Common Questions

Does this meet the £5m+ contract requirement?
Yes — all reports are PPN 06/21–compliant, including mandatory Scope 3 categories, Net Zero commitment statements, and methodology declarations.
What file format do you accept?
CSV files with:
  • date (YYYY-MM-DD)
  • description (transaction description)
  • amount_gbp (GBP)

Optional: supplier, category (improves accuracy). Most accounting software can export in this format.

What accounting data do I need?

How do I correct my data?
  1. Review transactions flagged as "Requires_User_Input" in the preview (e.g. add "Gas" or "Electricity" where we've asked)
  2. Correct your original CSV (or use the file we attached in the email)
  3. Re-upload via the link in the email (or from the Upload page) to receive an updated report

Repeat as needed.
FreeAgent users: use the correction link in the email and upload your edited file from the Upload page.

Can I edit the report before downloading?
Yes. Use the preview email to check the figures, correct any flagged transactions, and re-upload before unlocking the full report.
How long does processing take?
Typically just a few minutes. You'll receive an email with your preview or report once complete.
Is this suitable for NHS tenders?
Yes. SustainLedger produces PPN 06/21 compliant Carbon Reduction Plans suitable for UK Government and NHS procurement.
Is my data secure?
Yes — your transactions are processed statelessly and never stored. Full GDPR compliance is maintained.
Can I use this for multiple clients?
Yes — specify a different company name per upload. Multi-client dashboards are coming soon.
