Summary: Slack is a team messaging app focused on chat, while Zoom One is a multichannel unified communications platform with video, chat, and an optional phone system. Since Slack focuses on messaging only, it’s cheaper than Zoom One–which has more channels and functionality.

Teams seeking a low-cost messaging and collaboration platform should pick Slack, and teams that want advanced video meetings should choose Zoom.

What is Slack?

Slack is a business messaging application that teams can use to communicate via chat, audio, and video. Available on desktop, mobile, and web browser, Slack enables team productivity with file sharing, task management and to-do checklists, and workflow automations. Team members can send DMs, create group channels, and initiate threads.

What is Zoom?

Zoom One is a unified communications platform emphasizing video and team chat, with the option for a native VoIP phone system. A strong team collaboration tool, it features video conferencing for up to 500 users with advanced features like breakout rooms, whiteboards, waiting rooms, live streaming, and more. Zoom team chat enables file sharing and one-click video meetings. The higher-tier plans include Zoom Phone–a complete cloud-based phone system with virtual numbers, call monitoring, and routing functionality.

Slack vs Zoom: Key Features


Dashboard, Interface, and Accessibility

Comparison: Zoom and Slack both have intuitive dashboards, available on desktop, web browser, and mobile. Slack’s interface is more user-friendly and easier to manage, but Zoom’s interface provides more functionality by unifying multiple channels, plus calendars.

Winner: Slack has a more user-friendly interface.


Slack Interface and Accessibility

  • Accessibility: The Slack app is accessible on desktop, web browser, and mobile apps
  • Dashboard and menu: We found Slack’s interface intuitive and easy to understand. The left-hand menu displays a user’s channels and 1:1 conversations. When you click on one of these, the center screen displays the active conversation and conversation history.
  • Notifications: New activity in 1:1 conversations or group chats pings the user in the left-hand menu, making it easy to stay on top of all activity
  • Connect with outside organizations: We loved the Slack Connect feature, which enables team members to add and invite users outside of the organization so that you can chat with them in Slack. Simply create a channel, email the invite code to any user, and they can join the Slack channel through their Slack interface.
  • Teammate availability: The Slack interface displays teammate availability via a green dot next to the user’s profile picture. Team members can also display an announcement next to their name. Our team members frequently let others know when they’re in a meeting or occupied for the day.
  • Slack Canvas: Every team channel has a Canvas–a section where users can organize and prioritize an ongoing list of needs and activities. Pin resources like files and images, create action item checklists, and post announcements.

Zoom Interface and Accessibility

  • Accessibility: The Zoom One app is available on desktop, browser, and mobile
  • Channels and interface: Zoom’s app interface has a top menu that organizes a user’s channels–Home, Mail, Calendar, Team Chat, Phone, Meetings, and Contacts. Once you click on a channel, the center screen and left-hand menu update to reflect the channel.
  • Dashboard and left-hand sidebar: Within each channel, the left-hand sidebar organizes basic functionality. View teammate availability, call and messaging activity, messaging groups and channels, reminders, and mentions from teammates.
  • Notifications: Any new activity triggers a notification in the sidebar and top menu
  • Folders: Organize files, chat conversations, and contacts into folders for easy access
  • Customizable: In the Settings tab, users can customize the items they want to permanently display atop their sidebar across all channels–Missed Calls, Contact Requests, Bookmarks, Reminders
  • External access: Invite users outside of your organization to join video meetings, phone calls, and chat groups


Team Chat and Messaging

Comparison: Slack and Zoom Phone both offer internal team chat and messaging, with file sharing and team channels. Both messaging interfaces include customizable formatting options. However, Slack goes above and beyond with built-in audio and video huddles that feature screen sharing.

Winner: Slack has more advanced team messaging features.


Slack Team Chat and Messaging Features

  • Integrations: Connect other apps to stay current on activities and messages across apps–from one dashboard. Our team personally connects Slack with Google Drive, Asana, and Salesforce.
  • Clips: Clips are a combination of video communication and messaging. With a “record” button built into the chat bar, users can record brief videos and send them via DMs and team channels. Users can also record audio and screen shares. When playing clips, view the transcript and adjust the playback speed.

Zoom Team Chat and Messaging Features

  • Team chat: The Zoom app supports 1:1 chat, group chats, and chat channels. Channels have a few extra features that 1:1 and group chats don’t have, such as the option for an instant video huddle.
  • Chat channels: Team chat channels are devoted to messaging groups and projects. Each channel receives a title, and the ability to designate private or public access. Channels also can share and store files, react to messages with emojis, and initiate video meetings with one click. Each channel can host up to 10,000 members.
  • Inviting users: Easily add team members to channels by typing their contact names. Internal team members can join your channel by searching for it and clicking Join. Invite external users to join by email.

  • Permissions: Account administrators can customize who creates channels and groups, who can send messages, and what permissions are available to users within each chat group

Phone System and Audio

Winner: Zoom offers a robust VoIP phone system.


Slack Audio Meetings

  • Team huddles: Initiate audio and video meetings from any DM or team channel, with one click. The left-hand menu’s headphones icon starts an audio huddle, with the option to turn video on. Any user in the group can hop in using the same button.
  • File sharing: Drop notes, files, Google Drive files, or links into team huddles
  • Any device accessibility: Access audio huddles on any device–mobile, web, or desktop

  • Virtual numbers: Purchase toll-free and local phone numbers from area codes around the country. If you’d like to keep your current business phone numbers, port them in to use with Zoom.

Pros and Cons

Slack Pros

  • User-friendly: The Slack interface is straightforward to use, even for users who aren’t tech-savvy
  • Tons of integrations: With over 2600 integrations, Slack likely integrates with most of the software apps you already use
  • Workflow automation: We found Slack’s Workflow Builder very easy to use, and we think it’s a very unique and valuable tool


Slack Cons

  • Team chat only: Slack works well for team chat and collaboration, with some video and audio. But you can’t use Slack for video or audio calls with external users.
  • Overwhelming notifications: Slack’s notifications keep us in the loop during the workday. But for users involved in multiple groups and channels, this leads to too many notifications that feel overwhelming.
  • Threads get lost: The way Slack’s messaging interface is structured, we found that threads sometimes get lost within channels and chats–leading to people missing your replies


Zoom Pros

  • Does it all: Especially with the Business Plus plan, we were impressed with Zoom’s unified communications diversity–video, phone, and chat
  • Best video on the market: In our opinion and experience, there’s no better video-conferencing platform than Zoom. It includes a great mix of collaborative, productive, and fun features.
  • Surprisingly advanced phone system: We were pleasantly surprised by how intuitive and capable Zoom’s phone system is. It includes advanced features like monitoring and queueing, added to the UCaaS offering for just $25 a month.


Zoom Cons

  • Too many features: While Zoom’s video meetings feature tons of features, we ended up not using about 75% of them. Some teams, like us, might feel that many of these features are unnecessary or distracting.
  • Bandwidth-dependent: In our experience, low bandwidth or a crowded internet connection majorly disrupted Zoom video meetings, leading to latency and glitchy video


Bottom Line

Slack is a low-cost messaging platform for internal communication. Zoom is a unified communications platform with video, team chat, and the option for a phone system.

If your team wants to enhance its communication system with team chat only, Slack is a better option. However, if you’re looking for a complete business communication app with multiple channels–it’s worth the extra cost for an app like Zoom.
