"How much does VoIP cost?" is the first question nearly every business owner asks me, and it is the one the industry answers worst. You get a price like $19.99 in large type, and then a first bill that looks nothing like it. This guide gives you the real ranges, shows you where the extra dollars come from, and answers the question people are often too embarrassed to ask out loud: what does a business phone number cost in the first place?

Local Business VoIP is the small-business site of Carolina Digital Phone, Inc., a local business phone service provider in Greensboro, North Carolina. We have sold hosted phone service since 2000, so I have a stake in this subject, and I will tell you what we charge further down. The market figures in this guide come from independent 2026 price surveys and government sources that I link as we go, so you can check every one.

How much does VoIP typically cost for a business?

Plan on $15 to $35 per user per month for most small offices, with the full market running from about $10 to $50 or more. Where you land depends less on the size of your company than on which features you need and how the provider packages them.

Those ranges line up with what independent reviewers report. Tech.co's 2026 pricing breakdown puts hosted business VoIP at around $10 to $30 per user per month when you use devices you already own. Two things move a quote within the range more than anything else. Annual prepayment usually earns a lower rate than paying month to month, and the per-user price often drops as you add users.

Here is what that works out to for a monthly budget, before equipment, add-ons, taxes, and fees:

How much is a business phone number?

Less than most people expect. On a business VoIP plan, one local phone number normally comes with each user at no extra charge. You are not buying the number outright. You are paying a small monthly amount to keep it assigned to you, and in most cases it is already folded into the per-user price.

Forbes Advisor reports that an add-on toll-free number typically costs $5 to $15 a month. The Federal Communications Commission explains that toll-free numbers are assigned first come, first served, which is why a memorable one can be hard to find.

The most valuable number you can have is usually the one already printed on your sign. The FCC's consumer guide on keeping your phone number when you change providers confirms that you can generally take it with you, including moving a cellphone number or a landline number to a VoIP service, and that your old company cannot hold it hostage over an unpaid balance. Our number porting timeline guide walks through how long it takes. If you are starting from scratch, see how to get a business phone number and what a business phone number is.

What one-time costs should you plan for?

Phones are the main one, and they are optional for many people. A hosted system has no control cabinet to buy, so the up-front cost is far lower than the phone systems many offices are replacing.

• Desk phones. Most office models cost about $75 to $300 each, and conference or video phones cost more. Some providers rent phones for a few dollars a month. Anyone who is comfortable using an app on a cellphone or computer needs no hardware at all.
• Setup and training. Many hosted providers charge nothing for a simple setup. Larger or more customized installations may carry a one-time fee. Ask what is included: number porting, programming your call flow, and training your staff.
• Network readiness. Voice needs a stable internet connection. A few offices need a better router, an extra network switch, or wiring to a desk that never had a network jack. Our network readiness guide covers what to check.
• Number porting. Often free. Some national providers charge a one-time fee per number, so ask.

What taxes and fees get added to a business VoIP bill?

Usually four kinds, and together they are the main reason a first bill does not match the advertised price. None of them is a scam. The problem is that most quotes leave them off.

• Federal Universal Service Fund. Phone companies pay into this fund and most pass the cost through. The FCC resets the contribution factor every quarter. For October through December 2026 it is 42.0 percent, the highest it has ever been. It applies only to the interstate and international share of your voice service, not to your whole bill, but it still adds up.
• State 911 charge. In North Carolina the 911 Board sets the charge at 55 cents per connection.
• Sales tax. North Carolina taxes telecommunications service at the state's combined general rate.
• Provider fees. Lines such as "regulatory recovery fee" or "compliance and administrative fee" are set by the provider, not by any government. They are legal, and they are also where price increases tend to hide.

We went through each of these line by line in transparent VoIP pricing and cost per user. The short version: ask every provider for the dollar amount of taxes and fees at your address, not a percentage and not "plus applicable taxes."

What does the bill look like for a 10-person office?

Here is a worked example. These are made-up round numbers chosen to show how a bill is built. They are not anyone's price list, including ours.

The advertised price was $25 per user. The real monthly cost is $33.35 per user, a third higher, and nothing unusual happened. Now add ten desk phones at $120 each, a one-time $1,200. Over the first year this office spends $5,202, which works out to $43.35 per user per month. In year two, with the phones paid for, it settles back to $33.35.

That gap between $25 and $43.35 is why two quotes with the same advertised price can differ by hundreds of dollars a year, and why a quote with a higher advertised price is sometimes the cheaper one.

What is the cheapest VoIP for a small business?

By sticker price, the cheapest VoIP providers advertise basic app-only plans at roughly $10 to $15 per user per month, almost always with annual prepayment. If you work alone and only need a second line on your cellphone, one of those plans may be all you need, and I will tell you so if you call.

