Submission of a Tender, Indicative Tender, Request to Participate and Others


Individual submission types are described below and are available based on the specific type of a procurement procedure in its various phases and life cycles. Submission can only be made by a person with the assigned role of "Participant of a procurement procedure".

In case that the contracting authority requires the attachment of an electronic signature during submission, it is necessary to install the Crypto native app and Crypto web Extension add-ons (available for download here).

You can verify the correctness of your electronic signature through the compatibility test on the public portal of the NEN system.

It is not necessary to install these add-ons for encrypting electronic submissions.

Submissions can be made from various locations in the NEN system, and the subsequent form will be identical.

1. Main screen - tab "Procurement Procedures"

In the white field on the "All" or "My Procedures" folder, enter the number or name of the public contract. After pressing the enter key, procurement procedures that match the data you entered will be displayed. Using the "three dots" quick option button, you can submit a tender, withdraw a tender, or add or remove a procurement procedure from your procedures.

If you click on the "i" icon next to a procurement procedure, its details will appear. The "Submit a tender/ request to participate/ indicative tender" button is located under the option "Economic operator’s actions" in the top grey toolbar.

2. Tile "Make a Submission"

image-20240314-102518.png

You can search/ add the "Make a Submission" tile using the search bar "What would you like to do?" or the "plus" icon. After clicking on this tile, folders "Only My Procedures" and "All" will appear. You can search for a particular procurement procedure using the filter.

3. Tab "Activities in My Procedures" - invitation to submission

In the "Activities in My Procedures" tab (located on the main screen on the right) - the "Invitations" folder. After opening the detail, you will find the "Submit a tender" button in the top toolbar.

image-20240314-104111.png

The display of the "Tender" form depends on the settings of the contracting authority. However, process of completing and submitting the tender will always be analogically identical.

  1. The tender form will be displayed, where you fill in the price and subsequently attach files.

If the economic operator is not a VAT payer, enter the same amount in the column for the price without VAT and the price with VAT. The NEN system will add a 0% VAT rate.

  1. A form will be displayed where you will only upload files.

If it refers to a procurement procedure within the ZZVZ (or if the contracting authority sets it), encryption will be required. The NEN system will not allow you to submit the tender without it.

The number of uploaded files is not limited, however, the total size of individual files must not exceed 1 GB, and at the same time, the size of each file must not exceed 110 MB. Multiple files can also be uploaded through a ZIP file (or alternatively, 7z, RAR), with the file size not exceeding 110 MB. If you need to insert a file of an unsupported format, you can create a ZIP file from it, which is already supported.

Permissible attachment formats are listed in the NEN System Operating Rules.

Individual submission types

Submission of an unencrypted tender

Submission of an unencrypted tender

  1. In the tender form, in the "Information about the submission" section, the submission name is automatically pre-filled but it can be changed. Changing the tender’s name is not visible to the contracting authority and is solely for your better orientation. Information about encryption is also provided here.

  2. In the "Details of the tender" section, you will fill in the tender price and, in the "Files" section, you will attach the necessary documents.

  1. If the contracting authority reserves the right to "Disclosure of the tender price or life cycle costs" in a way that their separate disclosure will be possible only after the evaluation of quality criteria, there will be two sections for uploading files in the tender form. In the first section, upload only files related to the tender price or life cycle costs. In the second section, upload all other files that do not contain the tender price or life cycle costs.

Therefore, we recommend that economic operators take steps leading to such an action well in advance.

Submission of a tender, request to participate, indicative tender for public contracts divided into lots

Same submission deadline for all lots

If a procurement procedure is divided into lots, the submission is performed the same way as for a procurement procedure that is not divided. First, you will indicate individual lots for which you would like to make a submission, fill in the details, and upload files to your selected lots. The submissions for these lots are sent at the same time in one step, not separately.

image-20240314-120752.png

The process of inserting file attachments and completing the submission is completely identical to a procurement procedure not divided into lots.

Different submission deadline for lots

If a public contract is divided into lots, but the contracting authority has set a separate submission deadline for each lot, you must submit individually to each lot. Therefore, you will select the lot you are interested in, fill in the form, and send the submission. Then, you will select another lot and repeat this process.

In this case, we recommend clicking on the detail of the particular procurement procedure through the "i" icon.

image-20240314-115241.png

Subsequently, through the economic operator’s actions, select if you want to submit a tender/ request to participate/ indicative tender/ preliminary interest. A list of all lots will be displayed.

image-20240314-121830.png

The "Submit a tender/ request to participate/ indicative tender/ preliminary interest" button is also available after clicking on the specific lot in the economic operator’s actions - submit a tender, etc.

Multi-phase procedure for a public contract divided into lots

If you are participating in another phase within a multi-phase procedure - you initially submitted, for example, a request to participate and now, in the next phase, you are submitting a tender - the submission is done through the procedure details. The option "Submit a tender" is no longer available under the "Economic operator’s actions" button. In this case, it is necessary to display the specific lot of the public contract in the "Lots of the public contract" folder using the "i" icon. Here, under the option "Economic operator’s actions" in the top grey toolbar, you need to select "Submit a tender".

image-20240314-122242.png
Submission of a tender for individual items

Submission of a tender for individual items

In the case where the contracting authority has determined, during specification the procurement procedure, that the subject-matter items of the public contract will also serve as items of the tender, you will fill in prices for individual items when submitting the tender. You can fill in the prices directly in the "All" folder or in individual folders if specified by the contracting authority.

image-20240314-142823.png

After filling in the prices for all items in the tender, the NEN system will automatically calculate the total tender price. You can insert the prices by downloading all items into MS Excel, filling in the downloaded file outside the NEN system, and then importing back into the NEN system. To download items into MS Excel, click on the "Export" button, and to upload the filled file, click on the "Import" button. This action can be repeated until the moment of submitting the tender.

image-20240314-143304.png

The process of inserting file attachments and completing the submission is completely identical to the usual submission process.

Variants of indicative tenders/ tenders

Variants of indicative tenders/ tenders

If the contracting authority allows submitting variant indicative tenders or tenders, you can create multiple tender variants within a single electronic submission by clicking on the "Add a variant" button. Forms for individual variants are identical. The process of inserting file attachments and completing the submission is completely identical to the usual submission process.
