Suitable for small companies and stable solution
Pros and Cons
  • "Slack is a very stable product."
  • "The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM."

What needs improvement?

The reason we are considering other products is because of integration. It doesn't integrate with CRM or ERP. We worked with Microsoft Exchange and we worked with CyberArk. We have what we need, so we don't require Slack anymore. But I think it's a good product.

The reason is we are moving towards a new CRM, so we have a suitable solution to integrate with the new CRM. We have more specific needs now. Slack lacks in certain integration. 

For how long have I used the solution?

I have been using this solution for two years. 

What do I think about the stability of the solution?

Slack is a very stable product. However, with the free version, we only have limited message history access in the free version. But overall, it's a good product and a good solution.

What do I think about the scalability of the solution?

There are around ten end-users in my company using this solution. There is only one administrator for the solution.

How was the initial setup?

The initial setup was very easy.

Which other solutions did I evaluate?

Slack is a good product in its free version, but currently, we are integrating it with VM-sharing solutions like Dolibarr. We are also exploring other products similar to Slack. So, in about a month, we will be moving towards these new products and won't be using Slack anymore. 

However, until now, for the past two years, it has been a good product.

In the new CRM RFP, we plan to use Nextcloud. We also use SysTrack, but it's free. That's how our organization works. We have our own server, etcetera.

So, the only problem is we could not integrate it with our new solutions.

What other advice do I have?

I would definitely recommend Slack for small companies. For medium and large companies, I'm not sure. Maybe there are integrations available in the premium version of Slack. Otherwise, it is a very good product. 

Overall, I would rate the solution an eight out of ten .

Slack can be used right away also for small companies. I personally do not need tons of integrations. It is beneficial on its own. And it runs super stable.

A perfectly scalable tool that is easy to use and enables organizations to stay in contact with partners and create workspaces
Pros and Cons
  • "The product is easy to use."
  • "The integration with SharePoint doesn’t work properly."

What is our primary use case?

I use the solution mainly for chat. I go on spontaneous calls with colleagues. We also have channels for specific topics or customers and share workspaces with partners. Some of our partners also use Slack. So, we use shared workspaces and channels, which is a very good way to stay in contact with them.

What is most valuable?

The product is easy to use. It provides an easy way to stay in contact with partners and create workspaces. We can exchange information, have discussions, and search for information. We create channels for technical topics. It is quite useful to find answers because others in the team might have the answers to our questions.

What needs improvement?

The integration with SharePoint doesn’t work properly. It might be due to an access issue in the company. It is quite annoying. Sometimes, we cannot copy a shared document, but it might be because of the settings.

For how long have I used the solution?

I have been using the solution for four years.

What do I think about the stability of the solution?

The tool is super stable.

What do I think about the scalability of the solution?

The tool is perfectly scalable. The whole company uses it. We have around 1000 users. My colleagues at IBM have an even larger installation that works quite well.

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

Our organization has multiple tools, like Microsoft Teams, Zoom, and Webex. I can choose the one I like. I chose Slack because it is easy to use, and the spontaneous communications and channels are very useful. I prefer Slack for chats, channels, and exchanges with partners, but I prefer Teams or Zoom for web meetings, training, and webinars.

How was the initial setup?

The product is easy to set up. The solution is deployed on the cloud.

What other advice do I have?

I recommend people to start using the solution. And make sure you use the status feature and synchronize it with Outlook, so that people can see when you are busy. Overall, I rate the tool a ten out of ten.

Easy to use with an intuitive interface and the screen sharing works well
Pros and Cons
  • "The most valuable feature is the screen sharing, which works well."
  • "I would like the text in chat to be more customizable."

What is our primary use case?

We are using Slack for web conferencing. It is primarily for external communication with one of our suppliers.

What is most valuable?

The most valuable feature is the screen sharing, which works well.

This solution is freely available to almost everyone.

