# Quo (formerly OpenPhone)

> Quo, known as OpenPhone until September 2025, is a cloud business phone system for small teams that gives each user a work number for calling and texting on iOS, Android, desktop, and web, with shared numbers, a threaded inbox for calls and SMS, AI call summaries and transcripts, an autonomous voice and text agent called Sona, and two-way logging into HubSpot and Salesforce, starting at $15 per user per month on annual billing.

## Overview

Quo began life in 2018 as OpenPhone, a Y Combinator company built on a simple observation: small businesses were running their phone lives out of personal mobile numbers, and the moment a second person needed to see a customer conversation the whole thing fell apart. The answer was a work number that behaves like a shared inbox. Calls, voicemails, and text threads land in one place, teammates can be assigned to a thread, internal comments sit alongside the customer messages, and nothing is trapped on one person's handset.

In September 2025 the company renamed itself Quo and announced $105M in growth financing, $96M of it from General Catalyst's Customer Value Fund plus $9M in equity from existing investors. The rename signals a repositioning from business phone system to what the company calls the AI front office, with Sona, an autonomous agent that answers calls and texts, captures leads, answers routine questions, and books work when nobody picks up. The underlying product is the same one tens of thousands of small businesses already use, which matters more than the marketing category.

For outbound sales specifically, Quo is the least aggressive product in this category. There is no power dialer, no parallel dialing, no local presence pool, and no answering machine detection. What it does have is clean per-seat pricing, unlimited calling and messaging to US and Canadian numbers on every tier, automatic recording and transcription from the Business plan up, and CRM logging into HubSpot and Salesforce. It is a phone system with sales manners rather than a dialer.

The commercial shape is the friendliest in the category. Starter is $15 per user per month annually or $19 monthly, Business is $23 annually or $33 monthly, Scale is $35 annually or $47 monthly. Every seat includes a number. Extra numbers are $5 a month each. A seven-day free trial is self-serve and there is no seat minimum, so a solo operator can sign up on a Tuesday afternoon and be taking calls on a work number the same day.

## How it works

1. You sign up, pick a local or toll-free number, or port an existing one, and install the apps. Every user gets at least one number included in their seat, and numbers can be shared so that several people answer and reply from the same line without anyone forwarding calls to a personal mobile.

2. Incoming calls and texts land in a threaded inbox that looks more like a messaging app than a phone console. Each contact has one conversation history covering calls, voicemails, SMS, and MMS. Teammates can leave internal notes on a thread, assign it, or take it over, which is the feature that makes a shared number work in practice rather than in theory.

3. Routing is configured with ring groups, simultaneous ring, phone menus, and business hours, so a two-person company can present a front desk without hiring one. Auto-replies, snippets, and scheduled messages handle the repetitive text work, and automation credits included with every plan cover the triggered messaging.

4. After a call, Business and Scale plans generate an AI summary and a transcript, apply call tags on Scale, and push the activity into HubSpot or Salesforce so the record updates without anyone typing it. Sona, the AI agent, can pick up what humans do not: answering after hours, qualifying an inbound lead by text, and handing the thread back with context attached.

## Best for

Small businesses, agencies, trades, and founder-led sales teams who need a shared work number with texting, light routing, and CRM logging, and who make dozens of calls a day rather than hundreds. Anyone who wants a business phone that costs less than a lunch per seat and can be live in an afternoon.

## Not the right fit for

- Outbound teams who need a dialer. There is no power dialer, no parallel dialing, and no answering machine detection, so a rep working a 400-name list will burn the day on manual taps while a Kixie or PhoneBurner user finishes by lunch.
- Anyone who needs local presence dialing from a rotating pool of area-code-matched numbers; Quo sells extra numbers at $5 a month but has no rotation engine or spam remediation service behind them.
- Heavy international callers. Unlimited calling covers the US and Canada only, and everything outside that is billed per minute and per message at destination rates that add up fast on a European or LATAM territory.
- Contact centres that need queues, skill-based routing, wallboards, service levels, and workforce management; this is a small-business phone, not a CCaaS platform, and it will run out of road above about 30 agents.
- Regulated buyers who need in-region data residency, a signed enterprise security package, and SSO as table stakes; Quo's compliance surface is sized for SMBs, not for a HIPAA or FedRAMP procurement.

## Features

### Numbers and shared inbox

The part of the product that actually differentiates it from a VoIP line.

