Maintaining an agile and scalable business communication system should rank high on any small business’ list of priorities. Voice over Internet Protocol (VoIP) can help. This technology powers most modern virtual communication and collaboration platforms, from Skype to Zoom.

In addition to voice and video calling, many of them also bundle other channels of communication, from live chat to email. Whether you run a large business, property management group, or small business, you can send text messages online and receive instant responses using a 2-way SMS text messaging platform that will change the way you communicate.
