You should enter the following information to create your invoice correctly:

• ICO number – Enter your Czech ICO number to automatically fill in your registered business details. The Pexpats invoice tool connects to the Czech business database and fills out your Czech company information automatically.

• Date of issue – This is the date when your invoice is issued.

• Due date – This is the latest date when the invoice should be paid.

• Currency – You can issue invoices in any currency. The Pexpats invoice generator always includes the official exchange rate of the Czech National Bank (cnb.cz) in the invoice description. The tool supports all major currencies and applies the correct exchange rate automatically.

• Language – Choose the preferred language of your invoice. The Pexpats invoice tool supports most major languages, including English, Czech, and other EU languages.

• EU registered business – Toggle this option if you are invoicing a company registered in the EU. There is a reverse charge mechanism in the EU, meaning that if you are invoicing an EU-registered business as a Czech freelancer, you should not charge VAT. If it is your first invoice, register for light VAT within 15 days after issuing it.

• Invoice number or variable symbol – Every invoice must include both an invoice number and a variable symbol. It’s recommended to number invoices incrementally, starting from 0 plus the year of issue. For example, your first invoice in the Czech Republic for 2026 would be 012026.

Because it’s the only official-format, 100 % online invoicing platform in the Czech Republic — legally compliant, multilingual, multi-currency, and completely free. It also supports cross-border and EU-registered companies and creates invoices that meet Czech and EU invoicing requirements.