- **One number included per seat**: Every user gets a local or toll-free US or Canadian number in the seat price, rather than paying a separate DID fee per line as most business phone vendors charge.
- **Shared numbers**: Several teammates can answer and reply from the same number, which is how a two-person company presents a support line without forwarding calls to somebody's mobile.
- **Threaded conversation inbox**: Calls, voicemails, SMS, and MMS with a contact all live in one thread, so the history is a conversation rather than a call log next to a message log.
- **Internal comments and assignment**: Teammates can comment inside a thread and assign it to an owner. The customer never sees the notes, and handoffs stop losing context.
- **Additional numbers at $5 a month**: Extra numbers for departments, campaigns, or second locations are $5 per number per month on any plan, with no per-number setup charge published.
- **Number porting**: Existing business numbers can be ported in, so the switch does not require reprinting anything or updating a Google Business Profile.

### Calling, routing, and messaging

Front-office plumbing sized for a company without an IT department.

- **Unlimited US and Canada calling and messaging**: Included on every tier including Starter, which removes the per-minute modelling that dominates buying decisions in this category.
- **Ring groups and simultaneous ring**: Route a number to a set of people at once or in sequence, with per-person and per-time-of-day rules.
- **Phone menus and auto attendant**: Business and Scale add IVR menus so callers self-route, which also filters a meaningful share of spam calls before a human hears them.
- **Call transfers and group calling**: Warm transfers and three-way calling arrive on the Business tier; Starter is deliberately a solo-shaped plan.
- **Auto-replies, snippets, and scheduled messages**: Canned responses, saved snippets, and send-later scheduling turn repetitive texting into two clicks instead of retyping.
- **Automation credits included**: Every plan includes 1,000 automation credits a month for triggered workflows, with automated SMS billed at roughly a cent per segment beyond that.
- **Voicemail transcription**: Voicemails arrive as text on every tier, including Starter, so nobody has to listen to a two-minute message to learn a callback number.

### AI: Sona, summaries, and transcripts

The layer the 2025 rebrand was built around.

- **Sona AI agent**: An autonomous voice and text agent that answers when nobody picks up, captures lead details, answers routine questions, and hands the thread back with context. Included on every tier with a credit allowance.
- **AI call summaries**: Business and Scale generate a short recap of what was discussed and what was agreed, attached to the conversation thread.
- **Call transcripts**: Full transcription of recorded calls, searchable alongside the message history rather than sitting in a separate recordings archive.
- **AI call tags**: The Scale tier auto-tags calls by topic or outcome, which is the closest Quo gets to conversation intelligence.
- **AI-drafted text replies**: Suggested responses for inbound messages, drafted from the thread context so the reply is about this customer rather than a generic template.

### Recording, CRM, and reporting

Where phone activity turns into a record somebody else can read.

- **Automatic and on-demand call recording**: Auto-record every call on Business and Scale, or record selectively from any device. Recording notification is the customer's responsibility to configure per jurisdiction.
- **HubSpot and Salesforce logging**: Calls, texts, recordings, and summaries write back to the CRM record from the Business tier, which is the tier most sales-adjacent teams end up on for exactly this reason.
- **Slack, Zapier, and Gong connectors**: Notifications into Slack, general-purpose automation through Zapier, and a Gong connector for teams already running conversation intelligence elsewhere.
- **Public API and webhooks**: API access is included on every tier including Starter, which is unusually generous and makes custom logging practical without upgrading.
- **Analytics dashboards**: Call and message volume, response times, and per-teammate activity on Business and Scale. Useful for staffing decisions, not for pipeline forecasting.

### Deliverability and compliance surface

The regulatory bits a US business phone cannot avoid.

- **A2P 10DLC registration handled in-product**: US carrier registration for business texting is done through Quo, with a one-time fee around $19.50 and a recurring carrier charge of roughly $1.50 to $3 a month depending on campaign type.
- **Spam filtering on inbound**: Auto attendant and menu routing screen a large share of robocalls before they reach a person, which is the practical anti-spam story on a small business line.
- **Recording consent controls**: On-demand recording exists precisely so teams in two-party consent states can record only where they have asked; the announcement itself is left to the caller.
- **Per-user permissions**: Control who can see which numbers and threads, which matters as soon as a shared inbox holds customer payment details or complaints.

