London is one of the world’s biggest startup hubs, so it’s no surprise that more people are taking the step to starting a business there. It may be a thrilling venture, but it is equally expensive. And every single pound counts.

While it may not initially cross your mind as a business owner, choosing the right communication system from the start can make a huge financial difference when it comes to your monthly expenses, productivity and customer experience.

A lot of startup founders have turned to Voice over Internet Protocol (VoIP) as a cheaper, more reliable alternative to traditional phone systems. And given the impending landline switch-off next year, it’s a pretty smart move.

 

Why VoIP Is Ideal For Budget-Conscious Founders

 

Unlike traditional phone lines which use copper wiring, VoIP uses the Internet for both voice and video calling. The tricky thing with traditional phone systems is that they come with line rental fees, installation charges, hardware costs and monthly service fees that add up pretty quickly.

Since VoIP uses your Internet connection, you don’t need to fork out for expensive PBX hardware and you’ll find that UK calls are either very cheap or completely free even on the most basic plans.

Most startups also have the intention of scaling at some point and having a phone system that can do that with you hassle-free is certainly ideal.

VoIP allows you to do just that, you can start off with a few lines and add more on as you need or as you hire more team members. Generally, you can do it from your dashboard in a matter of minutes and without needing to pay for hardware.
