Quo (formerly OpenPhone) is a $15/user/month-billed-annually business phone app whose Sona AI agent is included on every plan — about 10 AI calls free monthly, then flat credit tiers of $25 to $199 as volume grows.
You are a US or Canadian solo who wants one simple app for your number, texts and after-hours AI answering, with predictable step pricing.
You need the agent to confirm calendar bookings itself, answer on a phone system you already own, or handle heavy call volume in many languages.
Workflows are built only from verified capabilities in our listing research — no vendor copy, nothing invented.

One new or ported local or toll-free number per user is included; extra numbers are $5/month.
Set Sona to answer when you miss a call or outside business hours, and give it your FAQs and the caller details to collect.
US messaging needs the $19.50 one-time carrier registration; watch the 1,000 included credits (about 10 calls) before choosing a Sona tier.

Two meters, both published on one page. (1) Phone plan, per user: Starter $15/month billed annually ($19 monthly), Business $23 ($33 monthly), Scale $35 ($47 monthly). (2) Sona AI agent, metered in automation credits at 100 credits per AI-handled call: every plan includes 1,000 credits (about 10 calls) free; paid tiers are $25/month for 4,000 credits (about 40 calls), $49 for 10,000 (about 100), $99 for 25,000 (about 250) and $199 for 60,000 (about 600), with overage per call from $1.00 down to $0.45 by tier.

|---|---|---|---|---|
| StarterSolo pick | $15/user/month billed annually at $180 ($19 billed monthly) | $15/mo | Per seat / month | AI summaries and transcripts cover Sona-handled calls only on Starter · Call transfers and phone menus sit on Business |
| Business | $23/user/month billed annually at $276 ($33 billed monthly) | $23/mo | Per seat / month | Sona credit tiers are billed on top of the seat price |
| Scale | $35/user/month billed annually at $420 ($47 billed monthly) | $35/mo | Per seat / month | Support and tagging tier — no extra Sona credits over the other plans |
Sona call count, in steps: the included allowance is only about 10 calls, so most working businesses land on the $25 or $49 credit tier — predictable steps rather than a per-minute meter, and overages are off by default, but the tier is billed on top of every seat.
Price record · 2026-11-05: First listing check, 2026-11-05, on quo.com/pricing — read in full this run with BOTH billing states extracted: monthly Starter $19, Business $33, Scale $47 per user; annual Starter $15 ($180/year), Business $23 ($276), Scale $35 ($420). The Sona credit table extracted on the same page in both states: Tier 1 $0 with 1,000 credits (10 calls) included on every plan, Tier 2 $25 / 4,000 (40 calls), Tier 3 $49 / 10,000 (100), Tier 4 $99 / 25,000 (250), Tier 5 $199 / 60,000 (600); overage $1.00, $0.75, $0.65, $0.55, $0.45 per call. Add-ons extracted from the same page: extra numbers $5/month billed annually, carrier review $19.50 one-time plus $1.50–$3/month messaging fee, automated SMS $0.01/text. Note the vendor's own pricing-guide blog states Tier 2 as '50 calls' in one sentence while its own table on the same page and the pricing page state 40 calls for 4,000 credits; this listing follows the pricing page table (40).

Quo is the company formerly known as OpenPhone, and the rebrand matters for a buyer because older reviews and prices sit under the old name: the product, plans and entity carried over. What Quo sells a solo founder is the simplest version of this job — a clean business number for calls and texts in the US and Canada, in a shared inbox on phone and desktop, with an AI agent, Sona, now included on every plan rather than sold as a separate product. The seat prices are the lowest in this batch: Starter is $15 per user a month billed annually ($19 monthly), Business is $23 ($33 monthly) and Scale is $35 ($47 monthly), each with one new or ported number per user. Sona's meter is the part to understand: every plan includes 1,000 automation credits a month, one AI-handled call costs 100 credits, so the included allowance is about ten calls. Past that, Sona is sold in credit tiers — $25 a month for about 40 calls, $49 for about 100, $99 for about 250 and $199 for about 600 — with per-call overage from $1.00 on the free tier down to $0.45 on the top tier, and overages off by default so a busy month sends callers to your fallback instead of quietly billing you. Sona answers from the business details and FAQs you give it, collects caller information, transfers to a teammate and can text a scheduling link during the call — note that it texts the link rather than confirming a calendar slot itself. The feature ladder is real: AI summaries and transcripts for all calls, call transfers, phone menus and HubSpot or Salesforce integrations all sit on Business, not Starter, where summaries cover Sona-handled calls only.
Solo Fit stays the public score: the qualitative roll-up of these four published inputs under the How We Rank method. Quo is fully no-code and Sona is a step in a call flow rather than a project; clarity is strong because both meters are published on one page, held back only by the credit unit needing conversion into calls.
The difference: JustCall is the CRM-and-dialer phone system with a two-seat minimum and a $0.99/minute AI add-on; Quo is the lighter app whose agent is included in small monthly credit allowances.
The difference: CloudTalk covers numbers in 160+ countries and sells its receptionist in 200-minute bundles from $99; Quo is US/Canada only but starts at $15 all-in for light AI use.
The difference: Upfirst is a standalone answering agent you point your existing number at; Quo replaces your phone app entirely and Sona only works inside it.
Yes — OpenPhone rebranded to Quo in September 2025, per the vendor's own pricing guide. The plans and prices carried over, the site is now quo.com, and Sona is the AI agent launched with the rebrand. Older reviews under the OpenPhone name describe the same product.
One Starter seat is $15/month billed annually ($19 billed monthly), checked on quo.com/pricing on 2026-11-05, and it already includes Sona for about 10 AI calls a month. At about 100 AI calls a month the all-in figure is $64/month: the $15 seat plus Sona Tier 3 at $49.
One AI-handled call uses 100 automation credits. Every plan includes 1,000 credits a month (about 10 calls); paid tiers buy 4,000 credits for $25, 10,000 for $49, 25,000 for $99 or 60,000 for $199 a month, with per-call overage from $1.00 on the included tier down to $0.45 on the top tier, per the pricing page table checked on 2026-11-05.
Not directly. On the vendor's own description, Sona texts the caller a scheduling link during the call and the caller completes the booking through it. If you need an agent that confirms a slot in your calendar on the call itself, compare the calendar-booking tools in this job instead.
Yes, three published ones on the pricing page: US texting registration costs $19.50 one-time plus $1.50–$3/month in messaging fees, extra phone numbers are $5/month each billed annually, and automated SMS sent via the API, Zapier or Make costs $0.01 per outgoing text.
