First, suppliers must participate in the centralized competitions announced by CPO LT, published on CVP IS.

Competitions for the CPO LT e-catalog are conducted in one of the following ways: Open competition or Restricted competition based on a dynamic purchasing system (DPS).

You can learn about the necessary steps to become a supplier in the CPO LT e-catalog here: For Suppliers – Central Purchasing Organization – CPO LT

Supplier selection is conducted in one of the following ways:
by dynamic purchasing system (DPS) or by open competition.

• First, you should familiarize yourself with the published announcement about supplier selection for a specific module (all information about procurements—supplier selections can be found: Competitions, market consultations, and technical specifications – Central Purchasing Organization – CPO LT
• After reviewing the documents provided in the CVP IS system, to which you will be directed, and agreeing to participate in the supplier selection, click "accept invitation" and then follow the provided contextual aids.

If supplier selection is conducted based on DPS:

• During the validity of DPS, suppliers can submit applications at any time during the validity of DPS without the need to submit price offers in advance, selected suppliers will submit them only to the contracting authorities when offering their goods, services, or works in specific orders already in the CPO LT catalog.
• Suppliers are subject to only minimal qualification requirements and requirements for the absence of grounds for exclusion.
• Suppliers submit applications for compliance with qualification requirements and the absence of grounds for exclusion. Prices are not submitted at this stage.
• CPO LT evaluates the received applications and informs the Suppliers about the confirmation that they have been accepted to participate in DPS.
• For suppliers accepted into DPS, participation in specific orders in the CPO LT catalog is not mandatory, i.e., the supplier has the opportunity to choose orders relevant to them.

If supplier selection is conducted based on Open competition:

• Suppliers submit proposals for compliance with qualification requirements and the absence of grounds for exclusion, submitting preliminary (maximum prices/rates, which can only be reduced in a specific Procurement).
• CPO LT evaluates the received proposals and prices (rates).
• Selected Suppliers are invited by CPO LT to sign preliminary contracts.
• The preliminary contract specifies whether participation in specific orders in the CPO LT catalog is mandatory/non-mandatory.
• Secondly, i.e., when you are invited to participate in the CPO LT catalog, we will provide you with login (identification) data (you can familiarize yourself with the CPO LT catalog –catalog.cpo.lt)
• After registering in the catalog, you will be informed about the announced orders of contracting authorities by separate notifications via email.

When suppliers are invited to join the dynamic purchasing system (DPS), they can do so at any time until the end of DPS validity. Suppliers participating based on open competition are selected for a specific period. You can familiarize yourself with the method of selection into the CPO LT e-catalog module in the catalog assortment in the Procurement description next to each module: catalog.cpo.lt - Catalog

After the competition ends, CPO LT concludes preliminary contracts with the selected suppliers (in the case of Open competition) or confirms participation in the dynamic purchasing system (DPS).

Only registered supplier representatives can participate in the CPO LT catalog (after the competition ends, the supplier completes and submits a registration application to CPO LT).

• Must meet the qualification requirements set out in the conditions of CPO LT competitions.
• Must win a public procurement competition and conclude a preliminary contract for the supply of goods, services, or works through the CPO LT catalog or be confirmed in the DPS.
• Must publish and update their descriptions of goods, services, or works in the CPO LT catalog.
• Submit proposals during the order and, upon winning, must sign a contract with the PO.
