Wave 1 already filed their FY2024 CSRD reports last year. Wave 2 is in the middle of it now, staring at a spreadsheet full of ESRS datapoints and wondering why the tool their auditor recommended costs more than their entire sustainability team. Wave 3 got a reprieve to FY2028 thanks to the February 2025 Omnibus, which is either a gift or an invitation to procrastinate depending on how you look at it.
If you're shopping for a CSRD platform in 2026, the landscape has sorted itself out. The first wave of "we also do CSRD" generalists has been weeded out by reality. What's left is a small set of tools that actually handle the four things that matter:
- Double materiality — a workflow that produces an auditable IRO matrix, not a Miro board.
- ESRS datapoint coverage — roughly 1,100 datapoints across the 12 topical standards, ~265 of which are mandatory, with the tagging and metadata to prove you didn't skip any.
- XBRL output — digital tagging is a regulatory requirement, not a feature. A platform that can't produce compliant inline XBRL is not a CSRD platform.
- Audit trail for limited assurance — every disclosure tied to a source document, a timestamp, and a reviewer. Auditors ask for this on day one.
Nice-to-have: multi-framework coverage (CDP, ISSB, EU Taxonomy, SBTi) so you're not typing your Scope 3 total into four different tools. Six vendors cleared the bar for this list. Here they are.
1. Workiva
Best for: large listed companies with an existing finance-grade reporting stack and budget to match.
Workiva has been the default choice for CSRD-regulated multinationals since before CSRD existed, because it was already the default choice for integrated financial reporting. The platform's strength is that sustainability disclosures, financial statements, and internal controls live in the same workspace. For a group CFO who has to sign off on both, that matters more than any individual CSRD feature.
The ESRS module covers all 1,100 datapoints with tagging, supports double materiality workflows through the IRO mapper, and produces compliant inline XBRL for the Commission's digital taxonomy. Audit trail is the product's entire personality — every cell has a reviewer, a timestamp, and a chain of custody that survives a Big Four walkthrough without complaint. If your auditor is PwC or EY, they've probably already built playbooks for Workiva.
The catch is price. Workiva does not publish numbers, but implementations for mid-to-large enterprises start around $50,000 per year and climb fast once you add modules, users, and the inevitable "professional services" line item. Setup takes a quarter, not an afternoon. If you're a €200M company trying to file your first CSRD report without hiring a project manager, this is not the tool. If you're a €2B listed industrial with a dedicated reporting team and an SAP back end that needs to plug into something, it's the obvious answer.
Pricing: ~$50,000/year and up, quote-based.
2. Position Green
Best for: Nordic and EU-headquartered companies that want a CSRD-native platform from a firm that was early to ESRS.
Position Green is Scandinavian, which shows up in the product in two ways: clean information architecture, and a regulatory literacy that goes back to the draft ESRS phase. The company grew out of a sustainability consulting practice, so the platform is built around the actual flow of a CSRD engagement rather than retrofitted from a generic ESG tool.
The double materiality workflow is the strongest in this tier. You get a structured IRO library pre-mapped to ESRS topical standards, stakeholder engagement templates, and a scoring matrix that exports directly into your disclosure narrative. Datapoint coverage is full, XBRL tagging is handled, and the audit module gives assurance providers read-only access with comment threads — a small touch that saves hours during fieldwork. Benchmarking against peers is baked in, because roughly half their customer base is in the same Nordic industrial cluster and the data is already there.
Pricing is mid-to-upper-mid market. Not published, but expect €30,000–€80,000 per year depending on entity count and modules. The platform is strongest if you're in Scandinavia, DACH, or Benelux, where their customer density means integrations and regulatory updates land first. For a company in southern Europe without a local implementation partner, onboarding is slower.
Pricing: contact sales; mid-market enterprise range.
3. Novisto
Best for: mid-market multinationals reporting across multiple frameworks, not just CSRD.
Novisto is the platform that tends to win bake-offs when the buyer's requirements list has "CSRD" at the top but "and also CDP, and also SASB, and maybe ISSB next year" underneath. The Montreal-based vendor built its datapoint library framework-agnostic from the start, which means the same Scope 3 category 1 number flows into CSRD E1, CDP Climate C6, and ISSB S2 without being re-entered. For a sustainability lead whose actual job is keeping five disclosures in sync, that's the value proposition.
CSRD coverage itself is thorough. All 12 ESRS standards, double materiality workflow with IRO scoring, XBRL output, and a data request module that lets you push ESRS datapoint requests to subsidiaries or suppliers with deadlines and reminders. Assurance readiness is handled through granular access controls and immutable audit logs. Novisto's customers include a decent mix of European and North American corporates, which means the product doesn't assume you only care about EU frameworks.
Pricing is quote-based but competitive for the mid-market tier — typically $25,000–$60,000 per year based on reported customer conversations, though the vendor doesn't publish. Implementation is faster than Workiva, slower than the SMB tools. The weakness, if you're looking for one, is that the UI can feel dense for first-time CSRD filers. This is a platform that rewards a sustainability team that already knows what it's doing.
Pricing: contact sales; roughly $25K–$60K/year for mid-market.
4. Coolset
Best for: SMBs and mid-caps that need to produce an ESRS report without a €150K consulting engagement.
Coolset is the most interesting entrant in the affordable tier. The Amsterdam-based platform is explicitly built for companies that have been pulled into CSRD scope without the budget or headcount that the Big Four's pricing models assume. It auto-drafts ESRS disclosures from your uploaded data — energy bills, HR exports, supplier spend — and produces a first-pass report that a human then refines. For a Wave 2 company that was told they needed €100K of consultant time to produce the same output, the math is hard to argue with.
