Onyx Phone vs Google Voice for business
Google Voice is the phone many small businesses start with. For a team it is an add-on to Google Workspace, so you pay for Workspace and then for Voice on top. Onyx Phone is a business phone on its own: no other subscription, a number included for each user, and unlimited calling and texting on every plan.

What a team of five pays each month
Five people on Onyx Phone Starter cost $85 a month, billed monthly, with a number included for each person. Google Voice Starter is $50 a month, billed monthly for the same five people.
Google's prices are per user for Voice alone. Google says a team needs a Google Workspace plan, billed separately, to turn Voice on for more than one person, so the real cost per person is the Workspace plan plus the Voice plan. If you already pay for Workspace, Voice Starter is hard to beat on price. If you don't, Onyx Phone is one bill.
Where Google Voice is stronger
- If your team already lives in Gmail, Calendar, and Meet, Voice sits inside the tools you have.
- Voice Starter is $10 per user a month on top of a Workspace plan you may already pay for.
- Google Voice calls many countries at published per-minute rates. Onyx Phone's unlimited calling covers the US and Canada.
Where Onyx Phone is stronger
- No Google Workspace subscription. Onyx Phone is the only bill.
- Phone menus on every plan, and ring groups and call transfers on Business.
- Desk phones ring alongside the browser and the iPhone and Android apps.
- Call recording with AI summaries of each call on Business.
- Unlimited two-way business texting on every plan, registered with US carriers for you.
- A robocall screen and missed-call text-back.

Questions
Do I need Google Workspace to use Google Voice for business?
For a team, yes. Google says Workspace is required to turn on Voice for several users, and it's billed separately from Voice. Onyx Phone needs no other subscription.
Can I keep my Google Voice number?
Yes. Google Voice lets you port a number out. The Google Voice guide covers personal accounts and the Workspace guide covers business accounts.
Is Onyx Phone more expensive than Google Voice?
Voice Starter alone is cheaper per user. Add the Workspace plan a team needs, and Onyx Phone Starter at $17 per user is often the lower total, with texting included and a number for each user.
Included on every plan
Starter is $17, Business is $29, Scale is $42 per user a month, or less billed yearly. The plan includes a business number for each user and unlimited calling and texting in the US and Canada. Every plan starts with a 7-day free trial, and moving your current number over is free.
