OpenPhone Sona cost vs an owned receptionist (2026)
OpenPhone Sona cost is $25–$199/mo after 10 free calls. 250 calls run $99/mo versus an $8,000 one-time receptionist you own, no subscription.
A 150-call month blows past Quo’s included Sona pack on week one. According to Quo’s Sona pricing docs, every workspace gets 1,000 credits — about 10 AI-answered calls — and unused credits expire when the billing period ends. OpenPhone Sona cost is not the $15 seat. It is the credit meter that starts the day the phone actually rings.
Short answer: OpenPhone Sona cost is $25, $49, $99, or $199 per month in AI credits after 10 included calls, on top of Quo (formerly OpenPhone) seats, with $0.45–$1.00 overages if you enable them. An owned AI Receptionist is $8,000 once, no subscription to me, then your carrier and model bills. Keep Sona while you test inside Quo. Own the line when the script, CRM note, and number should survive if you cancel the phone app.
I am not telling you to rip out OpenPhone. The shared inbox is a good phone system. The question is whether Sona’s credit packs are the receptionist, or a trial that dumps to voicemail when the pack runs out.
How much is OpenPhone Sona cost at real call volume?
OpenPhone Sona cost is a monthly credit pack: about 10 free AI-answered calls, then $25 / $49 / $99 / $199 for roughly 40, 100, 250, or 600 calls, billed on top of per-user Quo seats. Calls under 15 seconds do not count. Credits do not roll over.
Quo’s own 2026 pricing guide lists seats at $15, $23, and $35 per user per month on annual billing (Starter, Business, Scale). Extra numbers are $5/month. Sona is the add-on.
| Sona tier | Monthly | Included AI calls | Overage / call |
|---|---|---|---|
| Free (all plans) | $0 | ~10 | $1.00 if overages on |
| Tier 2 | $25 | ~40 | $0.75 |
| Tier 3 | $49 | ~100 | $0.65 |
| Tier 4 | $99 | ~250 | $0.55 |
| Tier 5 | $199 | ~600 | $0.45 |
Those call counts come from Quo’s published 100 credits per call. Overages are off by default. When the pack hits zero, Sona stops and follows the fallback in your call flow — which is how a “24/7 AI receptionist” becomes voicemail on a busy Thursday.
The OpenPhone AI receptionist product page is honest about two limits I care about: Sona currently answers inbound calls only, and it runs inside Quo, not as an agent you take with you.
Is Sona cheaper than an owned receptionist over 24 months?
Sona is cheaper on cash in year one and usually in year two. The $8,000 owned build is a 36-month and ownership decision, not a sticker-price win against a $99 credit pack. Do not pretend otherwise.
| Cost item | Sona credits only | Owned AI receptionist |
|---|---|---|
| Light shop (~100 calls) | $49/mo → $1,176 / 24 mo | $8,000 once |
| Busy line (~250 calls) | $99/mo → $2,376 / 24 mo | $8,000 once |
| Heavy line (~600 calls) | $199/mo → $4,776 / 24 mo, $7,164 / 36 mo | $8,000 once |
| Meter | Credits expire monthly; overages $0.45–$1.00 | Your Twilio/carrier + model usage |
| Who keeps the agent | Quo account | Your accounts |
Add seats if you are modeling the whole phone bill. Three Business users at $23 is $69/month before Sona. Five users plus the $199 pack is $314/month — $7,536 over 24 months and $11,304 over 36 — and that still rents the voice agent.
Full SaaS-versus-owned math lives on AI receptionist pricing. Plug real call count into the subscription vs own calculator. Sona is one of the cheaper meters; I walked the same shape on Rosie AI receptionist cost. Own the line when the phone is the leak and you do not want the prompt in a vendor you might leave.
What does the workflow actually look like?
Trigger is an inbound ring in Quo. Sona talks, logs the call, and optionally writes a CRM record. You only get pulled when the script says so — or when credits run out. If that chain breaks, you bought a nicer voicemail.
| Step | Sona on Quo | What I would ship owned |
|---|---|---|
| Trigger | Inbound call in the Quo flow, 24/7 | Missed, overflow, after-hours, or direct |
| AI action | Answers FAQs, takes a message, can transfer, can text | Same, plus your exact emergency vs quote vs intake rules |
| System of record | Quo inbox; HubSpot, Salesforce, Pipedrive, or Jobber when connected | Jobber, Housecall Pro, Clio, Google Calendar, GlossGenius, or a sheet |
| Human escalation | Transfer inside Quo | SMS/call to the owner with the note already written |
Call +1 (832) 861-0469 right now — the receptionist that answers is the exact deployment I’m describing.