The double materiality workflow is guided — more templated than Position Green's, which is a feature if your team has never done one before and a limitation if you have specific industry nuances. ESRS datapoint coverage is complete for the commonly-material standards (E1, S1, G1) and competent elsewhere. XBRL output is supported. The audit trail is lighter than the enterprise tools but sufficient for limited assurance on a mid-cap filing.
Pricing is public, which is unusual in this space and worth rewarding: starting around €500/month for smaller companies and scaling to low five figures for mid-caps. Onboarding is days, not quarters. If you're a 300-person manufacturer filing CSRD for the first time and you've been quoted €120,000 by a Big Four firm — a number we've argued at length is priced for panic, not work — Coolset is the cheapest credible way to bypass that invoice.
Pricing: from ~€500/month; published tiers.
5. Solidflow
Best for: Dutch and Benelux companies that want a CSRD specialist with deep local regulatory fluency.
Solidflow is the specialist's specialist. The Dutch vendor focuses almost exclusively on CSRD and EU sustainability reporting, which means the product isn't trying to be everything — it's trying to be the best at one thing. For companies under Dutch transposition of CSRD (which has its own quirks around assurance scope and ondernemingsraad consultation), this local fluency matters.
The platform's ESRS implementation is thorough, with particular strength in sector-specific datapoints for financial services and real estate — two industries heavily represented in the Benelux listed market. Double materiality is structured around a clean IRO scoring interface that's been iterated on real first-wave filings. XBRL tagging is handled, and the platform has integrations with the major Dutch accounting suites (Exact, Twinfield) that larger international vendors tend to ignore. Audit trail is strong, with specific workflows for interaction with KPMG, Deloitte, and BDO assurance teams, which are the ones auditing most Dutch mid-caps.
The limitation is reach. Outside the Netherlands and Belgium, the customer base is thinner, integrations are fewer, and regulatory updates for non-Dutch transpositions can lag. Pricing is mid-market, not published, but conversations suggest €20,000–€50,000 per year is typical. For a Benelux-headquartered company, Solidflow punches above its weight. For a Spanish or Italian filer, Position Green or Novisto are probably a better fit.
Pricing: contact sales; Benelux mid-market.
6. Formist
Best for: companies that want an AI agent to draft the ESRS report from their existing documents, across CSRD and 14+ other frameworks.
This is the pitch paragraph, so let me write it with the same honesty as the others. Formist is an AI-powered compliance platform built by WeCarbon. It works like a knowledgeable colleague sitting next to you — you upload your annual report, energy bills, HR data, procurement spreadsheet in any language, and it extracts the ESRS datapoints, drafts the disclosures with source-document citations, flags what's missing, and produces XBRL-tagged output. It handles CSRD alongside CBAM, GHG Protocol, EU Taxonomy, CDP, ISSB, SBTi, and 15+ other frameworks in one subscription, which matters because the same Scope 3 number feeds half of them.
For CSRD specifically: Formist covers all 1,100 ESRS datapoints with tagging, supports the double materiality workflow through an IRO card system that you can review and edit line-by-line, and produces inline XBRL compliant with the Commission's ESEF taxonomy. The audit trail is the strongest part of the product — every value in the output links back to the exact paragraph or cell in the source document it came from, which is the single artifact assurance providers ask for first. First-filing drafts that used to take a consulting team 60 working days can be produced in a long afternoon, then reviewed and refined by your internal team.
The honest limitation: Formist does not replace human judgment on the double materiality scoping decisions. It drafts the IRO matrix so you're editing a proposal instead of a blank page, but which topics are material to your business in your jurisdiction remains a call you and your board have to make. And if your assurance provider insists on a Big Four methodology document on the cover page, Formist doesn't give you that — you'd still pair it with a smaller assurance-readiness engagement. For most mid-caps, that combination lands at a total cost well below a bundled Big Four quote. We've done the math on what a reasonable CSRD budget looks like elsewhere; Formist is the operational half of that argument.
Pricing: subscription, public tiers from around €300/month for smaller filers.
How to choose
Three questions will sort most buyers into the right tool faster than any RFP:
1. Who signs the assurance opinion, and what do they want to see? If it's a Big Four audit practice with a prescribed reporting stack, Workiva is usually path-of-least-resistance and the price is defensible. If it's a mid-tier firm or a national audit practice, any of the other five can produce an assurance-ready output and the choice becomes about price and fit.
2. How many frameworks do you actually report against? CSRD-only: Solidflow or Coolset. CSRD plus CDP plus ISSB plus EU Taxonomy plus CBAM: Novisto or Formist, because the cross-framework data reuse pays for itself in the first year. Position Green and Workiva sit in the middle — strong on CSRD, competent elsewhere.
3. What's your internal capacity? A two-person sustainability team with a finance analyst part-time needs a tool that drafts, not a tool that gives you a very good spreadsheet. Formist and Coolset are the two platforms that explicitly reduce the drafting workload. A ten-person team with a dedicated reporting lead can operate Workiva, Novisto, or Position Green effectively; the sophistication of the tool stops being a burden and starts being an advantage.
Wave 2 filings are due now, FY2025 data, with limited assurance from day one. If you're still choosing a tool in April, you're late but not catastrophically so — any of the platforms above can produce a first draft inside a quarter. What you can't afford to do is spend another six weeks in vendor bake-offs and end up filing on Excel because the procurement process outran the deadline. Pick one that fits your scale, your auditor, and your team's appetite for drafting, and start uploading documents.
Formist is built by WeCarbon, a climate-tech company with offices in Paris, Dubai, and Shanghai. It supports CSRD/ESRS, CBAM, GHG Protocol, EU Taxonomy, CDP, ISSB, SBTi, and 15+ other sustainability frameworks under a single subscription.
