Peculiarities of Accounting Practices in Francesco Datini’s Partnership in Pisa

This study examines how bookkeeping was used to determine the financial results of the Datini Partnership in Pisa in the late 14th century. It highlights the difference between accounting procedures in a medieval partnership and accounting procedures in individual medieval enterprises and over time. Building upon previous studies, the analysis of archival documents and the construction of a model of the flow of information between accounts and account books reveals the details of the bookkeeping procedures in the firm and a complete picture of the calculation of the financial result of the partnership in 1394. The study found that the need for the partnership to identify profits resulted in a change in the bookkeeping method for inventory that improved the information quality when used in the process of identifying operating results and the overall financial result.
