Single Source Procurement (Direct Procurement)
Under Article 22 of Public Procurement Law No. 4734, single source procurement is the procurement of a requirement directly from a person, without conducting a notice and tender process, where competition cannot be ensured because the requirement can be met only by a single real or legal person, because a single person holds an exclusive right, or because technical compatibility and standardisation are essential. Typical examples are the renewal of a licence for patented software and the need to procure spare parts of a single brand compatible with the existing system.
