The Total Economic Impact™ of Slack as a Work Operating System

Fragmented tools and slow handoffs have a cost. A Forrester TEI study quantifies what enterprises gained running work in Slack.

Is your organization paying the hidden cost of fragmented work? Disconnected tools, slow handoffs, and siloed teams don’t just slow you down — they cost you.

Slack commissioned Forrester Consulting to quantify what happens when enterprises run their work through Slack as a true operating system. The findings are striking.

The study interviewed six enterprise decision-makers across SaaS, FinTech, media, transportation, and technology, then built a composite 25,000-employee, $10B-revenue organization to model the results:

312% ROI over three years
$51M in total benefits
$38.6M net present value
Payback in less than 6 months

The largest driver? $50M in collaboration and efficiency gains, as teams replaced tool-switching, slow email chains, and manual coordination with real-time execution in Slack. Sales teams also closed deals faster, with a 15% win rate uplift contributing to $685K in increased profit.
