The branch of accounting that serves as a bridge between financial and managerial accounting is cost accounting.
Cost accounting focuses on the analysis, allocation, and control of costs to help management make informed decisions. It measures and reports the costs associated with producing goods or services, and provides information on the profitability of different products, departments, or projects.
