For an international invoice, state one invoice currency, one amount due, one payment route and who bears conversion or transfer charges. Then record both the invoice-date value and the payment-date value in your home currency.
Most cross-border disputes are not about the work. They are about a client sending the right number in the wrong currency, a bank deducting fees, or the exchange rate moving between invoice and payment.
Decide the currency before the work starts
The contract or accepted estimate should name the billing currency. Choose among:
- Your home currency. The client bears conversion risk and knows the foreign amount only when paying.
- The client’s currency. The client gets certainty and you bear the movement until settlement.
- A negotiated third currency. Useful where both parties price internationally, but it adds a second conversion for someone.
Do not show several grand totals and ask the client to choose. One invoice needs one authoritative amount due. Alternative payment estimates can be shown separately and dated as estimates.
What to put on the invoice
| Field | Why it matters |
|---|---|
| Currency code | USD, EUR and AUD are clearer than a symbol used by several currencies |
| Payment account and route | Prevents the client choosing an expensive or incompatible method |
| Fee rule | States whether sender, recipient or both bear bank charges |
| Due date and time zone | Avoids ambiguity across borders |
| Tax identifiers and supply details | Supports the rule that applies to the transaction |
| Purchase reference | Lets the client’s accounts payable team match it |
Tax treatment varies by seller, buyer, place of supply, registration and product. Do not copy another country’s VAT, GST or sales-tax wording into your invoice. Confirm the rule that applies to the transaction.
The exchange-rate workflow
Assume your books are in GBP and you issue a USD 5,000 invoice. At the invoice date, your documented rate makes it GBP 3,900. When the client pays, the amount received converts to GBP 3,960 after processor fees.
- Record revenue and receivable at GBP 3,900 using the invoice-date policy.
- Record the gross settlement value at the payment-date rate.
- Record processor or bank fees separately, not as lower revenue.
- Record the remaining movement as realized foreign-exchange gain or loss.
If the gross converted value is 3,990 and fees are 30, cash is 3,960. The receivable clears at 3,900, the fee is 30, and the realized exchange gain is 90.
Who should pay transfer fees
Write the rule before invoicing. “All bank charges are for the sender” is clear, but it may not control an intermediary bank that deducts a fee in transit. If receiving the exact amount is essential, use a payment route with visible fees or price a small transfer allowance into the commercial terms.
When the received amount is short, do not automatically mark the invoice paid. Decide whether the shortage is an agreed fee, a customer balance still due, or a discount that needs approval.
Reduce cross-border payment friction
- Offer one local-feeling route where volume justifies it.
- Use an invoice payment link when the supported gateway can settle the invoice currency.
- Test new bank instructions with the client before a large first invoice.
- Show the currency code beside every total and on the payment instructions.
- Reconcile gross amount, fee, refund and net deposit separately.
Using Invoice Crowd
Multi-currency invoicing keeps the customer invoice in its transaction currency while the business books retain a base-currency view. The rate and rounding decision remain visible, which is important when payment arrives later at a different value.
The software can calculate and retain the rate used. Your accounting policy still decides which source and date are appropriate, and your tax adviser should confirm local reporting where cross-border rules apply.
Frequently asked questions
Which currency should I invoice an international client in?
Use the currency agreed in the contract or accepted estimate. Your home currency shifts conversion risk to the client, while the client currency gives them certainty and leaves you with exchange-rate movement until payment.
Can an invoice show totals in two currencies?
It can show a dated informational conversion, but one currency and one amount should be authoritative for payment. Multiple payable totals create ambiguity about what settles the invoice.
Who pays international transfer fees?
The contract should say. Sender-pays is common when the seller must receive the full invoiced amount, but intermediary banks can still deduct charges, so the payment route and short-payment policy also matter.
What happens if the exchange rate changes before payment?
The receivable was recorded at the invoice-date value under your policy. The difference at settlement becomes a realized foreign-exchange gain or loss, with processor and bank fees recorded separately.
Should I record payment fees as lower revenue?
Usually no. Record gross revenue and the payment or bank fee separately. Netting the fee against revenue hides the real sales amount and makes gateway reconciliation harder.
Does multi-currency software decide the correct tax rate?
No. Currency conversion and tax determination are different decisions. Tax depends on the parties, place of supply, registrations and product or service, so confirm the applicable local rule.
