What is the best virtual phone system for a small business in 2026?
For a team of one to ten, the right phone system answers the call, follows you to your cell, and does not bill you for seats you do not use.
You run a contracting business, a small practice, an agency or a shop. The phone rings while you are on a job or with a client, and the caller hangs up and tries the next name on Google. A virtual phone system fixes that without a desk phone or a closet full of hardware: one business number that rings on your cell and your laptop, a greeting, a short menu, voicemail sent to your inbox, and forwarding when nobody picks up.
The short answer: Quo (formerly OpenPhone) for most small teams, with a shared inbox and US and Canada calling included. Allo if missed calls are your real problem, since its AI receptionist comes with the entry plan. KrispCall for the lowest subscription, Grasshopper for a solo owner who just wants a second line, RingCentral if you need to grow into multi-site, and Aircall only if your day lives inside HubSpot or Pipedrive.
Running a sales team that dials all day? Our ranking of VoIP for small business covers that case. This page is about answering calls well.

How we compared and scored
A small business does not need a call center. It needs the phone answered, the call to follow the owner to their cell, and a clean greeting for anyone who calls after 6 p.m. Most "best of" lists rank by feature count and lead with whoever pays them most. They skip the three questions that hurt a small team: what you really pay at 1, 3 or 5 users, whether the auto attendant is on the plan you are buying, and how you leave with your number.
We compared official pricing pages, plan limits (seat minimums, included numbers, calling zones, texting fees) and hundreds of user reviews, especially the one-star ones. Scores for Allo, KrispCall and Aircall come from our full reviews. Scores for Quo and RingCentral match the ones already published in our other phone rankings. Grasshopper's score rests on its official pricing and the user feedback we read. Rank does not always follow score: Allo scores highest but is built first for teams that sell.
What we left out, and why. Google Voice requires a Google Workspace subscription, so it is an add-on rather than a standalone choice. Nextiva, Dialpad, Ooma and Vonage appear on many lists; we focused on tools whose entry pricing and plan limits we could read clearly for a team under ten. Ringover is popular in Europe but its public US pricing is not readable in a stable way in 2026, so we do not quote an amount.

Quo
Quo is the new name of OpenPhone, and it is built around simple setup. Calls, texts and voicemail land in a shared inbox, so whoever is free can answer. Starter costs $15 per user per month on annual billing ($19 monthly) and includes one number per user, with calling across the US and Canada under a fair-use policy. Extra numbers are $5 each.
The catch for a small business is the menu. Quo's phone menu (IVR) is only on Business and Scale. If you want "press 1 for scheduling, 2 for billing", budget Business at $23 per user annual ($33 monthly): $69 a month for three people instead of $45. CRM integrations (HubSpot, Salesforce, Pipedrive) also start on Business.
Texting customers costs extra in the US: carrier registration (10DLC) runs $19.50 one time plus $1.50 to $3 a month. Quo's AI agent, Sona, gives you 10 calls free, then $1 per call or bundles from $25 to $199 a month. Users who left Grasshopper often name Quo as where they landed.
Its limit: the low entry price is for teams without a menu. Read the tier before you pick it.
- Shared inbox for calls and texts
- US and Canada calling included
- AI agent with 10 free calls
- ✓Simple setup
- ✓Monthly billing available
- ✓Clear, public pricing
- ✗Phone menu only on Business and above
- ✗CRM integrations start on Business
- ✗10DLC texting fees on top
The default pick for a small team. Budget the Business plan if you need a phone menu.
Allo
Allo is a mobile-first business phone with one feature that matters a lot to a small business: an unlimited AI receptionist from the Starter plan. When nobody picks up, the AI answers, asks what the caller needs and sends you the summary. For a plumber on a job or a consultant in a meeting, a missed call becomes a written lead.
Per our full review, Starter is $18 per user per month on annual billing, $25 month to month. Business is $32 annual, $45 monthly. Three people on Starter cost $54 a month, $648 a year. Monthly billing lets you try it without a contract; move to annual once the team actually uses it.
Integrations are Allo's strongest score: HubSpot, Salesforce, Attio, Pipedrive, Zapier and Make connect natively. Business texting in the US requires a one-time $24 carrier registration (10DLC). There are still few public user reviews, which makes long-term reliability harder to judge.
Its limit: Allo is designed first for teams that sell and follow up. If you only need a greeting and forwarding, Quo or KrispCall cost less.
- Unlimited AI receptionist on Starter
- Native HubSpot, Pipedrive, Attio, Salesforce
- Monthly billing available
- ✓Turns missed calls into written leads
- ✓Highest score in this ranking
- ✓Strong CRM logging
- ✗Few public user reviews so far
- ✗$24 one-time 10DLC registration
- ✗More than you need for a simple greeting
The best fix if missed calls cost you jobs: the AI answers, you call back with context.
