Log the exchange rate you used, by hand, per record

When you're paid in several currencies, the figure that matters at review time is the home-currency equivalent you used on a given date — and that's exactly the thing nobody writes down. A manual rate note attached to each foreign invoice or expense means your converted totals can always be reconstructed. Cash Workspace gives you one place to attach a hand-entered rate-and-date note to each foreign-currency record. There are no live rates.

The problem

Why exchange-rate context disappears

The rate you used is a moment-in-time decision, and if it isn't written down beside the record, it's gone. Reconstructing it months later is guesswork.

  • You converted a EUR invoice once but never noted the rate.
  • Months later you can't tell which date's rate applied.
  • A foreign expense has no home-currency figure attached at all.
  • Two records from the same week used slightly different rates and you can't tell which.
  • At year-end, reconstructing converted totals means re-guessing every rate.

The workflow

Attach a rate note to every foreign record

Each time you record a foreign-currency invoice or expense, add a manual note of the rate and date so the conversion is captured at the moment you make it.

  1. 1

    Record the foreign amount

    Enter the amount and currency exactly as invoiced or spent, e.g. 480 EUR.

  2. 2

    Note the rate and date

    Add a manual note: the exchange rate you used and the date you used it, e.g. 'EUR 1 = 1.08 USD on 2026-03-14'.

  3. 3

    Add the converted figure

    Record the home-currency equivalent you calculated, so the figure and its rate sit together.

  4. 4

    Attach the source

    Attach the invoice or receipt so the original amount, your rate note, and the document are linked.

  5. 5

    Reconcile periodically

    Review the log so converted totals stay consistent and reconstructable.

Record structure

What to record in each rate note

A few consistent fields make every conversion reconstructable months later.

Record reference
Which invoice or expense the note belongs to, so it's clear what it converts.
Foreign amount
The original amount and its currency, e.g. 480 EUR.
Exchange rate
The rate you used, entered by hand, e.g. 1 EUR = 1.08 USD.
Rate date
The date that rate applied, so the right moment is captured.
Home-currency figure
The converted equivalent you calculated from the rate.
Rate source note
Where you got the rate, e.g. 'bank statement' or 'a rate site on the day', for your own reference.
Attached document
The invoice or receipt the note belongs to, attached to the record.

Example setup

An example rate-note log

One way to keep rate notes inside your workspace.

2026 EUR rate notes

A note per euro invoice or expense: amount, rate, date, and the home-currency figure.

2026 GBP rate notes

Pound records with their rate, date, and converted figure, attached to each source document.

Rate-source log

A short note of where each rate came from, so the method stays consistent.

Common mistakes

Mistakes to avoid

  • Recording the foreign amount but never the rate you used.
  • Leaving out the date, so it's unclear which rate applied.
  • Using a different rate source each time without noting which.
  • Keeping the converted figure in your head instead of on the record.
  • Detaching the rate note from the invoice or receipt it belongs to.

FAQ

Exchange-rate note log FAQ

Does Cash Workspace pull live exchange rates?
No. There are no live or automatic rates. You enter the rate and date yourself, and Cash Workspace stores your note beside the record so it stays with the original amount.
Which rate should I record?
Record the rate you actually used to convert, along with its date and where you got it. Keeping the source consistent makes your totals easier to reconcile. For which rate to use for tax, confirm with a qualified professional.
Why attach the rate note to each record?
So the foreign amount, the rate, the date, and the converted figure all live together. That way, months later, you can reconstruct any converted total without guessing.