## Use cases

- **Two-founder startup taking inbound demos**: Prospects call a personal mobile, texts land on whichever founder gave out their number, and nothing reaches the CRM. Outcome: One shared Business-tier number rings both founders, every call is recorded and summarized, the HubSpot record updates itself, and either founder can pick up a thread the other one started.
- **Home services company with a dispatcher**: Missed calls at 7pm are lost jobs, and the owner cannot answer the phone from a roof. Outcome: Sona answers after hours, captures the job details and address by text, and the dispatcher works the queue in the morning from the shared inbox with full transcripts.
- **Agency account team with client-specific lines**: Five clients each want a dedicated number, and account managers keep leaving voicemails on each other's phones. Outcome: Five numbers at $5 a month each route to the right ring group, each with its own auto-reply and business hours, and internal comments keep handovers clean during holidays.
- **Founder doing light outbound follow-up**: Forty calls a week to inbound leads, each needing a text follow-up and a CRM note. Outcome: Click to call from HubSpot, snippet-driven follow-up texts, automatic summary and logging afterwards. Below roughly 60 dials a day this is enough; above it, a real dialer starts paying for itself.

## Pricing

Per-user per-month subscription with a number included in every seat, unlimited US and Canada calling and messaging on all tiers, and usage-based charges only for international calling, extra numbers, automated SMS, and AI credits.

- **Starter**: $15 per user per month billed annually ($19 monthly). One number per user, unlimited US and Canada calling and messaging; Voicemail transcripts; Sona AI agent with 1,000 automation credits; API access; Email support. A complete solo phone. No call recording, no CRM connectors, no phone menus.
- **Business**: $23 per user per month billed annually ($33 monthly). Everything in Starter; AI call summaries and transcripts; Automatic call recording; HubSpot and Salesforce integrations; Phone menus, group calling, call transfers, analytics. The tier almost every team actually needs; the CRM logging and recording live here.
- **Scale**: $35 per user per month billed annually ($47 monthly). Everything in Business; AI call tags; Onboarding support; Priority support; Inbound phone support from Quo. Buys support and tagging rather than meaningful new capability. Most SMBs can stay on Business.

Add-ons:

- Additional phone number ($5 per number per month)
- Sona AI credits ($0 to $199 per month for 1,000 to 60,000 credits): Overage runs roughly $0.45 to $1.00 per call depending on the bundle.
- Automated SMS (About $0.01 per segment): Beyond the included 1,000 automation credits.
- A2P 10DLC carrier registration (About $19.50 one-time plus $1.50 to $3 per month): US carrier fees passed through, not Quo margin.
- International calling and messaging (Per-minute and per-message rates by destination)

Billing notes:

- Annual billing saves roughly 20 to 26 percent depending on tier: $48 a year on Starter, $120 on Business, $144 on Scale.
- There is no seat minimum. One person can buy one seat, which is genuinely rare in business phone and the reason solo operators pick Quo over Aircall or CloudTalk.
- Unlimited calling covers US and Canadian numbers only. Calls and texts to anywhere else are metered per destination, so an outbound team working EMEA should price the traffic before committing.
- US A2P 10DLC registration is mandatory for business texting and carries carrier fees on top of the seat price. Budget a one-time charge plus a few dollars a month per campaign.
- Sona credits are the one place the bill can move unexpectedly. A busy after-hours agent on the free 1,000-credit allowance will hit a bundle upgrade quickly.
- Cancellation is self-serve in the app with no penalty, and the seven-day trial does not require a sales conversation.

Value assessment: At $23 a seat for recording, transcripts, AI summaries, and CRM write-back, Business is the best price-to-capability ratio in small-business phone, and the fact that a number is included rather than billed separately quietly saves another few dollars a seat against Aircall or CloudTalk. The value case collapses only in two places: heavy international traffic, which is metered, and outbound dialing, which does not exist here at all. Judged as a phone system for a company under 30 people, it is underpriced. Judged as a sales dialer, it is not competing.

## Strengths

- The shared-number inbox with internal comments and assignment is the single best small-team phone experience on the market and is why the product spreads by word of mouth.
- A phone number is included in every seat, unlimited US and Canada calling is on the cheapest tier, and there is no seat minimum, so the entry cost is genuinely $15.
- API access on every plan including Starter, which most competitors reserve for their top tier or a custom contract.
- Setup is measured in minutes, not days: pick a number, install apps, invite the team. No PBX concepts, no dial plans, no reseller.
- Sona gives a two-person company a plausible after-hours front desk without hiring anyone, and it is bundled rather than sold as a separate SKU.
- Voicemail transcription on the free-entry tier and automatic recording plus AI summaries at $23 are cheap for what they replace.
- Well capitalized after $105M in growth financing in September 2025, with a large installed base and a top customer-satisfaction position on review sites.

