Quo Pricing 2026 (Formerly OpenPhone): Every Plan and Fee
Quo, the business phone app formerly called OpenPhone, prints its plan prices plainly. The bill is harder to predict, because AI calls, texting registration, extra numbers and telecom taxes all sit outside the per-user price. Every number below is checked against Quo’s pricing page and help center (September 2026).
The quick answer: Quo costs $19, $33 or $47 per user per month on monthly billing (Starter, Business, Scale), or $15, $23 or $35 billed annually. Every workspace gets about 10 Sona AI calls a month, and more cost $25 to $199 a month in credit tiers. Budget $19.50 once plus $1.50 to $3 a month for texting registration, $5 a month per extra number, and state telecom taxes. Want an AI that answers every call and books callers on your real calendar instead of taking a message? That’s Carly, and setup is one prompt in ChatGPT or Claude.

What each Quo plan unlocks
Starter: $19 monthly, $15 annually
A number per user, US and Canada calling and texting, voicemail transcripts, the Quo API, Sona, the ChatGPT and Claude connection, and email ticket support. Shared numbers are capped at 10 paid users, call recording is manual, and AI call summaries and transcripts only cover calls Sona handled.
Best for: a solo operator or a small crew that mostly calls and texts back. Watch out for: phone menus, ring orders, call transfers and HubSpot or Salesforce sync all start on Business.
Business: $33 monthly, $23 annually
Quo’s most popular plan. It adds AI call summaries and transcripts on every call, group calling, custom ring orders, call transfers, phone menus (IVR), analytics, automatic call recording, HubSpot and Salesforce integrations, and live chat support. Quo’s help center lists Business and Scale as HIPAA-ready, and shared numbers lose the 10-user cap.
Best for: teams of 2 to 20 sharing a main line. Watch out for: monthly billing costs $10 a user a month more than annual, $600 a year extra for a 5-person team. Want callers booked rather than summarized? Carly books them during the call.
Scale: $47 monthly, $35 annually
Adds AI call tags, dedicated onboarding, priority live chat and email support, and inbound phone support (weekdays, 8 AM to 5 PM Pacific). Everything else matches Business.
Best for: larger teams that want a person on the phone when something breaks. Watch out for: the $12 a user a month over Business (annual) mostly buys support, onboarding and AI call tags, not new calling features.
Sona AI agent pricing: credits, tiers and overages
Sona is Quo’s AI voice agent. It answers calls around the clock, answers questions from a knowledge base you write, takes messages, runs “jobs” you define, texts a link mid-call and transfers callers to a teammate. It’s on every plan, but it’s metered: 100 credits per call, with 1,000 credits a month (about 10 calls) included.
That allowance is per workspace, not per user. A 10-person team gets the same 10 Sona calls as a solo plumber.
| Sona tier | Price | Calls included | Effective cost per call | Overage per call |
|---|---|---|---|---|
| Tier 1 | $0 | 10 | n/a | $1.00 |
| Tier 2 | $25/mo | 40 | $0.63 | $0.75 |
| Tier 3 | $49/mo | 100 | $0.49 | $0.65 |
| Tier 4 | $99/mo | 250 | $0.40 | $0.55 |
| Tier 5 | $199/mo | 600 | $0.33 | $0.45 |
The rules in Quo’s Sona billing docs:
- Calls under 15 seconds don’t count.
- Overages are off by default. Out of credits, Sona stops answering and calls fall to your fallback path, usually voicemail. With overages on, it keeps going at your tier’s rate.
- Credits expire monthly, with no rollover, even on annual plans.
- Upgrading mid-month re-rates the whole month at the new tier.
- Paid tiers need a paid plan billed online, so not during the trial or through Apple.
Which tier is actually cheapest, with overages switched on:
| Sona calls per month | Cheapest option |
|---|---|
| Up to 35 | Tier 1 plus $1.00 overages |
| 36 to 72 | Tier 2 ($25) |
| 73 to 176 | Tier 3 ($49) |
| 177 to 431 | Tier 4 ($99) |
| 432 and up | Tier 5 ($199) |
A tier only pays off once you’re well past the calls it includes. At 30 calls a month, $20 of overages beats Tier 2’s $25.
Sona’s text-lead capture is in beta, included on every plan for now with pricing to follow, and trained separately from Sona for calls.
On appointments, Quo’s own job guide has Sona collect the caller’s details and text a booking link. Carly books the caller on your team’s real Google or Outlook calendar while they’re still on the line.
Add-on costs the plan cards don’t show
Extra phone numbers: $5 a month each
Each user comes with one number. Every number beyond your user count, local or toll-free, is $5 a month on any plan. Porting a number in costs nothing from Quo, though your old carrier may charge.
Texting registration: $19.50 once, then $1.50 to $3 a month
US carriers require anyone texting from a local virtual number to register with The Campaign Registry (A2P 10DLC). Quo passes the fees through:
| Registration type | One-time | Monthly | Notes |
|---|---|---|---|
| Business with an EIN | $19.50 | $1.50 | Every number in the workspace can text |
| Nonprofit | $19.50 | $3.00 | Same business registration path |
| Sole proprietor (no EIN) | $19.50 | $2.00 | One number cleared to text, possible daily cap |
| Resubmission after rejection | $15 | Charged each time | |
| Toll-free verification | Included | Included | Each toll-free number registered separately |
Timing matters more than the fee. Quo says most approvals land in 24 to 48 hours, some sit pending for up to 20 days, and you can’t text US numbers while you wait. Register the day you sign up, especially if you plan on SMS appointment booking.
