configure with your carrier automatically, and all AI features then apply to those calls.

> Call forwarding redirects incoming calls from your personal number to your Allo number.
> — https://help.withallo.com/en/phone-numbers/connect-personal-number · "How it works" section

**Move your number in** · Yes — Porting in is free and handled with your carrier for you, taking a few business days, and the help center documents a separate route for porting a number back out.

> Allo charges nothing to port your number. Your ported number is included in your existing plan with no extra monthly fee.
> — https://help.withallo.com/en/phone-numbers/port-existing-number · "Costs" section

**Australia** · Yes — US and Canadian numbers activate instantly, UK and Australian numbers take a few days with proof of address, EU countries are covered with local documents, and the vendor states GDPR compliance.

> Allo offers business phone numbers in 120+ countries. Some are instant. Others require local business documents.
> — https://help.withallo.com/en/phone-numbers/international-numbers · Info callout above "Get a Number Instantly"

## Who it is built for

**Industries it is set up for** · Partly — Presets are written by job (receptionist, support, lead qualifier, appointment setter) rather than by trade, and the trade pages the vendor publishes say one setup suits them all.

> The same setup works whether you run a real estate office, a law firm, an HVAC or plumbing company, a medical practice or any small business that lives on the phone.
> — https://www.withallo.com/product/ai-receptionist · Before you start, "What does an AI receptionist do?"

**HIPAA, with a signed BAA** · Partly — A Business Associate Agreement is signed for healthcare customers, but only as a paid workspace add-on and only on the Business and Ultra plans.

> Yes, if your business handles patient information. The BAA is a $50 per month add-on for your whole workspace, on Business and Ultra.
> — https://help.withallo.com/en/billing/plans-and-pricing · Frequently asked questions, "Do you sign a HIPAA BAA?"

**Several locations or numbers** · Yes — One workspace can run several lines, each with its own agent and rules, and extra numbers start at $5 a month each on any plan.

> Each line gets its own agent. The agent you configure belongs to the line you are currently on, so a support line and a sales line can run two different receptionists.
> — https://help.withallo.com/en/features/ai-receptionist · "What the AI receptionist does", closing paragraph

## Getting set up and getting help

**Setup help** · Yes — Setup is a guided self-serve flow said to take minutes with no technical skills, while custom onboarding with an account manager is reserved for the Ultra plan.

> Most teams take their first calls on Allo the same day. Setup is guided and needs no technical skills.
> — https://www.withallo.com/pricing · Frequently asked questions, "How hard is it to switch from my current phone system?"

**Support** · Yes — Email support is on every plan, live chat and priority support from Business, Slack and a named manager on Ultra; a sales line is published but support hours are not stated.

> Open web.withallo.com and click the chat widget to start a conversation. Our team typically replies within a few minutes during business hours.
