Invoicing abroad

A light entrepreneur can invoice foreign clients through Truster, and invoices can be created in euros, US dollars or Swedish kronor. The biggest difference from domestic invoicing is how VAT is handled: it depends on whether the client is based in an EU country or outside it, and whether the client is a business or a consumer. This guide walks through the rules at a conceptual level; always confirm the exact tax rules at vero.fi (the Finnish Tax Administration's service) or with your client's accountant before sending your first invoice.

Sales to EU countries

When you sell a service to a business client in another EU country, the invoice is often subject to the reverse charge mechanism. In practice, this means the buyer reports the VAT in their own country instead of the seller reporting it in Finland: no Finnish VAT is added to the invoice, but the invoice references the reverse charge instead. To apply this, you need the business client's VAT identification number, so always request it before invoicing.

For consumer clients and different types of services, the rules vary: tax treatment can depend, for example, on where the service is performed and what kind of service it is. Don't apply rules of thumb to these situations — confirm the correct treatment at vero.fi or with a bookkeeping professional. When invoicing through Truster, make sure to indicate clearly that the client is abroad while creating the invoice, so it's generated correctly.

Sales outside the EU

Sales to countries outside the EU are governed by their own rules. As a general concept, selling services to a client outside the EU is often outside the scope of Finnish VAT, but the outcome depends on the nature of the service and where it's deemed to be sold. The destination country may also have its own requirements. So the same advice applies here too: confirm the treatment at vero.fi or with your accountant before invoicing, and don't guess.

The practical side is simpler than the tax questions: agree on payment terms and payment method in writing in advance, and keep in mind that international payments can move between banks more slowly than domestic ones. With a foreign client, a written agreement becomes even more important, since resolving disputes across borders is laborious. A clear contract, a reasonable advance payment for larger jobs, and careful invoicing keep the risks in check.

Choosing a currency: euros, dollars or kronor

Truster supports invoicing in three currencies: euros (EUR), US dollars (USD) and Swedish kronor (SEK). When choosing a currency, think about your client: an invoice in the client's own currency is easier to approve and pay, which usually means faster payment for you. Kronor is the natural currency for a Swedish client and dollars for a US client, while euros are the clearest choice within the eurozone and for many international assignments.

Remember that exchange rates fluctuate: when you price a job in dollars or kronor, its value in euros moves with the exchange rate between when the invoice is sent and when it's paid. For long projects, you can reduce currency risk by invoicing in several instalments as the work progresses. Always agree on the currency in writing in your quote or contract, so it doesn't become a point of dispute at invoicing time.

How to invoice abroad with Truster

A foreign invoice is created in Truster the same way as a domestic one: you enter the client's details, describe the work done, choose the currency and payment terms, and send the invoice. Record the client's details with extra care: official name, address including country, and the VAT identification number for a business client. Truster handles your salary payment and withholding tax to Finland as usual, so your own tax treatment as an employee doesn't change just because the client is abroad.

In summary: invoicing abroad works well as a light entrepreneur, as long as three things are in order. Check the VAT treatment in advance at vero.fi or with an accountant, request the VAT identification number from an EU business client, and agree on the currency and payment terms in writing. Truster supports invoicing in euros, dollars and kronor, so you can take on international assignments without setting up your own company.

Language and practices in international invoicing

With a foreign client, it's also worth agreeing on language and communication practices. Write the quote, contract and invoice in a language the client understands — in practice usually English, though Swedish works naturally with Swedish clients. When the contract and invoice are in the same language, the risk of misunderstandings is smaller, and in any dispute both parties can refer to the same text. If you do expert work remotely, also record time zone differences and response times in the contract: when you're reachable, how quickly you respond to messages, and which channels you use to stay in touch. Clear rules of engagement build trust, especially when the client never meets you face to face.

Payment practices vary by country: different countries have different habits around payment periods and payment methods, and an international bank transfer can take longer than a domestic one. Agree on payment terms in writing and don't assume the Finnish 14-day practice is a given for your client. Also make sure the client pays the invoice in full, with any bank fees covered on the payer's side — this too can be agreed on the invoice and in the contract.

Checklist before your first job abroad

Go through these points before starting work for a foreign client. Check the VAT treatment for your situation at vero.fi or with a bookkeeping professional. Request the VAT identification number from an EU business client and check the client's official details. Agree in writing on the scope of work, price, currency, payment terms and language. Consider an advance payment or instalment invoicing, since collecting debts across borders is laborious. Make sure the client has all the information they need to make the payment from abroad.

An international client can be a significant opportunity for a light entrepreneur: the market is bigger than the domestic one, and there may be more demand — and better pricing — for your skills abroad. Especially in remote expert work such as design, programming, translation and content production, the client's location matters less and less, and Finnish reliability is a valued trait in international markets. Once you've sorted out the tax questions and have a solid contract template, the next jobs abroad will go smoothly as routine. Truster makes the practical side easy: invoice through the app in euros, dollars or kronor, and your salary and related costs are handled to Finland as usual.

Frequently asked questions

Can a light entrepreneur invoice a foreign client?

Yes. Through Truster you can invoice foreign business and private clients, and invoices can be created in euros, US dollars or Swedish kronor. VAT treatment differs from domestic sales, so confirm it in advance at vero.fi (the Finnish Tax Administration's service) or with your accountant.

What is the reverse charge mechanism?

Reverse charge means the buyer reports the VAT in their own country instead of the seller. It's often applied when you sell a service to a business in another EU country: no Finnish VAT is added to the invoice, but the invoice references the reverse charge instead. Check whether it applies to your situation at vero.fi.

In which currencies can I invoice with Truster?

Truster supports invoicing in euros (EUR), US dollars (USD) and Swedish kronor (SEK). An invoice in the client's own currency is usually easier to approve and faster to pay. Agree on the currency in writing before starting the work.

Does my own taxation change when the client is abroad?

The tax treatment of your salary doesn't change: Truster pays your salary and handles withholding tax to Finland as usual. The invoice's VAT treatment, on the other hand, depends on the client's country and the nature of the service, and it's worth confirming at vero.fi or with an accountant.