The tracking, integration tool, and voice calls are all good.

The user interface is intuitive for me.

What needs improvement?

There should be better integration between Slack and Office 365.

It should be easier to work collaboratively on files.

I would like the text in chat to be more customizable.

For how long have I used the solution?

I have been using Slack for a couple of months.

What do I think about the stability of the solution?

We have not experienced any problems with stability. We use it maybe once a week to contact one of our suppliers.

What do I think about the scalability of the solution?

As a user, I have not had problems with scalability. I am part of a small group that makes use of slack but that doesn't mean that it isn't widely used in the company.

How are customer service and technical support?

I have not been in contact with technical support.

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

We are using multiple web conferencing tools including Mircosoft Teams, Skype, and Slack.

I would say that the user interface in Slack is more intuitive than in Teams. One advantage to teams is that it is fully integrated into Office 365. I would say that collaborative working on files is better in teams. In our situation, the focus of Teams is internal, rather than with external partners.

What other advice do I have?

Overall, this is a good product and I can recommend it. It's easy to use and so far, it has been reliable.

I would rate this solution an eight out of ten.

Which deployment model are you using for this solution?

Real-time collaboration and simultaneous document editing increases team productivity
Pros and Cons
  • "Its intuitive design makes it easy to use and understand, hence we do not have a need to spend much on educating our teams."
  • "The only area of concern that I have is with the inability to preview received documents without having to download them first."

What is our primary use case?

I mainly use Slack as a collaborative chat, video and audio tool. I am able to set up a Slack room for different purposes and have all major stakeholders collaborate in real time. I enjoy the functionality on Slack that enables my team members to edit and collaborate on documents simultaneously.

How has it helped my organization?

Slack has helped to increase the productivity of my teams and organization. We have been able to cut down on subscription costs, reduce client delivery time, troubleshoot more effectively, and achieve positive results more easily. Its intuitive design makes it easy to use and understand, hence we do not have a need to spend much on educating our teams.

What is most valuable?

Chat, video, and call functionality has been awesome. The ease of setting up and integrating with other apps is seamless. Data consumption by the app is also at its barest minimum, helping to cut costs on the amount of data required to explore calls, video, or chat functionalities within the app.

What needs improvement?

I think the app is good enough, as I don't have any reason to comment negatively on it. The only area of concern that I have is with the inability to preview received documents without having to download them first. This could offer some sense of security and prevent downloading corrupted files or viruses.A "preview attachment/document" would suffice as an improvement, this will allow users decide if the need to download an attachment or not

For how long have I used the solution?

More than two years.

What do I think about the stability of the solution?

With respect to the stability, the app functions well, without glitches.

What do I think about the scalability of the solution?

This is a very scalable solution.

How are customer service and technical support?

Technical support for this solution has been very helpful.

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

I did not use another solution prior to this one.

How was the initial setup?

The initial setup is very easy and straightforward.

What about the implementation team?

The vendor handled our implementation and did a professional job.

What was our ROI?

Our ROI is approximately 40%.

Which other solutions did I evaluate?

I have evaluated both Microsoft Teams and Skype.

What other advice do I have?

This is a great app that has awesome functionality. A try will definitely be worth it.

Great for communication, easy to implement, and can expand as needed 
Pros and Cons
  • "The product has the ability to scale."
  • "We’d like it to have more capability for everyone to work on one doc in real time all at once."

What is our primary use case?

We're using Slack to communicate with other partners outside of our company. In most of the cases, it's for external communication.

What is most valuable?

Basically, it’s great for getting different kinds of groups with different partners - let's say one with the IT, one with the payment solution, into one place. It’s used just to communicate and nothing more than that. It's just a better solution to use instead of Skype or any other standard application.

It is easy to set up.

The solution is stable.

The product has the ability to scale.

What needs improvement?

