The product enables efficient communication and collaboration, but it crashes when used on the desktop
Pros and Cons
  • "Slack provides very fast communication."
  • "The product crashes when I use it on the desktop."

What is our primary use case?

We use the product in the office for communication. It's our main channel for any communication.

What is most valuable?

Slack provides very fast communication. The communication is sent directly to me, so I do not miss out on anything. The product provides various channels to communicate. A channel is like a team, where all communication regarding a team is sent. The product gives the flexibility of having many channels. Communication is isolated and sent to the right person at the right time. Slack has a voice messaging feature.

What needs improvement?

The product crashes when I use it on the desktop. The product must improve user experience. It would be quite interesting if Slack works with Microsoft Teams.

For how long have I used the solution?

I have been using the solution for six years.

Learn what your peers think about Slack Business - Enterprise. Get advice and tips from experienced pros sharing their opinions. Updated: May 2026.
902,270 professionals have used our research since 2012.

What do I think about the stability of the solution?

The product crashes sometimes. I've never understood what the problem is. It happens intermittently. I don't know what really makes it crash, but it happens once in a very long time.

What do I think about the scalability of the solution?

The solution is scalable. We are a huge team. We’re about 40 people. All of us use it seamlessly. It achieves our objective as a small team.

Which solution did I use previously and why did I switch?

In 2006, we used IP Messenger. It worked the same way but could be used only in the office. We didn't have any visibility of the communication outside the office. It did not have channels. It had many drawbacks, and Slack solved a lot of those problems.

How was the initial setup?

The solution is quite easy to set up. Anyone can easily set up the product, whether senior employees, junior employees, or professionals.

What other advice do I have?

I use Slack on my desktop. I have it on my phone too. All communications reach me as soon as they are sent, whether I’m in the office or outside. I don't look at the product for improvement. I appreciate what the product is doing. I'm not an administrator. I am a typical user. I joined the Slack channel because I was invited. I have access to Slack as a user, not as an administrator. I used IP Messenger as a software developer for a medium-sized organization in Kenya. We could share files. We could send text messages and all of it. We couldn’t use IP Messenger outside the office. It did not have channels. 

For people who need constant communication and don’t want to rely on emails, Slack is the right tool for them. We can work on the mobile phone to communicate on the go. As long as we have internet connectivity, it is secure. We can create as many channels as we like and collaborate. We can also do voice calls and send voice notes. Overall, I rate the product a seven out of ten.

A secure and widely-used solution that integrates easily and is helpful for internal and external communication
Pros and Cons
  • "You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value."
  • "It is good; it is one of the best ones out there, and when you're partnering with teams outside your organization, you can't really do without Slack because it becomes a necessity."
  • "I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom."
  • "Their notifications are generally not very prompt. There is a problem with their notification engine, and sometimes, I end up pressing on notifications."

What is our primary use case?

We use it for internal communication, and we also use it for external communication or customer relations.

What is most valuable?

You can create channels between teams internally and externally, which is great. There is a lot of security with Slack internal, which is what I value. 

You can very easily share large files through Slack. Integration is easy.

What needs improvement?

Their notifications are generally not very prompt. There is a problem with their notification engine, and sometimes, I end up pressing on notifications. There are a few bugs there. 

It also tends to lag sometimes. It gets slow.

I would like to be able to do live streaming on Slack. Slack allows Slack huddle where you can do a group call, but it is not very well-designed. I'm not sure if it is going very well, but live streaming is one thing that I would definitely love to see. When you use Zoom, I like how you can run webinars. If we could do that through Slack, it would become an all-integrated platform. I would also like to be able to schedule meetings using Slack, similar to Zoom.

I would like to see better connectivity between Slack and Gmail where Slack can prompt me for some of the things from my Gmail. For example, there can be a prompt such as "This person has been mailed, and you can contact him through Slack." 

It should have an automated translator. It would be helpful for interacting with people who are multilingual. For example, I speak English, but the other person might not understand English. There should be an automated translator inbuilt into Slack for such situations. Instagram has a similar feature where for a caption, you can click the See Translation button, and it does the translation for you. This is something that Slack could add.

