ESG reporting software compared: Workiva vs Persefoni and a rule-based list

Start with the work your team must complete

Match the buying task to the products to evaluate

Carbon accounting, supplier collection and disclosure preparation can overlap in a platform, but they require different acceptance evidence. Each row names the products of the rule-based list below whose record documents that task with a source, in the list's order; the order is not a ranking.

These scope distinctions follow the linked product sections below. No published feature list establishes that every reporting framework, supplier questionnaire or partner connection is included in a single subscription.

Workiva vs Persefoni: disclosure coordination or carbon inventory?

Start with the bottleneck. Workiva is a candidate when collecting approved sustainability metrics and coordinating disclosure contributors is the central task. Persefoni is a candidate when building and maintaining a carbon inventory is the starting requirement. Both have reporting scope, so compare the actual outputs and applications in the proposal rather than treating these starting points as exclusive capabilities.

Bring the same reporting sample to both demos

These are acceptance tests, not confirmed features of every plan. Persefoni's calculation product page still labels some logs and calculation detail as coming soon to Pro, and advanced data controls and permissions as coming soon to Advanced. Its free Report Builder is distinct from paid GHG Metrics Reports; confirm the exact output and release status before contracting.

1. Calculation ownership: Follow one activity record into a carbon result and a disclosure. Ask Workiva to name the Workiva Carbon or external calculation scope required; ask Persefoni to identify the Pro or Advanced capabilities and exports used.
2. Review and corrections: Assign a contributor and reviewer, correct an approved value, and inspect the supporting evidence and downstream report changes. Workiva's approval procedure lets any approver in a shared step complete that step, so demonstrate separate successive steps when two distinct approvals are necessary. Confirm the required user licences, workspace permissions and history exports.
3. Full programme cost: Request the same entities, data connections, reporting outputs and support in writing. Separate subscription scope from implementation and confirm whether collaboration or a particular export changes the price.

If the organisation uses separate calculation and disclosure tools, demonstrate the transfer and reconciliation between them. Do not assume a native Workiva to Persefoni connector or that either product removes the reporting team's responsibility for the underlying data.

Greenly vs Novisto: supplier response, inventory or disclosure

Choose by the supplier response, inventory or disclosure you must deliver. Carbon engagement and broader ESG evidence can overlap, but product names do not establish equivalent permissions, methods or reporting outputs. An editorial pair, listed alphabetically; other products appear in the rule-based list above.

Test one supplier response and one correction

1. Invite a supplier and identify the access model, paid seat and information visible to that user.
2. Request period, units, boundary and supporting evidence. Distinguish reported data from an estimate or modelled result.
3. Reject an incomplete response, submit a correction and require the intended reviewers to approve in the configured sequence. Identify the accepted version and who can return or override the record.
4. Follow the result into the intended carbon calculation or ESG disclosure. Record manual handoffs and unavailable exports.
5. Confirm that the demonstrated control is released in the purchased account, including API access and reporting add-ons. Greenly lists custom API and SSO as optional additions, and its supplier help marks survey sending as plan-dependent. Novisto documents API ingestion and bulk imports, but a named endpoint, connector or completed implementation is not established by those pages; require the entitlement and mapping in the proposal.
6. Request equivalent supplier counts, reporting periods, entities, connectors and services in every quote.

These are proposed acceptance exercises, not tests QHSEtech performed or proof that every candidate includes each step. A supplier carbon survey is narrower than a labour, ethics or governance questionnaire; scope the actual questionnaire with each candidate.

Name the reporting basis before selecting templates

The GHG Protocol Corporate Standard addresses corporate emissions inventories. Its guidance distinguishes inventory preparation from verification; a calculated total alone is not an assurance conclusion.

For a value-chain inventory, the Scope 3 Standard accounts for emissions in 15 categories, upstream and downstream of a company's operations. Ask each vendor which categories its product calculates, which method each uses (spend-based, activity-based or supplier-specific) and how an estimate is replaced by supplier data without double counting. A product that covers some categories is not a complete Scope 3 inventory.

GRI Standards concern impacts on the economy, environment and people. IFRS S1 addresses sustainability-related risks and opportunities relevant to users of general purpose financial reports. These are different reporting perspectives, with requirements that should not be reduced to interchangeable template names.

For CSRD, establish entity scope, reporting year, national implementation and the applicable ESRS version before configuring tasks. Use the current CSRD scope review. A customer questionnaire and a direct legal reporting obligation are different starting points.

When operational environmental records are the starting point

Evaluate for environmental records connected to operational EHS. Trace a site environmental finding through review, corrective action and the management report, and name the modules involved. Ask the quote to name the selected environmental applications and any separate reporting tool, then demonstrate the site-to-report workflow.

Compare the actual pricing basis, not an invented seat price

Persefoni Pro provides a free starting scope with a single-user base; paid additions and Advanced remain separate procurement decisions. Novisto advertises unlimited users, data points and outputs without publishing a subscription amount. Neither structure can be compared fairly by assigning an assumed price to each contributor. Persefoni plans, Novisto subscription basis.

For quote-only products, request the same reporting boundary and deliverables. Record the quoted currency, billing period, minimum term, entities, modules, supplier access, data preparation, implementation, interfaces and support separately. If a field is absent from the proposal, mark it unknown rather than treating it as included or free.

A demo request is not evidence of a free platform trial; each profile records its own trial status. Persefoni Pro is a permanent free plan with its own limits.
