Short answer: easily and in no time! Long answer: Create a new invoice and click Unit price on the invoice row. This opens a view where you can select whether to show the VAT on the invoice. In the case of the VAT reverse charge, the VAT rate or the VAT share must not appear on the invoice, which means you should choose "No VAT".
In addition to this, in the case of the VAT reverse charge, the invoice must inform the buyer that they are required to report and pay the value added tax. There is a separate field for this in the service that opens when you select "No VAT". You can add the description of the VAT reverse charge in this field by clicking the "VAT 0% phrase" field.
After completing these steps, you are ready to send an invoice that is subject to the VAT reverse charge!

Finnish Tax Administration's instructions for applying the VAT reverse charge
When does the VAT reverse charge apply?
The VAT reverse charge applies when all of the following conditions are met:
- The seller is a company that sells construction services or leases out employees to provide construction services,
- The buyer is a company that sells or leases construction services on a non-casual basis, and
- The service is sold in Finland.
Please note that the VAT reverse charge does not apply if the construction service is sold to a private person or if the object of the sales is goods.
The vendor of the construction service must submit an invoice to the buyer. The seller must find out if the buyer meets the conditions for applying the VAT reverse charge. If the conditions are met, the vendor sends a no-tax invoice to the buyer.
The invoice must include all the standard invoice markings, apart from the tax rate and tax amount. The buyer's VAT number must appear on the invoice. In Finnish transactions, this is the same as the buyer's business ID. In addition, the invoice must state that the buyer is obligated to report and pay the value added tax (VAT reverse charge). The basis for the buyer's tax liability is marked on the invoice, for example, by making a reference to Section 8 c of the Value Added Tax Act.
