Key takeaways
- RingCentral is the best fit for most small businesses at $29.99/user/month; Nextiva follows at $23/user/month with 24/7 support, and Zoom Phone is the cheapest entry at $12/user/month on its Metered plan.
- Grasshopper is the only flat-rate option here — $18/month for one number with no per-user fee — while every other service charges per user, per month.
- The single most important buying factor is the billing term: monthly billing costs up to 53% more than annual billing on RingCentral and Nextiva, so the price you see is rarely the price you pay.
- Metered plans look cheap until the team starts calling: Zoom Phone Metered bills every outbound minute, so a heavy-calling team pays less on an unlimited plan.

RingCentral
Best for: Small businesses that want one system for calls, video meetings and team messaging, with room to grow
RingCentral is the most complete system in this list: one subscription covers business calling, video meetings, team messaging and fax, with a single admin console and apps for desktop and mobile. Essentials costs $29.99 per user a month on monthly billing, or $19.99 a month when you pay annually, and it includes unlimited calls in the US and Canada, video meetings and 25 text messages per user a month.
The catch is the meter running in the background. SMS beyond 25 messages, toll-free minutes beyond the 100 pooled on Essentials and AI features such as the AI receptionist are all billed separately, so a heavy texting team pays more than the headline price. Buy RingCentral when you want one vendor for the whole communications stack; buy Ooma or Grasshopper when a phone line alone will do.
What we like
- One subscription covers calling, video meetings, team messaging and fax
- More than 600 integrations on the Advanced plan, including Salesforce and HubSpot
- 99.999% uptime SLA and a 14-day free trial on every plan
Watch out for
- Entry plan caps SMS at 25 messages per user a month and toll-free minutes at 100 pooled
- AI receptionist and conversation intelligence are paid add-ons, not part of the entry plan
- Taxes and a compliance cost-recovery fee sit on top of the per-user price
Nextiva
Best for: Small teams that want reliable calling and 24/7 human support behind it
Nextiva sells reliability first: a 99.999% uptime commitment, 24/7 live support on every plan, and a single app for voice, video meetings and team chat. Core costs $23 per user a month on monthly billing, or $15 a month when you pay annually, and it includes unlimited calling in the US and Canada, video meetings, team chat and an auto attendant.
Core also includes 50 AI transcriptions and 50 AI call summaries a month, which is generous for the entry tier. The limits to watch are call recording, which is a paid add-on on Core, and the 12-month minimum term on the annual price. Choose Nextiva when missed calls cost you customers and you want a human on the phone when something breaks.
What we like
- 99.999% uptime and 24/7 live support on every plan
- 50 AI transcriptions and 50 AI call summaries a month included on Core
- Unlimited US and Canada calling, video meetings and team chat on the entry plan
Watch out for
- Call recording is a paid add-on on Core, not included
- The annual price needs a 12-month minimum term for new customers
- SMS stops at 100 messages per user a month on Core
Ooma Office
Best for: Small businesses that want a simple phone system with no contract and no per-user surprises
Ooma Office is the plainest buy in this list, and that is the point: three plans, flat prices, no contract on any of them. Essentials costs $19.95 per user a month, with no annual-billing discount to chase, and it includes unlimited calling in the US, Canada, Mexico and Puerto Rico, a virtual receptionist, a mobile app and one toll-free number with 500 inbound minutes a month.
The trade-off is that Essentials is deliberately thin. There is no texting, no desktop app and no video meetings until Pro at $24.95 a month, and a one-time $29.95 activation fee applies. Pick Ooma when you want a phone system that just works and a bill that never changes; pick RingCentral or Nextiva when you need video and integrations in the same subscription.
