Frequently Asked Questions
Get answers on evidence management, automated document validation, and how to establish Sunhat as your central source of truth of your proof.
Reporting tools are excellent for generating the final report, but Sunhat focuses on the Proof and Collaboration layers before the report. We streamline the chaotic data collection from non-experts (HR, Legal) and, crucially, allow you to reuse that verified data for EcoVadis and customer requests—something pure reporting tools don't do.
Collecting data from 40+ entities via email is a nightmare. Sunhat centralizes this by allowing you to assign specific data points to subsidiaries. You can then validate, weight, and consolidate their answers into a single Group Report without manual copy-pasting.
Yes. We designed Sunhat to guide non-experts. The official EFRAG guidelines and definitions are displayed directly next to the data point they need to answer. It’s like having a consultant sitting next to them, ensuring they provide the right data the first time.
