Keep multi-currency client invoices organized in one place

When your agency bills a London client in GBP, a Berlin client in EUR, and a US client in USD, the invoice list becomes hard to reconcile because every line is in a different currency. A clean way to record the billed currency, the billed amount, and a manually entered home-currency figure keeps each international client's invoices findable and your year-end totals sane. Cash Workspace gives you one place to record each invoice and attach the PDF, organized in a per-client folder.

The problem

Why multi-currency invoices get tangled

Billing across currencies means a single invoice list mixes GBP, EUR, and USD lines that can't be added together. Without recording the currency and a home-currency figure beside each one, totals and follow-up get confusing.

  • A GBP invoice and a USD invoice sit in the same list with no marker for which currency each is in.
  • You remember a client owes '2,400' but can't recall whether that's euros, pounds, or dollars.
  • The rate you used to convert one invoice is lost, so the home-currency figure can't be reconstructed later.
  • International invoices for one client are scattered, so you can't see their full billing history at a glance.
  • At year-end you can't hand the accountant a clean per-client total because everything is in mixed currencies.

The workflow

Record each international invoice consistently

Note the billed currency, the billed amount, and a manually entered home-currency figure on every invoice, then file it under the client.

  1. 1

    Make a folder per client

    Create a folder for each international client, e.g. 'Helix GmbH (EUR)', so all their invoices live together.

  2. 2

    Record the billed amount and currency

    Enter the amount in the currency you actually billed (e.g. 1,800.00 GBP) and note the currency clearly in the record.

  3. 3

    Enter the home-currency figure by hand

    Look up the rate you choose to use, calculate the converted amount yourself, and type it into a separate field with the rate and date noted.

  4. 4

    Attach the invoice

    Attach the PDF you sent so the billed currency and the document never drift apart.

  5. 5

    Set the status

    Mark it sent, partially paid, paid, or overdue, and update it as payment arrives.

  6. 6

    Review per client monthly

    Open each client folder once a month to confirm currencies, statuses, and converted figures look right.

Record structure

What to record for each multi-currency invoice

A consistent set of fields keeps the billed currency and your home-currency view side by side.

Invoice number
Your structured invoice number so the sequence stays auditable.
Client
The international client, kept as a consistent record with their default currency noted.
Billed currency
The currency you invoiced in, e.g. EUR, GBP, USD, CAD.
Billed amount
The invoice total in the billed currency exactly as it appears on the PDF.
Home-currency amount
The converted figure you entered by hand for your own records.
Rate and rate date
The conversion rate you used and the date you used it, noted so the figure can be reconstructed.
Issue and due dates
When you issued it and when payment is due, so overdue international invoices stand out.
Status
Sent, partially paid, paid, or overdue.
Invoice PDF
The sent invoice attached to the record.

Common mistakes

Mistakes to avoid

  • Leaving the currency off a record so a number can't be trusted later.
  • Converting in your head without noting the rate, so the home-currency figure can't be checked.
  • Mixing every client's invoices in one list instead of a folder per client.
  • Treating the manual home-currency figure as if it updates with live rates — it doesn't, it's a fixed note.
  • Forgetting to attach the PDF, so the billed amount and the document live apart.

FAQ

Multi-currency invoice records FAQ

Does Cash Workspace convert currencies automatically?
No. You enter the home-currency figure by hand using a rate you choose, and note the rate and date. Cash Workspace records the billed currency, billed amount, and your converted figure side by side — it does not pull live exchange rates.
How should I note which rate I used?
Record the rate and the date you applied it in a dedicated field or a rate note in the client folder, so the home-currency figure can always be explained.
Can I keep one folder per international client?
Yes. Create a folder per client with their default currency in the name, and file every invoice, status, and converted figure there.