What we like
- No contract on any plan — cancel any time
- Unlimited calling in the US, Canada, Mexico and Puerto Rico on every plan
- Virtual receptionist and mobile app included from Essentials
Watch out for
- No texting on Essentials — SMS starts on Pro at $24.95/user/month
- No desktop app or video meetings on Essentials; both wait for Pro
- A one-time $29.95 activation fee applies, plus taxes and fees
Zoom Phone
Best for: Teams that already live in Zoom and want phone service inside the same app
Zoom Phone turns the meetings app your team already knows into a business phone system, with one app and one admin console for meetings, chat and calls. The Metered plan costs $12 per user a month on monthly billing, or $10.50 a month when you pay annually, and it includes voicemail transcription, an auto attendant, call recording and domestic SMS.
The catch is the word metered: inbound calls are free, but every outbound minute is billed on top of the base price, so the plan only stays cheap for teams that mostly receive calls. A team that dials out all day pays less on Unlimited at $18 a month billed monthly. Buy Zoom Phone when your team already lives in Zoom; buy elsewhere when it does not.
What we like
- Cheapest entry point here at $12/user/month on the Metered plan
- One app and one admin console for meetings, chat and phone
- Voicemail transcription, call recording and SMS included on every plan
Watch out for
- Outbound calls on Metered are billed per minute on top of the $12 base
- Unlimited US and Canada calling costs $18/user/month billed monthly
- Phone needs a paid Zoom Workplace licence; the free meetings tier does not include it
Quo
Best for: Small teams that want a shared business number with calling and texting in one app
Quo, formerly OpenPhone, is the modern pick for small teams that live on calls and texts: every user gets a local or toll-free number, and shared numbers let the whole team answer one business line from any device. Starter costs $19 per user a month on monthly billing, or $15 a month when you pay annually, and it includes unlimited calling and texting in the US and Canada.
Starter also includes the Sona AI agent, with 10 free AI-handled calls a month, plus voicemail transcripts and an API. The limits are the integrations: HubSpot and Salesforce, phone menus and analytics all wait for Business at $33 a month, and a one-time $19.50 carrier fee applies. Pick Quo when a shared number and texting are the job; pick RingCentral when you also need video.
What we like
- Shared numbers let the whole team answer one business line
- Sona AI agent included, with 10 free AI-handled calls a month on Starter
- Unlimited calling and texting in the US and Canada on every plan
Watch out for
- CRM integrations and phone menus wait for Business at $33/user/month
- A one-time $19.50 carrier fee plus $1.50 to $3 a month in messaging fees apply
- No video meetings or screen sharing — it is phone and text only
Grasshopper
Best for: Solo owners who want one business number on the phone they already own
Grasshopper is the only flat-rate service in this list: you pay for a plan, not for seats, so adding teammates never raises the bill. True Solo costs $18 a month on monthly billing, or $14 a month when you pay annually, and it gives one business number with one extension, unlimited calls in the US and Canada, voicemail transcription and call forwarding — all through an app on the phone you already own.
The simplicity has edges. True Solo covers one number and one extension, so a team needs Solo Plus, and there are no video meetings and no CRM integrations at any price. Grasshopper also carries the lowest G2 score here, 3.9 from 162 reviews. Buy it when you are a solo owner who wants a professional number fast; buy a per-user system when the team is growing.
What we like
- Flat monthly rate — no per-user fee at all
- Runs entirely through an app, so there is no hardware to buy
- Voicemail transcription, call forwarding and custom greetings included
Watch out for
- True Solo covers 1 number and 1 extension — a team needs Solo Plus
- No video meetings and no CRM integrations at any price
- Lowest G2 score in this list at 3.9 from 162 reviews
Vonage
Best for: Mobile-first teams that want desk-phone support without paying for it on day one
Vonage Business Communications is built for teams that work from their phones: the entry Mobile plan covers unlimited calling and SMS, team messaging and a virtual receptionist through mobile and desktop apps, with no desk phone required. Mobile costs $19.99 per line a month, or $13.99 a line with the current 30% discount for new customers on a one-year contract.
The pricing is tiered by device, not by features alone. Desk phones need Premium at $29.99 a line a month, and call recording waits for Advanced at $39.99. The promotional price also locks you into a one-year contract with early termination fees. Pick Vonage when the team is mobile-first; pick Ooma when you want the same price with no contract at all.
