VoIP vs Landline Cost for Small Business

“Is VoIP cheaper than a landline?” is the wrong first question if you only compare a round number you saw in an ad. A landline invoice is a stack of line charges, taxes, handset leases, extra-line fees, and features that used to look free because they were bundled into a contract you stopped reading. A cloud phone system invoice is usually a per-user card plus add-ons you can see. The honest comparison is line item against line item — not a made-up national average.

This guide is for US small businesses that still have copper, a key system, or a single POTS line and are looking at virtual phone service. It uses XI’s published pricing: $17 Starter, $20 Business, and $23 Business Plus per user / 30 days. It does not invent competitor list prices, “typical savings,” or how much a landline “usually” costs in your city.

What you are actually paying for on a landline

Pull last month’s carrier bill. You will usually see a monthly charge for the line itself, federal and state taxes and surcharges, directory or hunting features, and sometimes a lease or insurance line for the handset. If two people need to answer, you often pay for a second line or a key system that rings in two rooms. Long distance, if it is not unlimited, shows up as extra. None of those rows are “the phone” — they are the cost of keeping copper reachable.

Hardware is the other stack. A physical PBX or a multi-line key system has a purchase or lease, a maintenance visit when a handset dies, and a truck roll when you move offices. Those costs do not appear on the voice bill, so they get left out of “landline vs VoIP” tweets. Write them down anyway. If you own the boxes already, treat remaining maintenance and the next move as the relevant numbers, not the sunk purchase.

What a landline does not include is the rest of a modern customer conversation: two-way SMS on the same number, an app on a laptop, a browser softphone, and routing you can change without a technician. You can bolt those on with extra products. Each extra product is another invoice.

What XI publishes instead

XI Starter is $17 per user / 30 days. The card lists a ready-to-use calling system, one DID, unlimited calls in the US and Canada, mobile plus desktop apps, and standard support. That is cloud calling on a number you claim or port. You still need internet. You do not need a copper pair in the wall.

Business is $20 per user / 30 days and adds call recordings, voicemail transcripts, voicemail, a personalized greeting, and 24/7 support. Business Plus is $23 per user / 30 days for higher threshold limits. Scale is custom. Virtual receptionist, shared numbers, and API access are listed on Scale and as not included on the three public cards. Extra DIDs start at $1. Inbound SMS is $5/30 days. Call recording as an add-on is $1/user/30 days if you are not on Business.

Seat math is visible. One person on Starter is $17/30 days. Three people on Business is three times $20 unless you use the volume table printed on the pricing page for larger teams. Do not use unpublished coupon math from checkout in a cost comparison. Public marketing uses the cards only.

How to build a fair side-by-side

Make two columns. Left: every recurring row on the landline bill, plus estimated next hardware repair, plus any answering service or texting app you pay so the copper line can behave like a modern number. Right: XI seats times the card you actually need, plus the add-ons you will turn on (extra DID, inbound SMS, recording). Count people who answer the phone, not everyone on payroll.

Include time you currently spend forwarding the shop number to a cell when you leave, hunting for a voicemail on a dusty machine, and reprinting marketing when a line cannot move. Time is not a fake “ROI percentage.” It is still a cost. XI forwarding and routing are software settings. Moving offices is a new Wi-Fi network, not a new copper order.

Do not compare XI Starter to a full live answering service and call it a landline replacement. An answering greeting is the virtual receptionist, listed on Scale. Voicemail with transcripts is on Business. If you need a spoken menu on Starter, talk to sales instead of assuming it is in the $17 card.

Internet is a shared cost. You already pay for it if the shop has Wi-Fi or a card terminal. VoIP uses that path. If the connection is weak, fix the connection; a copper line will not make the rest of the business faster. XI does not publish a minimum megabit figure on this page, so this guide does not invent one.

What you gain that a landline does not itemize

The same DID can text after 10DLC registration. Callers can reach whoever is signed in, not whoever is standing next to the wall jack. Notes and history sit next to the thread in XI’s lightweight CRM. Compare pages such as XI vs RingCentral and XI vs Google Voice exist so you can check another cloud option the same way: published features and published XI prices, not a rumor about someone else’s invoice.

Local and toll-free numbers are on phone numbers, local numbers, and toll-free. A second area code is an extra DID from $1, not a second copper install. If you already tell customers a number, port it. If you are done with copper entirely, getting a business number without a landline is the companion how-to. This article is the cost worksheet, not the “how to get a DID” walkthrough.

Reliability is a separate question from price. Copper fails when the pair is cut. VoIP fails when internet fails. Many shops already have a phone hotspot they can fail over to. XI does not publish an uptime percentage here, so this guide will not invent one. Ask sales if you need a written description of failover for your site.

A three-seat example with only published numbers

Three people answer the phone. Starter is 3 × $17 = $51 / 30 days, one DID included, unlimited US/CA calling. If you want recordings and voicemail transcripts, Business is 3 × $20 = $60 / 30 days. Add inbound SMS at $5/30 days if guests text the same number. Add extra DIDs at from $1 each if you need a second local presence. That is the entire public arithmetic.

Put your landline total next to $51 or $60. If the copper bill is lower but you also pay a separate answering service, a separate SMS tool, and a cell used as overflow, add those. If the copper bill is higher, the gap is your comparison — not a statistic from a vendor deck. Taxes still apply on both sides; XI’s cards are the service prices on /pricing, not a tax quote.

Volume rows on the pricing page start at four Business users. If you are not in those bands, do not use them. Coupon prices on checkout are not public plan cards. This article will not quote them. International calling, if you need it, is a rates conversation — XI has a rates page rather than a hidden per-minute landline surprise. US/CA unlimited calling is what the public cards already list.

Switching without a silent week

Cost only matters if callers still reach you. Port the published number, keep the old line forwarded until the port completes, put seats on XI, and set no-answer routing before you cancel copper. The FAQ covers plans and porting. For the cutover checklist, use how to port your business phone number.
