If there are fees that are only valid within a certain period (e.g. for one year), it is possible to use the percentage fees in Mercury:

  • Fees on media costs
  • Fees on discount-in-kind
  • Fees on discounts qualified as non-standard discounts

to such a condition.

When creating fee models in the category settings (see also How do I create a new fee model?), the use of a percentage fee can be restricted to a specific runtime. Only if the runtime of the plan item is within the fee runtime, will Mercury list the fee as a selection option.

On the one hand, this function helps to ensure that only the currently valid fees can be used and, on the other hand, provides a better overview, as obsolete (old) fees, are no longer displayed.
