These changes can be done for several workers at the time, but the different types of hourly rates you wish to update must be updated individually. That is, one Excel sheet update for every type of hourly rate : Salary, Average shared cost and so forth. It is also worth mentioning that updating the files in this manner will also update reports back in time. This can be useful if you have used other ERP or project-management systems earlier and you wish to maintain a proper overview of earlier hourly rates. This will change key economic information, but is a great tool to plan for future indexed wage changes and other similar situations.