KrispCall
KrispCall has the lowest seat price here: Essential at $12 per user per month on annual billing, $15 monthly. Standard is $32 annual, $40 monthly. Three people on Essential pay $36 a month, $432 a year in subscriptions.
The fine print is the minutes. Calls draw on a prepaid balance, and extra numbers cost $5 to $10 each per month depending on the country. For a business that mostly takes inbound calls, the gap stays small. For a team that calls customers back all afternoon, the real bill can pass an unlimited plan like Quo's.
Our full review rates ease of use and integrations highly and value for money lower than the sticker price suggests, for that exact reason. Support is decent for the price.
Its limit: you need to watch the balance. Set a low-balance alert so calls do not stop on a busy Monday.
- Seats from $12 per user annual
- Monthly billing available
- Wide integration list
- ✓Lowest entry price on the list
- ✓No seat minimum
- ✓Quick setup
- ✗Minutes billed on top
- ✗Extra numbers billed monthly
- ✗Balance to monitor
Great for starting solo or with two people and few outbound calls. Past that, compare with an unlimited plan.
Grasshopper
Grasshopper has been selling virtual numbers to small businesses for years, and it still does one job well: a second, professional line. Plans start at $14 a month, with 20% off when you pay annually, and a 7-day trial that does not ask for a card.
For a solo owner who wants a business number separate from their personal one, that can be enough. Check the plan page for exactly what the entry tier includes before you commit.
Some users report slow support during outages, and some who outgrew it moved to Quo for its shared inbox and texting.
Its limit: a tool for one person. With two or three people answering, pick Quo or KrispCall instead.
- A second business line
- Annual billing 20% cheaper
- Trial without a credit card
- ✓Low entry price
- ✓Trial with no card
- ✓Well-known name
- ✗Some users report slow support in outages
- ✗Few details on the entry plan
- ✗Not built for teams
Fine for a solo second line. As soon as a second person answers, move to Quo.
RingCentral
RingCentral's RingEX is the most complete platform on this list. Core starts at $20 per user per month on annual billing ($30 monthly), with unlimited domestic calling. Advanced, at $25 annual, adds CRM integrations and multi-site management. Ultra, at $35, sits on top. Extra numbers cost $4.99.
For three people on Core, that is $60 a month on annual billing, $90 monthly. The monthly gap is wide: if you are not sure, the first months cost more than Quo's.
RingCentral scores high on features and integrations and lower on ease of use. Expect more settings, more menus and an admin console built for IT managers.
Its limit: it is more phone system than a 3-person business needs today. Pick it if growth is planned, not just hoped for.
- Unlimited domestic calling from Core
- Multi-site management on Advanced
- Three tiers to grow into
- ✓The deepest feature set here
- ✓Strong integrations
- ✓Grows with you
- ✗Steep monthly price versus annual
- ✗Heavier admin
- ✗Overkill for a simple greeting
The safe pick if you know you will grow. For today's three-person office, it is more than you need.
Aircall
Aircall's integrations are among the best in business phone systems: every call and voicemail lands on the customer record in HubSpot or Pipedrive without typing. For an agency or practice that manages clients in a CRM, that saves real time.
The problem for a small business is the minimum. Aircall requires 3 licenses. Essentials is $30 per license per month annual, so even alone you pay $90 a month, $1,080 a year. Professional is $50. Add-ons stack: Aircall AI at $9, Analytics+ at $15, $6 per extra number. There is no free plan, just a 7-day trial.
Our full review scores Aircall 3.2 out of 5, dragged down by value and support. User reviews repeatedly mention slow support, outbound calling charges they did not expect and billing after cancellation.
Its limit: built for teams that call and track clients, not for answering. If you only need a number, a greeting and forwarding, you overpay.
- HubSpot and Pipedrive call logging
- Mobile and desktop apps
- Detailed call analytics
- ✓Calls logged in the CRM automatically
- ✓Widely known tool
- ✓7-day trial
- ✗3-license minimum, $90/mo even solo
- ✗Paid add-ons pile up
- ✗Support often called slow
Only worth it if your CRM runs your day and at least three people take calls.
Three questions most lists never ask
"Starting at" prices mislead small teams more than large ones: at 1 or 3 users, a seat minimum or a missing menu doubles the bill. Here is how each ranked tool answers.
What you really pay at 1, 3 and 5 users
On annual billing. Solo: KrispCall $12 plus minutes, Quo $15, Allo $18, RingCentral $20, Aircall $90 because of the 3-license minimum. Three users: KrispCall $36, Quo $45 ($69 on Business with the menu), Allo $54, RingCentral $60, Aircall $90. Five users: KrispCall $60, Quo $75, Allo $90, RingCentral $100, Aircall $150. Add sales tax, regulatory fees and texting registration where it applies.
Is the auto attendant on your plan
Ask this first. Quo keeps its phone menu for Business and Scale. Allo handles inbound calls mainly through its AI receptionist, included on Starter. Before you sign, open the plan comparison and look for "IVR" or "auto attendant" on the exact tier you are buying, not the one above it.
