As most businesses are shaking off their old-fashioned PBX Systems in favour of hosted telecoms, the choice of VoIP providers has grown overwhelmingly. With this dramatic increase in VoIP providers, it’s certainly not easy to navigate your way through the best small business VoIP providers on the market. However, the important first step is to consider the specific requirements of your business – and then set out to discover which VoIP service provider can fulfil those needs.

In this little e-guide, our telecoms experts will reveal which features to look for in your next VoIP solution and compare some of the best providers out there. Let’s dive in!

What Should I Look for in a Small Business VoIP System?

If you’re a small business with a limited budget, you likely feel that investing in new technology is risky business. Will it actually pay off? To be honest, chances are that a VoIP solution is likely to be more affordable than whatever PBX or leased lines system you’re currently using. If you still need some convincing, however, we recommend that you take a look at this article covering the best benefits of VoIP for small businesses in 2019

Following this, we can now take a closer look at what you should consider when choosing the best VoIP solution for your small business. 

Firstly, you must consider whether your potential provider suits your business’ calling patterns. If you make a lot of international calls, it may be worth checking out the current rates for those countries you call most frequently. Are the rates offered by your VoIP vendor within reason? Or are they enough to break your budget? 

You must also consider that there is a variation amongst VoIP providers in voice quality. One provider might offer economical rates, but this may come at the expense of the clarity of phone calls. If your business depends on VoIP to deliver customer service, for example, the voice quality should clearly be something worth investing a bit extra in. 

As you can see, it’s absolutely imperative that you consider the specific requirements of your organisation before you start shopping for new VoIP solutions. The market is saturated with VoIP providers, of varying quality, and many of which disappear as quickly as they appear. We highly recommend that you take some time to learn which providers are recognised with solid reputations. In case you need some extra guidance, we have a thorough resource here on the best VoIP alternatives to Skype. Below, you’ll find a small selection of some of the best VoIP solutions for small enterprises.
