Cheapest VoIP phone service for small business

The cheapest VoIP phone service for a small business in August 2026 is Google Voice Starter at $10 per user per month, but it caps at 10 users and has no auto attendant and no ring groups, so it is only cheap if one person answers the phone, and for a team it needs a Google Workspace licence per user on top. Among plans that can serve a team, five providers tie at $15 per user: Dialpad, Nextiva, Phone.com, Phoner and Quo. That $15 is the annual rate at all five. Ask to pay monthly and the same five run from $18 to $27.

Every comparison in this category ranks providers on the entry price, and the entry price is the least reliable number on the page. It is quoted on an annual commitment, it usually belongs to a plan that cannot route a call to a second person, and at one provider it sits on top of a three-license minimum that nobody puts in the headline.

So here is the same market priced three ways: the published entry rate, the rate you actually pay if you decline the twelve-month commitment, and the rate for the cheapest plan that can ring a team. The ranking is different every time.

Cheapest VoIP phone service by published entry price

Read at each provider's own pricing page in August 2026, lowest first. These are the annual rates except where a provider does not sell an annual plan.

Zoom Phone is missing from that table on purpose. Zoom publishes Zoom Phone plan names and features but does not render dollar figures into its pricing page markup, so we could not verify a current per-user rate at source. Vonage and 8x8 returned no readable pricing on any route we tried. We would rather leave a provider out than print a number we could not check.

What is the cheapest VoIP phone service if you will not sign for a year?

This is the question that reorders the list, and almost nobody asks it. Six of the ten providers above quote two prices: a lower one if you commit to twelve months and a higher one if you do not. Two more will not sell a monthly plan at any price.

Dialpad, Nextiva, Phone.com, Phoner and Quo all advertise $15. On a monthly plan those five run from $18 to $27, a 50 percent spread, and Dialpad moves from tied cheapest to second most expensive in the whole table. Nothing about the products changed between the two tables. The only thing that changed is whether the buyer is willing to commit to twelve months.

Whether that premium is worth paying is a real decision rather than an obvious one. A twelve-month commitment on a $15 seat saves $48 a year per user against Phoner's monthly rate and $144 a year against Dialpad's. If you are confident about the provider and your headcount, take it. If you are replacing a system you have never used, or you hire in waves, the flexibility is frequently worth more than the discount. A commitment like that is recurring vendor spend like any other, and if approvals for those currently live in somebody's inbox, running them through a proper purchase order approval flow is a cheap thing to fix at the same time.

The cheapest plan that can ring more than one person

Here is the trap underneath every cheap VoIP ranking. A business phone service that cannot route a call to a team is a phone number with an app on it. If two or more people answer the phone, the entry tier is frequently not the plan you can actually buy.

Four providers put an automated attendant on their entry plan, which is the exception rather than the rule: Nextiva Core at $15, Phone.com Basic at $15, Ooma Essentials at $19.95 and RingCentral Core at $20, though RingCentral's includes only on-demand recording alongside it. Google Voice does not: Starter at $10 has neither an auto attendant nor ring groups, and you need Standard at $20 plus a Workspace subscription. Quo puts phone menus and custom ring groups on Business at $23, not on its $15 Starter. Phoner puts the menu, ring groups, shared numbers, texting, recording and toll-free numbers together on Team at $29.

Grasshopper and Dialpad both publish that they have an automated attendant but neither states which tier carries it, and Nextiva, RingCentral and Grasshopper do not publish the tier placement of their ring groups or hunt groups either. Those are honest gaps in the public record rather than a criticism, but they mean you have to ask before you buy, and a price you have to ask for is not a price you can shop.

How much should a small business pay for VoIP?

For a US small business of two to twenty people, budget $15 to $30 per user per month for the plan, then add roughly 27 percent of the service charge for Universal Service contributions, $0.20 to $3.00 per line per month for E911, and any regulatory recovery fee your provider charges. That last one is the provider's own charge rather than a government tax, whatever it is named on the invoice.

The Universal Service figure is worth getting right because the number repeated around this industry is wrong. The FCC set the fourth-quarter 2026 contribution factor at 0.42, but it applies only to interstate and international end-user revenue, and interconnected VoIP providers may use the 64.9 percent interim safe harbor to work out that share. The arithmetic is 42.0 percent of 64.9 percent, so realistic exposure is a little over a quarter of the service charge, not 42.0 percent of the bill. That factor is reset every quarter.

Is there a free VoIP phone service for business?

Not one you should run a business on. Free tiers in this category are consumer products, trials, or software whose license explicitly excludes commercial use, and none of them carry the things a business actually needs: a published number you own, E911 with a dispatchable address, number portability, and somebody to call when calls stop arriving. Zoiper 5's free tier, for example, is licensed for non-commercial use only. The realistic floor for a business line you can rely on is $10 to $15 a month.

What actually makes a cheap VoIP plan expensive

Four things, in rough order of how often they catch people out.

Seat minimums. A per-license price is not a bill. Aircall publishes $30 per license and requires three of them, so a two-person business pays $90 a month. Most providers here have no minimum, which is the difference between a price that scales down and one that only scales up.

Tier gating. Decide which two or three features you need before you shop, then price the cheapest tier at each provider that includes all of them. The ranking reorders. A provider $5 more expensive at entry can be cheaper in practice because the thing you need is included rather than sitting two tiers up.

Metered second bills. Toll-free minutes, international calling, extra numbers and texting are billed separately at nearly every provider. RingCentral's 100 toll-free minutes on Core are pooled across the entire account rather than per user, with overage at 3.9 cents a minute. Ooma includes 500 toll-free minutes per tier. Grasshopper charges $19.50 once plus $1.50 a month to switch texting on at all.

Hardware. If anyone wants a physical desk phone, budget from roughly $85 per handset, and more if the desk has no network drop at it. This is the cost that turns a $15 plan into a four-figure first month, and it is also the one you can most easily avoid by starting with the apps.

Who the cheapest VoIP phone service is right for

If you are one person who needs a business number so clients stop calling your personal cell, almost anything in the first table works and the differences between the $15 plans are small. Buy the cheapest one that will let you leave, and revisit the decision the day somebody else has to answer the phone.

If two or more people answer, skip the entry tiers and price the menu-and-ring-group plan at each provider. That is the real comparison, and it usually lands between $20 and $30 per user. The full shortlist, including the three providers we could not price at all, is on our VoIP providers comparison, and the whole invoice rather than the seat rate is broken down in our business phone system cost guide.

If your headcount changes quarterly, buy monthly. The discount for committing is 20 to 80 percent depending on the provider, but the cost of being locked into the wrong system for a year is larger than any of those numbers. What decides whether the money was well spent is not the seat price anyway: it is whether the IVR system in front of the line sorts callers properly and whether call routing software puts them through to the right person. And whichever provider you pick, porting your existing number across is free here.

Phoner is $15 per user per month billed yearly or $19 month to month on Starter, with the phone menu, ring groups, shared numbers, texting, recording and toll-free numbers on Team at $29. No seat minimum, no contract, no setup fee.
