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!

Thank you for the referrals! We designed our app so you could keep personal and business separate, so I'm glad you are seeing the benefit!

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.
