Best business phone system for Google Workspace

If your company runs on Google Workspace, the best business phone system is Google Voice in one specific case: you already pay for Workspace and each person mainly needs their own line. Then the phone is a $10 to $30 per user add-on and nothing else comes close on total cost. Outside that case the answer changes, because Google Voice sells no toll-free number on any plan, puts shared main lines behind the $20 tier, and requires a Workspace licence for every user once more than one person is on the system.

Nearly every article on this question assumes that the integrated option is automatically the cheapest one. That is worth checking rather than assuming, because the Google Voice price card and the Google Voice invoice are two different numbers, and the gap between them is the whole decision.

What a Google Workspace team actually pays for phone service

Google sells Voice as a per user add-on to Workspace. Both prices below were read at Google's own pricing pages on August 30, 2026. The combined column adds Workspace Business Starter at $7 per user, which is the cheapest Workspace plan that satisfies Google's requirement.

The number most teams should budget is the middle row. A business buys a phone system so that one published number reaches whoever is free, and that capability starts on Standard. So the honest entry price for a Workspace team is $27 per user per month, not the $10 on the card.

If you already pay for Workspace, ignore the combined column entirely and read the Voice column. That is the real comparison, and at $10 or $20 on top of licences you already own, Google Voice is genuinely hard to beat. The full breakdown of tiers, limits and the Workspace requirement sits on our Google Voice for business page.

Where Google Voice stops, whatever you are willing to pay

Three limits are absolute rather than financial. No tier removes them, so if any one applies to you, the integrated option is off the table before price enters the conversation.

• No toll-free numbers. Google Voice publishes local numbers only. There is no plan, add-on or price that gets you an 800, 888, 877, 866, 855, 844 or 833 number. If customers reach you on a toll-free line, you run a second provider alongside Google or you choose something else. Our toll-free number service page covers who sells them and what the minutes cost.
• Workspace is required for multiple users. Google states that Workspace is needed to enable Voice for more than one user in your organization. For a Microsoft 365 company this means paying for a second productivity suite purely to unlock telephony, which is roughly $7 per user per month of pure overhead.
• Starter has a hard 10 user ceiling. It is not a soft limit you grow through. An eleventh person moves the whole account to Standard at $20 per user, for everybody, not just the new hire.

Is Google Voice good enough as a business phone system?

For a lot of Workspace companies, yes. Provisioning a user is a checkbox in an admin console you already use, the number lives in the same identity as the email address, and calls, Calendar and Meet behave as one product rather than three. That integration is real, and it is the main reason to choose it. Teams that lean on Workspace this heavily often end up automating the rest of the desk work too, and an AI assistant that schedules meetings and drafts email tends to arrive on the same shortlist for the same reason.

The weakness is depth rather than quality. Ring groups exist but the routing logic is basic, reporting is thin until you reach BigQuery on Premier, and recording that happens automatically on every call is a $30 per user feature. None of that matters to a five person consultancy. All of it matters to a twenty person practice that records calls for compliance.

When to buy telephony separately instead

Buy phone service on its own when the phone is doing real work rather than just ringing. Concretely, that means one or more of the following is true: you need a toll-free number, you record every call as a control rather than as a convenience, you are on Microsoft 365, or you want a menu and ring groups without also buying storage and documents for every user.

The comparison to run is like for like. Price the cheapest plan at each provider that carries your actual requirements, not the entry plan. For a Workspace company that needs a shared main line, that is $27 per user at Google. Phoner puts the phone menu, ring groups, shared numbers, business texting, call recording and toll-free numbers on Team at $29 per user billed yearly, with no suite subscription underneath it and no seat minimum. Whether $27 or $29 wins depends entirely on whether you wanted the Workspace licence anyway, which is exactly the question most comparisons never ask.

Does Google Voice work with Microsoft 365?

Not as a way to avoid Workspace. Google Voice for multiple users requires a Google Workspace subscription regardless of what your email runs on, so a Microsoft 365 company adopting Google Voice ends up paying for two productivity suites. Voice does not integrate with Outlook or Teams the way it integrates with Gmail and Calendar, so you also lose the single benefit that made the integrated option attractive in the first place. For Microsoft shops, a standalone provider is usually both cheaper and better integrated.

Is Google Voice HIPAA compliant for a medical practice?

It can be, in one configuration. Google's own HIPAA implementation guide lists Google Voice for managed users only as included functionality and states that licensed users of Google Voice are covered under the Google Workspace Business Associate Agreement. That requires a managed Workspace account, a signed BAA, and Voice licences assigned to the staff who handle protected health information. A personal or free Google Voice account is not covered by any BAA and should not be used for patient calls. This is one area where Google is ahead of much of the market, and worth weighing seriously if you are a covered entity.

How many people answer the phone?

This is the question that settles it, and it is worth answering before you compare anything. Google Voice is billed per user, and only staff who make or take calls on a business number need a licence. A twelve person company where three people answer the phone is a three licence purchase. Get that count right first, because every figure above multiplies by it, and a shortlist built on the wrong headcount will pick the wrong product.

Once you have the number, price the same requirement at two or three providers. If you want the wider market rather than a head to head, our VoIP providers comparison prices thirteen of them at source, including which ones will not publish a rate card at all.