How you leave, with your number
Your number is yours to port. Before signing, ask in writing for the contract length, the renewal notice and how porting out works. User reviews of several providers describe annual renewals that arrived without warning and support that went quiet at cancellation time. Port first, cancel second.
- Write your needs before any demo: number of people, menu or not, texting, international calls.
- Ask for a price at your exact headcount, seat minimum included.
- Confirm the auto attendant is on the plan you buy, not the next one.
- Pay monthly for the first months when the provider allows it.
- Put the renewal date and notice period in your calendar the day you sign.
- Test a call from your real workplace, on Wi-Fi and on cellular.
Switch to a virtual phone system without missing a call
Most bad experiences come from the switch, not the software: a number released too early, a menu that is too long, a weak connection. These six steps follow the mistakes users describe most often.
Map who answers what before you shop
PlanList the people who take calls, the hours you are open and what callers usually want. A two-person shop with one reason to call needs a greeting and forwarding. A practice with scheduling and billing needs a short menu.
That one page tells you which tier to buy, and stops a sales rep from upselling you.
- Time needed
- About 20 minutes
Collect your porting details first
NumberAsk your current carrier for your account number, the PIN on the line and a recent bill showing the service address. The new provider will need all three to move your number.
Check that the name and address match your carrier account exactly.
- You need
- Account number, PIN, bill
Never cancel before the port completes
NumberThis is the costliest mistake. If you cancel your old line before the transfer finishes, the number can be released and lost.
Keep the old service running until calls ring on the new system, then test from another phone before you cancel.
- Order
- Port, test, then cancel
Register for texting if you text customers
TextingUS carriers block or filter business texts sent from unregistered 10-digit numbers. Your provider handles the 10DLC registration and passes on the fee: $19.50 one time plus a monthly fee at Quo, $24 one time at Allo.
Start it on day one; approval is not instant.
- Quo
- $19.50 + $1.50 to $3/mo
Keep the menu to two or three options
GreetingCallers to a small business want a human. Two or three choices are enough: "press 1 to book, 2 for an existing job". Add an after-hours message with your hours and a voicemail box.
Forward to a cell after a few rings, not after thirty seconds of silence.
- Options
- 2 or 3
Check your connection before you cut over
QualityA virtual phone runs over the internet. One-star reviews often blame dropped calls or phones that do not ring, and the cause is frequently weak Wi-Fi or a misconfigured router.
During the trial, call from your office, your car and a job site. If a spot fails, set forwarding to your regular cell number.

Small business phone systems · FAQ
How much does a virtual phone system cost for a small business?
Expect roughly $12 to $35 per user per month, plus a few dollars per extra number. In our ranking, KrispCall Essential starts at $12 per user on annual billing (minutes extra), Quo Starter at $15, Allo Starter at $18 and RingCentral Core at $20. Watch for minimums: Aircall requires 3 licenses, so a solo owner still pays $90 a month.Can I keep my existing business number?
Yes. Moving a number between carriers is called porting, and all major providers support porting in. Ask your current carrier for the account number and PIN on the line, then start the port from the new provider's dashboard. Keep your old service active until calls ring on the new system; canceling first can cost you the number.What is 10DLC and why does my phone provider charge for it?
10DLC is the US registration that carriers require before a business can send text messages from a regular 10-digit number. Providers pass the fee on. Quo charges $19.50 one time plus $1.50 to $3 a month, and Allo's review lists a one-time $24 registration. If you never text customers, you can skip it.Do I need an auto attendant on day one?
Only if more than one person or department takes calls. A solo owner can live with a greeting, business hours and forwarding to a cell. Once you have two or three people, a short menu ("press 1 for sales, 2 for support") saves you from transferring every call. Check the tier: Quo includes its phone menu only on Business and Scale.Is Google Voice enough for a small business?
It can be for a very small team already paying for Google Workspace, since Google Voice requires a Workspace subscription. It is not a standalone app you can buy alone for business use. If your team is not on Workspace, a dedicated provider like Quo or KrispCall is usually simpler to set up.Annual or monthly billing: which should I pick?
Start monthly, then switch to annual once the team uses it. The annual discount is real (Quo Starter is $15 annual versus $19 monthly, RingCentral Core $20 versus $30), but a year-long commitment on a tool your team hates is the most expensive option. Put the renewal date in your calendar the day you sign.Will a virtual phone system work on my cell phone?
Yes, the tools in this ranking are built to ring on your cell, so your business number rings on your personal phone without a second SIM. Call quality depends on your connection: weak Wi-Fi is the most common cause of dropped calls in user reviews. Keep call forwarding to your regular cell number as a fallback.What happens to my number if I cancel?
Port it out before you cancel, never after. Once the account closes, the provider may release the number and you lose it. Read the exit terms before signing: some users report surprise annual renewals and support that stops answering at cancellation time.
