Once a standing offer has been made, the service or agency works directly with you to obtain the necessary goods or services. Calls against a stationary tender are processed faster, are associated with less paperwork and have already set predefined prices and conditions. For taxpayers, the benefits are the reduction of the administrative costs of the state and the decrease in the stock. Standing offers are used to meet recurring needs when services or agencies repeatedly order the same goods or services. They can also be used when a service or agency expects a large number of goods or services to be needed for a given purpose; However, the actual needs are not known and delivery must be made when needed. Among the most common products purchased in this way are food, fuel, pharmaceuticals and sanitary products, tyres and pipes, stationery, office equipment and electronic data-processing devices. . . .
