Great tool but expensive at scale

We rolled out Slack to our entire 650-person organization over 6 months. Adoption has been strong – 89% of employees are active daily users. However, the cost at this scale is significant.

At $7.25/user/month for Pro, we’re spending over $56,000 annually on Slack alone. For a manufacturing company, that’s a substantial line item. We evaluated Microsoft Teams (included in our O365 subscription) but Slack’s superior user experience and integrations justified the premium for us.

The platform itself is excellent. Channel-based communication is intuitive, file sharing is seamless, and the mobile apps are reliable. Huddles replaced many of our scheduled meetings – quick audio conversations without the video meeting overhead.

Administration is straightforward. User provisioning through SCIM integrates with our Active Directory, and the analytics dashboard gives insights into adoption and usage patterns. Managing guest access for contractors is simple and secure.
