 Invoicing Procedure Reversed Billing ASML

How does the procedure work?

1. The professional enters the hours worked on a weekly basis into the client's time registration system. These hours must be submitted by 10:00 AM on Monday.
2. Every Tuesday by 11:00 AM, the hours worked during the previous week must be approved by the supervisor / hiring manager.
3. Responsibility for obtaining approval lies with the professional (as determined by ASML). The professional must ensure that approval is obtained on time in order to prevent delays in the invoicing and payment process.
4. HeadFirst receives the approved hours on Wednesday and can then create the reversed bill. On Thursday, you will receive the reversed bill with Wednesday's invoice date. This invoice complies with the statutory requirements established by the Dutch Tax and Customs Administration.
5. Hours worked that are approved after 6 weeks will only be sent to us in the next quarterly processing run. A self-billing invoice will be prepared based on that run, and payment will follow according to the agreed payment term.

• The agreed payment term starts on the invoice date of the reversed bill.
• If you do not agree with the invoice, you can discuss this with the hiring manager.
• The reversed bills prepared by us comply with all statutory requirements. More information about reversed billing can be found here.
