Answer four questions and see whether the document supports the expense and the VAT deduction. The answer uses exactly the same rules Kvits applies to every receipt inside the app.

From €{full} there is no receipt route.
Supplier name, registration number and VAT number; an invoice number; the date; the buyer's name and registration number; the amount excluding VAT, the VAT rate and the VAT amount.
