The best business phone systems for most small teams are cloud (VoIP) services such as Aircall, Nextiva, Zoom Phone, Dialpad and Ooma, which list plans from about $15 to $50 per user per month, as listed October 2026. Choose by team size and how you work: sales and support teams that live in a CRM fit Aircall or Dialpad, budget teams fit Unitel Voice, 800.com or Ooma, and companies already paying for Zoom fit Zoom Phone. Always compare the annual price with the month-to-month price, the minimum number of seats, and the trial or refund window before you sign.

This guide is for owners and managers choosing a phone system for a small team, from a solo owner who needs a separate business number to a sales or support desk that takes calls all day. We compared providers, covering full cloud platforms, a carrier bundle and virtual number services, using their official pricing pages.
The listed price is only the starting point. Seat minimums, activation fees, extra number fees, taxes and promotional rates that rise after 12 months all change what you pay, and call recording, texting and AI transcription often sit on higher tiers.
Below you will find each pick with its pricing, trial terms and trade-offs, then cost math for a 5-person team, a feature guide by plan tier, red flags to check before you sign, and cheaper alternatives.

More about Zoom Phone

We compared each provider on listed price per user or per account (annual and monthly), seat minimums, included calling and numbers, trial or refund terms, contract terms, extra fees, AI and contact center features, and integrations. Prices and terms come from each company's official pricing pages, checked October 11, 2026, and regulatory history from the FTC. We did not test call quality ourselves. Where a company did not publish a fact on the pages we could open, we say "Not published." Prices change often, so confirm current pricing with the provider before you buy. Read our full methodology.
How much a business phone system costs
Most cloud phone systems charge per user per month. As listed October 2026, entry plans from the providers we compared range from $6.99 per month (Unitel Voice Solo, billed annually) to $30 per user per month (Aircall Essentials, billed annually). Mid-tier plans with call recording, CRM integrations and analytics usually land between $25 and $50 per user.
What moves the price
Billing term. Annual billing is almost always cheaper. Nextiva Engage is $25 per user annually and $50 month to month.
Seat minimums. Aircall requires at least 3 seats, so its real entry cost is $90 per month on annual billing.
Per user vs. per account. 800.com and Unitel Voice price some plans by account, which favors teams with several light users.
Add-ons. Extra numbers, call recording, AI minutes and analytics are often extra. Aircall lists extra numbers at $6 per month; Phone.com lists call recording at $7.99 per month below Pro.
One time and recurring fees. Ooma charges a $29.95 activation fee, and several providers note that taxes and regulatory fees are added on top.
Promotions. Vonage’s promotional rates last 12 months, then rise to list price.

Desk phones are optional with all of these services because each offers desktop and mobile apps. If you want physical handsets, budget for them separately.
How to choose a business phone system
Count real users. List who needs a direct number, who only needs to answer a shared line, and who never takes calls. Account-priced plans can be much cheaper for teams with many light users.
Map your call flow. Do callers need a menu (auto attendant or IVR), queues, after-hours routing or a ring group? Confirm the plan tier that includes each one.
Check integrations. If your team works in a CRM or help desk, check that the integration is native and which plan includes it.
Decide on AI. Transcription, summaries and coaching are included on some plans (Dialpad, Aircall Professional, Ooma Pro Plus) and paid add-ons on others.
Compare the full price. Add seat minimums, number fees, activation fees, taxes, and what happens when promotional pricing ends.
Test before you commit. Use a free trial or money-back window to place calls from your office internet and mobile network, port a test number, and call the provider’s support line.
A simple rule: solo owners and very small teams should start with a low-priced virtual number service, sales and support teams should start with a CRM-friendly platform, and teams that already pay for Zoom or a carrier should price the bundle first.
Cloud VoIP, carrier bundles and virtual numbers: which type fits
Nearly every provider on our list is a cloud (VoIP) phone system, meaning calls run over the internet and you manage users and routing in a web dashboard. The differences are in how the service is packaged.

