One of the biggest perks of VoIP (voice over internet protocol)? It can be cheaper to make phone calls through your internet connection than to have a traditional landline business phone system―at least, if you choose the right VoIP provider. 

But with so many business VoIP providers, many of which use different pricing systems, how are you supposed to find the right affordable VoIP service for your company?

We’re here to help. We’ve rounded up our favorite cheap VoIP providers, and we’ll tell you what kinds of businesses they work best for.

8x8: Best overall cheap VoIP service

It’s no surprise that 8x8 tops our rankings of the best cheap VoIP service. After all, it’s been our pick for “Best Budget VoIP” for a while now (on our list of the best business VoIP providers).

That’s because 8x8 offers one of the cheapest plans out there (not quite the cheapest―that’s without forcing you to compromise on your VoIP service.

In fact, 8x8’s cheap Express plan gives you most of the features you could want. You’ll get unlimited calling in the United States and Canada (unlike the cheaper, which limits your minutes). You get not just voice, but also video calling and text messaging. You even get features like an auto attendant and smart call routing―features other providers often restrict to higher-tier plans.

And unlike other VoIP service providers that offer deeper discounts for more users, 8x8’s Express plan keeps things simple with the same per-user rate for everyone. That means you can start saving right away―not after you’ve expanded your team. 

Oh, and we should mention that 8x8 offers a generous one-month trial of its business phone service. If you’re not quite sure about 8x8, you can try it out for free.

To sum up, 8x8 isn’t quite the cheapest VoIP phone service out there, but it comes close―and it gives you way more than similarly priced competitors. And that’s why 8x8 is our favorite cheap business VoIP service.

The 8x8 Express plan comes at a low price, but it still offers unlimited calling and other essential business VoIP features. Best for limited use

If your business only needs the occasional VoIP call, is probably your most affordable option. offers the cheapest starting plan we’ve found for business VoIP―less than $10 per month with annual billing. And note that that’s not per-user or per-line pricing. You can have all the users and extensions you want with’s delightfully affordable Base Account plan. VoIP service plans

The catch? You get a limited number of minutes and a limited number of text messages with your plan (300 and 2,000 on the base plan, respectively). And yes, that’s split across however many users or lines you have with your plan. So if you have a dozen employees making phone calls every day, probably won’t work for you.

But for limited use, actually gives you a surprising amount of bang for not very much buck. The base plan gives you a free local or toll-free number for your business, and it comes with all sorts of features like an auto attendant, call handling rules, call groups (called call queues), and more. 

In other words, if you hate skimping on features but you’re fine skimping on calling minutes, you can get dirt-cheap business VoIP from

Best for limited use

If your business doesn’t make many calls (less than 300 minutes per month), offers all the extensions you need at one low, flat price.

Grasshopper: Lowest per-extension cost

Grasshopper doesn’t offer the cheapest plans out there―but once you do the math, it gives you the lowest price per extension we’ve found. 

See, Grasshopper uses a different pricing system than most service providers. It has three plans, and each gives you a specific number of phone numbers and extensions. With the Solo VoIP plan, for example, you get one number and three extensions. With the Partner plan, you get three numbers and six extensions.

Once you math that out, you’ll see that Grasshopper extensions cost between $7 and $9 each―cheaper than the pricing you’ll see from any per-extension VoIP providers. And if you choose the Small Business plan, you can get all the extensions you want for one monthly price. 

While we love Grasshopper’s low extension costs, we do need to point out that it doesn’t have all the best VoIP features. You do get helpful things like custom greetings, virtual fax, and custom schedules. But Grasshopper doesn’t have an auto attendant, calling groups, or other features you might want. So if there’s a VoIP feature you need, double-check that Grasshopper offers it before committing.

Still, with ultra-low per-extension pricing, Grasshopper is worth looking at.

Grasshopper’s unique pricing structure gives it the lowest per-extension cost we’ve found.

Google Voice: Best for solopreneurs

Do you run a one-person business? Then let us introduce you to free Google Voice.

Yep, we said free. Google Voice does offer paid business plans (and frankly, they’re not the best value we’ve seen). But it also offers a free personal plan that gives you one number and one phone line for one user. Of course, if you’re the only one taking calls, that’s all you need. And did we mention the free thing?

Now, a free Google Voice plan won’t get you all the fancy features you’d get with a true business phone service. Don’t expect an auto attendant, hold music, the ability to customize call handling rules, or anything like that. If those kinds of features matter, we suggest sticking with one of our other picks.

But you should expect free calling―you know, the most important VoIP feature―within the United States and Canada. (Texting too.) And you do get voicemail-to-text transcription, if you’re the kind of person who prefers reading to listening. For freelancers, online sellers, and other solopreneurs, those features might be enough.

