Purpose The purpose of this paper is to explore if and how micro and small firms apply management accounting (MA) techniques. Design/methodology/approach The study is based on 36 semistructured interviews with micro and small firm owners/managers in Mexico. Content analysis is used to identify how these enterprises use MA tools. Findings Micro and small firms consistently use MA tools. Most of them have some sort of planning, set objectives, have a costing system – even if budgeting is unusual – and use one or two metrics to monitor performance. Research limitations/implications This is exploratory research with a limited and nonrandom sample. Only a limited number of MA tools were studied. Practical implications Micro and small firms’ use of MA tools. This is arguably important because these enterprises use these techniques in a way that is different from the traditional approach used in bigger corporations. A relevant implication emerging from the findings, as a contribution to practice would be the need to include MA for micro and small businesses in formal training and textbooks. Originality/value On top of providing and assessing empirical evidence on a debate that has been so far largely theoretical, and on the back of the relative weight of micro and small enterprises in any given economy, this paper aims at reinforcing awareness on the need to further the study of the decision-making process in such firms.

PurposeThe purpose of this research is to contribute to knowledge-building on microenterprises in emerging economies, by assessing the determinants that drive their use of accounting systems.Design/methodology/approachA probabilistic model was developed to determine the likelihood that a micro-firm would adopt an accounting registry system as a function of a series of contingencies and personal characteristics of their owners/managers. Data from the Microentrepreneurship Survey (EME), from the National Institute of Statistics of Chile for 2017 was used.FindingsThe findings suggest that access to external funds, the size and the use of technology strongly influence micro-firms' adoption of accounting systems.Research limitations/implicationsDespite the richness and scope of the data, direct measurements of entrepreneurial orientation and environmental uncertainty, both central variables of the contingency theory, were missing. Hence, duly justified proxies were applied. It is also likely that there would be other variables that also influence the probability of using accounting tools.Practical implicationsThe study contributes to a better understanding of microenterprises, and the factors that determine the use of accounting systems. The results highlight that public policies aimed at fostering microenterprises should facilitate access to technology and external funds. Consistent with previous studies, the authors’ findings highlight the importance of training owner/managers on issues related to their business.Originality/valueThis paper contributes to theory by arguably being the first study to confirm that contingency theory does explain the adoption of accounting systems in microenterprises in emerging countries.
