Ms. Köller is a director at a small carpentry, which she has inherited from her parents. As the boss of her firm Ms. Köller also takes care of the accounting.
Under certain conditions keeping account books and accounting is even a statutory provision for a company or self-employed person. Also the tax authority or investors, from whom Ms. Köller might wish to get credit, could request book keeping or getting an insight into the already existing accounting, respectively.
However, accounting is not only a chore to some, but can also help a company or self-employed person to keep control of the ongoing business operations and to improve the planning for future developments.
