Automation Depth
Slack Workflow Builder creates workflows triggered by messages, emoji reactions, forms, and schedules. Setup takes minutes for common patterns (standup collection, PTO requests, onboarding).
Teams + Power Automate provides deeper automation: 1,000+ connectors, desktop RPA for legacy apps, AI Builder for document processing, and process mining. The capabilities are broader but require navigating Power Automate separately.
Cost (50-Person Org, Communication + Automation)
Slack Pro: $437.50/month (automation included). Teams + Power Automate: $1,050/month. Slack saves $612.50/month (58%). However, M365 includes email, OneDrive, and SharePoint.
Best Fit
Choose Slack for diverse SaaS environments with quick no-code automation. Choose Teams for Microsoft 365-centric organizations needing Power Automate's deeper capabilities.
Editor's Note: We compared both for a 40-person company using Salesforce and Google Workspace. Slack Workflow Builder automated 3 workflows in 2 hours. Replicating them in Teams + Power Automate took 4 hours. For Microsoft-native companies, Teams is the natural choice. For mixed-ecosystem companies, Slack integrates more broadly.
