This model is empirically tested with data obtained from the managers of 381 Portuguese companies. We use structural equation modelling in the analysis of causal relationships between different constructs. The results show that information and control systems quality (accounting and internal control) have a direct impact on Non-Financial Information Quality and an indirect impact on Decision-Making Success. The results also indicate that Quality Non-Financial Information does not contribute directly to Non-Financial Performance but contributes indirectly via DecisionMaking Success. The exploratory variables prove to be crucial for the companies’ Non-Financial Performance, accounting for its 62% variance. Previous research focuses primarily on financial information quality and financial performance. This study is the first to empirically prove that information and control systems contribute favourably to the transparency and value-relevance of non-financial information and, consequently, to business success.engAccounting information system qualityCorporate successNon-financial information qualityDecision-making successInternal control system qualityjournal article10.1016/j.accinf.2022.100557
