During the past several years, a number of attempts have been made to develop computer applications for the farm business. However, none of them truned out properly applicable to small farms occupying more than 90% of the total agri-business in number as they failed to take it into consideration that small farm, typically a private busines is quite different by nature from the large-scaled farm corporate. Small-sized farming is usually done on the houshold basis, and thus there is no distinction between the household and the business economy. In addition, small farm managers are mostly lacking knowledge or skills of both computers and accounting. This study, therefore, aims at the design and implementation of the financial management and accountign information system for small farms, with an attempt to relax constraints and resolve pitfalls revealed in previously developed applications. The following principles were introduced for the study : 1) The user-system interfaces have to be managed in the natural language as much as possible, so that the users can operate the system without any professional terms. 2) Household accounting has to be seperarte by some means from the business accounting, so that small farm businesses can manage their finance and accounting as necessary. 3) The system has to be designed so as not only for the users to manage transactional data but to analyse historical data in multiple dimensions for their decision-makings. The results from this study would perhaps help not only for the farmers but for the educators, policy makers, and counselors for the farming.
