What is a business VoIP service?

A business VoIP service, also called a cloud phone system, delivers your company’s phone calls over the internet instead of traditional phone lines. The provider hosts the phone system, so there is no on-site phone box to maintain.

How a business VoIP service works

Best business VoIP service: comparison table

Here is how the eight business VoIP service options compare on what each vendor publishes. Prices are per user per month in US dollars.

I left 8×8 out of the table because its plans page lists no per-user prices and points to a custom quote.

1. RingCentral: best business VoIP service for clear tiers

Price: RingCentral lists Core at $20 per user per month on annual billing ($30 monthly), Advanced at $25 ($35 monthly) and Ultra at $35 ($45 monthly). An AI Customer Engagement Bundle is contact-sales.

What is included: Core has unlimited domestic calling, on-demand call recording, 100 toll-free minutes, 25 SMS users a month and HD meetings for 300 participants. Advanced adds CRM integrations, multi-site connectivity, core reporting, 1,000 toll-free minutes and 100 SMS users. Ultra adds 10,000 toll-free minutes and 200 SMS users.

Add-ons: AI Receptionist is an add-on on Core, Advanced and Ultra, from $39. Phone rental requires a multi-year contract, and SMS requires registration that may carry extra fees.

Pros

• Three published tiers with clear annual and monthly prices
• Toll-free minutes and SMS allowances are spelled out per plan

Cons

• Key extras such as AI Receptionist and queues cost more
• Trial terms are inconsistent on the page (14 days in the FAQ, five users in a footnote)

Choose it if you want a business VoIP service with published tiers and room to grow into reporting. Skip it if you only need basic calling and want the lowest price.

2. Nextiva: lowest entry price among full-suite plans

Price: NEXT Core is $15 per user per month on annual billing and $23 monthly. NEXT Engage is $25 annual and $50 monthly. NEXT Scale is $75 annual, with no monthly price listed. Annual pricing applies to new customers with 1 to 100 employees on a paid term of 12 months or longer.

What is included: Core has unlimited voice and video, 100 business texts per user, shared and personal inboxes, basic CRM and ticketing and a set of AI transcription and summary uses. Engage adds live chat, 500 texts per user, 2,000 toll-free inbound minutes and single sign-on. Scale adds unlimited texts and 10,000 toll-free inbound minutes.

Pros

• Cheapest published annual entry price among the larger suites
• Texts, toll-free minutes and AI uses are quantified per tier

Cons

• Monthly billing on Engage is double the annual price
• Shared inboxes are capped at 1, 3 or 10 depending on tier

Choose it if you can commit to a 12-month term. Skip it if you need month-to-month flexibility on a higher tier.

3. Zoom Phone: best cloud phone system for Zoom users

Price: Zoom lists US & CA Unlimited at $16 per user per month billed annually ($18 monthly), Pro Plus at $20.50 ($24 monthly) and Business Plus at $24.50 ($29 monthly). These are bundled with Zoom Workplace Basic, Pro and Business.

What is included: All three include a domestic phone number and metered international calling. US & CA Unlimited covers domestic calling, SMS and MMS, 50 pages a month of online fax, call recording and AI post-call summaries. Pro Plus and Business Plus include unlimited domestic calling and 30-hour meetings; Business Plus adds unlimited domestic fax and meetings for up to 300 participants.

Pros

• Phone and meetings in one Zoom account
• Annual and monthly prices both published

Cons

• Zoom’s page describes the entry plan’s domestic calling as “unlimited or metered,” so confirm which applies
• International calling is metered

Choose it if your team already runs meetings in Zoom. Skip it if you want one flat price that includes SSO on the middle tier, since Pro Plus does not list it.

4. Dialpad: AI-first VoIP phone service for small business

Price: Dialpad Connect Standard is $15 per user per month and Pro is $25. Enterprise is contact-sales. The page shows a Monthly/Annual toggle but states only one price per plan, and its buy links point to yearly billing, so treat these as likely annual prices and confirm at checkout.

