Before a contractor leaves, hand over active work, identify every workspace and connected service, then have the authorized owner close access and verify the result. A Slack account change is one part of offboarding; it does not prove that shared documents or other tools are closed.
This Slack offboarding checklist is for small teams finishing a normal contractor engagement. It is not an incident-response procedure. If you suspect misuse, follow your organization’s security process rather than waiting for a routine handover.
Start with a five-row handover record
| Record | Example to replace | Completion evidence |
|---|---|---|
| Person and workspace | Contractor A, client project workspace | Owner confirms the exact account |
| Open work | Two draft walkthroughs | Named teammate accepts ownership |
| Shared resources | Project folder and recording tool | Each service checked separately |
| Access end | Agreed engagement end time | Authorized administrator confirms closure |
| Follow-up | Outstanding invoice contact | Business contact route remains clear |
The examples above are a proposed operating template, not a product requirement. Keep the record in an existing approved document. Do not copy passwords, private messages, or unnecessary personal details into it.
What Slack deactivation actually establishes
Slack’s official guidance says an authorized owner or administrator can deactivate a member, with available actions depending on role. Deactivation blocks that account’s access, but it does not delete its profile information. Existing messages and files are not automatically erased by the account action. Review Slack’s guidance and your retention requirements before deciding what information must remain.
Do not use deactivation as a substitute for a deliberate records policy. Likewise, do not delete useful project records merely to make an offboarding checklist look complete.
Check these boundaries separately
- Workspace scope: identify all relevant workspaces, not just the one currently open.
- Project handover: record the current approved version, unfinished tasks, and the next owner before routine access ends.
- Other services: review file sharing, recording tools, project boards, and any access granted outside Slack in their own administration interfaces.
- Automation ownership: identify workflows that relied on the departing person; assign an authorized replacement and test the business task.
- Evidence: record who checked which service and when. A checked box without an observed result is still unverified.
When a paid offboarding tool is unnecessary
If departures are infrequent and one owner can check a short list of tools, an existing spreadsheet or document may be enough. Consider software only after repeated missed steps, unclear ownership, or a growing service inventory creates measurable work. First calculate actual administration time and unresolved access items; do not buy a subscription solely because a checklist exists.

Your next action
Create one handover record for the next departing contractor and assign one accountable owner. Close each service only through an authorized administrator, then mark the observed outcome.
