Savings that hold up in the boardroom.

A saving only counts once it's measured against a locked baseline and sealed as evidence a CFO, board or auditor can verify. That's how Arcestra reports it.

A How verification works

From baseline to certificate.

01

Baseline

Locked before any change, so every result has a fixed reference.

02

Measurement

Measures the result against the locked baseline.

03

Sealed evidence

Seals it into a record a CFO or auditor can check.

04

Certificate

A savings certificate a CFO, board or auditor can verify.

B The certificate

One record per verified saving.

Each certificate carries the baseline, the measurement, the approval and the sealed evidence behind the number.

  1. 01The verified amountAnnual savings, measured. Not a projection.
  2. 02Projected against measuredThe estimate and the result, side by side, with the variance.
  3. 03Verified (IPMVP)Measured to the industry standard for savings verification.
  4. 04Baseline hashThe fingerprint of the baseline, locked before any change.
  5. 05Evidence content hashThe fingerprint of the sealed record. Change anything and it no longer matches.

C Verify it yourself

Change one number. Watch the seal break.

Every sealed record has a fingerprint. Edit anything in this sample record, even one digit, and it stops matching. That is how a CFO, board or auditor can trust the number has not been touched.
