The list

• Strengths: Keeps supplier requests inside the voluntary standard, at 23 data points or 9 for micro suppliers. Gives each data point an owner, validator, contributor and auditor. Exports the statement tagged in XBRL.

8. Workiva

• Who it is for: Finance and sustainability teams that report both in one controlled place.
• Best for: Finance teams that want the sustainability statement next to the annual report.
• Strengths: Puts the double materiality assessment and ESRS gap analysis in the same tool as financial reporting. Connects to source systems with more than 60 connectors and manages data requests. Keeps real-time audit trails and gives auditors access.

9. Greenomy

• Who it is for: Companies that want software plus advisers for CSRD, the voluntary standard and the EU Taxonomy.
• Best for: Companies that want advisers beside the software for CSRD and the voluntary standard.
• Strengths: Digitises the ESRS, with over 1,200 data points. Covers CSRD, the voluntary standard and the EU Taxonomy in one place. Has advisers for the double materiality assessment.
• Limits: Its page does not mention a tagged report for filing or an audit trail.

What the EU sets

• The CSRD will cover, for financial years starting on or after 1 January 2027, companies with more than 1,000 employees and more than EUR 450 million net turnover. EU countries put the change into national law by 19 March 2027.
• Non-EU groups with an EU subsidiary or branch come in when their net turnover in the EU is above EUR 450 million for each of the last two financial years, and the EU subsidiary or branch itself has net turnover above EUR 200 million.
• Value chain cap (limit on what big buyers can ask): a company with 1,000 employees or fewer can decline requests for more than the voluntary standard the Commission adopted on 3 July 2026 asks. That standard builds on Commission Recommendation (EU) 2025/1710, which comes from the voluntary standard for small and medium-sized enterprises (VSME) from EFRAG.
• On 3 July 2026 the European Commission adopted two sets of rules: the simplified ESRS, and a voluntary standard for companies the cap protects.
• Reports need limited assurance (an auditor checks the report at a basic level). The Commission adopts the standards for it by 1 July 2027.

Side by side

Senseible is not a CSRD reporting tool, so it is not scored here. Its reporting format is the Business Responsibility and Sustainability Report (BRSR), and it helps Indian suppliers turn bills into carbon records an EU buyer can use.

How to choose

1. Runs the double materiality assessment, which decides what you report. Ask: "Can we see how one topic was scored and who approved it?"
2. Holds the ESRS data points (the figures the standard asks for), with gaps shown. Ask: "Which data points are in the tool today, and how many are simplified?"
3. Collects data from sites, teams or suppliers and tracks who has replied. Ask: "How does a plant manager send a figure, and who sees it is late?"
4. Supports the voluntary standard that caps what smaller suppliers must answer. Ask: "Can a supplier with under 1,000 staff answer with the voluntary standard only?"
5. Tags the report in a machine-readable format for digital filing. Ask: "Which format does the tagged file come out in, and who checks it?"
6. Keeps a trail behind each figure and lets the auditor in. Ask: "Click one figure and walk me back to the document and the approver."
7. Already carries the simplified ESRS adopted in 2026. Ask: "What changed in the tool when the simplified ESRS came out?"
