Highlights

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. 

Likelihood to Recommend

Fuze

  • There are limitations on the size and scope of the auto attendant so it is not recommended for companies who have more than 3 menu options.
  • Testing of functionality and keeping data clean for management does not exist (I have spent 100's of hours cleaning up professional services).
  • Great for corporate environments with high bandwidth locations, not so great on slow bandwidth (T1/DSL).
  • Fuze Portal does not allow deleting of multiple menu's, call flows, schedules, or ring groups so it is labor intensive to manage.
  • A lot of data can be extrapolated from Discover, but takes work learning how to use it.

Slack

Slack is a great tool to facilitate communication in large and small enterprises alike. Having the ability to send quick messages to colleagues around the world without the formality of an email makes communication more efficient. The emojis and gifs also bring a bit of whimsy into the office which in turns makes for a more comfortable office atmosphere. For a remote workforce, this tool makes staying in touch and communicating much easier while providing a helpful social aspect, after all there is no water cooler to gather around. For smaller businesses and non-distributed teams, it is still a valuable tool to keep track of and share information but definitely not a necessity.

Pros

Fuze

  • 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.

Slack

  • Flexibility around notifications. Being part of a 1200+ employee company & a member of multiple channels & groups in Slack, it's fantastic being able to control that notifications I WANT to receive (and which I'd like to "mute," another helpful function).
  • The ability to create separate "channels" & groups. This has been key in making sure communication is organized & categorized in a way that makes sense. For example, we have separate channels for announcements, tech-related troubleshooting, different departments, etc.
  • Ease of use & just plain fun. With emojis, "reactions," and gifs built in, communicating can be quite fun :)

Cons

Fuze

  • Android and iOS apps do not always handle disruptions from other phone activities well. Inbound phone calls and changes to Bluetooth connections (earpiece to car, for example) can foul up an ongoing meeting.
  • We would love the ability to easily move calls between devices -- Software to desk phone, desk phone to mobile client, etc. Fuze has made some improvements in this area, but there are still a couple of missing pieces.
  • The Fuze Meetings module is still a bit behind the major players like WebEx, Zoom, etc., in features and general usability.
John Dennis | TrustRadius Reviewer

Slack

  • While their focus on continuous product improvement is admirable, the pace of change sometimes introduces bugs to existing features.
  • Some workspace administrative options require logging in to the workspace website -- it would be great to be able to manage all configuration directly from the desktop app.
  • Allow me to be petty for a moment: Why can't we have bigger emojis?

Likelihood to Renew

Fuze

1,000% will renew. For the price, for the features, for the support, for the implementation, for the ability to deploy to a new site, or a new company acquisitioned that has an older PBX, we can get them to Fuze with so little effort, dump the phones on their desk, and give them all the features and "WOW" that they would expect from a modern enterprise.

It is just an all around excellent product for a company with over 100 employees whom work in various locations around the country. We have remote workers, as well as people that work in the office every shift, so it makes it much easier to communicate with everybody in the simplest and fastest way.

Usability

Fuze

Fuze 7.3
Based on 10 answers
You have to rely on the Fuze app. Fuze needs to be able to work seamlessly in Salesforce to be able to compete with other vendors. Basically, they are great for UcaaS but less than desirable for CCaaS. It's like they are 20 years behind. Overall, Fuze is very easy to use and to get up and running. Not the best solution if you have multiple teams with complex IVRs

Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

Reliability and Availability

Fuze

Fuze 8.5
Based on 3 answers
Because the people who designed Fuze were Data-center people, they thought of availability first, there really isn't any excuse for telephony downtime, and they certainly do well with this. There has never been a total outage, just a few features sometimes have been offline while Fuze moves the service to other servers, NEVER calling, sometimes chat or physical phones (which can be fixed by rebooting them). The uptime on the Fuze systems is basically: Always up, always available.

Performance

Fuze

Fuze 8.0
Based on 3 answers
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.

Support Rating

I think it is improving but as I said previously there is a stress on the billing side of the business which gives a perhaps unfairly poor impression of support. The recent interaction that I have had with Support is definitely better and from my experience as good as it has been.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

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.

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

I am very well satisfied with the Fuze implementation at our company. It is really easy to set up. It's a straight up process and requires very minimal oversight. I will also like to say that the implementation was fairly quick. Also the UI is very easy to go around. You can easily find any feature in particular that you were searching for.

It always helps if you communicate to everyone in the organization how important it is to drop whatever other chat tools they are using and jump quickly to Slack. They will all fall in love with it.

Alternatives Considered

Fuze

Post deployment we're currently reviewing the other unified communications solutions as Fuze is expensive per user when compared to other options available. Fuze has an advantage due to its PBX capabilities however licensing for non-PBX users is considerably higher then other vendors.

Atlassian actually ended up shutting down HipChat and partnering with Slack, but these are areas in which I think Slack outperformed HipChat:
  • Better UX
  • Ability to edit messages once they've been sent
  • More functionalities and integrations with different tools
  • Ability to share channels with other organizations
  • Better mobile app
  • Dark mode

Scalability

Fuze

Fuze 7.0
Based on 3 answers
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

Fuze

  • 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.
Mikey Romero | TrustRadius Reviewer

Slack

  • I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work
  • Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool
  • We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.
