after that, monthly fees (base + self-service) and the opportunity costs of manual processes continue to accrue each month. The payback period is the point at which the cumulative opportunity costs equal the cumulative investment (initial investment + monthly fees); it is expressed in days (1 month = 30 days). The additional workload per transaction (rounding, data entry, post-calculation\u2014all taking just seconds) is calculated as opportunity costs per employee using the number of transactions per day and the hourly rate, and then extrapolated to a monthly figure. For vacation and absence requests, the digital request is assigned the configured percentage of manual effort (employee + manager + HR); the difference is considered a savings per request and is extrapolated to a monthly basis using the number of requests per year. Both categories are added together for comparison, payback analysis, and charting.    <\/p>\r\n      <p class=\"zir-print-only\">ZMI GmbH \u00b7 www.ZMI.de \u00b7 Adolf-Kolping-Stra\u00dfe 11 \u00b7 97725 Elfershausen<\/p>\r\n    <\/section>\r\n\r\n  <\/div>\r\n<\/section>\r\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Investment Calculator: Digital Time Tracking and HR Processes Investment in the base module and self-service processes compared to the opportunity costs of manual time tracking and manual vacation\/absence requests\u2014per employee per month, including the degree of digitization.
