Abstract. This research study is aimed, based on empirical evidence, at measuring the relationship
between the use of the Accounting Information Systems (AIS) by the Small and Medium Sized
Enterprises (SMEs) in Spain, and firms’ improved performance indicators and productivity. This
empirical study is based on a survey carried out among small and medium-sized firms to ascertain
the extent to which development and implementation of accounting information systems had taken
place, and subsequently an analysis was made as to how much this introduction may impact on
improvement in outcome indicators and productivity. As interesting results we have found that there
is a positive relationship among the SMEs that use AIS for fiscal and bank management and better
performance measures. This research provides value added in accounting literature given the
scarcity of works dealing with the relationship between the application and use of AIS and
performance and productivity indicators in SMEs in Spain.
