We liked the modern look of Slack. We also liked the policy philosophy of the Slack team because it seemed to give a lot of attention to what its users always wanted to improve and although Skype was also a good alternative, we opted for Slack because of these factors.

I find that even though Slack is more expensive, it is way more simple, organized and straightforward than HipChat. Also, Slack has a much better performance on most mobile devices. Togther with that, HipChat has way less interations with other softwares than Slack, and these …

Here are the explanations for my preference of analysis Zendesk Suite to this end:

Power + Usability: Zendesk Suite has abundant omnichannel coverage, acceptable automation, and decent reporting but does not go all in to full-custom dev mode, so hangs nicely in the space of …

In my opinion, comparing with intercom Zendesk Suite is far superior in every customization, automation and escalation aspect

It prioritizes tickets from the urgent to the least urgent, and the best feature on Zendesk is that it illustrates when the other person is currently interacting with the ticket you are working on.

rt4 was a ticketing system I used previously. For the level of functionality we need which is B2B ticketing with multi-agent and multi-client tickets, it would be perfect.
Zendesk is a lot prettier than rt4 but not free. The sole reason we are still using Zendesk is that it was …
Chose Zendesk Suite
In my experience, I prefer Zendesk Support Suite over Salesforce. I feel that it's much more user friendly across the board. My biggest complaint is the user navigation frustrations that I run into with Salesforce. I feel like Zendesk Support Suite is much more intuitive on …
Chose Zendesk Suite
As long as I have worked at the company they have always used Zendesk support so I am not aware of other products other than zendesk support suite.

There is no comparison between SysAid and Zendesk. They occupy the same space in terms of what function they serve, but they could not be more different in terms of usability. SysAid does not allow you to use the back button in any browser, but instead forces you to use the UI …
Chose Zendesk Suite
I don't really use any other ticketing system with clients. We use GitHub which is a ticketing system, but not with our clients, only internally. Zendesk has been great and I do know other companies use it and love it!

At Onshape we have used this from the start but personally I have used a number of tools that were much more a part of the CRM packages like Sage and Zoho CRM and both are lacking in the API, User interface customization and tools that you can integrate. Other systems like …

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.

Being a customer support agent, I found it very good when it comes to send an email or call or chat- with the user. I can do all that from the one single platform which is so easy and time saving for you. It does not take much time to use this, We can chat- with the user and at the same time we can send an email to them as well.

  • UI/UX; mature macros and automations, slick and well thought out UI.
  • Reporting, reporting, reporting. With user, org, and ticket level tags, we can track every aspect of our ticket flow.
  • Extensibility; the app marketplace is a great resource for expanding functionality from the baseline offering.

Cons
Salesforce
  • 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

  • Is there a way for AEs and CSMs to be informed in a weekly summary of all their accounts and any tickets? Example: Disney submitted a ticket on XYZ. Google has an urgent issue on X still unresolved.
  • Is there a way for CSMs or AEs to have a Dashboard that's specific to their accounts instead of seeing all the tickets in the queue that are not relevant to them?

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.

Zendesk is an amazing tool for communicating with your customers easily. The communication tickets from sellers to us or from us to sellers are stored, and there are statuses used to make communication easy. We have internal conversations between departments, linked with useful software such as Zingtree, Talkdesk, and Webs.

Usability
Salesforce
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.

Pros: The agent interface is sleek, contemporary, and relatively easy to learn compared to many other enterprise tools. For common tasks, admins are given point-and-click options- adding fields, modifying workflows, constructing macros. The knowledge base (Guide) editor is easy to use for non-developers. Drawbacks: Once you move past the initial things - complex automations, reporting/analytics in Explore, and/or customizations integrating the API, it requires much more advanced training to use successfully. Navigating between the different modules (Support, Explore, Chat, Guide) can feel very disconnected; often you are reminded that it really is a "suite" of products brought together -not really one unified platform. If you're using multiple brands managing simultaneous support tickets, or heavily customizing workflows to meet your brand, you may run into a bit of struggle with usability. So: it's a lot more user friendly than the palaces (Salesforce Service Cloud, ServiceNow), but is not used as quickly or with as much streamlined flow as a product made for a small shop. So if you are looking for a great balance, this is a good option if you are a net new organization or an organization on their way to scaling from 15 - 50 employee. Expect some elbow grease from the admin team once learning, adapting, and working efficiently once you move past the basics with your support tickets and initial customizations.

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.

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 rarely need to contact their support team, but when we do they are responsive. However there have been notable times when communication between myself and the support rep was challenging despite me providing clear explanation of the issue, screenshots, and a thorough explanation of the goal we hope to achieve. It took several back and forth attempt, on a few occasions, to get resolution on an otherwise simple request

I was very satisfied. They have a free trial for 30 days and I recommend you do that and use it. It is very easy to get started with the basics and the build on over time.

The only thing technically complex was single sign-on and integration to Salesforce.com required some tweaks – otherwise setting up system was very easy

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.

We have extensive custom reports that tie up all aspects of our product and customer journeys. I've not found another product that allows me as much freedom as Zendesk Suite explore does, so far.
