What Reviewers Say

Which Should You Choose?

Choose Microsoft Teams if:

  • •Your organization already pays for Microsoft 365 — Teams is included at no extra cost
  • •You need deep integration with SharePoint, OneDrive, Word, and Excel for document collaboration
  • •Video conferencing is a primary use case and you want built-in webinars and town halls
  • •Enterprise compliance features like eDiscovery, legal hold, and DLP are requirements

Choose Slack if:

  • •You prioritize a rich third-party integration ecosystem with 2,600+ apps in the Slack Marketplace
  • •Your team relies on asynchronous communication with threaded conversations and organized channels
  • •You need a standalone chat tool without committing to a full productivity suite
  • •Developer workflows matter — Slack excels at CI/CD notifications, bot integrations, and automation via Workflow Builder

The Slack vs Microsoft Teams decision ultimately hinges on your existing software stack. If your organization already uses Microsoft 365, Teams is the clear financial winner — it is bundled into Business Basic at $6/user/month, making the marginal cost of team chat effectively zero. Slack Pro, by contrast, starts at $8.25/user/month as a standalone product, which adds up quickly at scale: a 100-person team pays $825/month for Slack versus $0 incremental for Teams. That said, Slack remains the superior pure-messaging experience. Its threading model is more intuitive, its integration marketplace is unmatched, and developer teams consistently prefer it for workflow automation. Slack Connect also makes cross-company collaboration seamless, a feature Teams has been slower to match. For cost-conscious organizations already invested in Microsoft 365, Teams is the rational default. For teams that live in Slack and value its ecosystem — particularly engineering and product teams — the premium is worth paying. If you are starting fresh with no existing commitments, try both free tiers: Slack Free gives 90 days of message history, while Teams Free includes 60-minute group meetings. The free plans will quickly reveal which UX your team gravitates toward before you commit budget.
