Top 10 business phone apps

What’s that number calling?

Why are they calling?

And how should you answer?

When you’re taking business and personal calls on the same device, it’s easy to make a mistake.

The wrong greeting or slow response can send would-be customers to voicemail or even lose a sale.

That’s where business phone apps come in. They help you manage business calls on a single device.

They’re a simple solution to keep work and personal calls separate, letting you receive incoming calls on a dedicated business phone number without carrying around two phones.

The best platforms offer you the flexibility to use your personal phone, VoIP phone, or another internet-connected device like a laptop.

But not all options are created equal. At Nextiva, we’ve handled billions of phone calls for 100,000+ companies and helped countless users connect reliably on every device.

In short, we know what teams of all sizes need in a VoIP phone system.

We’ve reviewed the top 10 apps to help you pick the right solution for your business needs.

Short on time? Our pick is Nextiva. Most phone apps are too simplistic for a growing business or too complex for small teams. Nextiva includes the advanced features businesses need with an easy-to-understand interface and award-winning support that makes it accessible for companies of all sizes.

Our picks for business phone apps at a glance

A business app can help you manage separate work and personal numbers on the same device, as well as give you the tools you need for a professional phone presence.

Every incoming call is a potential sale, which is why it’s important to choose an app with the right features for your business. Integrated features help you streamline the platforms you use and can result in less app fatigue for your team.

A common business phone alternative is Google Voice, but it has limited features. The good news is that a Google Voice number can be later ported into a business phone service platform like Nextiva.

Verified reviewer, Capterra

Nextiva’s business phone software allows users to call, instant chat, or video conference with a single click. Users can move from the mobile app to the desktop app seamlessly, making it great for on-the-go calls and working from your desktop at home or in the office.
