VoIP vs. Landline for Small Business: Which Is Cheaper in 2026?

If you typed “VoIP vs. landline, which is cheaper” into Google, you want a number, not a lecture. So here it is, broken down by what you actually pay each month, plus a real example with dollar figures and the mistakes that quietly add cost when businesses make the switch.

VoIP vs. Landline: the real monthly cost

A traditional landline (also called a POTS line) is billed per physical line. The line itself is usually $40–$60 per month, but the true cost is higher once you count desk-phone hardware, inside wiring, separate voicemail or auto-attendant add-ons, and the technician visit every time you move a phone or add a user. Many small businesses report copper lines creeping past $100 per line per month in 2026 as carriers raise prices on a network they’re winding down.

Hosted VoIP flips that model. You pay a flat per-user fee — generally $15–$35 per month — that already includes voicemail-to-email, an auto-attendant, call forwarding, mobile and desktop apps, and free internal calling across locations. There’s no hardware to buy if you use softphones, no maintenance contract, and changes happen in a web portal in seconds. Industry studies consistently find businesses cut their phone bill 30–50% when they move from landline to VoIP.

A real example: a 6-person Plano office

Take a small accounting office in Plano, Texas with six employees and two shared lines on copper. Their landline bill: 2 lines at ~$55 each, plus a $35 auto-attendant add-on, plus roughly $40/month amortized for occasional service calls — about $185 per month, and they still can’t take calls on their cell phones or text customers.

On hosted VoIP at $25 per user, six users come to $150 per month — and that includes mobile apps, texting, voicemail-to-email, and an auto-attendant at no extra charge. That’s $35/month less for far more capability, or about $420 saved in year one before you count the productivity gains. Scale that to a 15-person office and the annual gap easily clears $4,000.

Why landline prices keep climbing

The deeper reason VoIP keeps winning on price: the copper network behind landlines is being switched off. On March 26, 2026, the FCC adopted its Network and Services Modernization Order, giving carriers blanket authority to stop selling legacy copper service and put existing customers on a sunset track without prior federal approval. AT&T has said it will begin decommissioning copper in roughly 500 wire centers starting in mid-2026, with a full POTS sunset targeted by 2029 (see the FCC’s official fact sheet).

What that means for you: landline rates aren’t going to fall. Carriers have little incentive to invest in a network they’re retiring, so prices rise while the 90-day disconnection notice becomes the only thing standing between you and a forced migration. Moving to VoIP now is cheaper and lets you migrate on your own schedule instead of theirs.

Beyond price: reliability and features

Cost is the headline, but it isn’t the only reason the math favors VoIP. A landline does one thing — voice on a desk phone. A VoIP line gives every user a number that rings on their desk, laptop, and cell phone, plus business texting, call recording, and automatic failover. The one real dependency is internet: VoIP needs a stable connection, which is why many businesses pair it with a backup business internet link so phones keep working if the primary line drops.

Common mistakes when switching from landline to VoIP

The switch saves money, but a few avoidable errors eat into the savings:

• Skipping internet redundancy. VoIP rides your internet connection. If you don’t have a backup path, an outage takes your phones down with it. A low-cost 5G failover link removes that risk.
• Porting your number too late. Start the number port before you cancel the landline. Cancelling first can release the number and make it hard to recover.
• Over-buying hardware. You rarely need new desk phones — softphone apps on existing computers and cell phones work for most teams. Buy handsets only where you truly want them.
• Counting only the headline rate. Compare all-in costs. Landline quotes often omit maintenance, add-ons, and per-feature fees that VoIP bundles for free.

Frequently asked questions

Is VoIP always cheaper than a landline?

For the vast majority of small businesses, yes. The only edge cases are single-line setups in areas with no reliable internet, where a basic landline can occasionally compete on raw price — but even then it lacks the mobile and texting features VoIP includes.

Can I keep my existing phone number when I switch?

Yes. Number porting moves your current business number to VoIP, usually within a few business days. Start the port before cancelling your landline so the number isn’t released.

Will my phones stop working if the internet goes down?

Only if you have no backup. VoIP can automatically reroute calls to cell phones or another office during an outage, and a backup internet connection keeps desk phones online. This is why pairing VoIP with failover internet is a best practice.

Are landlines being discontinued?

The copper network behind traditional landlines is being retired. The FCC’s March 2026 order lets carriers stop selling copper service and sunset existing lines on accelerated timelines, with major carriers targeting full shutdown by 2029.

How much does a small business actually save with VoIP?

Most businesses cut their phone bill 30–50%. A 10-person office commonly saves $3,000–$6,000 per year versus comparable landline service, while gaining mobile apps, texting, and an auto-attendant at no extra cost.