## Limitations

- No dialer of any kind: no power dialing, no parallel lines, no answering machine detection, no local presence rotation. For a real outbound motion this is disqualifying.
- Unlimited calling stops at the US and Canadian border, and international is metered, which makes cost modelling awkward for anyone selling across regions.
- Call recording, CRM logging, and phone menus are all gated behind the Business tier, so the advertised $15 entry price is not the price most buyers actually pay.
- The Scale tier at $35 mostly buys support and call tags. The value curve flattens hard after Business.
- The rebrand from OpenPhone to Quo in September 2025 fragmented the product's search footprint and documentation trail, and a lot of third-party guides still use the old name.
- Analytics are activity counts, not revenue intelligence. There is no call scoring, no talk-time coaching, and no playbook adherence tracking.
- Compliance is sized for SMBs. There is no advertised regional data residency, and buyers with HIPAA or public-sector requirements should look elsewhere.

## Comparisons

- **Quo (formerly OpenPhone) vs Aircall**: Aircall is the same shape of product one tier up in seriousness: better routing, a real Power Dialer, deeper Salesforce CTI, 250-plus integrations, and a three-license minimum at $30 a seat annually. Quo is cheaper, has no seat minimum, and has a far better shared-inbox and texting experience. Pick Aircall if you have a support or sales team of five or more who need queues and dialing; pick Quo if you are under five people and the phone is a conversation channel rather than a call centre.
- **Quo (formerly OpenPhone) vs CloudTalk**: CloudTalk sells numbers in 160-plus countries, four dialer modes including a ten-line parallel dialer, branded caller ID, and spam remediation, priced from about 19 euros a seat with dialers as paid add-ons. Quo sells a US and Canada phone with a superior messaging experience and no dialer at all. Choose CloudTalk if you are calling internationally or dialing lists; choose Quo if your world is North America and your calls are inbound and relational.
- **Quo (formerly OpenPhone) vs Ringover**: Ringover is a European alternative with numbers in 65-plus countries, a power dialer on its Business tier, and separately priced AI and prospecting modules, but it enforces a three-user minimum with a twelve-month commitment above the entry plan. Quo has no minimum and no commitment. Take Ringover if you need European numbers and a dialer in one vendor; take Quo if you want the cheapest credible North American work number with texting.
- **Quo (formerly OpenPhone) vs JustCall**: JustCall bundles a power dialer at $49, a predictive dialer on SalesPro, and AI coaching at $89, all with a two-seat minimum. Quo has none of that and costs a third as much. If phone is your outbound channel, JustCall is the right family of product; if phone is how customers reach you and you occasionally reach back, Quo does that job better and cheaper.

## Implementation

- Setup time: Under an hour for a solo user and about half a day for a small team. Choose a number, install the apps, set business hours and a ring group, and you are live. Number porting takes longer, typically one to two weeks, and runs in parallel while you use a temporary number.
- Learning curve: Near zero. The interface is a messaging app with a keypad, and staff who have never used a business phone system understand it without training. The only genuinely unfamiliar concept is A2P 10DLC registration, which the product walks you through.
- Onboarding: Fully self-serve on every tier. The Scale plan adds guided onboarding and inbound phone support from Quo, which is worth buying only for teams porting a main business line with complex routing.
- Migration: Porting a US or Canadian number is a standard LOA process and generally completes in one to two weeks. Historical call recordings and message history do not migrate from another vendor, so export anything you need for compliance before you cancel. Coming from a per-DID phone system, expect the bill to drop because numbers are bundled into seats; coming from a dialer, expect to lose functionality you may not have realized you were relying on.

## Platform, API & security

- Platforms: iOS, Android, macOS desktop app, Windows desktop app, Web app, Chrome extension
- API: Public REST API and webhooks included on every plan including Starter, covering calls, messages, contacts, and events. Zapier for no-code automation.
- Compliance: SOC 2, GDPR, A2P 10DLC carrier registration handled in-product, STIR/SHAKEN attestation on outbound US calls
- Data residency: US-hosted. No regional data residency options advertised.
- SSO: Google and Microsoft sign-in on all tiers. Enterprise SAML SSO is not a published feature of the standard plans.
- Security notes: Encryption in transit and at rest, role-based access to numbers and threads, and per-user permissions on shared inboxes. Recording consent handling is the customer's responsibility; on-demand recording exists so two-party consent states can be handled per call.

