Frequently Asked Questions
Which tool is better for small businesses?
Both tools serve small businesses, but the best choice depends on your specific needs and budget. Consider the free tier availability, per-user pricing, and which features you'll actually use. We recommend trying both with free trials.
Can I migrate my data between these tools?
Yes, both platforms support data import/export. Most offer CSV upload, API access, and some provide dedicated migration tools or concierge migration services for larger accounts.
Do these tools integrate with each other?
While they're competitors, many business tools integrate with both platforms through third-party connectors like Zapier, Make, or native API connections. Check each vendor's integration marketplace for specifics.
What happens if I outgrow my current plan?
Both tools offer scalable pricing tiers. You can typically upgrade your plan at any time. Downgrading may be restricted to billing cycle changes. Review each vendor's upgrade and downgrade policies.
Is there a money-back guarantee?
Policies vary by vendor. Most offer 30-day satisfaction guarantees or allow cancellation with a prorated refund. Check the specific terms before purchasing an annual plan.
Switching Tools: Migration Best Practices
Moving from one collaboration platform to another? Here's how to make it smooth:
Pre-Migration Checklist
- Export all data from your current tool (CSV, API, or native export)
- Clean and deduplicate your data before importing
- Map fields between old and new systems
- Document your current workflows and automation rules
- Identify integrations that need to be reconnected
Data Migration Steps
- Audit current data — Remove duplicates, fix formatting issues, archive old records
- Test import — Use a sandbox/trial account to test with a small data subset
- Full migration — Import complete dataset, verify record counts match
- Validate — Spot-check 50+ records for accuracy, test all integrations
- Run in parallel — Keep both systems active for 2-4 weeks as a safety net
Post-Migration
- Train your team on the new interface and workflows
- Update any external integrations or API connections
- Monitor for 30 days to catch any data gaps or workflow issues
- Cancel your old subscription only after confirming everything works
Integration Ecosystem Deep Dive
Slack's Integration Advantage
Slack's App Directory boasts over 2,600 integrations, including:
- Developer tools: GitHub, GitLab, Jira, PagerDuty, Datadog
- Sales & CRM: Salesforce, HubSpot, Pipedrive
- Project management: Asana, Monday.com, Trello, ClickUp
- Custom bots: Slack's Bolt framework makes it easy to build custom integrations
Slack also offers Workflow Builder — a no-code automation tool that lets anyone create custom workflows without developer help.
Microsoft Teams' Bundled Value
Teams benefits from deep Microsoft 365 integration:
- Office apps: Word, Excel, PowerPoint, OneNote — all accessible directly within Teams
- SharePoint: Document management and intranet capabilities
- Power Platform: Power Automate, Power Apps, Power BI for custom business solutions
- Azure AD: Enterprise-grade identity management and SSO
For organizations already using Microsoft 365, Teams is essentially included in their subscription — making the cost comparison heavily favor Teams.
Which Tool Wins for Specific Use Cases?
| Use Case | Winner | Why |
|---|---|---|
| Software Development | Slack | Better dev tool integrations, threaded discussions |
| Enterprise (500+ employees) | Teams | Microsoft 365 bundle, compliance tools |
| Startups | Slack | Free tier, modern UX, faster adoption |
| Education | Teams | Free for schools, classroom integration |
| Cross-Company Collaboration | Slack Connect | Purpose-built for external partner channels |
| Video Meetings | Teams | Superior meeting features, breakout rooms |
Making the Switch: Migration Realities
If your organization is considering switching between Slack and Teams, understand the practical implications before committing:
Data Migration Limitations
Neither platform offers a native tool to migrate message history, channels, and files from the competitor. Third-party migration tools like Move to Teams or Slack-to-Teams converters handle basic data transfer, but threaded conversations, emoji reactions, pinned messages, and app integrations do not transfer cleanly. Plan for a two-week overlap period where both platforms run simultaneously, allowing teams to move naturally rather than losing access to historical conversations overnight.
Workflow and Integration Rebuilding
Custom Slack workflows, bots, and integrations must be recreated from scratch in Teams (and vice versa). Audit your current platform's active integrations and categorize them as critical (must have on day one), important (needed within 30 days), and nice-to-have (can wait). This prioritized list prevents migration delays caused by trying to recreate every integration before launch.
