OneBy vs Quo (formerly OpenPhone): 2026 Comparison
OpenPhone rebranded to Quo and added a metered AI agent. Here's the honest math on what it really costs, where their AI stops, and where OneBy picks up.
The OneBy Team
OneBy
First, housekeeping: if you're searching for OpenPhone and keep landing on something called Quo, you're not lost. OpenPhone rebranded to Quo in September 2025, keeping the same product and team and adding a bigger AI story around their agent, Sona. Same company, new name, new ambitions.
We updated this comparison for 2026 because the pricing model changed in a way that really matters for a small service business. Quo's numbers below are as of July 2026, per quo.com. OneBy launches in October 2026, and founders pricing is live now, so we'll compare like-for-like and show our math.
What Quo Is Great At
Credit where it's due, because there's real credit to give. Quo makes genuinely polished apps: iOS, Android, macOS, Windows, web. Shared numbers, team inboxes, texting from a business line, clean call routing. Their G2 rating is strong (4.7 stars across thousands of reviews, per G2 as of July 2026), they say they serve 90,000+ businesses, and the integration catalog is wide: Salesforce, HubSpot, Slack, Jobber, and more.
If your team is spread across ten cities and lives inside a laptop, Quo is a very good phone system. That was true when it was OpenPhone, and it's still true now.
For balance: their Trustpilot rating sits notably lower (3.7 as of July 2026), with complaints clustering around billing and support. Worth reading both before you decide.
The Pricing Math Nobody Shows You
Here's the part that gets glossed over. Quo's headline price is "starting at $15 per user/month." True, but that's the phone. The AI is a separate meter.
Per quo.com as of July 2026:
- Seats: Starter $15, Business $23, Scale $35 per user/month (billed annually; monthly billing runs higher)
- Sona, the AI agent, billed separately: $25/mo for 40 calls, $49/mo for 100 calls, $99/mo for 250 calls, $199/mo for 600 calls
- Overage: $0.45 to $1.00 per call beyond your credit tier
So what does a real service business actually pay? An example, using their published numbers:
| Monthly cost (example) | Quo (Business tier, 1 seat) | OneBy |
|---|---|---|
| Phone seat | $23 | Included |
| AI answering, ~100 calls/mo | $49 (Sona tier) | Included |
| Total, normal month | ≈ $72/mo | $49/mo ($39 founders) |
| Total, busy month (~250 AI calls) | ≈ $122/mo | Still $49/mo flat |
Add a second seat and Quo's number climbs again. And because Sona is credit-metered, your best month, the one where the phone won't stop ringing, is also your most expensive one. That's exactly backwards for a business that wants every call answered.
OneBy is one flat price. The AI Suite is $49/mo, and founders lock $39 for two years. Busy season doesn't change your bill.
Where Sona Stops, and Where OneBy Keeps Going
The deeper difference isn't price. It's where the AI's job ends.
Sona's scope, per Quo's own site: answer the call, take a message, answer FAQs, capture the lead, transfer to a human. All useful. But then it hands off, and someone on your team still has to create the job, book the visit, and send the invoice. Quo's own home-services page describes logging calls into Jobber, which tells you everything: they need someone else's software to finish the work.
OneBy is that other software, plus the phone. One system, one flow:
- The AI answers the call, day or night, and captures the details
- The call becomes a summary and a ticket, assigned to a real person
- The job gets scheduled
- The invoice goes out and the payment comes in
- Everything lands on one customer timeline
Quo answers the phone. OneBy runs the job.
A Side-By-Side Look
Both products are good. They're built for different businesses.
| Capability | Quo | OneBy |
|---|---|---|
| Polished apps on every platform | Yes | Web + mobile |
| Established reviews at scale | Yes (G2 4.7, per G2, July 2026) | Pre-launch, founders program |
| Big integration catalog | Yes | Core set at launch |
| AI receptionist included in flat price | No, metered add-on ($25–$199/mo) | Yes |
| Predictable bill in a busy month | No, per-call credits | Yes, flat |
| Turns calls into tickets automatically | No, message + handoff | Yes |
| Scheduling, invoicing, payments built in | No, via integrations like Jobber | Yes |
| Built specifically for the trades | Broad SMB, 11 verticals | Yes, trade-deep |
So Which One Do You Need
Honest answer: if you're a distributed team that mostly needs a beautiful phone app, shared numbers, and deep integrations into a CRM you already run, pick Quo. It's a mature product with years of reviews behind it, and OneBy doesn't launch until October 2026.
But if you're a plumber, electrician, HVAC shop, or any business where the phone call is the job, ask what happens after the AI takes the message. With Quo, the answer is: you (or another subscription) do the rest. With OneBy, the call becomes the ticket, the ticket becomes the schedule, the schedule becomes the invoice, and the invoice becomes money, without leaving one system or watching a credit meter.
The Short Version
Quo is a polished phone system with an AI add-on that's billed by the call. OneBy is an AI receptionist plus the whole job behind it, at one flat price an owner can actually budget. Pick based on where your work ends: at the message, or at the payment.
