Exchange-rate evidence

Keep NBK exchange-rate proof with the accounting entry

When an accounting entry or close file uses a National Bank of Kazakhstan exchange rate, keep the calculation, source date, and signed proof together. FXProof records the supported NBK dataset, rate context, document id, payload hash, signature, and verification details for the next reviewer.

FXProof static proof sample preview

Signed FXProof Proof PDF from National Bank of Kazakhstan. 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.

Keep the accounting basis with the entry

Record the calculation, accounting policy, and reason for the selected source and date in the entry, reconciliation, or close file. FXProof does not decide the accounting treatment.

Match the record to supported NBK data

The National Bank of Kazakhstan publishes official market exchange rates against the tenge. Select the supported NBK dataset and date used by the accounting method, then confirm that the proof bundle is ready.

Attach one checkable proof document

Keep the Signed FXProof Proof PDF beside the entry or schedule. It records the NBK attribution, selected date, rate context, digital signature, document id, payload hash, and public verification information.

A saved NBK page and manual note can support a record. The signed proof gives repeated close work one consistent artifact and a direct check for the next reviewer.

Keep professional conclusions in the accounting file

NBK remains the source of the rate data. FXProof is not affiliated with or endorsed by NBK. Verification does not certify the accounting entry, financial report, or recipient acceptance.

NBK source and date

Review the supported NBK source, selected-date readiness, and non-affiliation note.

Questions

Does FXProof choose the accounting rate or date?

No. Follow the accounting policy or professional instruction for the record. FXProof documents the supported NBK source and date you selected.

Is the signed proof issued by NBK?

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

What should the next reviewer receive?

Keep the accounting entry or schedule, the policy and calculation context, and the Signed FXProof Proof PDF together.

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.