What we like
- Unlimited calling and SMS on the entry Mobile plan
- Mobile and desktop apps included, so staff can work from anywhere
- 20 third-party app integrations on the entry plan
Watch out for
- Desk phones need Premium at $29.99/line/month
- The $13.99 price needs a 1-year contract for new customers only
- Early termination fees apply if you cancel inside the contract term
CloudTalk
Best for: Sales teams that call internationally and live in their CRM
CloudTalk is the international pick: local numbers in more than 160 countries, unlimited calls in the US and Canada, and 500 EU outbound minutes per user a month on the entry plan. Starter costs $34 per user a month on monthly billing, or $25 a month when you pay annually, and it includes IVR, call queues, click-to-call and more than 95 CRM, helpdesk and ATS integrations.
The price is the highest entry point in this list, and the tools that make CloudTalk a sales platform — the AI voice agents, power dialer and parallel dialer — are paid add-ons rather than included features. Buy CloudTalk when your team calls across borders and lives in its CRM; buy Aircall when the budget is tighter and the calling is mostly domestic.
What we like
- Local numbers in more than 160 countries on the entry plan
- 95+ CRM, helpdesk and ATS integrations, including HubSpot and Salesforce
- Unlimited calls in the US and Canada plus 500 EU outbound minutes per user
Watch out for
- Highest entry price in this list at $34/user/month billed monthly
- AI voice agents, power dialer and parallel dialer are paid add-ons
- Reviewers note onboarding can take time before the team is fully set up
Aircall
Best for: Small sales and support teams that want calls logged to the CRM automatically
Aircall is built for teams whose calls belong in the CRM: every call, note and outcome syncs automatically through more than 250 native integrations, including HubSpot, Zendesk and Pipedrive on the entry plan. Essentials costs $30 per license a month on annual billing, and it includes unlimited calls in the US and Canada, SMS, IVR, call recording with AI transcripts and 50 AI Voice Agent minutes a month.
The floor is the catch. Every plan needs at least 3 licenses, so a two-person team pays $90 a month, and Aircall publishes no month-to-month price at all — annual billing is the only published rate. AI call summaries and the power dialer also wait for Professional at $50 a license a month. Buy Aircall when CRM logging is the job; buy CloudTalk when you need international numbers instead.
What we like
- 250+ native integrations, including HubSpot, Zendesk and Pipedrive on Essentials
- 50 AI Voice Agent minutes a month included on the entry plan
- Set up in minutes with no hardware and 24/7 support on every plan
Watch out for
- A 3-license minimum means a 2-person team pays for 3 seats ($90/month)
- No month-to-month price is published — the $30 figure is the annual-billing rate
- AI call summaries and the power dialer wait for Professional at $50/license/month
The best voip service for small business buyers is not the cheapest one on the page — it is the one whose per-user price, minute charges and add-ons still make sense at your actual call volume. We ranked the nine services below by fit for the most common buyer — a US small business with 1 to 20 people answering real customer calls — and every price was checked on the vendor's own pricing page on November 4, 2026.
How to choose the best voip service for small business
- Count the seats, then check the minimum. Aircall needs 3 licenses, so a two-person team pays $90 a month; Grasshopper charges a flat rate instead, so a growing team never pays per seat.
- Decide metered or unlimited before you compare prices. Zoom Phone Metered starts at $12 a user a month, but every outbound minute is billed on top — a team that dials out all day pays less on Unlimited at $18.
- Read the billing term, not just the number. RingCentral Essentials is $19.99 a user a month on annual billing and $29.99 month to month; Nextiva Core is $15 against $23. The annual figure is the advertised one.
- Check what the entry plan leaves out. Texting waits for Pro on Ooma, call recording is an add-on on Nextiva Core, and desk phones need Premium on Vonage.
- Try it with real calls. Every service here offers a trial, free access or a money-back guarantee. Port one number, take real customer calls for a week, and check call quality on your own internet connection before you move the whole team.
