Verifiable exchange-rate evidence for business records

Keep source attribution, selected date, document id, payload hash, and public verification together.

Evidence workflow

Keep exchange-rate proof with year-end close and revaluation workpapers

Year-end close often uses more than one exchange-rate date: opening balances, transaction history, closing observations, and reviewer support may each need their own evidence. FXProof helps you keep a signed proof for each official reference input your close file selected, without choosing the accounting policy or valuation method.

From the first question to reviewer follow-up

List the rates used in the close file

Start with the schedule or workpaper: transaction dates, opening balances, revaluation lines, closing observations, and any reviewer request. Each line should identify the source and date or period used.

Keep policy and proof separate

The accounting policy, valuation method, and source/date decision belong in the close file. FXProof documents the supported official reference input selected under that process.

Use one proof record for each selected input

A year-end file may need more than one proof: one for a historical transaction date, another for a closing observation, and another for a reviewer-selected comparison. Keep each Signed FXProof Proof PDF beside the line or schedule that used it.

Watch for dates without published observations

If the selected close date falls on a weekend or another day without a publication, keep the rule or adviser note that explains the available observation used. Do not bury that decision inside the proof document.

Prepare the reviewer handoff

A reviewer can inspect the source and rate context, validate the signature, and check the document id and payload hash without account access. The accounting conclusion remains in the workpaper.

Historical proof

Use this when an older source/date/rate decision needs to be checked after the reporting period.

Missing publication date

Keep the rule behind any previous, next, or period-date selection when no observation was published that day.

Questions

Can one proof cover every year-end exchange-rate decision?

Usually no. Keep a separate proof for each official source/date input used by the close file, then keep the policy or workpaper explanation beside it.

Does FXProof choose the closing rate for financial statements?

No. Your policy, adviser, or reviewer chooses the source, date, and method. FXProof documents the selected official reference input.

What should the reviewer receive?

Give the reviewer the close workpaper, the policy or date-selection note, and the Signed FXProof Proof PDFs attached to the lines that used them.

Keep the proof with the file that used the rate

Inspect a static sample first, then use an account when you need a proof bundle for a concrete dataset and date.
