This agreement is generally formalized by a contract and defines the relationship between the two parties, usually for the purposes of the parties, to cooperate closely continuously, under certain conditions, which benefit both parties. An EPI is usually prompted by the company that appoints one of its suppliers for close collaboration to obtain certain goods or services, as they feel that this provider is the best to obtain them. The Professional Services Agreement (PSA) is used as a “white agreement” to enter into a contract with a consultant for a specified period of time. If an institution is willing to use the advisor`s services, Schedule A (Written Authorization for Service Delivery) is executed. Figure A shows the services to be provided, the remuneration and the timetable for the performance of the services. Examples of this work are: soil surveys, environmental studies, planning, testing, cost estimation, etc. Through the use of a lifecycle services approach based on quality systems and tools, PSA leverages its know-how and provides different product and service groups and external supplier partners. This bundled service approach allows PSA to end the maintenance and operational maintenance of electrical systems, instruments, control systems and industrial networks. A Preferred Supplier Agreement (EPI) is an agreement between a company and one of its third-party suppliers. This often encourages the provider to maintain a high quality of service for the company informed.
When a company decides not to renew its PSA with its supplier, it creates opportunities for other suppliers, for the business of the company. By committing to an EPI, a company generally refrains from cooperating with alternative suppliers in direct competition with the supplier for PSA, which is advantageous for the supplier. In return, the supplier generally offers its goods or services to the company it has entered an EPI at a reduced price or makes them available under certain preferential conditions. As part of a superior support service, PSA Engineering has a team of site-based engineers who provide 24/7 control systems.
