Considered Multiple Products
Mattermost
Chose Mattermost
Slack got very expensive and limited for the use we expected and also for the economic resources of the company. Mattermost allows custom modifications, and its interface is very similar to Slack, so we didn't need much time to adapt to it. We've been using Mattermost for 3 …
Chose Mattermost
Mattermost is very comparable to Slack. While Slack is more well-known and has a larger budget for advertising, Mattermost can hold its own. Slack probably has some additional integrations, but for what we were looking for (a quality communication tool) Mattermost was a great …
Chose Mattermost
Slack is excellent and has many of the same features as Mattermost. However, the cost if you have a larger group can be prohibitive. Mattermost is a better ROI per user, in our opinion. It also allows us to host it ourselves, which is more desirable for management by our MIS …
Chose Mattermost
As compare to Slack with this tool, Mattermost has introduced more convenience and features for collaboration. All updates come with new and advanced features and functions which always fascinate me and become the reason for using this efficient tool.
Chose Mattermost
We selected mattermost since we can control storage of our data. Slack is a great tool and offers more robust features compared to mattermost. However, the previously mentioned reason & the competitive pricing allowed us to stick with mattermost.
Chose Mattermost
Microsoft Teams feels quite clunky and the video chat is buggy. Slack is close but maybe not quite as feature-rich. Mattermost just feels like the right tool for a company my size ~1000+ users. No one has had any major issues with this tool and there haven't been any …
Chose Mattermost
Mattermost is very similar to Slack and has the advantage (in our case) of being entirely on-premises, and entirely free. The feature set is similar, and it has filled the original need that Slack was suggested as a solution for very well. Teams is potentially a better choice …
Chose Mattermost
Honestly iv just used these two but when it comes to customization, they don't come close to Mattermost. Slack and Teams are Less flexible, Not self hosted. Not Open source,etc I will also say that i noticed integration capabilities are very limited with teams and Slack and not …
Chose Mattermost
Slack is by far my personal favorite due to the age of the platform and the maturity of the features. Mattermost is a close 2nd-
Chose Mattermost
Unlike Slack and Discord, Mattermost is self-hosted and focused on security. I used Discord before for community management and much simpler and less secure operations. Slack is great, but the fact that is cloud based takes out a lot of its independence.
Chose Mattermost
In comparison to Slack, where Slack is strictly for internal communication, Mattermost actually has the format to display and not alter source code. Google Chat is also even more limited in comparison to Slack and Mattermost. If you collaborate on code every single day, then …
Chose Mattermost
They're very similar. I think it's really a matter of preference. Again, one of the things I like about Mattermost is that it's strictly for business (atleast for us) it's different from the more mainstream messaging apps used so we can kind of separate work vs personal messages.
Chose Mattermost
Much more expensive than most chat applications but you have more control over things by self-hosting. Your security team will be able to design a very secure place to store all your code, passwords, and internal details, but most companies will not require this. It would be …
Chose Mattermost
These products all required cloud connectivity and licensing that was a significant cost. Mattermost allowed us to pilot this among just the Ops team and then evangelize this to the other infrastructure team. This allowed us to slowly show the value of this software and expand …
Chose Mattermost
to reduce cost we shifted to Mattermost.
Chose Mattermost
Mattermost works better in that there aren’t constant updates and changes which can make finding past messages difficult. Mattermost also works better for channel creation and communication
Chose Mattermost
Mattermost provides a familiar user interface, fast performance, and a complete set of user collaboration tools and features - it stands out by providing a self-managed installation option for better integration with existing IT assets and more control over data storage. We …
Chose Mattermost
key selling points for us was that its open source and can be self hosted.
Chose Mattermost
First of all, we don't lose messages; we can see or search messages from any point in the past. Second, it offers to manage the whole product ourselves from hosting to serving users of our organisation. We feel that we have full control over data, managing users, …
Chose Mattermost
Skype is a light version when compared to Mattermost. Skype is easy to login (using username and password). Whereas, Mattermost login or setup or configuration is way different from Skype. We wanted to integrate with Jumpcloud for various reasons, so we have selected Mattermost …

Slack
Chose Slack
Much simpler and more pleasant to use than the alternatives.
Provides integrations, with external services, that work out of the box which is often an Achilles heel of competitive solutions.
Pricing is unfortunately not that great when compared to alternatives that come in a …
Chose Slack
The most convenient way to organize and follow thread (so any conversation) and a very large way to customize the workspace by individual (my workspace is organize in my way, but my colleague can have their own structure and organization). Also being able to add customized …
Chose Slack
Good User interface, feels easy to use
Easy to open a thread and have a discussion with rich text editing
Integrations are good, helps to check the status of many entities from single place

I used Mattermost on a full remote company and it perfectly suited our collaboration and communication culture. The company dealt with privileged and personal information of a huge data base of users, so it was a significant advantage for our need to comply with industry regulations.