What is included: Standard lists unlimited calls, HD calls and meetings, real-time transcripts, instant call summaries, built-in messaging and AI-powered meetings. Pro adds key CRM integrations and 24/7 support. It offers a 14-day free trial.

Pros

• Call summaries and transcripts appear on the entry plan
• 14-day free trial

Cons

• Billing period for the listed prices is not confirmed on the page
• CRM integrations require Pro

Choose it if you want AI summaries from day one. Skip it if you need a published monthly-billing price before you commit.

5. Quo (formerly OpenPhone): best for very small teams

Price: Quo’s page shows Starter at $19 per user per month ($15 on annual billing, $180 a year), Business at $33 ($23 annual, $276 a year) and Scale at $47 ($35 annual, $420 a year).

What is included: Each user gets one local or toll-free number, with extra numbers at $5 a month. Starter covers calling and messaging to US and Canadian numbers, voicemail transcripts and manual call recording, with shared numbers for up to 10 paid users. Business adds AI call summaries, group calling, phone menus, automatic recording and HubSpot and Salesforce integrations.

Quo says messaging requires Campaign Registry business registration ($19.50 one-time plus $1.50 to $3 a month). It offers a 7-day free trial.

Pros

• Low published annual prices and free number porting
• Simple three-tier structure

Cons

• Calling and messaging cover the US and Canada; international is billed per use
• Messaging registration adds cost

Choose it if you are a small US team that wants a lightweight cloud phone system. Skip it if you need international calling bundled in.

6. Vonage: tiered by company size

Price: Vonage Business Communications lists Mobile, Premium and Advanced plans priced by company size. For the small and medium tiers, standard prices are $17.99, $27.99 and $37.99 per user per month, with 12-month promotional prices of $12.59, $19.59 and $26.59. A single-employee tier is a little higher. Vonage’s page does not label which prices are annual or monthly.

Billing terms: The promotion needs a minimum one-year contract on new accounts and is valid through December 31, 2026. Cancelling during the term may trigger early termination fees.

What is included: Mobile has apps, unlimited domestic calling, SMS and MMS and voicemail. Premium adds desk phone support, video meetings for up to 200 participants, team messaging and single sign-on. Advanced adds 15 hours a month of on-demand call recording, visual voicemail with transcription and call groups.

Pros

• Clear feature ladder from Mobile to Advanced

Cons

• Price basis is unclear on the page
• Early termination fees are a real risk

Choose it if you are comfortable with a one-year term. Skip it if you want a flexible month-to-month business VoIP service.

7. Microsoft Teams Phone: best for Microsoft 365 shops

Price: Per user per month, billed yearly: Teams Phone Standard is $10 and brings no calling, so you bring your own phone service through Calling Plans, Operator Connect or Direct Routing. Pay-as-you-go calling in US zone 1 is $13. A Calling Plan with 3,000 domestic minutes (US, UK and Canada) is $17. A plan with domestic and international calling is $34.

Key condition: Every Teams Phone plan requires a separate Microsoft Teams license, so the real cost is higher than the sticker. Standard has a one-month free trial that then converts to a 12-month paid subscription.

Pros

• Lowest entry price if you already pay for Teams
• Flexible choices for how calls reach the public phone network

Cons

• Needs a separate Teams license on every plan
• The lowest tier includes no calling

Choose it if your staff already live in Teams. Skip it if you want one all-inclusive per-user price.

8. GoTo Connect: quote-based cloud phone system

GoTo’s pages list plans named Phone System, Phone System + AI Receptionist, Customer Experience (CX), CX Complete and Contact Center, but no prices or free trial; you contact sales or request a demo. Number porting is listed as included on four of the five plans. The comparison table shows 1,000 shared toll-free minutes, calling to 50+ countries (which may vary by region) and unlimited auto attendants, ring groups and dial plans on all five plans, with video meetings of up to 250 participants.

