As part of the HE purchasing consortia’s national printer agreement, Duncan Allison from the University of Bolton developed a Total Cost of Ownership Tool. This tool will help you identify the individual costs relating to the procurement of printer equipment. These can be either one-off or recurring costs. One-off costs are sunk once the acquisition is made whereas recurring costs are time dependent and continue to be incurred throughout the life of the product or service. Furthermore, recurring costs can increase with time for example through increased maintenance costs as equipment ages.
