Keep a consistent exchange-rate evidence trail for internal review

Why inconsistent evidence creates review work

When one file has a screenshot, another has a copied link, and a third has only a number, reviewers have to reconstruct the source and date before they can assess the calculation.

Which source, date, and context should stay together?

Keep the policy or control record, the business calculation, and the proof for the source and date used. FXProof provides the proof artifact; your process records who selected the rate, why it applied, and who approved the result.

• Official source and selected date.
• Rate context tied to the reviewed record.
• Signed proof with document id and payload hash.
• Public verification path for a later reviewer.

How can another person review the proof later?

The reviewer can inspect the source and rate context, validate the digital signature, and use the document id and payload hash shown in the PDF without access to the preparer account.

How does one evidence standard reduce ad hoc explanations?

The same evidence structure across files lets reviewers start from a familiar source, date, rate, and verification trail. The preparer still explains why the rate applies, but does not need to rebuild its provenance each time.

What does the proof establish, and what remains a professional decision?

The proof records the supported official source, selected date, rate context, and FXProof verification details. It does not define policy, approve exceptions, certify compliance, or guarantee acceptance. Keep those decisions and their owners in your own records.

How do you begin with one recurring use case?

Choose one recurring calculation or review where the same official-rate evidence is needed. Keep the business context and approval in the control record, then attach the proof using the same pattern each period.
