Providing services to public companies is only possible through public bidding processes. Bidding processes are competitive procedures in which companies submit proposals to supply products or services to the public company. To participate in bidding processes, companies must be up-to-date with their legal obligations and have the technical and financial capacity to meet the requirements of the public company, which are proven through certificates of technical capacity. It is important that companies know the rules and regulations of public bidding processes to prepare adequately and increase their chances of success.