While it may not be the most advanced service out there, Google Voice’s free VoIP plan can be a steal for solopreneurs.

If you need VoIP for just yourself, then you can’t beat the price of Google Voice’s free plan.

RingCentral: Best for bigger teams

The other providers on this list are great. But what if you have a big team with big needs? That’s where RingCentral comes in.

RingCentral, as you’ll quickly notice, is not the cheapest VoIP phone provider on this list. Not by a long shot. But when you’ve got a bigger team, many of the cheaper VoIP providers won’t have everything you want. RingCentral will―and it offers competitive pricing, plus discounts for more users.

With its cheapest plan, RingCentral gives you unlimited calling and text, along with team messaging. But by the time you upgrade to the Premium plan, you have loads of features―analytics, integrations, hot desking, big video meetings, and call center tools like whisper and barge, to name a few. In other words, pretty much everything your team could need.

For many large teams, those are features worth paying for. Otherwise, you just might find yourself struggling to make a cheaper VoIP service work―costing you lots of time and frustration.

So though it’s not quite as cheap as other VoIP service providers, bigger teams may want to pay a little more to get all RingCentral has to offer.

RingCentral offers lots of features bigger teams will love while still keeping its pricing competitive.

Honorable mentions


1-VoIP has pretty low starting plan costs (around $15 per extension), but it also uses a pay-per-minute model that can quickly add up. With a cost of $0.02 per minute, we’d suggest you just go with’s cheaper plan with included minutes instead.

That said, 1-VoIP does come with solid features, from an auto attendant to hours of operation. In other words, it’s not a bad option for businesses that won’t use lots of minutes―we’re just not sure it’s the very best either.


You can get Vonage’s starting plan for less than $15 per month, but only if you have at least 20 lines. Otherwise, you’ll pay closer to $20 per month. Either way, you do get unlimited calls, texts, and team messaging.

With its discounts for more users, Vonage can be a good choice for larger teams. Overall, we think RingCentral offers better features for similar prices. But Vonage does have plenty of integrations and helpful features. It’s not our favorite, but we think it’s still a good choice.


Dialpad’s Standard plan comes in at $15 per user―a very competitive price. It includes unlimited calling and texts, along with handy features like an auto-attendant and custom call routing rules.

As with other honorable mentions, Dialpad has a lot going for it. But given that 8x8 offers just as much for a slightly lower price, Dialpad remains an honorable mention rather than a top pick.


Nextiva isn’t nearly as cheap as some other providers on our list. You have to have more than 100 users to get its best pricing, which is still just a bit under $20 per user. 

But Nextiva does have one nice perk. In addition to a free toll-free number with your plan, you also get a number of toll-free minutes each month (1,500 with the cheapest plan). And that’s in addition to Nextiva’s unlimited voice and video calling. So if you need toll-free minutes, Nextiva might be surprisingly affordable.

Cheap business VoIP FAQ

Are there any free VoIP services?

Some VoIP providers do offer very basic free plans (like Google Voice), and plenty of providers offer free trials of their services. But in most cases, businesses with more than one or two employees will need a paid VoIP service.

How much does VoIP phone service cost?

Your VoIP service cost will depend on quite a few factors:

  • Your provider
  • Number of lines/users
  • Extra features you want
  • Your billing cycle (annual vs. monthly)
  • Whether you need to buy a business phone system

For basic, limited use, you could pay as little as $10 or so per month (with But if you’ve got dozens of users and you want advanced VoIP features, you’ll probably end up paying hundreds each month.

How do I choose the right VoIP service?

To choose the right VoIP service for your business, you can think about a few questions:

  • Does it fit with my budget? 
  • Does it work with any existing phones (both mobile phones and desk phones) my business uses?
  • How many users/extensions can this service support?
  • Does this service include all the VoIP features I want (like calling groups or auto attendant)?
  • Does the provider offer 24/7 customer support?
  • Can I test this service with a free trial? Does it have a money-back guarantee?

As you answer those questions, you should be able to narrow down your choices. And if you go with a provider that offers a free trial or a money-back guarantee, you can always try out your new VoIP service before committing.

The takeaway

If you’re tired of spending money on a traditional phone service, then switch to one of the VoIP providers above. They can save you money, make it easier to stay connected wherever you are, and offer lots of other features for your business.

All the providers above can work for your business, but we recommend 8x8 for most businesses in search of budget VoIP. Its phone service offers the best balance of price and features.

But no matter which VoIP provider you go with, we hope you enjoy your new, lower phone bill.
