Verifiable exchange-rate evidence for business records

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

Evidence workflows

Choose the business record you need to support

Start with the job in front of you: an invoice, expense, accounting entry, tax file, audit request, internal review, or dispute record. Each guide explains what to keep, why it matters, and what the next person can verify.

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

When an accounting entry, reconciliation, or close file depends on an exchange rate, keep the evidence beside the calculation. FXProof packages the official source, selected date, rate context, and verification details in a signed proof that an accountant or later reviewer can check.

Open workflow

Audit workpapers

When a workpaper depends on an exchange rate, give the reviewer more than a copied number or link. Keep a signed proof with the source, selected date, rate context, and verification details so the reviewer can inspect the evidence without rebuilding the trail or signing in to your account.

Open workflow

Capital gains

A capital-gains calculation may depend on at least two exchange-rate dates: acquisition and disposal. Keep each official reference input as its own signed proof record, then keep the tax basis, allowable date, and gain calculation in the workpaper or adviser file.

Open workflow

Compliance and internal control

When a control requires the same kind of exchange-rate support across teams or periods, use one repeatable evidence pattern. FXProof keeps the supported official source, selected date, rate context, signed proof, and verification details together while the control owner keeps the policy, approval, and conclusion.

Open workflow

Customs and VAT

When a customs declaration, import file, invoice, or VAT calculation uses an official reference rate, keep the source and selected date with the record. FXProof adds a signed proof and verification path while your team remains responsible for the rule, filing context, and source choice.

Open workflow

Dispute and review support

When a calculation may be questioned later, keep the exchange-rate evidence with the original record before links, pages, or staff memories change. FXProof packages the supported official source, selected date, rate context, signed proof, and verification details; the parties and their advisers decide what the evidence means.

Open workflow

Exchange-rate reconciliation

When an invoice, payment, bank statement, VAT file, or ledger entry shows a different exchange-rate value, first separate the source, selected date, rate direction, and precision. FXProof gives you a signed proof for the official reference input you selected; it does not turn that reference rate into the rate charged by a bank.

Open workflow

Expense review

Keep the receipt or transaction record for what was paid. When an expense policy or reimbursement calculation also uses an official reference rate, attach a signed proof showing the source, selected date, rate context, and verification details so the conversion can be explained later.

Open workflow

Foreign income

Foreign wages, dividends, other income, and foreign tax payments can use different dates and records. FXProof helps you keep signed proof for the official reference input selected for each item, while the reporting rule, date choice, and tax treatment stay with you or your adviser.

Open workflow

Small business

If you run a one-person business, freelance practice, or small company, you may need exchange-rate evidence only a few times a year. FXProof gives you a clear signed proof to keep with an invoice, expense, payment, or tax file without building a finance process of your own.

Open workflow

Tax reporting

When a tax workpaper or schedule uses an official reference rate, keep the source, selected date, rate context, and signed proof with that record. FXProof makes the chosen evidence easier to share and check later; it does not choose the tax treatment or guarantee acceptance.

Open workflow

Year-end close

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.

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.

  • Small business: keep proof with an occasional invoice, expense, payment, or year-end file without building a finance process.
  • 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.
  • Rate reconciliation: separate invoice, payment, bank, VAT, rounding, direction, and source questions before attaching proof.
  • Year-end close: keep separate proof records for historical dates and closing observations.
  • Capital gains: keep acquisition-date and disposal-date exchange-rate evidence as separate records.
  • Foreign income: document the rates used for wages, dividends, other income, and foreign tax payments.
  • Internal review and disputes: preserve a dated, checkable record without claiming to decide the policy or outcome.

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.

Small business

Keep clear evidence with an invoice, expense, payment, or year-end accountant file even if you need it only occasionally.

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.
