On July 14th, 2025, we published version 2.18.0 of our cross platform open source e-invoicing toolkit “Mustangproject”.
Since November 2020 we throw exceptions when importing incorrectly calculated invoices.
Despite our request in June 2023 to add this particular check to the standard was denied, we have now added this check to our validation: we now throw a warning if quantity * price (projected on basis amount + charges – allowances, rounded to the required two decimals) of an item is incorrect.
This check is possible because we fixed am issue 887 regarding the calculation of percentual item discounts. In the import, the according Arithmeticexceptions (no longer “Arithmetricexceptions”) are now no longer catched prematurely and can be handled by the application.
