B2B service only (not for individual consumers)

Procurement, internal approval, audit, or third-party submission can stall when calculation grounds are requested.

Return verifiable evidence without disclosing internal formulas or implementation.

Return acceptance‑ready deliverables

SCU is a B2B service that takes existing data and calculation conditions, then fixes them into a deliverable the receiving side can verify. Here, fixing means closing the input, conditions, and outcome into a state where later changes can be detected by verification.

That makes it easier to preserve explanation responsibility across procurement, internal approval, audit, and third-party submission,
and helps keep meetings and reviews moving.

Fit

Publication terms are acceptable

On the standard track, publishing the usage record is a condition of use.

Input

Existing data and conditions can be shared

Acceptance

The output should be verifiable evidence

Cases that cannot be published, or cases only meant to close a decision, have separate lanes (anonymous track / completion paths). Which lane fits is confirmed during consultation.

What you receive

See the minimum returned items first

The standard return includes the minimum items needed for later verification. Depending on the case, additional items such as an acceptance result may be added.

Accepted input

Fixed time

Reference number

Verification value

Integrity value

Even when additional items exist, they do not reopen internal formulas or internal procedures.

Acceptance

Check by reference and value

Use the reference number and verification value to check match or mismatch. The detailed procedure is on the verification page.

Standard Track

Standard Track details live on separate pages

The Standard Track is the normal path for cases that can accept publication of usage records. Pricing, categories, and completion paths stay as links here.
