How do I cut Slack seat costs?
Reclaim inactive members (typically 20–25% of billed seats), downgrade Business+ to Pro if you don't need SSO, and convert single-channel guests instead of full seats where possible.
Details
Slack Business+ is $15/user/mo, Pro is $8.75/user/mo. If SSO and compliance exports are not in active use, downgrading saves $75/user/year. For a 100-person workspace that is $7,500/year.
Guest accounts are free for single-channel guests and $6.25/user/mo for multi-channel — significantly cheaper than a full seat for contractors, agencies, or clients who only participate in a few channels.
The most common Slack waste is billed but never-logged-in seats from hiring surges. Every quarter, pull the analytics CSV and reclaim anyone with 30+ days of inactivity.