Automated texts: $0.01 per segment
Texts sent through the Quo API, Zapier, Make or Clay draw $0.01 per US or Canadian segment from a prepaid balance, though the same text sent from the app is included. At a zero balance, automated texts fail.
International calls and texts
The US and Canada are included. Everything else is billed per minute or per message from prepaid credits. Rates vary by carrier within each country: on Quo’s rate table, Australia runs $0.05 to $0.33 a minute and $0.11 a text, India $0.07 to $0.09 a minute and $0.11 a text, and Germany $0.03 to $0.48 a minute.
Telecom taxes and regulatory fees
Quo’s prices exclude taxes. It collects telecom taxes and surcharges for billing addresses in 16 states, including California, Florida, New York, Pennsylvania and Washington. Expect some mix of 911 surcharges, state and federal Universal Service Fund fees (the federal rate changes quarterly), local utility taxes and a relay service fee. Your first invoice is the only reliable number.
What Quo actually costs: 1, 5 and 10-person teams
Every example is before telecom taxes, and each business registers for texting with an EIN.
| Team | Plan | Per month, annual billing | Per month, monthly billing |
|---|---|---|---|
| Solo | Starter | $36.50 | $40.50 |
| 5 people | Business | $175.50 | $225.50 |
| 10 people | Business | $345.50 | $445.50 |
| 10 people | Scale | $465.50 | $585.50 |
Solo contractor on Starter
A one-person remodeling business with Sona on after-hours calls, about 30 a month.
- Starter, annual: $15 a month ($180 upfront)
- Texting registration: $1.50 a month, plus $19.50 once
- Sona: Tier 1 with overages on, 20 calls over at $1.00 = $20 a month
- Total: $36.50 a month, $457.50 in year one. On monthly billing, $40.50 a month.
5-person property management office on Business
Five staff with direct numbers, plus a main line and a maintenance line. Sona covers overflow and after-hours, about 90 calls a month.
- Business, annual: 5 × $23 = $115 a month ($1,380 upfront)
- Extra numbers: 2 × $5 = $10 a month
- Texting registration: $1.50 a month, plus $19.50 once
- Sona: Tier 3 = $49 a month
- Total: $175.50 a month, $2,125.50 in year one. On monthly billing, $225.50 a month.
The real cost per seat is $35.10, about 53% above the $23 sticker price.
10-person home services company: Business or Scale
Ten staff, three location lines, and Sona handling about 220 calls a month. Both plans carry the same extras: $15 for numbers, $1.50 for registration and $99 for Sona Tier 4, so $115.50 a month on top of seats.
- Business: $230 in seats, $345.50 all in on annual billing ($4,165.50 in year one)
- Scale: $350 in seats, $465.50 all in on annual billing ($5,605.50 in year one)
If most of those 220 calls are prospects asking for an appointment, the real question is what the AI does with them. Carly books them on the call.
Trial, plan changes and cancellation terms
- 7-day trial with every feature unlocked, then features drop to your plan’s level. A credit card is required, and international calling is off.
- Upgrades apply immediately, prorated. Downgrades wait for renewal.
- No refunds on payments already made. Cancel from settings in a few clicks and service runs to the end of the billing period.
- Numbers after canceling: Quo’s help center says 30 days, its pricing page FAQ says 60. Port out before you cancel rather than rely on either.
The complaints that come up most in Quo reviews: slow ticket-based support during outages or billing problems, Sona costs climbing once it becomes the main answering layer, and texting blocked while registration is pending. More in our Quo review and Quo alternatives.
Where Carly fits: an AI line that books the caller
Quo is a solid, well-priced phone app for teams that answer most calls themselves. Carly is for the calls nobody picks up. It follows your rules exactly, the same way on every call.
- Answers your line 24/7, or only when your team doesn’t pick up. Spanish speakers get answered in Spanish.
- Books the caller on your team’s real Google and Outlook calendars during the call, round robin.
- Calls new web leads within about a minute of a form fill, then texts and emails if they miss it.
- Texts and WhatsApp from the same number: two-way texts and WhatsApp messages, a text back on every missed call, reminders to a list, group texts.
- Hands callers to a person through ring groups or a phone menu.
- Logs everything to one team inbox and your CRM: HubSpot, Salesforce, Dynamics 365 or Carly’s own CRM.
- Runs from ChatGPT or Claude. Build the agents from a chat, place calls, watch a live call and steer it.
- Plugs into the rest of your stack. Carly connects to thousands of apps, and every call can trigger free Zapier-style workflows.
Copy one prompt into ChatGPT or Claude, grab a number, and you’re live.
Carly business setup prompt
Paste this into ChatGPT, Claude or any AI. It walks you through the rest.
Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.
# Connect Carly Teams to an AI app
> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.
MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)
## Setup
Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.
1. Add Carly Teams:
- ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
- Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
- Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
- Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
- Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
- Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
- Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
- Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
- Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
- Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
Sign in with the Carly account that belongs to the organization.
2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.
3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.
4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.
## Email, calendars and workflows
Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.Pricing: Free Zapier-style workflows; AI agents from $35/month. Get started, or book a call if you’d like a walkthrough.
Stay on Quo if your team places most calls and texts itself and Sona covers a few dozen overflow calls a month. Pick Carly if missed calls are lost bookings or your team lives in HubSpot, Salesforce or Dynamics 365.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