A phone system is one part of how customers reach you. If they find you through chat first, our guide to customer service chatbots covers that side, and our AI chatbot guide for customer service compares the tools that answer when nobody picks up.

VOIP service for small business pricing: what you will actually pay
Take a five-person team on monthly billing. Grasshopper Solo Plus costs $32 a month, or $384 a year, and that is the whole bill — no per-user fee. Zoom Phone Metered costs $60 a month, or $720 a year, before outbound minutes; at about 3 cents a minute, 1,000 outbound minutes a month adds roughly $30, bringing it to $1,080 a year, the same as Unlimited at $90 a month. Quo Starter costs $95 a month, or $1,140 a year, plus a one-time $19.50 carrier fee. Ooma Essentials costs $99.75 a month, or $1,197 a year, plus a one-time $29.95 activation fee. Vonage Mobile costs $99.95 a month, or $1,199.40 a year — or $69.95 a month, $839.40 a year, in the first year on the 30% new-customer discount.
The dear end is wider apart. Nextiva Core costs $115 a month on monthly billing, or $1,380 a year, and $75 a month, or $900 a year, on annual billing. RingCentral Essentials costs $149.95 a month, or $1,799.40 a year, and $99.95 a month, or $1,199.40 a year, on annual billing. Aircall Essentials costs $150 a month, or $1,800 a year, on annual billing, with no month-to-month price published. CloudTalk Starter costs $170 a month, or $2,040 a year, and $125 a month, or $1,500 a year, on annual billing.
The same five people cost $384 a year at the cheap end and $2,040 at the dear end — a $1,656 gap that comes from flat-rate versus per-user pricing and from billing terms, not from call quality. Annual billing saves about $480 a year on RingCentral, $480 on Nextiva and $540 on CloudTalk, so it pays for itself if every seat lasts the year. Three costs sit outside every number above: taxes and regulatory fees, which every vendor adds; one-time fees such as Ooma's $29.95 activation and Quo's $19.50 carrier fee; and desk phones, which start around $60 to $100 each if the team wants them.
Know the difference: a full phone system vs a virtual phone number
The confusion in this category is between two different products that both get called VOIP. A full phone system — RingCentral, Nextiva, Zoom Phone, Vonage, CloudTalk, Aircall — gives every team member a seat, with call routing, voicemail, queues and integrations, and it charges per user per month. A virtual phone number — Grasshopper True Solo, and Quo at its simplest — gives the business one number that rings on phones the team already owns, and it charges a flat monthly rate.
The difference shows up the moment a second person joins. On a per-user system, the bill rises by one seat; on Grasshopper Solo Plus, the same $32 a month covers the whole team, because there is no per-user fee at all. The trade is features: a virtual number has no call queues, no CRM logging and no video meetings, while a full system has all three. If one person answers every call, a virtual number is enough. If calls need routing, recording or logging, buy the system.
There is a second distinction worth knowing: metered versus unlimited calling. Metered plans charge per minute for outbound calls, so the bill follows call volume; unlimited plans charge a flat rate per user whatever the volume. Zoom Phone Metered at $12 a user a month is the cheapest entry here, but a team making 1,000 outbound minutes a month pays about $30 extra for those minutes — exactly the price of stepping up to Unlimited.
Quick comparison: tool type by need
| Buyer | Best pick | Why |
|---|---|---|
| Solo owner, one number | Grasshopper | Flat $18/month, no per-user fees, runs on the phone you own |
| Team already on Zoom | Zoom Phone | From $12/user/month, phone inside the same app as meetings |
| Most small businesses | RingCentral | Full system — calls, video, messaging — from $29.99/user/month |
| Team that wants support | Nextiva | 24/7 live support and 99.999% uptime, from $23/user/month |
| Sales team calling internationally | CloudTalk | Numbers in 160+ countries, from $34/user/month |
| Sales or support team on a CRM | Aircall | 250+ integrations that log calls automatically, from $30/license/month |
Mistakes to avoid
- Budgeting on the annual price while paying monthly. RingCentral Essentials is $19.99 a user a month on annual billing and $29.99 month to month; Nextiva Core is $15 against $23. Compare tools on the billing term you will actually use.
