Considered Both Products
Fuze
Chose Fuze
Fuze was basically selected as our priority because of its seamless calling feature as compared to its competitors and the edge of simplifying the contextual features it is offering
Chose Fuze
8x8 Contact Center offers almost the same product and features.
Chose Fuze
Fuze proved to be a great solution and quite the improvement from our XO phone platform we moved away from. Fuze as a cloud solution allowed us to transition to a remote work environment very easily. Fuze reporting provided valuable insight into the call activity of sales …
Chose Fuze
Almost went with PanTerra and then discovered that Fuze has better infrastructure which allows for more reliability and uptime. RingCentral had too many apps and didn't feel centralized enough.
Chose Fuze
We have used smaller VoIP vendors and UCaaS, such as Ring Central, in the past. We chose Fuze, and it has been the right fit for us. The private VoIP vendor was not as expandable, and the services [were] just not there. Ring Central, though a capable product, was just not …
Chose Fuze
They are more expensive, with less product offerings, and a less dependable service.
Chose Fuze
We evaluated other projects like Skype for Business (now Teams), RingCentral, and Cisco alongside Fuze. What set Fuze aside for our organization was the amount of care and support they put into the proof of concept process to ensure that when we decided to start our test, it …
Chose Fuze
We have had several vendors try to get our phone business, and I have always given my opinion to management why we need to stay with Fuze. Customer service is wonderful and the support staff puts up with me and they are very helpful. We use another company to do our dialing …
Chose Fuze
Fuze was far more expensive and more complicated to set up. Our current platform took a few days to set up with SSO. Our contact center took a bit longer but works amazingly.
Chose Fuze
We did a short POC so we did not fully implement all functions with any of the providers before going with Fuze which was the cheapest.
Chose Fuze
I was not employed at my company at the time they selected Fuze. But in a general comparison to Vonage which I used at my last company, I think Fuze and Vonage are both good products.
Chose Fuze
Our company has used three different phone systems during my time. It began with an on-premises system from Interactive Intelligence, Inc. (I3), which is primarily a higher-end call-center product. Due to a business relationship, we were able to utilize what would have been …
Chose Fuze
Fuze is on par with its feature set of any cloud pbx provider I have seen.
Chose Fuze
When we were shopping, Fuze was able to give us the features we needed and a good price point.
Chose Fuze
Fuze does not stack up against NVM or Five9 at all. Fuze is such an inferior product to NVM. inContact and Serenova have great platforms as well but I haven't used them first hand yet. All these other plaforms plug into Salesforce well as Fuze does not. Fuze needs to …
Chose Fuze
Fuze has had consistent site availability as opposed to the selected provider. Their portals were down 90% of the time even before implementation.
Chose Fuze
They all have different usages, Fuze makes it feel like we are using a phone even if we use it from our laptops. We also wanted to have one centralized VOIP system, for example, we have Webex as our meeting system and Slack as our instant messaging system. Definitely much …
Chose Fuze
It's only the fact that we ported our phone numbers to Fuze that made us adopt the solution, for a question of price and support. Meetings, Chat and the mobile application have great potential for improvement.
Chose Fuze
We looked at RingCentral as well. They are a big name out there right now. It was actually a tough choice between the two. We had demos of all the software and understood how things worked. In the end, Fuze just made more sense for us. It has solved our problems and fits our …
Chose Fuze
Five9 is better as a contact center but can be used with Fuze if you want to combine it with a separate PBX type system. Avaya has more configuration options but is very costly when you need to setup or update hardware. Genesys gives you the best of both worlds, but the startup …
Slack
Chose Slack
Slack is far superior to Google Chat. There is much better organization and separation of groups/topics using channels and folders. I also believe that Slack is better than Teams. It has many integrations and functionality that make it similar, while also being more of a modern …
Chose Slack
Microsoft Teams, Discord and Google Chat
Chose Slack
Microsoft Teams is slightly more user friendly, due to it being connected to email. It connects to your calendar and is helpful to keep everything together. The notifications are a bit more helpful on Miro because it is live. I enjoy the ease of communication on Teams. It's …
Chose Slack
Slack is far superior to other interoffice communications I have used. It has more features for messaging like the ability to include emojis or react to messages. You can also edit and share messages between conversations. I'm not sure how other platforms have evolved but I …
Chose Slack
not much function as Slack offering. Public & Private Groups creation not available in Hangout
Chose Slack
I evaluated Skype for Business, Microsoft Teams and Google Chat. Slack stood out for its user friendly interface, powerful integrations and fast flexible communication. Microsoft teams felt more formal and complex, while Google chat lacked features. Slack best matched our …
Chose Slack
our team's current non-Microsoft(Google) tech stack, hard-coded into our workflow. It's infinitely more customizable than Teams, easily meeting our requirements. Additionally, Slack has unlimited external users, whereas Teams has limitation, so Slack is the obvious choice for …
Chose Slack
Slack works great with Salesforce and seems the most trendy. MS Teams has some more connectivity with the MS suite which is nice though and a bit more robust as a communication platform when using it for both chat and video. We use a combo of Zoom and Slack for internal …
Chose Slack
I have used Teams, Instagram, and WhatsApp for business, but Slack stands out for how organized and work focused it is. Unlike WhatsApp, which is more casual, or Instagram, which is not built for very professional and secure work chats, Slack keeps everything structured with …
Chose Slack
Trello is a task management tool platform that best complements Slack. Even though you can tag different team members to boards or specific tasks, Slack provides a more robust platform to communicate and share files, ideas, or issues about a task. And can be used as a general …
Chose Slack
I think obviously Slack is much much better than Google chat, in my previous organisation, we used to communicate everything via Google chat or email or Google meet, it was difficult to manage because those application combined had less options and features than Slack.
Chose Slack
I'm not a huge fan of Microsoft in general, I utilize Google and Slack more for my day to day.
Chose Slack

