If you want to win public sector contract bids, you need to submit a tender. You do this online, through TenderNed, the Dutch government’s online tendering system. The date and time when the tender closes is specified in the tender documents. Then, the commissioning authority selects the best tender and awards the contract to the winner. All tenderers will receive the result by letter.
To submit a tender properly, you must follow the instructions from the tender documents closely. Tenders submitted late or incorrectly will not be processed by the tendering public-sector organisation. Examples of errors are incorrect addresses, open envelopes, the wrong number of copies, or forgetting to add a legally valid signature.
European Single Procurement Document (ESPD)
Since 1 July 2016 the European Single Procurement Document (in Dutch: UEA) has replaced the Dutch Self-Declaration document. With this document you indicate that you comply with the tender requirements. To draw up the document you can use either the European Union's online ESPD tool or the UEA form (pdf, in Dutch) issued by the Dutch Ministry of Economic Affairs and Climate Policy.
Contracting authorities may only ask for the original documents once you have been awarded the contract. They may, however, request references. The non-bankruptcy certificate is no longer required.
Declaration of conduct
If you have won a contract, the commissioning authority can ask you for a Declaration of conduct for tenderers (Gedragsverklaring aanbesteden, GVA). You can obtain a GVA (in Dutch) from judiciary service Justis (Ministry of Justice and Security).
Lodging an objection against the result
If you disagree with the outcome of the procedure, you have 20 calendar days to lodge an objection against the intention to award. The tender documents specify the relevant rules.
