First make sure that your buyer has a registered VAT number and add it to your customer data.
Both the buyer's and the seller's VAT numbers need to be on the invoice. You can easily check the buyer's VAT number on the European Commission's online service. You can add your own VAT number at My account -> Company contact information.
Creating an invoice for sales of services to another EU country:
1. Go to the Invoices tab and click on Create invoice on the right.
2. On the right side of the editor you see the invoicing settings panel. Select Sales of services to other EU member states as invoice type.
3. If needed, you can also choose another Currency and Invoicing language.
Zervant will automatically remove the VAT from the invoice and add the legally required text "Steuerschuldnerschaft des Leistungsempfängers" on the invoice footnote. The sales will also automatically appear correctly on the VAT report.
Attention! If you choose another currency and add products/services on the invoice directly from your registry, you will need to manually recalculate the price of the product/service according to the new currency.