More Intuitive & Simpler Interface – Slack is easier to set up and navigate.
Faster Adoption – No need for complex Microsoft ecosystem integration.
Chose Slack
Slack has just been the best communications tool for our team. Slack integrations are the best, the fact that its multi-device functional and has great features like file sharing at a fast speed, screen sharing, quick and easy to use. I do not think we would ever consider and …
Chose Slack
Slack: It's easy to strike up a chat right away with one-click calls or huddles. By simply pressing the call button, both users are involved without the need to arrange a meeting. Microsoft Teams: With calendar invites, time slot choices, and numerous confirmation processes, …
Chose Slack
The UI is difficult to understand and also to find a particular chat it is difficult to search in Teams. Also Slack has cool features like Slack Workflows and To do lists and Slack Canvas which makes life more easier. Slack apps to integrate existing app and also I use Slack to …
Chose Slack
It is superior to other products in its ability to communicate quickly with other colleagues. I can collaborate and work on multiple projects with colleagues. It is just an amazing product to use at work. I like the ease of using the tool. It’s a much better product than teams …
Chose Slack
I absolutely hate Microsoft teams, I dislike Google chat, I really like Slack. The main reason for that rating boils down to UI and usability. At my company, we have to use teams and chat still when we are interacting with customers or certain other departments within the …
Chose Slack
Slack offers better chat then google chat for mobile devices AWS the Slack chat bot is more informative and efficient to use Azure dev ops and Slack are great to have side by side

Research Team Insight
Published

Fuze and Slack are two communication platforms with very different features, but with some areas of overlap. Both provide video conferencing and collaboration capabilities to certain extents. Fuze’s core identity is as a VoIP provider, with robust video conferencing, calling, and contact center capabilities. Based on reviewer demographics, it is more commonly used by midsized companies and enterprises. 

Slack’s core function is messaging and collaboration, with a wide range of integrations into the rest of businesses’ collaboration or development tools. The messaging platform is commonly used across business sizes. 

Features

Both Fuze and Slack have strong features to suit their target audiences but they serve very distinct needs. 

Fuze stands out for its robust calling and video conferencing capabilities. These functions are very robust, including high-quality screen sharing. It also offers more advanced call routing and contact center capabilities, which help manage inbound calls from clients, customers, and prospects. 

In contrast, Slack’s specialty is its role as a collaboration hub. It offers a superior messaging infrastructure that businesses can customize to their needs. It also has an immense range of prebuilt integrations, which allows businesses to centralize communications across multiple applications to the Slack dashboard. 

Limitations

While Fuze and Slack both excel in their respective niches, they are limited beyond their core roles. 

Fuze lacks any mature messaging functionality in the product. It’s support for collaboration functions beyond the actual meetings, such as file sharing, are also not as developed. There are also fewer prebuilt integrations available. This requires post-implementation developer work to integrate Fuze with businesses’ other technologies. 

In contrast, Slack’s face-to-face communications offering are very weak compared to its messaging capabilities. The platform’s video chatting feature is still immature at best, with lower quality and far fewer features available compared to true video conferencing and VoIP products. It’s also very reliant on third party integrations for its expanded range of capabilities. For instance, Slack lacks any scheduling capabilities for meetings or events, relying instead of integrations with apps like Google Calendar to deliver this ability. 

Pricing

Fuze’s pricing is a set amount per minute of communication, based on what product or service is being used and where the communication is going to. Calls in the U.S., Canada, much of western Europe, and East Asia range from $.02-$.40 per minute for outbound tolled rates and can be several times higher for toll-free rates. Fuze meetings that are “Dial-In” range from $.08-$.75/min, and dial-out is free. Call recordings cost $.02/min.

Slack offers 3 pricing packages for its platform. The Standard package, at $6.67/user/month when billed annually, is designed for SMBs and offers the core collaboration mechanisms, including group video calls and screen sharing. The Plus package, at $12.50/user/month when billed yearly, adds additional administrative tools and more guaranteed uptime. The Enterprise Grid plan, which is priced by quote from the vendor, adds unlimited workspaces, data loss prevention support, a dedicated customer success team, and HIPAA compliance.

Fuze has way more capability than we need for our small office so it might be best suited for large installations, call centers, and complex environments. Our office is small and our needs [are] minimal, so when we need support we are challenged to understand the support person due to our lack of technical sophistication. We sometimes feel like we should switch to a solution more geared for consumers or SOHO. Nevertheless, Fuze provides reliable service at [a] reasonable cost that meets our needs, and because support is rarely needed we are happy with them most of the time, i.e. when support isn't needed.