This product is well suited for an organization that is focused on client services, project delivery, time tracking, expense reporting, and revenue recognition. From a pure project management perspective, this product is not as feature rich as say Microsoft Project Server. For organizations that are looking for detailed complex project plan and resource management (along with resource leveling, etc.), this is probably not the best suited product

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

Pros
Mattermost
  • Easy intergration to our main CRM (Monday.com)
  • I'm not techy myself but I have seen a lot of our previous integrations in Slack transferred over to Mattermost so that's fun
  • The desktop and phone app (android) works well enough. I haven't tried it on the Apple ecosystem yet.

  • Netsuite OpenAir PSA is highly configurable and has a large ecosystem of assets to work with.
  • Tasks are easily designed to automate processes in your business workflow.
  • OpenAir is designed in such a way that it can communicate and receive information from external systems without having to re-engineer your systems to make them work if you are following standard business practice.

  • The ability to easily tag a team member to urgently attend to a specific escalation.
  • Slack being user friendly and able to integrate easily with other platforms and apps.
  • How to easily open up different channels for different escalations and needs.
  • a safe direct messaging option.

Cons
Mattermost
  • Some of the features in paid plans could be free, however, they have much offered in free plan (self-hosted)

  • Compared to QuickArrow, setting up reports to reflect the data accurately seemed to require a bit more consultant time and collaboration. Getting the numbers correct is essential, so budget extra time for this iniative. We also learned that certain calculations can not be displayed in the executive dashboards. Ask these questions upfront to ensure your dashboards are complete for your needs (again, working backwards in the preparation stages).
  • Compared to QuickArrow, NetSuite OpenAir PSA falls short in the resource management capabilities. UI, flexibility, and scheduling options all could be improved. This is on their roadmap, timeline yet to be defined. Scheduling is vitally important to our company and this is THE area where we feel is the applications weakest. However, the application does provide everything critical to scheduling and provided the elements we needed in order to be successful. We altered our scheduling process accordingly.
  • During our System Administration 3 day online training, when a question was asked about detailed functionality, sometimes the trainer would share..."Yes, OpenAir has a configuration for that. Just inquire with your consultant and they can flip that flag in your instance." The responsibility for obtaining these special application configurations was placed on the System Admin [in training] to ask and to take notes. If your company needs the application to work a certain way, speak up and ask your OA consultant. There seems to be MANY flags that can be flipped in the background to allow for the system to meet your needs. My complaint is that these are not published, rather made available if one inquires.
  • OpenAir is able to generate invoices directly and we strongly encourage using this feature to keep everything housed under one application. However, this did not work for our organization and we leveraged a financial integration. A bit of a pioneer integrating with Softrax -- the integration works well, however is quite fragile. We do receive appropriate support when needed, but would prefer the integration to be a bit more stable. We recommend integrating with their stated supported financial systems, as staying the course will likely net a more stable integration.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

Mattermost has been an excellent tool for our business, allowing for a very cost-effective means of communicating, collaborating, and sharing project and business documentation and resources. The free community edition allows for simple installation on existing cloud server resources which results in significantly lower recurring costs compared to the competition

It all depends. We are still looking at moving our consultants to Oracle PAC, in order to get our financial systems in line (we use Oracle Financials currently). We are feeling a lot of pain with integration and segmented systems.

Ultimately,it depends on how much pain is felt there. OpenAir has given us a path to follow on from QuickArrow. I foresee either moving onto Oracle PAC by end of calendar, or staying on OpenAir.

OpenAir to Oracle integration is not easy. From a reporting and process perspective, there’s been pain from being in different systems

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

In this day and age I should not have to read a manual to understand a product. It should be intuitive to administrate and perform basic tasks. It feels like a ton of intelligence was poured into making OpenAir feature rich but no where near as much attention was given to the user experience.

My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

We have not had to contact support for Mattermost ever. All that we have needed has been available in the documentation or website. One of our DevOps team members set it up in a couple of hours. The whole team was using Mattermost that same day. No support needed.

As an admin, I've had more contact with OA support than most. I've found their response to tickets typically timely and helpful, however many of the responses to tickets are "we will file an enhancement request" and then I never hear about it again. So not terrible, but not a very fulfilling experience.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

We did a 3 day online remote course back in April. NetSuite prefers training to occur before migration. We went over the functionality of tool and three months later we migrated. Personally, I didn’t find it that beneficial. Certain parts of it were beneficial as they applied to me – talked a lot about invoicing capabilities that didn’t apply to me. They also have knowledge base / e-learning assets, but I haven’t referred to them

OpenAir accurately reflects changes in real-time as well as lends itself to see where a draw is at, when payment is expected and what percentage of the contract has been billed or approved to date. This helps with project billing and tracking as well as cash flow. Quickbooks lacks the ability to show progress draws, approved changes, and pending changes on a given project where OpenAir excels.

I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

  • It covers our requirements for time tracking and project/resource management better than the previous solution we used.
