When to consider alternatives
Slack can be a strong option for teams that need chat, channels, and workflow apps, but procurement teams should still compare alternatives when seat count, implementation scope, required integrations, or renewal terms do not fit the business case.
| Alternative | Best fit | What to verify |
|---|---|---|
| Microsoft Teams | Microsoft 365-centered organizations | bundled and standalone collaboration pricing; confirm support, admin controls, data export, and onboarding scope. |
| Zoom | teams that prioritize meetings and webinars | host-based communications pricing; confirm support, admin controls, data export, and onboarding scope. |
Shortlist method
Start with must-have workflows, then score each vendor against pricing transparency, rollout effort, security controls, reporting needs, and exit options.