Slack is really effective for smaller teams to use as an internal communication platform. I think that it's still suitable even for companies of up to 500-1000 employees, but for larger teams it's less appropriate (or would require more aggressive organization, e.g. keeping channels protected and on an invite-only basis). It's really helpful for small team-to-small team communication too (like in our case where we create external channels to support POCs/business partnerships). It's not great for direct collaboration (e.g. it's hard to iterate on a project spec or a document together, directly in Slack) but it's well suited for conversational coordination, like planning meetings or asking informational questions.

Pros
  • Availability to use your work number anytime anywhere. Our recruiters make themselves available as much as they can. Being able to answer calls from their worklines while not in the office and make calls from their work numbers is a big deal.
  • Setting up new phones and numbers is very easy with their hub. I don't always have to go directly to their support team to setup new users. As long as I have the mac address of the phone and we have free numbers I can set a new user up in minutes.
  • Their support team is great as well. If I do need to get help with an issue their support team is quick to respond and very knowledgeable about their systems. Their team is also able to fix most support cases within the same day.

Cons
  • Desktop application stability and compatibility with certain hardware.
  • Better installation - Per-user and per-computer installs sometimes compete with one another and/or upgrades fail to install.
  • [The] desktop app is not best for touchscreen-enabled devices due to lack of ability to scroll through messages using a finger or stylus.

  • Undoubtedly Slack’s search function is powerful but sometimes it is difficult to find specific messages or files in very active channels with high message volumes. This needs an improvement.
  • I have experienced notification issues on my phone. I am not receiving notifications and have missed important updates as a result. I tried uninstalling and reinstalling the app, but the problem still persists.
  • The Business Plus plan does not include support for data loss prevention or offline backup providers.

Cost and support and the primary driving factors. The management team has been extremely responsive and assisting even with the obstacles and hurdles we experienced during implementation. We are still learning how best to manage the solution and comfort and pleasure with the solution will increase as our knowledge and skillsets improve.

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

Usability
For most user, Fuze is very user friendly and easy to get use to. When it comes to the admin portal, it can be a little more challenging. There are also a lot of feature you unable to do as an admin that would normally be accessible. This cause the admin to have to rely on Fuze support, which could delay the resolution of a problem

Reliability and Availability
We've had a few outages over the past year. More than other vendors I've used. They usually have outages fixed within an hour. The downside is they do not provide root cause of outages. If they do at takes them at least a month to get it to you

Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.

Performance
Since Fuze runs across multiple devices and platforms they really strived to make a lightweight interface that is optimized for phone calls, chat, and collaboration. The web client loads fast, the chat is always up-to-date, phone calls arrive on-time. The desktop client is the most feature rich and basically it just adds desktop sharing functionality as well as VoIP for calling, and the mobile client doesn't consume a lot of battery, and it stays running to get phone calls, chats, and can do meetings over Wifi, Cellular Data, or Cellular voice.

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.

Support Rating
Our experience with Fuze support has been overall very positive. Their technicians seem to be well trained and able to handle a variety of requests and issues without unnecessary delays or extensive troubleshooting. Fuze allows enough customer access to avoid the need to call support for every little issue but is ready to assist when issues are beyond our capabilities to resolve.

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.

In-Person Training
At many of our sites with more than 50 users, Fuze sent someone onsite to train. This worked surprisingly well, as the trainer allowed the users to set the pace and answered TONS of questions. Fuze has a very streamlined training process, their staff is very professional, very knowledgeable and very engaging.

Online Training
Fuze has vast amounts of training videos and guides on how to use its products and services. There are literally endless-hours of training and I often point end-users to a particular video which addresses the specific needs of the user, for example: how to check voicemail. Or, how to share your desktop, etc.

Implementation Rating
Personally, I didn't have any trouble getting started with Fuze. It was installed on my computer on my first day and I was good to go! Little to no hiccups. I was not with the company when they first adapted Fuze so I can not speak to the implementation as a whole.

Alternatives Considered
We have had several vendors try to get our phone business, and I have always given my opinion to management why we need to stay with Fuze. Customer service is wonderful and the support staff puts up with me and they are very helpful. We use another company to do our dialing campaigns. Not sure why, but I think the reason was Fuze didn't offer that service. Fuze from the beginning appealed to our business due to the fact that it seemed so easy to use and manage.

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.
Read full review
Scalability
Fuze does have scalability limits but most of that is how many end-points they can put on a virtual PBX, or VCX as they call them, I THINK its limit is somewhere between 2,000 and 5,000, but we've not had issues with that because we have put users into various VCXs some by location, some by department or function. Either way, we have 7,000 currently deployed, and are going to end up with over 15,000 when we are done, Fuze is VERY scalable.

Return on Investment
  • We receive constant negative feedback from mangers about the system not functioning correctly. (This is mainly due to lack of support from Fuze)
  • This has had a positive impact in that the system is cheaper and we are missing less calls due to the functionality of the system.
