OpenPhone and Google Voice are two of the simplest ways for a small team to get a real business number without standing up a full cloud phone system. They aim at the same buyer, the startup, the solo operator, the small sales or support crew, but they solve the problem from opposite ends. OpenPhone is a modern, collaboration-first app built around shared numbers, a team inbox, and built-in AI. Google Voice is a lightweight number that lives inside Google's ecosystem, cheap and dead simple, but tied to a Workspace subscription once you go past one person.
One quick note before the numbers: OpenPhone has rebranded to Quo. The openphone.com domain now redirects to quo.com, and listings and reviews still appear under both names. We use the Quo plan names (Starter, Business, Scale) throughout. This comparison uses published, per-tier numbers as of June 2026, both confirmed from the providers' own pages, so you can see exactly where each one gates the features you care about and what you would really pay. Pricing changes often, so verify current pricing on each provider's site before you sign.
At a glance
Here is how the two stack up on the points that decide most small-team purchases. All prices are the starting per-user rate as of June 2026. Quo annual rates are the effective monthly figure; Google Voice team prices exclude the required Workspace subscription.
| Feature | OpenPhone (Quo) | Google Voice |
|---|---|---|
| Starting price (annual) | $15 / user / mo (Starter, annual) | $10 / user / mo (Starter team) plus Workspace |
| Top tier | Scale, $35 / user / mo (annual) | Premier, $30 / user / mo plus Workspace |
| Requires another subscription | No | Yes, team tiers need a paid Google Workspace plan |
| Shared numbers and team inbox | Yes, a core strength | No, single-user numbers |
| Built-in AI (tier) | Sona AI on Starter; AI call summaries at Business | Voicemail transcription; no deep call AI |
| CRM integration (tier) | HubSpot and Salesforce at Business ($23) | No native CRM connectors |
| Best for | Small sales and support teams | Individuals and simple Workspace-based teams |
Pricing
The headline numbers look close, but the billing models are not. OpenPhone (Quo) runs three per-user tiers and offers a real annual discount: Starter at $15 per user per month on annual ($19 month-to-month), Business at $23 on annual ($33 monthly), and Scale at $35 on annual ($47 monthly). The price is all-in for the app; there is no separate platform subscription to buy.
Google Voice team plans run Starter at $10 per user per month, Standard at $20, and Premier at $30. The line item is lower, but there is a catch that changes the math: Google Voice team tiers require a separate paid Google Workspace subscription, billed on top of the Voice fee. So the real per-seat cost is the Voice price plus whatever Workspace plan you run. Google also offers a free personal tier and paid individual plans (around $10 to $20 per month) that do not need Workspace, but those are single-user products, not team plans.
A few cost notes that apply to both. Quo's annual rate is the headline; month-to-month runs roughly 20 to 30 percent higher. Google Voice is month-to-month per user, but remember the Workspace requirement on team tiers. On top of any plan, taxes and regulatory fees typically add about 15 to 25 percent. Quo also has model-specific extras: about $5 per month per additional number, a one-time roughly $19.50 carrier registration fee for SMS, a small monthly SMS maintenance fee, and AI overage charges of roughly $0.45 to $1.00 per call beyond the included 1,000 automation credits. Number porting is supported on both, with the specific fee unconfirmed.
Features and what is gated
The plan price matters less than what each plan unlocks, and this is where the two part ways. Read the gating before you read the price.
OpenPhone (Quo) builds around team collaboration and AI. Starter ($15 annual) includes one number per user, US and Canada calling and messaging, voicemail transcripts, the Sona AI agent, and 1,000 automation credits, with a few caps: up to 10 shared-number users, manual recording, and up to 10 open tasks. AI call summaries and transcripts, group calling, call transfers, HubSpot and Salesforce integrations, phone menus, automatic recording, analytics, and unlimited shared-number users unlock at Business ($23). The top Scale ($35) tier adds AI call tags, dedicated onboarding, and priority plus inbound phone support. The shared-number and team-inbox model is the standout: it is built for a team handling calls and texts together.
