Invoicing Procedure CIZ

How does it work?

1. The professional enters the hours worked periodically (preferably daily) in the CIZ time registration system in Insite.
2. Hours for the relevant month must be submitted no later than the last day of the month. The professional ensures that this is done on time.
3. The hours must be approved by the approver/manager no later than the 3rd working day of the following month.
4. No later than the 5th working day of the following month, HeadFirst receives the approved hours for the previous month from the client.
5. Within 24 hours after receiving the hours, HeadFirst will send you an invoice. This invoice complies with the legal requirements as established by the Dutch Tax and Customs Administration.
6. Hours that are entered and/or approved too late will automatically be carried over to the following month/the next invoicing round.

• The agreed payment term starts from the moment you have received a reversed bill from us.
• If you do not agree with the invoice, you can discuss this with the hiring manager.
