Verifiable exchange-rate evidence for business records

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

Exchange-rate evidence

Keep ECB exchange-rate proof with the invoice-date record

If an invoice calculation uses an ECB reference rate, keep the invoice, the rule or policy behind the date, and the matching proof together. FXProof records the supported ECB dataset, selected date, rate context, document id, payload hash, signature, and verification details in one signed PDF.

Signed FXProof Proof PDF from European Central Bank. This is a static example; readiness for a generated proof depends on the concrete dataset and date.

PDF signature: open the downloaded file in Adobe Acrobat Reader or Acrobat. Browser PDF viewers may hide the signature panel.

Start with the invoice and the rule for its date

Keep the invoice, calculation, and the policy, contract, or professional instruction that explains which date and rate belong in the record. FXProof does not choose that rule for you.

Match the record to supported ECB data

The ECB publishes euro reference rates for working days, with currencies quoted against the euro. Select the supported ECB dataset and date that match your established invoice method, then confirm that the proof bundle is ready.

Keep the signed proof beside the calculation

Attach the Signed FXProof Proof PDF to the invoice file. It keeps the ECB attribution, selected date, rate context, digital signature, document id, payload hash, and verification details together.

A manual file with an ECB link, saved page, and explanatory note can also provide evidence. FXProof makes the handoff repeatable and gives the recipient one public verification path.

Know what the proof does not decide

The ECB remains the source of the rate data. FXProof is not affiliated with or endorsed by the ECB, and the proof does not decide accounting, tax, contract, or recipient acceptance questions.

Questions

Does FXProof choose the invoice exchange-rate date?

No. Use the date required by your policy, contract, professional instruction, or recipient. FXProof documents the supported ECB data and date you selected.

Is the signed PDF issued by the ECB?

No. The ECB publishes the underlying reference-rate data. FXProof independently issues and signs its own source-attributed proof PDF.

What should stay in the invoice file?

Keep the invoice and calculation, the reason for the date and rate choice, and the Signed FXProof Proof PDF used to support that calculation.

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.
