@Davide you are simply not correct that past figures cannot change. It’s happening all the time, even to the biggest companies where reported figures turned to be wrong due to software bug or user error (sometime the differences amount to millions of dollars). If that happens, the company is obligated to provide corrected figures. The idea that software bug will be fixed only for new periods is simply not acceptable.
Let me give you an example why…
Let’s say there is a software bug which causes your VAT liability to be underreported. When bug is fixed, it turns out you underpaid VAT to government by thousands of euros. By your account you say fixed bug must not affect past periods, you want this to be fixed for future periods only.
The government is not looking at it this way. As far as they are concerned, you owe them thousands of euros and they won’t accept your pricinple that past figures are not to be adjusted. They will want you to submit correction to your past figures and pay the difference.
Manager works on this principle. And this is why reaching bug-free status for Manager is so important so this never happens.