For how long have I used the solution?

I have been using this solution for almost 18 months.

What do I think about the stability of the solution?

It is fairly stable.

What do I think about the scalability of the solution?

It can be scaled very easily. We have about 20 people who use this solution.

How are customer service and support?

I have not used their support so far.

How was the initial setup?

It was straightforward. It took one day.

What other advice do I have?

It is good. It is one of the best ones out there. You can definitely go for it. 

When you're partnering with teams outside your organization, you can't really do without Slack. It becomes a necessity. We chose this solution because Slack was the most widely used solution. A lot of companies that we partner with and a lot of our customers end up using Slack. So, for us to partner with them, we needed Slack.

I would rate it a nine out of ten. It is widely used, but they need to work on its features.

Which deployment model are you using for this solution?

A highly stable and affordable solution that can be used for team collaborations
Pros and Cons
  • "Tasks and team huddles are the most valuable features of Slack."

What is our primary use case?

I use Slack for team collaboration.

What is most valuable?

Tasks and team huddles are the most valuable features of Slack.

When I share any file with my colleagues, that file remains in Slack storage even after I delete the message. I need to manually delete them one by one. It would be better if Slack had a 'select all' option to delete all the files.

Slack is a stable solution.

I rate Slack ten out of ten for stability.

A collaboration tool where you can share files and to do a one-on-one or a group conversation
Pros and Cons
  • "Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat."
  • "When scaled on a large scale, the solution's cost becomes a matter of concern for organizations."

What is most valuable?

Slack is a collaboration tool where you can create specific topic-related channels and manage different threads on different talks so people can interact and maintain a chat. You can use the solution to share files and to do a one-on-one or a group conversation. It's a multilateral functional collaboration platform.

What needs improvement?

Slack is difficult to scale. When scaled on a large scale, the solution's cost becomes a matter of concern for organizations. It is a large project to migrate from Slack to Microsoft Teams or any other platform.

What do I think about the stability of the solution?

Slack is a pretty stable solution. I rate Slack an eight or nine out of ten for stability.

What do I think about the scalability of the solution?

Slack is a scalable solution, but not every organization can afford to maintain it. I rate Slack an eight out of ten for scalability.

How was the initial setup?

The solution’s initial setup is complex.

What other advice do I have?

It's up to the organization whether it wants to use Slack or not. Some people like the solution, while others don't.

Overall, I rate Slack eight out of ten.

A good solution for communication and file sharing, but it should add a feature to schedule meetings
Pros and Cons
  • "The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack."
  • "Slack should add a feature to schedule meetings."

What is our primary use case?

We use Slack for communication, file sharing, meetings, text messages, etc. Slack has been so helpful for us.

How has it helped my organization?

Slack has made communication much easier in our company. I can text someone in the company or send a message. I can also have an audio call with a couple of team members on the go without needing to start setting up calls on Zoom or Google Meet, or Microsoft Teams. I can have that voice or video call right away on Slack.

What is most valuable?

The huddle feature that allows you to get on a call with a colleague is one of the best features of Slack. You can call someone on the go with the huddle feature and save the time of having to set up Zoom calls or Google Meet.

What needs improvement?

Slack should add a feature to schedule meetings. Users should get notifications or prompts regarding the meeting time so they can attend that meeting.

Sometimes, when Slack is down, there is a delay in messages being delivered. Such delays also need to be improved in Slack.

For how long have I used the solution?

I have been using Slack for the past five years.

What do I think about the stability of the solution?

I rate Slack a six out of ten for stability.

What do I think about the scalability of the solution?

I rate Slack a seven out of ten for scalability.

How was the initial setup?

Slack’s initial setup was not difficult.

What other advice do I have?

I use the latest version of Slack. Slack is deployed on-cloud in our organization.

I highly recommend Slack for teams that want to communicate and collaborate. Slack can integrate with other apps like Google Calendar and Loom for voice and video recording. I recommend Slack for teams that want to scale and collaborate.

Overall, I rate Slack a seven out of ten.
