Teams vs Slack – Which tool is ahead of the game?

Effective communication is crucial for any business. The ceaselessly expanding digital development eventuates in several useful tools and applications that can meet your team’s needs. Slack and Teams are among the major players in the intra-office communication space with unique structure that help coworkers to communicate efficiently in an organized platform.

Teams was launched as a competitor to Slack in March 2017 and while it also featured chatroom style, it was at first lacking a lot of the integrations and features that made Slack more preferred. However, after a year since release, Teams has become increasingly popular for businesses that have an Office 365 Business plan. In addition, Teams is also free with any Office 365 Business subscription.

Teams recently rolled out an update that pushed its popularity; integration with a host of different apps and a smart search bar. This new update has completely shifted the discussion as of what platform has the most potential business value.

Microsoft Teams

The previous lack of third-party integrations that proved to be a competitive problem, has now been resolved with a wide selection of integration with apps and services including Trello and SurveyMonkey. This has further made the software more of an intuitive communication option for any business. Users no longer have to take screenshots and upload to teams to share, and instead you can quickly attach content similarly to how you would add an emoji to a discussion. Teams also includes an improved search which allows you to insert results in chat as well as use slash commands.

Another great new feature is the ability to create conversation threads to avoid getting lost in the whirlwind of discussions about all different kinds of topics. Instead you can easily catch up by being able to respond to a message or topic in a thread under the original thought. Skype calling is also built into the platform where you can record, transcribe and save Skype meetings to the cloud. Plus, it’s integrated with the company’s voice assistant Cortana.


Slack is arguably the most popular collaboration tool out in the market right now. Many digital agencies, startups and other businesses are already using Slack. Founded in 2009, Slack emerged as a disruptor in the office communication market that was previously dominated by Skype. Slack’s past advantage over Teams lied in its easy third-party integrations and user-friendly design. It was one of the first of its kind to set the standard for office communication platforms that included both desktop and mobile version to stay connected wherever you may be. The long list of apps you can integrate still gives Slack a competitive edge, including its standard integration with Google Drive.

What do they have in common?

  • Quick Commands –  This allows you easily take certain actions and include status change, adding a team member, or simply adding a meme. You simply type “/” into the message bar and you get a full list of quick commands. With Teams you type “/” or “@” in the search bar to reveal the list.
  • The Search Bar – Both tools include a search bar at the top, that allows you to search for files or chats.
  • Conversation Threads – These help users understand which messages are part of which conversation and who is talking to who.
  • Channels – These are groups that are specific to different topics to help organised and focused on the topic of the channel.

What’s different?

  1. Third party applications –  Slack has over 800 third-party apps, and Teams has over 200 apps. However, Teams can also integrate with all Office 265 apps (Skype, Outlook, etc). This makes it the ultimate collab hub on top of the communication features. So if you’re already using 365 apps, Teams is best. But if you use Google, Slack might be better.
  2. Sharing and content –  Slack allows you to create and share documents through Google Drive, while Teams operates on the Office 365 package. You can therefore view, collaborate on, and edit files directly in Teams without having to leave the app which isn’t possible with Slack.
  3. Communication – With Slack you can video conference with up to 15 users at a time, but with Teams you can have up to 250 users in the most basic plan. So if you’re a startup, Slack will meet your needs. But If you work in a big organization you should look at Teams.
  4. Security –  Both provide security by being able to encrypt files, data and messages. Also, they both offer two-factor authentication, channel controls and data loss prevention. However, Teams has an admin center and is known to bundle security into every product which spreads across the different platforms.

The verdict?

Maybe you we’re hoping for a clear answer here, but truth is it varies form company to company. For example, if you’re currently using Google Drive, Slack might be the best bet. But if your office already has an enterprise license, Teams is a better bet. Slack has a great freemium version, but if you already have the Office bundle, Teams also comes for free. Both are also winners in terms of practicality and offer many similar great features.

So all in all, both are great options for communication in the office.  If you’re a startup or small business that is simply looking for a communication tool, Slack should solve your needs. However, if you’re looking for something more secure with more features (even in its freemium version), that also acts as a collaboraiton hub, Teams is your answer.

Soluno’s integraiton with Slack

By integrating Soluno with Slack, you do not have to switch between different programs. Make calls and send texts from Slack while your presence in the exchange appears directly in the interface. Our integration is called Slack Telephony and with it you can call directly from the tool. It all works via a so-called callback function. The call is initiated in Slack and then forwarded through Soluno’s exchange, which in turn calls you and your recipient. You can call people you have in your chat, contacts from your office phone system and external telephone numbers. The call can be started via simple commands or by clicking the Shortcuts button. The integraiton also allows Slack to know which line state and presence you have. For example, if you are in a conversation, a phone icon will appear next to your name in Slack. If you are, for example, referred to a meeting, are at lunch or on vacation, then icons for this will also appear in Slack.
