A purchase agreement is a document describing the legally binding agreement between a company (the buyer) and the supplier that promises to sell products and/or services with detailed technical specifications and to comply with the terms of the agreement. In return, the buyer is required to recognize the goods/or the benefit and to pay the liability incurred. the importance that a purchasing function can play in the development of a contract within a PP organization for contracts on and below the threshold for the application of public procurement directives. The 2014 Public Procurement Directives allow the authorities to take environmental concerns into account. This is the case with the early acquisition, the purchase process itself and the execution of the contract. The exclusion and selection rules aim to ensure that contractors and subcontractors respect environmental law to a minimum level of compliance. Techniques such as life cycle calculation, specification of sustainable production methods and use of criteria for assigning environmental mark-up criteria are available to help contracting authorities identify environmentally friendly offerings.  A purchase agreement is a written agreement between a buyer and a seller in which the buyer agrees to acquire goods or/and services from the Seller in exchange for payment transactions. A purchase agreement defines each party`s obligations and usually contains detailed price lists, payment information, delivery conditions and other legal conditions. There are many types of purchase contracts, including fixed-price contracts, temporary and material contracts (T-M contracts), pay markets, work contracts, etc. Acquisition and acquisition are therefore much broader concepts than purchases. While once companies have accomplished everything they need independently, this may not be practical and cause you to make considerable costs and develop a poor quality product, both of which are bad for your business. That`s why your company should have a purchasing management process in place to find the best suppliers and suppliers and negotiate advantageous contracts that take into account the interests of both parties.
When a procurement agent negotiates a contract with the supplier on contractual terms, it is necessary to explain specific details about the specification and volume of materials, pricing, discounts, delivery plan and material packaging instructions. The contract also contains clauses to determine whether liquidated damages should apply in accordance with the treaty and defines the procedure for terminating the contract for certain reasons. When contracting public contracts (KK), contracting authorities and state-owned enterprises take environmental issues into account when bidding for goods or services. The aim is to reduce the impact of supply on human health and the environment.  According to page 372 of PMBOK, “Figure 12-5. Conduct Procurements Data Flow Diagram” displays the project charter as an outlet. But nowhere is Project Charter mentioned in carrying out the buying section process. So if you want to know how the project charter plays a role in this process, market fraud can be defined as obtaining dishonest advantage, preventing an obligation or loss of public property or various means during the procurement process by officials, contractors or others involved in the acquisition.
 An example is a kickback in which a dishonest supplier representative pays a dishonest representative of the buyer to choose the supplier`s offer, often at an excessive price.
