You don’t have to report the actual hours spent in the project. However, you shall report staff costs according to the task assignments issued beforehand and the amount you report shall be supported with documents showing the salary and social fees. The amount must as well be posted in the financial records for the project. It is strongly recommended that, if possible, the fixed percentage for a person is used for an automatic posting of the correct share of the staff cost on the project code in the financial records. Automatic triggers in the financial records reduces the risk of errors. If it is not possible to handle it with automatic triggers in the financial records it would be preferable if you report the amount of hours that correspond to the percentage according to the person’s task assignment. For example, if person A is assigned to work 20% in the project, you register the hours corresponding to this share. You never need to submit time sheets.