- Buying metered when the team calls all day. Zoom Phone Metered looks cheapest at $12 a user a month, but outbound minutes are billed on top. If the team dials out for hours a day, Unlimited at $18 is the cheaper buy.
- Ignoring the minimum seat count. Aircall needs 3 licenses, so a two-person team pays $90 a month, not $60. Check the floor before you compare the per-seat price.
- Forgetting the charges outside the headline price. Ooma charges a one-time $29.95 activation fee, Quo a one-time $19.50 carrier fee, and every vendor adds taxes and regulatory fees. Price the first invoice, not the advertised rate.
- Paying for desk phones before the team asks for them. Every service here works through desktop and mobile apps. Vonage charges Premium for desk-phone support, so buy the apps-only plan first and add hardware only if staff want it.
How we chose
We checked each vendor's own pricing page on November 4, 2026 and recorded the starting price exactly as shown, including the annual-billing figure where the page lists one, and we ranked the services by fit for the most common buyer — a US small business with 1 to 20 people answering customer calls — not by brand size. Three figures need a note: Aircall publishes only its annual-billing rate, so its chart bar shows $30/license/month and no month-to-month figure is asserted; Nextiva's $23 month-to-month Core figure comes from Nextiva's own pricing guide, since its pricing page defaults to annual billing; and Zoom Phone's $12 month-to-month Metered figure comes from a published breakdown of Zoom's pricing page, which shows the $10.50 annual figure. Ratings come from G2 product and comparison pages checked on November 4, 2026. No vendor paid for a place in this list, and none of the links here are affiliate links.
What to do next
Start with the free trial or free access of your top pick and run one real week of customer calls through it. Check call quality on your own internet connection, confirm the number ports cleanly, and count what the first invoice actually adds in taxes and fees before you move the whole team. If the phones are sorted but new customers are not finding you, our monthly SEO service handles the visibility side — or compare providers in our guide to marketing platforms for small business SEO.

Frequently asked questions
What is the best VOIP service for a small business?
RingCentral is the best fit for most small businesses: calls, video meetings and messaging in one system from $29.99/user/month. Nextiva is the better pick when 24/7 support matters most, at $23/user/month. Zoom Phone is the cheapest entry at $12/user/month for teams that mostly receive calls.
How much does a VOIP service cost per month for a small business?
Entry prices run from $12 to $34 per user a month on monthly billing, or $18 a month flat for Grasshopper True Solo. A five-person team pays $60 to $170 a month before taxes, fees and add-ons, and annual billing cuts most of those figures by roughly a third.
Is there a free VOIP service for small business?
No service in this list has a free plan. The cheapest ways in are a free trial — 7 days on Grasshopper and Quo, 14 days on RingCentral and CloudTalk — or free access to test Aircall. Grasshopper True Solo at $18 a month is the cheapest paid starting point.
What is the difference between a VOIP service and a virtual phone number?
A VOIP service is a full phone system: multiple users, call routing, voicemail and integrations, priced per user. A virtual phone number, like Grasshopper True Solo, is one number that forwards to a phone you own, priced flat. Teams need a VOIP service; solo owners can often manage with a virtual number.
Do I need desk phones for a VOIP service?
No. Every service in this list works through desktop and mobile apps, and most small teams never buy a desk phone. Vonage is the exception to watch: its entry Mobile plan covers apps only, and desk phones need Premium at $29.99/line/month. Buy hardware only after the team asks for it.
Can I keep my existing business number when switching to VOIP?
Yes. Every provider in this list supports number porting, and most include one local or toll-free number per user in the entry price. Start the port before cancelling the old service, and keep the old line active until the port completes, which usually takes a few business days.
What should I check before buying a VOIP service?
Check four things: whether the price quoted is monthly or annual billing, whether outbound minutes are metered or unlimited, what the minimum seat count is, and what sits outside the headline price — taxes, fees, activation charges and add-ons like call recording. Then run the free trial with real calls.
