3. Input the VAT number in the VAT Registration No. field.
4. Hit Save.

After that, include the VAT Registration No. field in your invoice.

Here's how:

1. Go to Settings and then select Custom Form styles.
2. Click the Edit button or tap New style.
3. Choose the Content tab and click the upper part of the template.
4. Place a checkmark in the VAT Registration No. box.
5. Hit Done.
