Case Study: Slack achieves streamlined SEC reporting and a single source of truth with Workiva

Slack Simplifies with Workiva, from S-1 to 10-Q and 10-K

Slack, the enterprise messaging platform, needed a modern, collaborative solution to produce SEC filings after using Workiva to go public. The accounting team wanted a platform that matched Slack’s pace of innovation, kept financial data consistent across documents, simplified XBRL tagging and external reviews, and required minimal training for new staff.

Slack adopted Workiva as a single source of truth: its user‑friendly interface and Workiva Professional Services handled XBRL tagging, while dynamic links, permission controls, and shared workbooks kept numbers consistent across reports and presentations. The result was accurate XBRL filings that exceeded expectations, faster onboarding, easier auditor and counsel reviews, and a streamlined SEC reporting process.