Google Voice gates a simpler, lighter set. Starter ($10 team) covers a unified number, unlimited US domestic calling and texting, 24/7 support, three-way calling, transfers, recording, and desk-phone support for up to 10 users. Auto attendants and ring groups, call queuing, eDiscovery, and SIP Link unlock at Standard ($20) with unlimited users. The top Premier ($30) tier adds international billing locations, automatic call recording, and advanced reporting through BigQuery. What you do not get at any tier: shared inboxes, deep call AI, native CRM connectors, or real contact-center tooling. Voice is a number, not a collaboration platform.
Integrations
This one tilts toward Quo. OpenPhone (Quo) ships native CRM integrations for HubSpot and Salesforce starting at the Business tier, so a small sales or support team can log calls and texts against the right record without a workaround. It is not a sprawling enterprise marketplace, but for the teams it targets, the connectors that matter are there.
Google Voice's integration story is really one integration: Google Workspace. It ties tightly into Gmail, Calendar, and Meet, which is genuinely convenient if your whole company already runs on Google, and voicemail transcription lands in your inbox. But there are no native third-party CRM connectors, so if your workflow lives in HubSpot or Salesforce, Voice leaves you to bridge the gap yourself. If integration depth beyond Google is your deciding factor, Quo is the stronger choice.
Reliability and support
Reputation favors Quo on the score. OpenPhone (Quo) rates about 4.7 out of 5 on G2 across roughly 3,294 reviews (listed under the Quo name), one of the higher marks in this category, with reviewers praising the modern app and fast setup. Its weak spots are model-specific rather than reliability: it is US and Canada centric with limited international coverage, and its AI runs on credits with overage charges, so heavy users should watch the meter.
Google Voice rates about 4.1 out of 5 on G2 across roughly 151 to 160 reviews, riding on Google's reliable infrastructure and the convenience of the ecosystem. The common complaints are about depth, not uptime: limited IVR, no real contact-center tooling, and an app that some users find buggy or missing features as a team grows. For a small team that wants responsive in-app support and an actively developed product, Quo has the edge.
Which should you choose?
There is no single winner here, there is a winner for your situation. Three quick recommendations:
- Small sales or support team that handles calls together, choose OpenPhone (Quo). Shared numbers, a team inbox, built-in AI summaries, and HubSpot or Salesforce integrations at the Business tier make it the better fit for a team that works the phone as a unit, even at the higher per-seat price.
- Individual or Google-native team that wants the cheapest simple number, choose Google Voice. If you already pay for Google Workspace and just need reliable calling and texting tied into Gmail, Calendar, and Meet, Voice's $10 Starter team tier is hard to beat, as long as you accept the Workspace requirement and the lack of shared inboxes.
- You need shared inboxes plus deep AI, lean to Quo; you need a free solo line, lean to Google. Google Voice has a genuinely free personal tier for one user, which Quo does not match. But the moment you need a team to collaborate on calls and texts with AI in the loop, Quo is built for that and Voice is not.

FAQ
Is OpenPhone (Quo) or Google Voice cheaper?
Google Voice is cheaper on the line item, but the comparison is not even. As of June 2026, Google Voice team plans start at $10 per user per month (Starter), $20 (Standard), and $30 (Premier), but team tiers require a separate paid Google Workspace subscription billed on top. OpenPhone, now rebranded to Quo, starts at $15 per user per month on an annual term (Starter), then $23 (Business) and $35 (Scale). Once you add the required Workspace license to Google Voice, the gap narrows. Month-to-month billing on Quo runs higher and taxes and fees add about 15 to 25 percent on both. Verify current pricing before you buy.
Does Google Voice require Google Workspace?
Google Voice team plans (Starter, Standard, Premier) require a separate paid Google Workspace subscription, billed on top of the per-user Voice fee. There is a free personal tier and paid individual plans that do not need Workspace, but the business team tiers do. Factor the Workspace cost into any Google Voice comparison, because the Voice price alone understates the real bill.
Which is better for a small sales or support team, OpenPhone (Quo) or Google Voice?
For a small sales or support team, OpenPhone, now Quo, is usually the better fit. It is built around shared phone numbers, a team inbox, and built-in AI like call summaries and transcripts, with CRM integrations for HubSpot and Salesforce at the Business tier. Google Voice is better for simple internal calling inside an existing Google Workspace, but it lacks shared inboxes, deep AI, and real contact-center tooling. If you need team collaboration on calls and texts, Quo is the stronger choice.
