Ninja Number is a business phone line that works on your smartphone, managing your phone calls and texts while you work. It’s the only virtual phone system that lets you link up to 5 devices to your number, so if you can’t answer a call or text, someone on your team will back you up.

The magic doesn’t stop there. Ninja Number acts as your very own assistant, reminding you of missed calls and texts, automatically answering common questions from customers, transcribing voicemails to text, and so much more!

Ninja Number is the smartest technology out there. It uses a chatbot powered by artificial intelligence to help your business grow. It’s the Ninja power behind our Auto-Reply, seamless text conversation sharing between team members and voicemail transcription. Think your smartphone can do all that? Nope!

What can Ninja Number do for your business?

• Ninja Team — Don’t go it alone. When you sign up for Ninja Number, you can link up to 5 phones – no one else offers that! This way you’ve got your whole Ninja Team ready to answer calls, respond to voicemails and texts, and collaborate on conversations with customers, all within the same thread. All responses are tracked, so you’re always in the loop.

• Smart Auto-Reply — Weed out your call volume with artificial intelligence handling your most commonly asked questions. Customize your answers, and Ninja Number will automatically text back answers to those questions. If a customer’s questions become more complex, you or your Ninja Team can seamlessly hop into the text thread.

• Second phone line — Add a business line to your smartphone, so you always know what calls are coming in, and you can take your business with you wherever you go.

• Detailed Reporting — Ninja Number gives you more than 10 customizable reports based on your call history. We analyze your data to give you valuable insights on how to improve.

• Voicemail & Voicemail Transcription — Record your own greeting, or type one and have it transcribed into a voice of your choosing. Ninja Number automatically transcribes your messages to text, which you can reply to with a text message.

• Call Quality – Ninja Number uses your cellular connection, not WiFi, so all calls will have crystal clear quality, no data usage and you’re always connected.

• Call tracking — Mark calls according to their sales potential so you know at a glance what the most important calls are.

• Support — Having issues? We’ve got you covered.

• Text Messaging — Avoid phone tag by sending texts and connect with the younger market that prefers texting over calling.

• Push notifications — Get notified whenever you miss a call.

The most compete option

When I set out to choose an internet based business phone system I did my research, narrowed it down to 4 options and signed up for service. Two failed instantly, the other was not far behind but Ninja Number has proven to be an asset to my over business workflow. The app is consistently upgraded with features that provide me with targeted analytics to assist me in connecting with my customer more frequently and on their terms. The billing process is seamless, support is knowledgeable and so far I have not had any issues at all. At first I did not like the BOT setup system but it did exactly what it was designed to do in setting up my system in minutes.

Simply put, this simplified my life

This app is great! It drastically cut the cost of me having a separate phone for my business and it’s so easy to set up and use. It’s like having two phones in one, and it does a great job of keeping my business calls and my personal calls in different places so I don’t have to spend time figuring out who to call back if I miss a call. I’ll definitely be recommending this to everyone I know who has their own business!

I was surprised to see how much functionality the app actually had. I was able to set up my greeting in the app and link my phone right away and it was super easy. Still playing with it, but my favorite part so far is that I can see all of my unanswered calls and texts right on the home screen which keeps me more organized.

Awesome feedback! Thanks for sharing.