Traditional on-premises PBX hardware still exists, but none of the picks here require it. A cloud system lets you add users the same day and take your business number on your cell phone through an app.
Features that matter, and which plan tier usually has them
Unlimited domestic calling. Standard on entry plans from Zoom Phone, Dialpad, Aircall, Unitel Voice and Ooma. Ooma also covers Mexico and Puerto Rico. 800.com’s Startup plan is capped at 250 minutes.
Auto attendant (IVR). Included on Aircall Essentials and Ooma Essentials (virtual receptionist).
Business texting. Included on Aircall Essentials, Zoom Phone and Nextiva Core. Ooma starts text messaging at Pro with 250 messages per month.
Call recording. Included on Aircall Essentials and Ooma Pro; a $7.99 add-on on Phone.com below Pro.
Toll-free numbers. One free on Ooma Essentials and Nextiva Engage; 800.com focuses on toll-free and vanity numbers.
AI transcription and summaries. Built in on Dialpad, on Aircall Professional and on Ooma Pro Plus.
Fax. Included on Zoom Phone (50 pages per month on the entry plan) and Ooma Essentials (digital fax).
Before you port your main number, ask each provider how 911 calls are routed and how to keep your registered address current, since internet calling depends on the location you set.
Red flags when signing up
Promotional pricing with no end date shown. Ask for the price in month 13 in writing.
Hard to cancel. In November 2022 the FTC ordered Vonage to pay $100 million in refunds after alleging it made cancellation difficult and charged junk fees, and required it to offer cancellation through the same method customers used to sign up. Ask any provider how cancellation works before you sign.
Early termination fees. Ask whether annual plans can be cancelled early and what you owe.
Hidden fees. Look for activation fees, number fees, and taxes and regulatory fees listed in fine print.
Number ownership. Confirm you can port your number out if you leave, and get the steps in writing.
“Unlimited” with a fair use policy. Read the policy if your team makes high volumes of outbound calls.
Cheaper alternatives and when you may not need a phone system
A virtual number on your cell. If you are a solo owner, a one-user plan such as Unitel Voice Solo ($6.99 per month billed annually) or 800.com Startup gives you a separate business number without new hardware.
Your existing software. If your team already pays for Zoom Workplace, Zoom Phone can be added for $16 per user per month on annual billing.
Your wireless carrier. If you already have business lines with T-Mobile, ask for a bundle quote before buying a separate system.
Shared line only. If only one or two people answer the phone, an account-priced plan with unlimited users may cost less than per-seat pricing.

Frequently asked questions
What is the best phone system for a small business?
For most small businesses, a cloud phone system with unlimited domestic calling, an auto attendant and a mobile app is enough. Nextiva Core ($15 per user per month annually), Zoom Phone ($16) and Ooma Office Essentials ($19.95) cover those basics, as listed October 2026. Call-heavy sales or support teams should look at Aircall or Dialpad.
How much does a business phone system cost per month?
Among the providers we compared, listed prices run from $6.99 per month for a one-user plan to $75 per user per month for contact center tiers, as listed October 2026. Most small business plans fall between $15 and $50 per user per month on annual billing. Add taxes, activation fees and extra number fees to get the real total.
Is VoIP good enough for a business phone system?
Yes for most businesses, as long as your internet connection is reliable. Every provider on our list runs over the internet and offers mobile apps, so calls can fail over to your cell data if your office connection drops. Test call quality during a trial or refund window before porting your main number.
Can I keep my existing business phone number?
In most cases yes. Moving a number to a new provider is called porting, and cloud providers handle it as part of setup. Keep your old service active until the port completes so you do not miss calls.
Do I need desk phones?
No. Every pick on our list works through desktop and mobile apps. Ooma states that no hardware is required. Desk phones are optional and are bought separately if you want them.
What is the cheapest business phone service?
Unitel Voice Solo has the lowest listed price on our list at $6.99 per month billed annually or $9.99 monthly, as listed October 2026, with unlimited calling and texting and one toll-free or local number. It suits a solo owner, not a team that needs queues or CRM integrations.
Which business phone systems have a free trial?
Dialpad lists a 14-day free trial. Unitel Voice calls its first 30 days a risk-free trial with a full refund, and 800.com offers a 30-day money-back guarantee instead, and Aircall says it offers free access to test the platform. Phone.com offers a 30-day money-back guarantee on user fees. Nextiva, Zoom Phone, Ooma, Vonage and T-Mobile for Business did not publish a free trial on the pages we checked.
Is annual or monthly billing better?
Annual billing is cheaper, sometimes by half. Nextiva Engage is $25 per user annually and $50 monthly, and Aircall Professional is $50 annually and $67 monthly. Start month to month or use a trial if you are unsure, then switch to annual once you know the system fits.
What happens with 911 on a VoIP phone system?
Internet phone services route 911 using the address registered on your account, so keep each user's location current in the admin dashboard. Ask the provider how 911 works for remote and mobile app users before you go live.
Can I cancel a business phone contract early?
It depends on the provider and billing term. 800.com and Ooma list no long-term contract, and Nextiva says you can cancel anytime. On annual plans, ask what you owe if you leave early and how to cancel, before you sign.
