OpenPhone (Quo) pricing explained: real costs per plan

What Quo costs, plainly

OpenPhone rebranded to Quo (the site is now quo.com), but the pricing is unchanged. Three plans, per user per month:

Plan	Annual (per month)	Monthly	Who it's for
Starter	$15	$19	Solo or a small shared line — calls, texts, the basics
Business	$23	$33	Teams that want auto call recording, CRM and phone menus
Scale	$35	$47	Bigger teams wanting AI call tags and priority support

Every plan includes one local or toll-free number per user, unlimited US and Canada calling and texting (subject to fair use), voicemail transcripts, and the Sona AI agent that answers calls. Paying annually is about 27% cheaper than month to month.

The costs the headline hides

A "pricing explained" page should give you the real bill, not the sticker. For Quo the extras are small and mostly unavoidable anywhere:

• Carrier texting registration. To text US numbers reliably, every provider has to register your business with The Campaign Registry. Quo passes through the standard fee: $19.50 one-time plus $1.50–$3 a month. This isn't a Quo markup — you'd pay it at RingCentral, Dialpad or anyone else.
• Extra numbers. Each phone number beyond the one per user is $5 a month.
• AI beyond the freebie. Sona includes about 10 calls a month free (1,000 credits). Lean on the AI receptionist harder and you buy a credit top-up — $25 a month for ~40 calls, up to $199 for ~600.
• Monthly vs annual. Paying monthly costs roughly a quarter more.

What you actually pay — a worked example

A two-person business on Starter, paying annually, that texts customers:

• 2 users × $15 = $30/month
• Carrier texting registration: $19.50 once, then ~$2/month
• First month ≈ $51.50, then ≈ $32/month — plus tax.

Add a second number for the business line and that's another $5. Nothing here is a nasty surprise, and it stays genuinely cheap — the point is just that "$15" is the per-seat sticker, not the bill.

The verdict

For a small business that mostly makes calls and sends texts, Quo is about as close to "what it says on the tin" as US business phone pricing gets. The only real additions are the carrier texting fees — which are universal — $5 extra numbers, and optional AI credits. Pay annually, ignore the AI top-ups unless you actually use the receptionist heavily, and the headline $15 a user is close to your true cost. If you want to see it against rivals, the RingCentral alternatives page puts Quo next to the field.
