The Challenge of XBRL Compliance

Regulatory XBRL filings are complex. A single validation error can delay your filing, trigger regulator queries, or require costly resubmissions.

  • Multiple taxonomy versions with different validation rules
  • Complex technical rules (DTR, XBRL 2.1, Dimensions)
  • Business rules specific to each regulator (ESMA, EIOPA, EBA)
  • Report package requirements with strict structure
