That sucks. I can see how it costs thousands of euros per year to do the annual financial statements, but 15 000? Is that common, or were there special circumstances?
The numbers I have seen for external costs range in the low thousands, but maybe that is wrong?
Yes, time spent is a problem, but then communicate it in form of TIME SPENT, not just inflate the costs into some arbitrary number so you can make it sound worse while whining. It's dishonest.
Time is money, and government isn’t supposed to get any discount coupon on it.
