You will as a Helper receive an invoice after a booking has ended. Since you work as a freelancer with Happy Helper, you will receive notice regarding any transactions on your bookings.
If the invoice shows that a Booker has used a voucher then this amount won't be charged on their account.
Happy Helper will cover the amount the Booker has saved so this will never affect your payout.
You can use this invoice to report your earnings to SKAT.
All invoices can be found and downloaded on your profile under the tab "bookings" if you click "see inventory" and choose a specific month.
OBS! When signing your freelancer contract, you then gave Happy Helper permission to write your CPR number on all invoices. This is to make it easier for Bookers to report the bookings to SKAT to get their tax deduction. This way they don't have to ask you for your CPR number.
