How To Add Someone On Slack From A Different Company

Slack is a widely-used communication application that facilitates teamwork and collaboration. Nonetheless, incorporating a member from an external company into your Slack workspace might pose some challenges. This guide will walk you through the procedure of adding an individual from another company to your Slack workspace.

Step 1: Create a Shared Channel

The first step is to create a shared channel in your Slack workspace. A shared channel allows members of two separate workspaces to communicate and collaborate in one place. To create a shared channel, click on the three horizontal lines in the top left corner of your screen and select “Create Channel.”

Step 2: Invite the User to Join the Shared Channel

Once you have created the shared channel, you can invite the user from a different company to join. To do this, click on the three dots in the top right corner of the shared channel and select “Invite People.” Enter the email address of the user you want to invite and click “Send Invitation.”

Step 3: Accept the Invitation

The user from the different company will receive an email with a link to join the shared channel. They will need to click on the link and accept the invitation to join the channel.

Step 4: Communicate and Collaborate in the Shared Channel

Once the user has accepted the invitation, they will be able to communicate and collaborate with your team in the shared channel. You can use the channel to share files, send messages, and work together on projects.


Adding someone from a different company to your Slack workspace is a simple process that involves creating a shared channel and inviting the user to join. By following these steps, you can easily collaborate with team members from other companies and streamline communication across your organization.
