How Much Does VoIP Cost for Small Businesses in NC?

If you're pricing out a business phone system in North Carolina right now, you've probably been hit with a dozen different numbers from a dozen different providers. One salesperson tells you "$19.99 per user" and hands you a quote for three times that. Another promises "free phones" and locks you into five years. Most of them never mention e911 fees, number porting, or the "regulatory recovery charge" that shows up on your first bill.

Bunn Communications has been installing business phones for North Carolina companies since 1985. This post is the plain-English answer we'd give a neighbor who asked: here's what VoIP actually costs, what you're actually paying for, and how to tell when someone's trying to slip something past you.

The short answer

Most small businesses in North Carolina — think 5 to 25 employees — should expect to pay somewhere between $20 and $40 per user per month for business VoIP service in 2026, plus a one-time cost for phones and installation. Bunn's own rate starts at $17.99 per seat, which is on the low end of that range and includes the core features most small businesses actually use.

A typical ten-person office budget breaks down roughly like this at market rates:

That's a wide range on purpose — the real number depends on a few things we'll break down below. But if someone quotes you a year-one number that's significantly under $4,000 for a ten-person office with real business phones, ask them to put every fee in writing. There's almost always something missing.

What you're actually paying for, per seat

That $20 to $40 monthly per-seat number covers the ongoing service — the thing that makes your phone ring. Here's what's included in a real business VoIP plan:

• Unlimited calling across the U.S. and Canada (some entry-level plans have a minute cap; most don't anymore)
• Voicemail with email-to-voicemail delivery
• Auto-attendant (the "Press 1 for Sales" menu you use to route calls)
• Call forwarding, hold music, call transfer, conference calling — the basics, all included
• Mobile app and desktop softphone — ring your office line on your cell phone when you're out
• Text messaging from your business number (a real feature now, not a luxury)
• Call recording (sometimes included, sometimes an add-on — ask)
• Basic analytics — how many calls, how long, who missed what

Price generally scales with features, not lines. A $22/user plan will handle 95% of what a small business needs. Jumping to a $40/user tier usually gets you things like CRM integration, advanced call queues, supervisor tools, and call center-grade reporting. If you're under 25 people, you almost certainly don't need the expensive tier.

The hardware cost is where surprises hide

Phones are a one-time expense, but it's the one that blows up the most budgets. A cheap residential cordless phone from Best Buy won't work on a business VoIP system. You need business-grade IP phones, and there are real quality differences.

Here are realistic market prices for the phones most small businesses end up buying. These reflect what a phone costs at a commercial distributor — not what any specific installer charges:

"Free phones" offers almost always mean one of three things: a multi-year contract with a termination fee that equals or exceeds the phone cost, refurbished equipment that's already two generations old, or a lease you'll still be paying after the phones have failed. Bunn doesn't offer free phones and doesn't recommend the providers who do. A good business phone should last 5 to 7 years — paying around $180 upfront for a solid Yealink beats paying $30/month for three years on a "free" one.

Installation — what you're paying a technician to do

A professional VoIP install for a small office usually costs between $500 and $1,500 as a one-time fee. Here's what actually happens during that install, so you can tell if the number is fair:

1. Network check. VoIP is only as good as the internet it runs on. A tech runs a bandwidth and quality test to confirm your router, switch, and internet can handle call traffic. Bad networks cause dropped calls, and no phone system fixes a bad network.
2. Router and switch configuration. Business VoIP needs Quality of Service (QoS) rules so calls don't fight your office Wi-Fi for bandwidth. If nobody configures this, your calls will cut out when someone downloads a big file.
3. Phone provisioning. Each phone gets its specific user account, extension, and feature set loaded onto it. With 10 phones, that's 10 individual configurations.
4. Auto-attendant and call flow setup. Building your menu tree ("Press 1 for billing, 2 for service…"), setting up hold music, configuring after-hours routing.
5. Number porting. Moving your existing phone numbers from your old carrier. This takes 2 to 4 weeks to fully complete and needs to be coordinated so your business doesn't miss calls during the cutover.
6. On-site training. Showing your team how to use the phones, the mobile app, voicemail, call transfer — the parts they'll actually touch every day.

If someone quotes you $99 to install a 10-person phone system, they're skipping half of that list. You'll end up paying for it later in either missed calls or a support headache.

The fees nobody mentions up front

This is the part of the conversation most salespeople would rather skip. Here are the line items that show up on real VoIP bills and what they actually are:

• E911 fee — federally required. Pays for emergency services to locate your address when someone calls 911 from a business line. Usually $1 to $3 per line per month.
• Regulatory recovery fee — a carrier's way of charging you for their FCC compliance costs. Usually a few dollars a month on the total bill. Legitimate but worth asking about.
• Federal USF (Universal Service Fund) fee — tax-like charge that funds rural telecom subsidies. Varies quarterly.
• State and local taxes — in NC, business phone service is taxable like most utilities. Typically adds 8-12% on top of the base bill.
• Toll-free minutes — if you have an 800 number, inbound calls usually cost you per-minute (~2¢/min). Light use, not a big deal. Heavy use, worth asking.
• International calling — "unlimited" almost always means U.S. and Canada. International is per-minute.

On a typical 10-user bill of $300/month base service, you'd expect to see maybe $40-60 in these extras. If you're seeing $150+ in unexplained fees, something is wrong.

Contracts versus month-to-month — what it really costs you to change your mind

This is the biggest hidden cost in the whole industry, and it's the one we think matters most. Most national VoIP providers lock you into 36- or 60-month contracts with "early termination fees" that can run into the thousands of dollars. They do this because the profit is in the later years — once you've paid off the hardware subsidy, you're just pure margin to them.

Month-to-month service usually costs $3-5 more per user per month. Over five years, that's roughly $1,800-3,000 more on a ten-person office than a locked contract. But if your business grows, shrinks, moves locations, or just wants to try a different provider, you can walk away without a fight. For most small businesses, the flexibility is worth it — especially if the phone system isn't working the way they were sold.

Questions to ask any VoIP provider before signing

If you're shopping around (and you should be), take this list with you:

1. "What's my total monthly bill after taxes and fees — the number I'll actually see?"
2. "Is there a contract? What's the termination fee if I need to leave?"
3. "Are the phones leased or owned? If leased, who pays if one breaks?"
4. "What's included in install, and what's extra?"
5. "Do you port numbers for free, and how long does porting take?"
6. "Who answers the phone when I need tech support — is it local?"
7. "How do you handle a power outage or internet outage?"
8. "What happens to my service if I move my office?"

If they stumble on any of those, you have your answer.
