Quo (OpenPhone) alternatives
You're looking past Quo because Sona's included credits stretch to roughly 10 AI-answered calls a month, and a busy week uses that up by Tuesday. After that the meter moves to credit tiers, from $25 for 40 calls up to $199 for 600. If what you want is every missed ring picked up, here is how the field prices that job.
| Service | Bills by | Entry price | Overage published? |
|---|---|---|---|
| GreetKeeper | Answered call | $49 for 200 calls | Yes, $0.45 a call |
| Smith.ai | Per call | Free tier at $0 for 25 calls, then $3.00 a call | Yes |
| Ruby | Per minute | $250/mo for 50 minutes | No |
| Rosie | Per minute | Professional $49/mo for 250 minutes | No |
| Goodcall | Per unique caller | Starter $79/mo ($66 annual) for 100 unique customers | Yes |
| Quo (OpenPhone) | Per user per month, plus Sona AI agent credits (1 call = 100 credits) | Starter $15/user/month billed yearly or $19 monthly, with 1,000 Sona credits (about 10 AI calls) a month | Yes |

What GreetKeeper does differently from Quo (OpenPhone)
Every line below is on our pricing page or in the product today.
Why teams switch to GreetKeeper
- GreetKeeper sits beside Quo instead of replacing it. Point your missed or after-hours calls at your GreetKeeper number and your team's app stays exactly as it is.
- Pricing is per answered call, never per credit: Starter $49 covers 200 calls, Professional $149 covers 750, Scale $349 covers 2,000, and no user fee applies.
- Appointments land in Google Calendar or Outlook on every plan, after the assistant confirms the caller's name, number and time aloud.
- Robocalls and junk callers are screened out before anyone hears a hello, and screened calls are never counted.
- Calls that arrive together are all picked up at the same time, so nobody queues on a Monday rush.
- Your first 14 days are free, with the whole product switched on, no card and no onboarding charge.
Why people leave Quo (OpenPhone)
Not a general complaint about the category. The specific wall this vendor puts in front of you.
Most Quo customers signed up for the app: shared lines, SMS and a clean inbox for a small team. The AI side is metered separately, in credits, so a team that leans on Sona for evenings and weekends ends up paying a second meter on top of its user licences. Those licences also climb every time someone joins, before the new hire has picked up a single call.
What the bill does as you grow
The entry price is the cheapest month you will ever have. This is the shape of the rest.
Quo's bill has two meters. User licences run $23 to $35 a month each on annual billing, and AI calls beyond the included 10 are bought in credit tiers: $99 buys 250 calls, $199 buys 600, and overflow on those tiers costs $0.55 and $0.45 a call. GreetKeeper has one meter. Professional is $149 for 750 answered calls, Scale is $349 for 2,000, and a call past the allowance is $0.35 or $0.25. Screened junk and robocalls never touch that count.
What moving off Quo (OpenPhone) actually involves
Forwarding takes five minutes. Here is the part that takes an afternoon.
Quo stays where it is. Create a GreetKeeper account, choose an area code for the new line, and give the assistant your website address so it drafts your opening hours, offerings and common questions. Fix what's wrong, link Google Calendar or Outlook, and add the transfer number plus a backup number. Last, tell Quo to send unanswered or after-hours calls to your GreetKeeper line. The ring count lives in Quo's forwarding settings, and GreetKeeper picks up the instant a call lands.
Common questions
What is a good Quo alternative for answering calls with AI?
A receptionist priced by answered call, not by credits on top of user licences. GreetKeeper answers calls sent from any line, schedules into Google Calendar or Outlook and texts your on-call person with who rang and why. Plans start at $49 a month for 200 answered calls.
Is OpenPhone the same company as Quo?
Yes. openphone.com now redirects to quo.com, and the pricing page there lists the Starter, Business and Scale plans with the Sona AI agent. The figures on this page were read on quo.com in September 2026.
Can I try GreetKeeper before I change anything in Quo?
Yes. The first 14 days are free, with the whole product switched on and no card. Send only your evening and weekend calls to your GreetKeeper number during those two weeks, review the transcripts, then decide how much of your volume to route its way.
