Multi-currency invoicing means sending an invoice in the currency your client actually uses, with amounts formatted the way they expect and tax labeled the way their country calls it. With PayToMe, you pick a client in Tokyo or Kuwait City, set the invoice currency (or a default currency on the client), and the amounts are formatted for that currency without you doing the math. Switching the invoice wording to the client’s language is in development. This page explains how it works, why some currencies have zero or three decimals, and what to watch for when exchange rates are involved.
How multi-currency invoicing works
Sending an invoice abroad usually means guessing: which currency, what format, what to call the tax. PayToMe is designed to remove the guessing.
- Set the client’s currency once. Choose it on the client record. Every new invoice for that client starts in that currency.
- PayToMe formats the amounts correctly. Decimals, thousands separators and the currency symbol follow the currency and the client’s language.
- Tax is labeled for the client’s country. The label can read sales tax, VAT, GST or whatever applies, and you set the rate. You stay in control of the rate.
- You send it. The client sees the invoice in their own language and currency, and pays through a link.
Here is how an invoice in euros will look:

Zero-, two- and three-decimal currencies
Most currencies you meet have two decimals: 100 cents in a dollar or a euro. Not all do, and this is one of the most common causes of wrong invoices.
| Currency | Code | Decimals | Example |
|---|---|---|---|
| US dollar | USD | 2 | 1,250.00 |
| Euro | EUR | 2 | 1,250.00 |
| Japanese yen | JPY | 0 | 1,250 |
| Kuwaiti dinar | KWD | 3 | 1.250 |
The number of decimals comes from the ISO 4217 currency standard, which lists a minor unit for each currency. Payment providers publish their own tables, and a few differ from the standard, so check your provider’s documentation if you take payments in unusual currencies.
Why this breaks invoices
Imagine software that stores every amount as a count of hundredths. For a US dollar invoice, 125000 means 1,250.00. Now apply the same rule to yen: 125000 would be read as 1,250 yen, which is wrong by a factor of 100. The yen has no hundredths, so 125000 should mean 125,000 yen.
The same problem runs the other way for dinars. A KWD amount of 12.500 has three decimals. Round it to two and you have changed the price: 12.50 is correct here, but 12.755 would become 12.76, a difference of 5 fils that adds up across many lines.
PayToMe’s invoice engine does arithmetic in integer minor units and applies each currency’s decimal count, so rounding is exact and repeatable. The AI assistant, Via, never calculates totals.
Local tax labels
Tax goes by different names around the world. Using the wrong one confuses clients and their accountants.
- United States: sales tax, set by state and sometimes city or county.
- European Union and United Kingdom: VAT, value-added tax.
- Australia, Canada, India and others: GST, goods and services tax, with variations in how each country applies it.
PayToMe lets you choose the tax rate for each invoice. It does not decide what tax applies to your sale. That depends on where you and your client are, what you sell and whether either of you is registered, so check with a tax adviser or your tax authority. For the European details, read the guide on VAT invoice requirements and the glossary entry on VAT.
Exchange-rate caveats
Currency rates change every day. That creates three questions you should answer before you invoice abroad.
- Who carries the risk? If you invoice in euros and the euro weakens before you are paid, you receive less in your home currency. If the client pays in your currency, they carry the risk instead.
- Which rate and which date? If an invoice shows both currencies, say which rate you used and when. A rate from invoice day is not the rate on payment day.
- What will the payment method cost? Card networks, banks and payment providers may add a conversion margin or a fee for foreign currency payments. Amounts vary by provider, so check the one you use.
Why it matters
A client who sees an invoice in their own currency does not need a calculator or a rate lookup before approving it. That removes one reason for delay.
- A freelance translator in Lisbon bills a client in Osaka in yen. The client sees whole yen, no decimals, and pays without asking for a recalculation.
- A consultant in Toronto bills a Kuwaiti firm in dinars. The three-decimal amounts match the client’s own bookkeeping.
- A small studio in Austin bills a French agency in euros, with VAT labeled as the client’s accountant expects.
Details that matter
Language
Matching invoice wording, such as “Amount due” and “Payment terms,” to the client’s language, while your own descriptions stay as you write them, is in development.
Reporting in your home currency
Totals in your home currency, using a rate you can inspect, are in development. For incoming-cash planning across currencies, see how the cash flow forecast will present converted totals.
Paying the invoice
Clients pay through online payments in the invoice’s currency where the payment method supports it.
