Calculate a flat rate discount on a pro rata basis

Margit Mjeda

During settlement, the discount is not applied proportionally to the items, as expected, but deducted as a total amount from the final amount. The discount was entered as a lump sum — but this does not appear to be distributed proportionally to the individual items.

Incorrect calculation of the surcharge as a sum on invoice

Christopher Arzt

If a surcharge has been specified as a sum in a project, this is not taken into account as a percentage of the performance level of the service when creating an invoice but is also billed as a total amount. 
In our opinion, that is absolutely wrong. 
If, on the other hand, a percentage surcharge is specified in a project, the billing amount is calculated correctly. 
In the same way, the invoice amount should also be calculated as a sum when using a surcharge.

Feil, Claudia

We also have the same problem over and over again. The full amount of the lump sum discount is then deducted from the first advance invoice. We haven't found a solution to this yet either. However, this is very poor for liquidity, especially with larger package discounts. In our opinion, a lump sum discount should only be deducted in proportion to the settlement amount.
