For every entrepreneur, one of the key issues is the formulation and organization of accounting. This is not surprising: without well-functioning accounting, the normal functioning of any business entity is in principle impossible. Let us note right away: in our time, it is necessary to combine debits with credits only with the help of special software tools. After all, manual accounting not only takes a lot of time; its quality leaves much to be desired, and in most cases is unacceptable in principle: it is cumbersome, clumsy, uninformative, replete with errors and takes a huge amount of effort and time. The proposed book talks about simple and at the same time effective software products specifically designed to automate the accounting of an individual entrepreneur or small company.
