Frequently asked questions

Is my invoice data saved securely?

Yes, invoices you save are stored in your browser's local storage on your device. They are not sent to our servers, so your data stays private to you.

Does it handle reverse charge for EU cross-border sales?

Yes, for Sweden, Denmark, and Finland, if you select a country and the invoice date, the tool automatically detects when reverse charge applies (e.g., for B2B cross-border transactions) and adjusts the VAT accordingly. Norway is not in the EU, so reverse charge is not applied there.

Can I print the invoice directly?

Yes, after calculating and saving, you can open any saved invoice and use your browser's print function to generate a printable version to send to your client.