For an office, the cheapest VoIP for small business is rarely the one with the lowest advertised rate. Three things change the math:

• Feature gating. The auto attendant, call recording, or texting you assumed was included turns out to live in the next tier up, for every user.
• Add-ons, taxes, and fees. As the example above shows, these can add a third or more to the advertised price.
• Your time. When calls stop ringing at 8:15 on a Monday morning, the cheapest provider is the one that answers its own phone. An hour in a support queue costs a small office more than the few dollars it saved that month.

We took the bargain plans apart in the real cost of the cheapest VoIP service and explained what "cheap" should mean in the cheapest VoIP phone service for business, without the trade-offs. Both are worth five minutes before you prepay a year of anything.

Is VoIP cheaper than a traditional business landline?

In most cases it is, and the gap widens with every line. The FCC's 2026 Urban Rate Survey found that the average urban rate for basic fixed voice service is $33.99 a month. That is one line with a dial tone, and in my experience business lines usually run higher. It does not include an auto attendant, voicemail to email, a mobile app, texting, or call routing, all of which come with a typical VoIP user at $15 to $35.

A traditional office also needs a line for every simultaneous call, plus a phone system in the closet with its own maintenance bill. With hosted VoIP you pay per person, and the system itself is the provider's responsibility.

There is also a deadline to consider. The big carriers are retiring the copper network that old business lines run on, and the price of staying on it tends to go one direction. We explained what is happening in the copper line sunset, and Carolina Digital Phone has the details on AT&T copper lines that may shut off after November 15, 2026.

What is the best VoIP phone system for small businesses?

The best VoIP phone system for a small business is the one that fits how your office answers the phone, at a price that matches the bill, from a company you can reach. I know that sounds like a dodge, so here is the test I would use if I were buying instead of selling.

1. It includes the features you will use without a tier jump. For most small offices that means an auto attendant, ring groups, voicemail to email, a mobile app, and texting from your business number.
2. The quote and the first bill match. If a provider cannot tell you the all-in number in writing, keep looking.
3. You can keep your numbers. Every one of them, including the fax line and the one on the alarm panel.
4. A person answers when you need help. Ask where the support team is and how you reach them. Then call that number before you buy.
5. The contract fits you. Know the term, the renewal terms, and what it costs to leave.

Lists of the top VoIP providers for small business tend to rank large national brands by feature count. Those are capable products, and for a company with offices in five states they can be a fine fit. A ten-person office in Greensboro or Burlington is usually better served by a local business phone service provider that will program the system with you, show up if needed, and pick up when you call.

How do you get an exact price for your business?

Gather five things before you ask anyone for a quote. It takes about twenty minutes, and it turns a sales call into a simple comparison.

1. Count people, not phones

   List everyone who needs to make or answer calls, then note who needs a desk phone, who can use an app on a cellphone or computer, and which rooms need a shared phone. Most pricing is per user, so this number drives the quote.

2. List every phone number you use

   Write down your main number, direct numbers, fax lines, toll-free numbers, and the lines connected to alarms, elevators, or gate boxes. Mark the ones you want to keep so they can be moved to the new service.

3. Pull your last three phone bills

   Look at the total you actually paid, not the plan price. That total, including taxes, fees, and equipment rental, is the number any new quote has to beat.

4. Decide which features you will really use

   Pick the handful that matter, such as an auto attendant, call routing after hours, texting from your business number, call recording, or an AI receptionist. Skip the tier that charges for features nobody on your team will open.

5. Ask for the all-in monthly number in writing

   Request one figure that includes users, numbers, add-ons, equipment, taxes, and fees for your address, plus any one-time charges and the contract term. Compare providers on that figure and nothing else.

What does Carolina Digital Phone charge?

Our published pricing starts as low as $6 a month for a basic user and runs up to $32 a month for advanced users such as call center agents. Where your office lands depends on the mix of users, the number of locations, the features you need, and the term you choose. One, three, and five year commitments lower the monthly price. You can read the details on the Carolina Digital Phone pricing page.

A few things about how we quote:

• The monthly price on your quote is the price on your bill.
• Not everyone in your building needs the same kind of user. A warehouse phone or a break room phone should not cost what the front desk costs, and we price them accordingly.
• Nonprofits can ask about our Giving Back To The Community discount. See our page on phone service for nonprofits.
• You talk to people in North Carolina, before and after the sale. That has been true since 2000, and you can read our history and why businesses choose Carolina Digital Phone.

We are not the right answer for everybody. If you only need a second line on one cellphone, a basic app may serve you well, and I would rather tell you that than sell you more than you need. If you run an office where a missed call is a missed customer, you want a communications partner you can trust, and that is the work we do. Call (336) 544-4000 or request a callback, and we will give you a real number for your business.
