Invoicing International Clients from Thailand: Currency, VAT, and Getting Paid

Billing Clients Outside Thailand

More Thai freelancers and small businesses work with clients abroad every year — a design client in Germany, a software client in the US, a consulting retainer in Singapore. Billing them well means solving two problems your domestic invoices don't have: what currency to bill in, and how VAT applies when the client isn't in Thailand.

Get those two things right and getting paid becomes straightforward. Improvise them invoice by invoice, and you end up with mismatched currencies, VAT lines that don't make sense to your accountant, and a reconciliation headache at year end.

Bill in Your Client's Currency

Lemon Invoice lets you invoice in the currency your client actually pays in — US dollars, euros, or any currency you choose per invoice. Your international client sees an amount in their own currency, not a THB figure they have to convert themselves before they can approve it.

One thing worth being clear about: Lemon Invoice doesn't set or guarantee an exchange rate, and it isn't a payment processor. You choose the currency and the amount for that invoice; how the payment actually gets converted — and what your bank or payment provider charges to convert it — happens outside Lemon Invoice, between you and whoever moves the money. Keep that in mind when pricing a job in a foreign currency: what lands in your THB account depends on your bank's rate and fees on the day, not a rate Lemon Invoice quotes you.

VAT on Cross-Border Invoices

Whether VAT applies — and at what rate — to an invoice for a client outside Thailand depends on the specifics of the service and the client. It's worth confirming with your accountant rather than guessing invoice by invoice.

Either way, Lemon Invoice gives you the same clean, per-line VAT handling you'd use on a domestic invoice: add a VAT rate to each line item, and net, VAT, and gross are calculated automatically. If a line carries no VAT, it's simply a 0% line — same layout, same automatic totals — so the invoice is just as clear to a client abroad as it is to a Thai one.

Domestic and International Invoices, Side by Side

You don't need a separate system for the two. In Lemon Invoice, a domestic invoice to a Thai company and an international invoice to a client abroad live on the same dashboard, each with its own currency and VAT treatment:

• Bill in the currency your client actually pays in, set per invoice
• Add VAT per line item, with net, VAT, and gross calculated automatically, whatever rate applies
• Track every invoice as paid, partially paid, or overdue, regardless of currency
• For customers based in Thailand, Lemon Invoice automatically flags them for withholding tax and calculates the standard 3% on the net amount, shown on the receipt — clients abroad aren't affected, since this only applies to Thai-based customers
• Turn a quotation into an invoice, and an invoice into a receipt, without retyping client or line-item details, whatever currency the document is in

Seeing It All in THB

Billing in multiple currencies doesn't mean losing track of your own numbers. Lemon Invoice's dashboard rolls every invoice — whatever currency it was issued in — back into your business's home currency, typically THB, so a month with clients paying in dollars, euros, and baht still adds up to one clear total. For reports and exports your accountant needs broken out by currency, you can also filter to one currency at a time.

A Simple Example

Say you invoice a client in Germany €1,000 for a project. After confirming the right VAT treatment for that engagement with your accountant, you add it as a 0% line — same invoice layout, just a 0% rate instead of 7%. The same week, you invoice a Thai company 20,000 THB for local consulting, with a 7% VAT line: 1,400 THB VAT, 21,400 THB gross. Both invoices sit on the same dashboard — the euro invoice tracked in euros, the baht invoice tracked in baht and automatically flagged for the Thai client's 3% withholding tax once it's paid — and your overview still shows one clear total in THB.

Who This Helps Most

If you're a freelancer, consultant, or small business in Thailand working with clients abroad — alongside Thai clients, or instead of them — multi-currency invoicing built for exactly this keeps both sides of your business on one clean set of documents, instead of juggling separate tools or templates for domestic and international work.

Start Billing Internationally with Confidence

You don't need to overthink invoicing a new international client. Choose their currency, add your line items with the right VAT treatment, and send. Lemon Invoice keeps it organized from there — so the conversation with your accountant is about your business, not about untangling spreadsheets.
