Signed proof documents for official exchange rates

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

Evidence workflows

Exchange-rate proof use cases

Choose the business file you need to support. Each workflow shows which exchange-rate evidence to keep and what a reviewer can check.

Choose the file you need to support

Each workflow starts with a different business question and ends with a proof document a reviewer can inspect.

Accounting close

Attach one signed exchange-rate proof PDF to the accounting entry, financial-report support file, or close file that used the rate.

Open workflow

Audit workpapers

Attach one signed exchange-rate proof PDF to the audit workpaper, then let the reviewer inspect the source and rate context and use the public verification details in that same file.

Open workflow

Customs and VAT

Attach a signed exchange-rate proof PDF to the invoice, declaration, calculation, or VAT file that used the rate.

Open workflow

Expense review

Attach a signed exchange-rate proof PDF to the expense claim or reimbursement record when the conversion may need review later.

Open workflow

Tax reporting

Attach a signed proof PDF to the tax workpaper or schedule that used the rate, with the selected source, date, rate context, and FXProof verification information in one file.

Open workflow

Match the proof to the file in front of you

Start with the file, not the feature list. An accounting close, tax workpaper, audit file, customs declaration, and expense review each raise a different reviewer question.

The workflow pages below show where the proof document belongs, what context the preparer keeps, and what a reviewer can check later.

Common workflows

Each workflow has a different business question, but the proof pattern is the same: attach the Signed FXProof Proof PDF to the business file that used the rate. The proof and verification fields stay inside the PDF.

  • Audit evidence: give auditors a source-attributed proof document instead of scattered screenshots and links.
  • Tax reporting: keep the official source and historical date used for a filing or client workpaper.
  • Accounting close: use one repeatable proof standard for month-end or year-end exchange-rate support.
  • Customs and VAT: support import/export and VAT files with traceable source/date/rate evidence.
  • Expense review: attach a verifiable proof document when a conversion needs later review.

What every workflow gets

FXProof is designed for the evidence handoff. The person preparing the file can keep the signed proof PDF, while the reviewer can use public verification without needing access to the preparer account.

  • Signed proof document for the selected source and date.
  • Source attribution and proof metadata in one place.
  • Document id and payload hash for public verification.
  • Clear limitation wording for recipient, procedure, and jurisdiction.

Why teams switch from manual evidence

Screenshots and copied URLs can support one file, but they become hard to compare across clients, periods, and reviewers.

FXProof gives preparers a repeatable artifact and gives reviewers a public verification path without turning the official rates into proprietary FXProof data.

Audit support

Package source, date, rate, document id, and payload hash so audit evidence is easier to review later.

Open audit use case

Tax reporting

Keep historical source/date/rate evidence with the client file or tax workpaper.

Open tax use case

Accounting close

Use a consistent proof standard for exchange rates during close, review, and internal control work.

Questions

Which teams use FXProof use cases?

FXProof is built for finance, accounting, tax, audit, customs/VAT, expense, compliance, and consultant workflows that need source-attributed exchange-rate evidence.

Is this only for API users?

No. API access is optional. The main workflow is the signed proof document, proof metadata, and public verification.

Does FXProof replace professional judgment?

No. FXProof provides source-attributed proof documents and verification metadata. Acceptance depends on the recipient, procedure, and jurisdiction.

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.
