ERP systems and management accounting: a multiple case study

Purpose The present study seeks to refine the findings and theory on the impact that enterprise resource planning (ERP) implementations have had on management accounting. Specifically, the purposes of this paper are to analyze the changes that ERP implementations have had on performance measures, management accounting techniques, activities of management accountants, and the use of non‐financial information. Design/methodology/approach The controllers of 13 major Canadian firms were interviewed as part of a multiple case study. Open‐ended questions were used. Findings The research assesses how ERP implementations through more computational power, relational databases, standardized state‐of‐the‐art transaction processing, and extended chart of accounts change management accounting. The enhanced computing power and overall standardization lead to more accurate and timely information. The standardized transaction processing and the charts of accounts have increased the availability of information from units and products previously deficient of information, and ensured a consistency of information across all units and products. The standardization and automation of transaction processing has reduced the amount of data entry done by management accountants. Performance measures have been standardized, expanded to more units and products, increased in accuracy, and produced more quickly. Management accounting techniques have become more efficient and effective. Management accountants are less involved with data entry, thus allowing them to undertake more analyses. Non‐financial information is more extensive. Originality/value This research provides new insights or contributions to understanding how ERP systems impact management accounting and management accountants. First, ERP system implementations affect management accounting. Second, the three part lens or conceptual framework – physical, transactional, and information – explicates the impact of ERP systems on management accounting and management accountants. Third, understanding the impact is further guided by recognizing the expanded chart of accounts inherent with ERP systems.
