ESEF (European Single Electronic Format) is an EU requirement stipulating that listed companies must publish their annual reports in XHTML format with embedded iXBRL tagging.
This makes financial information machine-readable, comparable, and easier to analyze.
But ESEF is more than just a technical format. It requires a structured report, consistent use of taxonomies, and rigorous quality assurance. This is where experience makes a difference.
With the Rehngruppen ESEF tool, you can continue working directly in Excel and Word while the report is tagged for ESEF and iXBRL. Financial tables can be tagged in Excel, and footnotes and text in Word, within a workflow that feels natural within your existing reporting process. The goal is to make the ESEF process easy to manage without unnecessary manual steps or complicated external systems.
