My bank requests this automatically every year, my case manager apologizes every time for the automatic email. Ultimately, it doesn't matter as long as the installments are paid. For me personally, the house financing and business account are with the same bank. That was not planned originally, but it turned out that way. So my case manager already knows anyway, because he can see my business account. Whether I then send him the detailed profit and loss calculation or not, or whether a sack of rice falls in China, it makes no difference.
They are not completely stupid when it comes to financing self-employed people either, , with your company there are probably (pure speculation on my part) queries/information that can be easily retrieved without asking you. That is not so easily the case with me, for example, because I do not appear in the commercial register or similar, at most the credit score is accessible.
