Carbon Accounting Software for CFOs and Finance Directors

AASB S2 pulled climate disclosure into the annual sustainability report and made the CFO responsible for signing off numbers that are as material to the market as the P&L. Directors sign that report with their duties of care and diligence under Corporations Act section 180 in play, so the evidence behind each number matters. The internal walk-through preparation that year-one Group 1 assurance demanded is what your finance team is about to inherit in year two under reasonable assurance. Carbonly is designed to close that gap by making the audit trail a first-class object rather than an afterthought.

What changes for cfos and finance directors

  • Every emission record links back to the source document, the factor version applied, and the reviewer who confirmed it - the evidence behind each figure is one click away, not a week
  • The CER submission and the sustainability report run off the same activity data, calculated on AR5 as the NGER Regulations require and as AASB S2025-1 permits for the NGER-covered portion, so nothing is entered twice
  • Reporting period lifecycle mirrors the finance close - open, locked, submitted, archived - with restatement requiring written justification captured as load-bearing evidence
  • Custom dashboards reflect the live ledger so board reporting is not a PowerPoint rebuild every quarter
  • MCP server lets you ask ChatGPT or Claude Desktop "what does the audit committee need to see this quarter" and get an audited answer
  • Per-project pricing predictable and scoped by workspace size, not per-seat SaaS licence economics

What the system does

  • Auditor Workspace with dedicated read-only access for the external assurance team, one-click Evidence Pack export for ASSA 5010 walk-through testing
  • Factor version pinning per NGA edition (2024, 2025) - the answer to "which factor edition applied to FY25" is a single click on any record
  • Baseline snapshots for AASB S2 paragraph 21 comparative disclosures preserved immutably at period submit
  • JV consolidation across operational, financial, and equity-share methods so subsidiaries, associates, and joint ventures each disclose under the right boundary
  • Enterprise SSO, SCIM, MFA with security stepup, seven-year audit trail retention, Australian data residency
  • Executive Summary generator produces the AGM slide and board-pack chart set auto-built from the ledger

Frequently asked

How does this reduce personal director sign-off risk under section 180?

Software cannot remove a director's duties, but it can supply evidence. Four gaps are hard to explain in an assurance walk-through: silent factor version drift, spend-based fallback when activity data was available, alias miscoding at volume, and missing provenance. Carbonly addresses each: factor version pinning per NGA edition, quantity-based extraction with methodology labels per record, alias learning only from reviewer corrections, and source-document provenance on every emission record.

What is the annual all-in cost for an ASX 200 deployment?

Per-project pricing by workspace size (Small, Medium, Large, Enterprise) with a $100/month workspace minimum. Watershed does not publish a public price list. Publicly reported figures suggest A$37K to A$264K per year; confirm with the vendor. For Salesforce Net Zero Cloud, publicly reported figures suggest A$48K to A$210K per year; confirm with the vendor (both as at October 2026). Carbonly pricing scales with your actual workspace size, not per seat.

How does the Auditor Workspace change the reasonable assurance conversation?

The external assurance team logs in with dedicated read-only access, steps through any reporting period, and one-click generates an Evidence Pack - a ZIP that bundles every emission ledger row with its source document, extraction event, reviewer confirmation, factor version, and audit-event chain. It is designed to support ASSA 5010 walk-through testing and to reduce the internal preparation a walk-through otherwise needs.
