Read how to submit your invoice and how to ensure that payment is not delayed.

Invoices should be sent by e-mail in a .pdf format to facturen@assc.leidenuniv.nl. This email address is meant only for the receipt and processing of invoices. For processing purposes, please send only one invoice per email. 

To prevent payment of an invoice being delayed due to lack of necessary information, it is important that you state the following data on the invoice:

• Billing address of the university:
  Leiden University
  Attn. ASSC Financial
  Rapenburg 70
  2311 EZ Leiden
  The Netherlands
• The 11-digit project number, cost center number or buying order (please ask the original purchaser).
• Name of the person responsible for placing the order
• The VAT number of the university: NL 00.19.35.549 B01
• Your invoice must comply with legal invoice requirements at all times. See requirements set by the Dutch tax authorities

To obtain cost center and project numbers, please contact your university contact person. If any information is missing or the invoice does not meet the mandatory requirements, the university will not accept it and will forward it to the supplier.
