 This section covers compliance of laws and regulations when obtaining a good or services from a vendor , supplier , or provider . The procurement requirement is established to ensure that such goods and services are obtained in an effective manner and in compliance laws and regulations , including the prohibition of conflicts of interest , the fair selection of vendors , provide open and free competition among vendors , etc . The suspension and debarment requirement establishes that certain non @-@ federal entities have been prohibited from participating in or receiving federal assistance for various reasons , including prior mismanagement of funds or previous non @-@ compliance of laws and regulations . This prohibition may be temporary ( suspension ) or indefinite ( debarment ; until specifically allowed by the government ) . When performing this purchase , the recipient must verify that the vendor , supplier , provider or their respective principals ( e.g. , owners , top management , etc . ) are not suspended , debarred or otherwise excluded by the federal government . This is done by checking the Excluded Parties List System ( EPLS ) maintained by the General Services Administration or by contacting the federal agency .
