An effective accounting system provides accurate and timely financial information while meeting compliance requirements. It requires organization through separating duties and integrated software to avoid manual data re-entry. Careful planning is needed before implementation, including departmentalizing the general ledger to mirror business flows and using nomenclature for accounts and inventory that supports filtering and reporting for employees, customers, and vendors. The data structure must accommodate any stock numbering systems, standards, or software limitations to enable flexible reporting and compliance.
