Standard Business Reporting is the standard for digital reporting in the Netherlands. Important ingredients for SBR are the reporting standard XBRL, the Dutch Taxonomy and the SOAP-based specification for secure system-to-system data exchange.

OpenSBR offers an overview of open source projects which comply with SBR standards. OpenSBR contributes to the further adoption of SBR.


OpenSBR refers to open source projects. The projects are publicly available on the internet, although the license conditions are determined by the respective authors.
