We are a company of about 200 people and have no automation to help manage accounts. Everyone in the company uses Google Workspace, Slack, Notion and various teams use a variety of other services, as you'd expect (Pipedrive, Zendesk...)

Are there services that easily allow us automate creating and deletion of accounts when staff join/leave?

An example desired workflow would be:

We add a new user details in Google Workspace (or even in a Google Sheet), and add them to various groups. Notion and Slack accounts would automatically be created and they would be added to various groups based on their Google Workspace groups.

They would have calendar events created and welcome emails sent to them based on their groups also.

And when the GSuite user is removed, their access from Notion and Slack would also be removed.

Given every company faces the same problems, there must be a solution, right!? I am just not finding it very easy to find one -- or maybe I'm taking the completely wrong approach?
