Quo Review

Reviewed by Tom · Founder & lead reviewer

What you get

Quo is a business phone line that lives in an app instead of on a desk. You get a real phone number - or you port your existing one - and calls, texts, voicemails, and contacts for that number sit in one shared workspace the whole team can see. The point of difference against a personal mobile is that a number is not owned by one person: an installer, an office manager, and the owner can all watch the same line, and nothing is lost when someone is on site. Quo's own site puts the user base at more than 90,000 businesses and names home services, property management, law firms, healthcare, and sales teams as its core markets. Layered on top is Sona, an AI voice agent that picks up when nobody is free and captures who called and what they wanted.

What the rebrand changed, and what it did not

If you have been looking at this product for a while, you know it as OpenPhone. The company announced the change to Quo on 23 September 2025, alongside $105 million in growth financing - $96 million from General Catalyst's Customer Value Fund plus $9 million in equity from existing investors - and the launch of Sona. It is worth being clear about what a rename of this kind does and does not mean, because search results for the old name and the new name still disagree with each other. The product, the apps, the numbers, and the API carried over; existing accounts were not migrated or reset. What changed is positioning: the pitch is no longer 'a better business phone' but an AI front office. That matters for how you should read the pricing, because the AI is the part that is metered.

Where it wins

Ease of use is the strongest pillar and the one reviewers return to most. G2 carries 3,394 reviews at 4.7 out of 5, and Capterra's ease-of-use sub-score sits at 4.3. The consistent story is that a small team can have a working shared business line the same day, without a phone system, a handset, or an IT contractor. That is not a small thing for a five-person company where the alternative is an owner's personal mobile and a spreadsheet of missed calls. The second win is scope on the entry plan. Starter at $15 per user per month on annual billing - $19 if you pay monthly - includes one number, US and Canada calling and messaging, voicemail transcripts, Sona, and 1,000 automation credits. Plenty of competitors hold the AI back for the top tier; Quo does not.

What the pricing actually costs you

Three plans, priced per user. Starter is $15 annual / $19 monthly. Business is $23 annual / $33 monthly and adds AI call summaries and transcripts, group calling, call transfers, HubSpot and Salesforce integrations, phone menus, automatic call recording, and live chat support. Scale is $35 annual / $47 monthly and adds AI call tags, dedicated onboarding, priority support, and inbound phone support. Add-ons are where the bill moves. Extra numbers are $5 a month each. Automated SMS sent through the API, Zapier, or Make is $0.01 per message. And Sona runs on credits: tiers from $0 to $199 a month buy 1,000 to 60,000 credits, at 100 credits per call. Do that arithmetic before you budget. The 1,000 credits bundled with Starter cover roughly ten answered calls a month - a demo allowance, not a service. At the other end, $199 for 60,000 credits is about 600 calls, or 33 cents a call, which is defensible if those calls are booked jobs and expensive if they are wrong numbers. Note also that Starter caps a shared number at 10 users; Business and Scale lift that. The free trial is 7 days, which is tight for a decision that involves porting a number.

Where it gives ground

Two areas pull the score down, and both are worth taking seriously because they concern the part of the product that has to work every single time. The first is reliability. Verified Capterra reviews - a smaller sample, 64 reviews at an overall 4.2 - repeatedly describe dropped calls, contacts failing to sync, scheduled messages not sending, and missed-call notifications that do not appear until the app is refreshed by hand. One reviewer's complaint goes to the root of the product: that calls could not actually be answered because they disconnected automatically. The second is support. Capterra's customer-service sub-score is 4.1, and the recurring pattern in the negative reviews is not rudeness but slowness at exactly the wrong moment. The plan structure compounds this: live chat begins at Business and inbound phone support only at Scale, so the cheapest plan - the one a small firm is most likely to start on - is also the one with the thinnest safety net when a line goes down.

The gap between the two review sites is the interesting number

Quo shows 4.7 stars across more than 3,400 reviews, and G2 agrees. Capterra shows 4.2 across 64. Both are real; they are measuring different populations, and neither is the truth on its own. A very large, very positive sample usually means the ordinary case works well and people are happy to say so. A much smaller sample landing half a point lower, with reliability as the theme, usually means the failure mode is uncommon but bad when it lands. That is a reasonable model of this product: for most small teams it does what it says, and for a minority it breaks in the one way a phone line must not. Our advice follows from that shape rather than from either average. Port a number only after you have run a second, spare number on the platform through a normal week.

The API ceiling, if you plan to report on calls

This site exists for people who want to hold spend accountable to outcomes, so this deserves its own note. Quo's webhook API does not give access to messages, and reviewers describe the contact API as still rough. If the plan is to pull call and text data into a dashboard next to your ad spend and work out a real cost per booked job, check that path before you commit, not after. The in-app analytics are adequate for seeing call volume and response time; they are not a substitute for having the raw events. For the same reason, the customisation ceiling is real - Quo is deliberately simple, so complex routing rules and conditional call logic are not what it is for.

Who should skip it

Larger organisations with real telephony requirements - multi-level IVR trees, compliance recording rules, contact-centre queueing, or an existing PBX to integrate with - will hit the ceiling quickly and should look at a platform built for that. Anyone whose business depends on custom call workflows should also look elsewhere. And if you are in a place with unreliable internet, remember the whole thing is an app over a data connection; there is no copper line underneath it.

How we scored it

Ease of use 4.3 - fast to a working line, held back slightly by carrier registration and porting friction that reviewers describe as slower than advertised. Features 4.0 - strong shared-inbox core and a genuinely useful AI agent, marked down for the API limits and the lack of custom call logic. Value 4.1 - the headline price is honestly low, but the Sona credit meter and $5 extra numbers mean the number on the pricing page is not the number on the invoice. Support 3.7 - the lowest pillar, because the cheapest plan gets the least help and slow responses are the most repeated complaint in verified reviews. All figures here were read at quo.com and the review platforms on 16 September 2026; phone pricing moves, so check the current page before you buy.

Best for

Small teams that lose money to unanswered calls and want one shared number, texting, and an AI answering service without running a phone system.
