Call reliability is the recurring complaint — G2 logs hundreds of connection and disconnection reports, and calls get shaky the moment you're off Wi-Fi. Throughout this review we weigh it against RingCentral.

✓ Pricing re-verified 31 Aug 2026
(2026) Three tiers: Starter $15/user/mo annual (billed $180/yr) or $19 monthly; Business $23 annual ($276/yr) or $33 monthly; Scale $35 annual ($420/yr) or $47 monthly. 7-day free trial. Taxes and fees are added at checkout and are not quantified on the page. Itemised extras: The Campaign Registry takes $19.50 once plus $1.50-$3/month to keep US carrier messaging deliverable, each additional phone number is $5/month, and international calling is billed per minute.
The Sona AI answering agent is included on every plan with 1,000 automation credits a month (a call costs 100 credits, so ten calls); more credits run $25/mo for 4,000 up to $199/mo for 60,000, with per-call overage falling from $1.00 to $0.45 across those tiers. Plans change — always verify the live price on their site.

There's also no video conferencing, no 24/7 support on lower tiers, international calling costs extra, and the CRM integrations are shallow (the HubSpot app scores ~3.3/5).
Shared business numbers, texting and AI call summaries for small teams, formerly OpenPhone. About $15/user/month on annual billing, plus telecom taxes and surcharges in 16 US states. Call reliability off Wi-Fi is the recurring complaint, and there is no video conferencing.

Recurring themes from the buyer-review sites listed at the foot of this page, read in August 2026. We have not run Quo ourselves, so this is other buyers' experience rather than ours. We summarise it here because the complaints are usually the part a vendor page leaves out.
There are three tiers now, not two. Starter is $15 per user a month on annual billing and $19 monthly. Business is $23 annual and $33 monthly. Scale, which is new, is $35 annual and $47 monthly. The monthly premium is uneven — 27% on Starter, 43% on Business and 34% on Scale — so the middle plan, the one most teams land on, is the one that punishes monthly billing hardest, and nothing on the page frames it that way.
Then there is everything that is not the sticker. The page says only that applicable taxes and fees are added at checkout, without quantifying them, so a five-person team can price the $75 subscription and nothing else. What is itemised sits lower down: The Campaign Registry takes $19.50 once and $1.50 to $3 a month to keep messaging deliverable to AT&T, T-Mobile and Verizon, every extra phone number is $5 a month, and international calling is per-minute on top.
Budget above the sticker and ask for your own tax rate in writing, because there is no way to see it before you buy. The AI agent is the newest meter. Sona answers calls around the clock and is now included on every plan, but it runs on credits: 1,000 automation credits a month, and a call costs 100. That is ten answered calls a month before you are buying more — $25 a month for forty calls, up to $199 for six hundred, with overage from $1.00 down to $0.45 a call.
For a phone system whose whole promise is not missing calls, ten a month is a trial allowance rather than a feature. What that money is buying is where this gets harder to recommend. Call reliability is the recurring complaint rather than an isolated one — G2 carries hundreds of connection and disconnection reports, and calls get shaky the moment you leave Wi-Fi. For a phone system that is not a feature gap, it is the product.
There is also no video conferencing, no 24/7 support on the lower tiers, and the CRM integrations are shallow — the HubSpot app sits at about 3.3 out of 5. So make the reliability question the whole evaluation and let price come second. If calls hold up on your network, in your building, on the connections your team actually uses, Starter on annual billing is a reasonable price for a business line. If they do not, no tier fixes it.
Our monthly capture read this vendor's pricing page in July 2026 and again in August 2026, and the amounts were the same both times. We keep watching — the registry records what moves.
Test call reliability first, and test it badly on purpose. So use the 7-day free trial to make calls from a phone on mobile data, from the building your team actually works in, at the time of day they actually call. Add up the fees that sit outside the sticker before you compare it with anything. The page quantifies none of the taxes — it says only that they are added at checkout — but it does itemise $19.50 once and $1.50 to $3 a month for Campaign Registry messaging registration, $5 a month for every phone number beyond the one per user, and per-minute international calling.
Ask for your own tax rate in writing. Then check the Sona allowance against your actual call volume. Every plan includes 1,000 automation credits a month and an answered call costs 100, so the included allowance is ten calls. If the AI answering is the reason you are buying, price the $25-to-$199 credit tiers in from the start rather than discovering them later. Check the CRM integration on your own CRM rather than on the logo list — the HubSpot app sits at about 3.3 out of 5 — and be clear about what no tier adds: no video conferencing, and no 24/7 support on the lower plans.
Distilled from Read 31 Aug 2026 through our own European server, because quo.com refuses TLS to our usual client: quo.com/pricing — the three plan cards in both the monthly and the annual state (with 'Billed annually at $180/$276/$420' and the matching $48/$120/$144 yearly savings), the Sona credit table (tiers at $0, $25, $49, $99 and $199 a month for 1,000 to 60,000 credits, with per-call overage from $1.00 to $0.45), the 'All prices in USD / Applicable taxes and fees added at checkout' line, and the compare-plans rows for Campaign Registry fees ($19.50 one-time, $1.50-$3/month) and additional phone numbers ($5/month each). Note: quo.com/llms.txt returns a 404.
Both columns come from the same place: each vendor’s own published pricing, read on the date shown in the sources at the foot of this page. We do not average them into a score.
Both names above are affiliate links: we may earn a commission if you sign up, at no extra cost to you. Neither changes what this table says: both columns come straight from the vendors’ own pricing pages.
The natural comparison is RingCentral or Aircall — the fuller, more reliable but pricier phone systems. Weigh it against RingCentral on the job you actually need done.
Everything we publish about Quo links back here — the review stays the honest hub:
The ex-banker filter — the same yardstick on every review (how we review): My ex-banker filter is simple: does Quo remove a real cost — time, errors, missed revenue — bigger than what it charges?
Generally yes, since this category is built for it, but the details that bite are timezone handling, how per-seat cost scales as the team spreads, and whether numbers, routing or coverage exist in the countries your people actually sit in. Availability varies far more by country than the marketing pages suggest, so check your specific regions before committing.
