The problem
Your data should work for you.
Resource and operational data sits scattered, arrives in different formats, and takes more effort to gather than it's worth.
"Klappir was foundational for me preparing our first DMA. The process was streamlined, and their tools gave me the structure I needed to work confidently through it."
Rasmus Jørgensen, Head of ESG, M. Goldschmidt Ejendomme
What Changes
Stop rebuilding. Start building on.
Operational resource data from different sources is standardised into one consistent, comparable foundation. That foundation turns raw activity into trusted outputs: reporting, compliance, operational savings, and audit trails.
Operational visibility
Savings become visible before the year-end report
- Resource data structured at the activity level: by entity, asset, supplier, and time period
- Teams see what's costing money now, not what cost money last year
- Patterns that used to surface at year-end now surface as they happen
Report continuity
Your next report starts where the last one left off
- All formats standardised: invoices, meters, spreadsheets, supplier reports, API feeds
- One consistent, comparable structure across your entire organisation
- The foundation carries forward. Next cycle starts where the last one ended
Full traceability
Every number traces back to its source
- Every metric links to its source, methodology, and change history
- Transparent chain from operational activity to disclosure
- Every framework you report against, generated from the same auditable dataset.
