How it works
Four steps from accounting to an answered questionnaire.
- STEP 01
Connect your accounting
Fortnox, Visma, Procountor, Hogia, Business Central or another ERP. Authorised through a single link — no exporting.
- STEP 02
Wellfish categorises
Wellfish AI categorises every transaction into the right emissions category. You only review the exceptions. 95% of the work is already done.
- STEP 03
GHG-traceable results
Scope 1, 2 and 3 under the GHG Protocol. Every figure traces back to its source transaction.
- STEP 04
Fill in the questionnaire
Export the answers in your customer's format — or share a login so an auditor or reviewer can verify the underlying data.
6 weeks of Excel work → an answer in 6 days.
A sheet-metal and mechanics subcontractor, 38 employees received a sustainability questionnaire from A large Nordic vehicle manufacturer. The contract, worth SEK 12.5M, was on the line. Wellfish connected their accounting, categorised the transactions and delivered GHG-traceable answers within one working week.
“The questionnaire landed on a Monday. By the Friday of the following week we had every record, calculations in line with the GHG Protocol and the answers ready to send back. Doing it by hand, we would most likely have missed the deadline.”

Before you start.
- How quickly are we up and running?
- Live in 14 days for standard integrations (Fortnox, Visma, Procountor, Hogia). We handle the implementation, the data collection and the calculations — you spend 60 minutes in total. No workshops, no consulting fees.
- What do we do if the questionnaire requires detailed Scope 3?
- Scope 3 category 1 (purchased goods and services) is calculated automatically from the transactions. For categories that need company-specific data (travel, transport, waste) you get a template to fill in — Wellfish calculates the rest.
- Are the calculations audit-ready?
- Yes. Every figure traces back to an invoice, an account and a GHG Protocol category. We accommodate your customer's auditor and build the documentation so they can verify it without having to call you.
- What happens after the questionnaire is submitted?
- You already have the system running. When the next customer asks — or when VSME/CSRD reporting becomes relevant — you're already set. Wellfish grows with you.
Six weeks in Excel — or an afternoon to get started.
The first 500 records are free — nothing is charged until you enable billing. No fixed fees. Cancel anytime.
