If you want to win public sector contract bids, you probably have to submit a tender. To do so 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 an incorrect address, open envelope, insufficient copies, or no legally valid signature.
The date and time when the tender closes will be specified in the tender documents. Next, the commissioning authority selects the best tender and awards the contract to the winner. All tenderers will receive the result by letter.
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. For drawing up the document you can use either the European Union's online ESPD tool or the (Dutch-language) UEA form (PDF) issued by the Dutch Ministry of Economic Affairs and Climate Policy.
Contracting authorities may only ask for the original evidential documents once you have been awarded the contract. References, however, may be requested. 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 (Dutch) from judiciary service Justis (Ministry of Justice and Security).
Lodging an objection against the result
If you disagree with the result, you have 20 calendar days to lodge an objection against the intention to award. The tender documents will specify the relevant rules.