Pros

• Generous feature limits listed

Cons

• No published prices or billing terms

Choose it if you are happy to get a custom quote. Skip it if you want to price a business VoIP service before talking to a salesperson.

How much does a business VoIP service cost?

Among the vendors that publish prices, a business VoIP service runs from $10 to about $35 per user per month on annual billing for most plans; Nextiva Scale is $75. Month-to-month billing is usually higher: RingCentral Core is $30 monthly versus $20 annually, and Nextiva Engage is $50 versus $25.

Business VoIP service cost example for 10 users

This example multiplies each vendor’s published entry-level per-user price by 10 users. It excludes taxes, add-ons, hardware and messaging fees.

How to choose a VoIP phone service for small business

• Confirm the billing basis. Check whether a listed price is annual or monthly, and what a 12-month term commits you to.
• Count what is bundled. Compare toll-free minutes, texting allowances, recording and fax across tiers.
• Check where you call. Several plans cover the US and Canada only, with international calling metered or billed per use.
• Match your existing tools. Zoom, Microsoft Teams or a CRM may already decide the shortlist. See our guide to CRM software for small business, and our project management software guide if calls need to feed task tracking.
• Test the trial. Listed trials run from 7 days (Quo) to one month (Teams Phone Standard).

Common business VoIP service mistakes

• Comparing an annual price from one vendor with a monthly price from another.
• Assuming texting is free; registration and per-message fees may apply.
• Signing a long contract for a promotion without reading the early termination terms, as Vonage’s page warns.

In short

The best business VoIP service depends on your stack and your contract tolerance. Nextiva and Quo have the lowest published annual entry prices at $15 per user (Dialpad Connect is also $15, billing period unconfirmed), Zoom Phone starts at $16 and RingCentral at $20. Microsoft Teams Phone starts at $10 but needs a Teams license, and GoTo Connect requires a quote. Use the 10-user example to compare like for like, then confirm current pricing and terms before buying.

Business VoIP service: FAQ

What is the best business VoIP service for a small business?

There is no single winner, but RingCentral, Nextiva, Zoom Phone, Dialpad and Quo are strong shortlist options with published per-user prices. Pick based on your existing tools, your contract tolerance and the extras you need.

How much does a business VoIP service cost per user?

Published annual-billing prices range from $10 (Microsoft Teams Phone Standard, calling extra) to $35 (RingCentral Ultra, Quo Scale) for most plans; Nextiva Scale is $75. Monthly billing is generally higher, for example $30 versus $20 for RingCentral Core.

What is a cloud phone system?

A cloud phone system is a business phone system hosted by a provider and delivered over the internet. Staff use desk phones or apps instead of an on-site phone box.

Which VoIP phone service for small business is cheapest?

Among published annual prices, Microsoft Teams Phone Standard is $10 per user but includes no calling and needs a Teams license. Nextiva NEXT Core, Dialpad Connect Standard and Quo Starter are $15, though Dialpad’s billing period is not confirmed on its page.

Does Microsoft Teams Phone include calling?

Not on its $10 Standard plan, which requires you to bring your own phone service. Plans at $13, $17 and $34 per user per month add pay-as-you-go or bundled calling, and every plan needs a separate Teams license.

Is there a free trial for business VoIP service?

Some vendors offer one: Quo lists 7 days, Dialpad Connect 14 days and Teams Phone Standard one month. RingCentral’s FAQ says 14 days, but a footnote limits the trial to five users, so confirm the terms.

Do I need a long contract for a VoIP phone service?

It depends on the vendor. Nextiva’s annual prices require a 12-month or longer term, Vonage’s promotion needs a one-year minimum with possible early termination fees, and Quo, RingCentral and Zoom publish monthly prices too.

Can I keep my existing business phone number?

Often yes. Quo says porting is free, Zoom lists number porting on all three Phone plans, GoTo Connect lists it on four of its five plans, and Vonage requires a Letter of Authorization. Nextiva’s page does not mention porting, and Dialpad, RingCentral and Teams Phone were not verified, so check fees and timelines before you switch.
