External collaboration and Slack with shared channels icon

Guest accounts vs sharing a channel

All organisations need to work with external teams outside their walls, and you can bring that work into Slack with guest accounts and channels.

Guest accounts and channels

Guest accounts

These are great for working with someone who feels like a member of your organization but needs only limited access to Slack.

It’s important to note that guest accounts:

  • Are available for paid workspaces. Guests can belong to a single channel or multiple channels.
  • Can be invited to your workspace just like regular members via the invitations page.
  • Have icons by their profile photos: a triangle for single-channel guests and a square for multi-channel guests.

Channels shared with organizations

Separate organizations can work together in Slack, each from within their own Slack workspace.

The benefits of working with external organizations in channels include:

  • Working with external parties is as straightforward and fluid as with your own colleagues 
  • Each team has a common place to collaborate, loop in the right people on an as-needed basis, and build a collective repository of knowledge that anyone on either team can add to and reference
  • Each team can send messages, share files and access the channel history
  • Any member of the channel can also direct-message (DM) any other member in the channel, even if they’re from the other team

Should I create a guest account or use a channel?

If you’re working with…

  • An individual – Then use a guest account
  • A team – Then use a channel

More and more organizations are moving toward channels for the additional control and flexibility they provide—especially when collaborating with two or more people at other companies.