For a solo attorney on Clio, the note is name, matter type, deadline, and a conflict flag — not legal advice. For a 4-truck HVAC shop on Jobber, Quo’s connector can create a request during the call if you write that intent. For a salon on GlossGenius, Sona’s listed CRM set is not the book.
If after-hours text-back is the leak, not the voice pack, use the text answering service.
What would I automate first?
After-hours and missed-call capture first. CRM write second. Replacing every seat last. Owners fail when they turn Sona on all day, enable overages, and never watch the credit reset date.
Use this before you buy a pack or an $8,000 build:
| Question | If yes | If no |
|---|---|---|
| Under ~40 real AI-answered calls a month? | Stay on free or $25 Sona | Price Tier 3+ or owned |
| Already live in the Quo inbox every hour? | Sona is the native add-on | Do not add a second dashboard |
| Must the job land in Jobber/HubSpot during the call? | Configure Sona’s Jobber/HubSpot write | Do not call it booked |
| Book is Housecall Pro, GlossGenius, or custom Clio fields? | Prefer owned write | Quo’s list may be enough |
| Credits hit zero before month-end? | Raise the pack or own the line | Keep overages off so you see the cap |
| Need outbound follow-up calls, not just inbound? | Sona is inbound-only — different tool | Inbound overflow is enough |
If the leak is the public site, not the phone, fix custom web development before you buy any receptionist.
When this isn’t the right move yet
Do not pay $8,000 to replace a $25 Sona pack you have not measured. Watch one billing cycle of real AI-answered calls, with overages off, before you change anything.
Wait on an owned build if you are under ~40 meaningful inbound calls a month, the team already works the Quo inbox, Jobber or HubSpot logging is enough, callers need judgment on the first ring, or nobody will answer an escalation text at 9pm.
Skip Sona as the long-term receptionist if you refuse a credit that expires, you need outbound calls, you need a CRM Quo does not list, or you want the agent to keep running when you leave OpenPhone/Quo.
What is the next step?
If OpenPhone Sona cost is the tab you have open, count last month’s inbound rings that a human did not take. Ten included calls is a trial. $99 is a busy line. $8,000 is the same job in accounts you own.
My AI Receptionist is $8,000 once. For a law-office shaped practice, the deployment looks like the attorney receptionist build: after-hours capture, intake facts, Clio or a sheet, owner on exceptions.
If that is your situation, send the free audit. It is a short form. I reply with your AI replacement map within 24 hours, including whether I would keep Sona, raise the credit pack, or build the owned line.
FAQ
How much is OpenPhone Sona cost per month? +
OpenPhone Sona cost is a credit pack on top of your Quo (formerly OpenPhone) seats. Every plan includes about 10 AI-answered calls. Paid tiers are $25 for ~40 calls, $49 for ~100, $99 for ~250, and $199 for ~600, per Quo's Sona pricing docs. Unused credits expire. Overages run $0.45–$1.00 per call if you turn them on.
Is Sona cheaper than an owned AI receptionist? +
Yes in year one. Sona at $99/month is $2,376 over 24 months. My AI Receptionist is $8,000 once, then your carrier and model usage, with no monthly fee to me. Sona wins at light volume inside Quo. Own it when the script, number, and CRM write should survive if you leave the phone app.
Does Sona write to Jobber or HubSpot? +
Quo lists native logging to HubSpot, Salesforce, Pipedrive, and Jobber, including Sona call summaries. Sona can create a Jobber request during a live call when you configure that intent. If your book is Housecall Pro, GlossGenius, Clio matters, or a sheet with custom fields, an owned receptionist is built around that system instead of Quo's connector list.
Will Sona work after hours? +
Yes. Sona answers inbound calls 24/7 inside your Quo call flow. It is inbound-only and stays inside Quo. If credits run out and overages are off, it stops and follows your fallback — often voicemail. After-hours only helps if a human still owns dispatch, callbacks, and anything the script cannot handle.
Should I keep OpenPhone and add a custom receptionist? +
Often yes. Keep Quo for the shared inbox and SMS if the team already lives there. Do not stack Sona credits and an $8,000 build for the same rings. Forward overflow or after-hours to the owned line, or replace Sona when the credit cap, inbound-only limit, or CRM write is the actual leak.
