When operating a small business, communication is a major factor in the success of your small business. Here are some of the best communication apps to improve productivity within your company.

Microsoft Teams brings everything together in a shared workspace– letting you work from anywhere and making it easy for your team to chat, collaborate on files, and work with your favorite apps.

Fuze is a video conferencing app that hosts online meetings for all devices and operating systems, including iPads and tablets. It offers high-definition video and crisp audio, and it’s easy to set up and download.

Pushover sends push messages to any smartphone and organizes messages and notifications from your devices in one common space. You can send 7,500 messages each month for free and receive an unlimited amount of notifications on Android and iOS devices and desktops.

With Slack’s instant messaging platform, you can organize your team’s conversations into separate private or public channels or send a direct message. The app also makes it easy to drag, drop and share images, PDFs and other files right in the chat. It automatically indexes and archives any message, notification or file, and there’s no limit to how many users your business can add.

You can use Skype to video or voice call anyone in the world; get up to 25 people together on a call; transmit video, photos and files of any size; share your computer screen; and send text or voice messages. Skype can also be used on Amazon Alexa devices.