The last time I tried to work with some other partners on the same document, we couldn't figure out a way to work on the same one. We actually have to have one person gather all the documents and then prepare one. It was actually taking way much longer than usual. We’d like it to have more capability for everyone to work on one doc in real time all at once.

For how long have I used the solution?

I’ve been using Slack for three or four years.

What do I think about the stability of the solution?

The solution is very stable. It doesn’t have bugs or glitches. It doesn’t crash or freeze. It’s reliable.

What do I think about the scalability of the solution?

I haven’t seen a lack of scalability. It seems like it would be easy to expand.

Most of our colleagues use the solution. We have around 100 people on the solution.

How are customer service and support?

I haven’t used technical support. I can’t speak to how helpful or responsive they are.

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

We’ve also used Skype.

How was the initial setup?

It's easy to set up. The IT team didn’t take that long to install it. There’s nothing wrong with that.

What's my experience with pricing, setup cost, and licensing?

I don’t deal with the licensing aspect of the solution.

What other advice do I have?

I'm not sure about the version I'm using. IT is taking responsibility for that.

I’d recommend the solution. It's easy to use. You just kind of need to use it more often just to get used to it and see how it works. It's nothing hard to figure out. It's easy to start.

I’d rate the solution an eight out of ten.

Easy to use and supports multiple chat channels
Pros and Cons
  • "The most valuable feature for me was the different channels."
  • "Slack does not have videoconferencing capabilities, which would have been nice."

What is our primary use case?

We used Slack for all of our internal communications during the COVID pandemic.

What is most valuable?

The most valuable feature for me was the different channels. You can make categories and then jump between different channels and groups.

It is really easy to use.

What needs improvement?

Slack does not have videoconferencing capabilities, which would have been nice. It would be helpful if they added this feature in the future.

The addition of more chat features such as sending GIFs and emoticons would be an improvement.

For how long have I used the solution?

We were using Slack for about three months.

What do I think about the stability of the solution?

The stability is good. It had never failed us.

What do I think about the scalability of the solution?

It is widely used in our organization, although I cannot say how many users in total. In our department, there are 14,000 employees.

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

We were using Slack and then during the COVID pandemic, we switched to Zoom. Now, we have installed Microsoft Teams and are working with it.

I think it would be excellent if they combined Slack and Zoom.

How was the initial setup?

The initial setup is easy. I had set something up wrong because I didn't make it private versus public, although I had not read anything about configuring it beforehand.

What's my experience with pricing, setup cost, and licensing?

My understanding is that we were using the free version. 

What other advice do I have?

My advice for anybody who is considering Slack is that it is a great tool. For us, it's difficult to talk with other departments, so this was the ideal solution. Overall, we really liked it, although it would have been nice to have videoconferencing support.

I would rate this solution a ten out of ten.

A user-friendly and affordable solution that enables seamless communication within teams
Pros and Cons
  • "The product is user-friendly."
  • "It is difficult to navigate the tool when I log in to two devices and start a video call."

What is our primary use case?

I use the solution for communicating with all the teams. We can communicate with people from other countries.

What is most valuable?

The product is user-friendly. It is easy to use. The colors, the menu, and the sidebar on the interface are good. Push notifications work well on mobile devices. It is what I need. It is helpful and useful for me. I am happy with the video calls.

What needs improvement?

It is difficult to navigate the tool when I log in to two devices and start a video call. If I log in to two devices, I get logged out of video calls.

For how long have I used the solution?

I have been using the solution for the last four months.

What do I think about the stability of the solution?

The product is stable.

What do I think about the scalability of the solution?

Almost ten to fifteen people in my organization are using the solution. The product is scalable.

How was the initial setup?

It is easy to set up the tool.

What's my experience with pricing, setup cost, and licensing?

The solution is cheap in my country.

What other advice do I have?

I have not used live streaming. I use the tool on both my desktop and on my mobile device. It works better than Trello. I would recommend the solution to others. Overall, I rate the product a nine out of ten.