## Support

- Channels: Email support on all tiers, Live chat on Business and Scale, Inbound phone support on Scale, Priority support on Scale
- Documentation: Help centre covering setup, porting, A2P 10DLC registration, integrations, and the API, plus an active product blog.
- Community: Large informal user base among small businesses and agencies; no large official forum.

## FAQ

### Is Quo the same product as OpenPhone?

Yes. OpenPhone renamed itself Quo in September 2025 alongside a $105M growth financing announcement. It is the same company, the same accounts, and the same product, repositioned from business phone system to what the company calls an AI front office. Existing customers were migrated rather than asked to move.

### How much does Quo cost?

Starter is $15 per user per month billed annually or $19 monthly. Business is $23 annually or $33 monthly. Scale is $35 annually or $47 monthly. Every seat includes a phone number and unlimited calling and messaging to US and Canadian numbers. Extra numbers are $5 a month. There is a seven-day free trial and no seat minimum.

### Does Quo have a power dialer or parallel dialer?

No. Quo has click-to-call and a keypad, but there is no power dialer, no parallel or predictive dialing, no answering machine detection, and no local presence number rotation. If your team dials lists, look at Kixie, PhoneBurner, JustCall, or CloudTalk instead. Quo is a phone system, not a sales dialer.

### What does international calling cost on Quo?

Unlimited calling and messaging applies to US and Canadian numbers only. Everything else is billed per minute for calls and per message for texts at rates that vary by destination. If a meaningful share of your calling is outside North America, model that traffic before you buy, because it is where a cheap seat price stops being cheap.

### Does Quo record calls and transcribe them?

Yes, from the Business tier. You can auto-record every call or record on demand from any device, and recordings are transcribed and summarized by AI. On-demand recording exists partly so teams operating in two-party consent states can record only where consent has been given. Announcing the recording remains the caller's legal responsibility.

### Which CRMs does Quo log into?

HubSpot and Salesforce have native two-way integrations from the Business tier, writing calls, texts, recordings, and AI summaries onto the contact record. A Gong connector exists for teams running conversation intelligence separately, and Zapier plus a public API cover everything else. API access is available on every plan, including Starter.

### What is Sona?

Sona is Quo's autonomous AI agent, launched with the 2025 rebrand. It answers calls and texts when nobody is available, captures lead details, answers routine questions, and hands the conversation back with context attached. Every plan includes 1,000 automation credits a month, and additional credit bundles run from $0 to $199 a month for 1,000 to 60,000 credits.

### Do I have to register for A2P 10DLC to text customers?

Yes, if you are texting US numbers from a business. US carriers require A2P 10DLC registration, and Quo handles it in-product for roughly $19.50 one-time plus a recurring carrier fee of about $1.50 to $3 a month depending on campaign type. These are carrier pass-through costs, not Quo margin, and skipping registration means your messages get filtered.

### Is there a free plan or a seat minimum?

There is no free plan, but there is a seven-day self-serve free trial and no seat minimum at all. A single person can buy a single seat, which is unusual in business phone: Aircall requires three licences, JustCall requires two, and CloudTalk's Expert tier requires three.

### How does Quo handle spam-labelled outbound calls?

Lightly. Quo passes STIR/SHAKEN attestation on outbound US calls, which is the baseline carrier requirement, but it does not sell branded caller ID, a spam remediation service, or a rotating number pool the way CloudTalk, Kixie, PhoneBurner, and Salesfinity do. If your numbers are getting flagged because you dial heavily, that is a signal you have outgrown this product.

## Editorial verdict

Quo is the best small-business phone system you can buy for the money, and it is not an outbound sales tool. The shared-number inbox, the included number in every seat, the absence of a seat minimum, and API access on the cheapest plan add up to a product that a two-person company can adopt in an afternoon and never think about again. Business at $23 with recording, transcripts, AI summaries, and HubSpot or Salesforce write-back is the tier to buy. What you do not get is any dialer, any local presence rotation, any spam remediation, or unlimited calling beyond North America, and those absences are the whole difference between this category's phone systems and its dialers. If your reps work lists, buy Kixie or PhoneBurner. If customers call you and you call them back, buy Quo and stop shopping.
