Learn all about ASML invoicing procedure (en)

For ASML, there are two different invoicing procedures. Invoicing through timesheet and selfbilling.

Invoicing Procedure ASML Netherlands B.V. (timesheet)

How does it work?

1. Per month, the professional periodically (preferably daily) records the hours worked on a timesheet.
2. After the end of the month, the professional ensures that the timesheet is signed on time by the hiring manager (you send one invoice per month for the hours worked during the previous month).
3. Attach the signed timesheet to the invoice as a PDF.
4. Send the invoice and timesheet digitally in PDF format, in 1 email to facturatie@headfirst.nl.

You can submit your invoice and signed timesheet monthly by post or digitally by email. We prefer to receive them by email, which also has the advantage for you that we can process them more quickly.

• Invoicing is only possible per month.
• For every invoice submitted, you will receive an acknowledgment of receipt from us within 24 hours after receipt, unless the invoice is submitted during the weekend/on a public holiday. In that case, you will receive an acknowledgment of receipt on the next working day. If you do not receive this confirmation, please contact us to be sure.
• The agreed payment term starts from the moment you have received the acknowledgment of receipt.
• Invoice us at the hourly rate stated in the assignment agreement. No Premium or Basic costs may be deducted. These costs are invoiced to you by Myler by means of a separate invoice and are settled upon payment.

Invoicing Procedure Reversed Billing 

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.

Additional Information

• 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.
